Answer:

200

Step-by-step explanation:

Multiplying both sides by 100 and dividing both sides by 75,we have x = 150 ×

Answer:

200

Step-by-step explanation:

75/100 of what = 150, so what = 150*100/75 = 200

0.75 x=150

Equivalently

(3/4) x=150

Then after that you would divide both sides by 0.75 or 3/4

150/0.75 or 3.4 = 200

Lily bought 22.17 pounds of grapefruit. The lightest grapefruit weighed 1.3 pounds. The heaviest grapefruit weighed 1.7 pounds.

nalin [4]

Answer:

Approximately 15 grapefruits

Step-by-step explanation:

Average Value

The mean or average of a sample is a number that represents the whole set by the center value of them. The formula to compute the average is

$\displaystyle \bar x=\frac{\sum x_i}{n}$

Where xi is the value of the element i and n is the number of elements in the set

We need to find an estimate of how many grapefruits Lily purchased knowing the heaviest and the lightest weight of the set. We can find the average value by using the two extreme values:

$\displaystyle \bar x=\frac{1.3+1.7}{2}=1.5$

If each grapefruit weighed 1.5 pounds, then we can estimate the 22.17 pounds of them will contain

$22.17/1.5\approx 15\ \text{grapefruits}$

Help me please? :))))

hram777 [196]

Answer:

(C)

Step-by-step explanation:

The least common denominator between a denominator of 10 and 4 is 20, so to make the denominators of both fractions equal to 20 you have to multiply the first fraction by 2/2 and the second fraction by 5/5.

Hope this helps :)

maddy wants to rent a faster scooter. it costs 10.00, plus 4.25/h she has 27.00 how many hours can maddy rent the faster scooter

Gemiola [76]

Since the scooter costs $10, we can subtract $10 from $27.
That leaves us with $17.
The scooter costs $4.25/hr, so:
17/ 4.25 = the hours that Maddy can rent the scooter for.
17/ 4.25 = 4
Maddy can rent the scooter for 4 hours.

on a piece of paper, graph this system of equations. y = - x - 10 y = x^2 - 2x - 3 then determine which answer choice matches th

olasank [31]

Answer:

Option D. No solution

Step-by-step explanation:

We have the equation of a line:

$y = - x - 10$

We find their cut points.

Cut point with the y axis. (x = 0)

$y = -(0) -10\\y = -10$

Cut point with the x axis. (y = 0)

$0 = -x -10\\x = -10$ .

The line cuts to the x-axis at $x = -10$ and cuts the y-axis at $y = -10$

We have a parabola

$y = x ^ 2 - 2x - 3$

We can factor this quadratic equation by looking for 2 numbers that when multiplied give as result -3 and that when adding these numbers as a result -2. These numbers are -3 and 1.

Then the factors are:

$(x-3)(x + 1) = 0$

The zeros are 3 and -1. So the parabola cuts to the x axis at points 3 and -1.

Now we find the cut points with the y axis. (x = 0)

$y = (0-3)(0 + 1)\\y = -3.$

The parabola cuts to the axis y in y = -3.

Now we can graph the line and the parabola. Observe the attached image.

The system has no solution because the line and the parabola never intersect or touch each other. The answer is the option D
