Find the surface area of a square pyramid with side length 1 mi and slant height 4 mi.

Answer:

Step-by-step explanation:

Explanation:

Marc is assembling gift bags. For every 2 pencils he places in the bag, he uses 3 stickers.

For 4 pencils, he uses 3 + 3 = 6 stickers

For 6 pencils, he uses 6 + 3 = 9 stickers

For 8 pencils, he uses 9 + 3 = 12 stickers

\(\\ \tt\hookrightarrow a/3=-5a\)

\(\\ \tt\hookrightarrow a=-15a\)

Only 0 can be the solution

#b

\(\\ \tt\hookrightarrow 12-b=12.5b\)

\(\\ \tt\hookrightarrow 12=13.5b\)

\(\\ \tt\hookrightarrow b=12/13.5\)

\(\\ \tt\hookrightarrow b=0.8\)

#c

\(\\ \tt\hookrightarrow -0.1=-10c\)

\(\\ \tt\hookrightarrow 10c=0.1\)

\(\\ \tt\hookrightarrow c=0.01\)

Answer:

678.24

Step-by-step explanation:

First, we have to find the area of 1 cylinder(pi x r^2 x h), which i got as 226.08 then we multiply by 3 because there are 3 cylinders. 226.08 x 3 = 678.24

Answer: Hope this helps you!

Step-by-step explanation:

First, I started off with the equation of the area of a cylinder

Area = π * radius^2 * height

Now I will go on and substitute

Area = 3.14 * 3^2 * 8

And now I will start solving

Area = 3.14 * 3^2 * 8

(3^2 = 3*3 = 9)

Area = 3.14 * 9 * 8

(9*8 = 72)

Area = 3.14 * 72

Area = 226.08

The area of 1 cylinder is 226.08, however we need to find the area of the whole composite figure which is made up of 3 cylinders.

226.08 * 3 = 678.24

Answer:(x,y)=(1,1)

Step-by-step explanation:     y=2x - 1 , 5x - 4y=1

                                                y=2x-1

5x-4y=1

5x-4(2x-1)=1

x=1

y=2x+1-1

y=1

(x,y)=(1,1)

1=2 x 1 - 1

5 x 1 - 4 x 1 = 1

1=1

1=1

therefore the anwser would be (x,y)=(1,1)

Answer:

(x,y)=(1,1)

Answer:

4.9

Step-by-step explanation:

for this I used the sine rule so I did 6/sin 70 × sin 50

you can put :they both have whole numbers

Step-by-step explanation:

Answer:

Step-by-step explanation:Situation A: The hang glider descended 33.57 feet and again ascended 14.98. So 33.57 - 14.98 = 18.58. So now the hang glider is at 18.58 feet

Situation B: Initially they gained 7 2/5 yards and then lost 3/5 yards.

7 2/5 yards can be written as 37/5. As they lost 3/5 yards, 37/5 - 3/5 = 34/5. So the remaining yards are 34/5 yards.

Situation C: Hiker walked 3 1/6 miles and then 2 1/2 miles. So the total distance is 3 1/6 + 2 1/2 = 5 4/6 miles.

Situation D: Total amount earned is $23.66 + $15.84 = $39.5.

I took some paper and cut it to the shapes and folded them to see which ones are the answer and got those 2. :3

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

Answer:

4

Step-by-step explanation:

1/6x = 2/3  Multiply each sides by 6

x = \(\frac{2}{3}\) x \(\frac{6}{1}\)

x = 4

Answer:

Step-by-step explanation:

if they used 1 liter of sauce on each pizza, it would be 1x=2/3.

So if we use this for 1/6 of a liter of sauce on each pizza…

(x is the number of pizza’s they make.)

= \(\frac{1}{6}\)х=\(\frac{2}{3}\)

x6 on both sides

= 1x=9

Therefore, the pizza restruant made 9 pizzas.

Answer:

48.3

Step-by-step explanation:

multiply 7by 2.3 then multiply the whole thing by3 and that’s your answer

Answer: 48.3

Step-by-step explanation:

Explanation:

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

Answer:

341/11 = 31 is the arithmetic mean.

Answer:

310 balcony tickets were sold

Step-by-step explanation:

Part 1:

X=the number of orchestra seats sold

Y=the number of balcony seats sold

980=the total of tickets sold

X+Y=980

Part 2:

Orchestra seats cost $50

Balcony Seats cost $35

Total money collected $44,350

50X+35Y=44,350

X+Y=980

Y=980-X (substitute y in your second equation)

50X+35(980-X)=44,350

50X+34,300-35X=44,350

50X-35X=44,350-34,300

15X=10,050

X=670

Y=980-X

Y=980-670

Y=310

Check

50X+35Y=44,350

50(670)+35(310)=44,350

Answer:

The individual income tax (or personal income tax) is a tax levied on the wages, salaries, dividends, interest, and other income a person earns throughout the year. The tax is generally imposed by the state in which the income is earned.

Step-by-step explanation:

Payroll tax refers to the taxes that are deducted from an employee's wages or salary by their employer.

We have to give that,

To define Payroll tax.

Now, Payroll tax refers to the taxes that are deducted from an employee's wages or salary by their employer.

These taxes are withheld to fund various government programs and services.

Payroll taxes typically include federal, state, and local income taxes, as well as Social Security and Medicare taxes.

The amount of payroll taxes deducted from an employee's paycheck depends on factors such as income level, tax brackets, and the tax rates set by the applicable government authorities.

These taxes are then remitted by the employer to the appropriate tax agencies on behalf of their employees.

They are specifically related to employment income and play a crucial role in funding important government initiatives and social programs.

Answer:

Step-by-step explanation:

Given poster boards are $0.75 each, you want to know the number purchased for $4.50. Given brushes are $0.95 and jars of paint are $0.99, you want to know the number of each purchased for $7.80.

The total price is the quantity times the price each:

  4.50 = q × 0.75

  q = 4.50/0.75 = 6

Isabella buys 6 poster boards.

Compatible numbers for the costs of brushes and paint are each 1. A compatible number for the total purchase is 8. This tells us Isabella bought 8 items for 7.80. This gives two equations in two unknowns:

  0.95b +0.99p = 7.80

  b + p = 8

Substituting for b, we have ...

  0.95(8 -p) +0.99p = 7.80

  `7.60 +0.04p = 7.80 . . . . . . simplify

  0.04p = 0.20 . . . . . . . . . . . subtract 7.60

  p = 0.20/0.04 = 5

  b = 8 -5 = 3

Isabella buys 3 paint brushes and 5 jars of paint.

Check

0.95(3) +0.99(5) = 2.85 +4.95 = 7.80 . . . . answer checks OK

__

Additional comment

Note that we do not need to "guess and check" once we know the number of items purchased.

Or, we can "guess" without the business of compatible numbers by realizing the number of jars must be a multiple of 5 if the total purchase is a multiple of 5 cents. That leaves one possibility, since 10 jars is too many, and 0 jars is not enough.
