Answer:

Since 80 and 40 are both divisible by 40 and 10, 40 and 10 are factors of both 80 and 40.

Step-by-step explanation:

The approximate air pressure at the center of a hurricane is 910 millibars.

Given,

The mean sustained wind velocity equation, v = 6.3 × √(1013 - p)

p is the air pressure in millibars

The mean sustained wind velocity - 64 meters per second.

We have to find the approximate air pressure.

Here,

The equation for wind velocity ;

v = 6.3 × √(1013 - p)

v is given 64

Then substitute;

64 = 6.3 × √1013 - p

64/6.3 = √1013 - p

10.16 = √1013 - p

Square both sides

(10.16)² = (√1013 - p)²

We get,

103.23 = 1013 - p

p = 1013 - 103.33 = 909.67 ≈ 910 millibars

That is,

The approximate air pressure at the center of a hurricane is 910 millibars.

ok... this is a very unusually presented question...

it really does not depict any of the typical "math properties" (associative, communitive property, etc)

what is goin on here is "the distributive property" ... more specifically "factoring/ distributive property...

if you factor out the common 0 (zeros) from the two groups, you

end up with 0 x (3+9)  

so factoring/ distributive property should be the answer

Step-by-step explanation:

Restaurant Distributing offers a commercial pasta maker for 980 with a trade discount of 25%. This means the company is offering to sell the product at the price calculated below;

However, a competitor is offering to sell at $661.50. This means the discount to be offered should be equal to 980 - 661.50. Hence the new discount amount shoud be $318.50. Therefore the additional discount would be calculated as follows;

This means, rather than offering a discount of 25%, Restaurant distributing should offer an additional discount of 32.5 - 25 which gives you 7.5%

Answer:

8b

Step-by-step explanation:

You can factor the b-term out since b-term exists for all terms in the expression. By factoring out, you are basically dividing the factored term off and put it outside of the bracket, thus:

\(\displaystyle{16b-8b=\left(16-8\right)b}\)

Then evaluate and simplify:

\(\displaystyle{\left(16-8\right)b=8\cdot b}\\\\\displaystyle{=8b}\)

The x-intercept is 12 and represents the number of pieces and the y-intercept is 48 and represents the initial length.

A straight line on the coordinate plane is represented by a linear function.

In another word, a linear function is a function that varies linearly with respect to the changing variable.

As per the given function,

y = 48 - 4x

At x-intercept, y = 0

48 - 4x = 0

x = 12

Since x is the number of cuts so it represents that we can cut 12 pieces.

At y-intercept , x = 0

y = 48

Since 48 is the initial length so it represents the initial length.

Hence "The beginning length is represented by the y-intercept, which is 48, and the number of pieces is represented by the x-intercept, which is 12".

As each trial has a 0.375 probability, the probability for three successes is 0.05273 and for six successes is 0.00278.

Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, if we are unclear of how an event will turn out. Statistics is the study of occurrences subject to probability. The number of possible outcomes is divided by the total number of possible outcomes to determine probability. Odds are not the same as probability. Odds are calculated by dividing the probability of a given event by the probability that it won't. By dividing the number of preferable outcomes by the total number of potential outcomes, probability, which measures the likelihood that an event will occur, is obtained.

Here,

The probability of success in each trial=3/8

For 3 success,

P(3)=(3/8)³

=0.05273

For 6 success,

P(6)=(3/8)⁶

=0.00278

The probability for 3 success is 0.05273 and for 6 success is 0.00278 as for each trial, the probability is 0.375.

The dimensions of the lawn are 24 meters by 16 meters or 32 meters by 12 meters.

Let's start by considering the formula for the perimeter of a rectangle. The perimeter of a rectangle is the sum of the length of all its sides, which can also be written as 2 times the length plus 2 times the width. In this case, we know the total fence length, which is 88 meters. Therefore, we can write the equation as:

2L + 2W = 88 ------(1)

Next, we are given the area of the rectangle, which is 384 square meters. The formula for the area of a rectangle is length multiplied by width. Therefore, we can write:

L x W = 384 ------(2)

We now have two equations with two unknowns. We can solve this system of equations by substitution or elimination method. Let's use the substitution method to solve this problem.

