1/2 of the possibilities are even number

Step-by-step explanation:

Add all of the sides together, you get 12, count on even numbers until you get to 12. 2,4,6,8,10,12. that's six numbers which is half of 12. so half of the possibilities are even.

Answer:

  12 ft

Step-by-step explanation:

It is sometimes helpful to start from what you are given and see what develops.

Here, angle B is 30°. That means angle CAB is 60° (the acute angles of a right triangle are complements). AL bisects that 60° angle, meaning two things:

The side ratios of a 30°-60°-90° triangle are 1 : √3 : 2, so AL is 2 times the length of CL.

  AL = 2 × (6 ft) = 12 ft

We know that AL = LB, so LB = 12 ft.

Answer:

The probability of a randomly chosen person being from California is 0.111.

The probability of a randomly chosen person not being from California   is 0.889.

Step-by-step explanation:

The odds of a person, selected from the US population, living in California is 1 to 8.

That is:

\(\text{Odds}(\frac{\text{Lives in California}}{\text{Does not Lives in California}})=\frac{1}{8}\)

Compute the probability of a randomly chosen person being from California as follows:

\(P(\text{Lives in California})=\frac{\text{Odds}(\text{Lives in California})}{\text{Odds}(\text{Lives in California})+\text{Odds}(\text{Does not Lives in California})}\)

                                  \(=\frac{1}{1+8}\\\\=\frac{1}{9}\\\\=0.111\)

The probability of a randomly chosen person being from California is 0.111.

Compute the probability of a randomly chosen person not being from California as follows:

\(P(\text{Love in California})=1-P(\text{Does not Love in California})\)

                                  \(=1-0.111\\\\=0.889\)

Thus, the probability of a randomly chosen person not being from California   is 0.889.

Answer:

45 feet

Step-by-step explanation:

Use ratios:

\(\frac{1}{72}= \frac{7.5}{x}\)

x = 540 inches

divide by 12 to get 45 feet

The wingspan of the actual airplane is 45 feet.

Ratio is the comparison of two quantities having same units.

Example : Ratio of a & b is written as a/b, where b≠0

The scale of the model airplane is 1:72

Let, wingspan of the actual airplane = x inches

Using the ratio formula, we get,

1/72 = 7.5/x

⇒ x = 72×7.5

⇒ x = 540

So, the wingspan of actual airplane = 540 inches = 540/12 feet = 45 feet.

Answer:

7*2/5 it is a improper fraction

Answer:

\(\frac{7}{1}\), \(\frac{2}{1}\), and \(\frac{5}{1}\)

Step-by-step explanation:

Those are all the improper fraction forms of 7, 2, and 5.

Step-by-step explanation:

to\(3w - 7 = \sqrt{8w - 7} \\ {(3w - 7)}^{2} = ({ \sqrt{8w - 7} })^{2} \\ 9 {w}^{2} - 42w + 49 = 8w - 7 \\ 9 { w}^{2} - 42w - 8w + 49 + 7 = 0 \\ 9 {w}^{2} - 50w + 56 = 0 \\ (9w - 14)(w - 4) = 0 \\ w = \frac{14}{9} \: or \: w = 4\)

to make sure the answer

substitute w = 14/9 and w = 4 to the equation.

if w = 14/9

\(3w - 7 = \sqrt{8 w - 7} \\ 3 \times \frac{14}{9} - 7 = \sqrt{8 \times \frac{14}{9} - 7} \\ - \frac{ 7}{3} = \frac{7}{3} \)

we know that if we substitute w = 14/9, the answer is not the same.

if w = 4

\(3w - 7 = \sqrt{ 8 w - 7 } \\ 3 \times 4 - 7 = \sqrt{8 \times 4 - 7} \\ 5 = 5\)

if we substitute w = 4 the answer is the same.. we can conclude the the answer of 3w - 7 = √8w - 4 is 4

The tuxedo was rented for 4 days.

Let's start by assigning variables to the unknowns. Let "x" be the number of additional days rented, and "d" be the total number of days rented (including the first day).

From the given information, we know that the flat fee for the rental is $150, so the cost of the additional days is the total cost minus the flat fee, which is $300 - $150 = $150. We also know that the cost for each additional day is $50. Therefore, we can set up the equation:

$150 + $50x = $300

Subtracting $150 from both sides, we get:

$50x = $150

Dividing both sides by $50, we get:

x = 3

So the tuxedo was rented for 3 additional days, making the total number of days rented:

Answer:

8x + 13

Step-by-step explanation:

"Like terms" means the same kind of algebraic expression...the 6x and the 2x are "like terms" because they both have an x in them. The 9 and the 4 are both constants, which means they are plain numbers. So 6x and 2x is 8x .

