Answer:
10 %
Step-by-step explanation:
15 mn = 1/4 h
We have :

Then the percentage that 15 mn represents of 5/2 h is :
0.1 × 100 = 10 %
Answer:
m∠y=72°
Step-by-step explanation:
<u><em>The question is</em></u>
Find the measure of angle y
step 1
Find the measure of angle x
see the attached figure to better understand the problem
we know that
m∠x=67° -----> by corresponding angles
step 2
Find the measure of angle y
we know that
(m∠x+m∠y)+42°=180° -----> because form a straight line
substitute the measure of angle x
67°+m∠y+42°=180
m∠y+108°=180
m∠y=180°-108°
m∠y=72°
Answer:
6 items are being purchased
Step-by-step explanation:
Given that variable p represents the number of items being purchased, and the variable t represents the time required to ring up the customer, If it takes 44 seconds to ring up a customer then the number of items being purchased may be computed by substituting the value of t into the given equation
t = 4p + 20.
Using t = 44
44 = 4p + 20
collect like terms or subtract 20 from both sides
44 - 20 = 4p
24 = 4p
Divide both sides by 4
24/4 = p
p = 6
Answer:
Rational
Step-by-step explanation:
It can be expressed as the ratio of two integers.
i.e. 0.01011011101111 = 1 011 011 101 111 / 100 000 000 000 000
Substitute z with 3.
3(4)^3
Cube 4 with 3
3(64)
Multiply 3 and 64