From equation (1), we can express L in terms of W as:

L = (88 - 2W)/2

Substituting this value of L into equation (2), we get:

(88 - 2W)/2 x W = 384

Simplifying the equation, we get:

44W - W² = 384 x 2

Rearranging and simplifying further, we get:

W² - 44W + 768 = 0

We can now solve this quadratic equation to find the value of W. Factoring the equation, we get:

(W - 24) (W - 32) = 0

Therefore, W can be either 24 meters or 32 meters. We can find the corresponding value of L using equation (1).

When W = 24, L = (88 - 2 x 24)/2 = 20 meters

When W = 32, L = (88 - 2 x 32)/2 = 12 meters

Answer:

7a) $600

7b) $468

9) $1450

Step-by-step explanation:

Q7. (a) This question is on the topic of percentage, whereby we are required to find what certain percentages of the total represents. We are given that Tania payed 22% of the cost of health care, which is also equivalent to $132. The question requires us to find the total value of her health care, which means 100% of her health care.

22% ----- $132

Divide both sides by 22:

1% ----- $132 ÷22= $6

Multiply both sides by 100%:

100% ----- $6 ×100= $600

Thus, her health care costs $600 in total.

__________

Q7. (b) Tania's employer payed 78% of her health care cost, which is also the remaining amount which Tania did not pay. Thus the amount paid by the employer can be found by calculating 78% of Tania's healthcare cost or by subtracting the amount paid by Tania from the total healthcare cost.

Amount paid by employer

= $600 -$132

= $468

Alternatively,

amount paid by employer

= 78% of healthcare cost

= 78(1% of healthcare cost)

= 78($6)

= $468

Thus, the employer contributed $468 for her healthcare.

Q9. The gross pay is the sum of his regular pay and his overtime pay. Let's find the number of hours he worked overtime.

Total hours worked

= regular hours +overtime hours

= 52 hours

Number of regular hours= 40

Number of overtime hours

= 52 -40

= 12

We are given that the overtime pay is 1.5 times the regular payment.

Overtime pay per hour

= 1.5(regular hourly pay)

= 1.5($25)

= $37.50

Gross pay

= (number of regular hours)(regular hourly pay) +(number of overtime hours)(overtime hourly pay)

= 40($25) +12($37.50)

= $1000 +$450

= $1450

Thus, Ricardo's gross pay is $1450.

Josh will pay a loan origination fee of $2,100 if the lender charges a fee of 0.75%.

To calculate the loan origination fee, we need to multiply the loan amount by the lender's fee percentage.

Loan origination fee = Loan amount x Lender's fee percentage

In this case, the loan amount is $280,000 and the lender's fee percentage is 0.75%.

Loan origination fee = $280,000 x 0.0075

Loan origination fee = $2,100

Step-by-step explanation:

Ok, so this is simple. First you multiply the three on the outside by the x and 2 on the inside using the distributive property. Then you should get 3x (3 times x) + 6 (3 times 2). now that you have 3x+6=12, you can subtract the 6 from both sides. you should end up with 3x=6. To figure out x you should divide both sides by 3. You should end with x = 2.

3(x+2)=12

The total monthly house payment is more than 28% of the adjusted monthly income, Guenther doesn't qualify for this mortgage. We found out the solution in the following manner.

The monthly income of the Guenther is = $3200

Adjusted monthly income = M = 3200-335 = $2865

The loan principal P=$150,000

Interest rate i = 5% pa = (5/12)%pm

Loan term = n = 15*12=180 months

Equated monthly installment EMI=  (P * r * (1+r)^n) /(1+r)^n -1

EMI = (150,000 * 0.042 * (1.0042)¹⁸⁰)/  (1.0042)¹⁸⁰- 1

EMI = $1189.32

Total monthly house payment =T= 1189.32+225 = $1414.32

(T/M)x100 = (1414.32/2865)x100 = 49.37%

Since the total monthly house payment is more than 28% of the adjusted monthly income, Guenther doesn't qualify for this mortgage.
