Answer:

Step-by-step explanation:

Wheelbarrows  is 30/3 = 10

Pair of shoes is (18 - 10) /2 = 4 so one shoe is 2

2 Seed bags is 4 - 2 = 2 so one bag is 1

Answer is 1(seed baf) + 10(wheelbarrows X 2(shoe) = 21

Step-by-step explanation:

1/8=0.125

Answer:

14.25

Step-by-step explanation:

95 x 0.85 = 80.75

95-80.75 = 14.25

Answer:

The fourth option, it's the only FUNCTION that is also not exponential

Step-by-step explanation:

Answer:

SA=78.5

Step-by-step explanation:

Find the area to all visible sides. 4*2.5=10, 10*2 (because there is two of these shapes) is 20. 4.5*4=18, 18*2=36. Finally, 4.5*2.5=11.25, 11.25*2=22.5.

20+36+22.5=78.5

Answer:

450

Step-by-step explanation:

Length = l

Breadth = b

l = 15 + b

Perimeter = 90

Perimeter = 2(l + b)

90 = 2(15 + b + b)

90 = 2(15 + 2b)

90 = 30 + 4b

90 - 30 = 4b

60 = 4b

60/4 = b

15 = b

Hence, l = 15 + 15 = 30

Area = l * b

Area = 30 * 15

Area = 450 unit²

Answer:

31°

Step-by-step explanation:

90° - 59° = 31°

31° + 59° = 90°

because ive done math for 17 years

Answer:

he will need 5 cups of yellow paint

Step-by-step explanation:

10÷2=5, and that means he will need 5 cups of yellow paint per one cup of blue paint

[tex]h(x) = 40x - 16x^2\\h(x) = 15\\40x - 16x^2 = 15\\-16x^2 + 40x - 15 = 0\\[/tex]

Using the quadratic formula we get

[tex]x_1 = 0.5\\x_2 = 2.04[/tex]

Therefore the tennis ball is at least 15 feet above the ground from 0.5 seconds to 2.04 seconds

Answer:

6.5 days

Step-by-step explanation:

106 - 80 =26

26/4= 6.5 days

Answer:

for 80cm

1 =4 cm

x=80cm

4 cmx=80 cm

4 cm. 4 cm

x=20 days

Step-by-step explanation:

1 is equal to 4cm

there x is equal to 80cm

cross multiply

then divid though by 4 because it has letter x

and finally you 20 days as your answer.

Answer:

Step-by-step explanation:

Use PEMDAS

First you do the multuplication of

1/6*(-5/3)=-5/18

Next you do the addition

5+(-5/18)= 90/18-5/18= 85/18

Answer: 2000

Step-by-step explanation:

The following can be gotten from the question:

Principal = Unknown

Rate = 6%

Time = 6 years.

Interest = 720

Note that: Interest = PRT / 100

720 = (P × 6 × 6) / 100

720 = 36P / 100

720 × 100 = 36P

72000 = 36P

Principal = 72000 / 36

Principal = 2000

The amount that he borrowed is 2000.

Answer:

The cost of one hosta is $6

Step-by-step explanation:

A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.

Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied.

In this case, the variables are:

If Kim spent $62 on 5 hostas and 4 pots of ivy, t his is represented by the equation: 5*x +4*y= 62

If Danielle spent $144 on 8 hostas and 12 pots of ivy, t his is represented by the equation: 8*x +12*y=144

So, the system of equations to solve is:

[tex]\left \{ {{5*x+4*y=62} \atop {8*x+12*y=144}} \right.[/tex]

One way to solve a system of equations is through the substitution method, which consists of solving or isolating one of the unknowns (for example, x) and substituting its expression in the other equation. In this way, you obtain an equation of the first degree with the other unknown, and. Once solved, you calculate the value of x by substituting the already known value of y.

Isolating y from the first equation:

[tex]y=\frac{62-5*x}{4}[/tex]

and replacing this expression in the second equation you get:

[tex]8*x +12*\frac{62-5*x}{4}=144[/tex]

Solving:

[tex]8*x +\frac{12}{4}*(62-5*x)=144[/tex]

8*x + 3*(62-5*x)=144

8*x + 3*62 - 3*5*x=144

8*x + 186 - 15*x=144

8*x  - 15*x=144 -186

(-7)*x= -42

x= (-42)÷ (-7)

x= 6

The cost of one hosta is $6

Answer:

Yes, he is correct

Step-by-step explanation:

Represent Michael's home with M and his mother's with H

So, we have:

[tex]M = 12\ ft (below)[/tex]

[tex]H = 12\ ft (above)[/tex]

Required

Is Michael correct?

First, we get the numeric values of the given parameters.

Below sea level means negative:

So:

[tex]M = 12\ ft (below)[/tex] will be rewritten as:

[tex]M = -12[/tex]

Above sea level means positive:

So:

[tex]H = 12\ ft (above)[/tex] will be rewritten as:

[tex]H = 12[/tex]

Two numbers [tex]A\ and\ B[/tex] are said to be opposite if [tex]A + B=0[/tex]

For Michael to be correct:

[tex]M + H = 0[/tex]

Substitute values for M and H

[tex]-12 + 12 = 0[/tex]

[tex]0 = 0[/tex]

Hence, Michael is correct

Answer:

A straight line passing through the origin

Step-by-step explanation:

A proportional relationship will have a particular quantity being related to another

For example, the relationship might be inverse or direct

In this case, we can have a straight line graph that passes through the origin

A straight line graph that passes through the origin would show the proportional relationship as it has no slope whatsoever

Answer:

[tex]S = \{(Oatmeal, Coffee),(Eggs, Coffee),(Pancakes,Coffee),[/tex] [tex](Oatmeal, Tea),(Eggs, Tea),(Pancakes,Tea)\}[/tex]

Step-by-step explanation:

Given

[tex]Meal = \{Oatmeal, Eggs, Pancakes\}[/tex]

[tex]Beverage = \{Coffee, Tea\}[/tex]

Required

Determine the sample space

The sample space is a list of combination of 1 meal and 1 beverage.

Because one individual can order only one of the meals and one of the beverages at any one time, then no two orders can be the same

The sample space (S) is as follows:

[tex]S = \{(Oatmeal, Coffee),(Eggs, Coffee),(Pancakes,Coffee),[/tex] [tex](Oatmeal, Tea),(Eggs, Tea),(Pancakes,Tea)\}[/tex]
