Answer/Step-by-step explanation:
1.
✔️a = 180 - 110 (consecutive angles are supplementary)
a = 70°
✔️b = a (corresponding angles are congruent)
b = 70°
✔️c = 110° (alternate interior angles are congruent)
2.
✔️a = 180 - 120 (linear pair)
a = 60°
✔️b = a (corresponding angles are congruent)
b = 60°
✔️c = a (alternate interior angles are congruent)
c = 60°
3.
✔️a = 55° (corresponding angles are congruent)
✔️b = 55° (Vertical angles are congruent)
✔️c = 180 - 55 = 125° (linear pair)
4.
✔️a = 115° (corresponding angles are congruent)
✔️b = 180 - a (linear pair)
b = 180 - 115
b = 65°
✔️c = b (vertical angles are congruent)
c = 65°
5.
✔️a = 180 - 25 = 155° (supplementary angles)
✔️b = 25° (corresponding angles)
✔️c = 25° (vertical angles)
6.
✔️a = 180 - 10 = 170° (linear pair)
✔️b = a (corresponding angles are congruent)
b = 170°
✔️c = 10° (corresponding angles are congruent)
What would the answer be?
Answer:
11.35%
Step-by-step explanation:
Add all of the numbers together to get the total amount of people who visited.
Add all the numbers in the teen section to find how many teens visited.
If you put teens over whole it will give you the fraction 86/758
If you divide 86 by 758 you will get 0.11345646438 .
Move the decimal two places to the right and round to get the percent 11.35.
find the difference between (14-3x) and (-9x+7)
Answer:
Step-by-step explanation:
The difference between 14 - 3x and - 9x + 7 is
= 14 - 3x - ( - 9x + 7)
= 14 - 3x + 9x - 7
= 6x + 7

what is the surface area
Answer:
The surface area of the rectangular prism is 748 ft2.
Step-by-step explanation:
formula for surface area: A=2(wl+hl+hw)
A=2(wl+hl+hw)=2(5x16+14x16+14x5)=748
Answer:
748 ft²
Step-by-step explanation:
For the surface area, you need to add up the area of all sides, six in this example, but it can be simplified into three by multiplying some of them by two as its presumed a rectangle
x1 = 5*14*2 = 140
x2 = 16*14*2 = 448
x3 =16*5*2 = 160
You find the sum of these; 140 + 160 + 448 = 300 + 448 = 748

One week, seventy-two percent of the animals that came to a veterinary hospital were dogs. If there were 230 animals total, how many were dogs?
Answer:
166 dogs were at the veterinary hospital
Step-by-step explanation:
Here, we want to know the number of dogs that were at the veterinary hospital
From the question, 72% of these animals are dogs
72% of a total of 230
Mathematically, the number of dogs are as follows;
dogs = 72% of 230
dogs = 72/100 * 230 = 165.6
since we cannot have a fractional dog, we round off to the nearest whole number which is 166 dogs
The Ski Club sells 180 keychains. A third of the keychains sold are blue and 1/6 of the remaining keychains are white. The rest of the keychains are red. How many keychains are red?
Answer:
Step-by-step explanation:
blue = ⅓×180 = 60
180-60 = 120 are not blue.
white = ⅙×120 = 20
120-20 = 100 are red

What is the slope of the line that contains these points?
x

11
y
-3
-2
-1
0
Answer:
Step-by-step explanation:
The slope of the line y = (x/4) - 23/4 is 1/4.
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
Given:
The points,
x → y
-4 → -3
1 → -2
6 → -1
11 → 0
From the table, we interpreted 2 points (-4, -3) and (11, 0)
If a line passes through two points (x₁ ,y₁) and (x₂, y₂),
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
m = (0+3) / (11+4)
m = 1/5
So, the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) (x - x₁)
y - y₁ =m (x - x₁)
y +3 = (1/4) (x -11)
y = (x / 4) - 11/4 -3
y = (x/4) - 23/4
Therefore, the slope of the line is m = 1/5.

Answer:
10
Step-by-step explanation:
See the angles on the black line. They are supplementary.
7x+90°+20°=180°
7x+110°=180°
7x=180°-110°
7x=70°
x=70°/7
