This square and a triangle have the same area.

Effectus [21]

Answer:

$18cm$

Step-by-step explanation:

A of triangle =

$\frac{1}{2} bh$

$\frac{1}{2} \times 9 \times 8$

$= 36cm2$

A of square=

$s2$

$36 = s2$

$\sqrt{36cm2} = \sqrt{s2}$

$18cm = s$

You buy halibut at $27 per pound. One portion of seared halibut requires 6 ounces of halibut. How much does the halibut for one

Veronika [31]

Answer:

$10.12

Step-by-step explanation:

first, find the price of one ounce of halibut, by dividing $27 by 16 because there are 16 ounces in a pound, and you get 1.6875. then you multiply that by how many ounces you are buying, which is 6, so your answer is 10.125. round to the nearest cent.

First answer gets brainliest. You do not need to do the graphing or the shading, just pls tell me the inequalities

Aleksandr-060686 [28]

Answer:

y $\geq 20-x$

$y\geq 40-5x$

Step-by-step explanation:

8 nickels = 40 cents

y < 8

x < 35

Let's test

1 nickel and 35 pennies. That doesn't work

4 nickel and 20 pennies. That works. Perhaps we be more precise?

5 nickels and 15 pennies. Right on the point. 20 coins.

Hope this helps :)

Have a nice day!

a train leaves barcelona at 21.28 and takes 10 hours nad 33 minutes to reach paris calculate the time and the distance from barc

Brilliant_brown [7]

Speed = Distance / Time, therefore, Speed = 827km / 10.55 hrs. I got 10.55 hours because I converted the 33 minutes into hours and got 0.55 and added it to the 10 hours which is given. so the answer would be approx. 78.39 km / h. I rounded it to the nearest 2 decimal places.

Given that the triangles are similar, find the value of x. Find the length of NR.<br> S<br> T<br> 40<br> 60<br> R<br> 2x-2<br> 8

andrew-mc [135]

Answer:

NR = 12

Step-by-step explanation:

Given that both trjangles are similar, therefore, it follows that their corresponding side lengths would be proportional to each other. Thus:

$\frac{40}{8} = \frac{60}{2x - 2}$

$5 = \frac{60}{2x - 2}$

Cross multiply

$5(2x - 2) = 60$

$10x - 10 = 60$

$10x = 60 + 10$ (addition property of equality)

$10x = 70$

Divide both sides by 10

x = 7

✔️NR = 2x - 2

Plug in the value of x

NR = 2(7) - 2 = 14 - 2

NR = 12
