Answer: 1150 turns
Step-by-step explanation: radius of wheel is 0,9 m
In one turn wheel moves 2·pi·0,9 m = 5,652 m
You divide 6500 m : 6,652 m = 1150
The number of complete turns each wheel makes in travelling the 6.5 km is 1150 turns
What is a circle?A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.
We know that circumference of the circle that has a radius of r is defined as the product of diameter to the pie value.
The circumference of the circle = 2πr
WE have been given the radius of wheel is 0.9 m
In one turn wheel moves 2πr
= 2 x π x 0.9 m
= 5.652 m
Now we have to divide 6500 m : 6.652 m
= 1150

In ΔQRS, the measure of ∠S=90°, RS = 2.2 feet, and QR = 4.5 feet. Find the measure of ∠Q to the nearest tenth of a degree.
Answer:
[tex]Q = 29.3^\circ[/tex]
Step-by-step explanation:
Given
[tex]\angle S = 90[/tex]
[tex]RS = 2.2ft[/tex]
[tex]QR = 4.5ft[/tex]
See attachment for ΔQRS
To calculate <Q, we make use of:
[tex]sin\ Q = \frac{Opposite}{Hypotenuse}[/tex]
Where
[tex]Opposite = RS[/tex]
[tex]Hypotenuse = QR[/tex]
[tex]sin\ Q = \frac{RS}{QR}[/tex]
[tex]sin\ Q = \frac{2.2}{4.5}[/tex]
[tex]sin\ Q = 0.4889[/tex]
Take arc sin of both side
[tex]Q = sin^{-1}(0.4889)[/tex]
[tex]Q = 29.3^\circ[/tex]

The graph is shaded to the right, because everything that is above -2 is allowed, so the shaded region is what is allowed to be true in this inequality.
The line is dotted because the inequality is only using greater than or less than, and not greater than or equal to, or less than or equal to.

A pile of earth removed from an excavation is a cone measuring 6ft high and 30ft across its base. How many trips will it take to haul away the earth using a dump truck with a capacity of 125 cubic feet?
Answer: 14
Step-by-step explanation:
Given
Excavation cone measures
height [tex]h=6\ ft[/tex]
Diameter [tex]d=30\ ft[/tex]
Truck can dump [tex]125\ ft^3[/tex] at a time
The volume of a cone is
[tex]V=\dfrac{1}{3}\pi r^2h[/tex]
Putting values
[tex]\Rightarrow V=\dfrac{1}{3}\times \pi\times 15^2\times 6\\\Rightarrow V=1413.9\approx 1414\ ft^3[/tex]
No of trips(N) required to accumulate this much volume is given by
[tex]\Rightarrow N=\dfrac{1414}{125}=13.3\approx 14[/tex]
Therefore, 14 trips are necessary to accumulate a cone of volume [tex]1414\ ft^3[/tex]

A grocery store stocks different flavors of peppermint sticks in 15 jars. The number of sticks in each jar varies from 0 to 49. Suppose you are creating a histogram to represent the situation. A. Which axis should be labeledas the num ber of jars for each flavor? B. What are possible intervals that COULD be appropriate for the histogram?
Answer:
The correct answers are:
A. The Vertical axis should be labelled as the Number of Jars for Each Flavour
B. an interval of 7 could be appropriate
Step-by-step explanation:
A. The number of jars for each flavour is the dependent variable against the flavour type, which is the independent variable, hence it is displayed on the vertical axis to show the height of the bars.
B. since the number of sticks in a jar vary from 0 to 49, dividing 49 by 7 will give 7 without a remainder, hence, an interval of 7 will be ideal for the plot, nd a total of 7 bars will be plotted. Intervals are: 0-7, 8-14, 15-21, 22-28, 29-35, 36-42, 43-49.

problems. Amanda is a student in the afternoon class.
She has already completed 11 homework problems.
How many more problems must she complete?
Answer:
17 problems.
Step-by-step explanation:
19 + 9 = 28
(Amanda is in the afternoon class, so she gets 9 more homework assignments than the morning class, which gets 19.)
28 - 11 = 17
(Amanda has already completed 11 homework problems.)

The Lee family made a 9-pound turkey for dinner. If each person will eat 13 of a pound, how many people will it take to finish the turkey?
Answer: 27people
Step-by-step explanation:
The turkey weighs 9 pounds.
Each member of the family will eat 1/3 of a pound.
If this is the case, the number of people that it would take to finish the turkey will be:
= Weight of turkey / Pounds eaten per person
= 9 ÷ 1/3
= 9 * 3/1

Gilded Gifts Company hires employees to make handmade greeting cards. The manager is determining how the time spent training new employees affects their production of greeting cards. The scatter plot below shows how many greeting cards each employee made the past month and the number of hours of training the employee received. A line of best fit is drawn.
Complete the statements based on the scatter plot.
The slope of the line of best fit is
. This means that for every additional hour of training,
more greeting cards are expected to be made per month.
Without any training, an employee is expected to make
greeting cards per month.
If an employee has 70 hours of training, the employee is expected to make
greeting cards per month.
Answer:
I think its A
Step-by-step explanation:
a. The equation of the trend line is c=5x+100.
b. The equation of the trend line is c=-5x+100.
c. As the hours of training increase by 5, the greeting cards made increases by 25.
d. As the hours of training increase by 5, the greeting cards made decreases by 25.
Answer:
The slope of the line of best fit is 5.
Without any training, an employee is expected to make 100 greeting cards.
If an employee has 70 hours of training, the employee is expected to make 450 greeting cards per month.
Step-by-step explanation:
First, find the slope of the line of best fit by substituting any two points on the line into the slope formula. The following calculation uses (10,150) and (20,200).
So, the slope of the line of best fit is 5.
The y-intercept is the point at which the line crosses the y-axis or when x = 0. So, the y-intercept of the line of best fit is 100.
The equation of the line of best fit can be represented in slope-intercept form, where the slope, m, is 5 and the y-intercept, b, is 100.
A slope of 5 in this situation means that for every additional hour of training, 5 more greeting cards are expected to be made per month. The y-intercept is 100 when the number of hours of training is 0. So, without any training, an employee is expected to make 100 greeting cards.
To find the number of greeting cards an employee would produce after receiving 70 hours of training, substitute x = 70 into the equation for the line of best fit and solve for y.
So, if an employee has 70 hours of training, the employee is expected to make 450 greeting cards per month.

In a class of 30 pupils the ratio of the number of boys to the number of girls is 7 : 8. How many girls are there?
Step-by-step explanation:
let the ratio 7:8 be 7x and 8x.
now
7x+8x=30
or, 15x=30
or, x= 30/ 15
or, x= 2
here
no. of boys = 7x= 7*2 = 14
no. of girls= 8x = 8*2= 16
hope this helps u...
Answer:
16 girls
Step-by-step explanation:
sum the parts of the ratio, 7 + 8 = 15 parts
Divide the number of pupils by 15 to find the value of one part of the ratio.
30 ÷ 15 = 2 pupils ← value of 1 part of the ratio, then
8 parts = 8 × 2 = 16 ← number of girls
