Answer 1

Answer: It's D, 11.5.

Step-by-step explanation:

To find how many times QRST is bigger that ABCD, we can use the equation

1.4*x=7

or

7/1.4=5.

Since we now know QRST is 5 times bigger, we can multiply 2.3 by 5 to get the length of RS.

2.3*5=11.5

Answer 2
The answer is D 11.5

Expand the expression -12(4c - 3d) using the Distributive Property

Answers

Answer:

-48c - 37d

Step-by-step explanation:

Multiply both numbers by -12.

The expanded form of the expression is -48c+36d

What is Distributive Property?

According to this property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.

Given that, we have to expand the expression -12(4c - 3d) using the Distributive Property,

We know that the rule for distributive property is :

a(b+c) = ab+ac

Therefore,

-12(4c - 3d)

= -12(4c)+12(3c)

= -48c+36d

Hence, the expanded form of the expression is -48c+36d

Answer:

A" (-3, 0)

B" (9, 9)

C" (9, 0)

Step-by-step explanation:

The hint explains how to get the final coordinates.

The original figure ABC has vertices

A (-3, -1)
B (1, 2)

C (1, -1)

There are two separate transformations for this triangle, so let's take it one step at a time

The first transformation is a translation by the vector <2, 1>, This means we get a new figure A'B'C' where we add 2 to each of the x coordinates of the original figure and 1 to the y coordinates of the original figure

For A which is (-3,-1) the transformed coordinate becomes:
A -> A' -> A' (-3 + 2, -1 + 1) => A'(-1, 0)

Similarly

B(1, 2) -> B' is B'(1 + 2, 2 + 1) => B'(3, 3)

C(1, -1) -> C'(1 + 2, -1 + 1) or C'(3, 0)

So the first transformation results in a triangle A'B'C' with the following coordinates:

A'(-1, 0)
B'(3, 3)
C'(3, 0)

The second transformation is a dilation of A'B'C' which results in an expansion or compression of the image depending on the scale factor. Here the scale factor is 3 so the image is expanded by a factor of 3

Dilation simply requires you to multiply both x and y coordinates oof A'B'C' by 3

A' (-2 , 0) -> A"(-1 x 3, 0 x 3) => A"(-3, 0)
B'(3, 3) -> B"(9, 9)
C'(3, 0) -> C"(9, 0)

I have attached two images showing each of the transformations separately to give you a better idea

13 Adults = $210

11 Children = $88

Step-by-step explanation:

x = Adults

y = Children

x + y ≥ 20

$15x + $8 ≤ $300

let's take 13 adults and 11 children

14 + 11  ≥ 20                                   $15*14 + $8*11 ≤ $300

= 25 ≥ 20 ✓                                    =  $210 + $88 ≤ $300

                                                      = $298 ≤ $300 ✓

you are running a ten mile race. The function d(t) = 1-8 |t-40| represents the distance in miles you are from the water stop after t minutes. interpret the intercepts. Explain what each represents in this context

Answers

In this context, the x-intercepts of the graph of the function d(t) = 1 - 8 |t - 40| represent the times at which you are exactly one mile from the water stop. These intercepts occur when d(t) = 0, which means that you are at the water stop. Solving the equation d(t) = 0, we find that the x-intercepts are t = 20 and t = 60.

The y-intercept of the graph represents the distance in miles that you are from the water stop at time t = 0. In this case, the y-intercept is d(0) = 1 - 8|0 - 40| = 1 - 8|-40| = 1 - 8(-40) = 1 + 320 = 321. This means that at time t = 0, you are 321 miles from the water stop.

In summary, the x-intercepts represent the times at which you are exactly one mile from the water stop, and the y-intercept represents the distance in miles that you are from the water stop at time t = 0.

Please help me im struggling and i need to get a 100%

Answers

Answer:

The answer is 29.

Step-by-step explanation:

a straight line is 180 degrees, to subtract 77 from 180 to figure out the red angle. Which is 103 degrees as shown also in red. Now we add 103 and 48 which is 151 degrees. And since all straight lines are 180 degrees, that means that angle p has to be 29. If you add 29 to 151, then you get 180 degrees.

We can picture that there is a straight line (see attached picture).

Since a straight line = 180 degrees, the two angles add up to 180 degrees.

One angle is already 77, so we can subtract 77 from 180, to get the other angle.

Now that we know the other angle=103 degrees, we can imagine another straight line (see 2nd attached image)

Again, since a straight line = 180 degrees, we can subtract the other two angles to find the value of p.

p=29 degrees.

(For some reason it isn’t letting me add two pictures)

I got the 103 degrees by subtracting 77 from 180.
