2 is the answer of the above

Answer 2

Answer:

x=5

Step-by-step explanation:

We know that corresponding sides will have the same angles. In this case it's 12 and 12+3=15. That means that larger triangle is 15/12=5/4=1.25 times larger.

So we apply that for 3x+1 as well.

1.25(3x+1)=4x

3.75x+1.25=4x

.25x=1.25

x=5

Name the segment parallel to the given segment for #2

Answers

Answer:

YZ is parallel to RT

RS is parallel to XZ

XY is parallel to TS

Step-by-step explanation:

The answer is self-explanatory if you look at the picture and the segments listed as parallel - running side by side. Hope this helps and all the answers are right. Just checked the score on the test and these were right.

The parallel line segment will be YZ || RT, RS || XZ, and XY || TS.

What is the triangle?

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.

In math, equal lines can be characterized as two lines in the very plane that are at equivalent separation from one another and never meet.

The length of a line portion can be estimated either in metric units like millimeters, and centimeters, or in standard units like feet or inches.

The line segment YZ is parallel to RT.

The line segment RS is parallel to XZ.

The line segment XY is parallel to TS.

The parallel line segment will be YZ || RT, RS || XZ, and XY || TS.

During each of the past three months, Tyler grew
by the following amounts: 1/8in., 3/16in., and 1/4in.
What is Tyler's total amount of growth over these
three months?
Answer with supporting work:

Answers

first you have to make all the fractions have a common denominator to add them so since 3/16 is the largest denominator you have to convert the others to have the denominator of 16. 1/8 = 2/16. 1/4 = 4/16. so if you add the numerators that’s 3 + 2 + 4 = 9. so the answer would be 9/16, and this cannot be simplified so it is your final answer:)

Donte ordered the plans shown to build a skateboard ramp. Each unit represents one foot. He wants to keep the same slope of the ramp and extend the base of the triangle three feet. How tall will the ramp be

Answers

Answer:

3 feet

Step-by-step explanation:

The slope of line shows the steepness of that line. It is the ratio of the change in vertical distance to the change in horizontal distance.

The slope of a line passing through points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] on the coordinate plane is:

[tex]slope=\frac{change\ in\ y}{change\ in\ x}=\frac{y_2-y_1}{x_2-x_1}[/tex]

From the diagram of the ramp, we can see that:

The ramp passes through the point (0,0) and (6, 2). Therefore the slope is:

[tex]slope=\frac{2-0}{6-0}=\frac{1}{3}[/tex]

The base is at 6 ft tall, if we extend the base by 3 units, the base would be 9 ft (6 + 3). The new height would be:

height = slope * base = (1/3) * 9 = 3 feet

If the base is extended by 3 feet, the tall would be 3 feet tall.

HEL MEEEE

Answers

Answer:

A esta así no puedo xd ._.

Total Pens, owned by all students between all of them = 360

Percentage wise calculation of Pens

Total children = 360
Students having one pen = 95% of 360 = 18

Remaining 95% = 360 - 18 = 342

Half of remaining ie 342 = 171, have two pens

Other half of remaining ie 171 have no pens

Total pens, all children have between all of them = Summation (number of students x number of pens)

What is the adoption cost?

Adoption cost in the given problem is the money spent in maintenance, feeding, and other expenses in order to adopt a pet.

"Adoption costs more money than buying a pet" is an incorrect statement because if we extract the conclusion combinedly from statements 2 and 3, it is clear that adoption cost is in the range of $50 and $500 in the case of a shelter animal while an animal from a pet store typically costs at least $1,000.

"Pet stores are more expensive than breeders", this is an incorrect statement because in the third paragraph it is mentioned that "an animal from a pet store typically costs at least $1,000. Breeders are even more expensive."

"It is more expensive to buy a pet than it is to adopt" is a correct statement because in the fourth paragraph it is mentioned that "adopting pets from shelters is the logical choice because shelter animals are less expensive than those bought from pet stores or breeders."

"Cats are more expensive than dogs" is an incorrect statement because in the second paragraph it s mentioned, "adopting a dog or a cat from a shelter usually costs between $50 and $500." There has not been discussed anything about the individual adoption costs for each.

Therefore, Statement 1 is incorrect.

Statement 2 is incorrect.

Statement 3 is correct.

Statement 4 is incorrect.

Answer:

Answer:

a = 30

b = 15

c = 3

d = 30

e = 10

f = 20

Step-by-step explanation:

60 deg and a + 30 are alt int <S and congruent

a + 30 = 60

a = 30

a + 30 and a + 2b are corresponding angles and congruent

a + 2b = a + 30

2b = 30

b = 15

a + 2b and 5b - 5c are vertical angles and congruent

5b - 5c = a + 2b

5(15) - 5c = 30 + 2(15)

75 - 5c = 30 + 30

75 - 5c = 60

-5c = -15

c = 3

a + 2b and 10c + d are corresponding angles and congruent

10c + d = a + 2b

10(3) + d = 30 + 2(15)

d + 30 = 60

d = 30

5b - 5c and 2d + 6e are supplementary and add to 180

5b - 5c + 2d + 6e = 180

5(15) - 5(3) + 2(30) + 6e = 180

75 - 15 + 60 + 6e = 180

6e + 120 = 180

6e = 60

e = 10

2d + 6e and 4f + 4e are alt int angles and congruent.

4f + 4e = 2d + 6e

4f + 4(10) + 2(30) + 6(10)

4f + 40 = 60 + 60

4f + 40 = 120

4f = 80

f = 20
