Varvara68 [4.7K]3 years ago
8 0

Answer:

Ed would earn $4480

Step-by-step explanation:

you could solve this by ratios

make x = the amount of money he would earn if he worked 40 hrs

step 1: write the ratio

112/8 = x /40

step 2: cross multiply

8x = 4480

step 3: isolate x by dividing

8x/8 = 4480/8

answer: x = 560

Is x = 5 a solution to 47 = 6x
vladimir1956 [14]

Answer: No

Explanation:<em> </em>Here, we want to decide if 5 is a solution

for the equation 47 = 6x.

We can do this by simply plugging in 5 for <em>x</em>. If the statement holds true when 5 is plugged in for <em>x</em>, then 5 is a solution.

Plugging in 5 for <em>x</em> we have 47 = 6 (5).

6 (5) is equal to 30 so we have 47 = 30.

Since 47 and 30 are not equal, the statement 47 = 30 is not true.

Since 47 ≠ 30, this is a false statement which means 5 is not a solution for the equation 47 = 6x.

The length of each side of an equilateral triangle is increased by 20%, resulting in triangle ABC. If the length of each side of
kompoz [17]

Answer: Area of ΔABC is 2.25x the area of ΔDEF.

Step-by-step explanation: Because equilateral triangle has 3 equal sides, area is calculated as

A=\frac{\sqrt{3} }{4} a^{2}

with a as side of the triangle.

Triangle ABC is 20% bigger than the original, which means its side (a₁) measures, compared to the original:

a₁ = 1.2a

Then, its area is

A_{1}=\frac{\sqrt{3} }{4}(1.2a)^{2}

A_{1}=\frac{\sqrt{3} }{4}1.44a^{2}

Triangle DEF is 20% smaller than the original, which means its side is:

a₂ = 0.8a

So, area is

A_{2}=\frac{\sqrt{3} }{4} (0.8a)^{2}

A_{2}=\frac{\sqrt{3} }{4} 0.64a^{2}

Now, comparing areas:

\frac{A_{1}}{A_{2}}= (\frac{\sqrt{3}.1.44a^{2} }{4})(\frac{4}{\sqrt{3}.0.64a^{2} } )

\frac{A_{1}}{A_{2}} = 2.25

<u>The area of ΔABC is </u><u>2.25x</u><u> greater than the area of ΔDEF.</u>

Confused on what its asking PLEASE HELP
eduard

For question 6, recall that a sinusoidal function is of the form

A*sin(ω*t + φ)

where A is the amplitude, ω the angular frequency (in units of radians/second), and φ the phase (in radians). The amplitude is the magnitude of the peaks and troughs, the angular frequency inversely proportional to the period (ω = 2*π/T - the 2*π being a normalizing factor), and the phase a value between 0 and 2*π that "shifts" the graph of the function accordingly.

For question 7, you are being asked to find the composite function obtained by applying g to f, which would be  1/\sqrt{3-t} . The domain would be the values for which this function is defined, which, assuming it to be a subset of the real numbers, would be the interval (-∞, 3] (as the square root of a negative number is an imaginary number.
