Find the difference. (−2g+7)−(g+11)

Answer:

2.5 minutes

Step-by-step explanation:

I'm not really sure how to use the equation but this is how you do it:

There are 12 gallons already there and they want to get to 27 so he needs 15 more gallons. We know that it fills up 6 gallons a minute so to fill the 60 gallon pool it will take 10 minutes. 15 is a quarter of 60 so you divide 10 by 4. This gets you 2.5.

The number line which represents all of the solutions for the problem situation is Number line A.

An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.

here, we have,

to solve an inequality:

Volume of the pool = 60-gallons

Water in the pool already = 12 gallons

Water left to fill the pool = 27 gallons

Water flow per minute = 6 gallons

Number of minutes it takes to fill the pool = x

The inequality:

27 ≤ 12 + 6x

subtract 12 from both sides

27 - 12 ≤ 6x

15 ≤ 6x

divide both sides by 6

x ≤ 15/6

x ≤ 2.5 minutes

Therefore, the given inequality has the solution x ≤ 2.5 minutes.

/12     /12

x=.55

Answer:

0.55$

Step-by-step explanation:

Divide $6.60 by the 12 cupcakes

6.6 divided by 12 is 0.55

So each cupcake costs $0.55

Answer:

b=37.5cm

h=15cm

A=281.25

Step-by-step explanation:

The scale factor will represent how many times bigger the base and the height of the triangle are com that of the smaller triangle. So in order to find these transformations, we need to multiply the scale factor of 7.5 by both the base and the height.

b=7.5(5cm)=37.5cm

h=7.5(2cm)=15cm

so now we can find the area of the enlarged triangle by using the formula:

[tex]A_{triangle}=\frac{bh}{2}[/tex]

[tex]A=\frac{(37.5cm)(15cm)}{2}[/tex]

[tex]A=281.25 cm^{2}[/tex]

Answer:

281.25

Step-by-step explanation:

Answer it's 40 all you had to do was add 26 and 14 you get 40 then subtract from 80 then you find your height

Step-by-step explanation:

Answer:

40

Step-by-step explanation:

Add the height and width and you get 40 then take it from 40

A minor arc

Step-by-step explanation:

Answer: Volume of lid = 29.44 cubic cm and surface area = 40.41 cubic cm.

Step-by-step explanation:

Given: For  lid of the spherical shaped bottle,

Diameter = 5 cm

Height = 4.5 cm

Radius = Half of diameter = 2.5 cm

Volume of cone = [tex]\dfrac13\pi r^2 h[/tex]

Volume of lid  [tex]=\dfrac13(3.14)(2.5)^2(4.5)=29.4375\approx29.44\text{ cm}^3[/tex]

Surface area of cone = [tex]\pi r\sqrt{h^2+r^2}[/tex]  [as lide has no base we don't include area of base.]

Surface area of lid = [tex](3.14)(2.5)\sqrt{(2.5)^2+(4.5)^2}= 7.85\sqrt{26.5}\approx40.41\text{ cm}^3[/tex]

Hence, volume of lid = 29.44 cubic cm and surface area = 40.41 cubic cm.

Answer:

Keisha will owe $18444.32 after 9 years

Step-by-step explanation:

Compound Interest

It occurs when the interest is added to the principal rather than paying it in.

It basically means paying interest over interest.

The formula is:

[tex]\displaystyle A=P\left(1+{\frac {r}{n}}\right)^{nt}[/tex]

Where:

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

Keisha borrowed P = $8000 at a rate of r = 9.5% = 0.095 (assumed annual rate) compounded semiannually (twice a year).

If she makes no payments, the amount she owes increases over time. After t = 9 years, we can calculate the amount owed by using the above formula.

Please, note that since there are 2 compounding periods per year, n = 2, thus:

[tex]\displaystyle A=8000\left(1+{\frac {0.095}{2}}\right)^{2\cdot 9}[/tex]

Operating:

[tex]\displaystyle A=8000\left(1+0.0475\right)^{18}[/tex]

[tex]A = 8000\cdot 2.30554[/tex]

A = $18444.32

Keisha will owe $18444.32 after 9 years

Step-by-step explanation:

Answer:

The y intercept is (0, 8). The equation of the function is f(x) = 10x + 8

Step-by-step explanation:

Given that after 1 hour of work, Jack will make 18 dollars and the slope is 10, subtract 10 dollars from 18 dollars to find his set amount, or y-intercept.

18 - 10 = 8 dollars.

Now that we have the m and b values, we can create our equation.

The equation in standard form is f(x) = mx +b, where m = the slope and b = the y-intercept. Plug our values in and the equation will be f(x) = 10x + 8. You can test if this is correct by plugging in x values from the table and seeing if your calculated value correctly corresponds to the given y value in the table.