9+4 is 13 just like elementary school.

So all together,

6x + 9 + 2x + 4

6x + 2x + 9 + 4

8x + 13

We can rearrange the terms because the problem has all addition in between the terms.

There would have been 4576 cars in the traffic. If SUVs and Trucks are involved in jam, there would be fewer vehicles.

Logical or deductive reasoning involves using a given set of facts or data to deduce other facts by reasoning logically.

Given that, Last Saturday, an accident caused a traffic jam 13 miles long on a stretch of the interstate.

13 miles = 68,640 feet

One car is of 15 ft

Let there be x cars,

15x = 68,640

x = 4576

Therefore,  there are 4576 cars in traffic.

If there are more SUVs and trucks, their length will be more than a car and which will make less number of vehicles involved in the traffic.

Hence, There would have been 4576 cars in the traffic. If SUVs and Trucks are involved in jam, there would be fewer vehicles.

Answer:

\(\frac{dV}{dt}=\frac{B}{3}*\frac{dH}{dt}\)

Step-by-step explanation:

The volume of a pyramid is given by:

\(V=\frac{1}{3}Bh\)

The derivate for the volume expression as a function of height is:

\(\frac{dV}{dh}=\frac{1}{3}B\\\)

We can write that dt/dt = 1. Therefore, the relationship between dV/dt and dh/dt, if B is constant, is given by:

\(\frac{dV}{dh}=\frac{1}{3}B*1\\\frac{dV}{dh}=\frac{1}{3}B*\frac{dt}{dt}\\\frac{dV}{dt}=\frac{B}{3}*\frac{dH}{dt}\)

Let's denote the amount Jolene invested at 3 percent interest as 'x' dollars. Since she put twice as much in the lower-yielding account, the amount she invested at 9 percent interest would be '2x' dollars.

To calculate the interest earned from each account, we'll use the formula: Interest = Principal × Rate × Time.

For the 3 percent interest account:

Interest_3_percent = x × 0.03

For the 9 percent interest account:

Interest_9_percent = 2x × 0.09

We know that the total annual interest is $3120, so we can set up the equation:

Interest_3_percent + Interest_9_percent = 3120

Substituting the above equations, we have:

x × 0.03 + 2x × 0.09 = 3120

Simplifying the equation:

0.03x + 0.18x = 3120

0.21x = 3120

Dividing both sides of the equation by 0.21:

x = 3120 / 0.21

x = 14857.14

Therefore, Jolene invested approximately $14,857.14 at 3 percent interest and twice that amount, $29,714.29, at 9 percent interest.

Answer:

Step-by-step explanation:

X is the amount invested at 6%

Y is the amount invested at 9%

0.06X + 0.09Y = 4998

X = 2Y

0.06(2Y) + 0.09Y  = 4998

.12Y + 0.09Y = 4998

0.21Y = 4998

21Y = 499800

Y = 499800/21 = 23800

So X = 2*23800 = 47600

$47,600 is invested at 6% and $23800 is invested at 9%

Answer:

The correct option is the third one counting from the top. (5892 m^2)

Step-by-step explanation:

First, we need to remember that:

For a rectangle of length L and width W, the area is:

A = L*W

For a circle of diameter D, the area is:

A = pi*(D/2)^2

Where pi = 3.14

In the image, we can see a rectangle and half a circle, the total area of the image will be equal to the area of the rectangle plus the area of the half circle.

In the image, we can see a rectangle of length L = 100m and width W = 50m

Then the area of the rectangle is:

A = 100m*50m = 5000m^2

And we can see that for the half-circle the diameter is D = 50m

Note that the area of a half-circle is half of the area of a complete circle, then the area of that half-circle is:

A = (1/2)*(3.14*(50m/2)^2) = 981.25 m^2

If we add these two areas we get:

Total area =  5000m^2 + 981.25 m^2 = 5981.25 m^2

If we round it up, we get:

Total area = 5982 m^2

The correct option is the third one counting from the top.

Answer:

To find 29% of 150, we can first express 29% as a decimal by dividing 29 by 100. 29% is the same as 0.29.

Then, we multiply 0.29 by 150 to find the answer:

0.29 * 150 = 43.5

So, 29% of 150 is equal to 43.5.

Here's the work:
