Answer:
Approximately 20525 seconds
Step-by-step explanation:
Distance between San Francisco and Los Angeles is not given.
Therefore, by using I-5 S, distance between these cities = 381.6
≈ 382 miles
Formula for the average speed is,
Average speed = [tex]\frac{\text{Distance traveled}}{\text{Time taken}}[/tex]
Time taken to reach San Francisco from Los Angeles = [tex]\frac{\text{Distance traveled}}{\text{Average speed}}[/tex]
= [tex]\frac{382}{67}[/tex]
= 5.702 hours
≈ 5 hours 42 minutes
≈ 342.1 minutes
≈ 20525 seconds

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

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.
Answer:
y = 2x + 2

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.

Step-by-step explanation:
If the value of 3/4 divided by x Is the whole number which number is the value of x?
A whole number is a number that has no fractional representation.
Let's test all the options for the value of x.
When dividing a fraction by another fraction, the divisor will be in its reciprocal form.
1. 3/4 × 2/3
= 6/12 = 1/2
1/2 isn't a whole number.
2. 3/4 × 2/1
= 6/4 = 3/2
3/2 isn't a whole number.
3. 3/4 × 6/1
= 18/4 = 9/2
9/2 isn't a whole number.
4. 3/4 × 8/1
= 24/4 = 6
6 is a whole number.
Hence the answer is 1/8.

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 = 210000Write 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]
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.
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
