Which of the following ratios are equivalent to 60%?
Check all that apply.
O A. 4:6
OB. 10:20
O C. 12:36
O D. 3:5
O E. 15:25

Answers

Answer 1

Answer:

D. 3:5 and E. 15:25

Step-by-step explanation:

If it is 60%, it means that the ratio is 6:10 (60/100).

Because both 6 and 10 are divisible by 2, we can then simplify the ratio to 3:5.

Therefore it is D. 3:5

We can then multiply both sides by 5 which will give us 15:25, so E is also correct.

The others of not correct because they are not equivalent to the ratio 3:5.

Hope this helped!

Find the midpoint: (-1, 9), (7, -1)​

Answers

Answer: (3,4)

Step-by-step explanation:

To find the midpoint, you want to use the formula [tex]m=(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )[/tex]. Since we are given the two points, we can plug them in and solve.

[tex]m=(\frac{-1+7}{2} ,\frac{9+(-1)}{2} )[/tex]            [add numerator]

[tex]m=(\frac{6}{2} ,\frac{8}{2} )[/tex]                          [divide]

[tex]m=(3,4)[/tex]

Now, we know that the midpoint is (3,4).

Answers

Answer:

Step-by-step explanation:

the volume of the triangular prism is 1/2*3.2*5.4*6

Answer:

C

Step-by-step explanation:

The volume (V) of the triangular prism is calculated as

V = Al ( A is the area of the triangular end, l is the length )

A = [tex]\frac{1}{2}[/tex] bh ( b is the base, h the perpendicular height )

Here b = 5.4 and h = 3.2 , thus

A = 0.5 × 5.4 × 3.2 = 8.64 cm² , then

V = 8.64 × 6 = 51.84 cm³ → C

Jasmin, Quinn, and Maddy are rock climbing. Jasmin is 42 ½ feet below Quinn. Maddy is 67 ¾ feet above Jasmin. What is Maddy's position compared to Quinn?

Answers

Answer:

[tex]25\frac{1}{4}[/tex] feet

Step-by-step explanation:

Given

[tex]Maddy = 67\frac{3}{4}[/tex] above Jasmin

[tex]Jasmin = 42\frac{1}{2}[/tex] below Quinn

Required

Determine Maddy's position relative to Quinn's

From the given parameter, one can easily deduce that Quinn is in between Maddy and Jasmin (See attachment)

Using the attachment as a point of reference;

[tex]z = 67\frac{3}{4}[/tex]

[tex]x = 42\frac{1}{2}[/tex]

The relationship between x, y and z is

[tex]z = y + x[/tex]

Make y the subject of formula

[tex]y = z - x[/tex]

Substitute the values of z and x

[tex]y = 67\frac{3}{4} - 42\frac{1}{2}[/tex]

Convert to improper fractions

[tex]y = \frac{271}{4} - \frac{85}{2}[/tex]

Take LCM

[tex]y = \frac{271 - 170}{4}[/tex]

[tex]y = \frac{101}{4}[/tex]

[tex]y = 25\frac{1}{4}[/tex]

Hence; Maddy's position relative to Quinn's is [tex]25\frac{1}{4}[/tex] feet

-Is ZFDE a possible name for the figure below? Explain.

Answers

Answer: Yes [tex]\angle FDE[/tex] is one possible angle name

Another name is [tex]\angle EDF[/tex]

When it comes to naming an angle this way, all we need to worry about is the vertex point. This is where the angle hinges (think of a door or a pair of scissors). In this case, the hinge or vertex point is at point D. The vertex is always the middle letter of any three-letter sequence. The order of the other two points does not matter.

This is why saying "angle FDE" is the same as "angle EDF".

A seat on a Ferris wheel is level with the center of the wheel.The diameter of the wheel is 200 feet. Suppose the wheel rotated 60°, causing the height of the seat to decrease. How much closer to the ground is the seat after the rotation

Answers

Answer: 86.6ft closer to the ground.

Step-by-step explanation:

The diameter of the wheel is 200ft

Then the radius, half of the diameter, is: r = 200ft/2 = 100ft.

Initially, the seat is at the same level that the center of the wheel.

And the distance between the center of the wheel and the bottom is the radius.

Then the initial position is at an angle of 0° from the x-axis. (where the (0,0) of this axis coincides with the center of the wheel=

Now, the wheel rotates 60°. (downwards, so we actually could use -60° measuring from the positive x-axis)

And thinking in this as a triangle rectangle, where the opposite angle is 60°, we can calculate the displacement in the vertical direction as:

y = sin(-60°)*R

y = sin(-60°)*100ft = -86.6ft

So the seat is 86.6ft closer to the ground.

The seat is [tex]86.6feet[/tex] closer to the ground

The seat will be closer by the height it drops when the Ferris wheel turns downwards by [tex]60^{\circ}[/tex].

