1. For every 4 boys, there are 3 girls.
2a. 14-p
2b. (d+f)/8
2c. 2x+5
2d. c/6
3a. 2a+2b
3b. 21d+12e
3c. 8a+24b
4. Speed = distance/time
5a. 101 boys and 121 girls
5b. 8 won + 4 lost = 12 games in total
6a. 65
6b. 657
6c. 98
7a. 49.99
7b. 110.92
Hope these answers are correct! Please mark me as brainliest!
3x - 2y = 7
-2y = -3x + 7
y = 3/2x - 7/2....slope of this line is 3/2. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So the slope we need is -2/3 (see how I flipped the slope and changed the sign)
y = mx + b
slope(m) = -2/3
(-3,-2).....x = -3 and y = -2
now we sub and find b, the y int
-2 = -2/3(-3) = b
-2 = 2 + b
-2 - 2 = b
-4 = b
so ur perpendicular equation is : y = -2/3x - 4 <==
It will be a negative.
for an example: -20 for x would mqke 2x + 1 into -39 and 8x + 5 into -155. that's 116 apart, so maybe -2(8) + 5 = -11
-2(2) + 1 = -3
but that's only 8 apart, so it'd be higher.
-4(2) + 1 = -7
-4(8) + 5 = -27
BOOM
Tadaaaa,
You probably thought positive, but sometimes it's negative, you know what I mean?
Answer: SOLUTION -
Let’s convert first the unit dimension of the garden from inches-feet to yards.
HEIGHT: 4 in * (1 ft / 12 in) = 1/3 ft * (1 yard/3 ft) = 1/9 yard
WIDTH: 28 ft * (1 yard/3 ft) = 28/3 yards
LENGTH: 32 ft * (1 yard/3 ft) = 32/3 yards
Then, let’s get the total soil capacity or volume of the garden:
(32/3) * (28/3) * (1/9) = 896/81 = 11.06 cubic yards
Since we can’t buy 0.06 cubic yard of soil, we need to round off 11.06 to the next number of cubic yards that is exactly divisible by 1/4.
It will give us then with 11 & 1/4 cubic yards.
