Answer:

the total cost of the brackets before tax is $89.7

Step-by-step explanation:

The computation of the total cost of the bracket before tax is as follows

Given that

height = 9 feet

length = 10 feet

wall brackets:

48-in costing $12.95

60-in costing $16.95

The distance of brackets from ends is 1 foot

The maximum distance between brackets is 24 inches

Now based on the above information

The brackets are

= 48 ÷ 12

= 4 feet

And

= 60 ÷ 12

= 5 feet

The length of the shelf is  60 inch

Now the 1 could be deducted from each side

= 60 - 2

= 58 in

Now Divide it by 24 inches

= 58 ÷ 24

= 2.41 ~ 3  

Finally, The total cost is

= ($12.95 + $16.95) × 3

= $89.7

Hence, the total cost of the brackets before tax is $89.7

Answer:

-2

Step-by-step explanation:

f(t) = t^2 – 2t – 2

To find f(0), replace t with 0 in the expression and evaluate the expression.

f(0) = 0^2 – 2(0) – 2

f(0) = -2

0 = t

We know this because 0 replaced t in the parenthesis next to F !

The question is just asking you to plug in 0 where ever t is!

Let's do it

[tex]f(0) = 0^{2} - 2(0) - 2[/tex]

solve

[tex]0^{2} = 0 \\2 ( 0 ) = 0[/tex]

so, this is what we have left!

[tex]f(0) = 0 - 0 - 2[/tex]

We have our answer!

[tex]f (0) = -2[/tex]

Answer: B, $4.41 per shirt

Step-by-step explanation:

To figure this out you want to first take the 200 shirts and multiply them by the cost of $2.80. This gives you a total of $560, without tax. The tax is 5%, so you want to take 560 and multiply it by .05 to find the amount of tax. This leaves you with $28 of taxes. Add that onto the already cost of $560, and it gives you a grand total of $588. She wants to sell the shirts with a 150% markup, so all you do is first find what Michelle really paid for each shirt with tax. Take the total cost of 588 and divide it by the number of total shirts which is 200. 588/200=$2.94 per shirt that Michelle paid. Times that by 1.5% and you get $4.41 per shirt that Michelle is selling.

Answer:

c = 24.17 feet

Step-by-step explanation:

Right Triangles

A right triangle is a special triangle that has an interior angle of 90°.

In right triangles, Pythagora's Theorem is satisfied:

[tex]c^2=a^2+b^2[/tex]

Where c is the hypotenuse (longest side) of the triangle, and a and b are the legs or the smaller sides.

The slide can be thought of as a right triangle whose hypotenuse is the slide itself and the legs are the height of the ladder and distance between the foot of the ladder and the end of the slide.

So we have:

[tex]c^2=22^2+10^2[/tex]

[tex]c^2=484+100=584[/tex]

D

Step-by-step explanation:

The reason D is false is because it states that Sasha can make 2 bags per minute while she cant make 2 bags per minute. She can make half a bag per minute. D is wrong 100%

Answer:

Step-by-step explanation:

Distance covered = speed × time.

Sasha runs at a constant speed of 3.8 meters per second for 1/2 hour.

This means distance covered while running would be

3.8 × 1/2 = 1.9 meters

Then she walks at a constant rate of 1.5 meters per second for 1/2 hour. This means distance covered while walking would be

1.5 × 1/2 = 0.75 meters

Total distance that Sasha covered while running and walking in 60 minutes would be

1.9 + 0.75 = 2.65 meters

Answer:

y = -f(x - 5)

Step-by-step explanation:

the function of the dotted graph is f(x) shifted (or translated) 5 units to the right and then reflected across the x-axis.

shifting it to the right is happening by reducing every x value by 5 (so that we get for x the functional value of x-5).

and reflecting it across the x-axis simply means to flip the sign. everything that was originally above the x-axis is now with the same distance below the x-axis (and vice versa).

therefore, the new

y = -f(x - 5)

Answer:

1 1/8

Step-by-step explanation:

Make this an improper fraction for simplicity: 27/4

Answer:

The last option: The x-intercept becomes negative and the new line intersects the original line.

Step-by-step explanation:

Remember that when finding the x-intercept you set y to 0.

Let's compare the two equations when we solve for x:

0=34x-3          0=-34x-3

1. Add 3 to both sides of the equations

3=34x               3=-34x

2. Divide the coefficients

[tex]\frac{3}{34}[/tex]=x                   [tex]\frac{3}{-34}[/tex]=x

We know that the new slope does not remain the same as stated in the first and third options. In order for two lines to be parallel, the slopes must be exactly the same, so the second option is incorrect. Therefore, the last option is correct.

