Find the area of a right triangle with a base of 9 feet and a hypotenuse length of 13 feet and a base of 9 feet.(Round to the nearest tenth.)

Answers

Answer 1

Answer:

Step-by-step explanation:

Remark

The plan is to find the third side. It and the 9 foot side form a right angle. The base is given as 9 feet. The third sid will be the altitutude. The formula is Area = 1/2 * Base * third side.

Formulas

c^2 = b^2 + a^2

Area = 1/2 b * a

Givens

c = 13 feet

a = ?

b = 9 feet.

Answer: 42.2 square feet.

Solution

c^2 = b^2 + a^2

13^2 = 9^2 + a^2

169 = 81 + a^2                 Subtract 81 from both sides.

169 - 81 =81 - 81 + a^2    Combine

88 = a^2                          Take the square root of both sides

√a^2=√88

a = 9.381

Area = 1/2 * 9 * 9.381

Area = 42.21

Rounded to the nearest 1/10 Area = 42.2

The point B is at the centre of the circle.
The points P and Q are on the circumference of the circle.
Calculate the area of the shaded sector.
take π to be 3.142 in your working.
Give your final answer to 1dp

Answers

Answer:

24.7

Step-by-step explanation:

Calculation of the area of the shaded sector is 24.7:

Since

Line PQ = 5.413590865cm

BQ = 9cm

Now

cos(x) = 0.8190928022

x = 35.00591739˚

Now finally the

Area of sector = 24.7cm^2

So point B is at the centre of the circle, making the area of the shaded sector to be 24.7 .

Given the distance Maria ran each day, the total distance she ran during a fifteen ( 15 ) days stretch is 55.5 miles.

What is  multiplication?

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

Here, we have,

Expression for the Total of Distance ran by Maria

Total distance = Distance ran each day × Number days

Given the data in the question;

Distance ran each day by Maria Dm = 3.7miles

Number days ran n = 15days

Total number of distance ran by Maria TDm = ?

Hence, Total distance = Distance ran each day × Number days

TDm = Dm × n

We substitute in our values

TDm = 3.7miles × 15

TDm = 55.5miles

Thus, the distance Maria ran each day, the total distance she ran during a fifteen ( 15 ) days stretch is 55.5miles.

For a grocery store's 25 years anniversary sale they ordered 9 crates of grapes with each create containing 10 bags of grapes. After the anniversary sale they had sold all but 3 bags. How many bags of grapes did they sell during the anniversary?

Answers

Answer:

87

Step-by-step explanation:

9 x 10 = 90, the store had 90 bags in total at the start. 90 - 3 = 87, the store had sold 87 bags of grapes during the anniversary.

The number of bags of grapes that they sell during the anniversary is 87 bags.

What are Arithmetic operations?

Arithmetic operations are the basic part of mathematics which combines the basic operations like addition, subtraction, multiplication and division.

Given that,

For a grocery store's 25 years anniversary sale they ordered 9 crates of grapes with each create containing 10 bags of grapes.

Number of crates of grapes ordered = 9

Number of bags of grapes in each crate = 10 bags.

Total number of bags in 9 crates = 90 bags

After the anniversary sale they had sold all but 3 bags.

Number of bags of grapes sold = 90 - 3 = 87 bags

Hence the number of bags of grapes sold is 87 bags.

A bad contains 15 balls of which X is red. Write an expression for the probability that a ball drawn from the bad is red. When 5 more red balls are added to the bag, the probability becomes 3/4. Find the value of X.

Answers

Answer:

10

Step-by-step explanation:

The current probability of picking a red ball is [tex]\frac{x}{15}[/tex]. When 5 more balls are added, the probability is 3/4. We can write a ratio for this problem:

[tex]\frac{x+5}{15+5} = \frac{3}{4}[/tex]

When using cross multiplication to solve this, you get 3 * 20 = 4(x+5).

60 = 4x + 20

40 = 4x

x = 10 red balls

Answer:

Step-by-step explanation:

To get from 27 to 21, you subtract by 6. To get from 21 to 15, you must also subtract by 6. Therefore, subtracting by 6 is the pattern. In order to get the next number in the sequence, we must subtract 6 from 15.

15 - 6 = 9

The next number is 9. To find the number after 9, we must do the same thing - subtract 6 from 9.

9 - 6 = 3

The 5th number of the sequence is 3.

Answer:

102º

Step-by-step explanation:

So you know that ABC is an Isosceles triangle as AB=AC therefore, angle ABC is equal to angle ACB.

You also know that even though it doesn't look like it, ABP is an equilateral triangle as AB, AP and BP are equal so all those angles must equal 60º.

So:

ABC = 60 - 21 = 39º

and since ABC= ACB

ACB also equals 39º.

Because angles in a triangle add to 180º, BAC is consequently:

180- (39+39) = 180 - 78 = 102º

BAC = 102º

102 degrees because of the angles and lines
