The equation of the line that is parallel to y=-0.75x and passes through the point (8,0) is y = -0.75x + 6.

The equation of a line in the form y = mx + b represents a linear equation, where m is the slope of the line and b is the y-intercept. Since we are looking for a line parallel to y = -0.75x, we know that the new line will have the same slope. So, the equation of the new line is y = -0.75x + b. To find the value of b, we can substitute the coordinates of the point (8,0) into the equation and solve for b.

0 = -0.75(8) + b

0 = -6 + b

b = 6

Therefore, the equation of the line that is parallel to y = -0.75x and passes through the point (8,0) is y = -0.75x + 6.

Step-by-step explanation:

1cm:1000cm

multiply the dimensions by 1000cm

4cm--> 4000cm

3cm--> 3000cm

convert 4000cm and 3000cm to metres by dividing by 100

because 1m=100cm

4000/100=40m

3000/100=30m

40m x 30m= 1200m²

Answer:

178 m

Step-by-step explanation:

The area of a square is the square of one of its sides, so the square root of the area is the length of one of its sides.

√31684 = 178

Since you know the area of a square is lengh times width,

you can do…

length x width= 31684

but since you know that length=width

it is just length squared=31684

so,

length= square root of 31684

at the end length of each side of a square are the the same so, if you know one then you know all of the others,

so,

length of each side in this square is=178 meters

Answer:

It is highly important for all solutions of rational equation to be checked to make sure you get the right answer.

In solving a rational equation, we always clear of fractions. When we clear of fractions we always multiply both sides by a variable quantity. When we multiply both sides of an equation by a variable expression, we may introduce an extraneous solution a zero of that expression we multiplied through by.

Answer:

1/2 or B on edge

Step-by-step explanation:

If one were to simplify the fraction 48 / 192, the result they would get is the fraction 1/4 or One-fourth

When taking a fraction to its simplest form, you divide both the numerator and the denominator by their greatest common factor.

The greatest common factor of both numbers is 48.

The simplest form is therefore:

= (48 ÷ 48) / (192 ÷ 48)

= 1 / 4

In conclusion, the fraction at its simplest form is 1/4.

Answer:

13a. 0.92 miles

13b. C

Step-by-step explanation:

13a. The first ride costs $2.75 more than the second ride.  Each quarter mile after the first quarter mile costs $0.75, so the difference in distance is:

0.75 d = 2.75

d = 3.67

The difference is 3.67 quarter miles, or 0.92 miles.

13b. The total cost is the cost of the first quarter mile plus the cost of the rest of the quarter miles.

Equation is defined as a relation that equates two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given are 49% of students at a school are boys. There are 2610 students at the school.

Assume that there are [x] girls are there. Then, we can write -

x = 2610 - 49% of 2610

x = 2610 - (49/100) x 2610

x = 2610 - 1279

x = 1331

Answer:

The slope is 0 and the y-intercept is -4

Answer:

3.625

Step-by-step explanation:

I check on Google for yeah ;)

Since the average weight of a coconut is 2.22 kg less than a watermelon, its average weight is

[tex]4.61-2.22=2.39[/tex]Let n be the number of coconuts and watermelons. The total weight of n coconuts and n watermelons is

[tex]4.61n+2.39n = 7n[/tex]

If we want this total to be 140, we have

[tex]7n=140 \iff n=\dfrac{140}{7}=20[/tex]

So, you have 20 coconuts and 20 watermelons.

Final answer:

To find the number of coconuts, we can set up an equation using the given information. The average weight of a watermelon is 4.61 kg, and the average weight of a coconut is 2.22 kg less than a watermelon. By setting up the equation x(4.61 + 2.39) = 140 and solving for x, we find that there are 20 coconuts.

Explanation:

To solve this problem, we need to set up equations using the given information. Let's represent the number of coconuts as 'x'. The average weight of a watermelon is 4.61 kg, and the average weight of a coconut is 2.22 kg less than a watermelon, which means it is 4.61 - 2.22 = 2.39 kg. Since the number of coconuts and watermelons is equal, we can write the equation: x(4.61 + 2.39) = 140. Solving this equation, we get 7x = 140, which means x = 140/7 = 20.

