Answer:32

Step-by-step explanation:

you add 3 blocks each time

Answer:

about 463 minutes or 7.7 hours

Step-by-step explanation:

area=length*width

4.75ft*3.25ft=15.4375ft^2

Now multiply 15.4375*30 to get 463.125 minutes

Answer:

1/250

Step-by-step explanation:

5^-3 × 2^-1

5^-3 = 1/5^3 = 1/125

2^-1 = 1/2^1 = 1/2

so 5^-3 × 2^-1 means 1/125 × 1/2

= 1/125 × 1/2

= 1/250

Answer:

7.6-5.2n

Step-by-step explanation:

combine like terms so -3.2n-2n = -5.2n

2.6+5=7.6

7.6-5.2n

Answer:

-5.2n + 7.6

Explanation:

2.6 - 3.2n - 2n + 5

= 2.6 - 5.2n + 5

= -5.2n + 7.6

Answer:

  B, C

Step-by-step explanation:

Shelby's total earnings will be the sum of the amount she has earned and the amount she can earn working h hours. That latter amount is 25h, since she makes $25 per hour. She wants that total to be at least $2000.

  75 + 25h ≥ 2000

Dividing by 25 gives ...

  3 +h ≥ 80

subtracting 3, we have ...

  h ≥ 77

These match options B and C of your list.

Step-by-step explanation:

Answer:

WZ = 30

Step-by-step explanation:

set up equation based on WZ = W'Z'

3/4[6x + 10] = 13x - 35

multiply each side of equation by 4 to eliminate fractions:

18x + 30 = 52x - 140

-34x = -170

x = 5

substitute 5 for 'x' in either expression:

13(5) - 35

65 - 35 = 30

Answer:

[tex] \frac{3}{4} (6x + 10) = 13x - 35 \\ [/tex]

Just find the value x

Answer:

-10.7°C

Step-by-step explanation:

The change in the temperature is the difference between the initial  temperature and the final temperature. Let the initial temperature be T1 and the final be T2 then the change in temperature will be

= T2 - T1

Hence

-14.2 = T2 - 3.5

T2 = -14.2 + 3.5

= - 10.7°C

The temperature of the mixture after it cools is -10.7°C

Answer:

y =  60

Step-by-step explanation:

From the  information we get:

x  quantity of 4 dollars  coffee used in the mix

y  quantity of 7 dollars  coffee used in the mix

For the quantity of coffee to be sold a 7 $/pound  ( 90 pounds)

Then  6*90  =  540  $

Therefore

x  +  y  =  90     and

4*x  +  7*y  =  540

A two equations system we solve for x and y

y =  90  -  x

4*x  +  7* ( 90  -  x ) = 540

4*x  +  630 - 7*x  =  540

- 3*x  =  - 90

x = 30 pounds   and

y  =  90  -  30

y  =  60

We should use  60 pounds of the seven $ coffee

Answer:

x=54

Step-by-step explanation:

Answer:

Option A

Step-by-step explanation:

Central angle of the pentagon = [tex]\frac{360}{\text{Number of sides of the regular polygon}}[/tex]

                                                   = [tex]\frac{360}{5}[/tex]

                                                   = 72°

Measure of ∠BAC = 72°

Therefore, measure of ∠BAD = [tex]\frac{72}{2}[/tex]

                                                 = 36°

By sine rule in ΔABD,

sin(36°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

            = [tex]\frac{BD}{AB}[/tex]

            = [tex]\frac{BD}{14}[/tex]

BD = 14(sin36°)

     = 8.23 mm

Similarly, by cosine rule,

cos(36°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]

              = [tex]\frac{AD}{AB}[/tex]

              = [tex]\frac{AD}{14}[/tex]

AD = 14(cos36°)

     = 11.33 mm

Area of ΔABC = 2(Area of ΔABD)

                        = [tex]2(\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                        = AD × BD

                        = 11.33 × 8.23

                        = 93.21 mm²

Since, area of regular pentagon given in the picture = 5(area of ΔABC)

= 5(93.21)

= 466 mm²

Therefore, Option A will be the answer.

Answer:

The Answer is A(6+3x=30)

Step-by-step explanation:

Because there is one 6, and 3 x's then you simplify the problem to be:

6+3x=30

ANSWER: 6+3x=30 (Answer A)

Answer:

B) 3(X+6)=30

Step-by-step explanation:

The correct equation should be 6+3x=30

B is 3X+18=30

The other equations are the same

c) 3x=30-6 (the next step to solving the equation

d) 30=3x+6 (symmetric property)

Answer:

x = 4

Step-by-step explanation:

Using the sine ratio in right Δ JKL and exact value

sin30° = [tex]\frac{1}{2}[/tex] , then

sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{JL}{KL}[/tex] = [tex]\frac{JL}{8\sqrt{2} }[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2JL = 8[tex]\sqrt{2}[/tex] ( divide both sides by 2 )

JL = 4[tex]\sqrt{2}[/tex]

---------------------------------------------------------------

Using the sine ratio in Δ JLM and exact value

sin45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then

sin45° = [tex]\frac{ML}{JL}[/tex] = [tex]\frac{x}{4\sqrt{2} }[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )

x × [tex]\sqrt{2}[/tex] = 4[tex]\sqrt{2}[/tex] ( divide both sides by [tex]\sqrt{2}[/tex] )

x = 4

Answer:

4

Step-by-step explanation:

When explaining my solution I will assume that you know SOH CAH TOA. If you don't leave a comment below and I will explain it

We know the line KL and angle K which is enough to get the rest of the lenghts of this triangle

Using CAH we have

Cos30=x/8sqrt2

solve for x and get

8sqrt2Cos30=x

Put this into your calculator and get that line KJ= 9.7979

With this we can solve for the rest of the trinagle using a^2+b^2=c^2

So we have

9.7979^2+LJ^2=(8sqrt2)^2

Compute what you can and get x by itself to get

LJ^2=32

LJ=sqrt32 which is 5.6568

Now that we know the length of line LJ we can solve the second part of the triange.

Knowing that the hypotonous is equal to 5.6568 and angle j=45 we can use SOH

we have

sin45=x/5.6568

Solve this and get

5.6568sin45=4

x=4
