if it takes jessica 28.9 seconds to walk to the bus stop and there are 260 days she takes the bus to school a year. Then how many minutes a year does she spend walking to the buss stop? Round to the nearest minute
Answer:
Step-by-step explanation:
If there are 260 days and she takes 28.9 seconds to get to the bus stop, then that means 260 * 28.9 = 7514 seconds to get to the Stop. 7514 / 60 = number of minutes which is 125 rounded
Solve x − 2y = 3 for x.
Answer:
[tex]x=2y+3[/tex]
Step-by-step explanation:
So we have the equation:
[tex]x-2y=3[/tex]
And we want to solve for x. In other words, we want to isolate the x-variable.
So, add 2y to both sides of the equation.
[tex](x-2y)+2y=(3)+2y[/tex]
On the left, the 2y cancel. Simplify the right:
[tex]x=2y+3[/tex]
And we're done!
Answer:
x = 3 + 2y
Step-by-step explanation:
This is the answer because:
1) First, you have to isolate x, in order to isolate x you have to bring x to the end of the equation.
2) Then, you have to add 2y to both sides of the equation.
Another way you can think of this is:
1) If you add 3 + 2y you would figure out the answer because if you want to find x for a subtraction equation, you can add the answer to the equation with the number.
For example, x - 20 = 10, now to figure this equation out, you can either isolate the x, or you can add the answer in the equation with the remaining number in the equation.
Hope this helps!
Question 5 of 10
Solve 2x + 4 > 16.
O A. x<10
O B. x> 10
O C. x>6
O D. x< 6
Answer:
C
Step-by-step explanation:
2x +4 > 16
If you plug in 6 where the x is, and multiply 2 by 6, you get 12. Add 4 to 12 to get 16. If x is 6 it equals 16, so if x > 6 the answer will be more than 16.

That passes through (-4,0) and is parallel to y= -2x+1
Answer:
y = -2x - 8
Step-by-step explanation:
Parallel lines always have the same slope. Here, it is -2.
So, our equation so far looks like this:
y = -2x + b, where b is the y-intercept
We need to find b. We know our line passes through (-4, 0), so let's plug -4 in for x and 0 in for y:
y = -2x + b
0 = -2 * (-4) + b
0 = 8 + b
b = -8
Since b = -8, our equation is thus y = -2x - 8.

Two angles are supplementary if the sum of their measures is 180.
For the function g(x) = x – 2x^2, find g (–3) + 13
Answer:
g( - 3) + 13 = - 2Step-by-step explanation:
g(x) = x - 2x²
To find g( - 3) + 13 substitute the value of x that's - 3 into g(x) and add 13 to it
We have
g( - 3) + 13 = - 3 - 2(-3)² + 13
= -- 3 - 2(9) + 13
= 3 - 18 + 13
We have the final answer as
g( - 3) + 13 = - 2Hope this helps you

Answer:
Since r is the distance from the origin to (x,y), it is the magnitude r=√x2+y2. Alternatively, from the equation (1), one can calculate directly that x2+y2=r2cos2θ+r2sin2θ=r2(cos2θ+sin2θ)=r2.

The afternoon temperature in Biscoff Bay was – 2°F. By midnight, a warm front moved in and the temperature rose to 11°F. What was the change in temperature from afternoon to midnight? To solve the problem, Ross subtracted 11–( – 2) and came up with an answer of 13°F. Is Ross correct? Why or why not?
Answer:
Ross is correct. He is right because if you do 11- (-2) the double negatives turn into a positive and the answer is 13.
The answer is "Yes", Ross is right, and the temperature change will be 13 °F.

4. Find the width of a rectangle if the perimeter is
14.00 inches and the length is 3.6 inches.
Answer:
The width of the rectangle is 3.4 inches
Step-by-step explanation:
3.6 inches = length LxW=Area
W= width
Perimeter= 2x(Length)+2x(Width) 2x3.6=7.2
7.2+2(W)=14.00 subtract 7.2 on both sides 14.00-7.2=6.8
2(Width)=6.8 divide both sides by 2 6.8/2=3.4
So width of rectangle is 3.4
Courtney and Malik are buying a rug to fit in a
50-square-foot space, Which rug should they
purchase? Explain.
$99 Rug Sale!
7 ft x 7 ft
8 ft diameter
6 ft x 8ft
Rug Emporium has your floors covered.
Answer:
I think its 7x7 because it equals to 49 and its the closest to 50 and the rug would fit better than 6x 8 1/2=51 becuase 49 is smaller and would fit better.
Step-by-step explanation:
The area of a 2D form is the amount of space within its perimeter. The correct option is B, 8ft diameter.
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
Since Courtney and Malik want the rug to fit in an area of 50-square-foot space. Therefore, we need to first calculate the area of the given rugs, and then choose the one that can completely cover the area.
7 ft x 7 ft → Area = 7 ft x 7 ft = 49 ft²8 ft diameter → Area = (π/4)×Diameter² = (π/4)×(8ft²) = 50.2654 ft² 6 ft x 8ft → Area = 6 ft x 8ft = 48 ft²Now, as it can be seen that the only rug that can completely cover the 50-square-foot area is the one that has a diameter of 8 ft.
Hence, the correct option is B, 8ft diameter.

Angle XYZ = 2X ° and angle PQR = (8X -20)° if angle XYZ and angle PQR or supplementary find the measure of each angle angle XYZ = ?
Answer:
angle XYZ = 40°
Step-by-step explanation:
given,
angle XYZ = 2x°
angle PQR = (8x-20)°
now,
2x+8x-20° = 180°{being supplementary angle}
or, 10x - 20° = 180°
or, 10x = 180°+20°
or, x = 200°/10
or, x = 20°
again,
angle XYZ = 2x°
= 2× 20°
= 40°

Hey there! I'm happy to help!
The domain is all of the x-values of a function.
So, we take all of the x-values from our points.
0,-1,2,1
To express the domain, you order the numbers from least to greatest and put it in brackets, so the domain is {-1,0,1,2}.

[tex]5t-9=-3t+7[/tex]
Let's start by adding 3t to both sides of the equation.
[tex]5t-9+3t=-3t+7+3t\\8t-9=7[/tex]
Now let's add 9 to both sides of the equation.
[tex]8t-9+9=7+9\\8t=16[/tex]
Now let's divide both sides by 8.
