can somebody help with this??????

Answers

Answer:

Step-by-step explanation:

The equation can be made more clear by changing the form.

g(h(0)) = ?

All we have to do is find the y values for an x value of 0

h(x) = x^2 - 3

h(0) = 0^2 - 3

h(0) = -3

So now we plug in -3 for g(x)

g(x) = -2x

g(-3) = -2(-3)

g(-3) = 6

A bakery sells chocolate cupcakes and mocha cupcakes. One day it sold 153 chocolate
and 187 mocha. What percent of the cupcakes sold that day were chocolate?

Answers

Answer:

45% of the cupcakes baked on that day were chocolate flavored.

Step-by-step explanation:

Hey there!

We're given that the bakery sold 153 chocolate cupcakes and 187 mocha cupcakes.

Let's find the total number of cupcakes baked in a day.

[tex]153 + 187 = 340[/tex]

Now, we need to find the ratios of the cupcakes. Of the 340 cupcakes baked, 153 were chocolate flavored. Therefore, we can create a ratio between the two values and find the percentage.

Step 1: Define Values

153 chocolate cupcakes baked340 cupcakes in total

Step 2: Create Ratio and Simplify

[tex]\displaystyle \frac{\text{153 chocolate cupcakes}}{\text{340 total cupcakes}} = \frac{153}{340} = 0.45[/tex]

Step 3: Convert from Decimal Form to Percentage Form

[tex]0.45 \times 100\% = 45\%[/tex]

Therefore, we have determined that 45% of the cupcakes baked on that day were chocolate flavored.

The area of a rectangle is 560 square inches. The length is 3 more twice the width. Find the length and width.

Answers

Answer:

l = 35 inches and b = 16 inches

Step-by-step explanation:

Let length be b and width be b.

The area of a rectangle is 560 square inches.

Length is 3 more twice the width.

l = 2b+3 ....(1)

We know that,

Area = length × width

560 = (2b+3)b

[tex]2b^2+3b-560=0\\\\b=16,-17.5[/tex]

Put b = 16 in equation (1).

l = 2(16)+3

= 35 inches

So, the length is 35 inches and the width is 16 inches.
