Answer:
52/[(8 - 2) + (10 - 3)]
Step-by-step explanation:
Jeff earns $8 and spends $2 each week.
Each week he keeps (8 - 2).
Joe earns $10 and spends $ each week.
Each week he keeps (10 - 3).
The total amount they keep each week is
(8 - 2) + (10 - 3).
If you divide the cost of the game by the amount they keep each week, you get the number of weeks.
Answer: 52/[(8 - 2) + (10 - 3)]

What is the slope of the line that passes through the points (-2, 1) and (5, 7)?
Answer:
The slope is 6/7
Step-by-step explanation:
The slope is equal to (y₂ - y₁)/(x₂ - x₁)
Point 1 is (-2,1)
Point 2 is (5,7)
((7) - (1))/((5) - (-2))
(7 - 1)/(5 + 2)
6/7
The slope is 6/7
What is 8.7 x 10-6 in standard notation?
A. 1/8.79 (fraction)
B. 8,700,000
C. 0.0000087
D. 0.000087
Answer:
a is the answer please tell me brainlist answer please please
Answer:
C.
Step-by-step explanation:
If the exponent n the 10 is negative you move the decimal to the left. If it is positive you move it to the right.
So 8.7 * 10^-6 you would move the decimal to the left 6 places
.0000087
Solve the equation for x. -2x + 5 = 37
Answer:
x= -16
Step-by-step explanation:
-2x+5=37
-2x=37-5
-2x=32
x= -16
Answer:
x= -16
Step-by-step explanation:
The goal in this problem is to get X on one side by itself.
We know that the opposite of subtraction is addition and the opposite of multiplication is division.
so to get 5 over to the right side, we need to subtract.
-2x+5=37 >>-2x= 37-5= 32
your problem now reads -2x= 32
We still have -2 on the left side and we need it to go to the right side so that X is by itself. The opposite of multiplication is division, so we will need to divide
-2x=32÷-2 >> x=-16

Answer: 4.27
Step-by-step explanation: I used a calculator.
Use a calculator to find the approximate value of the expression. Round the answer to two decimal places.
The cosine of the complimentary angle to 38°
a. 0.68
b. -0.16
C. -0.22
d. 0.62
Answer:
The cosine of the complementary angle to 38° is 0.62. Answer: d
Explanation:
Complementary Angle
Two angles x and y are complementary if
x+y=90°
The complementary angle of 38° is 90°-38°= 52°
Now use a calculator to find the approximate value of
[tex]\cos 52^\circ \approx 0.61566[/tex]
Rounding to two decimal places:
[tex]\cos 52^\circ \approx 0.62[/tex]
a. Incorrect. The cosine of 52° is not 0.68
b. Incorrect. The cosine of 52° is not -0.16
c. Incorrect. The cosine of 52° is not -0.22
d. Correct. The cosine of 52° is 0.62 to two decimal places.
41.2 x 1.5. Then explain where the decimal point should go and why
Answer:
This is really simple, here i'll explain:
Step-by-step explanation:
41.2 x 1.5=
count how many spaces are after the decimal point.
for example, 41.2 has 1 space after the decimal point. The decimal 1.5 also has 1 space after the decimal point. So if you add the spaces it would be 2 because 1 + 1 = 2
After that, take away the decimal point, and just multiply like you normally would.
412 times 15
this would be 6180
after you do the multiplication, you will add the decimal point.
The decimal point will go in between 1 and 8 because there were 2 spaces after the decimal point in the numbers, and if you add them it would be 2 spaces.
Hope this helps!
Answer:
41.2×1.5=61.8. because you always have to line up the decimals.

