1.) In a class of 45 students , 80% received A’s on a Math test . How many students received an A?2.) Mary spent 15 dollars. If this was 20% of her earnings, how much money did she earn ?
Answers
Answer 1
Answer:
Step-by-step explanation:
1) 45 times 0.8 (which is equivalent to 80 percent) is 36 students.
2) 15 divided by 0.2 is 75, so she earned 75 dollars
A triangle has an angle that measures 101.7°. The other two angles are in a ratio of 10:19. What are the measures of those two angles?
Answers
-- First ... You know that the angles of a triangle always add up to exactly 180° . So you know that the two missing angles add up to (180° - 101.7°) = 78.3° . That's the amount you need to split up in the ratio of 10:19 .
-- The smaller angle will get 10 shares of it. The larger angle will get 19 shares of it. Together, they'll add up to 29 shares of 78.3° .
-- OK. So what size is each share ? It's 78.3°/29 = exactly 2.7° .
-- The smaller angle gets 10 shares = (10 x 2.7°) = 27° .
The larger angle gets 19 shares = (19 x 2.7°) = 51.3° .
Check:
-- 27/51.3 = 10/19 <== good
-- (27° + 51.3° + 101.7°) = 180° <== good yay !

Please help me on these five questions.

so if talking about points on a graph then a. x is made negative or opposite of what it is basically, the x point would go x units from the zero line in the other way it is currently ie. reflected across the x axis
b. both x and y are positive, basically the figure would be reflected across the x axis then reflected across the y axis (or y axis then x, doesn't matter)
c. y times 2 y is 2 times as high (gets bigger)
d. 2/3 times x x is 2/3 as much as it was before (gets smaller)
e. 1/2 x and 1.5 y x get's half smaller and y gets 1.5 bigger (x gets smaller, y gets bigger)
A) When x is made negative, it gets reflected over the x-axis.
B) When x and y is made negative, it gets reflected over the x-axis and y-axis.
C) Every y-value from the equation would be multiplied by 2, thus changing the shape of the graph. The slope is divided by 2.
D) Every x-value from the equation would be multiplied by 2/3, thus changing the shape of the graph. The slope is divided by 2/3.
E) x-values are divided by 2 and y-values are multiplied by 1.5.
