Susan, Deon, and Felipe sent a total of 160 text messages during the weekend. Felipe sent 4 times as many messages as Susan. Deon sent 10 more messages than Susan. How many messages did they each send
Answer:
Susan sent 25 messages
Felipe sent 100 messages
Deon sent 35 messages
Step-by-step explanation:
160 = x + 4x + x + 10
160 = 6x + 10
6x = 150
x = 25
Please help please...
Answer:
(2x + 5)
Step-by-step explanation:
2(x + 1) + 6x = 4(2x + 5) + 2
2x + 2 + 6x = 8x + 20 + 2
8x + 2 = 8x + 22
Because both sides are 8x it will have no solution

how to tell if a triangle is legal?
Step-by-step explanation:
Approach: A triangle is valid if sum of its two sides is greater than the third side. If three sides are a, b and c, then three conditions should be met.
The function f is defined by f(x )=150÷x −z , where z is constant.Find z if the value of f at x = 1 5 is equal to 250.
Answer:
-150
Step-by-step explanation:
The function f is defined by f(x )=150÷x −z , where z is constant. Find z if the value of f at x = 1 5 is equal to 250.
Given the function;
f(x )=150÷x −z
This can also be written as;
f(x )=150/x −z
If f(1.5) = 250, hence;
at x = 1.5, f(x) = 250
Substitute;
250 = 150/1.5 - z
250 = 100 - z
z = 100 - 250
z = -150
Hence the value of z is -150
A company had a tractor destroyed by fire. The tractor originally cost $136,000 with accumulated depreciation of $69,900. The proceeds from the insurance company were $31,000. The company should recognize
Answer: A loss of $35,100
Step-by-step explanation:
The tractor had cost $136,000 and had accumulated a depreciation of $69,900.
This means that the net book value of the tractor was:
= 136,000 - 69,900
= $66,100
The insurance company was supposed to give them this amount but instead gave them $31,000. They will therefore suffer a loss of:
= 66,100 - 31,100
= $35,100
The Eiffel Tower is 324 m tall. If a tourist is looking at it from 100 m away from the base,
what is the angle at which they are tilting their head to see the top?
Answer:
80,94º
Step-by-step explanation:
What I've done is, first draw a triangle with a 90º angle and write down the height (324m) and the tourist's distance (100m).
So I calculated the tangent of the angle of the tourist.
The formula is tan=Oposite side/adjacent
[tex]tan=\frac{opposite side}{adjacent}[/tex]
[tex]tan=\frac{324}{100} =3.24[/tex]
And now with your calculator you press "shift" and "tan". Then introduce 3,24 and it will give you the result (80,94º).
I hope it helped.

The table shows the price for ingredients in trail mix at the local grocery store. Joshua buys 1/5 pound of mixed nuts. 1/2 pound of chocolate candies, and 1 1/4 pound of granola to make the trail mix. How much did Joshua spend to make the trail mix? TYPE COST (per pound) Mixed Nuts $2.50 Chocolate Candies $3.40 Granola $5.60
Answer:
$9.20
Step-by-step explanation:
Mixed nuts = 1/5
Chocolate candies = 1/2
Granola = 1 1/4
Cost of the trail mix
Mixed Nuts $2.50
Chocolate Candies $3.40 Granola $5.60
= 1/5 * 2.50 + 1/2 * 3.40 + 1 1/4 * 5.60
= 0.5 + 1.7 + 7
= $9.20

Which measure results in the highest value for the data given?
26, 29, 29, 17, 33, 24, 32, 24, 21, 29
mean
range
median
mode
Answer:
Mode
Step-by-step explanation:
29 occurs 3 times
Step-by-step explanation:
MEAN
add up all the numbers, then divide by how many numbers there are.
26+29+29+17+33+24+32+24+21+29/10
264/10
132/10 or 26.4
RANGE
The Range is the difference between the lowest and highest values.
lowest value: 17
highest value: 33
33-17= 16
MEDIAN
Arrange your number in numerical order:
17, 21, 24, 26, 29, 29, 29, 32, 33
Count how many numbers you have: 10
Since it's an even number divide 10 by 2: 5
Go to the number in that position and average it with the number in the next higher position to get the median.
5th position: 26
6th position: 29
26+29/ 2= 27.5
Therefore, the median is 27.5
MODE
To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.
17, 21, 24, 24, 26, 29, 29, 29, 32, 33
Therefore, thee mode is 29
Which fraction is equivalent to 12.5%?
A. one eighth
B. five over four
C. sixteen over twenty five
Answer:
One eighth
Step-by-step explanation:
By multiplying each fraction by 100, you can get the percentage.
(1/8) x 100 = 12.5
(5/4) x 100 = 125
(16/25) x 100 = 64
Answer:
A
Step-by-step explanation:
100 / 12,5 = 8
12,5% = 1/8

A student takes a mathematics test scores of 52 and 64. What score on a third test will give the student an average of 60?\
Answer: 64
Step-by-step explanation:
To score an average of 60 in the three tests, the total score of the test should be: = 60 × 3 = 180
Since the student already has scores of 52 and 64, the score in the third test will be:
= 180 - (52 + 64)
= 180 - 116
= 64

Match each amount in the situation with the expression that represents it.
Answer:this is the order of the things to put them
number of bouquets: 5
mass of bouquets: 3d+4t+v
mass of the tulips in one bouquet: 4t
mass of the daffodils in one bouquet: 3d
Step-by-step explanation:
In Rectangle ABCD, m
Answer:
m∠ACD = 24°
Step-by-step explanation:
Measure of the interior angles of a polygon = [tex]\frac{(n - 2)\times 180}{n}[/tex]
Therefore, measure of the interior angles of a rectangle = [tex]\frac{(4 - 2)\times 180}{4}[/tex]
= [tex]\frac{360}{4}[/tex]
= 90°
m∠BCD = 90°
Since, m∠BCD = m∠BCA + m∠ACD
90° = 66° + m∠ACD
m∠ACD = 90° - 66°
= 24°
Therefore, measure of angles ACD is 24°.
