HELP, DUE IN 15 MINUTES! In triangle ABC, the measure of ∠B is 90°, BC=16, and AC=20. Triangle DEF is similar to triangle ABC, where vertices D, E, and F correspond to vertices A, B, and C, respectively, and each side of triangle DEF is [tex]\frac{1}{3}[/tex]
the length of the corresponding side of triangle ABC. What is the value of sinF?
Answer:
Triangle ABC is a right triangle with its right angle at B. Therefore, AC is the hypotenuse of right triangle ABC, and AB and BC are the legs of right triangle ABC. According to the Pythagorean theorem
Step-by-step explanation: AB=202−162=400−256=144=12
Since triangle DEF is similar to triangle ABC, with vertex F corresponding to vertex C, the measure of angle∠F equals the measure of angle∠C. Therefore, sinF=sinC. From the side lengths of triangle ABC,
sinF=oppositesidehypotenuse=ABAC=1220=35
Therefore, sinF=35.
The final answer is 35 or 0.6.

Answer:
Answer 19:- x = 5
Answer 20:- x = 11
Step-by-step explanation:
Answer 19:-
2x + 10 = 20
2x = 10
x = 5
Answer 20:-
80 + 20x = 300
20x = 220
x = 11
Answer:
19. x = 5
This is because Elise need $20, so we are going to figure out x
First, subtract 10 by both sides
2x = 10
Then, divide both sides by two to isolate the variable
x = 5
5 cars is the minimum
================================================================
20. He can stay for 11 nights.
First we subtract 80 by both sides
20x = 220
Then we isolate the variable by dividing both sides by 20
x = 11
Elena is buying cups and plates for her party. Cups are sold in packs of 8 and plates are sold in packs of 6. She wants to have the same number of plates and cups.
Find the multiples of plates and cups. She will not have more than 80 guests at her party!
What is the LCM? (The number of people at the party!)
How many packs of cups and packs of plates will she need to buy for that number?
_____ packs of plates and
_____ packs of cups so
she has _____ of each.
Answer the blank and questions
Answer:
For 80 people, Elena would need
14 packs of plates and 10 packs of cups
She would have at least 80 of each.
I am not completely sure of this, sorry if wrong.
Step-by-step explanation:
80 people
8 cups per pack
6 plates per pack
8, 16, 24, 32, 40, 48, 56, 64, 72, 80
6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84
LCM (least common multiple) = 24

Using x=7, how can we solve for the angle "9x+61"?
Answer:
124
Step-by-step explanation:
9x + 61
9 (7) + 61
63 + 61
124
Answer:
24
Step-by-step explanation:
Ok so your equation is 9x+61 and since you said that the X=7 you would replace the X with a 7 in the equation so now you have 9(7)61 and if the two numbers where together that means you would multiply 9x7 which is 63 and once you have that then you would just simply add 63+61 and you would get your total amount of 124.
I hope I explain this well and clear for other equations that may be similar to this.

To find the quotient of two fractions, you first need to rewrite the division problem as an equivalent multiplication problem. Find this quotient using multiplication
What is the reciprocal of the divisor?
Rewrite the division problem as an equivalent multiplication problem using the reciprocal of the divisor.
Answer:
10/18 simplifeid= 5/9
Step-by-step explanation:
Change the division sign to a multiplication sign
flip 6/5 to 5/6 (which is the reciprocal)
then multiply across the top and bottom
2x5=10
3x6=18
10/18 divided by 2 is 5/9

Jada has a monthly budget for her cell phone bill. Last month she spent 120% of her budget, and the bill was $60. What is Jada’s monthly budget?
Answer: The answer is $50.
Reasoning: If 120% equals to $60, then you can use the rule of three to calculate the value for 100%. Cross multiply, the answer will be $50.

Answer:
9. x=-6, y=0
10. x=-9, y=-10
11. x=3, y=-1
Step-by-step explanation:
[tex]2x-9y=-12\\3x+18y=-18[/tex]
Multiply the first equation by 2.
[tex]4x-18y=-24\\3x+18y=-18[/tex]
Add the equations.
[tex]7x=-42[/tex]
[tex]x=-6[/tex]
We figured out x now we have to figure out y. To figure out y plug in x into any equation.
[tex]2(-6)-9y=-12[/tex]
[tex]-12-9y=-12[/tex]
[tex]-9y=0[/tex]
[tex]y=0[/tex]
Your answer is x = -6 and y = 0 for number nine.
[tex]6x+3y=24\\2x+3y=-12[/tex]
Change the signs of the second equation becuase 3y and 3y are both positive. We need one of them to be negative.
[tex]6x+3y=24\\-2x-3y=12[/tex]
Add them.
[tex]4x = 36[/tex]
[tex]x=9[/tex]
Now we have to figure out y.
[tex]2(9)+3y=-12[/tex]
[tex]18+3y=-12[/tex]
[tex]3y=-30[/tex]
[tex]y=-10[/tex]
x=-9 and y=-10 is your answer to number ten.
[tex]10x+5y=25\\-7x-3y=-18[/tex]
[tex]30x+15y=75\\-35x-15y=-90[/tex]
[tex]-5x=-15[/tex]
[tex]x=3[/tex]
[tex]-7(3)-3y=-18[/tex]
[tex]-21-3y=-18[/tex]
[tex]-3y=3[/tex]
[tex]y=-1[/tex]
x=3 and y=-1 is the answer to number eleven. I hope this helps! Let me know if I got anything wrong.
