Answer:
39 MPH
Step-by-step explanation:
d = rt
13 times 3,
20x3=60.
60=1 hour
13M = every 20m
60 divided by 20 =3.
13 times 3 = 39.

Kayla is driving at 39 miles per hour.
What is average?The average is calculated as the product of all values divided by all possible values. It can also be described as mean. The mean in statistics is the average value for the particular sample or collection of data. It is determined by dividing the total number of observations by the total number of observations.
Given:
Kayla drove 13 miles in 20 minutes.
To find the average rate in miles per hour:
Miles / hour
= 1 / 1
Multiply by 3 to the rate,
So, 13 x 3 mils in 3 x 20 minutes.
39 miles per hour.
Therefore, the average rate is at 39mph.

Shane is a salesperson. He earns an hourly wage of $8.00 per hour, plus he receives a commission of 7% on sales he makes. Write an equation which would be used to determine his weekly salary, W, where, X, is the number of hours worked, and Y, is the amount of sales for the week.
Answer:
8X+.07Y=W
Step-by-step explanation:
x is your hours and y is your sales
he makes 8 an hour, hence 8X or 8 x X
7 percent written as a decimal is .07 and his commission for sales, so .07Y
add them together and you get your equation:

Please help me, I can’t figure this one out.
Answer:
A. This scatter plot has no association, no form, weak strength, and no apparent outliers.
Step-by-step explanation:
The scatter shows several data points plotted on the graph, of which show no particular trend.
Every data point on the plot are far apart from each other and do not follow any trend or have any shape, and as such show very weak strength.
We can hardly pick out which data point is an outlier.
There's also no form of association or whatsoever since no trend can be observed.
Therefore, we can conclude that:
"This scatter plot has no association, no form, weak strength, and no apparent outliers."

Answer: the one at the bottom second and third too
Step-by-step explanation:
The sum of the numbers X, Y, and Z is 40. The ratio of X to Y is 1:2 and the ratio of Y to X is 2:5. What is the value of Y?
Step-by-step explanation:
Since X : Y = 1 : 2, X = 0.5Y.
Since Y : Z = 2 : 5, Z = 2.5Y.
We have X + Y + Z = 4Y = 40. Hence Y = 10.

Ratio:A ratio in mathematics shows how many times one number is contained in another. For instance, if a dish of the fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio of 4:3). The ratio of oranges to the overall amount of fruit is 8:14, and the ratio of lemons to oranges is 6:8 (or 3:4) (or 4:7).A ratio can have any number of quantities, such as counts of people or things or measurements of length, weight, time, etc. Both numbers must be positive in most situations.Solution -

There are c amount in a box . 11 of the counters are green. Benedict take 20 counters at random from the box. 4 of these counters are green. Work out the estimate for the value of c.
Answer:
There are total 55 counters out of which 11 are green and 44 are other color.
Step-by-step explanation:
This is a ratio and proportion question. There are c amount of counters in the box .
The chosen have the same ratio as in the box
Green : total
4: 20
11: x
Using cross product rule
x * 4= 20 *11
x= 20*11/4
x= 55
So there are total 55 counters out of which 11 are green and 44 are other color.
Benedict take 20 counters out of which 4 are green.
Total number of counters are 55 in which 11 counters are green and 44 counters are other color.
Ratio and proportion:There are c amount in a box.
11 of the counters are green.
We have to find number of counters.
[tex]\frac{c}{11}=\frac{20}{4}\\ \\ 4*c=20*11\\\\c=\frac{20*11}{4}\\ \\c=55[/tex]
Hence, total number of counters are 55 in which 11 counters are green and 44 counters are other color.

A train travels 40 miles in 65 minutes. To the nearest tenth of a mile, how far does the train travel per minute?
Answer:
1.625 miles
Step-by-step explanation:
40 miles in 65 minutes means that every 65 minutes, 40 miles is travelled. To find the distance travelled per minute, divide 65 and 40:
65 minutes / 40 miles = 1.625 miles per minute. So every minute, the train travels 1.625 miles.

7m + 2 = 6n - 5
Write a formula for f(m) in terms of m.
Answer: m = 6/7n-1
Step-by-step explanation: to get 7m alone dirst we must subtract 2 from both sides so 2-2 = 0 and -5 - 2= -7 so 7m= 6n-7 and divide both sides by 7 to get m alone so 6n divided by 7 = 6/7n and -7 divided by 7 equals -1 so we're left with m= 6/7n-1
The formula for f(m) in terms of m is:
f(m) = (6m - 7) / 7
To write a formula for f(m) in terms of m, we need to isolate m on one side of the equation.
Given the equation 7m + 2 = 6n - 5, we can start by moving all terms involving m to one side and all terms involving n to the other side:
7m - 6n = -5 - 2
Simplifying:
7m - 6n = -7
Now, we can express m in terms of n:
7m = 6n - 7
Dividing both sides of the equation by 7:
m = (6n - 7) / 7
Thus, the formula for f(m) in terms of m is:
f(m) = (6m - 7) / 7
This formula allows us to calculate the value of f(m) based on the given relationship between m and n. By substituting different values of m into the formula, we can determine the corresponding values of f(m) for those inputs.

Michael and Jane want to build a kite with four equal sides. They know that KT and TE are eight inches which makes point T the midpoint of (KE). Describe how Michael and Jane can be absolutely certain that KI, IE, ES, and KS are all the same lengths.
Answer:
with the help of the theorems of triangles AAS ≅AAS
Step-by-step explanation:
We see from the figure that K and E are equidistant from T. To be absolutely certain that KI, IE, ES, and KS are all the same lengths the diagonals must bisect each other perpendicularly at 90 degrees for the given figure to be a rhombus. A rhombus is a parallelogram in which all sides are equal.
If we look at the figure more carefully then we find that there are four triangles. Of the which the two sides KE and TE of the triangles are equal. Also the diagonal indicates that they both have a 90 degrees angle. Hence the two triangles KST and EST are equal.
To prove that triangle KEI is equal to Triangle KES.
Both have one line common which equal to both.
Both have a mid point T on the common line which divides the both bigger triangles into smaller triangles making 90 degrees angle. Hence the angles
KEI and KSE are of 90 degrees which are also opposite.
The angles SKT and IKT and angles IET & SET are equal and opposite angles. Thus both the triangles KEI and triangle KES are equal and opposite having equal and opposite sides.
Find the distance travelled by Rama if she takes two rounds of a rectangular park whose length is 8 km and breadth is 12 km.
Answer:
80 km
Step-by-step explanation:
First, find the perimeter of the park.
2(12 + 8) = 2(20) = 40 km
Since Rama travels around the park twice, multiply the perimeter by 2.
40(2) = 80 km
9514 1404 393
Answer:
80 km
Step-by-step explanation:
The perimeter is twice the sum of length and breadth:
P = 2(length +breadth)
P = 2(8 km +12 km) = 40 km
Twice around is then ...
2 × 40 km = 80 km . . . . distance traveled by Rama
