Raheem's entire workout consisted of 15 minutes of warm-up exercises, 30 minutes of lifting weights,and 45 minutes on the treadmill.What is the ratio of the number of minutes he lifted weights to the total number of minutes of his entire workout? a. 1:1. b. 1:3. c.1:9. d.3:10
Answer:
b
Step-by-step explanation:
Time taken for the total workout = 15 + 30 + 45 = 90 minutes
Time taken for lifting weight : total time = 30 : 90
= 1 : 3

Find the value of x that makes lines u and v parallel, answer needed
Given:
u and v are parallel lines.
To find:
The value of x.
Solution:
If a transversal line intersect the two parallel lines, then
(1) Corresponding angles are congruent.
(2) Same sides interior angles are supplementary angles and their sum is 180 degrees.
15.
[tex]23x-2=90[/tex] (Corresponding angles)
[tex]23x=90+2[/tex]
[tex]x=\dfrac{92}{23}[/tex]
[tex]x=4[/tex]
Therefore, the value of x is 4.
16.
[tex](x+106)+(x+86)=180[/tex] (Same sided interior angles)
[tex]2x+192=180[/tex]
[tex]2x=180-192[/tex]
[tex]2x=-12[/tex]
Divide both sides by 2.
[tex]x=\dfrac{-12}{2}[/tex]
[tex]x=-6[/tex]
Therefore, the value of x is -6.

if 22 of the 92 people who swim at the YMCA are children, what is the ratio of adults to children who swim at the YMCA? Write the ratio in lowest terms as a fraction or
with a colon.
Answer:
35:11
Step-by-step explanation:
1. Subtract 22 children from 92 total people to get the number of adults.
92 - 22 = 70 adults
2. recognize that the first number in your ratio will be for the adults.
3. Write out ratio of adults to children
70:22
4. Simplify (both denominator and numerator are divisible by 2)
35:11

Clarence made a diagram to compare codominance and incomplete dominance. Which label belongs in the area marked Y? Neither allele is dominant. An intermediate phenotype is expressed in offspring. One allele is dominant over the other. Both dominant alleles are fully expressed in offspring.
Answer:
The correct answer is both dominant alleles are fully expressed in offspring.
In the incomplete dominance inheritance, one allele is not completely expressed over its paired allele and forms an intermediate trait, whereas in co-dominance, both the alleles express completely resulting into a new phenotype. For example AB blood group in humans.
In the given question Y is the intersection of co-dominance set and incomplete dominance set. Thus, the area Y may have one dominant allele from co-dominance and one allele which is not completely dominant from incomplete dominance.
Therefore, the label to marked area Y may be - both dominant alleles are fully expressed in offspring.

Solve 3b−42=c, for b.
Answer:
b=1/3c+14
Step-by-step explanation:
Let's solve for b.
3b−42=c
Step 1: Add 42 to both sides.
3b−42+42=c+42
3b=c+42
Step 2: Divide both sides by 3.
3b
3
=
c+42
3
hope this helps
Answer:
b= 1 /3 c+14
Step-by-step explanation:
Add 42 to both sides.
3b−42+42=c+42
3b=c+42
Divide both sides by 3.
3b/3=c+42/3
b=1/3c+14

Answer:
x=36
Step-by-step explanation:
2x+2x+x+4-2-2=180
Combine Like Terms
5x=180
Divide
x=36
Answer:
we know that if we add all of the angles it adds up to 180 degrees
Step-by-step explanation:
so 180=(x-2)+(2x+4)+(2x-2)
combine like terms
180=5x
divide by 5 to isolate variable
x=36
If you need to find for an angle apply the x value into the given equation

Brendon is building a clubhouse where 11 inch on the plans is equivalent to 88 inches on the actual clubhouse.
If the clubhouse is to be 160 inches wide, what will the width be on the plans?
Round answer to the nearest hundredth if necessary.
20
160/8=20
88/8=11
i hope this one helps !!
Answer:
20,020 in. on the plans
Step-by-step explanation:
To get from 11 in. to 88 in. (from plans to real life), you multiply by 8.
Therefore, to get from 160,160 to ?? (from real-life to plans), you would divide by 8.
160,160 / 8 = 20,020
To check, you can multiply 20,020 by 8 to go from plans to real-life measurements; 20,020 • 8 = 160,160)
Simplify:
4y + (2y – 4)
