Answer:

5.6 ft

Step-by-step explanation:

sin a = 8/10

sin a = x/7

8/10 = x/7

x = 8/10 * 7 = 28/5 = 5.6 ft

Answer:

Option A

Step-by-step explanation:

If a football team gains 15 yards on a play, it will be recorded as '+ 15' or '15'.

All other options would be represented by '-15', and not '15' that is asked in the question. A withdraw is taking away money, a number 'below zero' would be negative, and losing 15 points would be represented as '-15'.

Option A should be the correct answer.

Answer:

The answer to your problem is Option A or 1: A football team gains 15 yards on a play.

Step-by-step explanation:

This is the answer because all of the other situations have an integer of -15. Like LOSING points, or 15 meters BELOW all signify that those situations include a negative number. Your question is asking for a positive 15 not negative so Option 1 is the correct answer.

Answer:

Step-by-step explanation:

Mary bought 1 fish, Ari bought 20 fish, Rodney bought 4 fish, Carissa bought 3 fish, Jacob bought 4 fish, Jack bought 1 fish, Jaleesa bought 2 fish, Andrea bought 5 fish, Geoff bought 1 fish, Becky bought 4 fish, Molly bought 1 fish, David bought 2 fish, Gina bought 7 fish, James bought 1 fish, Anessa bought 2 fish, Ted bought 1 fish, Sean bought 2 fish, Kerri bought 11 fish, Sammy bought 3 fish, Jameson bought 2 fish, Theresa bought 2 fish, Luz bought 2 fish, Tracy bought 4 fish, Jackson bought 5 fish, and Celia bought 7 fish.

Rewrite the numbers

1,20,4,3,4,1,2,5,1,4,1,2,7,1,2,1,2,11,3,2,2,2,4,5,7

1.

a: I can't draw a line plot, but I can tell you some tips.

Set the x as the different numbers that appear in the set

Set the y as the frequency of each number.

b: 2 fish has the highest frequency.

c: Add the terms. 97 is the total fish been bought

d: The outlier is 20 bought fish

2.

a: When making the stem and leaf plot, do it in this format

1| 7,4,3,5,8,4

and so on.

b: the heaviest puppy is 25 and the lightest is 13

so the range is 12

c: 4 puppies weighed at least 20 pounds

3. There are no following values, but for this I would make a box and whisker plot.

4. There is no histogram but it should be relatively easy if you know which aspect of the graph to use.

a: Find the frequency of each bar and add them.

b: the largest number of boxes is the interval that is the largest

c: Use the graph to find it

d: I can't do this without the graph.

Answer:

c

Step-by-step explanation:

(4 + 6i)(7-2i)=

28-8i+42i-12i^2

i^2=-1, so

28+12-8i+42i

40+34i

answer is c

Answer:

A=16

Step-by-step explanation:

A= 1/2*b*h

A=1/2*4*8

A=16

Answer:

Solve for area

A≈1134.11cm²

r Radius

19

cm

Solution

A=πr2=π·192≈1134.11495cm²

Answer: 1133.54

Step-by-step explanation:

The formula of area of a circle: A = [tex]\pi[/tex]r squared

All you have to do is plug the numbers in, so A= 3.14 (19) squared. Solve

19 times 19 = 361, and 3.14 times 361 = 1133.54

Answer:

b=16

Step-by-step explanation:

1) Divide 3 on both sides.

2) 3 divided by 3 and 48 divided 3.

3) Now you're left with 16, so the value of b is 16.

Answer:

1) Divide both sides by 3

2) b=16

Step-by-step explanation:

To solve the equation, we want to find out what b is. In order to do this, we have to get b by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.

3b=48

3 and b are being multiplied (3b=3*b). The opposite of multiplication is division. Therefore, divide both sides by 3.

3b/3=48/3

The 3s on the left will cancel, and we are left with:

b=48/3

b=16

Answer:

We have axis of symmetry in [tex]x=-1[/tex]

The vertex point is [tex](-1, -9)[/tex]

The roots by factoring are

[tex]x=-4[/tex]

[tex]x=2[/tex]

Step-by-step explanation:

We have the function:

[tex]f(x)=x^2+2x-8[/tex]

Factoring the quadratic equation:

[tex]y=(x+4)(x-2)[/tex]

When [tex]y=0[/tex]

[tex]0=(x+4)(x-2)[/tex]

[tex]x=-4[/tex]

[tex]x=2[/tex]

The vertex point is [tex](h, k)[/tex]

From the equation, we have [tex]a=1,\:b=2 \text{ and }\:c=-8[/tex]

[tex]$h=-\frac{b}{2a}$[/tex]

[tex]$h=-\frac{2}{2\cdot \:1}$[/tex]

[tex]h=-1[/tex]

We also got the axis of symmetry

In order to find [tex]k[/tex] just use the [tex]$h=x_{vetex}$[/tex]:

[tex]k=(-1)^2+2(-1)-8\\k=1-2-8\\k=-9[/tex]

Once [tex]a>0[/tex], we have the minimum at [tex](-1, -9)[/tex]

Answer:

x = -1  axis of symmetry

(-1,-9) vertex

x = -4           x=2   are the roots

Step-by-step explanation:

y = x^2 + 2x - 8

The axis of symmetry is

h = -b/2a

h = -2/ (2*1) = -2/2 =-1

x = -1

The x coordinate of the vertex is at the axis of symmetry

To find the y value substitute into the function

y = (-1)^2 +2(-1) -8

y = 1-2-8

y = -9

The vertex is at ( -1,-9)

