70°
xo
115°
A 45°
B. 550
C. 57.59
D. 22.50
Answer:
A. 45°
Step-by-step explanation:
By exterior angle theorem:
x + 70° = 115°
x = 115° - 70°
x = 45°
Answer:
x= 45°
Step-by-step explanation:
triangles degrees all together are always 180°
x≠180°
a straight line is also 180°
180°-115°= 65°
70°+65°= 135°
180°-135°= 45°

Suppose that when a car goes over a bump, the impact hat must be absorbed by the suspension is directly proportional to the square of the car's speed. Of a car going 12 mph receives 4000 units of impact, ow much impact will a car received at 30 mph
Answer:
10000 units of impact
Step-by-step explanation:
From the above question:
12 mph = 4000 units of impact
30 mph = x units of impact
Cross Multiply
12 mph × x units = 30 mph × 4000 units
x units = 30 mph × 4000 units/12 mph
x units = 10000 units of impact.
Therefore, 30 mph receives 10000 units of impact

The sales tax in one state is 3%. Write a function rule for finding the total cost of an item with selling price x. Then find the total cost of a CD player with a selling price of $150.
f(x) = x – 3; $148.97
f(x) = 3 + x; $151.03
f(x) = 0.03x; $4.50
f(x) = 1.03x; $154.50
Answer: brainly.... D. f(x) = 1.03x; $154.50
ok so the cd player cost
$150 the sales taxs is 7% so you do
7% of 150= $10.50
so you add
$150+$10.50= $160.50
so the total cost is $160.50

a rectangle has a perimeter of 158 cm and the given area of 804 cm^2 Its length is 7 more than five times its width. Write and solve a system of equations to find the dimensions of the rectangle.
2(3x – 1) = 6x – 2 number of solutions
Answer: All real numbers are solutions.
Step-by-step explanation:
Let's solve your equation step-by-step.
2(3x−1)=6x−2
Step 1: Simplify both sides of the equation.
2(3x−1)=6x−2
(2)(3x)+(2)(−1)=6x+−2(Distribute)
6x+−2=6x+−2
6x−2=6x−2
Step 2: Subtract 6x from both sides.
6x−2−6x=6x−2−6x
−2=−2
Step 3: Add 2 to both sides.
−2+2=−2+2
0=0

The combined height of one fir tree and one pine tree is 21 meters. The height of 4 fir trees stacked on top of each other is 24 meters taller than one pine tree.
How tall are the types of trees that Logan genetically engineered?
Answer:
The pine is 12 m tall and the fir is 12 m tall
Step-by-step explanation:
System of Equations
Let's call:
x = height of a pine tree
y = height of a fir tree
The combined height of one fir tree and one pine tree is 21 meters. This leads to the equation:
x + y = 21 [1]
The height of 4 fir trees is 24 meters taller than one pine tree:
4y = x + 24 [2]
From [1]:
x = 21 - y [3]
Substituting in [2]:
4y = 21 - y + 24
Adding y:
5y = 45
Dividing by 5:
y = 9
Substituting in [3]:
x = 21 - 9 = 12
The pine is 12 m tall and the fir is 12 m tall
