Answer:

B: 113

Step-by-step explanation:

I think you ment 113. a triangle has 180 degrees, the 2 angles add up to 67, subtracted from 180 = 113

Answer:418 and heres why

Step-by-step explanation:

2(14.5 times 7 = 101.5 times 2 = 203

next

2(14.5 times 5 =72.5 times 2=145

then last

2(7 times 5= 35 times 2=70  add them all together then get  418

hope this help (:

The surface area of the shoe box is,

⇒ SA = 418 square inches

We have to given that,

A shoe box has a length of 14.5 inches, a width of 7 inches, and a height of 5 inches.

Since, We know that,

Surface area of cuboid is,

SA = 2 (lw + lh + hw)

Here, we have;

Length = 14,5

Width = 7 inches

Height = 5 inches

Hence, We get;

The surface area of the shoe box is,

SA = 2 (14.5 x 7 + 14.5 x 5 + 5 x 7)

SA = 2 (101.5 + 72.5 + 35)

SA = 2 (209)

SA = 418 square inches

Thus, The surface area of the shoe box is,

⇒ SA = 418 square inches

Answer:

C

Step-by-step explanation:

So this one is pretty much like the last one

the distance on the x values is 6 and the distance on the y values is 4

1/6 of 6 is 1 and 1/6 of 4 is .66

We subtract the coordinates from R

4-1 is 3

2 -.66 =1.33

The 1/6 point is at (-3,1.33)

Answer:

#4,   x-1/(x^2+3x+2)

Step-by-step explanation:

x/(x^2+3x+2) - 1/((x+2)(x+1))

Convert the 1/((x+2)(x+1)) to 1/(x^2+3x+2)

now you have a common denominator to subtract

x/(x^2+3x+2) - 1/(x^2+3x+2)

results x-1/(x^2+3x+2)

Value of equation = 74

Step-by-step explanation:

Given:

-26x - y

And

x = -3

y = 4

Find:

Value of equation

Computation:

-26x - y

By putting value

-26(-3) - 4

78 - 4

74

Value of equation = 74

===================================================

Work Shown:

2x+3y = 18

3y = 18-2x ..... subtract 2x from both sides

3y = -2x+18

y = (-2x+18)/3 .... divide both sides by 3

y = (-2x)/3 + 18/3

y = (-2/3)x + 6

-----------

As a quick shortcut, anything in the form Ax+By = C will convert to y = (-A/B)x+(C/B) when you solve for y.

The slope is -A/B and the y intercept is C/B

Answer:

108000000x^2

Step-by-step explanation:

The given expression (2.4 × 10⁴) (4.5 × 10³) becomes 1.08 × 10⁸ after performing the operations.

To evaluate the expression (2.4 × 10⁴) (4.5 × 10³), we use the properties of exponents.

When multiplying numbers written in scientific notation, we multiply the coefficients and add the exponents.

(2.4 × 10⁴) (4.5 × 10³) = (2.4 × 4.5) × (10⁴ × 10³)

= 10.8 × 10⁷

Next, we simplify the result by adding the exponents since the base (10) is the same:

10.8 × 10⁷ = 1.08 × 10⁸

Therefore, the final result of the expression is 1.08 × 10⁸.

Answer:

6cm

Step-by-step explanation:

The formula for the surface area of a sphere = 4πr²

From the Question, we are given:

The surface area of a sphere = 144pi square centimeters = 144π cm²

The length of the radius of the sphere, in centimeters is calculated by:

4πr² = 144π

Divide both sides by 4π

4πr²/4π = 144π/4π

r² = 36

Square root both sides

√r² = √36

r = 6cm

Therefore, the length of the radius of the sphere, in centimeters is 6 centimeters.

If the corresponding side lengths of the two triangles are equal then the triangles are similar

Answer:

slope = - 2, point on line = (- 1, 3 )

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 3 = - 2(x + 1) ← is in point- slope form

with slope m = - 2 and (a, b ) = (- 1, 3 )

The slope of equation y−3=−2(x+1) is -2.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

y−3=−2(x+1)

Using Slope- Intercept form

y= mx + b

So, the slope for the equation is -2.

Hence, the slope is -2.
