Answer:
Step-by-step explanation:
Formula
Area = 1/2 (b1 + b2)*h
Givens
b1 = 5
b2 = 11.5
h = 4.5
Solution
Area = 1/2 (5 + 11.5)* 4.5
Area = 1/2 (16.5)*4.5
Area = 1/2 (74.25)
Area = 37.125
Jeremiah missed 68 questions on his multiple choice history final and earned a grade of 66%. How many total questions were on the final exam?
Answer:
200 questions
Step-by-step explanation:
If he missed 68 questions and got a 66%, that means 68 is 34% of the total number of questions
To find the total questions, divide 68 by 0.34
68/0.34
= 200
So, there were 200 total questions on the final exam

This question has a slope of zero.
Step-by-step explanation:
When trying to solve a problem like this, what I recommend doing is subtracting the y value in the first ordered pair from the y value in the second ordered pair, and doing the same for the x values. To write it as a formula,
y2 - y1
––––– = m the 2 in the formula means that the y or x value was from the
x2 - x1 second ordered pair. The 1 means it was from the first
ordered pair. The m means slope.

Answer:
∠ A = 82°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
A is an exterior angle of the triangle, then

Answer:
Other needs =25,2 degrees
insurance = 100,8 degrees
Taxes= 7,2
Housing = 57,6
food= 57,6
childcare = 64,8
transportation = 46,8
Step-by-step explanation:
Its % of 360 degrees so you have to calculate the percentage of each categorie on 360 degrees to find the angles. Exemple, for the Other needs, you take 7% out of 360 degrees and you find that it is equal to 25,2. (7% x360 degrees /100)

Juan has 240 marbles. This is three times as many marbles as Jon and Jeremy have combined. If Jon has 50 marbles, how many marbles does Jeremy have?
Answer:
30
Step-by-step explanation:
Let x = number of marbles Jon has
y = number of marbles Jeremy have
3(X + Y) = 240
3(50 + Y) = 240
Divide both sides by 3
50 + Y = 80
Solve for y
Y = 30

9. Write the equation that expresses the table below.
Answer:
y = 10x
Step-by-step explanation:
When x = 2, y = 20
When x = 5, y = 50
When x = 7, y = 70
In each of these examples, y = 10 * x.
The answer is y = 10x.
Which of the following objects exerts a gravitational force?م the Sun the Moon the Earth a basketball an apple
Answer:
Please rate as brainliest.
Step-by-step explanation:
The Moon exerts its force of gravity; since it's smaller and lighter than Earth, we would discover we weigh around a sixth of our weight on Earth if we could weigh ourselves on it. One could ask why the Moon doesn't fall on Earth as an apple from the tree.
A hiking trail rises 6 feet for every horizontal change of 100 feet. What is the slope of the hiking trail?
Given:
A hiking trail rises 6 feet for every horizontal change of 100 feet.
To find:
The slope of the hiking trail.
Solution:
We have,
Rise = 6 ft
Run = 100 ft
We know that
[tex]Slope=\dfrac{Rise}{Run}[/tex]
[tex]Slope=\dfrac{6}{100}[/tex]
[tex]Slope=0.06[/tex]
Therefore, the slope of the hiking trail is 0.06.
The slope of the hiking trail is equal to 0.06.
Given the following data:
Vertical distance (rise) = 6 feetHorizontal distance (running) = 100 feetTo find the slope of the hiking trail, we would use the following formula:
Slope is the ratio of the vertical distance measured to the horizontal distance measured.
Mathematically, the slope of a hiking trail is given by the formula:
[tex]Slope = \frac{Rise}{Running}[/tex]
Where:
V is the rising vertical distance of an object.H is the horizontal distance an object runs through.Substituting the given parameters into the formula, we have;
[tex]Slope = \frac{6}{100}[/tex]
Slope = 0.06

he two-way table shows the medal count for the top-performing countries in the 2012 Summer Olympics. A 5-column table has 5 rows. The first column has entries United notes, China, Russia, Great Britain, Total. The second column is labeled Gold with entries 46, 38, 24, 29, 137. The third column is labeled Silver with entries 29, 27, 26, 17, 99. The fourth column is labeled Bronze with entries 29, 23, 32, 19, 103.

The probability that a randomly selected silver medal was awarded to Great Britain is StartFraction 17 Over 99 EndFraction. The probability that a randomly selected medal won by Russia was a bronze medal is StartFraction 32 Over 103 EndFraction. The probability that a randomly selected gold medal was awarded to China is StartFraction 88 Over 137 EndFraction. The probability that a randomly selected medal won by the United States was a silver medal is StartFraction 104 Over 339 EndFraction.
Answer:
The all-time medal table for all Olympic Games from 1896 to 2018, including Summer Olympic Games, Winter Olympic Games, and a combined total of both, is tabulated below. These Olympic medal counts do not include the 1906 Intercalated Games which are no longer recognized by the International Olympic Committee (IOC) as official Games. The IOC itself does not publish all-time tables, and publishes unofficial tables only per single Games. This table was thus compiled by adding up single entries from the IOC database.[1]
The results are attributed to the IOC country code as currently displayed by the IOC database. Usually, a single code corresponds to a single National Olympic Committee (NOC). When different codes are displayed for different years, medal counts are combined in the case of a simple change of IOC code (such as from HOL to NED for the Netherlands) or simple change of country name (such as from Ceylon to Sri Lanka). As the medals are attributed to each NOC, not all totals include medals won by athletes from that country for another NOC, such as before independence of that country. Names in italic are national entities that no longer exist. The totals of NOCs are not combined with those of their predecessors and successors.

Calculate the areas and perimeters of each shapes, start bu calculating any missing sides.
Answer:
Perimeter of A = 46cm
Area of A = 112cm^2
Perimeter of B = 61cm
Area of B = 118cm^2
Step-by-step explanation:
So there are two shapes. I divided one into 2 parts ( shape A ) . And the other into three ( shape B
Shape A:
PERIMETER = S + S +S +S + S + S + S + S ( THE SHAPE HAS 8 SIDES )
= 5 + 5 + 20 + 11 + 3 + 3 + 5 + 4 ( THIS INCLUDES THE MISSING SIDES )
= 46 CM
AREA- To find the area you divide the shape
Part 1 - 4* 3 = 12cm^2 Part 2 - 20 * 5 = 100cm^2
Final part ( add part a and b ) - 12 + 100 = 112cm^2
Shape B:
PERIMETER = S + S + S + S + S ..,........ (UNTIL YOU GET TO 12 SIDES PROVIDED THE SHAPE HAS 12 SIDES :) )
= 12 + 2 + 2 + 4 + 5 + 4 + 4 + 4 + 6 + 6 + 12 + 5
= 61 CM
AREA- To find the area you divide the shape
Part 1 - 12* 2 = 24cm^2 Part 2 - 4 * 3 = 12cm^2 Part 3 - 12 * 6 = 72 cm ^2
Final part ( add part a, b and c ) - 12 + 72 + 24 = 108cm^2
