Answer:

16,21,15

Step-by-step explanation:

The solutions are 16, 21, and 15. The only value that is not a solution is 11 since 11 is less than 15

Inequality expressions are expressions separated by an unequal sign

Given the inequality expression 15 ≤ y

On swapping sides, the inequality sign will change to have y ≥ 15

Based on the table, we need to select yes for values that are greater than or equal to 15 and select no if otherwise

Based on the given value, the solutions are 16, 21, and 15. The only value that is not a solution is 11 since 11 is less than 15

each shirt costs $25

Step-by-step explanation:

we can make an equation using x as the cost of each shirt. since 254 was the total, they will=254 together , and since we have 9 shirts, its 9x. we can use this info to create the equation 9x+29=254. we subtract 29 on each side to get 9x=225. we then divide 9 on both sides to get x=25. so each shirt costs $25

Answer:

because they help us better analyze data

Step-by-step explanation:

we can see a lot of data on one small thing such as a graph, so we can easily graph data from many years on one graph

Graphs in mathematics help us visually represent equations and display data, allowing us to understand patterns, trends, and relationships between variables.

Graphs are an important tool in mathematics as they help us better understand our world by visually representing equations and displaying data. Graphs can show the relationship between different variables, such as in a line graph where one variable is plotted on the horizontal axis and another on the vertical axis. They can also represent data using bar graphs or pie graphs, which help us compare and interpret numerical information.

For example, if we want to analyze the temperature changes throughout a year, we can plot the temperature on the vertical axis and the months on the horizontal axis. By connecting the data points, we can see patterns and trends, such as variations in temperature during different seasons.

In addition, graphs allow us to make predictions and draw conclusions based on the data presented. By analyzing the shape and slope of a graph, we can determine the rate of change, identify maximum and minimum values, and make predictions about future outcomes.

Step-by-step explanation:

answer: v = -13

step by step explanation:

Answer:

v = - 13

Step-by-step explanation:

Distribute parenthesis on both sides of the equation

54 - 18v = - 12v + 132 ( add 12v to both sides )

54 - 6v = 132 ( subtract 54 from both sides )

- 6v = 78 ( divide both sides by - 6 )

v = - 13

Answer:

To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.

this will show u i searched it and wrote half in my words

Answer:

315 in^2

Step-by-step explanation:

Triangles

Area of the two triangular faces.

Area = 1/2 * h * b

h = 7 in

b = 11 in

Area = 1/2 * 7 * 11

Area = 1/2 * 77

Area = 38.5

But there are 2 faces

Area = 38.5 * 2

Area = 77 in^2

Area Left Face

Area left face = height * width

Area left face = 14 * 8

Area left face = 112 in^2

Area Right face

Area Right face = w*h

w = 9

h = 14

Area = w*h

Area right face = 126 in^2

Total Area

Total Area = 126 + 112 + 77

Total Area = 315 in^2

Answer: OPTION C

Step-by-step explanation:

Use the following formula:

[tex]SA=\frac{pl}{2}+B[/tex]

Where p is the perimeter of the base, l is the slant height and B is the area of the base.

The perimeter is:

[tex]p=4*s=4*5.3yd=21.2yd[/tex]

Where s is the side lenght

The slant height is given:

[tex]l=11.1yd[/tex]

The area of the base is:

[tex]B=s^2=(5.3yd)^2=28.09yd^2[/tex]

Where s is the side lenght

Substitute values. Then, the result is:

[tex]SA=\frac{(21.2yd)(11.1yd)}{2}+28.09yd^2)=145.75yd^2[/tex]

Answer:

The correct answer option is C. 145.75 yd^2.

Step-by-step explanation:

We are given a diagram of a right square pyramid with a slant height 11.1 yd, and base edge length 5.3 yd.

We know that the surface area of a right square pyramid is given by:

[tex]\frac{PI}{2} +B[/tex]

where P = perimeter of the base, I = slant height and B = base area.

