The Bernards are trying to determine their babysitter's rates but are to embarrassed to just ask her. They were charged $20 for 2 hours last week, but only $31 for 4 hours this week. What is the formula to determine A(Amount) given t(time in hours)?

Answers

Answer:

A = 5.5t + 9

Step-by-step explanation:

We assume that the relationship between t and A is linear.

We have two points on a line: (2, 20) and (4, 31).

We now find the equation of the line.

A = mt + b

m = (31 - 20)/(4 - 2) = 11/2 = 5.5

20 = 5.5(2) + b

20 = 11 + b

b = 9

A = 5.5t + 9

Bonus Problem 2. A pump fills an empty pool at a rate of 500 cubic meters per hour. If one liter is equivalent to one cubic decimeter and 1 meter is equal to 10 decimeters, how many liters of water are in the pool half an hour after the pump starts?

Guys im begging you this is why i joined brainly :C

I'll mark brainliest I promise

Answers

Answer:

250,000 L

Step-by-step explanation:

we are given the fill rate of 500 m³ per hour , i.e.

in 1 hour ------> 500 m³ would have been added

if the fill rate is constant, then it reasons that in 1/2 hour, we would expect to see only 1/2 volume of water compared to a full hour , hence:

in 1/2 hour ------> 1/2 x 500 m³ = 250m³ would have been added

The question wants the answer in liters, however we have just calculated the volume in m³ above. Hence we need to convert 250m³ into liters

We note that 1 m³

= 1 m x 1 m x 1 m ( we are given that 1 meter is equal to 10 decimeters. substitute this into the equation,)

= 10 dm x 10 dm x 10 dm

= 1000 dm³

therefore 250m³ = 250 m³ x 1000 dm³ per m³= 250,000 dm³

we are further given that:

1 dm³ = 1 L, hence

250,000 dm³ = 250,000L

The cost of a cheese pizza is $9.99 plus $0.35 for each additional topping, t.

Write an inequality that can be used to represent the cost of a pizza that is at most $12.
What is the most number of toppings that a pizza can have and still be at most $12?

Answers

Answer:

Step-by-step explanation:

Solve the equation: 9.99+0.35_< 12

solving it would give you 5.7428571. You can just take the five.

The inequality is 12 ≥ 9.99 + n(0.35) and the most number of toppings are 6.

What is an inequality?

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

Given:

The cost of a cheese pizza is $9.99 plus $0.35 for each additional topping, t.

To write an inequality that can be used to represent the cost of a pizza that is at most $12:

Let n be the extra toppings.

12 ≥ 9.99 + n(0.35)

To find the number of toppings that a pizza can have and still be at most $12:

12 ≥ 9.99 + n(0.35)

n(0.35) ≤ 2.01

n ≤ (2.01) / (0.35)

n ≤ 5.74

n ≤ 6

Therefore, the most number of toppings are 6.

Which angle measures are correct? Select three options. mAngle2 = 125° mAngle3 = 55° mAngle8= 55° mAngle12 = 100° mAngle14 = 100°

Answers

Answer:

m<2 = 125°, m<8 = 55° and m<14 = 100°

Step-by-step explanation:

The question is incomplete.

Lines e and f are parallel. The mAngle9 = 80° and mAngle5 = 55°. Parallel lines e and f are cut by transversal c and d. All angles are described clockwise, from uppercase left. Where lines e and c intersect, the angles are: 1, 2, 4, 3. Where lines f and c intersect, the angles are 5, 6, 8, 7. Where lines e and d intersect, the angles are 9, 10, 12, 11. Where lines f and d intersect, the angles are 13, 14, 16, 15. Which angle measures are correct? Select three options. mAngle2 = 125° mAngle3 = 55° mAngle8= 55° mAngle12 = 100° mAngle14 = 100

Given

m<9 = 80°

m<5 = 55°

From the diagram, m<5+m<6 = 180°

Substitute m<5 = 55° into the formula, to get m<6

55+m<6 = 180

m<6 = 180-55

m<6 = 125°

From the diagram m<6 = m<2 = 125° (corresponding angles)

Also on line e, m<9 = m<12 = 80° (vertically opposite angles)

On line f, m<14+m<16 = 180° and m<12 = m<16 = 80

m<14+80° = 180°

m<14 = 180-80

m<14 = 100°

Also on line f, m<5 = m<8 (vertically opposite angles)

Since m<5 = 55°, m<8 = 55°

Also on line e, m<10 + m<12 = 180

Since m<2 = m<10 = 125° (corresponding angle)

To get m<12,

125+m<12 = 180

m<12 = 180-125

m<12 = 55°

Also m<10 = m<14 = 125° (corresponding angle)

On line e, m<10 = m<11 = 125° (vertically opposite angle)

Also on line e, m<3 = m<11 (corresponding angle)

This shows that m<10 = m<11 = m<3 = 125°

From the above calculation the angle measure that are correct are:

m<2 = 125°, m<8 = 55° and m<14 = 100°

Have a nice day :]

The equation in vertex form is [tex]y = (x + 3)^2 + 1[/tex], and the values of h & k are -3 and 1

What is the vertex form?

The vertex form of an equation is a quadratic equation, written in the form of a parabola

The equation is given as:

[tex]y = x^2 + 6x + 10[/tex]

Write out the constant

[tex]y = (x^2 + 6x) + 10[/tex]

Take the coefficient of x

[tex]k = 6[/tex]

Divide by 2

[tex]k/2 = 3[/tex]

Square the expression

[tex](k/2)^2 = 9[/tex]

So, we have:

[tex]y = (x^2 + 6x + 9 - 9) + 10[/tex]

Rewrite as:

[tex]y = (x^2 + 6x + 9) -9+ 10[/tex]

[tex]y = (x^2 + 6x + 9) + 1[/tex]

Express as a perfect square

[tex]y = (x + 3)^2 + 1[/tex]

Hence, the equation in vertex form is [tex]y = (x + 3)^2 + 1[/tex], and the values of h & k are -3 and 1
