Answer:

The area of Triangle K is 160

Step-by-step explanation:

First, the question explains how Triangle K was a scale factor of 4, with Triangle J being the original. To find the dimensions of Triangle K, you multiply Triangle J's measurements by 4:

4 x 4 = 16

5 x 4 = 20

Now we know the dimensions of Triangle K, it's time to find the area;

Formula for finding area of a triangle: (H x B) / 2

16 (Height) multiplied by 20 (Base) is 320.

Now, we divide 320 by 2 to find our answer:

320 divided by 2 is 160.

160 will be your answer.

Find the distance between points A (10,-1) and B (-2,5). Round to the nearest tenth

bija089 [108]

Answer:

<h2>The answer is 13.4 units</h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

$d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\$

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

A (10,-1) and B (-2,5)

The distance is

$|AB| = \sqrt{ ({10 + 2})^{2} + ({ - 1 - 5})^{2} } \\ = \sqrt{ {12}^{2} + ({ - 6})^{2} } \\ = \sqrt{144 + 36} \: \: \: \: \: \: \: \\ = \sqrt{180} \\ = 6 \sqrt{5} \: \: \\ =13.416407$

We have the final answer as

<h3>13.4 units to the nearest tenth</h3>

Hope this helps you

Use the graph or table to write a linear function that relates y to x need help on answering number 6 plz

muminat

Answer: y = 4/-1 x -2

Step-by-step explanation:

Y=mx+b

4 and -1 are the “rise and run” (m) (from one point to the next, you must go up 4 units then left 1 unit)

The y intercept (b) is the point where it is on the y axis but 0 on the x axis, so -2

The ratio of boys to girls is 4 to 3.The team has 35 members.How many are girls?

mr_godi [17]

I like to do it by adding 4 and 3 to get 7. then divide 35 by 7. that would be 5. take 5*4 to get 20 boys and 5*3 to get 15 girls.

Estimate.Then find the product 1,925 ×7 Please show work

Licemer1 [7]

1,925 is close to 2,000

so 2,000 x 7 = 14,000

1,925 x 7 = ?

5 x 7 = 35

20 x 7 = 140

900 x 7 = 6,300

1,000 x 7 = 7,000

so 7,000 + 6,300 + 140 + 35 = 13,475 and 13,475 is close to 14,000 or 13,500 or 13,470.

Hope this helps even though a little confusing! ;D

A company that accepts credit cards is charged $0.02 a transaction in

hjlf

this is money, it would technically be $574.20.

But we have to remember that, for your question, you also have a $0.02 Ah, precentages. Gotta love 'em.

Remember that when you want to find how much to take away from something (When you know the percentage that you need to take off), you have to move the decimal two spots to the left, meaning that 21% becomes .21, 4% becomes 0.04, and 112% becomes 1.12. A good way to remember this is by looking at the two dots on the percentage sign, and relating the two dots to the two spots you need to move the decimal by.

Knowing this we can now move on.

To find out how much to take away from something (E.G: 10% of 50 or 54% of 4300), we first need to move the decimal from our percentage. Once we've done that, we're almost ready. Now, we need to multiply w by x to get y and eventually get z (Where w is the number we need to take away from, x is the percentage after we had moved the decimal, and y is the number we need to subtract from w to get z, which is our number after the precentage has been taken out of it.

So,

w * x = y then w - y = z

580 * 0.01 = 5.8 then 580 - 5.8 = 574.2

But since this is money, remember that this can also be expressed as $574.20

<h2>BUT WAIT!!!!</h2><h3>We can't stop here, because we are trying to figure out how much gets added onto the transaction, not how much the transaction would be taxed if they were removed y.</h3>

Meaning, that the answer is actually 585.82, because 580 * 0.01 = 5.8 then 5.8 + 0.02 = 5.82 then 580 + 5.82 = 585.82 ($0.02 being the charge applied to every transaction.)

So, the answer should be $585.82
