Answer:
41.54 mph
Step-by-step explanation:
you need to find the total distanceand total time to find the average speed
use distance/time = speed equation
time = 1.5 hours + 40 mins = 2 hours 10 mins
distance= 20 + 70 = 90 miles
90/130 mins x 60 = 41.54 mph

Jane and 3 friends decided to split the cost of a pizza evenly. The total cost was $25.48. How much does each friend have to pay?
Answer:
$6.37
Step-by-step explanation:
Jane and 3 friends = Jane + another 3 people
= 4 people in total
Total Cost of pizza = $25.48
If 4 people split $25.48 evenly,
Amount each friend has to pay = Total Cost of pizza/Total number of people
= $25.48/4
= $6.37 per friend
Each friend has to pay $6.37 each if $25.48 is splitted evenly amongst them

An electrician bought 120 feet of electrical wire and used 105 feet of it
What percent of the wire went unused?
A 15%
B 12.5%
C 8.75%
D 7%
Answer:
B. 12.5%
Step-by-step explanation:
Find how much was unused:
120 - 105
= 15
To find what percent this is, divide it by 120:
15/120
= 0.125
Multiply this by 100:
0.125(100)
= 12.5
So, 12.5% of the wire went unused
The correct answer is B. 12.5%

What is the sum of 4 and its additive inverse?

The additive inverse is the opposite sign quantity so the sum of 4 and its additive inverse will be 0.
What is summation?A summation, also abbreviated as a sum, is the outcome of adding two or more numbers or quantities. Here are always an integer number of terms in a summation.
Given the number 4.
The sign of the number 4 is positive.
An additive inverse is a number whose sign is opposite to the number.
For example, the additive inverse of -5 is 5, and 5 is -5.
So additive inverse of 4 will be -4.
Now sum of 4 and -4
4 + (-4) = 0
Hence "The additive inverse is the opposite sign quantity so the sum of 4 and its additive inverse will be 0".

Let total number of eggs be x.So, 3% of x were broken and there were 18 broken eggs. We can write this as: 0.03*x =18x=18/0.03x= 600 eggs (answer).
Total number of eggs in the bags are 600.
What is Percentage?Percentage is a number or ratio that can be "expressed as a fraction of 100".
According to the question,
Percentage of broken eggs = 3%
Number of broken eggs = 3/100 = 0.03
To calculate the total number eggs,
[tex]\frac{3}{100}[/tex] (x) = 18
x = 1800/3
x = 600.

what is the area of the
rectangle?
Answer:
Step-by-step explanation:
The area of the rectangle is 240 square inches if the length of a rectangle is 8 inches longer than the width. If the ratio of the length to the perimeter is 5:16.
What is the area of the rectangle?It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
It is given that:
The length of a rectangle is 8 inches longer than the width. If the ratio of the length to the perimeter is 5:16
As we know, the two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.
Let l and w be the length and width of the rectangle:
l = 8 + w
w = l - 8
l/P = 5/16 (the length to the perimeter is 5:16)
P is the perimeter of the rectangle.
P = 2(l + w)
l/[2(l + w)] = 5/16
16l = 10(l + w)
8l = 5(l + l - 8)
8l = 10l - 40
2l = 40
l =20 inches
w = 20 - 8 = 12 inches
Area = 20x12 = 240 square inches
Thus, the area of the rectangle is 240 square inches if the length of a rectangle is 8 inches longer than the width. If the ratio of the length to the perimeter is 5:16.

The camping trip costs $165. How long will it take you to save enough money?
25 Points I guess.
Answer:
11 weeks
Step-by-step explanation:
$165 / 15 = 11 weeks
11 weeks
Hope that helps!
The equation of line is given by y = 15x and the number of weeks to save enough money is 11 weeks
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the number of weeks be x
Let the cost of trip be y
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P ( 4 , 60 )
Let the second point be Q ( 8 , 120 )
Now , the slope of the line between the two points is
Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 120 - 60 ) / ( 8 - 4 )
On simplifying the equation , we get
Slope m = 60 / 4
Slope m = 15
Now , the equation of line is y - y₁ = m ( x - x₁ )
Substituting the values in the equation , we get
y - 60 = 15 ( x - 4 )
On simplifying the equation , we get
y - 60 = 15x - 60
Adding 60 on both sides of the equation , we get
y = 15x
Now , the cost of the camping trip is $ 165
Substitute the value of y = 165 , we get
165 = 15x
Divide by 15 on both sides of the equation , we get
x = 165/15
x = 11 weeks
Therefore , the value of x is 11 weeks
Hence , the equation is y = 15x

Solve for the area of this triangle, explanation would be greatly appreciated!
9514 1404 393
Answer:
13√731 ≈ 351.48 cm²
Step-by-step explanation:
When given three sides of a triangle, there are a number of ways that the area may be calculated. Perhaps the most straightforward is the use of Heron's formula.
Where s is the semi-perimeter, the area is given by ...
A = √(s(s -a)(s -b)(s -c)) . . . . . . . . s = (a+b+c)/2
Here, the value of s is ...
s = (30 +30 +26)/2 = 43
A = √(43(13)(13)(17)) = 13√(43·17)
A = 13√731 ≈ 351.48 . . . . . square centimeters
_____
Additional comments
This triangle is isosceles, so the altitude can be found from the Pythagorean theorem:
h² +13² = 30²
h = √(900 -169) = √731
Then the area is ...
A = (1/2)bh = (1/2)(26 cm)(√731 cm) = 13√731 cm²
__
You can also find one of the angles using the Law of Cosines, then find the area from ...
Area = (1/2)a·b·sin(C) . . . . . . for any two sides a, b, and enclosed angle C
__
Ultimately, all of these methods are equivalent to Heron's formula.

A middle school took all of its 6th grade students on a field trip to see a ballet at a theater that had 3840 seats. The students left 2496 seats vacant. What percentage of the seats in the theater were filled by the 6th graders on the trip?
Answer:
The answer is 35%
Step-by-step explanation:
To work out percentage.
(No. Of students / Total Available Seats) * 100
1,344 ÷ 3840 = 0.35
0.35 * 100 = 35%
So, the answer is 35%
Hope this helps! :)
The percentage of the seats in the theater were filled by the 6th graders on the trip will be 35%.
What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
Total seats in theater = 3840
And, The students left 2496 seats vacant.
Now,
Find the percentage of the seats in the theater were filled by the 6th graders on the trip as;
Since, Total seats in theater = 3840
And, The students left 2496 seats vacant.
So, Number of students in 6th grade = 3840 - 2496
= 1344
Hence, The percentage of the seats in the theater were filled by the 6th graders on the trip;
= 1,344 / 3,840 x 100
= 35%
Thus, The percentage of the seats in the theater were filled by the 6th graders on the trip will be 35%.
