Step-by-step explanation:
always try to bring fractions you need to compare to the same denominator (bottom number).
we have 9/10 of the pizza left.
then 4/5 if the pizza are eaten.
how to compare 9/10 with 4/5 ?
by bringing 4/5 also to a fraction of 10ths.
what do I need to multiply 5 with to get 10 ?
right, 2.
since we don't want to change the overall value of the original fraction, we need to multiply both levels (numerator and denominator) by that same factor :
4/5 × 2/2 = 8/10
aha !
that we can compare with 9/10.
so, when Lucas ate 4/5 (= 8/10) of the pizza, when there was originally 9/10 left, then we have 1/10 of the pizza left.
In this parallelogram, angle A and B add up to 180 (they are supplementary). Set up an equation like this and solve:
3x + 4 + 143 = 180
3x + 147 = 180
3x = 33
x = 11
The measure of x is 11°.
Answer:
D. 40 miles
Step-by-step explanation:
If Mark rides 20 miles for every hour and he rides for 2 hours, then just multiply his time with his rate.
20 x 2 = 40
15x<130+20, 15x<150 divided both sides by 15 ,the answer is 10
Answer:
93.03 in
Step-by-step explanation:
Height of square pyramid: √slant height² - (1/2 base side length)²
SH = √93.7² - 11.2² = 93.03
