Answer:
The angle of CAD is 100°.
Step-by-step explanation:
Given that total angles in a triangle is 180° so you will have to find the angle of CAB :
∠CAB + ∠ACB + ∠ABC = 180°
∠CAB + 80° + 20° = 180°
∠CAB + 100° = 180°
∠CAB = 180° - 100°
∠CAB = 80°
Next, you have to subtract it from 180° because straight line have a degree of 180°
∠CAD = 180° - 80°
∠CAD = 100°

Joseph ran LaTeX: 2\frac{3}{4}2 3 4 miles in LaTeX: \frac{2}{5}2 5 of an hour. How fast did Lin run in 1 hour? (try to leave your answer in a fraction) Nathaniel ran LaTeX: 8\frac{2}{3}8 2 3 miles in LaTeX: \frac{4}{3}4 3 of an hour. How fast did Nathaniel run in 1 hour? (try to leave your answer in a fraction) Who ran the fastest, Nathaniel or Joseph?
Answers
Answer:
Nathaniel ran fastest
Step-by-step explanation:
For Joseph
Joseph ran 2 3/4 miles 2 /5 of an hour.
Speed = Distance/Time
Speed = 2 3/4 miles ÷ 2/5 hour
= 11/4 ÷ 2/5
= 11/4 × 5/2
= 55/8 miles/hour or 6.875 miles/hour
How fast did he run in 1 hour? (try to leave your answer in a fraction)
Hence, this is calculated as:
2/5 hour = 55/8 miles per hour
1 hour = x
Cross Multiply
x = 55/8 ÷ 2/5
x = 55/8 × 5/2
x = 275/16 miles per hour
x = 17 3/16 miles per hour
Nathaniel ran LaTeX: 8 2/3 miles in 4 /3 of an hour. How fast did Nathaniel run in 1 hour? (try to leave your answer in a fraction)
Speed = Distance/Time
Speed = 8 2/3 miles ÷ 4/3hour
= 26/3 ÷ 4/3
= 26/3 × 3/4
= 26/4 miles/hour
How fast did he run in 1 hour? (try to leave your answer in a fraction)
Hence, this is calculated as:
4/3 hour = 26/4miles per hour
1 hour = x
Cross Multiply
x = 26/4 ÷ 4/3
x = 26/4 × 3/4
x = 78/16 miles per hour
x = 4 14/16 miles per hour
= 4 7/8 miles per hour
Who ran the fastest, Nathaniel or Joseph?
Hence, from the calculation above, Nathaniel ran fastest

Answers
Answer:
15) C (3, -4)
16) B (-1, 1)
Step-by-step explanation:
8x + 6y = 0
8x + 2y = 16
8x + 2y = 16
8x = 16 - 2y
x = 2 - 1/4y
8x + 6y = 0
8(2 - 1/4y) + 6y = 0
16 - 2y + 6y = 0
16 + 4y = 0
4y = -16
y = -4
8x + 2y = 16
8x + 2(-4) = 16
8x - 8 = 16
8x = 24
x = 3

-20x - 3y = 17
10x - 4y = -14
-20x - 3y = 17
-20x = 17 + 3y
x = -17/20 - 3/20y
10x - 4y = -14
10(-17/20 - 3/20y) - 4y = -14
-8.5 - 1.5y - 4y = -14
-8.5 - 5.5y = -14
-5.5y = -5.5
y = 1
-20x - 3y = 17
-20x - 3(1) = 17
-20x - 3 = 17
-20x = 20
x = -1

Step-by-step explanation:
Quadrilateral ABCD is translated down and left to form quadrilateral OLMN.
Quadrilateral A B C D is translated down and to the left to form quadrilateral O L M N.
If AB = 6 units, BC = 5 units, CD = 8 units, and AD = 10 units, what is LO?
5 units
6 units
8 units
10 units
Answers
Answer:
LO = 6 units ⇒ B
Step-by-step explanation:
Translation does not change the size or the shape of the figure
∵ Quadrilateral ABCD is translated down and left to form
quadrilateral OLMN
∴ The image of side AB is side OL
∴ The image of side BC is side LM
∴ The image of side CD is side MN
∴ The image of side AD is side ON
∵ AB = 6 units
∵ Translation does not change the size of the figure
∴ The image of AB = 6 units
∵ The image of AB is OL
∴ The length of OL = 6 units
∵ OL = LO
∴ LO = 6 units
The length of LO of the newly translated quadrilateral is; Option B: LO = 6 units.
Translation of objects in mathematics simply means to move an object from one point to another without a change of length or figure.
Now we are told that Quadrilateral ABCD is translated down and left to form quadrilateral OLMN.
Thus means Quadrilateral OLMN is still same size and length as ABCD and as such the sides will correspond in order.
Thus, it means that;
AB = OL
BC = LM
CD = MN
AD = ON
We are given;AB = 6 units, BC = 5 units, CD = 8 units, and AD = 10 units
Thus, since AB = OL, we can say that;
LO = 6 units.

Answers
The students who audition will be in the play is 40%
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that Students are auditioning for a school play
Only 18 of the 45 students auditioning will get a part in the play.
We need to find the percent of the students who audition will be in the play.
45x=18
Divide both sides bby 45
x=18/45
x=0.4
Now multiply with 100 as it is hundredth part
0.4×100=40%
Hence, the students who audition will be in the play is 40%
