Consider the original parallelogram and the reduction.

What is the length of side A in the new parallelogram?

Answers

Given:

The given figure represents the original parallelogram and the reduction.

To find:

The length of side A in the new parallelogram.

Solution:

We know that the original figure is always similar to its reduction. So, both parallelograms are similar to each other.

The corresponding sides of similar figures are proportional.

[tex]\dfrac{45}{18}=\dfrac{5}{A}[/tex]

[tex]45\times A=5\times 18[/tex]

[tex]45A=90[/tex]

Divide both sides by 45.

[tex]A=\dfrac{90}{45}[/tex]

[tex]A=2[/tex]

The length of side A in the new parallelogram is 2 cm. Therefore, the correct option is A.

A coffee is sitting on Mr. Hunt's desk cooling. It cools according to the function T=70(0.80)^x+20, where x is the time in minutes and T is the temperature in degree Celsius.

Answers

Answer:

90 degrees

Step-by-step explanation:

Complete question

A coffee is sitting on Mr. Hunt's desk cooling. It cools according to the function T=70(0.80)^x+20, where x is the time in minutes and T is the temperature in degree Celsius. WHAT IS THE INITIAL temperature of the coffee

The initial temperature occurs at x = 0

Substitute x = 0 into the expression;

T=70(0.80)^x+20

T =70(0.80)^0+20

Since any value raise to power of zero is 1, hence;

T = 70(1)+20

T = 70+20

T = 90 degree Celsius

Hence the initial temperature of the coffee is 90 degrees

The initial temperature of the coffee is 90 degrees.

The function is represented as:

[tex]\mathbf{T = 70(0.80)^x + 20}[/tex]

At the initial temperature, x = 0.

So, we have:

[tex]\mathbf{T = 70(0.80)^0 + 20}[/tex]

Expand

[tex]\mathbf{T = 70 \times 1 + 20}[/tex]

Multiply

[tex]\mathbf{T = 70 + 20}[/tex]

Add

[tex]\mathbf{T = 90}[/tex]

Hence, the initial temperature of the coffee is 90 degrees.

Answers

I think it’s A hope it help

Answer:

Event B has the smallest probability and Even C has the greatest probability

Step-by-step explanation:

There are more odd number greater than 50 than odd numbers less than 20

So the probability of selecting an odd number greater than 50 is greater than the probability of selecting an odd numbers less than 20

There are more even numbers than odd numbers greater than 50

So the probability of selecting an even number is greater than the probability of selecting an odd number greater than 50

Answers

Answer:

Y= -2/5X

Step-by-step explanation:

the equation is y=mx + b

slope: -2/5x

y- intercept: 0

all you do is combined your slope and y-intercept together: Y= -2/5X , you dont need to add +0 because it gonna just still be the same as y= - 2/5x

Y= -2/5X or y= -2/5x + 0 is the same so it can be any of these 2 that you pick but the correct way is y= -2/5x

Answer: 2 independent sample test of proportions

Step-by-step explanation:

The teo independent sample test of proportion is also referred to as the two proportion z-test and it simply allows the researcher to compare the two proportions in order to ascertain if they're the same or not.

In this case, the null hypothesis will be that that the proportions given in the research are the same while the alternate hypothesis will be that there is a difference between the proportions given.

The kind of analysis that would be most adequate for the given study:

Test of 2 Independent Proportions.

Independent Proportions

The test of two independent proportions is characterized as the method of study in which samples are opted randomly and allowed to remain independent.

In such a study, a minimum of 5 failures and successes are considered to reach a conclusion.

What is Pythagorean Theorem?

Pythagorean Theorem is well known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.

Now,

In option A;  

It states about the Pythagorean Theorem,

Pythagorean theorem is well known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.

Hence, option A is true.

In the option B; converse of Pythagoras theorem states that;

In the cryptarithm shown with sum 700, different letters stand for different digits, and no letter represents the digit 7 or 0. How many different numeric values for "SAT" are possible?


SAT+SUN=700

Answers

Answer:

The number of possible numeric value for SAT are 8 possible numeric values

Step-by-step explanation:

A cryptarithm is a form of mathematical game where unknown numbers represented by letters of the alphabet are used to form mathematical equations

The given cryptarithm is SAT + SUN = 700

The parameters are;

The digits represented by the letters are different

Non of the digits represented by the letters equals 7 or 0

We have;

T + N = 10

1 + A + U = 10

1 + S + S = 7

Therefore, S = (7 - 1)/2 = 3

S = 3

A + U = 10 - 1 = 9

A + U = 9

Therefore, A = 4 or 5 (2 choices)

From T + N = 10

T = 1, 2, 8, or 9 (4 choices) similarly, N = 1, 2, 8, or 9 (4 choices)

Therefore, the number of numeric values that SAT represent is given as follows;

(S = 1 choice) × (A = 2 choices) × (T = 4 choices) = 1 × 2 × 4 = 8 numeric values

SAT has 8 possible numeric value

60% of the vehicles owned by a transport company are trucks, 15% are vans and the rest are buses. If there are 10 buses, how many trucks are there?

Answers

Answer:

Hope this help, pls mark me as Brainliest!

Step-by-step explanation:

60% = 0.6

15% = 0.15

10 = 0.15

Answer:

24

Step-by-step explanation:

Let x represent total number of vehicles

Let T represent number of trucks

Let V represent number of vans

Let B represent number of buses

Convert percent's to decimals:

60% = 0.6

15% = 0.15

Set up equations:

T = 0.6x

V= 0.15x

B= (1 - 0.6 - 0.15)x

For buses, the remaining portion of the 100% of vehicles is 100% -60% -15%

Since we know there are 10 buses, set B=10

B= (1 - 0.6 - 0.15)x

10= (1 - 0.6 - 0.15)x

10= 0.25 x

Divide both sides by 0.25 so that we get:

10/0.25 = x

x= 40

We now know there are 40 vehicles present.  To find the number of trucks, we take 60% of the total number of vehicles

T = 0.6x

T= 0.6 (40)

T= 24

Therefore there are 24 trucks.

A shopkeeper purchased hammocks for $800 and sold them at a discount of 25%. What was the selling price? Choose the correct option.

A $400

B $600

C $200

D $500

Answers

Answer:

B

Step-by-step explanation:

25% of 800 is 200, so 800-200 is 600

The selling price of the hammocks is $600.

What is selling price?

Selling price is the price that a customer pays to purchase a product or a commodity.

What is cost price?

Cost price is the total amount of money that it costs a manufacturer to produce a given product or provide a given service.

What is discount?

A reduction made from the gross (see gross entry 1 sense 3b) amount or value of something is called discount.

What is the relation between cost price, selling price and discount?

selling price = cost price - discount

According to the given question.

The cost price of hammocks = $800

The percentage of discount given by the shopkeeper for the hammock = 25%.

So,

The amount discount given by the shopkeeper

= 25% of 800

[tex]= \frac{25}{100} (800)\\[/tex]

= $200

Therefore, the selling price of the hammocks = $800 - $200 = $600

Hence, the selling price of the hammocks is $600.
