a^4*a^4=a^(4+4) , b^1*b^1=b^(1+1)

Answer:

the weight of 24 bricks is :

[tex]124\frac{4}{5}[/tex]

Step-by-step explanation:

[tex]26\frac{1}{4} =26+\frac{1}{4} =\frac{26\times 4}{4} +\frac{1}{4} =\frac{105}{4}[/tex]

It is clear that there is a proportional relationship between the number of bricks and their weights then :

[tex]\frac{26\frac{1}{4} }{5} =\frac{x}{24} \Longrightarrow \frac{\left( \frac{105}{4} \right) }{5} =\frac{x}{24} \Longrightarrow \frac{26}{5} =\frac{x}{24}[/tex]

[tex]\Longrightarrow x=\frac{26\times 24}{5} =\frac{624}{5} =124\frac{4}{5}[/tex]

Answer:

X = 10

Step-by-step explanation:

Since 2x = 20

we can divide 2 from both sides giving us x = 20/2

Therefore , x = 10 because 20 divided by 2 is 10

Answer:

X= 10

Step-by-step explanation:

2X=20

Then Divide both sides by 2 in order to find the value of X

2X/2=20/2

The area painted red on one of the front wheels on DeMarius’ car will be 80.42 inches².

From the information given, the The front wheels on DeMarius’ car are divided into sectors of equal area and the radius of each wheel is 8 inches. The area will be:

= 2/5 × πr²

= 0.4 × 3.14 × 8²

= 80.42 inches²

The radius, in feet, of a rear wheel on the car will be:

r1(2π) = r2(2π)

8(2π) = r2(8/5)(2π)

16 = r2(8/5)

r = 5/8 × 16

Answer:

67.5 kg

Step-by-step explanation:

To determine the weight of 45 books, we need to determine the weight of one book, using the equation (30 books = 45 kg). This can be done by dividing 30 to both sides of the equation. Therefore,

We obtained the following equation;

Now, multiply both sides by 45 to determine the weight of 45 books.

Therefore, the weight of 45 books is 67.5 kg.

Answer:

[tex]\huge\boxed{\bf{45books = 67.5kg}} [/tex]

Step-by-step explanation:

Given:-

To find:-

Ans:-

30books = 45kg

45books = y kg

Let's find 45 books (y)

[tex]\sf \to \frac{30}{45} = \frac{45}{y}[/tex]

[tex]\sf \to 45*45 = 30*y[/tex]

[tex]\sf \to 2,025 = 30*y[/tex]

Answer(s):

What is the dependent variable of an equation?

The dependent variable of an equation is the variable that is completely isolated on one side.

What is the independent variable of an equation?

The independent variable is the variable that is not isolated. The independent variable can either have a cooeficient or has some operation (+ - × ÷) included on that side of the equation.

Determining the independent and dependent variable

In this equation, we can see that "v" is completely isolated on one side and "t" has a cooeficient of 68. Thus, the dependent variable is "v" and the independent variable is "t".

Answer:

%70

Step-by-step explanation:

percentage can be found by dividing the values than multiplying the values by 100

Formula: (value/totalvalue)100

plug in the formula with what we have;

28/40(100)

→ First step; dividing our value by total value (28/40)

28/40 = 0.7

  → Second step; multiplying our value by 100 (0.7)

0.7 * 100 = 70

Therefore cora got %70 correct on her grammar sheet

Answer:

70% correct

Step-by-step explanation:

The relationship between food purchased and food eaten by dogs can be written as, 162 biscuits ≥ 80 biscuits

The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the components that are multiplied are referred to as the factors.

First, let's calculate the total number of dog biscuits that Jim has bought:

= 6 bags × 27 biscuits per bag

= 162 biscuits

Next, let's calculate how many biscuits the dog will eat in 4 weeks:

= 4 weeks × 5 biscuits per day

= 20 biscuits per week

20 biscuits per week × 4 weeks = 80 biscuits

So, Jim has bought 162 biscuits and his dog will eat 80 biscuits in 4 weeks. This means that Jim has brought enough dog biscuits for his dog for 4 weeks.

