what is [70+(-30)]+[2+(-9)]+[0.3+(-0.1)]
Answer:
33.2
Step-by-step explanation:
When you add the left side of the equation, you get 33.2 because 70-30 is 40, 40+2 is 42, 42-9 is 33, 33+0.3 is 33.03, 33.3-0.1 is 33.2.
When you add the right side of the equation, you get 33.2, because they are the same problem but on side has brackets.

A pizza has a radius of 7 inches. If it is cut into 6 equal slices, what is the area of each slice?
14.66 square inches
25.66 square inches
7.33 square inches
49 square inches
Answer:25.66 in^2/slice. Except for mine. It is 123.34 in^2.
Step-by-step explanation:
Area = pi*r^2
Area = 153.94 in^2
(153.94 in^2)/6 = 25.66 in^2

how to make h the subject in
m= r - h + 4d
9514 1404 393
Answer:
h = r +4d -m
Step-by-step explanation:
There are a couple of ways to go about this:
1) Solve it the way you would any 2-step linear equation.
Step 1:
Identify the terms that do not involve h on the side of the equation that has the h-term. Subtract those terms from both sides of the equation.
m -r -4d = -h
Step 2:
If the coefficient of h is not 1, divide both sides of the equation by that coefficient.
(m -r -4d)/(-1) = (-h)/(-1)
-m +r +4d = h
I like to have the leading coefficient be positive, so I might write this as ...
h = 4d +r -m
__
2) The only h term has a -1 coefficient, so it can be given a coefficient of +1 by adding h to both sides of the equation.
h +m = r +4d
There is an unwanted m term with the h term, so subtract that from both sides of the equation.
h = r +4d -m
Answer:
h = 4d -m + r
Step-by-step explanation:
m = r-h +4d
h = 4d -m + r
we know when the real root is r = h-4d
the m+h = r+4d is step 1
then simply h-m = 4d-m + r is step 2
then h = 4d -m + r

0.15 × 120 = 18
Marty says he would rather have –$5 than $0. Do you agree with Marty? Explain.
Answer:
No I don't agree with Marty because when or if I get more money I have to give it to the bank so lets say I earned 15 dollars I would have to give five to the bank because I owe the them but if Ii have 0 dollars I don't owe the bank money I get all the 15 dollars.
Step-by-step explanation:
Answer/Step-by-step explanation:
I disagree with Marty because If Marty would have -$5 it would mean he owns that person $5. If you don't have money you don't owe anything. If Marty would have -$5 it would mean he owns that person $5. If you don't have money you don't owe anything.

x=?
y=?
Answer:
x = 4 , y = 2
Step-by-step explanation:
Using the sine / tangent ratios in the right triangle and the exact values
sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] and tan60° = [tex]\sqrt{3}[/tex] , then
sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{2\sqrt{3} }{x}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
x [tex]\sqrt{3}[/tex] = 4[tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )
x = 4
and
tan60° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{2\sqrt{3} }{y}[/tex] = [tex]\sqrt{3}[/tex] ( multiply both sides by y )
y [tex]\sqrt{3}[/tex] = 2[tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )
y = 2

[50 pts] Zeke is a cook at Maxine’s Café after school and earns $12.75 per hour. Zeke worked a lot hours this week and charged $17.90 in meals. After paying for meals, Zeke’s earnings were less than $240. Which inequalities can be used to find h, the maximum number of hours that Zeke could have worked this week? (choose 2)
A 240 > 12.75h + 17.90
B 240 > 12.75h – 17.90
C 12.75h – 17.90 < 240
D 12.75h – 17.90 < 240
E 17.90 – 12.75h < 240
Answer:
240 > 12.75h – 17.9012.75h – 17.90 < 240Step-by-step explanation:
Zeke's earnings are:
12.75h - 17.90This amount is less than 240.
This can be shown as:
12.75h - 17.90 < 240 or240 > 12.75h - 17.90The matching choices are B, C and D (note C and D are given same, must be a typo)
Answer:
C 12.75h – 17.90 < 240

Answer:
72π (in terms of pi)
Step-by-step explanation:
V = π·r²·h
Plug in the values.
V = π·3²·8
Solve.
V = 72π
To leave an equation in terms of pi, just square, multiply, and leave pi at the end.
3² = 9·8 = 72

The width of a rectangle measures (26 – 8c) centimeters, and its length measures
(106 + 6c) centimeters. Which expression represents the perimeter, in centimeters,
of the rectangle?
Answer:
first one is correct
Step-by-step explanation:
length of a rectangle = 2b - 8c
breadth of a rectangle = 10b + 6c
now , formula to calculate the perimeter of rectangle is
p = 2 (l + w)
no substitute the value of l(length) and w(width)
p = 2{(2b - 8c) + (10b + 6c)}
p = 2(2b - 8c + 10b + 6c)
p = 2(12b - 2c)
p = 24b - 4c
Tara can type 180 words in 4 minutes at this rate how many words can she type in 10 minutes
Answer:
450 words at a rate of 45 word per minute
Step-by-step explanation:
180 divided by 4 equals 45
times 10 equals 450
Answer:
450 words in 10 minutes
Step-by-step explanation:
To set this up you need to put it like this:
[tex]\frac{180}{4} =\frac{x}{10}[/tex]
From here, you need to cross multiply, which will get you to: 180(10) = 4x
Multiply 180 and 10: 1,800
The equation will now be: 1,800 = 4x
Now, divide both sides by 4: 450 = x