Perimeter of base = [tex]4 \times 5.3[/tex] = 21.2 yd^2

Base Area = [tex]5.3^3[/tex] = 28.09 yd^2

Surface area of right square pyramid = [tex]\frac{21.2 \times 11.1 }{2} + 28.09[/tex] = 145.75 yd^2

Leo earned approximately $992.08 in interest after 13 years.

Compound interest is calculated using the formula:

A = P(1 + r/n)^(nt)

Where:

In this case, Leo deposited $2494.05 with an interest rate of 2.5% compounded weekly for 13 years. Plugging the values into the formula:

A = 2494.05(1 + 0.025/52)^(52*13)

A = 2494.05(1.00048077)^(676)

A ≈ $3486.13

To find the interest earned, subtract the principal amount from the total future amount:

Interest = A - P

Interest ≈ $3486.13 - $2494.05

Interest ≈ $992.08

Answer:

A. 3 Inches

Step-by-step explanation:

To find the radius of the circle, we need to use the Pythagorean Theorem.

a²+b²=c²

a = r inches

b = AD or 4 inches

Now to get the value of c, we need to consider the measurement of the line AD. The sum of line AD and line DC will be the value of the hypotenuse.

c = r + 2 inches

Now that we have our variables, let's plug them in.

a² + b² = c²

r²+ 4² = (r + 2)²

Now we need to use the FOIL method for r + 2.

r² + 16 = (r + 2)(r + 2)

r² + 16= r² + 2r + 2r + 4

r² + 16 = r² + 4r + 4

Now we can remove r² by subtracting both sides by r², leaving us with:

16 = 4r + 4

Now we subtract 4 from both sides.

4r = 12

Now we divide both sides by 4.

r = 3 inches

Answer:

A. 3 inches

Step-by-step explanation:

Triangle ABC is a right angled triangle

Therefore;

Using the Pythagoras theorem then;

AB² + BC² = AC²

but BC = CD = radius

Hence;

4² + r² = (r+2)²

16 + r² = r² + 4r +4

 16 - 4 = 4r

    12 = 4r

   r = 3

Therefore; the radius of the circle is 3 inches

Answer:

She can chose 2 books from 8 books in 28 different way.

Step-by-step explanation:

In the given scenario the member has to chose 2 books from a group of 8 books. The order of choosing books does not matter. For example if the books are A,B,C,D,E,F,G and H, and the member picks books A and B or books B and A, she is picking up the same books. This means order of selection does not matter here, so this is a problem of combinations.

We have to form combination of 8 books taken 2 at a time i.e. 8C2

The general formula of combination is:

[tex]nCr=\frac{n!}{r!(n-r)!}[/tex]

Using the values of n=8 and r=2, we get:

[tex]8C2=\frac{8!}{2!(8-2)!}=28[/tex]

This means, she can chose 2 books from 8 books in 28 different ways.

This is an isosceles triangle because it has two sides with lengths, hence the angles opposite the equal sides are also equal, that is ∠U = ∠V.

So we can say that:

∠U = ∠V = α

∠W = β

Since the internal angles of a triangle add up to 180 degrees, then:

α + α + β = 180

2α + β = 180

β = 180 - 2α

Using the law of sine:

[tex]\frac{35}{sin\beta} =\frac{30}{sin\alpha} \\ \\ \frac{35}{sin(180 - 2\alpha)} =\frac{30}{sin\alpha} \\ \\ \\ From \ Properties: \\ \\ sin(180-2\alpha)=sin(180)cos2\alpha-sin2\alpha cos(180) \\ \\ = -sin2\alpha(-1)=sin2\alpha \\ \\ Also: \\ \\ sin2\alpha=2sin\alpha cos\alpha[/tex]

Therefore:

[tex]\frac{35}{2sin\alpha cos\alpha} =\frac{30}{sin\alpha} \\ \\ \therefore \frac{35}{60}=cos\alpha \\ \\ \alpha=cos^{-1}(\frac{7}{12})=54.31^{\circ}[/tex]

But we want to know ∠W = β, therefore:

[tex]\beta = 180 - 2\alpha \\ \\ \beta =180-2(54.31)=71.37^{\circ}[/tex]

And rounded to the nearest degree:

∠W = 71°
