Answer:
I think the answer is 10 sq cm
Step-by-step explanation:
Answer:
y = -4x - 11
Explanation:
y - y1 = m(x - x1)
<u>where </u><u>(x1, y1) are points</u><u> given and </u><u>"m" is slope</u>
<h3>
</h3>
Solve:
y -(-3) = -4(x-(-2))
y + 3 = -4(x+2)
y = -4x -8 -3
y = -4x - 11 ....equation in slope intercept form [ y = mx + b ]
Answer:
y=6,95x+35
y=6,95*5+35=69,75 for 5 hours
for 6 hours y=76,7
for 7 hours y=83.65
for 8 hours y=90,6
Step-by-step explanation:
Distance Keith ran = 26 miles
Time it took
= 3 hours 2 minutes = [(3 * 60) + 2] minutes = (180 + 2) minutes = 182 minutes
Hence,
Speed (Rate) =
miles per minute
Hence,
Time taken to complete 1 mile
=
= 7 minutes
Hence, the answer is B.
The problem can be solved by <span>proportion as following
</span>
<span>For every 15 columns of news stories in a newspaper, 4 columns of ads are required
</span>
If a newspaper contains 300 columns of news stories, x columns of ads are required
∴ 15 : 4 = 300 : x
∴
By using cross multiplication
∴ 15 x = 4 * 300
∴ 15 x = 1,200
∴ x = 1,200/15 = 80
So, the number of <span>
columns of ads must it have = 80
