Rectangle C has length 30 and width 15.
Rectangle B is a scaled copy of Rectangle A. What is the scale factor?
Select all equivalent answers.
1.25
4/5
5/4
20.8
11/4
Answers
Answer:
1.25
5/4
1 1/4
Step-by-step explanation:
The dimensions of rectangle A are L=12 and W=8. The dimensions of rectangle B are L=15 and W=10.
We are told rectangle B is a copy of rectangle A, thus we must find the scale factor by dividing both dimensions:
15/12=5/4
10/8 =5/4
Dividing 5/4 we get 1.25.
Converting 5/4 to mixed fraction: 5/4= 1 1/4
There are three valid selections:
1.25
5/4
1 1/4
Arielle has a collection of grasshoppers and crickets. She has 561 insects in all. The number of grasshoppers is twice the number of crickets. Find the number of
each type of insect that she has.
crickets and
grasshoppers
Answers
Answer:
Arielle has 374 grasshoppers and 187 crickets
Step-by-step explanation:
Let's set:
x = number of grasshoppers
y = number of crickets
Arielle has a collection of 561 insects, thus:
x + y = 561 [1]
The number of grasshoppers is twice the number of crickets, thus:
x = 2y [2]
Substituting [2] in [1]:
2y + y = 561
Simplifying:
3y = 561
Dividing by 3:
y = 561/3
y = 187
From [2]:
x = 2*187 = 374
x = 374
Arielle has 374 grasshoppers and 187 crickets

write the equation of the polynomials in factored form that has the following zeros: -8, -4, 5, 5, 2
Answers
Explanation:
When finding a zero, you set the equation equal to 0 then solve.
For example, x+8=0
You would isolate x by subtracting both sides by 8 and get x=-8. This mean that the root or zero is -8. When there are two zeros that are the same, you just square the equation.

Answer:
A. y = 8x
Step-by-step explanation:
y is the product, and x is one of the variables that will multiply another number to equal y. So x times a variable equals y, then y divide by x would equal that variable. And in the questions it gave us if y = 48 and x = 6. So we'll use that: 48/6 = 8, the variable is 8. 8 times 6 equals 48 so:

What’s the measure of angle X?
Answers
Answer:
x = 84°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
129° is an exterior angle of the triangle, thus
x + 45° = 129° ( subtract 45° from both sides )
x = 84°

Abes apples orchard plants both green apple trees and red apple trees this planting will include 21 red apple trees and 18 green apple trees what is the ratio of green apple trees and red apple trees
Answers
Answer:
The ratio of green apples to red apples is .
Step-by-step explanation:
Given,
Number of red apples = 21
Number of green apples = 18
We have to find out the ratio of green apples to red apples.
Solution,
For finding the ratio we have to divide the number of green apples to the number of red apples.
So, we can frame the above sentence as;
Ratio = number of green apples/number of red apples
Now substituting the values, we get;
Ratio= 18/21 = 6/7
Hence The ratio of green apples to red apples is . 6/7
Find an equation of the line that passes through (3,10) and is parallel to the line x-3y=1
Answers
Answer:
x - 3y = -27
Step-by-step explanation:
Two parallel lines have equations of the same form; only the constants differ.
Thus, if the given line is x - 3y = 1, the desired new line has equation of the form x - 3y = C, where we must find the value of C.
Substituting 3 for x and 10 for y in x - 3y = C, we get 3 - 3(10) = C, or
3 - 30 = C. Thus, C = -27 and the desired new line is x - 3y = -27.

The perimeter of the isosceles right triangle is P = 6 + 3√2 feet
What Is an Isosceles Triangle?A triangle with two sides of equal length is an isosceles triangle. The isosceles triangle has three acute angles, meaning that the angles are less than 90°. The sum of three angles of an isosceles triangle is always 180°.
In an isosceles triangle, the two equal sides are called legs, and the remaining side is called the base. The angle opposite the base is called the vertex angle
The three types of Isosceles Triangles are :
Isosceles acute triangle
Isosceles right triangle
Isosceles obtuse triangle
Given data ,
Let the isosceles triangle be represented as ΔABC
In an isosceles right triangle, the two legs are congruent, so if one leg has a length of 3 ft, then the other leg also has a length of 3 ft. Let's call the length of the hypotenuse h.
Using the Pythagorean theorem, we can find the length of the hypotenuse:
h² = 3² + 3²
h² = 18
Taking square roots on both sides , we get
h = 3√2 feet
The perimeter of the triangle is the sum of the lengths of its sides:
Perimeter = 3 + 3 + 3√2 = 6 + 6 + 3√2 feet
Hence , the perimeter is 6 + 3√2 feet