Answer:

The first term is 3 and the common difference is 2

Step-by-step explanation:

The formula of the sum of the nth term of the arithmetic sequence is

[tex]S_{n}=\frac{n}{2}[2a+(n-1)d][/tex], where

∵ The sum of the first five terms of an arithmetic sequence is 35

∴ [tex]S_{5}[/tex] = 35

→ Substitute The values of n and S in the rule above

∵ 35 = [tex]\frac{5}{2}[2a+(5-1)d][/tex]

∴ 35 = [tex]\frac{5}{2}[2a+4d][/tex]

→ Simplify the right side

∴ 35 = 5a + 10d

→ Switch the two sides

∴ 5a + 10d = 35 ⇒ (1)

∵ The sum of the next five terms is 85

→ To find the sum of the first 10 terms add 85 to [tex]S_{5}[/tex]

∴ [tex]S_{10}[/tex] = 35 + 85 = 120

→ Substitute The values of n and S in the rule above

∵ 120 = [tex]\frac{10}{2}[2a+(10-1)d][/tex]

∴ 120 = 5[2a + 9d]

→ Simplify the right side

∴ 120 = 10a + 45d

→ Switch the two sides

∴ 10a + 45d = 120 ⇒ (2)

Now we have a system of equations to solve it and find a and d

→ Multiply equation (1) by -2

∵ -2(5a) + -2(10d) = -2(35)

∴ -10a + -20d = -70 ⇒ (3)

→ Add equations (2) and (3)

∵ (10a + -10a) + (45d + -20d) = (120 + -70)

∴ 25d = 50

→ Divide both sides by 25 to find d

∴ d = 2

→ To find a substitute d in equation (1) by 2

∵ 5a + 10(2) = 35

∴ 5a + 20 = 35

→ Subtract 20 from both sides

∵ 5a + 20 - 20 = 35 - 20

∴ 5a = 15

→ Divide both sides by 5

∴ a = 3

∴ The first term is 3 and the common difference is 2

Answer:

the y-intercept is 2/5 and the slope is -5

Step-by-step explanation:

Given:

The ratio of the amount of money Kate has to that of Nora is 3 : 5.

After Nora gives $150 to Kate, the ratio of the amount of money Kate has to that of Nora becomes 7 : 9.

To find:

The sum of money Kate had initially.

Solution:

Let the initial amount of money Kate and Nora have are 3x and 5x respectively.

After Nora gives $150 to Kate, the ratio of the amount of money Kate has to that of Nora becomes 7 : 9.

The amount of Kate = 3x+150

The amount of Nora = 5x-150

Now,

[tex]\dfrac{3x+150}{5x-150}=\dfrac{7}{9}[/tex]

[tex]9(3x+150)=7(5x-150)[/tex]

[tex]27x+1350=35x-1050[/tex]

[tex]1350+1050=35x-27x[/tex]

[tex]2400=8x[/tex]

Divide both sides by 8.

[tex]300=x[/tex]

Putting x=300 in 3x, to get the amount of money Kate has initially.

[tex]3(300)=900[/tex]

Therefore, the Kate initially had $900.

Answer:(y=2x+2

A pattern in the shaded parts of the multiplication table is suitable for option b.(we multiply a number times itself to get each shaded number.)

Suppose we can use, option b,

We multiply a number times itself to get each shaded number,

Shaded parts of the multiplication table is ⇒ 1, 4, 9, 16, 25, 36, 49, 64, 81, 100.

We can write,

[tex]x^{2}[/tex] = x * x

Example:

1 = 1 * 1 = 1

4 = 2 * 2 = [tex]2^{2}[/tex]

9 = 3 * 3 = [tex]3^{2}[/tex]

36 = 6 * 6 = [tex]6^{2}[/tex]

49 = 7 * 7 = [tex]7^{2}[/tex]

64 = 8 * 8 = [tex]8^{2}[/tex]

81 = 9 * 9 = [tex]9^{2}[/tex]

100 = 10 * 10 = [tex]10^{2}[/tex]

Hence,

1 = [tex]1^{2}[/tex]

4 = [tex]2^{2}[/tex]

9 = [tex]3^{2}[/tex]

16 = [tex]4^{2}[/tex]

25 = [tex]5^{2}[/tex]

36 = [tex]6^{2}[/tex]

49 = [tex]7^{2}[/tex]

64 = [tex]8^{2}[/tex]

81 = [tex]9^{2}[/tex]

100 = [tex]10^{2}[/tex]