162 biscuits ≥ 80 biscuits

Step-by-step explanation:

Slope-Intercept Form: [tex]y=mx+b[/tex]

Start from the Y-axis where [tex]b=-3[/tex] then rise/run to the next point. making that our slope.

Point-intercept form: [tex]y-y_0=m(x-x_0)[/tex]

Solve the slope using the two points.

[tex](0,-3)[/tex] and [tex](2,1)[/tex] plug those values into the formula. Make [tex](x,y)=(0,-3)[/tex] and [tex](x_0,y_0)=(2,1)[/tex]

[tex]-3-1=m(0-2)[/tex]

[tex]-4=m(-2)[/tex]

[tex]m=-2[/tex]

[tex]y-(-3)=-2(x-0)[/tex]

Answer:

Step-by-step explanation:

Adding and subtracting expressions:

a) M + (5x² -2xy) = 6x² +9xy - y²

                      M = 6x² + 9xy - y² - (5x² - 2xy)

Remove the parenthesis by mulplying each term of 5x² - 2xy by (-1) as (-1) is outside the parenthesis

                           = 6x² + 9xy - y² - 5x² + 2xy

Combine ( add or subtract) like terms.

                           = 6x² - 5x² + 9xy + 2xy - y²

                           = x² + 11xy - y²

Hint: Like terms have same variable with same power.

Here, like terms are (i) 6x² and (-5x²)  (ii) 9xy and 2xy

b)               (3xy - 4y²) - N = x² - 7xy + 8y²

                   3xy - 4y²       = (x² - 7xy + 8y²) + N

3xy - 4y² - (x² - 7xy + 8y²) = N

3xy - 4y² - x² + 7xy - 8y² = N

3xy + 7xy -4y² - 8y² -x²   = N

          10xy -12y²  - x²     = N

Answer: N =  10xy - 12y² -x²

Answer:

Brand A is the better deal!

Step-by-step explanation:

Let's start by comparing.

We know brand B has the following cost: 5 ounces = $3.75

10 ounces $7.50 and 16 ounces = $12

Now check the graph.

6 ounces cost $3

12 ounces cost $6

20 ounces cost $10

I don't think we need to look any further but brand A is the better deal!

The Probability of red light is 0.3

P(red) = 0.3

The probability that out of the next eight eastbound cars that arrive randomly at the light, exactly three will be stopped by a red light be 0.25.

P(exactly three get stopped by red light)=0.25

The correct option is (d) P(red)=.3,P(exactly 3 get stopped)=.25

A binomial distribution can be thought of as simply the probability of a SUCCESS or FAILURE outcome in an experiment or survey that is repeated multiple times.

The occurrence,

p= probability of a red light

 =[tex]\frac{15}{15+5+30}[/tex]

 = [tex]\frac{15}{50}[/tex]

 = 0.3

Hence, Probability of getting red light be,

P (red)= 0.3

Now, the Binomial distribution formula,

Probability=( [tex]_r^nC[/tex])[tex]\;p^{r} \;q^{n-r}[/tex]

where, r = number of times for a specific outcome within n trials

[tex]_r^nC[/tex]   = number of combinations

p = probability of success on a single trial

q = probability of failure on a single trial

n = number of trial

According to question,

          = 1- 0.3

          = 0.7

Now using the formula, ( [tex]_r^nC[/tex])[tex]\;p^{r} \;q^{n-r}[/tex]

P( exactly 3  get stopped) = ( [tex]_3^8C[/tex])[tex]\;(0.3)^{3} \;(0.7)^{8-3}[/tex]

                                            = [tex]\frac{8!}{3!(8-3)!}[/tex] [tex](0.027) \; (0.7)^{5}[/tex]

                                           =  [tex]\frac{8!}{3!(5)!}[/tex][tex](0.027) \; (0.16807)[/tex]

                                           = [tex]\frac{8 * 7 * 6 }{3 * 2}[/tex] x 0.027 x 0.16807

                                           = 56 x 0.00453789

                                           = 0.25412184

                                          ≈ 0.25

Hence, Probability of next eight eastbound so that exactly three will stopped by a red light be 0.25.
