Answer:

x² + 9x + 20 = 0

Step-by-step explanation:

Given a solution x = - a for a quadratic equation then (x + a) is a factor

Here x = - 5 and x = - 4 , then corresponding factors are

(x + 5) and (x + 4)

The quadratic equation is then the product of its factors, that is

(x + 5)(x + 4) = 0 ← expand using FOIL

x² + 9x + 20 = 0

Answer:

maximum score =75

minimum=0

Step-by-step explanation:

The graph showing the relationship between time and the gallons of water pumped by the large hose is given below.

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Given that,

Roderick can water his lawn with a small hose or a large hose.

The small hose pumps 15 gallons of water per minute.

So the slope of the graph is 15.

If the amount of water pumped by small hose is represented by y, and the time taken is represented by x,

y = 15x

The large hose pumps water at twice the rate of the small hose, that is 30 gallons per minute.

So the slope is 30.

If the amount of water pumped by large hose is represented by y', and the time taken is represented by x',

y' = 30x

So the points in the graph are, (0, 0), (1, 30), (2, 60),.....

Hence the graph is drawn below.

Answer:

14

Step-by-step explanation:

to find area, use the equation A=ab/2

a and b are the sides given. a=7, b=4

next, plug into equation

A=7×4/2

A=14

Answer:  C

Step-by-step explanation:

To find the perimeter of a rectangle , you need to use the formula  

P = 2l + 2w   where   P is the perimeter, l is the length, w is the width.

Input the dimensions, for each rectangle and solve for the P

P = 2(3) + 2(9)

P = 6 + 18

P = 24  

P = 2(5) + 2(11)

P = 10 + 22

P = 32

The smaller rectangle has a perimeter of 24 and the large rectangle has a perimeter of 32

The ratio will be    32 : 24  which breaks down to  4: 3

Answer: A

Step-by-step explanation:

Answer:

A

Just do it Step By Step

Yes. The first step is to set up the equations so that one unknown cancels out: here, the z's will cancel out:

5z+4y=-14

3z+6y=-6

-15z-12y=42

15z+30y=-30

8y=12

y=1.5

3z+6y=-6

3z+6(1.5)=-5-9

z=-14/3

Answer:

mode = 1

median = 2

mean = 3

Step-by-step explanation:

Here in this question, we want to calculate the given measures of central tendencies.

1. Mode

The mode refers to the number that has the highest frequency. The number here is the first number which is 1.

2. Median

This refers to the middle number after the numbers have been arranged in the descending or ascending order. Looking at the numbers, we have the middle number at the 8th term. The number at the 8th term is the number 2

3. Mean

The mean is the average of the numbers. It is calculated by summing up the numbers and dividing by the count of the numbers.

The sum of the numbers is;

1(7) + 2(3) + 3(1) + 5(2) + 8(1) + 11(1) = 45

The count of the numbers is 15

The mean is thus;

45/15 = 3

Answer:

$478

Step-by-step explanation:

After 20 years, William will have a total of $3,513.94

After 20 years, Nolan will have a total of $3,991.93

Difference = $478

William:

2300[1 + (.02125 ÷ 4)]^4 · 20

2300 · (1 + .0053125)^80

2300(1.5278)

$3,513.94

Nolan:

2300[1 + (.0275 ÷ 12)]^12 · 20

2300 · (1 + .0023)^240

2300(1.7356)

$3,991.93

After 20 years, $478 more money would Nolan have in his account than William, to the nearest dollar.

Compound interest is when you earn interest on both the money you've saved and the interest you earn.

Formula:

A = P(1 + {r}/{n})^{n.t}

here, we have,

After 20 years, William will have a total of $3,513.94

After 20 years, Nolan will have a total of $3,991.93

Difference = $478

William:

2300[1 + (.02125 ÷ 4)]^4 · 20

=2300 · (1 + .0053125)^80

=2300(1.5278)

=$3,513.94

Nolan:

2300[1 + (.0275 ÷ 12)]^12 · 20

=2300 · (1 + .0023)^240

=2300(1.7356)

=$3,991.93

Hence, After 20 years, $478 more money would Nolan have in his account than William, to the nearest dollar.

[tex]= \color{plum}\tt(C) 7 \frac{2}{4} [/tex]

Quantity of water she needs [tex] = \tt \frac{3}{4} \: cup [/tex]

Number of servings she needs = 10

Number of cups of water she will need :

[tex] = \tt \frac{3}{4} \: \times 10[/tex]

[tex] = \tt\frac{30}{4} [/tex]

[tex] =\tt 7\frac{2}{4} \: cups[/tex]

Thus, she needs [tex] \tt 7\frac{2}{4} \: cups [/tex] of water.

Therefore, the correct option is [tex]\color{plum}\tt(C) 7 \frac{2}{4} [/tex]
