Frazer scores 70% in a spelling test with 20 questions. How many did he get right? Show me your work.

1 answer:

4 0

Fraser got 14 questions right

questions correct 70/5 = 14
—— ——
total questions 100/5 = 20

therefore he got 14 questions right

you divide 100 by 5 because percents are always out of 100 and that gets you 20 which is how many questions the spelling bee had

then you do the same to the top (divide by 5) and get 14

14/20 questions were answered right
70% of the questions were correct

Raul drove 80 miles. This represents 50% of his entire trip. What is the total number of miles in Raul's trip?

Dafna11 [192]

If 80 miles is 50% of his trip, then you know that 80 miles is only HALF of his entire trip. To get the distance Raul traveled in total, simply double the 80 miles. This would be 160 miles.
Raul traveled a total of 160 miles in his trip.

If you were given the data set $s $10, $10, $12, $13, $15, which measure of central

Katarina [22]

Answer: Mode

<u>Step-by-step explanation:</u>

The given data set is: 10, 10, 12, 13, 15

Mean is the average - find the sum of the data set and divide by the number of terms in the set: $\dfrac{10+10+12+13+15}{5} =\dfrac{60}{5}=12$

Mean = 12

Median is the middle term (when the data set is ordered from least to greatest).

Median = 12

Mode is the term that appears the most.

Mode = 10

Since you want to show that the prices are low, you would choose the lowest value. 10 is lower than 12, so the Mode is lower than either the Mean or the Median.

state which basic Property of addition or multiplication justifies truth of the mathematical expressions 0+7y+2=7y+2

dlinn [17]

The given equation is:

0 + 7y + 2 = 7y + 2

This equation is showing that addition of 0 leaves the expression unchanged. 0 is known as the Additive Identity this means if we add or subtract 0 from any expression, number or equation the result won't be changed.

Therefore, the equation satisfied the property of Additive Identity of Real Numbers.

getting home from trick or treat celia and emma counted their candies. half of celias candies is equal to 2/3 of emmas candies.

blagie [28]

Candies with celias and emmas is 60 and 45 respectively.

<u>Solution:</u>

Given, Getting home from trick or treat celia and emma counted their candies. Half of celias candies is equal to 2/3 of emmas candies.

They had a total of 105 candies altogether.

We have to find how many candies did each of them have.

Let the number of candies with celias be n, then number of candies with emma will be 105 – n.

Now according to given condition.

$\begin{array}{l}{\frac{1}{2} \times \text { celias candies count }=\frac{2}{3} \times \text { emmas candies count }} \\\\ {\rightarrow \frac{1}{2} \times n=\frac{2}{3} \times(105-n)} \\\\ {\rightarrow 3 \times n=2 \times 2 \times(105-n)} \\\\ {\rightarrow 3 \times n=2 \times 2 \times(105-n)} \\\\ {\rightarrow 3 n=4(105-n)} \\\\ {\quad \rightarrow 3 n=420-4 n} \\\\ {\rightarrow 3 n=420-4 n} \\\\ {\rightarrow 3 n+4 n=420} \\\\ {\rightarrow 7 n=7 \times 60} \\\\ {\rightarrow n=60}\end{array}$

Hence, candies with celias and emmas is 60 and 45 respectively.
