Answer:

50cm or 500mm

Step-by-step explanation:

There are 4 base edges and 4 lateral edges, therefore, multiply the number for both edges by 4 and add.

Considering the fact that we were given two units of measurement, millimeters and centimeters, but we know that there are 10mm (millimeters) in a cm (centimeter) , we can just divide 55 by 10 to get 5.5.

¦

Therefore;

5.5 x 4 = 22

7 x 4 = 28

28 + 22 = 50cm

Hello! answer: 45

Formula for triangles area: base × height ÷ 2

Formula for squares area: base × height

6 × 3 = 18 18 ÷ 2 = 9 since theres 4 identical triangles I'll just multiply by 4 to get all of those triangles area combined so... 9 × 4 = 36

now for the square thats just 3 × 3 and 3 × 3 = 9 now we just add these up for the total surface area so... 36 + 9 = 45 therefore the surface area is 45 HOPE THAT HELPS!

Answer:

121/4

Step-by-step explanation:

To complete the square, we have to work with the coefficient of x

We have to divide the coefficient of x by 2, square it and add it to both sides

So we divide 11 by 2; which is 11/2; then square it

we have this as 121/4

This number is what we are going to have added

Answer:

x=0, y=-2

Step-by-step explanation:

Because 9y appears twice in both equations, you can subtract the equations to eliminate the y variable so you can solve for x:

-7x + 9y = -18

-(4x + 9y = -18)

__________

-11x = 0

x = 0

Since we know x=0, then we plug it back into one of the equations to get the value of y:

-7x + 9y = -18

-7(0) + 9y = -18

0 + 9y = -18

9y = -18

y = -2

Therefore, x=0, and y=-2

Answer:

1:2 or 2:4

Step-by-step explanation:

First lets count the "P"s and "I"s in the word:

I: 4

P: 2

Next, we make a ratio of Ps to Is:

2:4

Now, we need to simplify:

2:4

Divide both sides by 2:

1:2

The answer is 1:2

Answer:

y= -1/5x - 10

Step-by-step explanation: the line has the form:  y=ax+b

the line goes through (-5,-9) --> -5a+b=-9

the line is perpendicular to y=5x+15 --> 5a=-1 --> a=-1/5

therefore (-5). (-1/5) + b = -9 --> b=10

Answer:

a. 4

Step-by-step explanation:

When dividing variables with exponents you subtract the exponents

ex. [tex]\frac{x^5}{x^3} =x^5^-^3=x^2[/tex]

So if we want to find the value of x we simply find what adds to 5 to equal 9

9 - 5 = 4

Hence x = 4

[tex]\frac{c^9}{c^4} =c^9^-^4=c^5[/tex]

Answer:

Answer: 101.03 cm

Step-by-step explanation:

Given

The height of the person is [tex]h=175\ cm[/tex]

Sun is [tex]60^{\circ}[/tex] above the ground

Suppose x is the length of the shadow

From the figure, we can write

[tex]\Rightarrow \tan 60^{\circ}=\dfrac{h}{x}\\\\\Rightarrow x=\dfrac{h}{\tan 60^{\circ}}\\\\\Rightarrow x=101.03\ cm[/tex]

So, the length of the shadow is 101.03 cm

Answer:

it will take 3 yrs for the value of camera to reach $162.

Step-by-step explanation:

Pd = P(1-R/100)^T

162 = 384(1-25/100)^T

162/384 = (3/4)^T

27/64 = (3/4)^T

(3/4)^3 = (3/4)^T

T = 3

Answer:

this represents: exopnential decay, the rate of growth or decay is equal to: 0.25, value of the camera each year is: 0.75, it will take 3 years.

Answer:

Given that a worker earns a 3% increase in her annual salary for each of 5 years, and they plan to continue working in their position for an additional N years, if they continue to earn a 3% increase in their annual salary, to determine what statement could describe the expression that can be used to calculate the total percent increase in their annual salary from the first year to the last year the following calculation should be performed:

1 + 0.03 (interest rate) ^ N (number of years) = final interest rate

1.03 ^ N = Final interest rate

Thus, for example, if it were invested for 5 years, the equation would operate as follows:

1.03 ^ 5 = X

1.16 = X

The total percent increase in their annual salary from the first year to the last year is [tex](1.03)^n[/tex].

A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

As it is given that the annual salary of the worker increases at a rate of 3%. therefore, the salary of the worker increases compounded at a rate of 3% annually. Therefore, the salary of the worker after n number of years can be written as,

[tex]A = P(1+\dfrac{r}{100})^n[/tex]

where A is the final salary of the worker, P is the initial salary of the worker, r is the rate at which the salary is increasing, and n is the number of years.

Substituting the values in the formula,

[tex]A = P(1+\dfrac{3}{100})^n\\\\A = P(1.03)^n[/tex]

Hence, the total percent increase in their annual salary from the first year to the last year is [tex](1.03)^n[/tex].
