Answer:
Rachel worked for [tex]3\frac{2}{3}[/tex] hours
Step-by-step explanation:
See comment for complete question
Given
Let
[tex]D = Dominic[/tex]
[tex]R = Rachel[/tex]
So:
[tex]D = 2\frac{3}{4}[/tex]
and
[tex]R =1\frac{1}{3}[/tex] as long as D
Required
Determine the number of hours spent by Rachel
This implies that:
[tex]R =1\frac{1}{3}[/tex] as long as D
Rewrite as:
[tex]R =1\frac{1}{3} * D[/tex]
Substitute: [tex]D = 2\frac{3}{4}[/tex]
[tex]R =1\frac{1}{3} * 2\frac{3}{4}[/tex]
Express as improper fraction
[tex]R =\frac{4}{3} * \frac{11}{4}[/tex]
This gives:
[tex]R =\frac{1}{3} * 11[/tex]
[tex]R =\frac{11}{3}[/tex]
Express as mixed numbers
[tex]R =3\frac{2}{3}[/tex]
Hence, Rachel worked for [tex]3\frac{2}{3}[/tex] hours

Tapanga drew triangle XYZ on her paper the measure of angle X was 80 degrees angle y was congruent to angle Z what was measure of angle Z
Answer:
50degrees
Step-by-step explanation:
The sum of angle in the triangle XYZ is 180degrees, hence;
<X + <Y + <Z = 180
Given
m<X = 80degree
m<Y = m<Z
Required
m<Z
Substitute the given angle
80 + m<Z + m<Z = 180
80 + 2m<Z = 180
2m<Z = 180 - 80
2m<Z = 100
m<Z = 100/2
m<Z = 50degrees
Hence the measure of angle Z is 50degrees

The data show the times (in minutes) spent fishing before getting a bite. 12, 25, 28, 20, 18, 16, 22, 30 What fraction of the times are less than or equal to 17 minutes?
Answer:
1/4
Step-by-step explanation:
Firstly, we need the numbers that are less than or equal to 17 minutes
These numbers from the data set are;
12 and 16
The count of numbers is;
8
so the fraction we need is simply 2/8
and that is 1/4

Step-by-step explanation:
What single percentage change is equivalent to a 11% decrease followed by a 15% decrease?
Answer:
Read the explanation to find your answer.
Step-by-step explanation;
First, work out the difference (decrease) between the two numbers you are comparing. Next, divide the decrease by the original number and multiply the answer by 100.
Answer:
The answer is 75.65%.
Step-by-step explanation:
Since we are decreasing the percentages, we will first take 100 and subtract 11% from it, which is 89%. Now take 15% and turn it into decimal form, and we get 0.15. Then multiply 0.15 by 89 and we get 13.35. Now we have our number 13.35, we will subtract 89 from 13.35, and we get 75.65%. Therefore, the answer is 75.65%.
Three pairs of shoes cost $108. If each pair costs the same, how much does each one cost?
A.$32
B.$34
C.$36
D.$38
Answer:
C: 36
Step-by-step explanation:
There are 3 pairs of shoes. They all cost the same. Since these shoes add up to 108 dollars, they basically multiply by three to get to 108. (3x=108) If you want to figure out the cost of one shoe you just have to reverse the process by using division. So just do simple division by dividing 108 by three (108/3=x) and there is your answer, 36.

The ratio of mango ice cream to strawberry ice-cream is 1:4. Total no. of ice cream is 30. What is the no. of mango ice-cream?
Step-by-step explanation:
let the ratio of ice cream be x&4x
total number of ice cream =30
now,
x+4x=30
5x=30
x=30/5
x=6
mango ice cream=x=6
strawberry ice cream=4x=4×6=24
hope it helps.
Answer:
6 !
Step-by-step explanation:
mango = x
strwberry = 4x
total = x+4x = 5x = 30
5x= 30
x= 30/5 = 6
mango = x= 6
strwberry = 4x = 24
I hope im right!

Answer:
∠x = 36°
Step-by-step explanation:
∠a = 180° - 106° = 74°
=> ∠b = 180° - 40° - 74° = 66°
=> ∠c = 180° - 66° = 114°
=> ∠d = 180° - 114° - 30° = 36°
=> ∠x = ∠d = 36°

He sum of seven interior angle measurements in an octagon equal 845º. What is the angle measurement of the 8th angle?
Answer: [tex]235^{\circ}[/tex]
Step-by-step explanation:
Given
The Sum of the seven interior angles of an octagon is [tex]845^{\circ}[/tex]
for a Polygon, the sum of the interior angles is given by [tex](n-2)180^{\circ}[/tex]
for octagon, n=8
The Sum of interior angles is [tex](8-2)360^{\circ}=1080^{\circ}[/tex]
Suppose the eighth angle be [tex]x[/tex]
[tex]\therefore x+845=1080\\\Rightarrow x=235^{\circ}[/tex]
The [tex]8^{th}[/tex] angle is [tex]235^{\circ}[/tex]
Find the length of each arc. Round your answer to the nearest tenth
Answer:
D
Step-by-step explanation:
The arc length is calculated as
arc = circumference of circle × fraction of circle
= 2πr × [tex]\frac{\frac{\pi }{6} }{2\pi }[/tex] ( cancel the 2π )
= 12 × [tex]\frac{\pi }{6}[/tex] = 2π ≈ 6.3 ( to the nearest tenth ) → D

The value of y varies directly with x. When y=75, x= 0.5. What is the value of y when x is 2.25?
Even though I pulled up the work, I still don’t know what to do ♀️
Answer:
y=337.5 when x = 2 1/4
Step-by-step explanation:
Well first we want to know what's the function here
How do we get y to be 75 if x is .5?
75/.5 is 150
so can we say the function is 150x=y
Now lets plug
2 1/4 or 2.25 for x
2.25*150 = 337.5
y=337.5 when x = 2 1/4

A city council consists of sevenseven Democrats and eighteight Republicans. If a committee of fivefive people is selected, find the probability of selecting twotwo Democrats and threethree Republicans.
Answer:
The probability of selecting two Democrats and three Republicans is 10.7%.
Step-by-step explanation:
Given that a city council consists of seven Democrats and eight Republicans, if a committee of five people is selected, to find the probability of selecting two Democrats and three Republicans the following calculation must be performed:
7 = 100
2 = X
2 x 100/7 = X
28.57 = X
8 = 100
3 = X
3 x 100/8 = X
37.5 = X
0.2857 x 0.375 = X
0.107 = X
0.107 x 100 = 10.7
Therefore, the probability of selecting two Democrats and three Republicans is 10.7%.