The height, and the radius of the Ferris wheel form the opposite and the hypotenuse of a [tex]60^{\circ}[/tex] right-angled triangle. Since the diameter of the Ferris wheel is 200feet, the radius will be 100feet. So we have

[tex]sin60^{\circ}=\frac{opp}{hyp}=\frac{h}{100}\\\\h=100\times sin60^{\circ}\\=100\times 0.8660\\=86.6[/tex]

So the seat is [tex]86.6feet[/tex] closer to the ground

The 100 residents are asked if they like to watch basketball and or football. The results are that 98 like to watch basketball, 12 like to watch football, and 2 dislike both. How many like to watch football?

Answers

Answer:

12 people like to watch football

Step-by-step explanation:

The results are that 98 like to watch basketball, 12 like to watch football, and 2 dislike both.

Total number of residents = 100

Basketball (B) = 98

Football(F) = 12

Number of residents that like basketball and football = ( B ∩ F)

2 dislike both

n ( B ∪ F) - People that dislike it = n(B) + n ( F ) - n ( B ∩ F)

100 - 2 = 98 + 12 - n ( B ∩ F)

98 = 110 - n ( B ∩ F)

n ( B ∩ F) = 110 - 98

= 12

Therefore, 12 people like both Football and Basketball

How many like to watch football?

From the above question, we can see that the total number of people that like to watch football = 12 people

What is the upper bound of the function f(x)=4x4−2x3+x−5?

Answers

Answer:

(no global maxima found)

Step-by-step explanation:

Find and classify the global extrema of the following function:

f(x) = 4 x^4 - 2 x^3 + x - 5

Hint: | Global extrema of f(x) can occur only at the critical points or the endpoints of the domain.

Find the critical points of f(x):

Compute the critical points of 4 x^4 - 2 x^3 + x - 5

Hint: | To find critical points, find where f'(x) is zero or where f'(x) does not exist. First, find the derivative of 4 x^4 - 2 x^3 + x - 5.

To find all critical points, first compute f'(x):

d/( dx)(4 x^4 - 2 x^3 + x - 5) = 16 x^3 - 6 x^2 + 1:

f'(x) = 16 x^3 - 6 x^2 + 1

Hint: | Find where f'(x) is zero by solving 16 x^3 - 6 x^2 + 1 = 0.

Solving 16 x^3 - 6 x^2 + 1 = 0 yields x≈-0.303504:

x = -0.303504

Hint: | Find where f'(x) = 16 x^3 - 6 x^2 + 1 does not exist.

f'(x) exists everywhere:

16 x^3 - 6 x^2 + 1 exists everywhere

Hint: | Collect results.

The only critical point of 4 x^4 - 2 x^3 + x - 5 is at x = -0.303504:

x = -0.303504

Hint: | Determine the endpoints of the domain of f(x).

The domain of 4 x^4 - 2 x^3 + x - 5 is R:

The endpoints of R are x = -∞ and ∞

Hint: | Evaluate f(x) at the critical points and at the endpoints of the domain, taking limits if necessary.

Evaluate 4 x^4 - 2 x^3 + x - 5 at x = -∞, -0.303504 and ∞:

The open endpoints of the domain are marked in gray

x | f(x)

-∞ | ∞

-0.303504 | -5.21365

∞ | ∞

Hint: | Determine the largest and smallest values that f achieves at these points.

The largest value corresponds to a global maximum, and the smallest value corresponds to a global minimum:

The open endpoints of the domain are marked in gray

x | f(x) | extrema type

-∞ | ∞ | global max

-0.303504 | -5.21365 | global min

∞ | ∞ | global max

Hint: | Finally, remove the endpoints of the domain where f(x) is not defined.

Remove the points x = -∞ and ∞ from the table

These cannot be global extrema, as the value of f(x) here is never achieved:

x | f(x) | extrema type

-0.303504 | -5.21365 | global min

Hint: | Summarize the results.

f(x) = 4 x^4 - 2 x^3 + x - 5 has one global minimum:

Answer: f(x) has a global minimum at x = -0.303504

Answer:

1A. h = 25/(b + r)

1B. r = 25/h - b

2A. h = r - xy

2B. r = xy + h

Step-by-step explanation:

1. bh + hr = 25

A. h(b + r) = 25

h = 25/(b + r)

B. h(b + r) = 25

b + r = 25/h

r = 25/h - b

2. x = (r - h)/y

A. xy = r - h

h + xy = r

h = r - xy

BC = 12 and AB = 11. Find AC.

Answers

Answer:

AC = 23

Step-by-step explanation:

Assuming A, B, and C are on a line with B in the middle...

We know that AB + BC = AC. Travelling from A to C is the same as travelling from A to B, then B to C, as B is on the way between A and C.

Knowing this, we can set up this equation and add the 2 numbers we know:

AC = AB + BC

AC = 11 + 12

AC = 23


AB + BC = AC
so that would bring the answer to 23

When a car's brakes are applied, it travels 7 feet less in each second than the previous second until it comes to a complete stop. A car goes 28 feet in the first second after the brakes are applied. How many feet does the car travel from the time the brakes are applied to the time the car stops?

Answers

Answer:

70feet

Step-by-step explanation:

during the

1st sec it travels 28 ft

2nd sec =28-7=21ft

3rd sec= 21-7=14ft

4th sec= 14-7= 7ft

last sec=7-7=0ft, at this point the car stops.

so altogether it travels 28+21+14+7+0= 70 feet
