1.) Tyler runs 2/3 of a mile in 8 minutes. At this speed, how long will it take him to run one mile?
Answer:
12 minutes
Step-by-step explanation:
Since he ran 2/3 of a mile in 8 minutes, by dividing both sides by two we can see that he ran 1/3 in 4 minutes. 1/3 x 3 = 1 mile. 4 x 3 = 12 minutes
Answer:
1 mile in 12 minutes
Step-by-step explanation:
2/3 mile in 8 minutes
divide by 2
1/3 mile = 4 minutes
multiply by 3
1 mile in 12 minutes

Step-by-step explanation:
Given data
P= 5000
r= 8%
t= 1 year
The simple interest expression is given as
A= P(1+rt)
Required
The final amount A
substitute
A= 5000(1+0.08*1)

The figure is made up of 2 cones and a cylinder. The cones and
cylinder have a 4 cm diameter.
What is the exact volume of this figure?
отпCm3
0 12cm
0 207cm
0 367cm
Answer:
This question is unsolvable because:
1) Volume can't be measured in cm (think you mean cm^3)
2) Volume of the cylinder is calculated with its height and bottom area.
We can calculate its bottom area like this: (4/2)^2*pi
But since we do not know the cylinder nor the cones' height then we can't
calculate their volume.

Answer:
6 and 15
Step-by-step explanation:
x^2 + 9x = x^2 + 7x +12
2x = 12
x = 6
The dimension of the original rectangles are 6 inche and 15 inches.
What is a rectangle?A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
Original rectangle:
Length = x + 9
Width = x
Area = (x + 9)x
New rectangle:
Length = (x + 9) - 5 = x + 4
Width = x + 3
Area = (x + 4)(x + 3)
Now,
(x + 9)x = (x + 4)(x + 3)
x² + 9x = x² + 3x + 4x + 12
9x = 7x + 12
9x - 7x = 12
2x = 12
x = 6
Now,
The dimension of the original rectangle.
x + 9 = 6 + 9 = 15
x = 6
Thus,
The dimensions of the rectangles are 6 inches and 15. inches

Work out the total surface area of the prism.
Diagram NOT

8 cm
17 cm
20 cm
15 cm
Answer:
Total surface area of the prism = 920 cm²
Step-by-step explanation:
Given prism has 2 similar triangular surfaces and 3 rectangular surfaces of different dimensions.
Area of one triangular side = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
Area of 2 similar sides = Base × Height
= 8 × 15
= 120 cm²
Area of rectangular side with dimensions 17cm × 20cm
Area of the side = 17 × 20 = 340 cm²
Area of the second rectangular side with dimensions 8cm × 20cm
Area of the side = 8 × 20 = 160 cm²
Area of third rectangular side with dimensions 20cm × 15cm
Area of the side = 20 × 15 = 300 cm²
Total surface area of the given triangular prism = 120 + 340 + 160 + 300
= 920 cm²

Answer:
m(∠KJL) = 54°
Step-by-step explanation:
It's given that two sides of ΔJKL are equal in measure.
Therefore, angles opposite to the equal sides will be equal.
By triangle sum theorem in ΔJKL,
m∠KJL + m∠KLJ + m∠JKL = 180°
2(m∠KJL) + 72° = 180°
2(m∠KJL) = 180° - 72°
m∠KJL = [tex]\frac{108}{2}[/tex]
m(∠KJL) = 54°

A local council is concerned that there are too many students for staff to look after in schools. There are 18 staff and 225 students in school A. a Write the staff : student ratio in the form 1 : n.
you have to find a number they are both divisible by to get it to simplest form. 18:225.
divide both by 3. 6:75.
you can divide it by 3 again.
answer: 2:25
The ratio of two quantities can be obtained by writing them as a fraction. The ratio in the form of 1 : n is given as 225 / 18.
What is the application ratio and proportion?A ratio is the relation between two numbers as a / b. A proportion is the equality of two ratios as a / b = c / d.
Ratio and proportion can be applied to solve Mathematical problems dealing with unit values of the quantities.
Given that,
The number of staff in the school = 18
And, the number of students in the school = 225
Since, the ratio of two numbers a and b is given as a : b = a / b.
In the form of 1 : n it can be written as, a : b = 1 / (b / a).
Similarly, the ratio of staff and students n the form of 1 : n can be written as,
Staff : Students = 18 : 225
=> Staff : Students = 1 / (18 / 225)
=> Staff : Students = 225 / 18.
Hence, the ratio Staff : Students can be written in the form 1 : n as 225 / 18.

The graph of y=f(x) is the solid black graph below. Which function represents the dotted graph?
Not that hard, will give brainlist if correct
Answer: y = f(x - 4) - 1, lower left corner
=============================================================
Explanation:
Let's focus on only the left-most points of each curve
For the black semicircle, the left-most point is located at (-7,0). The corresponding point on the red semicircle is at (-3,-1)
To go from (-7,0) to (-3,-1), we will do two things
Shift 4 units to the rightShift 1 unit downThis can be done in any order. The action of "shift 4 units to the right" is effectively the same as shifting the xy axis 4 units to the left while keeping the curves fixed in place. This gives the illusion of movement. When we shift 4 the xy axis 4 units to the left, we're replacing each x input with x-4 as the new input.
In short, we go from f(x) to f(x-4). This is why we have this opposite motion going on.
The up and down motion is fairly straight forward. To shift 1 unit down, we subtract off 1. This is to subtract 1 from the y coordinate.
Overall, we go from y = f(x) to y = f(x - 4) - 1
Applying this transformation will move (-7,0) to (-3,-1) as described above. It will also move every other point on the black curve to their new corresponding location on the red curve.