The electric usage for a computer repair company was charted over four months. What is the rate of change for the bill during that time? KWH used Billing 578 $109.82 1,033 $196.27 1,475 $280.25 1,754 $333.26 A. $0.56 per KWH B. $1.79 per KWH C. $0.19 per KWH
Answer:
The correct option is;
C. $0.19 per KWH
Step-by-step explanation:
The given data are;
KWH [tex]{}[/tex] Billing
578 [tex]{}[/tex] $109.82
1,033 [tex]{}[/tex] $196.27
1,475 [tex]{}[/tex] $280.25
1,754 [tex]{}[/tex] $333.26
Therefore, we have the rate of change, m, given as follows;
m =(Change in the amount paid)/(Change in the electric usage in the same period)
For the first and second month, the rate of change is therefore;
m = ($196.27 - $109.82)/(1,033 - 578) = $0.19 per kWH
Between the first and third month, the rate of change is given as follows;
m = ($280.25 - $109.82)/(1,475 - 578) = $0.19 per kWH
Between the first and fourth month, the rate of change is given as follows;
m = ($333.26 - $109.82)/(1,754 - 578) = $0.19 per kWH
Therefore;
The rate of change is constant and is $0.19 per kWH
Michele is purchasing new clothes for soccer practice for the upcoming season. She buys s pairs of shorts at $14.98 each. She also buys 5 shirts to go with each pair of shorts, and she buys 3 additional shirts. Each shirt costs $11.50.
Complete the statement below to write an expression for the amount Michele spends on her soccer practice clothes. Let s represent the number of shorts.
Simplify your expression completely before writing it in the spaces below.
Answer:
s14.98 + 92
Step-by-step explanation:
In order to make an expression for this word problem, all you have to do is follow along the steps in the problem:
s14.98 represents how many shorts Michele bought and how much they cost
8 * 11.50 represents how many shirts she bought and what they cost, but we need to simplify, so
8 * 11.50 = 92
Therefore, by adding the shorts and shirt together, we get the expression:
s14.98 + 92
Hope this helps :)
what does -2/7 > -4 indicate about the positions of -2/7 and -4 on the number line?
It means -2/7 is to the right of -4
Numbers on the right are larger than numbers on the left.
left < right
which flips to
right > left
-2/7 is to the right of -4
thats a lil obvious but i wont judge- ;-;
Which could be the first step in simplifying this expression? Check all that apply. (x^3x^-6)^2

Actually Welcome to the Concept of the Indices and BODMASS rule,
according to the BODMASS rule, we must always give high priority to the, parentheses "()" ,hence we will solve the bracket index powers first,
this we get as
[tex] ({x}^{3} . {x}^{ - 6}) ^{2} = > ( {x}^{3 - 6} )^{2} = = > ( {x}^{ - 3})^{2} [/tex]
hence, the above option is 2.) is correct.
-9^2-(-6)^2+3-20 i don’t understand the question
Answer: 28
-9^2 - (-6)^2 + 3 - 20
so follow order of operations
P = parentheses
E = exponents
D = divide
M = multiply
A = add
S = subtract
since there are no parentheses, do exponents
-9^2 = 81
-6^2 = 36
so now its
81 - 36 + 3 - 20
now follow order of operations
81 - 36 = 45
45 + 3 - 20
3 - 20 = -17
45 + -17 = 28
so your answer is 28

One negative one positive
Hope it helped
Answer:
[tex]\boxed {a = 6}[/tex]
Step-by-step explanation:
Solve for the value of [tex]a[/tex]:
[tex]3 - 6a = 9 - 6a[/tex]
-Take [tex]-6a[/tex] and add it to [tex]-6a[/tex]:
[tex]3 - 6a + 6a = 9 - 6a + 6a[/tex]
[tex]3 - a = 9[/tex]
-Subtract both sides by [tex]3[/tex]:
[tex]3 - 3 - a = 9 - 3[/tex]
[tex]\boxed {a = 6}[/tex]
Therefore, the value of [tex]a[/tex] is [tex]6[/tex].

In ΔLMN, n = 960 cm, ∠L=160° and ∠M=10°. Find the length of l, to the nearest centimeter.
Answer:
1,890.8cm
Step-by-step explanation:
Sine law!! So drawing the triangle helps, We know that the angle n is 10 because 180 - 10 -160 =10. Knowing that you can now use the sine law.
x/sin160 = 960/ sin 10
x= sin 160 (5528.4)
x= 1890.8cm

Ken and Donna are driving from Baltimore, MD to Richmond, VA for a wedding. The total distance they must drive is 131 miles. Since the reception is late, they decided to get a bite to eat along the way. They want the first part of the trip to be 65 miles more than the second part. How many miles will they drive before they stop?
Answer:
The distance they drive before they stop is 98 miles.
Step-by-step explanation:
Since Ken and Donna are supposed to drive a total distance of 131 miles from Baltimore, MD to Richmond, VA for the wedding. If the first part of the journey is supposed to be 65 miles more than the second part. Let the second part be x miles. So, the first part is x + 65 miles
Since the total distance covered is 131 miles,
x + x + 65 = 131
adding the x's, we have
2x + 65 = 131
subtracting 65 from both sides, we have
2x = 131 - 65
2x = 66
dividing both sides by 2, we have
x = 66/2
x = 33 miles.
So, for the first part the distance travelled is x + 65 miles, so, x + 65 = 33 + 65 = 98 miles. So, the distance they drive before they stop is 98 miles.
