Step-by-step explanation:

3/4x + 3 = 3/8

3/4x = 3/8 - 3

3/4x = - 21/8

x = -7/2

Answer:

[tex]F = 1.8C +32[/tex]

[tex]F = 86^{\circ}F[/tex]

Step-by-step explanation:

Represent Celsius with C and Fahrenheit with F.

So, we have:

[tex](C_1,F_1) = (100,212)[/tex]

[tex](C_2,F_2) = (0,32)[/tex]

Solving (a): Represent as a linear equation

First, we calculate the slope:

[tex]m = \frac{F_2 - F_1}{C_2 - C_1}[/tex]

This gives:

[tex]m = \frac{32 - 212}{0 - 100}[/tex]

[tex]m = \frac{-180}{- 100}[/tex]

[tex]m = 1.8[/tex]

The linear equation is then calculated using:

[tex]F - F_1 = m(C -C_1)[/tex]

Where

[tex](C_1,F_1) = (100,212)[/tex]

[tex]m = 1.8[/tex]

[tex]F - 212 = 1.8(C -100)[/tex]

[tex]F - 212 = 1.8C -180[/tex]

Make F the subject

[tex]F = 1.8C -180+212[/tex]

[tex]F = 1.8C +32[/tex]

Solving (b): The value of F when C = 30

Substitute 30 for C in [tex]F = 1.8C +32[/tex]

[tex]F = 1.8 * 30 + 32[/tex]

[tex]F = 54 + 32[/tex]

[tex]F = 86[/tex]

Answer:

person above me is wrong

Answer:

Please check explanations

Step-by-step explanation:

When we talk about the slope, we are simply referring to the change in y-value with respect to a change in x-value

From the regression line equation, we can see that the value of the slope is negative

What this means is that as the x value is increasing, the y value is decreasing

This makes sense in the context of the problem because it is expected that the amount of fuel in liters is expected to decrease with an increasing amount of time

Where is the graph?

Step-by-step explanation: How does anyone answer without a graph lol

Answer:

863.5 ft³

Step-by-step explanation:

Given that :

Diameter, d = 10 ft

Height, h = 11 feets

Radius of tank, r = d/ 2 = 10ft / 2 = 5 ft

The volume of a cylinder is calculated using the relation :

Volume = πr²h

Volume = 3.14 * 5^2 * 11

Volume = 3.14 * 25 * 11

Volume = 863.5ft³

Answer:

i beleve they would get an 80% sorry if im wrong

Answer:

the answer is 80%

Step-by-step explanation:

Think of it this way

There is 5 problems wrong out of 25 so    5/25  is the fraction   (right/ number of questions)    

5/25 can be simplified to 1/5     (divide by 5)

1/5  can be transformed to the percentage 20%

NOW BE CAREFUL  20% is what is WRONG so 100-20=80

so 80% is thus the answer

Enjoy :)

Answer:

Step-by-step explanation:

Remark

We have to assume that the die is a cube.

We know that getting a 3, if the die is fair,  is 1 chance out of 6 = 1/6

We don't know how many blues there are on the spinner, but we do know that the number of them is over 20. So that's x/20

Now multiply the left side to get the combined probability. x/20 * 1/6. The result is 10.83/ 100

Solution

(x/20) * (1/6) = 10.83/100

x / 120 = 10.83/100                     Multiply both sides by 120

x = 10.83 * 120 / 100

x = 12.996 which is going to round to 13

The blue spaces = 13

Answer:

176cm

Step-by-step explanation:

Step 1

We find the circumference of the cylinder

The formula for the Circumference = 2πr or πD

π = 22/7

Hence;

22/7 × 7

= 22

Since the strip of paper eight times round a cylindrical pencil of diameter 7mm, the length of the paper is calculated as: 22 × 8

= 176cm

Answer:

c) 160,000

Step-by-step explanation:

Since we know that the population of both city x and city y are equal in 2015, we can use the population growth of population of city x to find the population in 2015:

120,000 x 1.2 = 144,000.

Now, since we know that City Y's population decreased 10% from 2010 to 2015, we can divide the 2015 population of city Y (which is the same as city x - 144,00) by 1 - decrease rate to find city y's population in 2010:

1 - .1 = .9

144,000 / .9 = 160,000

Answer:

84 years

Step-by-step explanation:

Given :

At present :

Let :

daughter's age = x

Woman's age = 2x

21 years ago :

Woman's age = 3 times daughter's age

2x - 21 = 3(x - 21)

2x - 21 = 3x - 63

-21 + 63 = 3x - 2x

42 = x

Daughter's age = 42

Woman's age = 2x = 84

Hence, woman's present age is 42 years
