Frankie solved the following inequality -2x-7>17 and stated that -5, 1, and 2 are in the solution set. what possible mistakes did frankie make? justify your response by explaining the steps you took in solving the inequality.

Answer:

The son overtakes the father 3 hours after the father started driving which is 2 hours after the son started driving.

Step-by-step explanation:

Father:

speed = 48 km/h

distance = d

time = t

Son:

speed = 72 km/h

distance = d

time = t - 1

speed = distance/time

distance = speed × time

Father:

d = st

d = 48t

Son:

d = st

d = 72(t - 1)

d = 48t

d = 72(t - 1)

48t = 72(t - 1)

48t = 72t - 72

72 = 24t

t = 3

The son overtakes the father 3 hours after the father started driving which is 2 hours after the son started driving.

Applying the inscribed angle theorem, the missing measures are:

measure of arc TR = 106°

measure of arc TL = 74°

m∠L = 50°

m∠R = 37°

m∠RTV = 37°

Here, we have,

The Inscribed Angle Theorem

Measure of an inscribed angle = half the measure of the arc it intercepts

Central angle = measure of intercepted arc

We are given the following:

LR and TV are diameters of the circle O.

m∠TOR = 106° (central angle)

Find measure of arc TR:

measure of arc TR = m∠TOR

measure of arc TR = 106°

Find measure of arc TL:

measure of arc TL = 180° - m∠TOR

measure of arc TL = 180° - 106°

measure of arc TL = 74°

Find m∠L:

m∠L = ½(measure of arc TR)

m∠L = ½(106°)

m∠L = 50°

Find m∠R:

m∠R = ½(measure of arc TL)

m∠R = ½(74°)

m∠R = 37°

Find m∠RTV:

m∠RTV = ½(measure of arc RV)

m∠RTV = ½(180 - 106)

m∠RTV = ½(74)

m∠RTV = 37°

Analysis of Jake's free-throw data shows that it is positively skewed, indicating that he most frequently scores around 17-18 points per game, with fewer games with lower scores.

To visualize and understand Jake's free-throw data, we can create a histogram. First, we'll list the range of shots made per game. These are: 8, 9, 10, 11, 12, 15, 16, 17, 18, and 19. Then, for each number, count how many times it occurs in the data set. The distribution could look something like this:

We have,

When we say a tank is 284 cubic feet, we mean that the tank has a volume of 284 cubic feet.

When we measure the volume of a three-dimensional object like a tank, we typically use a unit of measures like cubic feet or cubic meters.

A cubic foot is the volume of a cube that measures 1 foot on each side.

So if we say a tank has a volume of 284 cubic feet, we mean that if we were to take a cube that measures 1 foot on each side and stack 284 of those cubes together, we would have a tank with the same volume as the resulting cube.

The proportion of observations greater than 7 is 0.25 or 25%.

For this question, we need to identify the number of observations higher than 7.

After inspecting the dataset, 25 values can be seen that are greater than 7.

Then, the proportion of observations greater than 7 can be calculated as follows:

proportion = number of observations greater than 7 / total number of observations

proportion = 25 / 100

proportion = 0.25

Therefore, the proportion of observations greater than 7 is 0.25 or 25%.

If a gasoline pump delivers 4 gallons of gas per minute, proportionately, it will take it 4 minutes to fill a gas tank that holds 16 gallons.

Proportion refers to the ratio of one unit or quantity compared to another unit or quantity.

Proportions are represented as fractional values using decimals, fractions, and percentages.

The time it takes the gasoline pump to deliver 4 gallons = 1 minute

Proportionately, to deliver 16 gallons, the time = 4 minutes (16 ÷ 4)

Step-by-step explanation:

3 × [tex]\frac{1}{10}[/tex]  is [tex]\frac{3}{10}[/tex].  This is the same as .3 when it's written in decimal form.

The first place on the right side of the decimal is the 'tenths' place. The second spot on the right side of the decimal is the 'hundredths' place.

Like this:

hundreds   tens   ones   .  tenths   hundredths   thousandths

All of the answers have the 830 in them. The only difference between the answers is the .380, .308, .038, .083. Once you see you have 3/10 (which is said three-tenths, which is .3) you can eliminate the last two answers, c and d. Then check the hundredths place. You have 8/100 (which is said eight-hundredths, which is .08) then you can eliminate b and find your answer, a.

Answer: Given, sin θ = √2/6

We know that sin^2θ + cos^2θ = 1

Solving for cos θ, we get:

cos θ = ±√(1 - sin^2θ)

cos θ = ±√(1 - (2/6)^2)

cos θ = ±√(1 - 1/9)

cos θ = ±√(8/9)

Since θ is acute, cos θ is positive. Hence,

cos θ = √(8/9) = (2√2)/3

We know that tan θ = sin θ / cos θ

tan θ = (√2/6) / [(2√2)/3]

tan θ = √2/4

We know that cot θ = 1/tan θ

cot θ = 1/ (√2/4) = (2√2)/2 = √2

We know that csc θ = 1/ sin θ

csc θ = 1/ (√2/6) = (6√2)/2 = 3√2

We know that sec θ = 1/ cos θ

sec θ = 1/[(2√2)/3] = (3√2)/2

Hence, the exact values of the remaining trigonometric functions of the angle θ are:

cos θ = (2√2)/3

tan θ = √2/4

cot θ = √2

csc θ = 3√2

sec θ = (3√2)/2

Answer :

Step-by-step explanation:

It's given that, Area of square is 595.36 square feet.

As we know that area of square is calculated by,

Substituting the values,

595.36 = side

side =√595.36

side = 24.4 feet

Hence, the side of the square is 24.4 feet.

Now,

Perimeter (square) = 4 × side

Perimeter = 4 × 24.4

Perimeter = 97.6 feet

Therefore, The perimeter of the square is 97.6 feet

Answer:

97.6 ft

Step-by-step explanation:

we know a square has 4 equal sides.
Area of a square = side X side or side squared

Plug in the value of area

595.36 square feet = side squared

24.4 ft = side ( do square root in both sides)

Perimeter of an square= side + side + side + side or 4 X side

That’s 4 X 24.4 ft = 97.6 ft.

The distance  between of the belt buckle from the ground is 2.40 feet.

The diameter of the head is 3 3/4 inches.

A scale drawing is either an enlarged or reduced image of another image or object. A scale drawing is enlarged or reduced using a scale. A scale is a used to determine the ratio between the scale drawing and the original diagram.

The distance between of the belt buckle from the ground in real life would be greater than that of the scale drawing. Also, the diameter of the head would be larger in real life.

Distance  between of the belt buckle from the ground = 12 / 5 = 2.40 feet

In order to determine the diameter of the scale head, first convert inches to feet.

1 inch = 1/12 feet

The value of x in the equation 9x In x + x = 0 is x = 0.895

From the question, we have the following parameters that can be used in our computation:

9x In x + x = 0

To calculate the value of x, we start by dividing through the equation by x

So, we have the following representation

9 In x + 1 = 0

Subtract 1 from both sides of the equation

This gives

9 ln x = -1

Divide both sides by 9

ln x = -1/9

So, we have

x = e^(-1/9)
