Step-by-step explanation:

2/4*4/8 can be simplified to 1/2*1/2, the product of which is 1/4! Multiply the numerators by each other and the denominators by each other. 1*1 is 1 and 2*2 is 4.

Remember that a fraction multiplied by another fraction is like dividing, the product will get smaller.

Multiplying something by 1/2 for example is like dividing by 2.

Hope this helped!

➷ First, you can simplify the fractions.

2/4=1/2

4/8=1/2

Then, you multiply them.

1/2*1/2=1/4

Final answer:

1/4

Debra plans to invest $2,250 for 10 years. She can invest in a savings account that pays 4% simple intrest or a savings account

Diano4ka-milaya [45]

Answer:

$\$180.55$

Step-by-step explanation:

step 1

Simple interest

we know that

The simple interest formula is equal to

$A=P(1+rt)$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=10\ years\\ P=\$2,250\\r=4\%=4/100=0.04$

substitute in the formula above

$A=2,250(1+0.04*10)$

$A=2,250(1.4)$

$A=\$3,150$

step 2

Interest compounded annually

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=10\ years\\ P=\$2,250\\r=4\%=4/100=0.04\\n=1$

substitute in the formula above

$A=2,250(1+\frac{0.04}{1})^{1*10}$

$A=2,250(1.04)^{10}$

$A=\$3,330.55$

step 3

Find the differences between the two final amounts

$A=\$3,330.55-\$3,150=\$180.55$

5g−2≤ 3g+8 3g+8 it says to solve for g.

Bess [88]

Answer:g is greater than or equal to 6g + 18/5, or g >_ 6g + 18/5

Step-by-step explanation: 5G- 2 <_ 6g + 16

Add 2 to the 16. 5g <_ 6g + 18.

Divide 5 to both sides. g >_ 6g + 18/5

What is the approximate percent change in a temperature then went down from 120ﾟ to 100ﾟ the person changes approximately 17% th

Zanzabum

Answer:

The answer is 17%

explanation:

One way to find percents is to multiply the number you're trying to find the percent of (120) by whatever percent you're looking for (0.17, 0.2, 0.8, etc) If you multiply 120*0.17, you'll get about 20, which is how much was the amount of degrees lost.

Find the value of each of these quantities. C(5,3) C(8,8) C(12,6)

Paul [167]

$C^n_k= \frac{n!}{(n-k)!c!} 
\\
\\C^5_3= \frac{5!}{(5-3)!3!} = \frac{5!}{2!3!} = \frac{5\times4\times3}{3\times2\times1} =10
\\
\\C^8_8= \frac{8!}{(8-8)!8!} = \frac{8!}{0!8!} = \frac{8!}{1\times8!}=1
\\
\\C^{12}_6= \frac{12!}{(12-6)!6!} = \frac{12!}{6!6!} = \frac{12\times11\times10\times9\times8\times7}{6\times5\times4\times3\times2\times1} =\frac{11\times3\times4\times7}{1} =924$

The base and the height of a rectangle are represented by the expressions below.

PIT_PIT [208]

The length of the base is 27 and the length of the height is 17.

To find the answer, you need to add up each side twice and set it equal to 88.

x-6+x-6+x+4+x+4=88

That is equal to: 4x - 4 = 88

Add 4 to both sides: 4x = 92

Divide by 4: x = 23

Now plug 23 in for x:

Base: 23 + 4 = 27
Height: 23-6=17
