Answer:
140°
Step-by-step explanation:
The sum of angle of a triangle is equal to 180°.
Two of the angles measured 20°.
We need to find the measure of the third angle of Nora’s triangle. let the third angle is x. So,
20+20+x = 180
40+x = 180
x = 180-40
x = 140°
So, the third angle of the triangle is 140°.
Which relationships describe angles 1 and 2?
Select each correct answer.
vertical angles
complementary angles
adjacent angles
supplementary angles
Answer:
Complemtary angles
Step-by-step explanation:
they add up to 90* as visible by the right angle symbol

Answer:
n = 14
Step-by-step explanation:
Width of the given right angles triangle = (n + 6) cm
Since, height of this triangle is 10 cm less than the width.
Height = (n + 6) - 10
= (n - 4) cm
Area of a right angles triangle = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(n+6)(n-4)[/tex]
100 = [tex]\frac{1}{2}(n+6)(n -4)[/tex]
200 = n(n - 4) + 6(n -4)
200 = n² - 4n + 6n - 24
200 = n² + 2n - 24
n² + 2n - 224 = 0
n² + 16n - 14n - 224 = 0
n(n + 16) - 14(n + 16) = 0
(n + 16)(n - 14) = 0
n = -16, 14
Since n = -16 is an extraneous solution, so the answer is n = 14.

Find the equation of the line that contains the points whose coordinates are (−1, 0) ( − 1 , 0 ) and has slope 1/4
Answer:
[tex]\displaystyle y=\frac{1}{4}x+\frac{1}{4}[/tex]
Step-by-step explanation:
We want to find the equation of the line that passes through the point (-1, 0) and have the slope 1/4.
We can use the point-slope form given by:
[tex]\displaystyle y-y_1=m(x-x_1)[/tex]
We will substitute (-1, 0) for (x₁, y₁) and 1/4 for the slope m. Therefore:
[tex]\displaystyle y-(0)=\frac{1}{4}(x-(-1))[/tex]
Simplify:
[tex]\displaystyle y=\frac{1}{4}(x+1)[/tex]
Distribute. Thus, our equation is:
[tex]\displaystyle y=\frac{1}{4}x+\frac{1}{4}[/tex]
During each week of piano lessons, Justin learns to play 2 new pieces. In all, how many weeks of piano lessons will Justin need before he will be able to play a total of 46 pieces?
Answer:
23 weeks
Step-by-step explanation:
For 1 week he can learn 2 new pieces. He wants to pay 46 pieces. So we would make the following equation:
[tex]2x=46[/tex] where x is equal to the number of weeks
We can then solve for x by dividing 46 by 2.
[tex]\frac{46}{2} =23[/tex]
So in order for Justin to learn 46 pieces, it would take 23 weeks.
sebuah topi berbentuk kerucut dengan panjang diameter 18 cm dan tinggi topi tersebut 20cm berapakah volume nya
Answer:
The area of the cone is "1,695.6 cm³".
Step-by-step explanation:
The given values are:
Diameter of cone,
d = 18 cm
then,
Radius,
r = [tex]\frac{d}{2}[/tex]
= [tex]\frac{18}{2}[/tex]
= [tex]9 \ cm[/tex]
Height,
h = 20 cm
As we know,
⇒ Area of a cone = [tex]\frac{1}{3} \pi r^2 h[/tex]
On substituting the given values in the above formula, we get
⇒ = [tex]\frac{1}{3}\times 3.14\times (9)^2\times 20[/tex]
⇒ = [tex]\frac{1}{3}\times 3.14\times 81\times 20[/tex]
⇒ = [tex]3.14\times 27\times 20[/tex]
⇒ = [tex]1,695.6 \ cm^3[/tex]

A shopkeeper wants to sell pulses at a common rate.So he mixed three quality of pulses weighing 34.650 kg ,68.275 kg and 90.350 kg respectively . Find the total quality of pulse he has. What can you say about the shopkeeper?
Answer:
Q = 193.27 kg
Step-by-step explanation:
A shopkeeper mixed three quality of pulses weighing 34.650 kg ,68.275 kg and 90.350 kg respectively.
We need to find the total quality of pulse he has. It means, total quality of pulse he has is :
Q = 34.650 + 68.275 +90.350
= 193.27 kg
Hence, he has 193.27 kg pulse.

The sum of two numbers is 115. Their difference is 21. Find numbers. I need to show my answer
Answer:
The answer is 73 and 42
Step-by-step explanation:
1. Subtracting 21 from 115 which gives you 94, but that wouldn't be the answer because its asking for two numbers with a difference.
2. From you subtract 21 from 94 which is 73, next subract 73 from 115 which gives you 42.
3. 73 + 42 is 115

a worker at a mill is loading 5-lb bags of flour into boxes to deliver to a local warehouse.
Each box holds 12 bags of flour.
If the warehouse orders 3 tons of flour, how many boxes are needed to fulfill the order?
Answer:
x = 12 x 5 lb Pound of flour per box
x = 60 lb
2,000 lb = 1 T We need to multiply by the conversation rule.
y = 3 T x 2,000 lb FInd out how many pound are in 3 Tons.
y = 6,000 lb Pound of flour in the warehouse.
b = 6,000 lb / 60 lb Divded by the number of pound per box.
b = 100 lb boxes 100 boxes are needed.
The state volleyball association invited 64 teams to compete in a tournament.after each round , half The teams were eliminated.which equation represents the number of teams,t, that remained in the tournament after r rounds
A. t= 64(0.5)^r
B. t=64(r)^0.5
C. t=64(1.5$^r
D. t=64(-0.5)^r
Answer:
A
Step-by-step explanation:
You take the 64 teams, split it in half, and then the exponent is r
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
The equation that represents the number of teams t that remained in the tournament after r rounds is t = 64 x [tex](1/2)^{r}[/tex]
Option A is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example: 3x + 3 = 4 is an equation.
We have,
Number of teams = 64
The number of teams eliminated after each round = Half the team.
The equation represents the number of teams t that remained in the tournament after r rounds.
t = 64 x [tex](1/2)^{r}[/tex] ____(1)
Put r = 1, we must get 32 teams.
t = 64 x 1/2 = 32
Put r = 2 we must get 16 teams.
t = 64 x (1/2)² = 64 x 1/4 = 16
We see that (1) is the correct equation to represent the number of teams t that remained in the tournament after r rounds.
Thus,
The equation that represents the number of teams t that remained in the tournament after r rounds is t = 64 x [tex](1/2)^{r}[/tex]
Option A is the correct answer.