Factor

What 2 number multiply to -8 and add to 2

4*-2 = -8

4+-2 = 2

y = ( x+4) (x-2)

Using the zero product property to find the roots

0 = ( x+4) (x-2)

x+4 =0    x-2 =0

x = -4           x=2   are the roots

Answer:

Question 7: Distributive

You multiple the outside element by each element inside the parenthesis

Question 5: 1.2x + 12.3y

2.4(3x + 2y) - 1.5(4x - 5y)  = 7.2x + 4.8y - 6x + 7.5y  = 1.2x + 12.3y

Question 3: 1 (3/5)x - (3/10)y

(2/5)(4x - 3y/4) = (8/5)x - 6y/20 = 1 (3/5)x - (3/10)y

Question 2: 1 (7/15)x

(4/5)x + (2/3)x = (12/15)x + (10/15)x = (22/15)x = 1 (7/15)x

Question 1: -2x + 3y

(3/4)(8x-4y) - (2/3)(12x - 9y) = 6x - 3y - 8x + 6y = -2x + 3y

Hope this helps!

Answer:

Question 7: Distributive

Question 5: [tex]1.2x+12.3y[/tex]

Question 3: [tex]$1\frac{3}{5}x -\frac{3}{10}y $[/tex]

Question 2: [tex]$1\frac{7}{15} x$[/tex]

Question 1: [tex]-2x+3y[/tex]

Step-by-step solution:

Question 7

[tex]4(x-5)=4x-20[/tex]

Distributive property, [tex]a(b + c) = ab + ac[/tex]. It says that multiplying the sum of two or more addends (numbers or terms added together) by a number (a) will give the same result as multiplying each addend individually. It is the same as the distributive property of multiplication over subtraction, except it will give the difference.

Question 5

[tex]2.4(3x + 2y) - 1.5(4x - 5y)[/tex]

Use the distributive property:

[tex]7.2x+4.8y-6x+7.5y[/tex]

[tex]1.2x+12.3y[/tex]

Question 3

[tex]$\frac{2}{5} \left(4x-\frac{3}{4}y \right)$[/tex]

Use the distributive property again:

[tex]$\frac{8}{5}x -\frac{6}{20}y $[/tex]

[tex]$\frac{8}{5}x -\frac{3}{10}y $[/tex]

Now you have to convert [tex]$\frac{8}{5} $[/tex] to mixed form:

It will give 1 with remainder 3, therefore

[tex]$\frac{8}{5} = 1\frac{3}{5} $[/tex]

[tex]$1\frac{3}{5}x -\frac{3}{10}y $[/tex]

Question 2

[tex]$\frac{4}{5} x +\frac{2}{3} x$[/tex]

[tex]$\frac{4(3)}{5(3)} x +\frac{2(5)}{3(5)} x$[/tex]

[tex]$\frac{12}{15} x +\frac{10}{15} x$[/tex]

[tex]$\frac{22}{15} x$[/tex]

Mixed form again:

[tex]$1\frac{7}{15} x$[/tex]

Question 1

[tex]$\frac{3}{4} (8x-4y) -\frac{2}{3} (12x - 9y)$[/tex]

[tex]$6x-3y -8x +6y$[/tex]

[tex]-2x+3y[/tex]

Answer:

number is 3 .equation below

Step-by-step explanation:

5(6+n)=n+42

30+5n=n+42

5n-n=42-30

4n=12

n=3

Answer:

List the factors of 12

1,12

2,6

3,4

That is the side lengths of the 3 rectangles

All the areas will be 12 because they are the factors 12

factors multiply to be a number

(length + width) x 2 = perimeter

1+12=13x2=26

1 by 12 has a perimeter of 26 and area of 12

2 by 6 has a perimeter of 16 and area of 12

3 by 4 has a perimeter of 14 and area of 12

Answer:

slope =2

y intercept = (0,-4)

Step-by-step explanation:

y = 2x - 4

Since this is in the form y = mx+b where m is the slope and b is the y intercept

The slope is 2 and the y intercept is -4

slope =2

y intercept = (0,-4)

Bottom Left: 124

Answer:

You will pay $18 for a item with original price of $90 when discounted 80%. In this example, if you buy an item at $90 with 80% discount, you will pay 90 - 72 = 18 dollars.

Step-by-step explanation:

Answer:

Original Price is $450

Step-by-step explanation:

(Discounted price) = (100 percent - discount percent) x (original price)

90 = (100%- 80%) x y

y = 90 / 0.20

= 450

Answer:

Cost, C = $28410.72

Step-by-step explanation:

We have, a concrete pillar has the shape of a cylinder.

Diameter of pillar is 8 m and ts height is 9 m

If concrete costs $87 per cubic meter, it is required to find the concrete cost for the pillar. For this lets find the area of cylindrical shape. So,

[tex]A=2\pi rh+2\pi r^2\\\\A=2\times 3.14\times 4\times 9+2\times 3.14\times 4^2\\\\A=326.56\ m^2[/tex]

The cost of pillar at the rate of $87 per cubic meter will be :

[tex]C=326.56\times 87\\\\C=\$28410.72[/tex]
