Triangle ABC has been dilated from center D.
If the length of segment BC = x, which is the
length of segment
ST?
A. 2x
B. 3x
C. 4x
D. 5x

Answers

Answer 1

Answer:

4x

Step-by-step explanation:

Answer 2

Answer:

A. 2x is correct.

Step-by-step explanation:

Finding the measure of the segment BC and ST by the Distance formula: B (5, 7), C (8, 8), S (1, 11), T (7, 13).

BC = √(8-5)² + (8 - 7)²

BC = √10

ST = √( 7 - 1)² + ( 13 - 11)²

ST = 2√10

Scale Factor = Image/ Pre-image = ST/BC = 2√10/√10 = 2

This means that the image, ST, is twice as large as the pre-image BC.

A project manager has ordered 252 pallets of concrete blocks for a construction project. Casone's trucks can each carry 14 pallets of blocks at a time. The project manager used partial quotients to find the number of delivery trucks to expect. His work is shown at the right. Is his solution correct? Explain

Answers

Answer:

18 trucks of delivery

Step-by-step explanation:

Total pallets of concrete blocks ordered = 252 pallets

If each truck can carry 14pallets, then;

1 truck = 14pallets

To determine the number of delivery truck 252pallets can carry, we can express this as:

x truck = 252pallets

Divide both expressions

1/x = 14/252

Cross multiply

14x = 1×252

14x = 252

x = 252/14

x = 18

Hence the manger should expect 1 18 trucks of delivery

Answer:

y = -25x + 170

Step-by-step explanation:

For the graph equation y = ax + b, we have to find a and b.

Pick two points that are on the grid for best accuracy.

e.g., (2,120) and (6,20)

Then a = (20-120)/(6-2) = -25

b is the y coordinate of the line with the y axis: 170

So the formula is:

y = -25x + 170

Find g(-4) if g(x) = 8x^2 + 4x

Answers

Answer:

Your answer would be -144

The value of the function g(x) = 8x² + 4x at g(-4) is 112.

What is a function?

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

Given, a function g(x) = 8x² + 4x.

Now to obtain the value of g(-4) we'll simply substitute - 4 in place of x.

which is g(-4) = 8(-4)² + 4(-4).

g(-4) = 8×16 - 16.

g(-4) = 128 - 16.

g(-4) = 112.

I need 110g of flour to make something. A 10kg (22lb) bag of four is $12. How much does that 110g cost?

Answers

Answer:

Cost of 110 g bag = $ 0.132

Step-by-step explanation:

As we know ,

1 kg = 1000 g

⇒1000 g = 1 kg

⇒1 g = [tex]\frac{1}{1000} = 0.001[/tex] kg

⇒110 g = 110 (0.001) kg = 0.11 kg

⇒110 g = 0.11 kg

Now,

Cost of 10 kg bag = $12

⇒Cost of 1 kg bag = [tex]\frac{12}{10} = 1.2[/tex]

⇒Cost of 1 kg bag = $ 1.2

⇒Cost of 0.11 kg bag = $ (0.11)(1.2) = $ 0.132

∴ we get

Cost of 110 g bag = $ 0.132

Answers

Answer:

[tex]a_{n}[/tex] = 10n + 26

Step-by-step explanation:

[tex]a_{n} = a_{1} + (n - 1)d[/tex]

In your problem d = 46 - 36 = 10   and [tex]a_{1} = 36[/tex]

So,  [tex]a_{n}[/tex] = 36 + (n - 1)10

You are running the concession stand at a volleyball game, selling hot dogs and cans of pop. Each hot dog costs $1.50 and each soda costs $0.50. At the end of the night you have made exactly $78.50. You know that you have sold exactly 87 items, but cannot remember how many of each. That mean PTA lady will never let you work the concession stand again if you don’t report the correct number of each item sold! How many of each did you sell?

Answers

Answer:

Hot Dogs: 35

Soda: 52

Step-by-step explanation:

35 hot dogs + 52 sodas is 87 items.

35 x $1.50 = $52.50

52 x $0.50 = $26.00

$52.50 + $26.00 = $78.50

What is the probability that the spinner will land on either yellow (y) or green (g)?

A: 1/4.
B: 1/3.
C: 1/2.
D: 2/3.

Answers

Answer:

I believe it's 1/3

I haven't done these in a while, but basically since there is 6 places and it's asking the probability of it landing on 2 out of the 6, so the answer would be 2/6. Since the answer isn't there, just simpify. 2/6 simplified is 1/3. I'm so sorry if wrong, I haven't done this in a while!

It’s B because when you put the 2/6 and reduce it it’s 1/3

Step-by-step explanation:

Let the equation of the line be x = y - 12
