A 9-pack of popsicles costs $4.23. What is the unit price?

Answer:

z = 5

Step-by-step explanation:

divide both sides of the equation by -0.25

[tex]-0.25z = -1.25[/tex], original equation

[tex]\frac{-0.25z}{-0.25} =\frac{-1.25}{-0.25}[/tex], divide both sides by -0.25, solve for -1.25 ÷ -0.25 = 5

[tex]z = 5[/tex], final answer

Question 4

The error was that in step 2, when distributing -3 into the parentheses, the person did not change the sign of 24 so that it was negative, since a negative number multiplied by a positive number will always make a negative number. Here is the correct way to solve this equation:

[tex]-5x+12-7x=-3(5x+8)\\-12x+12=-3(5x+8)[/tex]

Distrubute -3 into the parentheses

[tex]-12x+12=-15x-24[/tex]

Subtract both sides by 12

[tex]-12x+12-12=-15x-24-12\\-12=-15x-36[/tex]

Add 15x to both sides

[tex]-12+15x=-15x-36+15x\\3x=-36[/tex]

Divide both sides by 3

[tex]\frac{3x}{3} =\frac{-36}{3} \\x=-12[/tex]

Question 5

The error was that 2 was added on both sides in step 5 instead of being subtracted from both sides. Here is the correct way to do it, starting from step 4:

[tex]10=16x+2[/tex]

Subtract both sides by 2

[tex]10-2=16x+2-2\\8=16x[/tex]

Divide both sides by 16

[tex]\frac{8}{16} =\frac{16x}{16} \\\frac{1}{2}=x[/tex]

I hope this helps!

Answer:

D

Step-by-step explanation:

Answer: D

The first option is incorrect because 56+angle 3=180 and when you solve it angle 3 equals 124 degrees, not 142 degrees

The second option is incorrect because 56+43+angle 1=180 (because all triangles add up to 180 degrees). When you solve that angle 1 equals 81 degrees, not 99 degrees

The third option is incorrect because angle 1+angle 2=180, and we already know angle 1 equals 81, so when you solve that angle 2 equals 99 degrees, not 137 degrees. So we know the last option is correct.

But if you want to make sure it's correct, you can always solve for angle 4. Angle 4+43=180 degrees, and when you solve it, angle 4 equals 137 degrees, and we know that option is correct.

Hope this helped you!

Answer:

The ratio of red to blue would be 60: 6 which can be simplified to 10:1.

The ratio of red to blue counters would be 60: 6 which can be simplified to 10:1

Ratio is the comparison of two quantities in terms of same units.

Example : If a & b be two numbers, then the ratio is a/b, where b≠0

Let Blue counters = x

Red counters would be = 3 times of blue counters = 3x

There are a total of 120 counters in a box.

First we have to find, the number of red and the number of blue counters:

3x + x = 120

⇒ 4x = 120

⇒ x = 120/4

⇒ x = 30

There are 30 blue counters.

Red counters = 3×30 = 90

Carl took 1/3 of the red, 90 / 3 = 30, so there were 60 red counters left in the box.

Kerry took 80% of the blue, 30 * 0.80 = 24, so there were 6 blue counters left in the box.

The ratio of red to blue counters would be 60: 6 which can be simplified to 10:1.

Answer:

37.17

Step-by-step explanation:

Find the mean by adding together all of the numbers, then dividing it by how many numbers there are.

(29 + 75 + 21 + 45 + 39 + 14) / 6

= 37.17

So, if 29 is added, the mean is approximately 37.17

well in a brief explanation you need at least two (2) recessive (y) to make one red plant which there is not any so the two dominant plant will come out successfully as a dominant (Y) and there will also be yellow leaves with the one recessive

Here, the yellow leaves are dominant and red leaves are recessive. Then, if they have four offspring, they will not have offspring with red leaves. Hence, option A , zero is correct.

In genetics, a dominant genotype is a genetic trait that is expressed when an individual has one or two copies of the dominant allele.

Here, since yellow leaves (Y) are dominant over red leaves (v), a plant with the genotype Yy will have yellow leaves.

When a plant with the genotype Yy (one dominant Y allele and one recessive v allele) is crossed with a plant with the genotype YY (two dominant Y alleles), the possible gametes from each parent are:

Yy plant: Y gamete or v gamete

YY plant: Y gamete

The possible offspring genotypes and their corresponding phenotypes can be determined using a Punnett square

 | Y | Y

Y | YY| YY

y | Yy| Yy

As shown in the Punnett square, all of the offspring will have the genotype Yy and therefore have yellow leaves. None of the offspring will have the genotype vv required to produce red leaves.

Therefore, the answer is 0 (none of the offspring would have red leaves), Hence, option A is correct.

The solution is, the area of the following figure is 360 in^2.

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

For this case we have that by definition, the area of a rectangle is given by:

A = l*w

In this case, the rectangle is 18 in side, & 21 in.

then:

A = 18*21

   = 378

On the other hand, the area of a triangle is given by:

A = 1/2 b * h

Where:

b: It is the base of the triangle

h: It is the height

We have according to the figure that:

b = 21 - 17 = 4

h = 18 - 9 = 9

So:

A = 1/2 *4 *9

   =18

Finally, the area of the figure is:

378 - 18

=360

Answer: The solution is, the area of the following figure is 360 in^2.

Answer:

Step-by-step explanation:

The domain, the possible values of x, is only limited in this function when the function is undefined. Specifically division by zero is undefined. In this case x cannot be equal to 9 because that would lead to division by zero. And that is the only restriction. So the domain is all real numbers except 9. In interval notation this is

x=(-oo, 9),(9, +oo)
