3% as a fraction
a- 1/50
b-3/100
c-30/100
Answer:
b
Step-by-step explanation:
Answer:
The answer is b
Step-by-step explanation:
100 represents a whole amount so the numerator would be 3 over 100 because it is 3% out of a total of 100.

Answer:
y = 12 x = 12√2 z = 12√3
Step-by-step explanation:
The 45° triangle will also have a height of y so....
y² + y² = x² 2y² = x² y² = x²/2 y = √(x²/2)
The 30° triangle
y² + z² = 24² y² = 24² - z² y = √(24² - z²)
sin 30 = y/24 1/2 = y/24 y = 12
y² = x²/2
12² = x²/2²
2(144) = x² x = √(288) x = 12√2
y² + z² = 24²
z² = 24² - y²
z² = 24² - 12²
z² = 576 - 144
z² = 432
= √(16·9·3)
z = 4·3√3
z = 12√3
y² + z² = 24²
12² + (12√3)² = 24²
144 + 144·3 = 576
2y² = x²
2(12)² = x²
288 = (12√2) = 144·2 = 288
The histogram below shows the number of push-ups the students in Hayley's class can do.
Select all of the true statements about the data.
The majority of students can do more than 15 push-ups.
The data distribution is skewed to the right.
More students did 6-10 push-ups than 11-15 push-ups.
The students in Hayley's class can do between 1 and 25 push-ups.
The data distribution is skewed to the left.
300 is what percent less than 599
Answer:
59.8%
Step-by-step explanation:
599 - 300 = 299. Now we need to find the percentage 299 is of 500.
299 / 500 = 0.598
0.598 as a percent is 59.8%.
Answer: 59.8%
Hope this helps!
Name a pair of lines that are perpendicular
Answer:
Two distinct lines intersecting each other at 90° or a right angle are called perpendicular lines. Here, AB is perpendicular to XY because AB and XY intersect each other at 90°. The two lines are parallel and do not intersect each other. They can never be perpendicular to each other.

Josh cycled 8 laps on a bicycle path surrounding a lake. Each lap was the same length. If he cycled a total of 26.4mi, what was the length of each lap around the lake? Write your answer in feet. Use the table of conversion facts as necessary, and do not round your answer. ft
Answer:
The length of each lap around the lake was of 3.3 miles.
Step-by-step explanation:
Given that Josh cycled 8 laps on a bicycle path surrounding a lake, and each lap was the same length, to determine what was the length of each lap around the lake if he cycled a total of 26.4 miles, the following calculation must be performed:
26.4 / 8 = X
3.3 = X
Thus, the length of each lap around the lake was 3.3 miles.

Plz give the answer for 8th and 9th question
Answer:
8. 8/9 is not the multiplicative inverse of –1⅛
9. 0.3 is the multiplicative inverse of 3⅓
Step-by-step explanation:
To answer the above questions, we must understand the meaning of multiplicative inverse. This is illustrated below:
Let y be the number.
The multiplicative inverse of y denoted by y¯¹ (or 1/y) when multiplied with y will give an identity of 1 i.e
y × y¯¹ = 1
Or
y × 1/y = 1
Now, let us answer the questions given above by calculating the multiplicative inverse.
8. The number (y) = –1⅛ = –9/8
Multiplicative inverse (y¯¹) =?
y × y¯¹ = 1
–9/8 × y¯¹ = 1
Divide both side by –9/8
y¯¹ = 1 ÷ –9/8
y¯¹ = 1 × –8/9
y¯¹ = –8/9
Thus, 8/9 is not the multiplicative inverse of –1⅛
9. The number (y) = 3⅓ = 10/3
Multiplicative inverse (y¯¹) =?
y × y¯¹ = 1
10/3 × y¯¹ = 1
Divide both side by 10/3
y¯¹ = 1 ÷ 10/3
y¯¹ = 1 × 3/10
y¯¹ = 3/10
y¯¹ = 0.3
Thus, 0.3 is the multiplicative inverse of 3⅓.
At a party, if 1/5 of one sheet
cake is uneaten and Tom eats
1/6 of the uneaten cake, what
fraction of the original cake
did Tom eat?
Answer:
Step-by-step explanation:
He eats 1/6 or 1/5 of the original cake.
All you need to do to get the answer is multiply the denominators.
1/5 * 1/6 = 1/30
If there was something in the numerators. you would multiply them too.
So suppose the two fractions were 3/5 and 2/7
The answer would be 3 * 2 / 5 * 7 = 6 / 35
General rule
When multiplying two fractions, multiply numerator * numerator / (denominator * denominator).
One number is five less than a second number. Five times the first is 2 more than 2 times the second. Find the numbers.

what are the statements
Step-by-step explanation:
DeVondrea stacked 2
quarters and a nickel on top
of each other. What is the
thickness of the stack of
coins?
Answer:
Step-by-step explanation:
Number of nickels = $1 * 1 nickel/$0.05 = 20 nickels
Thickness of 20 nickels = 20 nickels * 1.95 mm = 39 mm
Let's do the same for the quarters. Each quarter is worth $0.25.
Number of quarters = $1 * 1 quarter/$0.25 = 4 quarters
Thickness of 4 quarters = 4 quarters * 1.75 mm = 7 mm
Find the ratio of the two:
39 mm/7 mm = 5.57

Bob took out a 5 year loan for $4000 and paid 3% annual simple interest
Bill took out a 4 year loan for $4000 and paid 5% annual simple interest
What is the sum of amounts of interest bob and bill paid for their loans
find the missing length
Answer:
PQ=36
Step-by-step explanation:
If the triangles are similar, then they must have a common ratio between them.
RQ corresponds with CB, so [tex]\frac{84}{18}=\frac{14}{3}[/tex]
If the ratio is [tex]\frac{14}{3}[/tex], then [tex]\frac{168}{\frac{14}{3}}=36[/tex], so PQ=36.

In 2011, 51% of cell phone owners in a country reported that their cell phone was a smartphone. The following year, the researchers wanted to test to see if the proportion of cell phone owners in that country who have a smartphone has increased over time at the a = 0.05 level. They surveyed a random sample of 934 cell phone owners in that country and found that 501 of them had a smartphone. They conducted a significance test and found the p-value to be 0.0532. Is there convincing evidence that the proportion of cell phone owners in that country who have a smartphone has increased over time?
Answer:
The calculated value Z = 1.5950 < 1.96 at 0.05 level of significance
The null hypothesis is accepted at a 0.05 level of significance
The proportion of cell phone owners in that country who have a smartphone has not increased over time
Step-by-step explanation:
Step(i):-
Given that the random sample size 'n' = 934
Given that the population proportion P = 0.51
Q= 1-P
Q = 1- 0.51 = 0.49
The sample proportion
[tex]p = \frac{x}{n} = \frac{501}{934} = 0.5364[/tex]
Level of significance = 0.05
Critical value Z₀.₀₅ = 1.96
Step(ii):-
Null hypothesis: P < 0.51
Alternative Hypothesis : P > 0.51
Test statistic
[tex]Z = \frac{p-P}{\sqrt{\frac{PQ}{n} } }[/tex]
[tex]Z = \frac{0.536-0.51}{\sqrt{\frac{0.51 x 0.49}{934} } }[/tex]
Z = 1.5950
Final answer:-
Given that P-value 0. 0532
P-value > 0.05
Rejected Alternative Hypothesis and accepted null hypothesis
( OR)
The calculated value Z = 1.5950 < 1.96 at 0.05 level of significance
The null hypothesis is accepted at a 0.05 level of significance
The proportion of cell phone owners in that country who have a smartphone has not increased over time
