Jodi's car used 12 gallons of gas to travel 456 miles. How many miles did her car travel per gallon of gas?
Answer:
38
Step-by-step explanation:
If there is a constant rate of change in gas prices, all we do is divide 456 by 12 to see the price of each gallon.
Answer:
38
Step-by-step explanation:
456 divided by 12 =38.
Suppose that we have this spinner. What is the probability of landing on 2 after landing on 5?
25%
4%
10%
.2%
There are 5 numbers and only one of each number.
The probability of landing in 5 would be 1/5
The probability of landing in 2 would be 1/5
The probability of landing on 5 then 2 is 1/5 x 1/5 = 1/25 = 0.04 = 4%
answer = 4%

Brad and Angelina can mow their yard together with two lawn mowers in 20 min
. When Brad works alone, it takes him 30 min. How long would it take Angelina to mow the lawn by herself?
It takes Angelina_______ min to mow the lawn by herself.
Answer:
Let A = Angelina's timeLet
B = Brad's time 20
(1/A + 1/B) = 1 B = 30 20(1/A + 1/30) = 11/A + 1/30 = 1/201/A = 1/20 -1/301/A = 1/60A = 60 minutes for Angelina to do the lawn alone

What is the lateral surface area of this right pyramid with a square base?
Answer:
The lateral surface area of a square pyramid is the sum of the areas of the side faces only, whereas the surface area is the lateral area + area of the base. The lateral area of a square pyramid = 2al (or) 2a√[(a 2 /4) + h 2]. To get the surface area, we need to add the area of the base (which is a 2) to each of these formulas.The surface area of a square pyramid = a 2 + 2al (or) a 2 + 2a[(a 2 /4) + h 2]. where, a = Length of the base (square) l = slant height; h = height of the pyramid.

simplify tan(a)/sin (2a)
Answer:
[tex]\frac{sec^2(a)}{2}[/tex]
Combine the terms through trigonometric identity and simplify, this should be your answer(not the actual result of the problem, just the simplified expression).
Answer:
Step-by-step explanation:
The rule is generally to reduce anything that isn't a sin(theta) or cos(theta) down to those two.
Givens
Tan(a) = sin(a) / cos(a)
sin(2a) = 2 sin(a)*cos(a)
Solution
Tan(a)/Sin(2a) = sin(a) / cos(a) // 2 sin(a) * cos(a) / 1 Invert and multiply
Tan(a)/Sin(2a) = sin(a) / cos(a) * 2 sin(a) * cos(a) Cancel and combine
Answer: Tan(a)/sin(2a) = 1 / (2* cos^2(a))

Order the numbers from least to greatest. 0.3, 9/25, 33%, 0.35
Answer:
0.3(least)
0.33
0.35
0.36(greatest)
Step-by-step explanation:
Okay, so first we need to have all of our numbers in the same category of variable. So first, we will convert 9/25 to a decimal.
To do that, we must divide 9 by 25 to get our answer of 0.36.
Now, we will convert the 33% to a decimal by dividing it by 100 to get 0.33
We now have our list, which should be ordered as:
0.3

Answer:
10 mm
Step-by-step explanation:
We know that the formula for a triangle is A= 1/2(b)(h)
Plug in 30mm for the area as shown and 6 for the base= 30=1/2(6)(h)
Solve= 30=3h
Divide each side by 3 to get h by itself. h=10 or b= 10

Apply the formula for the distance between two points:
[tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]d = \sqrt{(10-4)^2+(6-2)^2}[/tex]

Given the regular polygon, what is the measure of each numbered angle?
Answer:
Answer A
Step-by-step explanation:
Approach 1
B, C, and D are wrong because angles 1 and 2 are congruent.
Therefore your answer of both being 60°
Approach 2
Let x = angle 1.
360/x = 6
x = 60°.
Therefore Angle 1 is 60°
An interior angle of a hexagon is 120°
Let y = angle 2.
y is half of 120°
So 120/y = 2
y = 60°

find the value of y
Answer:
[tex]\boxed{\sf{y=-11}}[/tex]Step-by-step explanation:
GIVEN:
To find the value of y, isolate it on one side of the equation.
2y-6-3y+5
Solutions:
First, add by 6 from both sides.
2y-6+6=3y+5+6
Solve.
Add the numbers from left to right.
5+6=11
2y=3y+11
Then, you subtract by 3y from both sides.
2y-3y=3y+11-3y
Solve.
-y=11
Divide by -1 from both sides.
-y/-1=11/-1
Solve.
Divide these numbers goes from left to right.
11/-1=-11
[tex]\Longrightarrow: \boxed{\sf{y=-11}}[/tex]
Therefore, the final answer is y=-11.I hope this helps. Let me know if you have any questions.

Step-by-step explanation:
First find the cordinate by seing were the point lands on the graph
sense it is +10 right the x = 10, and it is 4 below the origin making it a negitive 4, so u get (10,-4)
The graph is measured 2 units per box and sence the sides are parallel to the axies you can count each square by 2, giving you the measuers of 12 units.
Now finally, The area of a triangle is A=1/2bh, we arlready have our base, and we just found our hight, so now we just have to plug it in.

Hank has 50 peso, 200 peso and 500 peso bills in his wallet. He has five less 200 bills as 50 bills, and half as many 500 bills as 200 bills. If he has Php 6250 in all, how many of each denomination does he have?
For an amount of 6250 Peso, Hank have the quantities of the following denominations: 2503 bills of 50 peso, 2498 bills of 200 peso and 1249 bills of 500 peso.
How to apply systems of linear equations in real life equations
In this question we must translate the statement of the problem into mathematical expressions and then we must solve the resulting system. We need three equations that describe the quantities of 50 peso, 200 peso and 500 peso bills:
y = x - 5 (1)
0.5 · y = z (2)
x + y + z = 6250 (3)
The solution of the system of linear equations is described below:
x = 2503, y = 2498, z = 1249
For an amount of 6250 Peso, Hank have the quantities of the following denominations: 2503 bills of 50 peso, 2498 bills of 200 peso and 1249 bills of 500 peso. [tex]\blacksquare[/tex]
