Triangle abc is a right triangle, and measure of A = 42. Find the value of n
find the value of x
Answer:
x = 5
Step-by-step explanation:
(10/3)/5 = (x+1)/9
(10/3)9 = 5(x+1)
90/3 = 5x + 5
30 = 5x + 5
25 = 5x
x = 5
the ratio of boys to girls is 15:11 .if boys are 435 find the number of girls
Answer:
[tex]Girls = 319[/tex]
Step-by-step explanation:
Given
[tex]Boys: Girls = 15:11[/tex]
Required
Find Girls, when Boys = 435
Substitute 435 for Boys
[tex]435: Girls = 15:11[/tex]
Express as fraction
[tex]\frac{Girls}{435} = \frac{11}{15}[/tex]
Multiply through by 435
[tex]435 * \frac{Girls}{435} = \frac{11}{15}* 435[/tex]
[tex]Girls = \frac{11}{15}* 435[/tex]
[tex]Girls = \frac{11* 435}{15}[/tex]
[tex]Girls = \frac{4785}{15}[/tex]
[tex]Girls = 319[/tex]
Plz help ASAP 20 Points Determine the equation of circle A.
(x - 1)2 + (y + 2)2 = 9
(x + 1)2 + (y-2)2 = 9
(x-1)2 + (y + 2)2 = 3
(x + 1)2 + (y-2) = 3
Answer:
the answer is c
Step-by-step explanation:
your equation is to solve the circle so A could not be the answer B/c it can't be 9.the answer is c or d. But d can't give you 3 if you solve it. so the answer is C

Can someone help me with this plz??
Answer:
f(x) = -4x-1
f(7) = -(4)(7)-1
f(7) = -29
g(x) = 4x^2 - x
g(-4) = 4(-4)^2 - (-4)
g(-4) = 4(16) + 4
g(-4) = 64 + 4
g(-4) = 68

It takes Tony 15 hours to rake the front lawn while his brother, Jose, can rake the lawn in 12 hours. How long will it take them to take the lawn working together?
Answer:
they can finish
[tex] \frac{1}{15} + \frac{1}{12} \\ [/tex]
in one hour
[tex] \frac{4 + 5}{60} \\ \frac{9}{60} [/tex]
in 6 hours they can finish
[tex] \frac{9}{60} \times 6 \\ \frac{54}{60} [/tex]
so the left work
[tex] \frac{60 - 54}{60} [/tex]
[tex] \frac{6}{60} [/tex]
they can perform
[tex] \frac{3}{60} work in60 \: minutes \div 3[/tex]
so the can perform
[tex] \frac{6}{60} work \: in \: 20minutes \times 2[/tex]
the take 6 hours and 40 minutes
Sean earns $ 6.70 per hour working after school. He needs at least $155(greater than or equal to 155) for a stereo system. Write an inequality that describes how many hours he must to reach his goal.)
Answer:
6.70h <= 155
Step-by-step explanation:
1. Define a variable.
Let h = number of hours
2. Write the inequality.
We know that he earns $6.70 an hour. We also know that he needs at least $155, which means he needs greater than or equal to 155. Therefore, 6.70h <= 155.
How do I solve this question
Answer:
6) x = 6.75
7) x = 27.29
Step-by-step explanation:
cross multiply
6)_______________________
9/16 = x/12
16x = 108
divide by 16
x = 6.75
7)_______________________
7/11 = 18/x + 1
7x + 7 = 198
-7 -7
7x = 191
divide by 7
x = 27.29

Answer:
[tex]\Huge\boxed{-8}[/tex]
Step-by-step explanation:
Hello there!
When given two ordered pairs we can use the slope formula to solve for the slope
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where m = slope
All we have to do is plug in the y and x values into the formula and calculate the slope
[tex]m=\frac{1-9}{7-6} \\1-9=-8\\7-6=1\\\frac{-8}{1} =-8\\m=-8[/tex]
So we can conclude that the slope of the line that passes through the points (6,9) and (7,1) is -8

B. $679
C. $421
D. $877
Step 1: multiply each original amount by .08 (because that's the percent amount)
For example: 415 x 0.08 = 33.2
Step 2: Add that product to the original amount.
For example: 415 + 33.2 = 448.2
Step 3: Don't forget to round to nearest dollar.
For example: 448.2 --> 448

10. Solve for z: 2 + 8 - z = -24
Answer:
The answer is z = 34.
Step-by-step explanation:
1) Simplify 2 + 8 - z to 10 - z.
[tex]10 - z = - 24[/tex]
2) Subtract 10 from both sides.
[tex] - z = - 24 - 10[/tex]
3) Simplify - 24 - 10 to -34.
[tex] - z = - 34[/tex]
4) Multiply both sides by -1.
[tex]z = 34[/tex]
Therefor, the answer is z = 34.
