A boy starts from a point A and walks 4 km due east to B. He then changes direction and walks 3 km due north to C. Find the distance of C from A.​

Answers

Answer 1

Answer:

Distance C from A =5km

Step-by-step explanation:

use the Pythagoras theorem's

{AC}^{2} = {BC}^{2} + {AB}^{2}

AC=✓3^2 + 4^2

AC = ✓9+16

AC = ✓25

AC = 5 km

therefore, C from A = 5 km

is this table a function?

Answers

Answer: No, it is not a function

We have x = 81 repeat itself. Any time x repeats, it means we don't have a function.

Put another way, the input x = 81 leads to more than one y output. A function is only possible if any given input leads to exactly one output. The input must be in the domain.

No
You can’t have two different numbers on the same x point. 81 is not able to be a negative 9 and a positive in the same graph

Answers

Answer:

C

Step-by-step explanation:

The guy who has 7.5k answers said so. Plus I need the 50 B Points

The equation that best models the relationship between the amount of compost used and the harvest yield is y = x+200

What is an equation?

Mathematically, an equation can be defined as a statement that supports the equality of two expressions, which are connected by the equals sign “=”.

Given that, a graph that shows the harvest results of a farm, we need to construct an equation that will give a relation between the compost used and the yield,

So the coordinates are

(0,200)

(200,400)

(400,600)

(600,800)

Finding the slope,

600-400 / 400-200 = 200/200 = 1

The y-intercept is 200, so, the relationship is

y=200+x

Hence, the equation that best models the relationship between the amount of compost used and the harvest yield is y = x+200

Pam Everett earned gross wages of $378. Pam's deductions were: $28 in federal withholding taxes, 6.2% in Social Security taxes, 1.45% in Medicare taxes, $20.4 in health insurance, and $28 in union dues. Find the total deductions from Pam's gross pay.

Answers

Answer:

Total deductions = $105.317

Step-by-step explanation:

Gross earning = $378

Deductions:

Federal withholding tax = $28

Social security tax = 6.2% of $378 = $23.436

Medicare tax = 1.45% of $378 = $5.481

Health insurance = $28

Total deductions is gotten by summing up all values above

28+23.436+5.481+20.4+28

= $105.317

The difference between gross earning and deductions

= 378-105.317

= $272.683

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

On farmer Palmer’s farm, the cats have got into the chicken coop and are causing chaos. Farmer Palmer counts in total, 11 heads and 30 legs.

We know that a goat has four legs and a chicken has 2 legs.

Let 'x' be the number of chickens and 'y' be the number of goats. Then the equations are given as,

x + y = 11                  ...1

2x + 4y = 30           ...2

From equations 1 and 2, then we have

2(11 - y) + 4y = 30

22 - 2y + 4y = 30

2y = 8

y = 4

Then the value of 'x' is given as,

x = 11 - 4

x = 7

The number of chickens and goats will be 7 and 4, respectively.

Answer:

Step-by-step explanation:

The equation of a circle centred at the origin is

x² + y² = r² ( where r is the radius )

x² + y² = 49 ← is in this form with

r² = 49 ( take square root of both sides )

r = [tex]\sqrt{49}[/tex] = 7

Thus A = (7, 0 ) and B = (0, 7 )

To find M use the midpoint formula

M = ( [tex]\frac{7+0}{2}[/tex], [tex]\frac{0+7}{2}[/tex] ) = (3.5, 3.5 )

The equation of a line passing through the origin is

y = mx ( m is the slope )

Calculate m using the slope formula

m = [tex]\frac{x_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (3.5, 3.5 )

m = [tex]\frac{3.5-0}{3.5-0}[/tex] = [tex]\frac{3.5}{3.5}[/tex] = 1

y = x ← equation of line passing through O and M

Answer:

Below in bold.

Step-by-step explanation:

(a)

At point A,  y = 0 so the coordinates of A are found as follows:

x^2+ 0^2 = 49

x^2 = 49

x = 7   so A is (7, 0).

In a similar way,  by putting x = 0 in the equation, we can show that

B = (0, 7).

(b)

M is the midpoint of the line AB so its coordinates are:

(7+ 0)/2, (0 + 7) /2 = (3.5, 3.5).

So the slope of OM  which also passes through the origin (0,0) is:

(3.5 - 0) /(3.5 - 0) = 1.

y - y1 = m (x - x1)

y - 3.5 = 1(x - 3.5)

y = x - 3.5 + 3.5

y = x is the required equation.

Noah can't wait for lunchtime. Today is taco day! The cafeteria made three times as many beef tacos as chicken tacos and 50 more fish tacos as chicken tacos. They made 945 tacos in all. How many more beef tacos are there than fish tacos? Correct answer with units (if applicable) is worth 2 points; correct answer only is worth 1 point.

Answers

Answer:

308 beef tacos

Step-by-step explanation:

Let chicken tacos = c

Let beef tacos = 3c

Let fish tacos = c + 50

945 = c + 3c + c + 50

Simplify to 945 = 5c + 50

Subtract 50 on both sides and divide 5 to get

chicken tacos = 179

Plug in 179 to beef tacos to get 179*3 = 537

Plug in 179 to fish tacos to get 179 + 50 = 229

Subtract 537-229 to get how many more beef tacos than fish tacos, and so the answer is 308 beef tacos
