Hi there!

This is super easy to understand, so let me help you out a little, since it looks like you don't know how to figure this out. :)

8 + (n - 1) 6

Remember PEMDAS! It's your best friend when it comes to math.

So, we see what is in the parenthesis first. n - 1 is in the parenthesis. Now, since we know already that n = 10, we can replace that n with the new known value.

Doing what is in the parenthesis now, 10 - 1 = 9. Set the 9 aside.

Now, a number on the outside of a set of parenthesis means to multiply. In this case, the 6 is outside of the parenthesis.

So, 9 × 6 = 54, right?

Finally, we can add the remaining 8 to the 54.

54 + 8 = 62.

Your final answer? 62!

Hope this helps!

Send me a message if you need anymore help with anything! :D

Answer:

Alix does. See below.

Step-by-step explanation:

Givens

Jenny

b1 = 90 cm
b2 = 80 cm
height = 23 cm

Alex

b1 = 90 cm
b2 = 70 cm
height = 27 cm

Formula

For both territories the answer is based on the formula

Area = (b1 + b2)*h/2

Solution

Jenny

Area = (90 + 80)23/2
Area = 170 * 23 / 2
Area = 85 * 23
Area = 1955 units.

Alex

Area = (70 + 90)*27/2
Area = 160*27 / 2
Area = 80* 27
Area = 2160

Alix does by 205 cm

a small plane lands at a point 324 miles east and 92 miles north of the point at which it took off. Find the distance the plane

Setler79 [48]

Answer: 336.80 miles, $15.85^{\circ}$ North of east

Step-by-step explanation:

Given

Plane lands at a point 324 miles east and 92 miles north

Distance is given by using Pythagoras theorem

$\Rightarrow d=\sqrt{324^2+92^2}\\\\\Rightarrow d=\sqrt{113,440}\\\\\Rightarrow d=336.80\ \text{miles}$

Direction is given by using figure i.e.

$\Rightarrow \tan \theta=\dfrac{92}{324}\\\\\Rightarrow \tan \theta=0.2839\\\\\Rightarrow \theta=15.85^{\circ}$

Direction is $15.85^{\circ}$ North of east

Can y'all help me step by step with number 5

aev [14]

If the wall with 4 ft. of storage area can fit 6 sections of plant and the wall with 7 ft. Can fit 5, that means each section is 3 ft. because 7-4=3, so that extra section on the wall with 4 ft. You do this because there is one extra section on the wall with four. Knowing this, the wall with 7 ft. Would be the 7 ft. + 5 sections of 3 ft. So 7+(5x3) = 22. On the wall with 4 ft., do the same,
4+(6x3) =22. Since they are equal and the walls are supposed to be equal, we can confirm this is the right answer

Answer:

Equation: 7+15.50x=100

People= 6

Step-by-step explanation:

7+15.50x=100

-7 = -7

15.50x = 93

divide by 15.50= 6

15.50 times 6 = 93
