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
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.
A farmer planted 1890 plants in a field in rows each having 63 plants. A certain type of worm destroyed 21 plants in each row. How many plants were not destroyed by the worms?
Answer:
1260 plants remaining
Step-by-step explanation:
63-21=42 (number of plants not destroyed)
1890/63=30 rows of plants
30x42=1260 plants remaining
n the diagram, the measure of angle 9 is 85°.
4 lines intersect to form 16 angles. The angles created, clockwise from top left are 1, 2, 3, 4; 5, 6, 7, 8; 9, 10, 11, 12; 13, 14, 15, 16.
Which angle must also measure 85°?
Angle2
Angle5
Angle11
Angle12
Answer:
The real answer is angle 5
Step-by-step explanation:
The angle 11 must measure the angle 85. The correct option is C.
What are lines and angles?An infinitely long row of evenly spaced dots that extends in both directions makes up a line. Its length is the only dimension it has. An illustration of a line is a horizontal mark made on a piece of paper. A figure made by two rays that intersect at the same endpoint is referred to as an angle.
Given that in the diagram, the measure of angle 9 is 85°. 4 lines intersect to form 16 angles. The angles created, clockwise from the top left are 1, 2, 3, 4; 5, 6, 7, 8; 9, 10, 11, 12; 13, 14, 15, 16.
The measure of angle 9 is equal to the measure of angle 11. it means that angle 9 and angle 11 are equal to 85 degrees. The image is attached with the answer below. Shows the angle 9 and angle 11 are vertically opposite angles.

In "The Case for Shelter Animals," what does the author explain about the cost of becoming a pet owner?
Adoption costs more money than buying a pet.
Pet stores are more expensive than breeders.
It is more expensive to buy a pet than it is to adopt.
Cats are less expensive than dogs.
Question 2
Part B
Which evidence from the text best supports the answer to Part A?
"So those who buy from pet stores and breeders can expect to pay those fees on top of already-high purchase costs."
"The guide states that adopting a dog or a cat from a shelter usually costs between $50 and $500."
"Meanwhile, an animal from a pet store typically costs at least $1,000. Breeders are even more expensive."
"One reason that adopting pets from shelters is the logical choice is that shelter animals are less expensive than those bought from pet stores or breeders."
Answer:

Step-by-step explanation: i just took the test for k12
Statement 1 is incorrect.
Statement 2 is incorrect.
Statement 3 is correct.
Statement 4 is incorrect.
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.

FIND A AND B I WILL AWARD BRAINLIEST
Answer:
a = 7.4
b = 9.6
Step-by-step explanation:
set up a proportion to find 'b':
XN / NY = MN / NO
8/b = 13/(b+6)
cross-multiply:
13b = 8(b+6)
13b = 8b + 48
5b = 48
b = 9.6
set up a proportion to find 'a':
XN / XY = MN / MO
8/a = 13/12
cross-multiply:
13a = 96
a ≈ 7.4

PLEASE HELP!!!!!!!!!!
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
