Answer:
39 inches.
858 inches²
Step-by-step explanation:
Length:- (if length = x)
2 ( 11 + x ) = 100
22 + 2x = 100
2x = 100 - 22
2x = 78
x = 78 ÷ 2
x = 39 inches
Area:-
Area = l × b
= 39 × 22
= 858 inches²

The range of f(x) = [xl is y 2 0. If a < 0 for g(x) = a[x], what is the range of function g?
A ysa
B. y < 0
C. y20
D. ys 0
Answer:5
Step-by-step explanation:
The range of the function g(x) = a[x], where a < 0, is y ≤ 0.
What is the greatest integer function?The function f(x) = [x], where [x] represents the greatest integer less than or equal to x, has a range of y ≤ 0. This means that the output of the function f(x) can be any number less than or equal to zero, including negative integers, zero, and non-negative fractions.
Consider the function g(x) = a[x], where a is a negative constant. When we multiply the input x by a the output of the function is also multiplied by a. Since a is negative, the sign of the output is flipped. Moreover, the output is an integer, as [x] is an integer for all x.
Here, the range of the function g(x) = a[x] is y ≤ 0.
This means that the output of the function g(x) can be any negative integer, zero, or any non-positive fraction, as these are the numbers that are less than or equal to zero.
Thus, the range of the function g(x) = a[x], where a < 0, is y ≤ 0.

Biologist tagged 700 rabbits in Bryer Lake National Park. At a later date, they found 6 tagged rabbits in a sample of 1800. Estimate
the total number of rabbits in Bryer Lake National Park.
Answer:
210000 rabbitsStep-by-step explanation:
Ratio of tagged to non-tagged is:
6 : 1800 = 1 : 300This is 300 non-tagged per 1 tagged
Since there are 700 tagged rabbits, the estimated number is:
700*300 = 210000the 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.

Find the perimeter of this semi-circle with diameter,
d
= 32cm.
Give your answer as an expression in terms of
π
.
Answer:
let the
radius = diameter/2= 32/2= 16cm
now
perimeter of semi circle = 1/2×22/7×r
= 1/2×22/7×16
= 25.14cm
hence perimeter of semi circle is 25 .14cm
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.

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

Answer:
[tex]\huge\boxed{\sqrt{25^{3}}}[/tex]

When we have a number to a fraction power, we need to note that
It's the same as taking the denominator root of the base to the numerator powerBasically, for example, [tex]5^{\frac{1}{2}}[/tex] is the same as [tex]\sqrt{5}[/tex] since the numerator is 1 ([tex]5^1 = 5[/tex]) and the denominator is 2 ([tex]\sqrt{5}[/tex]).

Which linear equation is modeled by the graph?
A)-2x-3y=15
B)2x-3y=-15
C)2x+3y=-15
D)2x-3y=15
The answer is option A. If you observe the graph carefully...you can observe that the slope is positive and the y-intercept is -5. But it doesn't match with any in the option. That means you have to simplify every equation. For that move the X values to the right hand side then move the coefficient of y to the right hand side...that should give you the solution. This will take time and one shouldn't spend time in mcq. To save your time....just play around with signs. You can get the solution directly. we can observe that the slope is positive and if we move the positive X values then we will be getting negative slope...which ain't meeting the condition....thus we have to move the negative X to the right hand side to have positive slope...thus option a is correct.
Find the surface area of the square pyramid
Answer:
341 m²Step-by-step explanation:
surface area of a square base pyramid = base area + 4 ( triangular sides area)
where:
base = 11 m
side height length = 10 m
Surface area = 11² + 2(11)10
= 121 + 220
= 341 m²

What is the rule for the function that is graphed?
• y = 2x
• y = 3x + 2
• y = 2x + 2
• y = x – 2
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.

Write an equation of a sphere with center ( 0 , 8 , 0 ) (0,8,0) , and with the sphere tangent to the plane with equation x
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]
