Are the following angle relationships possible? Explain.

Answer:

22.33%

Step-by-step explanation:

First, divide 67 by 300. Next, take this result and multiply it by 100

67÷300=0.2233

0.2233×100=22.33

So the answer is 22.33%

Answer:

False

Step-by-step explanation:

To be able to answer this, we will need to make a reference to the sum and product formula.

What we have in the question is the product and we want to see if the sum correlates.

Using the sum formula, we have the value on the right hand side as;

(1/2)[sin(x+y)+sin(x-y)]

Seeing that the expression we have here is not equal to that which was given, we can conclude that the answer is false

Answer:

1. Find the difference between the areas.

Area of the small rectangle: [tex](x+2)(x+7)=x^2+7x+2x+14=x^2+9x+14[/tex]

Area of the big rectangle: [tex](x+9)(x+11)=x^2+11x+9x+99=x^2+20x+99[/tex]

The difference is: [tex]11x+85[/tex]

[tex]( x^2+20x+99)- (x^2+9x+14)=x^2+20x+99-x^2-9x-14=11x+85[/tex]

2.

You can solve this question just by looking at the graph.

a) The height is 4 meters.

[tex]f(d)=h=-2d^2+7d+4[/tex]

To find the height of the bleachers, we should consider the moment before the shoot, when the distance is equal to 0.

[tex]f(0)=h=-2(0)^2+7(0)+4[/tex]

[tex]h=4[/tex]

The height is 4 meters.

b) 9 meters.

For [tex]d=1[/tex]

[tex]f(1)=h=-2(1)^2+7(1)+4[/tex]

[tex]f(1)=h=-2+7+4[/tex]

[tex]h=9[/tex]

b) The ball travels 4 meters.

But to calculate it, it is when [tex]h=0[/tex]

[tex]0=-2d^2+7d+4[/tex]

Using the quadratic formula:

[tex]$d=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$[/tex]

[tex]$d=\frac{-7 \pm \sqrt{7^2-4\left(-2\right)4}}{2\left(-2\right)}$[/tex]

[tex]$d=\frac{-7\pm\sqrt{81}}{-4}$[/tex]

[tex]$d=\frac{-7\pm9}{-4}$[/tex]

It will give us to solutions, once it is a quadratic equation, but we are talking about a positive distance.

[tex]$d=-\frac{1}{2} \text{ or }d=4$[/tex]

3.

In this question, we have to find the area of the cylinder and the sphere.

From the information given, we have

a = 5mm and d = 5mm, therefore the radius is 2.5 mm.

The volume of a cylinder:

[tex]V=\pi r^2h[/tex]

[tex]V=\pi (2.5)^2 \cdot 5[/tex]

[tex]V=31.25 \pi[/tex]

[tex]V_{c} \approx 98.17 \text{ m}^3[/tex]

The volume of the sphere:

[tex]$V=\frac{4}{3} \pi r^2$[/tex]

[tex]V_{s} \approx 65.4 \text{ m}^3[/tex]

The volume of the capsule is approximately [tex]163.57 \text{ m}^3[/tex]

Answer:

Step-by-step explanation:

The cost of the new car is $20,000.

We would apply the periodic interest rate formula which is expressed as

P = a/[{(1+r)^n]-1}/{r(1+r)^n}]

Where

P represents the monthly payments.

a represents the amount of the loan

r represents the annual rate.

n represents number of monthly payments. Therefore

a = $20000

r = 0.05/12 = 0.0042

n = 12 × 5 = 60

Therefore,

P = 20000/[{(1+0.0042)^60]-1}/{0.0042(1+0.0042)^60}]

20000/[{(1.0042)^60]-1}/{0.0042(1.0042)^60}]

P = 20000/{1.286 -1}/[0.0042(1.286)]

P = 20000/(0.286/0.0054012)

P = 20000/52.95

P = $378

Ahmed will pay $378 each month

The total payment is

378 × 60 = $22680

The amount that Ahmed will pay in interest is

22680 - 20000 = $2680

It is simple.

To find the correct values plug a x value.

For Example;

X=1

y=5(1)+4

y=5+4

y=9

so your X value is 1 and your Y value is 9

To solve for the incorrect values

Find the correct values and subtract 1 form the Y value.

Answer:

346.4 cm^2

Step-by-step explanation:

area = base * height/2

We can use UW as the base.

U + V + W = 180

24 + V + 36 = 180

V = 120

[tex] \dfrac{\sin W}{UV} = \dfrac{\sin V}{UW} [/tex]

[tex] \dfrac{\sin 36^\circ}{34} = \dfrac{\sin 120^\circ}{UW} [/tex]

[tex] UW = \dfrac{34\sin 120^\circ}{\sin 36^\circ} [/tex]

[tex] UW = 50.1 [/tex]

Now drop a perpendicular from V to UW to be the height, h.

