Answer:
First triangle: 54.46 degrees
Step-by-step explanation:
For the first problem, solve for the third side, then the third angle, and then subtract from 180.
20^2 + 28^2 = c^2
400 + 784 = c^2
1184 = c^2
34.41 = third side
Find the third angle:
sin(90)/34.41 = sin(x)/20
20 * sin(90)/34.41 = sin(x)
35.54 is the third angle.
180 - 35.54 - 90 = 54.46. The angle with the question mark is 54.46. Do the other 2 problems the same way.

5. Shane has no more than $200 to spend on a
basketball game for next weekend. He spends
$44 on fees. If the tickets are sold at $78 each,
which inequality models t, the number of tickets
Shane is able to buy?
Answer:
[tex]t\leq2[/tex]
Step-by-step explanation:
200 - 44 = 156 dollars which Shane can use to buy tickets
156 >= 78t
t<=2
Therefore the maximum number of tickets he can buy is 2

Write the equation from the line whose slope and the point through which it passes are given. Express the equation in point-slope form. (8,-1) and slope m=-3
Answer:
y + 1 = 3(x - 8)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = 3 and (a, b ) = (8, - 1 ) , then
y - (- 1) = 3(x - 8) , that is
y + 1 = 3(x - 8)

How to convert statements into numerical expressions ?To convert statements into numerical expression break the statement into chunks write the terms with mathematical operations.Interpret twice, thrice, half of this etc logically.Practice a lot.
According to the given question I think of a number,Let the number be x.
I increase it by four and double (x+4)×2 = 2(x+4).
The result is 20 more than the number which is (x+20).
∴ 2(x+4) = (x+20)
2x + 8 = x + 20.
2x - x = 20 - 8.
x = 12.

The sum of half of a number and 49is 2 whole 1/4 of the number. find the number
Answer:
-93.5
Step-by-step explanation:
let the number be y
1/2 × y + 49 =2 1/4
y/2 +49 =9/4
y/2 =9/4-49
y/2 = 9-196/4
y/2 = -187/4
cross multiply
4y = -374
y = -93.5
Answer:

Let the number is x
Half of a number = (1/2) x2 whole 1/4 of the number = (2 1/4) x = (9/4) xThe sum:
(1/2) x + 49 = (9/4) x(9/4)x - (1/2)x = 49(9/4 - 1/2)x = 49(7/4)x = 49x = 49 : 7/4x = 49 * 4/7x = 7 * 4x = 28how to rewrite 3/4 with the denominator 12
A circle has diameter 18 inches, and a chord is 14 inches long. What is the distance in inches from the chord to the center of the circle, to the nearest hundredth?
Answer:
Let O be the center of a circle whose radius is r cm , in which AB= 14 cm long
cord is at a distanceof 24 cm from O. Draw a perpendicular OD on AB , thus ,
OD= 24 cm.
In right angled triangle. ODB
OB^2 = OD^2+ DB^2
r^2 =(24)^2+(AB/2)^2 = 576+(14/2)^2
r^2 = 576+ 49=625
r = √625. =25 cm. Answer.

Step-by-step explanation:
when x varies directly as 2y and x=6 when y=20 find y when x=9
Answer:
x=k×2y
substitute x for 6 and y for 20
6=2(20)×k
6=40k
Divide both sides by the coefficient of k
6/40=40k/40
3/20=k
To find y, when x=9
9=3/20×2y
9=6y/20
cross multiply
9×20=6y×1
180=6y
Divide both sides by the coefficient
y=30

There are 34 carpenters in a crew. On a certain day, 29 were present. What percent showed up for work? (round to the nearest tenth)
Answer:
About 85.29 percent
Step-by-step explanation:
Recall that a percentage can also be represented as a proportion under 1; for example, 30 percent is .30 as a proportion of 1. So here we have 29 carpenters out of 34 that showed up, a ratio of .8529 showed up to work, and .8529 balance translates to 85.29 percent.
So 85.29 percent of the carpenters showed up to work.

Make x the subject of the formula: y=x^{2} + 5
First, multiply both sides by (x - 5), so you end up with:
(x-5)y = x + 2
Which can be expanded to give you:
xy - 5y = x + 2
Now add 5y to both sides to obtain:
xy = x + 2 + 5y
Now subtract x from both sides:
xy - x = 2 + 5y
Factorise x out:
x(y - 1) = 2 + 5y
Divide both sides by (y - 1):
x = 2 + 5y/y - 1There you go, x is now the subject.
PLEASE HELP! No phony answers, thanks! Happy holidays, Merry Christmas!!
Step-by-step explanation:
(f+g)(x) means we just add the 2 functions, so we have
(x-3) + 2x² = 2x² + x - 3
(f-g)(x) means we subtract g(x) from f(x), so we have
(x-3) - (2x²) = -2x²+x-3
Assuming that the dot signifies a multiplication sign and not a composition sign, we have
(f*g)(x) = f(x) * g(x)
= (x-3) * 2x²
= 2x³ - 6x²
Plugging -2 in, we get
2(-2)³-6(-2)² = -16 -24 = -40
