Answers

Answer 1

Answer:

3 faces

A cylinder has 3 faces - 2 circle ones and a rectangle (if you take the top and bottom off a tin can then cut the cylinder part on the seam and flatten it out you would get a rectangle). It has 2 edges and no vertices (no corners).

Plot G(8,-6) , H(2,-6) , J(7,4) , and K(7,10) in a coordinate plane. Are GH and JK congruent?

Answers

Answer:

Yes GH ≅JK

Step-by-step explanation:

The line GH and JK are congruent because they measures are equal.

JK line is vertical so the x-coordinate is constant and the difference in y is 10-4 = 6 and

GH line is horizontal so the y-coordinate is constant and the difference in x is 8-2 = 6

Outlier Is the answer you are looking for

The red arrow represents an outlier in the given dot plot. which the correct answer would be an option (A).

What is the dot plot?

A dot plot, sometimes known as a dot chart, is a sort of basic histogram-like graphic used in statistics for very small data sets with discrete values.

An outlier is a value in a random sampling from a population that is significantly different from the other values. In some ways, this definition leaves it up to the analyst (or a consensus process) to determine what is abnormal. Normal observations must first be characterized before anomalous observations may be identified.

The dot plot is given in the question,

According to the given dot plot,

Most data are clustered around [12, 14], while 24 is distant from this interval.

Thus, the red arrow represents an outlier in the given dot plot.

Hence, the correct answer would be option (A).

Step-by-step explanation:

x : 5 = 12 : 21

Cross multiply,
21 *x = 5*12

21x = 60

x = 60/21

Step-by-step explanation:

Given proportionality:

x : 5 = 12 : 21

We know that:

Product of means = product of extremes

Means : 5,12

Extremes : x,21

5 × 12 = x × 21

60 = 21 x

Divide both sides by 21

Answers

The amount you would pay altogether if you borrow $500 for  5 years at

an annual interest rate of 7% is $945.

How much would you pay altogether?

The amount you would pay altogether is the sum of the amount borrowed and the interest.

Total value of the debt = interest + amount borrowed

Interest = $700 x 7% x 5 = $245

Total value of the debt = $245 + $700 = $945

If g(x) is the inverse of f(x), then by definition of inverse function,

f(g(x)) = g(f(x)) = x

Given that f(x) = 5x - 4, we have

The volumes of the pyramids are listed below:

V = 1437.333 cm³V = 75,398 km³V = 59.2 ft³V = 393.3 yd³V = 1134.116 m³V = 403.333 mm³V = 405.6 in³V = 886.808 ft³How to determine the volume of a pyramid

Volume is the space occuppied by an object. In this question we must determine the volumes of pyramids of circular base and polygonal base (V). All the formulas needed are described below:

Volume of the pyramid

V = (π/3) · B · h     (1)

Base of the pyramid - Circle

B = (π/4) · R²     (2)

Base of the pyramid - Regular polygon

B = (n · L²)/(4 · tan 0.5α)     (3)

Base of the pyramid - Right triangle

B = (1/2) · b · z     (4)

Base of the pyramid - Rectangle

B = b · z

Where:

R - Radiusn - Number of sides of the polygon.l - Side lengthα - Internal angle, in degree.h - Height of the pyramidb - Base of the right triangle/rectangle.z - Length of the right triangle/rectangle.

Now we proceed to solve each pyramid:

1) Square, n = 4, α = 90°, L = 14 cm, h = 22 cm

B = 196 cm², V = 1437.333 cm³

2) Circle, R = 3 km, h = 8 km

B ≈ 28.274 km², V = 75,398 km³

3) Right triangle, b = 12 ft, z = 3.7 ft, h = 8 ft

B = 22.2 ft², V = 59.2 ft³

4) Rectangle, b = 23 yd, z = 9 yd, h = 5.7 yd

B = 207 yd², V = 393.3 yd³

5) Circle, R = 9.5 m, h = 12 m

B ≈ 283.529 m², V = 1134.116 m³

6) Regular pentagon, B = 110 mm², h = 11 mm

V = 403.333 mm³

7) Square,n = 4, α = 90°, L = 13 in, h = 7.2 in

B = 169 in², V = 405.6 in³

8) Regular triangle, n = 3, α = 120°, L = 16 ft, h = 24 ft

B ≈ 110.851 ft², V = 886.808 ft³

Answers

Answer:

3.55,11.25,48.20,49.413,42.184

Step-by-step explanation:

$3,500 + 0.05% = $3.55

$1,250 + 0.010% = $11.25

$25,340 + $22,860 = $ 48.20

The graph of a linear equation has a slope of 4 and an x-intercept at (2, 0). What is the y-intercept of the graph?

