250 * .42 = 105

Answer:

105

Step-by-step explanation:

What is 42% of 250?

Let's break this question down.

We have:

42% – A percent is a fraction out of 100. 100% being fully complete. We can express 42% as 42/100 or 0.42.

of – This symbolizes multiplication.

250 – This is our total.

Now let's set up an equation.

42% of 250

0.42 • 250 = ?

Step-by-step explanation:

Answer:

256

Step-by-step explanation:

4^4^4 = 4^(4^4) = 4^256

so written in base 4, there will be 256 zeroes after a 1.

This translates to approximately 154 digits in decimal.

Just like 2^2^2 =  2^4

there will be four zeroes after a 1.

2^2^2=2^(2^2) = 2^4 = 16 = 10000 (16 in base 2).

Answer:

18-3*5+32÷4

=18-3*5+8

=18-15+8

=26-15

=11

Step-by-step explanation:

use BODMAS rule

• 18- 3× 5+ 32÷ 4

= 18- 3× 5+ 8

= 18- 15+ 8

= 18+ 8- 15

= 26- 15

= 11

Answer/Step-by-step explanation:

A. The quadrilateral cam be named using the letters of the vertices. Thus, it is named as: quadrilateral LMNP

B. 82° + (3x - 1)° = 180° (adjacent angles are supplementary)

Solve for x

82 + 3x - 1 = 180

Add like terms

81 + 3x = 180

Subtract 81 from both sides

3x = 180 - 81

3x = 99

x = 99/3

x = 33

C. Opposite angles in a quadrilateral are equal. Therefore,

m<L = (3x - 1)°

Plug in the value of x

m<L = 3(33) - 1

m<L = 99 - 1

m<L = 98°

Answer:

an = 8n − 65 is the correct answer

Answer:

B

Step-by-step explanation:

180 - (25 + 55) = 180 - 80 = 100°

Answer:

Step-by-step explanation:

As an aside, I don't know why Americans don't use a debit card. Usually to figure out what the monthly interest is, you divide the yearly interest by 12

14.25 / 12 = 1.875  and you keep all the decimals.

1350 * 1.875 / 100 = 16.03 is what you save, but there is more. It seems very tiny, but don't be fooled. The credit card company certainly isn't. They will likely round up to 16.04 just so hackers won't make anything if they break into someone's account.

16.04 doesn't seem like much to pay, but realize that if you had to pay it every month, it would be 192.48 a year. That on 1350 is usury.

Answer:

12

Step-by-step explanation:

this equation can be derived from the question

55 - 4x < 10

< = less than

x = number of days

solve for x

55 - 10 < 4x

45 < 4x

x < 11.25

at the 11th day, there would be 11 keys left

on the 12th day, there would be 7 keys left

the correct answer is  12 days

Answer:

x= 4, y = -1

Step-by-step explanation:

2x-3y=11

3x+3y=9

do addition and you should get

5x=20

x=4

plug in x into any equation

12+3y=9

3y= -3

y=-1

Answer:

Step-by-step explanation:

Two cylinders are similar. The heights of the cylinders are 15 cm and 12 cm. If the surface area of the smaller cylinder is 487 cm square. find the surface area of the larger cylinder.

Height of the smaller cylinder = 12cm

Area of the smaller cylinder = x

Height is the bigger cylinder = 15cm

Area of the bigger cylinder = 487cm²

We can find the radius of the bigger cylinder

Radius of the bigger cylinder = 4.07 cm

Hence: we form our proportion to find radius of Smaller cylinder

12/15 = x/4.07

Cross Multiply

15x = 12 × 4.07

x = 12 × 4.07/15

x = 3.256 cm

Answer: The volume of given substance is [tex]2.2 cm^{3}[/tex].

Step-by-step explanation:

Given: Density = 10.7 [tex]g/cm^{3}[/tex]

Mass = 23.54 g

Density of a substance is the mass of substance divided by its volume.

Mathematically, [tex]Density = \frac{mass}{volume}[/tex]

Substitute the values into above formula to calculate volume as follows.

[tex]Density = \frac{mass}{volume}\\10.7 g/cm^{3} = \frac{23.54 g}{volume}\\volume = \frac{23.54 g}{10.7 g/cm^{3}}\\= 2.2 cm^{3}[/tex]

Thus, we can conclude that the volume of given substance is [tex]2.2 cm^{3}[/tex].

To find the value of x , lets assume that both the triangles are similar to each other. As they are similar , their sides are proportional to each other i.e. :-

[tex]\frac{KJ}{JL} = \frac{QR}{QS}[/tex]

[tex]=> \frac{3}{x} = \frac{12}{x + 6}[/tex]

Answer:

B) 28 in

Step-by-step explanation:

Pythagorean thm formula:

a² + b² = c²

Given:

b = 45

c = 53

Work:

a² + b² = c²

a² + 45² = 53²

a² + 2025 = 2809

a² = 2809 - 2025

a² = 784

[tex]\sqrt{a^2} =\sqrt{784}[/tex]

a = 28

Answer:

Delivery cost per minute = $0.3 per minute

Step-by-step explanation:

Given:

Cost of pizza = $12

Total amount pay by Ruby = $15

Time taken for delivery = 10 minutes

Find:

Delivery cost per minute

Computation:

Total amount of delivery = Total amount pay by Ruby - Cost of pizza

Total amount of delivery = 15 - 12

Total amount of delivery = $3

Delivery cost per minute = Total amount of delivery / Time taken for delivery

Delivery cost per minute = 3 / 10

Delivery cost per minute = $0.3 per minute
