I looked it up and  got this........

What is 260 rounded to the nearest ten?
Here we will tell you what 260 is rounded to the nearest ten and also show you what rules we used to get to the answer. First, 260 rounded to the nearest ten is:
260
Remember, we did not necessarily round up or down, but to the ten that is nearest to 260.
When rounding to the nearest ten, like we did with 260 above, we use the following rules:
A) We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.
B) We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.
C) If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.

Galina-37 [17]

Answer:

if you meant to put (t-3)^{2}, then the answer is 7

Step-by-step explanation:

h=-2(t-3)^{2}+32

solve for t

0=-2(t-3)^{2}+32

subtract 32 from both sides

-32=-2(t-3)^{2}

divide both sides by -2

16=(t-3)^{2}

find suare root of 16

4= t-3

add 3 to both sides

7 = t

Question 3
Elza [17]

Answer:

Perimeter is 126cm and area is 972cm^2

Step-by-step explanation:

Scale factor means you multiply the dimensions by the factor. In this case 4.5

The width 6cm becomes 27cm. The length 8cm becomes 36cm.

Perimeter = 2*L + 2*W, L is length and W is width.

P=27*2cm+36*2cm\\P=54cm+72cm\\P=126cm

Area = L*W

A=27cm*36cm\\A=972cm^2

Is (ab)² equivalent to ab², why or why not?
Montano1993 [528]

(ab)² and ab² are not equal. When you have something in parentheses being squared, you have to square everything inside, so in the case of (ab)², you have to "distribute" the ² to both variables inside. That gives you a²b², not just ab².

If the abstract way is kind of confusing for you, just pick two random numbers for a and b and plug them in to test it. Say a = 3 and b = 4. Then

(3*4)² = 3*4²

(12)² =  3*16

144 ≠ 48

Answer:

x = 112

Step-by-step explanation:

1/8x + 2 = 16

Subtract 2 from both sides

1/8x = 14

Multiply both sides by 8

x = 112
