Answer:

30(-2) = -60

Step-by-step explanation:

The change in speed from a higher location to a lower location is 2 m/s, v = -2 m/s (from higher to lower)

We need to find the equation that models the change in the bird's position at 30 seconds.

Distance = speed × time

change in position = (-2) × 30

= -60

Hence, the correct option is (B).

Step-by-step explanation:

a has a positive before negative, so its ruled out

1.3 is more than -0.45, so b is ruled out

everything in c is in the right order. -1/2 is -0.5 and -2/3 is -0.66, 7/12 is -.58

d is incorrect because -2/3 isnt more than 7/12

Answer:

2.3 hours

Step-by-step explanation:

161 divided by 70 = 2.3

if Carlos drives 161 kilometers at a speed of 70 kilometers per hour then it takes 2.3 hours to drive.

Speed is the time rate at which an object is moving along a path,

Given,

Carlos drives 161 kilometers at a speed of 70 kilometers per hour

From the given data distance=161 kilometers

Distance is one hundred sixty one kilometers

Speed=70km/hr.

Speed is seventy kilometer per hour.

Speed=Distance/time

70=161/time

Now cross multiply

time=161/70

Time=2.3hrs

Hence, if Carlos drives 161 kilometers at a speed of 70 kilometers per hour then it takes 2.3 hours to drive.

Answer:

the onw haldf

Step-by-step explanation:

Answer:

The answer is no he is not correct, here's why.

C) No, he subtracted 1 and 9 instead of adding.

Step-by-step explanation:

Jerrod has found the hypotenuse, with the legs of 3 ft and 1 ft, his process is:

[tex]c^{2}[/tex] = 32 + 12

[tex]c^{2}[/tex] = 9 + 1

[tex]c^{2}[/tex] = 8

c = 8

The legs Jerrod said are 3 ft and 1 ft

so A and B of the formula of pythagorean theorem could be:

[tex]a^{2}[/tex] = (3)[tex].^{2}[/tex]

[tex]b^{2}[/tex] = (1)[tex].^{2}[/tex]

This leads us to:

[tex]3^{2} + 1^{2} = c^{2}[/tex]

which is:

9 + 1 = [tex]c^{2}[/tex]

10 = [tex]c^{2}[/tex]

In this case, Jerrod had calculated wrong by instead of adding he had subtracted.

(I don't know where he got 32 + 12, but other than that his process is correct other than calculation error)

The correct statement for given situation is,

⇒ No, Jerrod made an error to finding the square root.

Any triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

Jerrod found the hypotenuse of a right triangle with legs 3 ft and 1 ft.

With steps are,

⇒ c² = 3² + 1²

⇒ c² = 9 + 1

⇒ c² = 8

⇒ c = 8

Now,

We have the steps are,

⇒ c² = 3² + 1²

⇒ c² = 9 + 1

⇒ c² = 8

⇒ c = 8

Clearly, In fourth step we get;

If c² = 8

Then, c = √ 8

But here we have;

⇒ c² = 8

⇒ c = 8

Hence, He made an error finding the square root.

Therefore, The correct statement for given situation is,

⇒ No, Jerrod made an error to finding the square root.

Step-by-step explanation:

Answer:

A quick estimated answer would be 5,000-5,100

Step-by-step explanation:

Answer:

Leo started with $260

The balance of Vanessa and Leo after 7 weeks = $120

Step-by-step explanation:

Vanessa started $400

Vanesaa spending rate= $80/2weeks

In a week she would spend=$40/week

In 7 weeks should spend =40*7 = $280

Her balance after 7 weeks is =

$400 - $40 × x

$400 - $280

= $120

Leo spends at half of vanessa’s rate= $20/week

In 7 weeks leo will spend

$20 × x weeks

= 20 × 7 = $140

Since Leo and Vanessa’s balance would be the same after 7 days then leo balance is $120

