ziro4ka [17]

Answer:

No. Reduce 10/8 by dividing by 2. 10/8= 5, 8/2= 4. 10/8= 5/4. Reduce 16/20 by dividing by 4. 16/4= 4 , 20/4= 5. 16/20= 4/5.

19 PTS!!!! PLZ HELP ASAP
Ira Lisetskai [31]

The number of muffin can yield is 18.

Step-by-step explanation:

Given:

The recipe needs  \frac{3}{4} cup chopped apple.

To find:

Umber of muffins when 1 \frac{1}{8} cup chopped apple is given.

Solution:

1\frac{1}{8} ÷  \frac{3}{4} = 1.5

1\frac{1}{8} cup apple is 1.5 times of \frac{3}{4} cup of apple

So, the number of muffins will be = 12 × 1.5

= 18

Thus 18 muffins can be yielded from a batch that contains 1 1/8 cups of chopped apple

PLS HELP ME WITH THIS !!
Mashutka [201]
Part 1:
180 = 5p+98 + 9p-2
180 = 14p + 96
84 = 14p
6 = p

part 2:
angle S will be the same as angle Q, so:
9p-2
9(6)-2

I need help on number 10 please!
hammer [34]

Answer: y = 4x/3 - 5/2

Step-by-step explanation:

The equation of a straight line can be represented in the slope intercept form as

y = mx + c

Where

c represents the y intercept

m = slope = (y2 - y1)/(x2 - x1)

The given line, L1 passes through A(6, - 7) and B(- 6, 2). The slope of line L1 is

m = (2 - - 7)/(- 6 - 6) = 9/ -12 = - 3/4

If two lines are perpendicular, it means that the slope of one line is the negative reciprocal of the slope of the other line.

Therefore, the slope of line L2 passing through the midpoint, M is 4/3

The formula determining the midpoint of a line is expressed as

[(x1 + x2)/2 , (y1 + y2)/2]

Midpoint, M = [(6 + -6)/2 , (- 7 + 2)/2]

= (0, - 5/2]

This means that the y intercept of line L2 is - 5/2

The equation of L2 becomes

y = 4x/3 - 5/2
