One angle of a triangle measures 20°the other two angles are in a ratio of 3:5. What are the measures of those two angles?
Answer:
180-20 = 160 = sum of the other two angles
3/(3+5) = 3/8 x 160 = 60 degrees
5/(3+5) = 5/8 x 160 = 100 degrees
or in radians the other two angles are pi/3 and 5pi/9

Find f(–2) for the function f(x) = 3x2 – 2x 7. −13 −1 1 23
Answer:
16
Step-by-step explanation:
f ( x ) = 3x² - 2x
To find : f ( - 2 )
f ( - 2 ) = f ( x )
Here,
x = - 2
f ( - 2 ) = 3 ( - 2 )² - 2 ( - 2 )
= 3 ( 4 ) - 2*( - 2 )
= 3*4 + 4
= 12 + 4
f ( - 2 ) = 16

Answer:
76 feet^3
Step-by-step explanation:
Well, since s is showed three times on the large box, we can say they are all the same lengths. So, if one side is 4 feet long, then all side length, are 4. So, 4*4*4. This gets us 64.
So the large box's volume is 64, and the small one, is 12. The total volume is them added. 64+12. This gets us 76.
The answer is 76 feet^3
9. Blake is putting carpet in a large
room. He has enough carpet to cover
50 square meters of floor. If Blake
first decides on the length of the
rectangle he's going to cover, the
equation below will tell him what the
width of the rectangle can be.
The equation that will tell him what the width of the rectangle can be is w = 50m² / length.
What equation represents the width of the rectangle?
A rectangle is a 2-dimensional quadrilateral with four equal right angles. A rectangle has two diagonals that are equal in length and bisect each other.
Area of a rectangle = length x width
Width = area / length
width = 50m² / length.

Isaac bought snacks for his team's practice. He bought a bag of chips for $2.94 and a 8-pack of juice bottles. The total cost before tax was $16.62. How much was each bottle of juice?
Answer:
$1.71
Step-by-step explanation:
Just took the test.
The cost of each juice bottle is $1.71.
Let, the cost of each juice bottle as "x".
Given:
Cost of chips = $2.94
Total cost before tax = $16.62
Isaac bought an 8-pack of juice bottles, so the total cost of the juice bottles is 8x.
The total cost of chips and juice bottles should be equal to the total cost before tax:
Cost of chips + Cost of juice bottles = Total cost before tax
$2.94 + 8x = $16.62
Now, solve for "x" the equation:
8x = $16.62 - $2.94
8x = $13.68
Divide both sides by 8:
x = $13.68 / 8
x = $1.71.
So, the cost of each juice bottle is $1.71.

of the money and he will spend the same amount each day. How many dollars
will Sonia spend each day of the vacation?
Answer:
$15
Step-by-step explanation:
Sonia will take $57, and his grandparents will give another $78. 57 + 78 = 135. Sonia will have 135 dollars, but it is a 9 day vacation, so 135/9 = 15
Sonia will spend 15 dollars a day.

Misty needs 216 square inches of metal
to make a yield sign.
If the height of the sign is 18 inches,
how long is the top edge of the sign?
24 inches
12 inches
198 inches
22 inches
Answer:
24
Step-by-step explanation:
Area = 216
The area of triangle = 1/2 b * h
Since height = 18 --> 1/2 b * 18
so,
216 = 1/2 b * 18
Divide both sides by 18
12 = 1/2 b
Divide both sides by 1/2, (which is the same as multiplying both sides by 2)
24 = b
Answer:
24 inches
Step-by-step explanation:
Given:
[tex]\bullet \ \ \text{Height of sign: 18 inches} \\ \bullet \ \text{Area of Yield sign: 216 inches}^{2}[/tex]
The yield sign shown here is a triangle. Therefore, the question is asking to find the base of the triangle. Keep in mind that the area of a circle is 1/2 multiplied by the base multiplied by the height.
[tex]\implies \text{Area of yield sign} = \dfrac{1}{2} \times \text{Base} \times \text{Height}[/tex]
Substitute the height and the area in the equation and simplify.
[tex]\implies \text{216 inches}^{2} = \dfrac{1}{2} \times \text{Base} \times 18[/tex]
[tex]\implies \text{216 inches}^{2} =\text{Base} \times 9[/tex]
Divide both sides by 9.
[tex]\implies \dfrac{\text{216}}{9} =\dfrac{\text{Base} \times 9}{9}[/tex]
[tex]\implies24 \ \text{inches} =\text{Base}[/tex]

If f(x) = mx² - 6x - 3 and f'(1) = 12. find the value of constant in (a) 9 (b) 3 (c)-3 (d) -4
Answer:
a) 186
b) 6
c) 42
Step-by-step explanation:
[tex]f(x) = m {x}^{2} - 6x - 3[/tex]
f'(1) = 12
f'(x) = 2mx - 6
12 = 2(1)m - 6
12 - 6 = 2m
[tex] \frac{2m}{2} = \frac{6}{2} [/tex]
[tex]m = 3[/tex]
[tex]f(x) = 2 {x}^{2} - 6x - 3[/tex]
a)
f(9) = 3( 9)^2 - 6(9) - 3
f(9) = 186
b)
f( 3) = 3( 3)^2 - 6( 3) - 3
f(3) = 6
c)
f( - 3) = 3( - 3)^2 - 6( - 3) - 3
f(-3) = 42

I think know the answer but I’m unsure of how to do it
Answer:
36
Step-by-step explanation:
you have to isolate your variable. To do this, you add 24 to each side. On the left side its 12+24 and on the right, its 24+(-24) which then equals zero. In simple terms, x=12+24
Answer:
x = 36
Step-by-step explanation:
Add 24 to 12 because 24 is minus, so when it is moved to the other side of the equation it is plus.
