Solve the exponential equation for x. 625 = 5 (7x-3)A. x = 1
B. x = -1
C. x = 2
D. x = -2

Answers

Answer 1

Answer:

Answer:

A. x = 1

Step-by-step explanation:

$5^(7x-3)=625\n\n5^(7x-3)=5^4\iff7x-3=4\qquad\text{add 3 to both sides}\n\n7x=7\qquad\text{divide both sides by 7}\n\nx=1$

Put in order of smallest to the biggest these numbers 0.56, 0.4, 0.07, 0.34

Answers

In order from smallest to biggest, this is the order in which the following numbers would go --

0.07 (Or, 7%)

0.34 (Or, 34%

0.4 (Or, 40%)

0.56 (Or, 56%)

(Remember, to get the answer, you would multiply each decimal by 100 and then compare them all and put them in order that way. That's how I find it easiest to put decimals in smallest to biggest :D)

80 is 32% of what number

Answers

We set up a proportion: 80/?= 32/100

Cross multiply: 32*?= 80*100
⇒ ?= 80*100/32= 250

80 is 32% of 250.

Answer:

250

Step-by-step explanation:

Part = % * whole

80 = .32x

Solve for x

Divide on both sides coming up with:

80 = .32x

.32 .32

250 = x

How can you use negative numbers to repel resent real-world problems?

Answers

-4000 minus -999999 other numbers

Understand that positive and negative numbers are used together to describe quantities having opposite directions or values (e.g., temperature above/below zero, elevation above/below sea level, credits/debits, positive/negative electric charge); use positive and negative numbers to represent quantities in real-world contexts, explaining the meaning of 0 in each situation.

You Guys Are Smart Please Help!A scuba diver dove from the surface of the ocean to an elevation of −49 9/10
feet at a rate of −15.4 feet per minute. After spending 13.75 minutes at that elevation, the diver ascended to an elevation of −8 9/10
feet. The total time for the dive so far was 20 1/8
minutes. What was the rate of change in the diver's elevation during the ascent? Round your answer to the nearest hundredth.

The rate of change of the diver's elevation was _____ft/min.

Answers

S=v*t=-49.9*13.75=-686.125 feet
ΔS=-686.125-(-8.9)=-677.225 feet
20 1/8-13 3/4= 6 3/8= 6.375 minutes
v=S/t=-677.25/6.375=-106.24 feet per minute
the rate was -106.24 feet per minute of change in the diver's elevation during the ascent
