Answer: She should sell each T-Shirt for at least $4.41

Step-by-step explanation:

First you need to figure out what the total cost of the 200 t shirts was plus shipping. so 200 t shirts for 2.8 would cost $560 + a 5% shipping fee ($28) = 588 if she wants to markup by 150. you would then multiply 588 * 1.5 = $882. This would be the final money she wants to make by the end of her school carnival. Divide 882/200 (amnt of t-shirts) to get $4.41 per shirt

Given:

Two numbers are 32 and 28.

To find:

The GCF of 32 and 28 and using the GCF find the factor of (32-28).

Solution:

(a)

Two numbers are 32 and 28. The factor form of given numbers are:

[tex]32=2\times 2\times 2\times 2\times 2[/tex]  

[tex]28=2\times 2\times 7[/tex]

Clearly, 2 and 2 are common factors in both.

[tex]GCF(32,28)=2\times 2[/tex]

[tex]GCF(32,28)=4[/tex]

Therefore, the GCF of 32 and 28 is 4.

(b)

Using the GCF we need to find the factor of (32-28).

[tex]32-28=4\times 8-4\times 7[/tex]

Taking out the GCF, we get

[tex]32-28=4\times (8-7)[/tex]

Therefore, [tex]32-28=4\times (8-7)[/tex].

Answer:

c = 29

Step-by-step explanation

heeyyyy I know this question was posted a long time ago, but uhhhhhh I felt like answering anyways sooooooo

Ok, so since the angle across from b is 97˚, that means b is 97˚ as well.

So then we have 54 + 97 + c = 180

151 + c = 180

c = 29

In the provided sequence there are four terms after expanding the sequence and the sequence is  0 + 3 + 8 + 15.

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

It is given that:

3

Σ n(n + 2)

n = 0

After expanding the above sequence:

= 0(0 + 2) + 1(1 + 2) + 2(2 + 2) + 3(3 + 2)

= 0 + 3 + 2(4) + 3(5)

= 0 + 3 + 8 + 15

As we can see in the above sequence there are four terms.

Divergent sequences are those in which the terms never stabilize; instead, they constantly increase or decrease as n approaches infinity, approaching either infinity or -infinity.

Thus, in the provided sequence there are four terms after expanding the sequence and the sequence is 0 + 3 + 8 + 15.

Answer:

Area of the triangle = 12.92 cm²

Step-by-step explanation:

Area of a triangle = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

From the figure attached,

Length of base of the triangle = 7.6 cm

Length of the height of the triangle = 3.4 cm

Area of the triangle = [tex]\frac{1}{2}(7.6)(3.4)[/tex]

                                 = 12.92 square cm

Answer:

125 meters

Step-by-step explanation:

Let distance = d and time is t

Using the variation;

d = k t^2

So let’s us get k

80 = k * 4*2

16k = 80

k = 80/16 = 5

So for 5 seconds, the distance would be;

d = 5 * 5^2

d = 125 meters

Answer:

$43,264

Step-by-step explanation:

Given :

% Commission earned per week = 13%

Worth of stock sold last week = 6400

If same amount is averaged each week during 2011 ;

Number of weeks per year = 52

Worth of stock for the year = (6400 * 52) = $332,800

Average Commission for the year = 13% of 332,800

0.13 * 332,800

= $43,264

The required value of x in the JKLM parallelogram is 21. Option C is correct.

Given that,
For a parallelogram, JKLM, the value of x is to be determined.

A parallelogram is a quadrilateral consisting of pairs of parallel sides.

Here,
For the parallelogram, the sum of the adjacent angle is 180°. So,
3x + 20 + 5x - 8 = 180
8x = 180 - 12
x = 168 / 8
x = 21

Thus, the required value of x in the JKLM parallelogram is 21. Option C is correct.

In mathematics, proportions refer to the equality of two ratios. A ratio is a comparison of two quantities, typically expressed as a fraction. When two ratios are equal to each other, they form a proportion.

A proportion can be written in the form:

a/b = c/d

Here, "a" and "b" are the terms of the first ratio, and "c" and "d" are the terms of the second ratio. The proportions state that the ratio of "a" to "b" is equal to the ratio of "c" to "d".

Step-by-step explanation:

Answer:

1) Velocity

[tex]v(t) = -4\cdot t^{3}+36\cdot t^{2}[/tex]

Acceleration

[tex]a(t) = -12\cdot t^{2}+72\cdot t[/tex]

2) Velocity

[tex]v(t) = -4\cdot t^{3}+24\cdot t^{2}[/tex]

Acceleration

[tex]a(t) = -12\cdot t^{2}+48\cdot t[/tex]

Step-by-step explanation:

From Physics we remember that velocity ([tex]v(t)[/tex]) and acceleration ([tex]a(t)[/tex]) are the first and second derivatives of the function position in time. That is:

1) Let [tex]s(t) = -t^{4}+12\cdot t^{3}[/tex], where [tex]t \ge 0[/tex]. The functions velocity and aceleration are, respectively:

Velocity

[tex]v(t) = -4\cdot t^{3}+36\cdot t^{2}[/tex]

Acceleration

[tex]a(t) = -12\cdot t^{2}+72\cdot t[/tex]

2) Let [tex]s(t) = -t^{4}+8\cdot t^{3}[/tex], where [tex]t\ge 0[/tex]. The functions velocity and acceleration are, respectively:

Velocity

[tex]v(t) = -4\cdot t^{3}+24\cdot t^{2}[/tex]

Acceleration

[tex]a(t) = -12\cdot t^{2}+48\cdot t[/tex]