Hence, the amount Leo started with $120 + $140= $260

In order to confirm your above answer

The Equation can be given as

$400 - $40 ×x = $260 - $20 × x

Where x = 7 weeks

$400 -40x = 260 - 20x

$400 - 40× 7 = $260 - 20× 7

$400 - 280 = $260 - 140

$120 = $120

Answer:

Real, Rational, Integer,

Step-by-step explanation:

Real: Most numbers are real so they just naturally fall into this category

Rational: -5 can be written as a fraction so it falls here

Integer: An integer is a number that can be positive, negative, or 0. as long as it doesnt have decmal points, it's an integer

Its not a whole number because whole numbers cannot contain a fraction, decimal, or negative value

Answer:

The third is correct.

Step-by-step explanation:

Preimage: A(2,3), B(5,6), C(8,6), D(8,3)

Image: A'(-2, 6); B'(-5,3); C'(-8,3); D'(-8,6)

Option 3.

                Translation              Rotation 180° Clockwise

                   (x, y-9)                              (-x,-y)

A(2,3)            (2,-6)                              A' (-2,-6)

B(5,6)            (5,-3)                              B' (-5,3)

C(8,6)            (8,-3)                              C' (-8,3)

D(8,3)            (8,-6)                               D' (-8,6)

Transformation involves changing the position of a shape.

The sequence of transformation is: (d) A translation rule by [tex]\mathbf{(x,y) \to (x, y - 9)}[/tex] and then a 180 degrees clockwise rotation about the origin

The coordinates of the pre-image is:

[tex]\mathbf{A = (2,3)}[/tex]

[tex]\mathbf{B = (5,6)}[/tex]

[tex]\mathbf{C = (8,6)}[/tex]

[tex]\mathbf{D = (8,3)}[/tex]

Of the given sequence of transformations, option (d) is correct.

The proof is as follows.

First, translate ABCD by (x, y - 9)

So, we have:

[tex]\mathbf{(x,y) \to (x, y - 9)}[/tex]

[tex]\mathbf{(2,3) \to (2, -6)}[/tex]

[tex]\mathbf{(5,6) \to (5, -3)}[/tex]

[tex]\mathbf{(8,6) \to (8, -3)}[/tex]

[tex]\mathbf{(8,3) \to (8, -6)}[/tex]

Next, rotate by 180 degrees.

The rule of this transformation is:

[tex]\mathbf{(x,y) \to (-x,-y)}[/tex]

So, we have:

[tex]\mathbf{(2,-6) \to (-2,6)}[/tex]

[tex]\mathbf{(5,-3) \to (-5,3)}[/tex]

[tex]\mathbf{(8,-3) \to (-8,3)}[/tex]

[tex]\mathbf{(8,-6) \to (-8,6)}[/tex]

From the graph, the coordinates of the image are:

[tex]\mathbf{A" = (-2, 6)}[/tex]

[tex]\mathbf{ B" = (-5,3)}[/tex]

[tex]\mathbf{C" = (-8,3)}[/tex]

[tex]\mathbf{D" = (-8,6)}[/tex]

Hence, the sequence of transformation is:

(d) A translation rule by [tex]\mathbf{(x,y) \to (x, y - 9)}[/tex] and then a 180 degrees clockwise rotation about the origin

add $7.15 to $7.20 and you get $14.35

thats the gross profit, and you subtract that by $7.50, how much she bought the mangos for, to get her total net profit.

Answer:

64 ounces

Step-by-step explanation:

Given.

Represent blue with b and yellow with y

b = 3

y = 8

Required

What's the value of y when b = 24

Represent the given and required parameters as ratio

3 : 8 and 24 : y

Turn the ratio to an equation

3 : 8 = 24 : y

Represent as fraction

⅜ = 24/y

Multiply both sides by y

⅜y = 24

Make y the subject

y = 24 * 8/3

y = 64

Hence:

64 ounces of yellow paints is required for 24 ounces of blue paints
