Answers

Answer 1

Answer:

C. 120

Step-by-step explanation:

The figure shows that angles BEC and KEC are congruent. Their measures are equal.

m<KEC = m<BEC

10x = 6x + 24

4x = 24

x = 6

m<BEK = 2m<KEC

m<BEK = 2 * 10x

m<BEK = 2 * (10)(6)

m<BEK = 2 * 60

m<BEK = 120

Bennett brings 3 gallons of water to his football game. His teammate, Jordan, brings 3 times as many gallons of water as Bennett. If one gallon of water contains 128 fluid ounces, how many ounces of water did Bennett and Jordan bring to their football game?

Answers

Answer:

It could be 768 fl. oz I think?

Step-by-step explanation:

Bennett has 3 gallons of water and Jordan has 3 times as many gallons as bennett

Let's calculate how many gallons do Jordan has

3*3 = 9

Jordan has 9 gallons of water

every gallon of water contains 128 fluid ounces

Benett

Benett has 3 gallons

so  the fluid ounces are given by : 3*128=384

Benett has 384 ounces

Jordan

Jordan has 9 gallons so 9*128 = 1152

so Jordan has 1152 fluid ounces

Please help I’m being timed!! The computer rendering of a mural in a town’s square uses the function represented in the table to define the outline of a mountain in the town’s logo, where x is the distance in feet from the edge of the mural and f(x) is the distance from the ground in feet. How can the point (12, 16) be explained? A) The highest point of the mountain defined by the function is 12 feet. B) The highest point of the mountain defined by the function is 16 feet. C) The width of the base of the mountain defined by the function is 12 feet. D) The width of the base of the mountain defined by the function is 16 feet.

Answers

Answer:

The correct option is;

B) The highest point of the mountain defined by the function is 16

Step-by-step explanation:

From the given information, we have;

The distance in feet from the edge of the mountain is given as the independent variable, x

The distance in feet from the ground (which is the height) is given the as the dependent variable f(x)

Therefore, given that the point (12, 16) are the values of x and f(x) such that x = 12 and f(x) = 16 and 16 is the largest value of f(x) in the data, therefore, 16 represents the highest defined point of the mountain.

Answer:

m∠D = 94°

Step-by-step explanation:

Quadrilateral ABCD is also called a cyclic quadrilateral or a quadrilateral that is inscribed in a circle.

Opposite angles in a cyclic Quadrilateral are supplementary, i.e the sum of two opposite angles in a Quadrilateral = 180°

m∠A + m∠C = 180°

m∠A = 74°

74° + m∠C = 180°

m∠C = 180° - 74°

m∠C = 106°

In a cyclic quadrilateral, the total sum of the angles outside the circle = 360°

i.e =

m∠AB + m∠BC + mDC + mAD = 360°

m∠DAB= ( m∠C) × 2

= 106° × 2 = 212°

m∠DAB = m∠AD + m∠AB

m∠AD = 79°

212° = 79° + m∠AB

m∠AB = 212° - 79°

= 133°

m∠ABC = m∠AB + m∠BC

m∠AB = 133°

m∠BC= 55°

m∠ABC = 133° + 55°

= 188°

We are asked to find m∠D

m∠D = 1/2m∠ABC

m∠ABC = 188°

m∠D = 1/2 × 188°

m∠D = 94°

Therefore, m∠D = 94°

Now we need to find the length of the arc.

Since the missing part of the circle is labeled with a right angle, we know that it's exactly 1/4 of the whole circle. That means the arc we need to find is 3/4 of the circumference.

technical problems, the programme had to be cancelled. If Pak Kamil sells all the fish and vegetables for RM8 and
RM0.50 per kilogram, respectively, what is the total loss experienced by Pak Kamil? Show your calculations.
TP 6​

Answers

Answer:

The total loss experienced by Pak kamil is RM74

Step-by-step explanation:

The cost of 10 kg and  6 kg of vegetables = RM 136

The cost of 4 kg fish and 2 kg of vegetables = RM 54

Amount for which the fish was sold = RM8 per kilogram

Amount for which the vegetables was sold = RM0.50 per kilogram

The total mass of the fish = 10 kg + 4 kg = 14 kg

The total mass of the vegetables = 6 kg + 2 kg = 8 kg

The amount for which the meat was sold = 14 kg × RM8/kg = RM112

The amount for which the fish was sold = 8 kg × RM0.50/kg = RM4

RM112 + RM4 = RM116

The total amount for which the fish and vegetable was sold = RM136 + RM54 = RM190

Therefore, the total loss experienced by Pak kamil = RM190 - RM116 = RM74.

The solution for x2 + 2x + 8 ≤ 0 is

Answers

Answer:

Please use " ^ " for exponentiation: x^2 + 2x + 8 ≤ 0.

