Let the normal speed = x mph
The way to his grandmothers they drove 2x miles
Return trip was 2.25(x-5)
Set those equal and solve for x:
2x = 2.25(x-5)
Simplify:
2x = 2.25x -11.25
Subtract 2.25x from both sides:
-0.25x = -11.25
Divide both sides by-0.25:
X = 45
The usual speed is 45 mph.
So now 2 hours at 45 mph = 90 miles to his grandmothers house
Answer:
90 miles

why do planets orbit
Answer:
Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.

a street sign is 104 inches tall. How tall is it in feet and inches.
Answer:
8 ft 8 in
Step-by-step explanation:
104/12 = 8.666...
This shows that there are 8 total feet because there are 12 inches in a foot
Then, multiply 8*12 to get 96 in order to get the remainder of the inches left that do not make up one whole foot.
Then subtract 96 from 104 (104-96) to get the remainder which is 8 inches.

HELP MY HOMEWORK SO HARDDDD
Answer:
6.7
Step-by-step explanation:
Theres a formula to figure this out. If you know two sides of a right angle triangle you can find the third.
Use the formula a²=b²+c², where a is the side opposite the right angle and b and c are the other sides.
a²=b²+c²
7²=2²+c²
49=4+c²
49-4=c²
c=√45 or 6.7082039325
Find the probability of rolling divisors of 24
Answer:
5/6 is the probability
Step-by-step explanation:
Factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24 and rolling a 6-sided die you can get 1, 2, 3, 4, 5, 6 so 5 is the only thing you can roll that isn't a factor of 24 so

September December March $10,000 $10,000 $9,000 $9,000 $8,000 Goal $7,000 $10,000 $9,000 $8,000 Goal $8,000 Goal $7,000 $7,000 $6,000 $5,000 $6,000 $5,000 $4,000 $3,000 $2,000 $1,000 $6,000 $5,000 $4,000 $4,000 $3,000 $3,000 $2,000 $1,000 $2,000 $1,000 60 Grade Grade 6 Grade (a) On the first day of school, Bethany's family donated $60 to the field trip fundraiser. What percent of their total goal did Bethany's family donate? F 0.75% G 75% H 2.5% J 0.25%
Answer:
0.75%
Step-by-step explanation:
Total amount to generate at fundraiser = $8000
Amount donated by Bethany family = $60
The percentage of Bethany's donation towards the fundraiser is :
Let percentage = x
x% of 8000 = 60
x/100 * 8000 = 60
0.01x * 8000 = 60
80x = 60
Divide both sides by des by 80
80x / 80 = 60 / 80
x = 0.75
In the triangle below,
x= [ ? ]°. Round to the nearest
tenth.
Answer:
X = 38.7°
Step-by-step explanation:
Reference angle = x
Opposite side length = 8 cm
Adjacent side length = 10 cm
Applying trigonometric ratio formula, we have:
[tex] tan(x) = \frac{8}{10} [/tex]
[tex] x = tan^{-1}(\frac{8}{10}) [/tex]
[tex] x = 38.7 [/tex]
x = 38.7° (to the nearest tenth)

At a bagel shop the first 6 bagels purchased cost 55 cents apiece, and additional bagels cost c cents apiece. If a customer paid $5.70 for 12 bagels, what is the value of c?
Answer:
C = 0.475
Step-by-step explanation:
you divide 5.70 by 12 and get that one bagel costs 0.475 cents. hope this helps!
c=40 is the answer
6x55=330 cents
$570-570 cents (570-330)÷(12-)
=240÷6 (division)
=40 cents
Thus, c=40

Answer:
16
Step-by-step explanation:
The distance is given by
d = sqrt( (x2-x1) ^2 + ( y2-y1) ^2)
Since the x values are the same
d = sqrt( ( y2-y1) ^2)
d = sqrt( (( -6 - 10)^2))
d = sqrt((-16) ^2)
d = 16
We can also just find the number of squares between the points since the x value is the same.

h=5+17t-16t^2
Find all values of t for which the ball's height is 9 feet.
Round your answer(s) to the nearest hundredth.
Answer:
-16t²+17t+7=11
==>16t²-17t+4=0
Δ=17²-4*4*16=33
