To get the unit rate, divide the miles by the hours
Unit rates
1000 miles in 2 hours = 1000/2 = 500
I'm guessing you meant 100 miles not 1000 miles
100 miles in 2 hours = 100/2 = 50

The value of y is directly proportional to the value of x. If y = 25 when x = 120, what is the value of y when x = 72?
Step-by-step explanation:
y directly proportional to X
y=kx
when k is constant
y is 25 and X is 120
25=k120
divide both sides by 120
25/120
k=25/120
there fore the law connecting is 25/120
what is the value of y when x = 72? 25/120*72=3
therefore y is 3

Aaliyah has $82,845 in a savings account that earns 12% annually. The interest is not
compounded. How much interest will she earn in 5 years?
Answer:
$49707Step-by-step explanation:
Amount of 12% simple interest for 5 years on sum of $82845 is:
$82845*5*(12/100) = $49707$82,845 × 12% × 5
= $82,845 × 0.6
= $49,707
Which rational number equals 0 point 6 with bar over 6? (5 points) a 2 over 3 b 6 over 10 c 4 over 5 d 6 over 5
9514 1404 393
Answer:
a. 2/3
Step-by-step explanation:
The bar over the 6 means the digit is repeated indefinitely. A bit of algebra can turn a repeating decimal into a fraction. Let x represent the value of the repeating decimal.
[tex]x=0.6\overline{6}\\\\10x=6.6\overline{6}\\\\10x-x=6.6\overline{6}-0.6\overline{6}\\\\9x=6\\\\x=\dfrac{6}{9}=\boxed{\dfrac{2}{3}}[/tex]

The attachment shows the long division of 2/3 gives a repeating decimal with a repeating digit of 6. You can tell the quotient repeats when the new dividend (after subtraction) is equal to a dividend you have seen before. In this case, the dividend is repeatedly 20, and the quotient digit is repeatedly 6.
The point of the long division is to show you that 2/3 is the correct answer choice for a rational number equivalent to 0.666...(repeating).
Find the perimeter and area of the shape based on the information provided.
Answer:
Area of the shape=241.2cm^2
Perimeter of the shape=76.08cm
Step-by-step explanation:
Find the base for the first triangle = tan(75°)=O/A
= A=30/tan(75°)
=A = 8.04cm (2decimal place)
Area of first triangle= 1/2×Base×height
=1/2×8.04cm×30cm
=120.6cm^2
So total area for the shape is = 2×120.6cm^2
=241.2cm^2
Perimeter of the shape = 2(30cm+8.04cm)
=76.08cm

Line K has a slope of -5. Line j is perpendicular to line k and passes through the point (5, 9). Create the equation for line j. (Please help me)
Answer:
y = 1/5 x + 8
Step-by-step explanation:
slope of line j: m = -(1/-5) = 1/5
j pass (5,9): (y-9)/(x-5) = 1/5
y-9 = 1/5(x-5) = 1/5 x - 1

Which pair of triangles must be similar?
A.Triangles 1 and 2 are equilateral.
B.Triangles 3 and 4 each have an 80 degree angle.
C.Triangle 5 has a 80 degree angle and a 30 degree angle, and Triangle 7 has a 70
degree angle
D.Triangle 7 has 2 50 degree angle, and Triangle 8 has a 50 degree angle and a 100
degree angle
Answer:
Step-by-step explanation:
This question involves the concept of similar triangles.
The pair of triangles that are similar are "B and D".
A pair of triangles is termed as similar triangles if the two angles of both the triangles are equal to each other. Hence, we will check this condition for each pair given in the question.
A.
Only one angle is given to be equal for both the triangles, while the other two angles are unknown. Hence, this pair can not be termed as similar.
B.
For an isoceles triangle, two sides and two angles of the triangle are equal. Considering the 40° angle to be the equal angle, we can safely conclude that the two angles of both the triangles in the pair are the same. Hence, this pair can be termed as similar.
C.
Triangle 5 has angles: 30°, 90° and (180°-30°-90°) = 60°. While triangle 6 has angles: 30°, 70°, and (180°-70°-30°) = 80°. Since all the angles of both the triangles are different. Therefore, they can not be termed as similar.
D.
Triangle 7 has angles: 50°, 20° and (180°-50°-25°) = 105°. While triangle 6 has angles: 50°, 105°, and (180°-50°-105°) = 25°. Since all the angles of both the triangles are equal. Therefore, they can be termed as similar.
Bridget, Brian & Caroline share some money in the ratio 4 : 9 : 4.In total, Bridget and Caroline receive £48.How much does Brian get?
Answer:
£54
Step-by-step explanation:
According to the ratio:
Bridget = 4/17
Brian = 9/17
Caroline = 4/17
____
So if Bridget and Caroline receive £48, that would mean £48 is 8/17 of the total amount. We can find 1/17 of the money by dividing £48 by 8.
48 / 8 = 6
And then multiply that by 9 to find 9/17 of the money (the amount Brian has).
6 x 9 = 54

Part B: What was the percent markdown, rounded to the nearest whole percent?
Answer:
$15
I don't know the percentage.
Step-by-step explanation:
50 + 50 = 100, 2 + 2 = 4, .50 + .50 = 1
100 + 4 = 104 + 1 = 105

Roberto works in a home appliance store she is paid $195 per week and 3% on all sales over $1000 during one year her average weekly sales were $7800 about how much did she earned weekly? about how much did she earned during the year?
Step-by-step explanation:
she gets $195 per week plus 3% on sale OVER $1000.
ok. so, her weekly sales were $7800.
that means we need to calculate 3% of ... $6800 !
as she gets the commission only on sales that are over $1000.
6800 = 100%
1% = 100%/100 = 6800/100 = 68
3% = 1%×3 = 68×3 = $204
so, she earned $195 + $204 = $399 per week
and as there are 52 weeks per year, she then earned
399×52 = $20,748 per year.

3y + 15 = 2x + 15 =
Answer:
x = 3/2y
y = 2/3x
Step-by-step explanation:
x = 3/2y
Swap sides so that all variable terms are on the left hand side
2x + 15 = 3y + 15
Subtract 15 from both sides
2x = 3y + 15 - 15
Subtract 15 from 15 to get 0
2x = 3y
Divide both sides by 2
2x/2= 3y/2
Dividing by 2 undoes the multiplication by 2
X = 3y/2
Y = 2/3x
Subtract 15 from both sides
3y = 2x + 15 - 15
Subtract 15 from 15 to get 0
3y = 2x
Divide both sides by 3
3/3y = 2/3x
Dividing by 3 undoes the multiplication by 3
y = 2/3x
