Gabriella is deciding between two landscaping companies for her place of business. Company A charges $30 per hour and a $225 equipment fee. Company B charges $55 per hour and a $125 equipment fee. Let AA represent the amount Company A would charge for tt hours of landscaping, and let BB represent the amount Company B would charge for tt hours of landscaping. Write an equation for each situation, in terms of t,t, and determine the number hours, t,t, that would make the cost of each company the same.

After solving the system of equation we will get

x = 5y/2 +1  

y = 2/5- 2x/5

First equation is written

−2x+5y=−2

Subtract 5y from both sides.

−2x =−2−5y

The equation is in standard form.

−2x=−5y−2

Divide both sides by −2.

-2x/-2 = -5y-2/ -2

Dividing by −2 undoes the multiplication by −2.

x= −5y-2/-2

​Divide  −2−5y  by −2.

so

x= 5y/2 + 1

Now the second equation is

4x−10y=4

Add 4x to both sides

-10y = 4-4x

The equation is in standard form.

Divide both sides by 10

-10y/10= 4-4x/10

Dividing by 10 undoes the multiplication by 10.

y= 4-4x/10

Divide 4-4x by 10.

so

y= 2/5- 2x/5

It would cost $1804.86 to buy concrete for repavement of the driveway if 1 cubic yard of concrete costs $130 .

Given,

Width of driveway = 30 ft = [tex]\frac{30}{3}[/tex] = 10 yard

Length of driveway  = 50ft = [tex]\frac{50}{3}[/tex] = 16.667 yard

As the driveway is repaved by pouring concrete then it's height will increase

Height of driveway = 3 inch = [tex]\frac{3}{36}[/tex] = 0.0833 yard

Volume of driveway = length x breadth x height

Volume of driveway = 10 x 16.667 x 0.0833

Volume of driveway = 13.8836 cubic yard

Cost of 1 cubic yard of concrete = $130.00

then cost of 13.8836 cubic yards of concrete  will be

130.00 x 13.8836 = $1804.86

Thus, the cost of concrete will be $1804.86.

The theorem that proves that the triangles are congruent is the Side-Side-Side (SSS) Congruence Theorem.

The Side-Side-Side (SSS) Congruence Theorem states that if three sides of one triangle are congruent to three sides of another triangle, then the two triangles are congruent. This theorem is useful for proving that two triangles are congruent without having to use angles. The SSS Congruence Theorem is a useful tool for solving geometry problems involving triangles. It can be used to find the unknown side length of a triangle given the lengths of the other two sides, or in more complicated proofs involving multiple triangles. This theorem is also helpful in determining the area of a triangle, as the area is proportional to the product of the lengths of the sides.

The value of the slope is 1 and the value of the y-intercept is 6.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

The slope of the line will be calculated as,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = (10 - 6 ) / ( 4-0)

1.46% probability that fewer than 700 children received their vaccine.

What is probability?

The proportion of favorable cases to all possible cases is used to determine how likely an event is to occur.

Here, we have

95% of children have received their DTaP vaccine p = 0.95

Sample of 750, n = 750

For the approximation, the mean and the standard deviation are given by:

u = np = 750×0.95 = 712.5

σ = [tex]\sqrt{np(1-p)}[/tex]

σ = [tex]\sqrt{750(0.95)(0.05)}[/tex]

σ = 5.97

Using continuity correction, the probability that fewer than 700 children received their vaccine is P(X < 700 - 0.5) = P(X < 699.5), which is the p-value of Z when X = 669.5.

Z = X-u/σ

Z = 669.5 - 712.5/5.97

Z = - 2.18

The p-value of Z = - 2.18 is 0.0146.

Hence, 1.46% probability that fewer than 700 children received their vaccine.

y = 3x – 2 is the equation of the line which passes through 1/3 and 2 5 with slope.

We can use the slope-intercept form of the equation of a line, which is y = mx + b, where m is the slope and b is the y-intercept. We know one point on the line, which is (1/3, 2.5). We can calculate the slope by calculating the rise (change in y) divided by the run (change in x), which is (2.5 - 0) / (1/3 - 0) = 2.5 / 0.33 = 7.5. Therefore, the equation of the line is y = 7.5x + b. To solve for b, we can substitute in our point, (1/3, 2.5) into the equation. We get 2.5 = 7.5(1/3) + b, or 2.5 = 2.5 + b. Therefore, b = 0, and the equation of the line is y = 7.5x + 0, or y = 7.5x.

The linear function that represents the graph of that has the points on the table is: A. .f(x) = 32(3x - 1).

If a point is on a graph of a linear function, its coordinates will make the equation of the linear function true, if plugged into the equation.

Given the table that represents some of the points that are on a linear function graph, use one point, (1, 64), to check which of the functions represents the table.

Substitute x = 1 and .f(x) = 64 into each of the functions given to see which is true:

.f(x) = 32(3x - 1)

64 = 32(3(1) - 1)

64 = 32(3 - 1)

64 = 32(2)

64 = 64 [true]

.f(x) = -32(x - 3)

64 = -32(1 - 3)

64 = 64 [true], however, if we use another set of values, say (5, 448), this function will not be true.

.f(x) = -2(32x - 3)

6 = -2(32(1) - 3)

6 = -2(29)

64 = -58 [not true]

.f(x) = 16(2x - 1)

64 = 16(2(1) - 1)

64 = 16(1)

64 = 16 [not true]