Therefore, there are 20 coconuts.

Step-by-step explanation:

Answer:

The solutions of the equation are t = 4(√5 + 1) or 4(√5 - 1).

Step-by-step explanation:

We have to solve the given quadratic equation of single variable t.

The equation is 16 = 2t + 0.25t²

⇒ 0.25t² + 2t - 16 = 0

⇒ 25t² + 200t - 1600 = 0 {Multiplying both sides with 100}

⇒ 25t² + 200t + 400 - 400 - 1600 = 0

⇒ (5t + 20)² - 2000 = 0

⇒ (5t + 20)² - (20√5)² = 0

⇒ (5t + 20 + 20√5)(5t + 20 - 20√5) = 0

So, (5t + 20 + 20√5) = 0 or, (5t + 20 - 20√5) = 0

⇒ (t + 4 + 4√5) = 0 or, (t + 4 - 4√5) = 0

⇒ t = - 4(1 + √5) or, t = 4(√5 - 1) (Answer)

Answer:

D

Step-by-step explanation:

At the maximum height, the value of the vertical velocity Vy equals zero. From the value of the equation, we can get the vertical velocity by its first differential.

Differentiating this, we get -32x + 64

We then equate this value to zero. This yield 32x = 64 and x = 2

We now plug the value of x back into the original expression for height.

-16(2)^2 + 64(2) + 80 = -64 + 128 + 80 = 144 feet

The difference in slopes of [tex]f(x)\ and\ g(x)[/tex] is = 3

We can say slope of [tex]f(x)[/tex] is positive  and 3 more than slope of [tex]g(x)[/tex] while slope of [tex]g(x)[/tex]  is negative.

Difference of y-intercepts of [tex]f(x)\ and\ g(x)[/tex] is = -7

We can say the y-intercept of [tex]g(x)[/tex] is positive and 7 units above [tex]f(x)[/tex] while y-intercept of [tex]f(x)[/tex]  is negative.

Step-by-step explanation:

Given equation:

[tex]f(x) =2x - 2[/tex]

[tex]g(x) =5-x[/tex]

We need to find the difference of slopes and y-intercepts of the given equations.

The standard form of a slope intercept equation of line is given by:

[tex]y=mx+b[/tex]

where [tex]m[/tex] represents slope and [tex]b[/tex] represents y-intercept of line.

Writing the given equations in standard form to find slope and y-intercept.

[tex]f(x) =2x +(-2)[/tex]

Slope = 2 and y-intercept =-2

[tex]g(x) =(-1)x+5[/tex]

Slope = -1 and y-intercept =5

The difference in slopes of [tex]f(x)\ and\ g(x)[/tex] is = [tex]2-(-1)=2+1=3[/tex]

We can say slope of [tex]f(x)[/tex] is positive  and 3 more than slope of [tex]g(x)[/tex] while slope of [tex]g(x)[/tex]  is negative.

Difference of y-intercepts of [tex]f(x)\ and\ g(x)[/tex] is = [tex]-2-5=-7[/tex]

We can say the y-intercept of [tex]g(x)[/tex] is positive and 7 units above [tex]f(x)[/tex] while y-intercept of [tex]f(x)[/tex]  is negative.

Answer: 325 ft

Step-by-step explanation:

6 mushrooms = 650 ft

divide by 2 on both sides

3 mushrooms = 325 ft

5 mushrooms = 6-1 mushrooms

5 mushrooms = 650 - (boost distance for 1 mushroom)

1 mushroom = 650/6 = 108.3 repeating

so 5 mushrooms = 650 - 108.333333333 = 542.66666666

Add the total males together: 13 + 85 = 98,

So the total male need to be 98,

the total adults is given as 200.

The total women would be 200 - 98 = 102

The table with those three totals is table D.

Answer: It's D

Step-by-step explanation:

First, look at the sum of both female and male adults. As it states in the question, they must add up to 200. Therefore, there are 98 males under 6 ft. So, graph that shows 98 females under 6ft is correct. Which is D in this case.
