Answers

Answer 1

Answer:

B

Step-by-step explanation:

sinA=opp/hyp

sinA=16/20=4/5

cosA=adj/hyp

cosA=12/20=3/5

Answer 2

Answer:

We found sinA= 3/5 and cosA=4/5

Option A is correct.

Step-by-step explanation:

The formula to find sin A is :

[tex]sin A = \frac{Perpendicular}{Hypotenuse}[/tex]

while the formula to find cos A is:

[tex]cosA=\frac{Base}{Hypotenuse}[/tex]

So, in the figure given:

Base = 16

Perpendicular = 12

Hypotenuse = 20

Now, finding sin A and cos A using formulas and above values

[tex]sin A = \frac{Perpendicular}{Hypotenuse}\\sin A = \frac{12}{20}\\sinA=\frac{3}{5}[/tex]

[tex]cosA=\frac{Base}{Hypotenuse}\\cosA=\frac{16}{20}\\cosA=\frac{4}{5}[/tex]

So, we found sinA= 3/5 and cosA=4/5

Option A is correct.

needs to makes 6 batches, how many cups of flour will
she need for all six batches?

Answers

Answer:

9

Step-by-step explanation:

It is very simple, 3/4 * 2 = 1.5

If we take 1.5 and multiply it by the amount of batches being made (6), we will have our answer.

1.5*6 = 9, so there we have our answer.

3y−3x=21 Put the following equation of a line into slope-intercept form, simplifying all fractions.

Answers

Answer:

y = x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c )

Given

3y - 3x = 21 ( add 3x to both sides )

3y = 3x + 21 ( divide all terms by 3 )

y = x + 7 ← in slope- intercept form

There are two numbers that are twice as far away from 13 than 22. The sum of those numbers are?

Answers

Answer:

Sum of those numbers are 50

Step-by-step explanation:

Let x represent a number that is twice as far away from 13 than 22.

The number can't be less than 13 but will be between 13 and 22 or slightly more than 22 otherwise it will be far away from both.

Thus;

|x - 13| = 2|x - 22|

It's in absolute form, so we will square both sides to get rid of the absolute brackets.

Thus;

(x - 13)² = 4(x - 22)²

x² - 26x + 169 = 4(x² - 44x + 484)

x² - 26x + 169 = 4x² - 176x + 1936

4x² - x² - 176x + 26x + 1936 - 169 = 0

3x² - 150 + 1767 = 0

Using quadratic formula, we have;

x = 19 or x = 31

Thus,the sum of the 2 numbers = 31 + 19 = 50

Hernando ate 2/8 of a pizza for a dinner. he gave his 6 friends the rest of the pizza, and told them to share equally. To determine the fraction of the whole pizza that each of his friends received, Hernando performed the calculations below.
6/8 divided by 6= (6 divided by 6)/8= 1/8
he concluded that each person received 1/8 of the whole pizza. Are Hernando's calculations correct?

O yes they are correct. Hernando divided 6 by 6
O yes they are correct. Hernando divided 2/8 by 6
O No they are not correct. Hernando should have multiplied by 6, not divided by 6

Answer:

yes they are correct. Hernando divided 6 by 6

Step-by-step explanation:

Hernando ate 2/8 of a pizza for a dinner.

he gave his 6 friends the rest of the pizza, and told them to share equally.

Rest pizza portion=1-2/8

=6/8

6/8 pizza divided into 6 person

6/8÷6

1/8

So 1/8 portion get each person

So the option a is correct

yes they are correct. Hernando divided 6 by 6

What is Linear Equation in 2 variables?

An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

y = x - 4   be equation (1)

On simplifying the equation , we get

Adding 4 on both sides of the equation , we get

x = y + 4

Subtracting y on both sides of the equation , we get

x - y = 4

Therefore , the value of A is x - y = 4

Hence , the equation is x + ( -y ) = 4
