Answer:

A. 18.2

Step-by-step explanation:

b^2 + 14^2 = 23^2

b = sqrt(333) = 18.248

Answer:

36 units³

Step-by-step explanation:

The volume of a rectangular prism is given by

Volume, V = l * w * h, where

V = volume like I had stated

L = length of the prism

w = width of the prism

h = height of the prism

Going by the aforelisted parameters, we can apply them to the formula to get our answer straight

Volume, V = 3 * 6 * 2

Volume, V = 36 units³

Therefore, the volume of the prism is 36 units³

Answer:

Number one is 54

Step-by-step explanation:

a) 8x + 5y

b) 11x - 8y

Combine like terms in each expression and you'll get the answer! You can't simplify any further from here, so there's your answer.

A) First, calculate the volume of cuboid A.

3x2x8 = 48 cm cubed

Cuboid B:

6x2xh = 48 cm cubed

Simplify:

12xh = 48 cm cubed

12x4 = 48 cm cubed

So, the height of cuboid B is 4 cm

B) Multiply the volume by 1,000:

4.5 L = 4,500 cubic cm

Answer: Independent variable = c

Dependent variable = v

Step-by-step explanation:

Given variables:

c = the number of Nora's coworkers who attend the picnic

v = the number of veggie burgers

Here the number of burgers required is dependent on the number of Nora's coworkers who attend the picnic.

Therfeore, Independent variable = c

Dependent variable = v

Answer:

There are 10 hours and 45 minutes until the bus leaves.

Answer:

In between the 10pm to 8 am =10 hours

In between the gap of 9:45 to 10 pm =15 min left

In between 8 and 8:30 am =30 min left

So 10hr and 45 min is the answer

Answer:

B.9

Step-by-step explanation:

you are just trying to find the number to make it equal to 18

Answer:

152cm^2

Step-by-step explanation:

Find area of whole rectangle = 12 * 18 = 216cm^2

Find area of smaller square = 8 * 8 = 64cm^2

Take away the larger area from the smaller area = 216 - 64 = 152cm^2

(^2 indicates cm squared)

Hope this helps :)

Answer:

Area of the given figure is 152 sq.cm

Step-by-step explanation:

area of given figure (A)

= area of rectangle - area of minor square

=》A = (12 × 18) - (8 × 8)

=》A = 216 - 64

=》A = 152 sq.cm

Answer:

do you know how to calculate c

Step-by-step explanation:

Answer:

False

Step-by-step explanation:

Answer:

it's actually reverse; an expression is an equation without an equal sign so false lol

Answer:

x=9

Step-by-step explanation:

alright so first we eliminate the -15 and to do that we add 15 on both sides:

-3x-15+15=12+15

-3x=27

Now we divide 3 on both sides to make the equation equal to x

[tex] \frac{-3x}{-3} = \frac{27}{-3} [/tex]

x=9

And that's your answer, you're welcome :)

Answer:

B

Step-by-step explanation:

f(x) = 3x - 7

g(x) = 8x + 2

f(x) * g(x) = (3x - 7)(8x + 2)     {Use FOIL method}

              = 3x*8x + 3x *2  +(-7)*8x + (-7)*2

             = 24x² + 6x  - 56x - 14      {Combine like terms}

             =24x² - 50x - 14  

Answer:

-14°C

Step-by-step explanation:

Given that,

The mean temperature for the first 4 days in January was -4°C.

The mean temperature for the first 5 days in January was -6°C.

Mean = sum of observations/no. of observations

For first 4 days,

[tex]-4=\dfrac{S_4}{4}\\\\S_4=-16\ ...(1)[/tex]

For first 5 days,

[tex]-6=\dfrac{S_4+T}{5}\\\\S_4+T=-30\ ..(2)[/tex]

Let the temperature on 5th day is T. So,

Put S₄ = -16 in equation (2).

-16 + T = -30

T = -30+16

T = -14°C

So, the temperature on the 5th day is -14°C.

Answer:

12x+16y

Step-by-step explanation:

I believe this is the answer

Answer:

The length of the hypotenuse of a right triangle can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.

Answer:

c = 3

Step-by-step explanation:

12 divided by 4 is 3

Answer:

C= 3

Step-by-step explanation:

Potted plants ordered last year = 6,57,230 (Indian Place Value System)

Pecentage of plants deducted = 10%

10% of 6,57,230 = 10/100 × 6,57,230

or, it can also be written as -

10/10 × 65,723

or,

65,723

Therefore, potted plants odered this year is 65,723

By the way, I'm an Indian : )

Answer: 47cm

Step-by-step explanation:

Thw circumference of a circle is given as: = 2πr or πd

where

π = 3.142

d = diameter = 15 meters

Circumference = πd = 3.142 × 15

= 47.13 cm

= 47cm

x = 40

Answer: A 128 square sm

Step-by-step explanation:

So the wedge consists of a square and a triangle. We need to find the area of both using 2 formulas:

A=1/2bh for triangle

A= l*w for square

Starting with the square 8*10=80 so the area of the square is 80 square cm

Now the triangle is 12*8/2 so = 48 square cm

So add the two to get 48+80= 128 Square centimeters which is choice A
