Answers
Answer:
48 tons of steel per year
Step-by-step explanation:
you can make it a ratio problem but you can also divide it
144 tons : 3 years
? : 1 year
take 144/3 and you get
48 tons
so
48 tons : 1 year
Answer:
Unit rate= 36
Step-by-step explanation:
Divide 144 by 4 and you get 36. So, the steel company made 36 tons of steel in 1 year and made 144 tons of steel in 4 years
A rectangle has a width of 12. 5 m and a length of 105 m. What is the effect on the perimeter when the dimensions are multiplied by 2? The perimeter is increased by a factor of 2. The perimeter is increased by a factor of 21. The perimeter is increased by a factor of 25. The perimeter is increased by a factor of 92.
Answers
The perimeter of the rectangle is got increased by a factor of 2. The correct option is A.
What is a rectangle?It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In rectangle opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at mid-point.
Given
A rectangle has a width of 12.5 m and a length of 105 m.
We know the perimeter of the rectangle is given by
Perimeter = 2 (Lenght + Width)
Let x be the length and y be the width. Then
Perimeter = 2 (x + y)
If the dimensions are multiplied by 2. Then the effect on the perimeter will be
Perimeter = 2 (2x + 2y)
Perimeter = 2 [2 (x + y)]
The perimeter is increased by a factor of 2.
Thus, option A is correct.

which statement best explain best explains whether the table represents a linear or non linear function (100 POINTS) HURRYYYY PLSSS
Answers
Answer:
It is a linear function because there is a constant rate of change in both the input and output values
Step-by-step explanation:
To determine if the function is linear, calculate the differences between the y values.
If the differences are constant, or the same value, the equation is linear and has a constant slope. If the differences are not the same, the equation is not linear.
difference between y values (output)
7 - 4 = 3
3 - 1 = 3
1 - -2 = 3
⇒ the function is linear
difference between x values (input)
-2 - -5 = 3
-5 - -8 = 3
-8 - -11 = 3
⇒ the function is linear as there is a constant rate of change in both the input and output values
What is the equation of the line that passes through the point (−8,−7) and has a slope of 1?
Answers
Answer:
y = x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = 1 , then
y = x + c ← is the partial equation
To find c substitute (- 8, - 7 ) into the partial equation
- 7 = - 8 + c ⇒ c = - 7 + 8 = 1
y = x + 1 ← equation of line

Question 9
In △QRS , ∠R is a right angle and the measure of ∠S is 22° .
(image below)
Which equation can be used to calculate the measure of ∠Q ?
A
x+22=180
B
x+22=90
C
22−x=180
D
22−x=90
Answers
Answer:
i think the answer is b
because,
if x+22=90
x=90-22=68
we know that the sum of the three angles of a triangle is 180
so, that means
90+22+68 should be 180
and it is 180, so the answer must be b
I need help find the value of x?
Answers
Add the two angles and then subtract from 180* to find the missing angle
So,
145* + 15* = 160*
180* - 160* = 20*
Answer: x = 20*
