In a recent survey, 78% people answered that there were at least four televisions in their household. If there were 300 people surveyed, how many people have at least four televisions in their home?
Answer:
234 people have a least 4 televisions in their home.
Step-by-step explanation:
In order to find 78% of a whole, you just have to multiply the whole by 0.78.
So we get....
300 x 0.78 = 234

Gertrude started an experiment with 15 gummy bears. After 6 days, there were 1,523 gummy bears. Write an exponential function that could be used to model the number of gummy bears after x days if the number of gummy bears changes at the same rate. Round to the 4th decimal place (ten thousandth)
y=a*b^x
a=
b=
9514 1404 393
Answer:
y = 15·2.1599^x
Step-by-step explanation:
We know that the number changed by the ratio 1523/15 = 101.5333... in 6 days, so the daily multiplier is the 6th root of this:
b = 101.5333...^(1/6) = 2.1599 . . . rounded to 4 dp
Of course, the coefficient 'a' in the equation is the initial number, 15.
Your exponential equation is ...
y = 15·2.1599^x
a = 15
b = 2.1599

A cylinder has a radius of 3 cm and a height of 25 cm. We fill the cylinder with water to a height of 15 cm. Then we add 5 golf balls to the water. Each golf ball has a radius of 2.2 cm. What will the new height of the water be?
Answer:
The new height of the water will:
[tex]H_{new}=22.89 cm[/tex]
Step-by-step explanation:
The submerged volume due to an object in a liquid, water in our case, is equal to the displaced volume of the water, it is the Archimedes principle.
The volume of a golf ball (sphere) will be
[tex]V_{ball}=\frac{4}{3}\pi r^{3}=\frac{4}{3}\pi 2.2^{3}[/tex]
[tex]V_{ball}=44.6 cm^{3}[/tex]
We have 5 golf balls, so the total volume will be:
[tex]V_{5-ball}=5*44.6 cm^{3}=223\: cm^{3}[/tex]
Using Archimedes' principle the extra volume of water will be 223 cm³
Now, we know that the cylinder has a radius of 3 cm, then the height related to 223 cm³ will be:
[tex]223=\pi r^{2}h[/tex]
[tex]223=\pi 3^{2}h[/tex]
[tex]h=7.89\: cm[/tex]
Therefore, the new height of the water will:
[tex]H_{new}=15+7.89=22.89 cm[/tex]

help me pls im stuck
Answer:
C.
Step-by-step explanation:
Hi there!
We know that [tex]x^0[/tex] is equal to 1 because any number raised to the zero is always going to be 1.
With that out of the way, we are left with [tex]x^-^3/1[/tex], which is equivalent to [tex]x^-^3[/tex]
Using negative exponent rules,
The expression is flipped and the -3 becomes a positive 3.
It will look like this
[tex]\frac{1}{x^3}[/tex]
Your answer is C.
I hope this helps!
Atiya rolls a 7.0 kg bowling ball down the
alley for the championship. One pin is still
standing, and Atiya hits it head-on with a
velocity of 9.0 m/s. The 2.0 kg pin moved
forward with a velocity of 14.0 m/s. What is
the new velocity of the bowling ball?
Answer:
5 m/s
Step-by-step explanation:
According to law of conservation of momentum :
m1u1 + m2u2 = m1v1 + m2v1
m1 = 7kg ; u1 = 9m/s ; m2 = 2kg ; u2 = 0 ; v2 = 14 m/s
m = masses ; u = initial velocities ; v = final velocities
m1u1 + m2u2 = m1v1 + m2v1
7*9 + 2*0 = 7*v + 2*14
63 + 0 = 7v1 + 28
63 = 7v1 + 28
63 - 28 = 7v1
35 = 7v1
v1 = 35 / 7
v1 = 5 m/s

In 1839, Georgia produced 326,000 bales of cotton . By 1860, the state produced 700,000 bales. What was the approximate percent of increase in the bales produced during that 21-year period?
Answer: 115% increase
Step-by-step explanation: To solve, we need to subtract the first value fro the second value. The formula is Percent Change = ((Second Value – First Value) ÷ First Value) x 100%
700,000-326,000=374,000. Then, divide the difference by the first value.
374,000÷326,000=1.1472392638≈1.15
1.15×100%=115%
Thus, the approximate percent of increase in the bales produced during that 21-year period is 115% increase