Answers

Answer:

y-intercept = -8

Step-by-step explanation:

Slope-intercept form of a linear equation: y = mx + b

(where m is the slope and b is the y-intercept)

Given:

slope (m) = 4point (x₁, y₁) = (2, 0)

Substituting the given values into the slope-point form of a linear equation:

[tex]\sf y-y_1=m(x-x_1)[/tex]

[tex]\implies \sf y-0=4(x-2)[/tex]

[tex]\implies \sf y=4x-8[/tex]

Comparing the final equation with the Slope-intercept form of a linear equation, we can see that the y-intercept is -8

Elaine drives her car 70 miles and has an average of a certain speed. If the average speed had been 3mph more, she could have traveled 77 miles in the same length of time. What was her average speed

Answers

Answer:

30 miles/hr

Step-by-step explanation:

d / r  = time     distance divided by rate = time

70 / r   = time     and    77/(r+3 ) = time       r = her original average speed

 'time' is the same for both so we can equate the equations

70/r = 77/(r+3)     cross multiply

70r + 210 = 77r

7r = 210

r = 30 m/hr

x is an integer.
The Lowest Common Multiple (LCM) of x and 12 is 120
The Highest Common Factor (HCF) of x and 12 is 4
Work out the value of x

Answers

Since 120 = 12 • 10 and LCM(x, 12) = 120, these suggest x is some multiple of 10.

HCF(x, 12) = 4 tells us that x is a multiple of 4.

If x is a both a multiple of 4 and 10, then the smallest x that fits both conditions is 4 • 10 = 40. (-40 also satisfies the criteria.)

The value of x for which the LCM and HCF of x and 12 are 120 and 4 respectively is 40.

What do we mean by Lowest Common Multiple (LCM) and Highest Common Factor (HCF)?

The Lowest Common Multiple (LCM) of the numbers is the smallest common multiple of the given numbers.

The Highest Common Factor (HCF) of the numbers is the greatest factor of the given numbers.

In the case of two numbers, the product of LCM and HCF is equal to the product of the numbers.

How do we solve the given question?

We are given two numbers, x and 12.

Their LCM and HCF are 120 and 4 respectively.

We are asked to find the number x.

For two numbers, we know that the product of two numbers is equal to the product of their HCF and LCM.

∴ x*12 = 120*4

or, 12x = 480

or, x = 480/12

or, x = 40.

∴ The value of x for which the LCM and HCF of x and 12 are 120 and 4 respectively is 40.

Assume that 60% of the students at Remmington High studied for their Psychology test. Of those that studied, 25% got an A, but only 8% of those who didn't study got an A. What is the approximate probability that someone that gets an A actually studied for the Psychology test

Answers

The probability that someone that gets an A actually studied for the Psychology test is 0.15 or 15% if 60% of the students at Remmington High studied for their Psychology test. Of those that studied, 25% got an A, but only 8% of those who didn't study got an A.

What is probability?

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Let A = the students get an A

Let B = the student's studied for the psychology test

We know that probability:

P(B) = 60% = 0.60  and

P(A/B) = 25% = 0.25

We know that:

[tex]\rm P(A/B) = \frac{P(A\cap B)}{P(B)} = 0.25[/tex]

Now the probability that someone that gets an A actually studied for the Psychology test:

P(A∩B) = P(B) ×0.25

P(A∩B)  = 0.60×0.25

P(A∩B)  = 0.15

Thus, the probability that someone that gets an A actually studied for the Psychology test is 0.15 if 60% of the students at Remmington High studied for their Psychology test. Of those that studied, 25% got an A, but only 8% of those who didn't study got an A.
