Complete question :
Ray starts walking to school at a rate of 2 mi/h. Ten minutes later, his sister runs after him with his lunch, averaging 6mi/h. Determine take it takes for sister to catch up
Answer:
5 minutes
Step-by-step explanation:
Ray's rate = 2mi/ hr
Time walked before sister starts = 10 minutes = (10/60) = 0.16667 hours
Hence, distance already covered = (rate * time) = (2 * 0.16667) = 0.3333 miles
To catchup :
Let t = Time taken to catch ; At t, distance covered must be the same ; thus ;
0.3333 + (2 * t) = 6 * t
0.3333 + 2t = 6t
0.3333 = 6t - 2t
0.3333 = 4t
t = 0.3333 / 4
t = 0.0833333 hours
t = 0.0833333 * 60 = 5 minutes
Answer question 3. Please show you’re work.
Answer:
a. x = 11
b. 1 = 38
c . 2 = 55
Step-by-step explanation:
Here, we want to find the values of the marked angles
The two add up to give a right angle
Thus;
5x + 3x + 2 = 90
8x = 90-2
8x = 88
x = 88/8
x = 11
m1 = 3x + 5
substitute for x
m1 = 3(11) + 5 = 38
m2 = 5x
= 5(11) = 55

A car travels 2 5/8
miles in 3 1/2
minutes at a constant speed. Which equation represents the distance, d, that the car travels in m minutes?
Ad = 0.75m
B. d=14 m
C. d = 3.5m
D. d = 2.625m
Answer:
A. d = 0.75m.
Step-by-step explanation:
If, for 3 1/2 minutes (3.5 minutes) the car travels 2 5/8 miles (2.625 miles),
Then in m minutes the car will travel d miles
d = (2.625*m)÷ 3.5
d = 0.75m
Which is option A

Answer:
for the first picture, she cleans 30 windows
the second picture is 52/100 :)
Answer:
It's B for the first one.
For the second one, it is C
Step-by-step explanation:
30 * 0.3 = 9
So 30% of 30 is 9. She did 9 windows.
0.52 = 52/100
It's 52/100 because 0.52 = 52%. 52% then equals 52/100.
52/100 = 13/25
So the answer is 13/25

what will be the new coordinate of vertex b if the triangle is dilated with a center at the origin by a scale factor of 1/3
Answer:
6 , 3
Step-by-step explanation:
your welcome
The new coordinate of vertex B if the triangle is dilated with a center at the origin by a scale factor of 1/3 is (1,2) and this can be determined by using the given data.
Given :
Dilation Factor = 1/3Points - A(-2,2), B(3,6), and C(1,-2)After the dilation of 1/3 the coordinate of the triangle becomes:
[tex]\rm A(-2,2) \to A'(-2\times \dfrac{1}{3},2\times \dfrac{1}{3}) = A'\left(\dfrac{-2}{3},\dfrac{2}{3}\right)[/tex]
[tex]\rm B(3,6) \to B'(3\times \dfrac{1}{3},6\times \dfrac{1}{3}) = B'\left(1,2)[/tex]
[tex]\rm C(1,-2) \to C'(1\times \dfrac{1}{3},-2\times \dfrac{1}{3}) = C'\left(\dfrac{1}{3},\dfrac{-2}{3}\right)[/tex]
The new coordinate of vertex B if the triangle is dilated with a center at the origin by a scale factor of 1/3 is (1,2).

People who understand please reply
a = 49.0 rounded to 1 DP
b= 7.62 rounded to 2 DP
Find the minimum of a - b
Answer:
The minimum of a - b is 41.325
Step-by-step explanation:
Let us solve the question using upper and lower boundaries
∵ a = 49.0 rounded to 1 decimal place
∵ 1 decimal place means 0.1
→ Divide 0.1 by 2
∵ 0.1 ÷ 2 = 0.05
→ Add 0.05 to the rounded number to get the upper boundary
∵ 49.0 + 0.05 = 49.05
∴ The upper boundary = 49.05
→ Subtract 0.05 from the rounded number to get the lower boundary
∵ 49.0 - 0.05 = 48.95
∴ The lower boundary = 48.95
∴ The range of a is 48.95 ≤ a < 49.05
∵ b = 7.62 rounded to 2 decimal places
∵ 2 decimal place means 0.10
→ Divide 0.01 by 2
∵ 0.01 ÷ 2 = 0.005
→ Add 0.005 to the rounded number to get the upper boundary
∵ 7.62 + 0.005 = 7.625
∴ The upper boundary = 7.625
→ Subtract 0.005 from the rounded number to get the lower boundary
∵ 7.62 - 0.005 = 7.615
∴ The lower boundary = 7.615
∴ The range of b is 7.615 ≤ b < 7.625
To find the minimum value of a - b, use the smallest value of a and the greatest value of b
∵ The minimum of a - b = lower boundary of a - upper boundary of b
∴ The minimum of a - b = 48.95 - 7.625
∴ The minimum of a - b = 41.325
∴ The minimum of a - b is 41.325

Answer:
m∠7 = 63 degrees
m∠8 = 117 degrees
m∠9 = 63 degrees
Step-by-step explanation:
When two lines intersect at a point, then they formed 2 pairs of vertically opposite angles and 4 pairs of linear angles
The vertically opposite angles are equal in measuresThe linear angles have a sum of 180°In the given figure
∵ There are two lines intersected at a point
∴ The angle of measure 117° and ∠8 are vertically opposite angles
∴ ∠7 and ∠9 are vertically opposite angles
∴ The angle of measure 117° and ∠7 are linear angles
∵ The vertically opposite angles are equal in measures
∴ The angle of measure 117° and ∠8 are equal in measures
∴ m∠8 = 117°
∵ The sum of the measures of the linear angles is 180°
∴ m∠7 + 117° = 180°
→ Subtract 118 from both sides
∵ m∠7 + 117 - 117 = 180 - 117
∴ m∠7 = 63°
∵ m∠7 = m∠9 ⇒ proved up
∴ m∠9 = 63°

Write a system of equations to describe the situation below, solve using any method, and fill in the blanks.
Norma is looking for a job cutting hair. One option is self-employment at The Seaside Salon, where she would pay $534 per month to rent a station and keep all of her earnings. Another option is to work at a franchise, where she would just have to pay the salon $3 for every haircut. If she performed a certain number of haircuts every month, the amount paid to either salon would be the same. How many haircuts would that be? How much would Norma pay?
If Norma performed__________ haircuts in a month, she would pay $____________ to either salon.
Answer:
If Norma performed 178 haircuts in a month, she would pay $534 to either salon
Step-by-step explanation:
Saloon 1:
Cost of saloon 1 = $534
Saloon 2:
Cost of saloon 2 = 3h
Where,
h = number of haircut
Equate the cost of renting either saloon
534 = 3h
h = 534 / 3
h = 178 hair cut
If Norma performed 178 haircuts in a month, she would pay $534 to either salon.
