Rounding to nearest 10s and 100s

2 answers:

8 0

Numbers 5 and over round up to the nearest 10. Numbers like 164 would found to the nearest 10 of 160 because the last number (unit) is below 5, so it rounds down. I hope this helps but you can find tutorials on google good luck!

When you round to the nearest 10 you look at the ones place and see if it is greater or less than 5. If it is greater you round up if less than you leave it the same. For 100 you look at the 10s place and you do the same thing

What is the surface area of a square prism with sides that measure 8 units?

V125BC [204]

Answer:

The surface area of square prism = 384 units squared

Step-by-step explanation:

Explanation:-

Given the square prism side 'a' = 8 units

The surface area of square prism = 2 a² + 4 a h

Given square prism length , width and height also equal identical sides

The surface area of square prism = 2 a² + 4 a h

= 2(8)² + 4 (8)(8)

= 2(64) + 4(64)

= 384 units squared

Final answer:-

The surface area of square prism = 384 units squared

Evaluate the function f(x)= 7.45x + 33.7 at x= -4.3

slavikrds [6]

First, you have to substitute for x, which would make the problem f(x)=7.45(-4.3)+33.7
Now, you just have to use the PEMDAS method (Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction)
f(x)= -32.035+33.7
f(x)=1.665

Find the value of x and y

Natalija [7]

Hello and Good Morning/Afternoon:

Let's take this problem step-by-step:

What does the information want:

value of x
value of y

Let's gather some information:

ΔA'BC' and ΔABC are similar triangles

⇒ Angle B is shared by both triangles

⇒ Angle A' and A are the same, as they are both on parallel

lines, A'C' and AC, and both angles are formed with the

same line AB

⇒ by the Angle-Angle Theorem*, they are similar triangles

If they are similar triangles:

⇒ their side lengths are proportional to each other

let's find x's value

⇒ let's set up a proportion

$\frac{A'B}{AB} =\frac{A'C'}{AC} \\\frac{30}{x+30} =\frac{14}{22} \\14(x+30) = 30*22\\14x + 420 = 660\\14x = 240\\x = 17.143$

let's find y's value

⇒ let's set up a proportion

$\frac{BC'}{BC} =\frac{A'C'}{AC} \\\frac{y}{y+15} =\frac{14}{22} \\22y=14(y+15)\\22y=14y+210\\8y=210\\y=26.25$

Answer:

x= 17.143
y = 26.25

Hope that helps!
