What is the length of AB

Answers

Answer 1

Answer:

12.64

Step-by-step explanation:

cos 53 = Adjacent side/Hypotenuse

cos 53 = Adjacent side/21

21 * cos 53 = (Adjacent side/21) * 21

21 cos 53 = Adjacent side

Adjacent side (AB) ≈ 12.64

Will NAME Brainliest!!

Answers

$9.50. 3.55*2 = 7.1. 7.1 + 2.40 = 9.50

$9.50 is the answer

The price of 1 kilogram of bananas and 2 kilogram of apples is $9.5

What is addition?

Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.

Given:

A kilogram (kg) of bananas costs $2.40.

A kilogram of apples costs $3.55.

So, the price of 2 kilograms of apples cost 2 x 3.55,

= $7.1

To find the price of 1 kilogram of bananas and 2 kilogram of apples:

Addition,

The price = 2.40 + 7.1

The price = $9.5

Therefore, the required price is $9.5.

Through: ( -1,5), parallel to y=-2x+1

Answers

Answer:

y = -2x + 3

Step-by-step explanation:

Parallel Lines:

Parallel lines are lines with the same slope (m), but a different y - intercept (b).

The basic equation of a line is y = mx + b, where m represents slope, and b represents the y - intercept

Solving for the Line:

First solve for the parallel slope of -2

Parallel slope to -2 = -2

Next, input the x and y values given to you by the point to the equation

y = -2x + b

We will input the -1 and 5 for x and y in the equation y = -2x + b

5 = -2(-1) + b

5 = 2 + b

b = 3

The line is y = -2x + 3

Answer:

x = -10

Step-by-step explanation:

Explanation:

Essentially, the function notation, "g(x)" is the same as y.

Given g(x) = 2(x - 5), we could determine x for g(x) = - 30 by substituting -30 as the value of g(x) into the function:

g(x) = 2(x - 5)

-30 = 2(x - 5)

Distribute 2 into the parenthesis on the right-hand side of the equation:

-30 = 2x - 10

Next, add 10 to both sides of the equation:

-30 + 10 = 2x - 10 + 10

-20 = 2x

Finally, divide both sides by 2 to solve for x:

[tex]\LARGE\mathsf{\frac{-20}{\:2}\:=\:\frac{2x}{2}}[/tex]

x = -10Double-check the validity of x = -10:

Verify whether we have the correct value for x by substituting x = -10 into the given function:

g(x) = 2(x - 5)

-30 = 2(-10 - 5)

-30 = -20 - 10

-30 = -30 (True statement).

Answer:

Therefore, the value of x = -10.

Answer: -10 is the answer

x=20

Step-by-step explanation:

the sum of the angles of a triangle is always 180, so we can set up an equation using these angles.

31+90+3x-1=180

collect like terms: 120+3x=180

subtract 120 from both sides

3x=60

divide both sides by 3

b. 17

c. 3x^2, 8x, and 17

Step-by-step explanation:

a. The coefficients of an equation are the numbers that come before the variables, in this case x. We can see there is a 3 multiplying x^2 and an 8 multiplying x, therefore the coefficients would be 3 and 8.

b. The constants are the numerical terms(ones without x). This would be 17.

c. Terms are the products of numbers and/or variables separated by addition or subtraction. These would be 3x^2, 8x, and 17.

Step-by-step explanation:

To find an equation that is parallel, the slopes must be equal. Find the parallel line using the point-slope formula.

Use the slope 2

and a given point (−1,2) to substitute for x1 and y1 in the point-slope form y−y1=m(x−x1), which is derived from the slope equation m=y2−y1x2−x1

y−(2)=2⋅(x−(−1))

Simplify the equation and keep it in point-slope form.

y−2=2⋅(x+1)

Solve for y

The triangle below is isosceles. Find the length of side xx to the nearest tenth.

Answers

Answer:

x = 2

Step-by-step explanation:

Since this is an isosceles triangle the unmarked side is also √2

Since this is also a right triangle use the pythagorean theorem to find x.

x² = (√2)² + (√2)²

x² = 2 + 2

x² = 4

x = 2

The value of x is 2.

What is Pythagoras theorem?

The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

Given:

H= x, P= √2, B= √2

Now, using Pythagoras theorem

H² = P² + B²

x² = (√2)² + (√2)²

x² = 2 + 2

x² = 4

x = 2

Hence, the value of x is 2.
