Simplify the exponential problem 7b^5/b^4

Norma-Jean [14]

Solution:

If the numerator and the denominator have like bases in exponents, then the exponents subtract.

$\frac{7b^5}{b^4} = 7b^5^{-4}$
=> $7b$

Thus, 7b is the simplified expression.

Tony is evaluating his retirement savings. He currently has $318,000 in his account which earns an interest rate of 7% compounde

castortr0y [4]

Answer:

(1) $A(t)= 318000(1.07)^t$

(3)t=16.93 years

Step-by-step explanation:

For a Principal Saved at Compound Interest, the Amount accrued is derived by the function:

$A(t)= P(1+r)^t$

When:

(1)P=$318,000

r=7%=0.07

$A(t)= 318000(1+0.07)^t\\A(t)= 318000(1.07)^t$

(2)See Attachment

(3)If Tony's goal is to save $1,000,000.

$1000000= 318000(1.07)^t\\(1.07)^t=\frac{1000000}{318000} \\(1.07)^t=3.1447\\Log_{1.07}\frac{1000000}{318000}=t\\t=16.93$

(4)The graph confirms the result as the $1000000 Mark on the y-axes occurs almost at x=17

Leah wrote 2 different fractions with the same denominator.Both fractions were less than 1. Can their sum equal 1? Can their sum

Alex777 [14]

Answer:

1. Yes

2. Yes

Step-by-step explanation:

Leah wrote 2 different fractions with the same denominator. Both fractions were less than 1.

1. Can their sum equal 1?

Let Leah fractions be $\dfrac{6}{7}$ and $\dfrac{1}{7}.$ Both these fractions have the same denominators and are less than 1. Find their sum:

$\dfrac{6}{7}+\dfrac{1}{7}=\dfrac{7}{7}=1$

2. Can their sum be greater than 1?

Let Leah fractions be $\dfrac{6}{7}$ and $\dfrac{5}{7}$ . Both these fractions have the same denominators and are less than 1. Find their sum:

$\dfrac{6}{7}+\dfrac{5}{7}=\dfrac{11}{7}=1\dfrac{4}{7}>1$

A recipe calls for 2 cups of flour to make 24 cookies. Write and solve a proportion to find how much flour is needed to make 54

horrorfan [7]

For the answer to the question above,
when you put it into a proportion it would be 2/24 = x/54
multiply 2 and 54 which equals 108
and multiply 24 and x which equals 24x
so you have 24x=108 divide 24x by 24 so you have x standing alone but what you do to one side you have to do to the other so divide 108 by 24 and get 4.5 which is 4 1/2 cups of flour.
So the answer is 2/24 = x/54; x = 4 1/2 cups