[tex]\sin 24^\circ = \dfrac{h}{UV}[/tex]

[tex] \sin 24^\circ = \dfrac{h}{34} [/tex]

[tex] h = 34 \sin 24^\circ [/tex]

[tex] h = 13.8 [/tex]

area = base * height/2

area = UW * h/2

area = 50.1 cm * 13.8 cm/2

area = 346.4 cm^2

Answer:

-59.5

Step-by-step explanation:

We are given the expression

-3|t − 8| + 1.5

t = -12

Subtituting -12 for t in the expression, we have:

-3|-12 - 8| + 1.5

-3|-20| + 1.5

Note : |-20| = 20

-3 × 20 + 1.5

= -60 + 1.5

= -59.5

The value of the expression = -59.5

Answer:

Step-by-step explanation:

[tex] - 2x + 3 = 9 \\ - 2x = 9 - 3 \\ - 2x = 6 \\ \frac{ - 2x}{ - 2} = \frac{6}{ - 2} [/tex]

[tex]x = - 3[/tex]

Answer: x = -3

Step-by-step explanation: To solve for x, we must first isolate the term containing x which in this problem is -2x.

Since 3 is being added to -2x, we subtract 3 from

both sides of the equation to isolate the -2x.

On the left, the +3 and -3 cancel out and on the right, 9 - 3 is 6.

So we have -2x = 6.

Now we can finish things off by just dividing

both sides of the equation by -2.

On the left the -2's cancel and on right, 6 divided by -2 is -3.

Thus, the solution to this equation is x = -3.

Answer:

David scored : 24 < 6x = 0

Step-by-step explanation:

From the information given;

David  scored ??? points less than six times the number of points Rich scored in a video game.

If  ???   represents the number of points scored by Rich

The objective is to write an expression representing the number of points scored by David.

since the value of David points and Rich letter representing the number of points scored by RIch  are not given,  Let's based our calculation on assumptions, the main thing is to understand the the process in solving the question.

Assumption:

Let assume that,

David scored 24 points and x should be the number of points scored by Rich

Then; the linear equation representing David score is:

David scored : 24 < 6x = 0

Answer:

C. p > -3

Step-by-step explanation:

We observe the characteristics of the shaded ray on the number line.

It goes to the right, so the inequality must be either greater than or greater than or equal to.

The circle where it starts on is open, so the inequality must not be less than or equal to or greater than or equal to.

Now, without even looking at the numbers themselves, we can find our answer.

There are four different types of inequalities, and we eliminated three of them (<, <=, >=). This leaves only one left (>). The only answer choice that uses the greater than symbol is C, so it must be our answer.

Sample Answer: First determine the integers the x-coordinate and the y-coordinate are between. Then look at each to decide which integer the x- or y-value is closer to, and approximate the coordinate value to the tenths place.

Step-by-step explanation:

To estimate to the tenths place, you have to determine the actual solution and the approximate.

Assume the solution to the system of equation is:

[tex]\mathbf{(x,y) = (1.25, 1)}[/tex]

1.25 is to the hundredth place.

So, the next thing is to approximate 1.25 to 1.3 (the tenth place).

So, we have:

[tex]\mathbf{(x,y) = (1.3, 1)}[/tex]

Hence, the actual solution must be approximated to the tenths place.

We want to see which of the formulas is a correct rearrangement of d=rt. To figure this out, we will solve each of our answer options for d. If d is equal to rt, then that option is the correct rearrangement.

OPTION A

t=d/r

We flip the equation around so d is on the left side.

d/r=t

We multiply both sides by r.

d=tr

Using the associative property, we see that d=tr is the same thing as d=rt.

We immediately see that this is the correct option. Therefore, the answer is A. T=d/r.

From the original d=rt, equation, we see that they solved for t by dividing both sides by r, giving you t=d/r.

The distribution for town A is positively skewed, but the distribution for town B is symmetric.

============================================================

Explanation:

The length of the whiskers tell us if we're dealing with a symmetric distribution, or a skewed distribution. For town A, the right whisker is longer than the left whisker. So this distribution is positively skewed. We can say it is skewed to the right, or right skewed.

Town B has whiskers of equal length. In addition, the two distances inside the box are equal to one another. We have a perfectly symmetric distribution. One half is a mirror copy of the other half.

Answer:

Hey there!

This is a box and whisker plot, and since the right whisker is longer, this is positively skewed. (For town A)

This is also a box and whisker plot, and since it is even on both sides, it is symmetric.

Answer:

D. x = 2 − √7 and x = 2 + √7

Step-by-step explanation:

-x² + 4x + 3 = 0

Multiply both sides by -1.

x² − 4x − 3 = 0

Factor using quadratic formula.

x = [ -b ± √(b² − 4ac) ] / 2a

x = [ -(-4) ± √((-4)² − 4(1)(-3)) ] / 2(1)

x = (4 ± √28) / 2

x = (4 ± 2√7) / 2

x = 2 ± √7

x = 2 − √7, 2 + √7
