Answers

Answer:

p = 1

Step-by-step explanation:

4 - 5(p + 3/5) = -4

Find P

4 - 5(p + 3/5) = -4

4 - 5p -15/5 = -4

4 - 5p - 3 = -4

-5p + 1 = -4

-5p = -4 - 1

-5p = -5

p = -5/-5

p = 1

Check:

4 - 5(p + 3/5) = -4

4 - 5(1 + 3/5) = -4

4 - 5 - 15/5 = -4

4 - 5 - 3 = -4

4 - 8 = -4

The linear equation c = 6.5n + 1500 models cost c, in dollars, to produce n toys at a toy factory. What is the y-intercept, and what does it mean in this context?

A)The y-intercept is 6.5 and represents the number of toys produced increases by about 6.5 for each $1 increase in cost.
B)
The y-intercept is 1500 and represents the costs $1500 to run the factory if no toys are produced.
C)The y-intercept is 1500 and represents The factory can produce 1500 toys at no cost.
D)The y-intercept is 6.5 and represents the cost increases by $6.50 for each toy produced.

Answers

Answer:

B

Step-by-step explanation:

This is because 6.5n is the slope and the +1500 is the y-intercept. Remember its y=mx+b.

Answer:

gsjxvsHGVSHGCZJ

Step-by-step explanation:

like you did to me

Answer:

x = -7

Step-by-step explanation:

The interior angles of a triangle should all add up to 180 degrees.

So, we set the equation up as:

(x + 52) + 75 + 60 = 180

Then solve for x:

(x + 52) + 75 + 60 = 180

(x + 52) + 135 = 180

x + 52 = 180 - 135

x = 45 - 52

x = -7

you will get 12 and multiply by 10

C. 120

or a faster way to solve these is just 150 (total # of students) and multiply by the percent in decimal form which in this case would be 0.80 (because percentage is out of 100, 80% is 80/100, which is 0.80 as a decimal)

The possible outlier may be [tex](0,1)[/tex] as the second component is not greater than second components of the remaining pairs in comparison.

How to determine the possible outlier

In this data set, we observe that data set observes the rule that first component increases inasmuch the second component of the ordered pairs decreases.

Write the equation of a circle with center (0,−6) and radius 4 in general form.


Answers

Answer:

x^2 + (y + 6)^2 = 4^2

Step-by-step explanation:

The general form we need here is (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center and r is the radius.

If the center is at (0, -6) and the radius is 4, then the desired equation is

(x - 0)^2 + (y + 6)^2 = 4^2, or just

x^2 + (y + 6)^2 = 4^2

Two sides of a right triangle measure 222 units and 444 units. What is the area of the square that shares a side with the third side of the triangle?

Answers

Answer:

the area of the square = x² = 147,852 ft²

Step-by-step explanation:

Given;

two sides of a right triangle, = 222 units and 444 units

let the third side of the right triangle that shares a side with a square = x

the third side is obtained by applying Pythagoras theorem, and assuming the third side to be either adjacent or opposite side.

x² = 444² - 222²

x² = 147,852

x = √147,852

x = 384.52 ft

Therefore, the area of the square = x² = 147,852 ft²

Answer:

20 = x^2

Step-by-step explanation:

to find c^2 you need to do:

a^2 + b^2 = c^2

so- 2x2 + 4x4 = 4+16= 20

20 = x^2 and since x is squared you do not find the square root

A line passes through the points (0, 3) and (10, 2). What is its equation in slope-intercept form?

Answers

Answer:

1. Find slope.

slope(m)

[tex] = \frac{y2 - y1}{x2 - x1} \\ [/tex]

[tex] \frac{2 - 3}{10 - 0} = \frac{ - 1}{10} [/tex]

2. Substitute any point. (either (0,3) or (10,2) to find the y-intercept (b)

y=mx+b

3=-1/10+b

b=31/10 or 3.1

so the final answer is

y= - 1/10 + 31/10 or y= - 0.1 + 3.1

The surface area of the cone is 56.52 in².

What is Surface Area?

An object's surface area is the total area that all of its surfaces occupy. Many 3D shapes in geometry have various surface areas, which are simply calculable using the formulas.

As per the given diagram:

slant height of the cone (l) = 7 inch

radius of the cone (r) = 2 inch

For the surface area of the cone:

= πr(l+r)

= (22/7) × 2 × (7 + 2)

= (396/7)

= 56.52 in²

Hence, the surface area of the cone is 56.52 in²

Solve the equation 5(x+6)+11=25−3x

Answers

Answer:

x=-2

Step-by-step explanation:

Let's solve your equation step-by-step.

5(x+6)+11=25−3x

Step 1: Simplify both sides of the equation.

5(x+6)+11=25−3x

(5)(x)+(5)(6)+11=25+−3x(Distribute)

5x+30+11=25+−3x

(5x)+(30+11)=−3x+25(Combine Like Terms)

5x+41=−3x+25

5x+41=−3x+25

Step 2: Add 3x to both sides.

5x+41+3x=−3x+25+3x

8x+41=25

Step 3: Subtract 41 from both sides.

8x+41−41=25−41

8x=−16

Step 4: Divide both sides by 8.

8x

8
