Answer:
A: 15 + 17h = c B: 4 hours
Step-by-step explanation:
For A you do write the equation by finding your x and your y first
x= $15 fee
y= $17 per hour to clean a house
c= total amount of money charged
For B you can do the problem like this:
You subtract the total amount of money which is $83 by the fixed fee of $15* and then divide your total which is $68 by the amount of money charged per hour which is $17 and you get your answer which is 4 hours.
You can also do your problem like this:
You subtract $83 - $15 to get $68
Then you can multiply $17 per hour by the number of hours that add up to $68 to get your answer.
(No matter what you have to subtract the $83 by the $15)*
Hope that helps you out alot!!!!!

TYSM TYSM What is the surface area of the square pyramid?
I put a picture!
⬇️
Answer:
the surface area is 133cm.
7 x 7 is 49
7 x 6 is 42.
42 divided by 2 is 21.
21 x 4 is 84
So 84 + 49 is 133.
HOW TO DO THIS QUESTION
Answer:
see explanation
Step-by-step explanation:
The dot above the 5 indicates the 5 is repeating , that is
2.7555...
We require 2 equations with the repeating 5 placed after the decimal point.
let x = 2.7555,,, ( multiply both sides by 10 and 100 )
10x = 27.55... → (1)
100x = 275.55... → (2)
Subtract (1) from (2), thus eliminating the repeating 5
90x = 248 ( divide both sides by 90 )
x = [tex]\frac{248}{90}[/tex] = [tex]\frac{124}{45}[/tex]
6 1/2 = 1 1/4 + n. Which statements are correct. Check all that apply.
Answer:
n = 5.25
Step-by-step explanation:
6.5 = 1.25 + n
6.5 - 1.25 = 1.25 - 1.25

6. If the measure of an arc is 68, what is the measure of its central angle?
Answer:
68
Step-by-step explanation:
Measure of arc = Measure of corresponding central angle
Thus, if the measure of an arc = 68, then the measure of its central angle also = 68
The distance between D(-3,5) and E(x, 9) is 15. Find the value(s) of the
missing coordinate.
9514 1404 393
Answer:
x ≈ -17.457 or 11.457
Step-by-step explanation:
The distance formula can help.
d = √((x2 -x1)² +(y2 -y1)²)
Substituting given values, we have ...
15 = √((x -(-3))² +(9 -5)²)
225 = (x +3)² +16 . . . . . . . . square both sides
209 = (x +3)² . . . . . . . . . . . subtract 16
±√209 = x +3 . . . . . . . . . take the square root
-3 ± √209 = x . . . . . . . . subtract 3
x ≈ -17.457 or 11.457

Answer:
y= 4x -3
Step-by-step explanation:
1) add -8x at both members
8x - 2y - 8x = 6 - 8x
-2y = -8x + 6
2) divide both members by -2
y = 4x -3
A CYLINDRICAL FISH TANK
IS 12 INCHES TALL. THE
RADIUS OF THE FISH TANK
IS 5 INCHES. HOW MUCH
WATER DOES IT TAKE TO
FILL THE TANK?
Answer:
942.6in^3
Step-by-step explanation:
Given data
Height= 12 in
Radius= 5 in
The expression for the volume of a cylinder is
V= πr^2h
V= 3.142*5^2*12
V= 3.142*25*12
V= 942.6in^3
Hence the volume of the cylinder is 942.6in^3

Step-by-step explanation:
A grocer wants to sell fiuit in boxes.
He wants to make the boxes from square card 36 inches long and 36 inches wide as shown.
Answer:
Solution given:
For finished box
length[L]=36-4-4=28in
breadth [b]=36-4-4=28in
height[h]=4in
Now
volume of square box=l×b×h=28*28*4=3136in³
1.
the volume of finished box is 3136in³
2.
if we change the 4 inches into different measurement ,its maximum or largest volume is 3136in³.
As volume is constant.
The volume of the box will be 3136 cu. unit and the largest volume the box can be made of is also the same.
What is volume ?The amount of space occupied by a three-dimensional object as measured in cubic units (such as quarts or liters)
The given square after getting folded turns into a box of 28*28*4 inches
The volume of the box can be detrmined by using the formula of volume of the cuboid.
Volume of the cuboid = 28*28*4
=3136 cu.inches
The largest volume that the box can have is 3136 as when increasing the height the length or the width will decrease and so does the volume.

2. Will each number be larger or smaller than the given number? Then fill in the blank.
larger smaller a) 3 m = ________ cm
larger smaller b) 28 cm = _________mm
larger smaller c) 2.4 km = _________m
larger smaller d) 485 mm = _________cm
larger smaller e) 35 cm = ____________m
larger smaller f) 2.4 m = _____________km
larger smaller g) 2495 mm = __________m
1.
a) metres to centimetres :
multiply length by 100
b) metres to millimetres:
multiply length by 1000
c) kilograms to grams:
multiply the mass value by 1000
d) litres to millilitres :

2.
a) 3 m = 3× 100 = 300 cm
b) 28 cm = 28 × 10 = 280 mm
c) 2.4 km = 2.4 × 1000
= 24 × 10^-1 × 10^3
= 24 × 10^2 =2400 m
d) 485 mm =485 / 10
= 485 / 10 ^1
= 485 × 10 ^-1
= 48.5 cm
e) 35 cm = 35 / 100
= 35 /10^2
= 35 × 10 ^ -2
= 0.35 m
f) 2.4 m = 2.4 / 1000
= 24 × 10 ^-1 / 10^3
= 24 × 10^-1 × 10 ^-3
= 24 × 10 ^ -4
= 0.0024 km
g) 2495 mm = 2495 /1000
