A person takes up 18 inches of space on a stadium bleacher. If one row of bleachers is 100 feet long and
there are 20 rows of bleachers, how many people can fit into the stands?
The number of people who can fit into the stands in the stadium is 1,333 people
Number of people in the stadiumSpace taken by each person = 18 inches
Length of a row of bleachers = 100 feet
Rows of bleachers = 20
Conversion of feet to inches1 feet = 12 inches
100 feet = 1200 inches
Number of people per row = 1200 inches ÷ 18 inches= 66.67 people
Number of people that fits the stand = Number of people per row × Rows of bleachers= 66.67 × 20
= 1,333.4
Approximately,
1,333 people can fit into the stands in the stadium

the largest metric prefix that is ordinarily used is tera, while the smallest prefix is pico. How much larger is a teramtere
Answer:
A terameter is 10²⁴ times larger than a picometer.
Step-by-step explanation:
Here is the complete question:
The largest metric prefix that is ordinarily used is tera, while the smallest prefix is pico. how much larger is a terameter than a picometer.
Step-by-step explanation:
1 tera = 10¹² and
1 pico = 10⁻¹²
To determine how much larger a terameter is than a picometer, we will divide the value of 1 terameter by the value of 1 picometer.
1 terameter = 10¹² meters and
1 picometer = 10⁻¹² meters
1 terameter / 1 picometer = 10¹² / 10⁻¹²
= 10¹²⁻⁽⁻¹²⁾
= 10¹²⁺¹²
= 10²⁴
Hence, a terameter is 10²⁴ times larger than a picometer.

How would you describe this pattern's rule? 65, 62, 59, 56, 53,50
The rule of the pattern follows that each successive number is 3 lesser than the preceeding Value.
The first term = 65
Second term = 65 - 3 = 62
Third term = 62 - 3 = 59
Fourth term = 59 - 3 = 56
Fifth term = 56 - 3 = 53
Sixth term = 53 - 3 = 50
Therefore, each successive number is reduced by 3.

A bus travels at a constant speed of 48 km/h. How long will it take to travel 600 km?
Answer:
It will take 12 and 30 hours
Step-by-step explanation:
To solve this, you need to divide by distance needed to travel by the speed
600/48 is equal to 12.5 hours.
.5 hours is equal to 30 mins because 60mins times .5 is 30 minutes, therefore the final answer is 12.5 hours

Answer:
I am not fully sure, but I believe y=3x+2 as for on the x axis it is on -1 and going up 2 times and one to the right it will give you the y axis part which is 2 and you nade 3 moves so it is 3x for the moves and 2 for y.

Step-by-step explanation:
[tex]6z-7=2z-2\qquad|\text{add 7 to both sides}\\\\6z-7+7=2z-2+7\\\\6z=2z+5\qquad|\text{subtract}\ 2z\ \text{from both sides}\\\\6z-2z=2z-2z+5\\\\4z=5\qquad|\text{divide both sides by 4}\\\\\dfrac{4z}{4}=\dfrac{5}{4}\\\\\boxed{z=\dfrac{5}{4}}[/tex]
Answer: z = 5/4
Step-by-step explanation: First simplify the equation by subtracting 2z from both sides and adding 7 to both sides to get 4z = 5.
Step by step below
6z -7 = 2z -2
-2z -2z
4z -7 = -2
+7 +7
4z = 5
Now divide both sides by 4 to get z = 5/4
4z/4 = 5/4
z = 5/4

Students at three elementary schools collected a total of 29,294 cans of food to donate to a local food bank. Students at Johnson Elementary collected 9,987 cans of food, while students at Lincoln Elementary School collected 12,462 cans of food. How many cans of food did students at Richardson Elementary School collect
Answer:
6,845 cans
Step-by-step explanation:
Total of 29,294 cans of food to donate to a local food bank
Students at Johnson Elementary collected 9,987 cans of food
Students at Lincoln Elementary School collected 12,462 cans of food.
Total number of food can collected =
Food cans at Johnson Elementary + Food cans at Lincoln Elementary +
Food cans at Richardson Elementary
The Food cans collected at Richardson Elementary = Total food cans - (Food cans at Johnson Elementary + Food cans at Lincoln Elementary )
= 29,294 cans - (9,987 + 12,462) cans
= 29,294 cans - 22,449 cans
= 6,845 cans
Therefore, the cans of food that the students at Richardson Elementary School collected is 6,845 cans

Brody is going to invest in an account paying an interest rate of 3.7% compounded monthly. How much would Brody need to invest, to the nearest hundred dollars, for the value of the account to reach $34,000 in 13 years?
Answer:
21000
this is the answer
The value of the account is to reach $34,000 in 13 years with a rate of 3.7 compounded monthly is $ 21,000.
What is compound interest?Compound interest is the interest on a loan or deposit calculated based on the initial principal and the accumulated interest from the previous period.
Brody is going to invest in an account paying an interest rate of 3.7% compounded monthly.
The rate of interest yearly will be
[tex]\rm Yearly \ rate = \dfrac{3.7}{12}\\\\Yearly \ rate = 0.308 \%[/tex]
The value of the account is to reach $34,000 in 13 years.
Amount (A) = $ 34,000
Time (t) = 13 years
Rate (r) = 0.308 %
Then the principal amount will be
[tex]\begin{aligned} A &= P (1 + \dfrac{r}{100})^{12*t}\\\\34000 &= P (1 + \dfrac{0.308}{100}) ^{13 * 12}\\\\34000 &= P (1.00308)^{156}\\\\P &= 21,044 \approx 21,000 \end{aligned}[/tex]
The principal amount is $21,000.

Answer:
[tex]\mathbf{ x^2 + (y-8)^2 +(z)^2 = 32}[/tex]
Step-by-step explanation:
Given that:
The center of the sphere = (0,8,0)
[tex]The \ equation \ of \ the \ tangent \ plane \ is:[/tex]
= x - y = 0
x = y
However, the radius of the sphere is equal to the perpendicular distance of the plane from the center.
As such, the radius [tex]r = \Big | \dfrac{ax_1 +by_1+cz_1}{\sqrt{a^2 + b^2 +c^2}} \Big |[/tex]
[tex]r = \Big | \dfrac{1*0 +(-1)*8+0*0}{\sqrt{1^2 + (-1)^2 +0^2}} \Big |[/tex]
[tex]r = \Big | \dfrac{-8}{\sqrt{2}} \Big |[/tex]
[tex]r = \dfrac{8}{\sqrt{2}}[/tex]
[tex]r = \dfrac{4 \times 2}{\sqrt{2}}[/tex]
[tex]r = 4\sqrt{2}[/tex] units
Thus, the equation of the sphere [tex]r^2 = (x -x_1)^2 +(y-y_1)^2 +(z -z_1)^2[/tex]
[tex]\mathbf{\implies x^2 + (y-8)^2 +(z)^2 = 32}[/tex]
