Answer:
Part A: 272 teenagers surveyed like hard rock.
Part B: 200 is the total number of teenagers that Damian surveyed.
Part C: Polly surveyed 850 teenagers to find out their favorite type of music. She found that 132% of the teenagers surveyed like hard rock.
Step-by-step explanation:
Part A: % = 1/100, 32% = 32/100, so 32% of 850 is
32/100 x 850 = 272.
Part B: if Total is T, then 75% of T is = 150, i.e,
75/100 x T = 150, making T subject of relation, then T, Total = 200.
Answer:
Option d is the correct answer
Step-by-step explanation:
The slope-intercept form of an equation for a line passing through given points can be represented as
y = mx + c
Where
Slope, m = (change in value of y on the vertical axis) / (change in value of x on the horizontal axis)
c = y-intercept
We want to find the slope-intercept form of an equation for the line that passes through (–1, 2) and is parallel to y = 2x – 3
For two lines to be parallel to each other, the slopes must be equal.
For y = 2x – 3
Slope,m = 2 (comparing with the slope intercept form stated above).
This means that the slope of the line
that passes through (–1, 2) is also 2
To find the y-intercept, c of this equation,
2 = 2 × - 1 + c
2 = -2 + c
c = 2+2 = 4
The equation is
y = 2x + 4
Answer:
22
Step-by-step explanation:
220 x 15 ÷ 150 = 22
or each gallon gives him 10 miles.
for 220 miles he needs 22 gallons
Answer:
Y-intercept is (0,8)
Step-by-step explanation:
The line of an equation is y=mx+b. M in this case is 1 and "b" is the y intercept. since in the place of b is positive 8 the y-intercept is 8
