4.82 × 10⁻⁴
Explanation:Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Step-by-step explanation:
3. since the two triangles are similar, set up a proportion:
x+8/3x-9=24/28
*cross multiply*:
28(x+8)=24(3x-9)

First, this figure takes place half of the circle. So we are dealing with a semi circle.
Angle C is inscribed angle in the semi circle. A semi circle measure 180 degrees. Since Angle C is inscribed, It measures 90 degrees.
This theorem proves this
If an angle is inscribed in a semicircle, it will be half the measure of a semicircle (180 degrees), therefore measuring 90 degrees.
Solve for x

Account A: $300 monthly deposits, interest rate is 4.2%. Account B: $250 monthly deposits, interest rate is 5.1%. Which account will have a greater value at the end of 15 years?
a. Account A will be greater than Account B.
b. Account B will be greater because the interest rate is higher.
c. They will be worth about the same.
d. Not enough information.
Answers
Answer:
A
Step-by-step explanation:
We have to determine the future value of the annuity to determine which account has a greater value
Future value = Amount x annuity factor
annuity factor = Annuity factor = {[(1+r)^n] - 1} / r
Account A = 300 x[ (1.042)^15 - 1 ] / 0.042 = $6097.14
Account B = 250 x[ (1.051)^15 - 1 ] / 0.051 = $5435,42
Account A will be greater

Step-by-step explanation:
Hello There!
create an equation
x + 51 + 60 + 80 = 180
combine like terms
51 + 60 + 80 = 191
x + 191 = 180

A mafia hideout was just raided and two large groups of criminals escaped. One group filled 8 cars and 8 vans with a total of 240 people. The second group filled 4 cars and 1 van with a total of 54 people.
Answers
Answer:
Number of people in each car = x = 8
Number of people in each van = y = 22
Step-by-step explanation:
Let
Number of people in each car = x
Number of people in each van = y
8x + 8y = 240 (1)
4x + y = 54 (2)
From (2)
4x + y = 54 (2)
y = 54 - 4x
Substitute y = 54 - 4x into (1)
8x + 8y = 240 (1)
8x + 8(54 - 4x) = 240
8x + 432 - 32x = 240
8x - 32x = 240 - 432
-24x = -192
x = -192/-24
x = 8
Substitute x = 8 into (2)
4x + y = 54 (2)
4(8) + y = 54
32 + y = 54
y = 54 - 32
y = 22
Number of people in each car = x = 8
Number of people in each van = y = 22
A 4-L water filter is used to fill 200 mL cups and three 750 mL drink bottles How much water is left in the water filter
Answers
Answer:

4 L = 4 * 1000 mL = 4000 mL
200mL cups filled = 1 ; 200 mL
750mL cups filled = 3 ; 750 * 3 = 2250 mL
Total = (200 + 2250) mL = 2450 mL
Water left in filter :
