Answer:

-21.6

Step-by-step explanation:

When a number, like 4 in your equation, is next to parentheses without a sign (ex. plus or minus) it means to multiply. 4(-5.4) is equal to 4x5.14 which is -21.6

Answer:

10^4  ---------------- 10,000

10^-4* 10^2 ------- 1/10^2 = 0.01

10^-4 ---------------- 1/10^4 = 0.0001

10^-4/10^2 -------- 1/10^6 = 0.000001

I'll do the first three problems to get you started

=====================================================

Problem 40

Plug in x = 0 to find the y intercept

x+y = 5

0+y = 5

y = 5 is the y intercept

Plug in y = 0 to find the x intercept

x+y = 5

x+0 = 5

x = 5 is the x intercept

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

=====================================================

Problem 41

Use the same idea here as well

Plug in x = 0 to get

x-y = 5

0-y = 5

-y = 5

y = -5 is the y intercept

Now plug in y = 0 to solve for x

x-y = 5

x-0 = 5

x = 5 is the x intercept

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

=====================================================

Problem 42

Plug in x = 0 and solve for y

3x+4y = 12

3(0)+4y = 12

0+4y = 12

4y = 12

y = 12/4

y = 3 is the y intercept

Plug in y = 0 and solve for x

3x+4y = 12

3x+4(0) = 12

3x+0 = 12

3x = 12

x = 12/3

x = 4 is the x intercept

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

Answer:

x = 4

Step-by-step explanation:

5 multiplied by x and 5 multiplied by -3

5x - 15 = 11 -3(x - 2)

-3 multiplied by x and -3 multiplied by -2

5x - 15 = 11 - 3x + 6

Add 15 to both sides

5x = 26 - 3x + 6

Add 3x to both sides

8x = 26 + 6

Add 26 + 6

8x = 32

Divide 32 by 8

x = 4

Unit rate= 20

words per minute/ 0.3

words per second

Step-by-step explanation:

We could work out the unit rate in 2 ways:

Per Minute or Per second.

First we will start of with per minute:

Rate=Word/minute=100/5=20

Answer:

100 words to 5 minutes

Step-by-step explanation:

Any value that is raised to the power of zero is 1. The value of the expression given in its simplified form is 1

Any value that is raised to the power of zero is 1. Given the expression

(30^2)^0

Simplify

30^2 = 900

Substitute into the original function to have:

(30^2)^0 = 900^0
(30^2)^0 = 1

Hence the value of the expression given in its simplified form is 1

Answer:

There is no fixed domain, meaning it is ongoing

The range is from -1 ≤ x ≤ 3

It is a function

Step-by-step explanation:

Domain refers to the x values. If there was a domain then there would be a dot or a point signalling that there is a fixed domain, however, there are arrows meaning that it will keep going.

The range refers to the y-values. The lowest y-value is -1 and the highest is 3.

It is a function because, when you do the vertical line test, each x-value has its own y-value.

The percentage decrease in length of the board is 25%

From the given statement we can deduce the following:

The change in the length of the board is calculated as:

The percentage decrease in the length is calculated as;

[tex]Percentage \ decrease = \frac{change \ in \ length }{original \ length} \times 100\%\\\\Percentage \ decrease = \frac{6}{24} \times 100\%\\\\Percentage \ decrease = 25\%[/tex]

Answer:

48 inches

Step-by-step explanation:

Remember the Pythagorean theorem, where a and b are legs and c is the hypotenuse

a^2 + b^2 = c^2

a= 20

c = 52

now substitute in the given values

20^2 + b^2 = 52^2

400 + b^2 = 2704

solve using inverse operations

400 + b^2 = 2704

-400            -400

b^2 = 2304

b= sqrt(2304)

b=48

[tex]a= r- d - c[/tex]

Step-by-step explanation:

Converting the equation to solve for a really just means getting a alone on one side of the equation.

[tex]a + c = r - d[/tex]

To get a alone on the left, we can subtract c from both sides:

[tex]a+ c = r -d\\a = r - d - c[/tex] (Since c - c = 0, c will disappear from the left side.)

Answer: [tex]a= r- d - c[/tex]

Answer:

[tex] \longmapsto \: a + c = r - d \\ (a + c) - c = (r - d) - c \\ \boxed{a = r - d - c}✓[/tex]

Answer:

sand = 3450 pounds

3/4 inch stones =6750 pounds

1 inch stones =4800 pounds.

Step-by-step explanation:

The mixture composition is :

45% three-quarter inch stones

32% inch stones and

sand for balance

The percent here is by mass of material used.

Weight of mixture is 15,000 pounds before oil addition.

Use the percent by weight for the two types of stones and calculate real values in pounds

Formula to apply is:

Mass percent = (mass of a material/ total mass of mixture) * 100

For 3/4 inch stones it will be:

[tex]0.45= \frac{x}{15000} *100\\\\0.45=\frac{x}{150} \\0.45*150=x\\x=6750[/tex]

The 3/4 inch stones weigh 6750 pounds

The 1 inch stones will be

[tex]32/100 * 15000 =4800[/tex]

The 1 inch stones weigh = 4800 pounds

Total for the two items : 4800+6750 =11550 pounds

The sand used weighs : 15000 - 11550 = 3450 pounds
