Step-by-step explanation:

10x10=100

-10x-10=100

Answer:C

Answer: 1) h=5d+1.5

Step-by-step explanation:

Answer:

step 2 is the answer. when you start the question it's already in pemdas order. 48÷6 equals 8 then multiply it by the other 8 then you can add that quotient to the 10 which is 74 then subtract it by 7 and you get 67. step 2 goes the wrong way and ads the 8 with the 10 before multiplying the 8 by the 8 making everything go in wrong turns.

Answer:60 3/4

Step-by-step explanation:you multiply 81/4 times 3 and get 243/4 so you divide 243 divided by 4 and the answer is 60 3/4

Answer:

65

Step-by-step explanation:

f(x) = 2x² + 4

g(x) = x - 6

f(-5) = 2 * (-5)² + 4

= 50 + 4

= 54

g(-5) = - 5 - 6

= - 11

f(-5) - g(-5) = 54 + 11 = 65

Answer:

33.98

Step-by-step explanation:

To find the diameter of a circle when you have a circumference, all you need to do is divide the circumference by pi. (So 106.76 ÷ π)

So:

106.76 ÷ π = 33.98276344.... (irrational number)

I just cut off the rest of the numbers at the hundredth place for simplicity. Another way you could put it is:

[tex]\frac{106.76}{\pi }[/tex] which is basically saying 106.76 divided by pi.

Hope this helps and have a nice day!

Answer:

y = 1/4 x - 1/2

Step-by-step explanation:

Remark

The general equation for a line is y = mx + b

You know that m = 1/4. The problem is what do you do about (2,0)?

Solution

y = 1/4 x + b                  Let x = 2 when y = 0

0 = 1/4 * 2 + b               multiply 2 * 1/4

0 = 1/2 + b                     Subtract 1/2 from both sides

b = - 1/2

equation y = 1/4 x - 1/2

Answer:

C.) 78.5

Step-by-step explanation:

c = pi x r²

c = 3.14 x (5)²

c = 3.14 x 25

c = 78.54

c ≈ 78.5 (round to the nearest tenth) (4 is less that 5, so we round down to 5)

The orthocenter of a triangle is the point where the altitudes of the triangle intersect. The three altitudes of a triangle are always concurrent, meaning that they meet at the same point. As a quick reminder, the altitude is the line segment that is perpendicular a side and touches the corner opposite to the side.

Measure of ∠ABD = 42°

Correct option is d.

In trigonometry, there are six trigonometric ratios, namely, sine, cosine, tangent, secant, cosecant, and cotangent.

sin θ = Perpendicular/Hypotenuse

cos θ = Base/Hypotenuse

tan θ = Perpendicular/Base

sec θ = Hypotenuse/Base

cosec θ = Hypotenuse/Perpendicular

cot θ = Base/Perpendicular

Given in the figure,

ABC is right angle triangle

∠BAD = 90°

∠ABD = ?

AB = 125 ft

AD = 140 ft

tan ∠ABD = AB/AD

      ∠ABD = tan⁻¹ (125/128)

     ∠ABD = 41.76° ≈ 42°

Hence, 42° is the measure of ∠ABD.

The graph of the function is attached.

A curve that depicts an exponential function is known as an exponential graph. A curve with a horizontal asymptote and either an increasing slope or a decreasing slope called an exponential graph. i.e., it begins as a horizontal line, increases or drops gradually, and then the growth or decay accelerates.

Given the graph of function,

The graph of any exponential function is parallel to an  axis and drop and increase show the decay or growth,

since the  equation,

y = -2(3ˣ) + 5

has a negative sign the graph will go down,

y-intercept for the graph is 3,

when x = 0, y = 3

and the graph will be in the fourth quadrant.

Hence the graph will be in the fourth quadrant.

(OK)

The height (one of the legs) and the hypotenuse of an isosceles right triangle are 40 feet and 40√2 feet, respectively.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.

Given:

The triangle is an isosceles right triangle.

That means, the triangle has two equal sides.

Let, base b = height h.

The area of the triangle = 1/2 x base x height.

800 = (1/2)b²

b² = 1600

b = 40 feet.

Now, using the Pythagoras theorem,

Hypotenuse = √(1600 + 1600)

Hypotenuse = √(3200)

Hypotenuse = 40√2 feet.

Therefore, height = 40 feet and hypotenuse = 40√2 feet.

A number line with a closed dot at -4 is shaded to the right. Option A is correct.

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

Here,
Given inequality,
c – 12 ≥ –16

Add 12 on both sides
c ≥ -4

So the required number line would be as a closed dot at -4 and shaded to the right.

Thus, A number line with a closed dot at -4 is shaded to the right. Option A is correct.

Answer:

Helen

Step-by-step explanation:

Just did test

Both Felix and Sidney earned the same amount of commission, which is $39.15.

Helen earned the most commission, which is $45.00.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To calculate the commission earned by each salesperson, we need to multiply the rate of commission by the total sales amount.

The total sales amount is the product of the number of items sold and the cost of each item.

For Felix:

Commission = (Rate of commission) x (Total sales amount)

= 7.25% x (9 x $60)

= $39.15

For Helen:

Commission = (Rate of commission) x (Total sales amount)

= 7.50% x (12 x $50)

= $45.00

For Reid:

Commission = (Rate of commission) x (Total sales amount)

= 8.25% x (10 x $40)

= $33.00

For Sidney:

Commission = (Rate of commission) x (Total sales amount)

= 7.75% x (6 x $90)

= $39.15

Therefore,

Both Felix and Sidney earned the same amount of commission, which is $39.15.

Helen earned the most commission, which is $45.00.
