MINH:

subtract what was actually biked from his goal

= 125 1/2 - 125 1/6

convert to like denominators

= 125 3/6 - 125 1/6

= 2/6

simplify

= 1/3 or 0.3333333

PJ:

= 120 1/4 - 120

= 1/4 or 0.25

ANSWER: PJ came closer to his goal because 1/4 (or 0.25) is closer to zero which makes it a smaller number than 1/3 (or 0.33).

Hope this helps! :)

PJ was closer because he was .25 away from his goal and Minh was .16666 away from his goal.

Question

7r. r represents a fraction which value of r makes the expression equal a number less than 7? 4/4 or 4/3 or 4/5 or 4/1

Solution 1

Multiply 7 by each of the fractions to find the solution that is less than 7

= 7 * 4/4

= (7*4)/4

= 28/4

= 7

= 7 * 4/3

= (7*4)/3

= 28/3

= 9 1/3

= 7 * 4/5

= (7*4)/5

= 28/5

= 5 3/5

= 7 * 4/1

= (7*4)/1

= 28/1

= 28

ANSWER: The fraction that gives a solution less than 7 is 4/5. 4/5 multiplied by 7 is 5 3/5.

Hope this helps! :)

Question

Elaina ran 2.52 miles on Monday, 4.53 miles on Wednesday, and 3.45 miles on Saturday. What percent of the total miles did Elaina run on Monday?

Solution 1

Add all the miles

2.52+4.53+3.45=10.5 miles

(Monday/total miles)*100%

=(2.52/10.2)= 24%

2.52+4.53+3.45=10.5 miles

(Monday/total miles)*100%

=(2.52/10.2)= 24%

Question

Find 2r2 + 3s3 − r2 + 4t2 − r2 if r = −2, s = −3, and t = 5.

Solution 1

2 x -2 x 2 = -8

+ 3 x -3 x 3 = -9

- (-2) x 2 = -4

+ 4 x 5 x 2 = 40

- (-2) x 2 = -4

So then -8 + (-9) - (-4) + 40 - (-4) = 31

Glad I can help :)

+ 3 x -3 x 3 = -9

- (-2) x 2 = -4

+ 4 x 5 x 2 = 40

- (-2) x 2 = -4

So then -8 + (-9) - (-4) + 40 - (-4) = 31

Glad I can help :)

Solution 2

The answer to 556 * 34 is 18,904.

Question

What is the inequality of 6x-4<8?

Solution 1

6x - 4 < 8

Add 4 to both sides:

6x < 12

Divide both sides by 6:

x < 2

**Answer: x < 2**

Add 4 to both sides:

6x < 12

Divide both sides by 6:

x < 2

Question

there are 200 end of the year school dance tickets students who have perfect attendance are able to presage them in advance if 18 tickets were purchased in advance then what percent of the were in advance

Solution 1

182 is the answers

Question

The area of a rectangular photograph is 35 square inches. If the width of the photo is 5 inches, how tall is the photo

Solution 1

7, 7*5 is 35. Answer is 7 inches.

Solution 2

First, do inverse operations

5 x ? = 35 >>> 35 / 5 = 7

Solution - The photo was 7 inches tall

Post brainliest if this helped :D

5 x ? = 35 >>> 35 / 5 = 7

Solution - The photo was 7 inches tall

Post brainliest if this helped :D

Question

a chemist has 5 1/10 kg of calcium. if she uses 0.15 kg of the compound each time she performs an experiment, for how many experiments will her supply last?

Solution 1

5 times 1/10 is 5/10 or 1/2 of a kg. This equals 0.5 kg. You can do 3 experiments (use up until 4.5 kg)

Question

A remote-control airplane descends at a rate of 2 feet per second. After 3 seconds it is 67 feet above the ground. Write the equation in point-slope form that models the situation. Then, find the height of the plane after 8 seconds.

Solution 1

A] A remote-control airplane descends at a rate of 2 feet per second. After 3 seconds it is 67 feet above the ground.

the point slope equation will be given as follows:

y-y1=m(x-x1)

where:

slope,m=2 ft/sec

(x1,y1)=(3,67)

thus plugging in the values in the formula, we obtain the point slope equation as follow:

y-67=2(x-3)

Answer:

y-67=2(x-3)

b]The height of the plane after 8 seconds will be:

x=8 sec

but:

y-67=2(x-3)

substituting x=8 we get:

y-67=2(8-3)

y-67=2(5)

y=10+67

y=77

thus the height after 8 seconds is 77 ft

the point slope equation will be given as follows:

y-y1=m(x-x1)

where:

slope,m=2 ft/sec

(x1,y1)=(3,67)

thus plugging in the values in the formula, we obtain the point slope equation as follow:

y-67=2(x-3)

Answer:

y-67=2(x-3)

b]The height of the plane after 8 seconds will be:

x=8 sec

but:

y-67=2(x-3)

substituting x=8 we get:

y-67=2(8-3)

y-67=2(5)

y=10+67

y=77

thus the height after 8 seconds is 77 ft

Question

there are 200 end of the school year dance tickets available students who have perfect attendance are able to personage them in advance if 18 tickets were purchased in advance then what percent of the tickets were purchased in advance

Solution 1

The **percentage **of the** tickets** for the dance that were purchased in **advance** is **9%.**

**Percentage** is the fraction of an amount that is expressed as a number out of hundred. The sign used to represent **percentage **is %.

**Percent **of **advance tickets** bought = (number of advance tickets / total number of tickets) x 100

(18 / 200) x 100 = **9%**

To learn more about **percentages,** please check: brainly.com/question/25764815

Solution 2

9 percent because 18 divided by 200 is 0.09 or 9 percent.
