Answer:

a = 3.6

Step-by-step explanation:

[tex] \frac{2}{3} (6a + 9) = 20.4 \\ \\ \bigg( \frac{2}{3} . \boxed{6a} \bigg) + \bigg(\boxed{ \frac{2}{3}} . {9} \bigg) = \boxed{ 20.4} \\ \\ (2.2a) + (2.3) = 20.4 \\ \\ 4a + 6 = 20.4 \\ \\ 4a = 20.4 - 6 \\ \\ 4a = 14.4 \\ \\ a = \frac{14.4}{4} \\ \\ a = \boxed{3.6}[/tex]

Answer:

Angles 3 and 8 are consecutive interior angles

Step-by-step explanation:

Here, we want to use the consecutive interior angles theorem to find the supplementary angles

We start by looking at the transversal line

two angles that are directly above each other on the two lines are consecutive interior angles that are supplementary

We have this two as;

Since it is P and Q that are parallel, it is angles 3 and 8 that are consecutive interior angles

Answer:

I'm doing some of these questions now in my math class. I think it's D) 44 sorry if I'm wrong tho

Answer:

Step-by-step explanation:

Since the hypotenuse is 44 and the two sides are equal to FT we can say

2(FT)^2=44^2

FT^2=968

FT=22(2^(1/2))

So C is the correct answer.

Answer: Greetings my dude. The volume of the triangular prism is around 1,138 Centimeters Cubed.

Hope this helps!

Answer:

volume = length * breadth * height

= 16*7*8

=896

Answer:

11: 416

Step-by-step explanation:

so the area of the rectangle is 20*16 and you add the triangle's area which is 96. 320+96=416. I am pretty sure that is the answer. ( Sorry if my drawing is bad) :D

Answer:  4955.30

Step-by-step explanation:

F = P (1+i)^n

F = $4000 (1+.055)^4

F = $4955.2986

Which will be 4955.30

Answer:

A. $4955.30

Step-by-step explanation:

Look at the equation

A(t)= P(1+r)^t

In this equation,

A(t) is your amount after a period of time,

P is the initial balance stated in the question (4000)

r is the rate (must be converted to a decimal) as stated in the question (0.055)

t represents the amount of time that has passed (4 years)

Whenever you plug this into the equation, you get

A(t) = 4000(1.055)^4 and this can be plugged into a calculator to get your answer which will be

4955.29 (round up to .3) and your final answer is A. 4995.30

In order to convert from percent to decimal you just need to move the decimal to the left two places

5.5 becomes 0.055 after the decimal is shifted

Answer:

x = 60

Step-by-step explanation:

So, ever triangle, no matter what shape or size, is always going to equal 180 degrees. You start off by trying to find angle L which is 71. The way you find this is you subratch 109 from 180 which ultimately gives you 71.

180 - 109 = 71

After that you have to add what you already have (49 degrees) with what you just found (71 degrees)

49 + 71 = 120

Now that you have 120, you have to again subtract 180 by 120 to get your answer, 60 degrees. And that's it.

180 - 120 = 60

Answer:

-2

Step-by-step explanation:

Let's solve your equation step-by-step

4x−3=−11

Step 1: Add 3 to both sides

4x−3+3=−11+3

4x=−8

Step 2: Divide both sides by 4

4x

4

=

−8

4

x=−2

Answer:

[tex]4x + ( - 3) = - 11 \\ 4x (- 3) = - 11 \\ 4x = - 11 + 3 \\ 4x = - 8 \\ x = \frac{ - 8}{4} \\ x = - 2[/tex]

you mean the decimal point?

Step-by-step explanation:

You will know when you cross the decimal point when multiplying.

Answer: it would just be like putting a comma normally, just all you have to do is get your new number but then just add both the comma and decimal it shouldn’t effect on where its put! If that’s what your asking!

Step-by-step explanation:

For 7 dozens cookies 3 1/2 cups needed.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

For 3 dozen cookies = 1 1/2 cups = 3/2 cups

For 1 dozen cookies = 3/2 * 1/3 = 1/2 cups needed

So, for 7 dozen cookies = 1/2 * 7

                                       = 3 1/2 cups needed

Hence, for 7 dozens cookies 3 1/2 cups needed.

Answer:

  x > 35

Step-by-step explanation:

The perimeter is twice the sum of length and width. You want x such that ...

  P > 156

  2(x +(x+8)) > 156

  4x +16 > 156 . . . . . simplify

  x +4 > 39 . . . . . . . . divide by 4

  x > 35 . . . . . . . . . . . subtract 4

The perimeter of the frame will be greater than 156 inches for x > 35.
