Answer: question 6
4/7*8/10 =
first multiply the numeratores the the denominatos.
4*8=32 so this will be numerator.
7*10=70 this is denominator.
so answer is 32/70
same way question 7 is 28/40
question 8
11/2 *9/4 = 99/8= 12 3/8
question 9
convert to improper
9/5*7/3= 63/15 4 3/15
question 10
21/8*16/7= 336/56= 6/6
Step-by-step explanation:
This is the concept of trigonometry, the value of the measure of the supplementary angles can be obtained as follows;
supplementary angles sum up to 180 degrees, thus;
(2x+3)+(3x+2)=180
2x+3+3x+2=180
collecting like terms we get:
2x+3x+3+2=180
5x+5=180
5x=180-5
5x=175
thus;
x=175/5
x=35
Thus the value of the angles will be:
3x+2
=35*3+2
=107
the size of the other angle will be:
180-107
=73
Answer:
area = 8 in²
Step-by-step explanation:
area = 16/5 x 10/4 = 160/20 = 8 in²
Answer:
no
Step-by-step explanation:
<span>y=0.25x-7
y=1/4x-7
Slope of this line has a value of 1/4.
We know that k1*k2=-1 (if lines are perpendicular)
Then k2=-4
The equation of the second line is
y=-4x+b
If this line passes through the poin (-6;8), then 8=-4*(-6)+b
8=24+b
b=8-24
b=-16
The equation is y=-4x-16
