José made these grades on tests: 78, 88, 98. Without doing any computing, what is his average?
Answer:
88 is the average
Step-by-step explanation:
78 + 88 + 98 = 264
264 / 3 = 88 ( you divide by the amount of numbers you have, in this case there are three numbers)
The histogram to the right represents the weights (in pounds) of members of a certain high-school mathmath team. How many team members are included in the histogram?
Answer:
13 team members are included in the histogram.
Step-by-step explanation:
Consider the provided information.
The required histogram is shown in the figure.
We need to find the team members included in the histogram.
For this, we will add the frequency or the height of each bar.
2+1+1+5+1+3=13
Hence, 13 team members are included in the histogram.

4/3=-6e-5/3
solve for "E" plz
Answer:
e=-1/2
Step-by-step explanation:
4/3=-6e-5/3
Multiply both sides by 3:
4=-18e-5
Add 18e to both sides:
18e+4=-5
Subtract 4 from both sides:
18e=-9
Divide both sides by 18:
e=-1/2

Megan budgeted $300 for her shopping trip. She spent $61.50 on jewelry at Revin Jewelry. What percent of her budget did she spend on jewelry? (write the exact percentage)
Answer:
20.5%
Step-by-step explanation:
Here, we want to calculate the % spent on Jewelry
To get that, we divide the amount spent on Jewelry by the total budget and multiply by 100
That will be;
61.5/300 * 100% = 20.5%

Find the distance between C(-8,-5) and D(-2,3).
Find the midpoint of CD.
Answer:
10 units and (- 5, - 1 )
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = C(- 8, - 5) and (x₂, y₂ ) = D(- 2, 3)
d = [tex]\sqrt{(-2+8)^2+(3+5)^2}[/tex]
= [tex]\sqrt{6^2+8^2}[/tex]
= [tex]\sqrt{36+64}[/tex]
= [tex]\sqrt{100}[/tex]
= 10
Calculate the midpoint using the midpoint formula
( [tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
= [tex]\frac{-8-2}{2}[/tex], [tex]\frac{-5+3}{2}[/tex] )
= [tex]\frac{-10}{2}[/tex], [tex]\frac{-2}{2}[/tex] )
= (- 5, - 1 )

Answer:
2) 44°Step-by-step explanation:
CA and CB are perpendicular to OA and OB, so the angles A and B are right angles.
Angles AOB and ACB sum to 180°
3x + 10 + 38 = 1803x = 180 - 483x = 132x = 132/3x = 44Correct option is 2) 44°
Chrystelle's mother is 1 2/3ft taller than Chrystelle. If
Chrystelle is 3 1/2 ft tall, how tall is her mother?
Answer:
4 5/6 feet.
Step-by-step explanation:
The least common multiple for 2 and 3 is 6, so if we change the denominators to 6, we get Chrystelle's height as 3 3/6, and her mother is 1 4/6 ft taller than her.
3 3/6 + 1 4/6= ?
(Written as an Improper fraction)
21/6 + 10/6 = 31/6
31/6 = 4 5/6.
I hope this helps!
Answer:
first make it so the denominator is the same on bothers sides. a common denominator for both is 6 so
Chrystelle mom: 1 2/3 taller. multiply the fraction by 2/2 so 1 4/6
chrystelle: 3 1/2 feet tall. multiply the fraction by 3/3 so 3 3/6
now just add to figure out so
3 3/6 + 1 4/6 = 4 7/6 which simplifies down to 5 1/6
so chrystelles mom is 5 1/6 feet tall

You were in the car with a family member. You started with 7/10 of a tank of gas, and when you got home you had ⅓. How much gas did you use?
9514 1404 393
Answer:
11/30 of a tank
Step-by-step explanation:
The amount used is the difference between the starting amount and the ending amount:
7/10 -1/3 = 21/30 -10/30 = 11/30 . . . . of the tank

You are comparing 3 different cell phone plans to see which is the cheapest:
Plan A costs a basic fee of $30 per month and $10 for every GB of data used
Try writing each plan as an
equation in y = mx + b form where
Plan B costs a basic fee of $80 per month with unlimited data
=GBs used and y total cost.
Plan C costs a basic fee of $50 per month and $5 for every GB of data used
You're looking to replace the m and
b in the equation. For Plan A, where
a) Write an equation for each plan that calculates the total cost (y) in terms of GB of data used (x) would the $30 go? Where would
the
Plan A:

b) Graph each plan on the following set of axes.

c) When does Plan A cost the same as
Plan C?
80

d) Which plan is best if you only use 0-
4 GBs of data a month?
40:
20.
GBs of
8 10 data used
4
6
e) When does Plan B become the best
deal?
Answer:
Plan A equation: y = 10x + 30
Plan B equation: y = x + 80
Plan C equation: y = 5x + 50
Plan A costs the same as Plan C in 4 months
Plan A is the better option if you use 0 - 4 GBs of data each month
Plan B becomes the better deal when 8 months pass
Step-by-step explanation:
When does Plan A cost the same as Plan C?
Set the equations equal to each other (the cost) and solve for x (time in months)
10x + 30 = 5x + 50
5x = 20
x = 4 months
Which plan is best if you only use 0-4 GBs of data a month?
Test the maximum and minimum values to check which plan costs less
At 0 GBs of data used per month
Plan A: y = 0 + $ 30 = $30 total
Plan B: y = 0 +$80 = $80 total
Plan C: y = 0 + $50 = $50 total
At 4 GBs of data used per month
Plan A: y = $ 40 + $ 30 = $ 70
Plan B: y = $ 4 + $ 80 = $ 84
Plan C: y = $ 20 + $ 50 = $ 70
Comparing the plans at maximum and minimum amount of GBs used, only one plan has the lowest cost overall. Even though Plan C is the same price at 4 GBs as Plan A, when you use 0 GBs you will end up paying more in Plan C than Plan A. Therefore, Plan A is the better option
When does Plan B become the best deal?
When you plot the different Plans on a graph, the slope intercept of x = 7.5 (rounded up to 8) yields the lowest cost for plan B

Answer:
h = 1/5
Step-by-step explanation:
The formula to find the volume of this prism is b × w × h (base × width × height). Since you are given the volume, you can divide the volume by the other two dimensions to find the height.
V = b × w × h
1/100 = 1/4 × 1/5 × h
1/100 ÷ 1/4 ÷ 1/5 = h
h = 1/5

Which angle must also measure 85°?
22
0_5
_11
Answer:
angle 11 they are vertically opposite.
∠11 must also be 85 degrees.
What are vertically opposite angles?Angles that are vertically opposed to one another at a certain vertex are formed by two straight lines intersecting. Angles that are vertically opposed to one another are equal. They are referred to as vertical angles at times.
As per the given data:
∠9 = 85°
From the diagram, ∠9 and ∠11 are vertically opposite angles.
∴ ∠9 = ∠11
∠11 must also measure 85°.

URGENT!!! Can someone help me with this? It’s volume of cones!!!
Answer:
1232 m^3 to nearest whole number.
Step-by-step explanation:
The volume of a cone = 1/3 π r^2 h where r = radius of base and h = height.
The radius of the base = 1/2 * 14 = 7m.
The height can be found by using the Pythagoras theorem:
25^2 = h^2 + 7^2
h^2 = 625 - 49 = 576
h = √576 = 24m
So the volume = 1/3 π * 7^2 * 24
= 1231.504 m^3.
