These is for a test.

Answer:

Step-by-step explanation:

Width = w

Length = double the width = 2*w = 2w

Perimeter of rectangular tray = 60 in

2*(length + width) = 60

          2*( 2w + w) = 60    

                    2*3w = 60

                       6w  = 60

Divide both sides by 6

w = 60/6

w = 10 in

length =2w = 2*10 = 20

length = 20 in

Width = 10 in

Answer:

9x - 5

Step-by-step explanation:

(4x – 6) + (5x + 1).

4x - 6 + 5x +1

9x - 5

Have a good day

Answer:

9x - 5

Step-by-step explanation:

To get the this answer you would combine like terms. 4x and 5x are like terms, so you would combine them and get 9x. -6 and 1 are like terms, so you would combine those and get -5.

Answer:

d = 72

Step-by-step explanation:

d + 13 + 95 = 180

(Angles are supplementary)

d + 108 = 180

d = 180 - 108

d = 72

Answer:

B. Going up the elevator 14 floors

Step-by-step explanation:

Choice A can't be right because you are going below sea level (negative).

Choice C can't be correct either because the word "losing" let's you know that it's negative.

Choice D isn't right because if you are taking $20 from your checking account, it would be a negative number.

Answer:

d = 3

Step-by-step explanation:

(7d+3)/4 = 6

Multiply each side by 4

(7d+3)/4*4 = 6*4

(7d+3) = 24

Subtract 3 from each side

7d+3-3 = 24-3

7d = 21

Divide by 7

7d/7 = 21/7

d = 3

Answer:

(19)(-8i)

Step-by-step explanation:

(2 - 6i)(8 + i)(9 - 3i)

(2 + 8 + 9)(-6i + i - 31)

(19)(-8i)

[tex]\boxed{\sf a_n=\dfrac{a_{n-1}}{10}\times 4,n\gt 1}[/tex]

Lets verify

[tex]\\ \sf\longmapsto a_2=\dfrac{a_1}{10}\times 4[/tex]

[tex]\\ \sf\longmapsto a_2=\dfrac{500}{10}\times 4=50(4)=200[/tex]

And

[tex]\\ \sf\longmapsto a_3=\dfrac{a_2}{10}\times 4[/tex]

[tex]\\ \sf\longmapsto a_3=\dfrac{200}{10}\times 4=20(4)=80[/tex]

And

[tex]\\ \sf\longmapsto a_4=\dfrac{a_3}{10}\times 4[/tex]

[tex]\\ \sf\longmapsto a_4=\dfrac{80}{10}\times 4=8(4)=32[/tex]

Hence verified

Lets predict next term

[tex]\\ \sf\longmapsto a_5=\dfrac{a_4}{10}\times 4[/tex]

[tex]\\ \sf\longmapsto a_5=\dfrac{32}{10}\times 4=3.2\times 4=12.8[/tex]

Answer:

f(- 10) = 74

Step-by-step explanation:

To find f(- 10) , substitute n = - 10 into f(n) , that is

f(- 10) = - 7(- 10) + 4 = 70 + 4 = 74

Hello there!

We are given a function below:

[tex] \displaystyle \large{f(n) = - 7n + 4}[/tex]

To find f(-10), substitute n = -10.

[tex] \displaystyle \large{f( - 10) = - 7( - 10) + 4}[/tex]

Evaluate the f(-10)

[tex] \displaystyle \large{f( - 10) = 70 + 4}[/tex]

Recall

Therefore,

[tex] \displaystyle \large{f( - 10) = 74}[/tex]

f(-10) = 74

Multiply hours per week by hourly pay rate:

20 x $15.75 = $315.00 per week

Multiply by 2 weeks:

$315 x 2 = $630

After 2 weeks paycheck is $630

Answer:

630

Step-by-step explanation:

15.75 x 20 = 315

315 is how much Angel makes in one week

315 x 2 = 630

630 is how much he will make in two weeks

The 2 signifies how many weeks have been worked

Answer:

2.4 cookies

Step-by-step explanation:

Just divide

Step-by-step explanation:

v(x) = y = -3/4x - 1/3

y + 1/3 = -3/4x

x = -4/3 × (y + 1/3)

you see ? we only need to show how we calculate x out of y (instead of the normal direction of y or of x).

and to follow naming standards we now simply switch x and y, so that the inverse function is indeed again a function of x

y = -4/3 × (x + 1/3) = -4x/3 - 4/9

hi <3

1) as the value ahead of the tenths position is a 5, you would round up.

this gives you the answer of 1.6

2) as the value ahead of the hundredths position is a 4, you would round down.

this gives you the answer of 1.55

3) as the value ahead of the thousandths position is an eight, you would round up.

this gives you the answer of 1.555

Answer:

x = 19.6

Step-by-step explanation:

If we need to find the value of x then first we need to

(7x-25) + (3x +9) = 180  (angles at the same side of transversal will be equal to 180 degree )

10x -16 = 180

10x = 180 +16

10x = 196

x = 196/10

x = 19.6

Step-by-step explanation:

Answer: 7.5 (h)

Step-by-step explanation:

Let say

a the outflow of the first pipe

b the outflow of the second pipe

T the volume of the tank.

x the time for filling with the second pipe

two pipes can fill a tank in 3 hours: a*3+b*3=T

One pipe alone can fill the tank in 5 hours : a*5=T

3*b=T -3a ==> 3b= 5a*3a=2a

b=2a/3

b*x=T ==> 2/3*a*x=T ==> 2/3*T/5*x=T ==> 2/15*x=1

x=15/2 = 7.5 (hours)