Let's solve this by completing the square:

x^2 + 2x + 8 ≤ 0 => x^2 + 2x + 1^2 - 1^2 + 8 ≤ 0. Continuing this rewrite:

(x + 1)^2 + 7 ≤ 0

Taking the sqrt of both sides: (x + 1)^2 = i*sqrt(7)

Then the solutions are x = -1 + i√7 and x = -1 - i√7

Answers

Answer:

B. [tex]100 = 132.12sin2\theta[/tex]

Step-by-step explanation:

Given the horizontal distance in meters traveled by a projectile modeled by the function [tex]h = \frac{v_o^{2} }{4.9}sin\theta cos\theta[/tex]. If the initial velocity is 36 meters/second, the equation we would you use to find the angle needed to travel 100 meters is shown below;

[tex]h = \frac{v_o^{2} }{4.9}sin\theta cos\theta[/tex]

from trigonometry identity,

[tex]sin2\theta = 2sin\theta cos\theta\\sin\theta cos \theta = \frac{sin2\theta}{2}[/tex]

The equation will become;

[tex]h = \frac{v_o^{2} }{2*4.9}(sin2\theta)\\[/tex]

[tex]h = \frac{v_o^{2} }{2*4.9}sin2\theta[/tex]

Given h = 100 meters and v = 36 m/s

[tex]100 = \frac{36^{2} }{9.8}sin2\theta\\100*9.8 = 1296sin2\theta\\100 = \frac{1296}{9.8} sin2\theta\\100 = 132.12sin2\theta[/tex]

What is the height of the prism if there is 30 square centimeters and the volume is 90 cubic centimeters

Answers

Answer:

the height of the prism =3cm

Step-by-step explanation:

From the question :there is 30 square centimeters, we can deduce this is the area due to the unit

the volume is 90 cubic centimeters

Volume of prism = Area of base × height

We are to determine the height

90cm³ = 30cm² × height

divide both sides by 30cm²

height = 90cm³/30cm²

height = 3cm

Therefore the height of the prism is 3centimeters

Pls hurry! Will make brainliest!! What is the formula that relates circumference and diameter?

Answers

Answer:

Circumference = πd

where d = diameter

Step-by-step explanation:

When using this formula you don't need to multiply by 2 like you do when using the radius because the diameter is twice the radius of a circle.

Answer:

There are actually two formulas c=πd or pi=c/d.

Step-by-step explanation:

This is how they relate to each other. Let's say you were to isolate for pi. So, for 2pir, we have to divide both sides by 2r or the diameter. 2r=d because the diameter is equal to having two radii or radiuses. When you isolate pi, you will see that pi= to the circumference, c, divided by the diameter, d. Therefore, you can say that the circumference is approximately 3.14 or pi times greater than the diameter. In fact, that is what pi is. It is a ratio that shows the relationship between the circumference and the diameter. In other words, pi=c/d. Hope this helps!

A 99% confidence level is saying that you are 99% positive that you null hypothesis will not be rejected. The critical value that comes with the confidence level is the Z-score. The Z-score can usually be found using the Z-score table found online. The Z-score for 99% confidence is 2.575. If they give you the Z-score and tell you to find it on a right tail graph you subtract the given z-score from alpha which is .5 and find what you got on the z-score table.

Ex: Given Z-score- 0.0079

.0079 - .5(alpha)=  0.4921.

The closest area to 0.4921 is 0.4922 at z = 2.42.

y +7

y - 8

Find the number after y+

Answers

y^2 + 15y + 56 factors to (y+7)(y+8)

This is because 7+8 = 15 is the middle term and 7*8 = 56 is the last term. We can use the box method, FOIL rule, or distributive property to confirm we have the right factorization. I'll use the distributive rule

(y+7)(y+8) = y(y+8) + 7(y+8)

(y+7)(y+8) = y^2 + 8y + 7y + 56

(y+7)(y+8) = y^2 + 15y + 56

A rectangular piece of paper has an area of 24 square inches. You trim the paper so that it fits into a square frame by trimming 3 inches from the length and 1 inch from the width of the paper. Write and solve an equation to find the side length of the resulting square paper.

Answers

Answer:

Length of the square = 3 inches

Equation:   [tex]l = L - 3[/tex] and [tex]l = W - 1[/tex]

Step-by-step explanation:

Given

Area of the rectangle = 24

Required

Length of the square when the dimension of the rectangle is trimmed by 3 inches * 1 inches

Represent the dimension on the rectangle by L and W

Such that L represent Length and W, Width

This implies that

[tex]L * W = 24[/tex]

Represent the length of the rectangle by l

Such that

[tex]l = L - 3[/tex] and [tex]l = W - 1[/tex] (When trimmed)

Equate both expressions

[tex]L - 3 = W - 1[/tex]

Add 3 to both sides

[tex]L - 3 + 3 = W - 1 + 3[/tex]

[tex]L = W + 2[/tex]

Next is to list all possible dimensions of the rectangle;

[tex]Area(L,W) = Length * Width[/tex]

[tex]Area(24,1) = 24 * 1 = 24[/tex]

[tex]Area(12,2) = 12 * 2 = 24[/tex]

[tex]Area(8,3) = 8 * 3 = 24[/tex]

[tex]Area(6,4) = 6 * 4 = 24[/tex]

From the list above, the only calculation that fits our solution is

[tex]Area(6,4) = 6 * 4 = 24[/tex]

Such that

[tex]6 = 4 + 2[/tex]

By direct comparison of [tex]6 = 4 + 2[/tex] to [tex]L = W + 2[/tex];

[tex]L = 6[/tex]

[tex]W = 4[/tex]

Recall that

[tex]l = L - 3[/tex] and [tex]l = W - 1[/tex]

Substitute 6 for L and 4 for W

[tex]l = 6 - 3[/tex] and [tex]l = 4 - 1[/tex]

[tex]l = 3[/tex] in both cases

Hence, the length of the square is 3 inches

And the equation is  [tex]l = L - 3[/tex] and [tex]l = W - 1[/tex]
