Answer 1

Answer:

52 square feet.

Step-by-step explanation:

length*width=area

Top rectangle = 4ft*5ft = 20sq.ft

Bottom rectangle = 4ft*8ft = 32sq. ft

20+32=52 sq.ft OR (4*5)+(4*8)=52sq.ft

Answers

Answer:

[tex]x>17[/tex]

Step-by-step explanation:

We can treat an inequality just the same as an equality in terms of manipulation!(This doesn't hold for multiplying or dividing by negative numbers, but it holds for all addition).

So, we can add [tex]7[/tex] to both sides of the inequality to get [tex]x-7+7>10+7[/tex].

We can simplify [tex]-7+7[/tex] into [tex]0[/tex], and [tex]10+7[/tex] into [tex]17[/tex].

So, the answer is [tex]\boxed{x>17}[/tex] and we're done!

Answer: 62

Step-by-step explanation: you set up the equation by making the two sums equal eachother. 2x+6=130. then you solve, subtract six from both sides, then you have 2x=124. divide both sides by 2 to get the sum of x. you get x=62

Please provide an explanation to your answer, thank you.

Answers

Answer:

50°

Step-by-step explanation:

According to the vertical angle theorem, two opposite vertical angles formed when two lines intersect each other are always equal (congruent) to each other.

This would mean CBD is equal to ABE which means ABE would be 50°.

Answer:

x=27

Step-by-step explanation:

Aight so the angle of line AB equals 180 degrees. You have 36 degrees plus the right angle (90 degrees) which gets you 126 degrees. Subtract 126 from 180 and you get 54, the remaining value. So if 2x=54, then divide both sides by 2 to get x=27. that should be it

2 (f - 2) = 3 (2f + 5) -8

Answers

answer:

f = -2.75


steps:-

2(f - 2) = 3 (2f + 5) 8


2f - 4 = 6f + 15 - 8


2f - 6f = 15 - 8 + 4


-4f = 15 - 8 + 4


-4f = 11


f = 11 ÷ ( - 4)


f = -2.75


Answer:

f=-2.75

Step-by-step explanation:

2(f-2)=3(2f+5)-8

2f-4=6f+15-8

2f-6f=7+4

-4f=11

f=-11÷4

=-11/4=-2/3/4=-2.75

Answers

Given equation of the line ,

[tex]\implies 4x - 5y +(-1) = 0 [/tex]

Simplify ,

[tex]\implies 4x - 5y - 1 = 0 [/tex]

Transpose terms to RHS ,

[tex]\implies 5y = 4x - 1 [/tex]

Divide both sides by 5 ,

[tex]\implies \boxed{ y =\dfrac{4}{5}x -\dfrac{1}{5}}[/tex]

Now we know the slope intercept form of the line as [tex] y = mx + c [/tex] we have ,

[tex] m =\dfrac{4}{5}[/tex]

As we know that the slope of all parallel lines are same . Henceforth ,

I NEED THE RIGHT ANSWER ASAP NO LINKS!!!

Answers

Answer:

the answer is 21.8

Substitute the value of the variable into the equation and simplify.

If x is 1.9 then the equation turns into: 2(1.9+9) so

1.9+9 = 10.9. Then since it was parentheses it will go back to: 2(10.9). If any number is in parentheses and doesn’t have a plus or minus sign in-front of it, then you multiply, So 2 times 10.9= 21.8.

Thus, If x= 1.9, Then 2(x+9)= 21.8.

Answers

Answer:

1) 62.5

2) 50

3) 75

4) 100

Step-by-step explanation:

1)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After [tex]25*4=100[/tex] days, there will be [tex](1/2)^{4}=1/2^{4}=1/16[/tex] of it left.

So, [tex]1000/16=\boxed{62.5}[/tex].

2)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After [tex]25*3=75[/tex] days, there will be [tex](1/2)^{3}=1/2^{3}=1/8[/tex] of it left.

So, [tex]400/8=\boxed{50}[/tex]

3)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After [tex]25*2=50[/tex] days, there will be [tex](1/2)^2=1/2^{2}=1/4[/tex] of it left.

So, [tex]300/4=\boxed{75}[/tex].

4)

The only answer left is [tex]\boxed{100}[/tex] grams. You can solve it the same way you solved the previous steps.

What is the length of DE
A. 18
B. 12
C. 10
D. 22

Answers

Answer:

the length of DE is A) 18

Step-by-step explanation:

these triangles are similar so you need to create a proportion!

since sides DF and FE are the same, it means that AC and CB are the same!

now we have to find the hypotenuse for DE, which is X

- set up a proportion!

side AC/side AB = side DF/side DE ----> 15/27 = 10/x

- butterfly multiply to get 15x = 270

- divide both sides by 15 to isolate x

now you get --------> x = 18!

One week, Sharon worked 18 hours as a lifeguard and 12 hours at a concession stand and earned $228. The next week, she earned $254 for 24 hours as a lifeguard and 8 hours at the concession stand. How much per hour does she get paid for each job?

Answers

Answer:

She is paid $6.25.hour at the concession and $8.50 as a lifeguard.

Step-by-step explanation:

We know:

18 hours as a lifeguard

12 hours at concession

Total earned = $228

18L + 12C = 228

Then:

24 hours as a lifeguard

8 hours at concession

Total earned = $254

24L + 8C = 254

Move one equation around to get one variable by itself: in this case we can solve for L:

18L + 12C = 228

18L = 228 - 12C

L = (228/18) - (12/18)C

Plug in for L:

24((228/18) - (12/18)C) + 8C = 254

Solve for C:

C = 6.25

Now that we know C, plug in value for C and solve for L:

18L + 12(6.25) = 228

L = 8.5

So she is paid $6.25.hour at the concession and $8.50 as a lifeguard.
