Mary called a plumber to fix her leaky faucet. The plumber charged a $50 service fee and $20 per hour. Mary owed the plumber $95. Write an equation to find the number of hour, h, that the plumber worked. ​

Answer:

745 k/hr

Step-by-step explanation:

mathematically, 1 day = 24 hours

1670 days = 1670 * 24 = 40,080 hours

The speed is thus;

(29,870,000)/40,080 = 745.259

= 745 km/h

Answer:

Step-by-step explanation: Am not sure if this is the answer you guys are looking for but my in 9th grade and this is how my math teacher taught me how to do it.

one chocolate cake=?=x

one lemon cake=?=y

$270 spent

need to buy total of 18 cakes

1-chocolate cake =$7

lemon cake = $5

cakes 18=x+y

money $110=$7x+$5y

When i graphed it on the demos calculator i got (10,8).

So 10= the number of chocolate cake brought and 4= the number of lemon cake brought

Step-by-step explauuuuuuuuuuu

The required number of plants from the function is 509 when there are 27 rows.

Given that,

The function g(x) = 18x+23 represents the total number of plants at the gardening store if there are x rows of plants in the field. What is the value of g(27) is to be determined.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
Number of plants,
g(x) = 18x+23
Since the number of rows is 27
Now, the number of plants,
g(27) = 27 * 18 + 23
g(27) = 486 + 23
g(27) = 509

Thus, The required number of plants from the function is 509 when there are 27 rows.

Answer:

1582480848 miles

Step-by-step explanation:

The maximum distance is another vertex of the major axis

1,636,484,848 miles - 54,004,000 miles = 1582480848 miles

Based on the calculations, the maximum distance from the Comet to the Sun is equal to 1,582,480,848 miles.

In this scenario, the elliptical orbit of the Comet with respect to the Sun at one focus and a major axis is equal to 1,636,484,848 miles. Also, the closest it came to the Sun is 54,004,000 miles.

Thus, we would divide the length of the major axis by the distance between the Comet and the Sun as follows:

Maximum distance = 1,636,484,848/54,004,000

Maximum distance = 1,582,480,848 miles.

Step-by-step explanation:

Answer:

£694.575

Step-by-step explanation:

Using the formula for calculating the compound interest expressed as;

A = P(1+r)^t

P is the principal = £600

r is the rate = 5% = 0.05

t is the time = 3 years

Substitute into the formula;

A = 600(1+0.05)^3

A = 600(1.05)^3

A = 600(1.157625)

A = 694.575

hence the amount in the account after 3 years is £694.575

Answer:

10 inches

Step-by-step explanation:

Area is qual to length times width.

A = lw

Rearrange this to find width.

w = A/l

Now plug in your known numbers and simplify.

w = 40/4

w = 10

Answer:

Whoa!! Dat is waaay too long

Answer:

turn the decimal into a whole number by multiplying by 10, 100 (what you do to one number you must do to the other)

multiply both by 10 it then becomes

540/75 = 7.2

it's easier to divide whole numbers and is the same answer as 54/7.5

Answer:

y = 1/4x -2

Slope intercept from is y = mx + b

m is the slope (rise/run) and this one is one over four.

The y-intercept is b and this line crosses the y-axis at -2.

Answer:

x = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Given 2 intersecting chords, then the product of the parts of one chord is equal to the product of the parts of the other chord, that is

18x = 9 × 3 = 27 ( divide both sides by 18 )

x = [tex]\frac{27}{18}[/tex] = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

triangle with 2 sides of equal lengths= isoceles

triangle with 3 sides of equal lengths= equilateral

Answer:

if the two sides are congruent, then it's an isosceles triangle.

all angles congruent and it's an equilateral.

all angles unequal and it's a scalene.

if all the angle measures are less than 90 degrees, then it's acute, but more than 90 degrees would be obtuse.

Answer:

3.66 cm

Step-by-step explanation:

r = Radius of cylinder

h = Height of the cylinder = 11 cm

A = Total surface area of the cylinder = [tex]337\ \text{cm}^2[/tex]

Total surface area of a cylinder is given by

[tex]A=2\pi r^2+2\pi rh\\\Rightarrow A=2\pi r(r+h)\\\Rightarrow \dfrac{A}{2\pi}=r^2+rh\\\Rightarrow r^2+rh-\dfrac{A}{2\pi}=0\\\Rightarrow r^2+11r-\dfrac{337}{2\pi}=0\\\Rightarrow r^2+11r-53.64=0\\\Rightarrow 100r^2+1100r-5364=0\\\Rightarrow r=\dfrac{-1100\pm \sqrt{1100^2-4\times 100\left(-5364\right)}}{2\times 100}\\\Rightarrow r=3.66,-14.65[/tex]

So, the radius of the circular top is 3.66 cm.

Answer: 2329 cups

Step-by-step explanation:

Make an equation and you will have c (total number of cups at the end)=2000-125-127+1719-356-782+0= 2329. So the total number of cups at the end of the week is 2329. Hope this helps!

Answer:

We know that:

Mary has 5/7 of the red paint tube

And she also has 4/7 of the blue paint tube.

How much paint does she have in total?

Well, we only need to add these fractions.

5/7 + 4/7 = 9/7

We can rewrite the 9 as 7 + 2, then we get:

9/7 = (7 + 2)/7 = 7/7 + 2/7 = 1 + 2/7

This means that, in total, she has a complete tube and two sevents of other.
