On Monday, 344 students went on a trip to the zoo. All 6
buses were filled and 8 students had to travel in cars. How many students were
in each bus ?
Answer:
56 students were in each bus is our answer
Step-by-step explanation:
This is true because if 8 students went in cars then we have to subtract 8 from 344, so we get 336 then from there we divide 6 from 336 giving us 56, thus 56 is our answer.

Find x. Then find the measure of angles A, B and C.
Answer:
x= 11
A=59
B= 37
C = 84
Step-by-step explanation:
A triangle adds up to 180 °.
So the equation will be a °+ b° + c° = 180°
Next, you combine like terms.
[tex]6x + 3x + 9x+4-15-7 = 180\\18x-18=180[/tex]
Then inverse operation,
[tex]18x-18=180\\18x=198\\x=11[/tex]
After to get a, b, and c you just need to plug in x.
[tex]6(11)-7=a\\3(11)+4 = b\\9(11)-15=c[/tex]
The table below shows the ages of employees under 30 at a company and their annual salaries.Choose the scatter plot that shows the data.
Use the data, construct a scatter plot between salary in thousands ($) and Age (yr).
What is scatter plot?Using Cartesian coordinates, a scatter plot (also known as a scatterplot, scattergraph, scatter chart, scattergram, or scatter diagram) is a form of plot or mathematical diagram that shows the values of typically two variables for a set of data. One more variable can be shown if the points are coded (by color, shape, or size).
here, we have,
The data are shown as a series of points, with each point's value dictating its position on the horizontal axis and its value dictating its position on the vertical axis.
using the data from the question, a scatter plot is construct and attached with it.

the scale of the map is 1/4 inch =12 miles what is the distance in between Harrisburg and Leighton if 4.5 inches.
7th Grade Math
Answer:
216 miles :3
Step-by-step explanation: alright so is it is 4.5 you just divide 1/4 by 4.5 (
18) 18 x 12 = 216 miles :3
Answer:
Step-by-step explanation:
1/4 inch=12 miles Harrisburg and Leighton= 4.5 inches
1) Set up a proportion: ¼ /12 miles = 4.5 inches/ x miles
(inches across from inches
miles across from miles )
2) Use cross-products to solve: ¼x= 12(4.5)
¼x/¼ = 54/ ¼
x=216miles
The distance between Harrisburg and Leighton is 216miles

A ball shaped like a sphere has a radius of 1.9 centimeters. Which measurement is closest to the volume of the ball in cubic centimeters?
Answer:
28.73
Step-by-step explanation:
V=4
3πr3=4
3·π·1.93≈28.73091
Answer:
Step-by-step explanation:
Volume =
4 × π × r³ / 3 <----- This is our volume equation
= 4 × π × 1.9³ / 3 (Substituted the unknown r for the radius given, 1.9 cm)
= 4 × π × 6.859 / 3 (Cubed it, aka: Multiplied 1.9 by itself thrice, 1.9 × 1.9 × 1.9
= 4 × 21.548184011 / 3 (Multiplied 6.859 by pi "π")
= 86.1927360439 / 3 (Multiplied that by 4)
= 28.7309120146 cm³ (Divided it by 3, gave it a ³ dimension because it is 3D, volume.
≈
28.73cm³ or 28.7cm³ or 29cm³. (rounded answers, hundreths, tenths and ones)

a can of soup has a diameter of 6cm and height of 9cm. How much soup will the can hold (use 3.14) round to the nearest hundredth
Answer:
V = Π (4)2*12
V = 603.19 cm3
Step-by-step explanation:
A soup can is a cylinder.
The formula for volume of a cylinder is the following: V= Πr2h.
We are given the height which is 12 (h=12) and the diameter which is 8 (d=8).
The formula asks for radius so we divide the diameter by 2.
r =8/2 = 4.
Now we can just plug the numbers into the formula
V = Π (4)2*12
V = 603.19 cm3
Since the units of measure are in centimeters, the volume will be measured in cubic centimeters.

"what is the value of a in the equation 81^b=a^4b"
Answer:
Step-by-step explanation:
The value of a in the equation [tex]81^b = a^4^b[/tex] will be 3.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ [tex]81^b = a^4^b[/tex]
Now,
Solve the expression for the value of b as;
⇒ [tex]81^b = a^4^b[/tex]
Since, 81 = 3⁴
So, We get;
⇒ [tex]3^4^b = a^4^b[/tex]
By comparing, we get;
⇒ a = 3
Thus, The value of a in the equation [tex]81^b = a^4^b[/tex] will be 3.
