Answer:

Option D. \$73.47  

Step-by-step explanation:

In this problem

we have    

B=P(1+r)^{t}  

where  

B is the Final Investment Value   or a Balance

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

in this problem we have  

t=5\ years\\ P=\$50\\ r=0.08  

substitute in the formula above  

B=\$50(1+0.08)^{5}=\$73.47

algol13

Answer:

946.242 milliliters

Step-by-step explanation:

The client drank 6 ounces of orange juice and 4 ounces of coffee for breakfast. We need to convert ounces to milliliters

1 ounce = 29.574 milliliters

6 ounces of orange juice

= 6 × 29.574 = 177.444 milliliters

4 ounces of coffee = 4 × 29.574 = 118.296 milliliters

For lunch, he consumed 8 ounces of tea and 6 ounces of ginger ale.

8 ounces of tea = 8 × 29.574 =236.529 milliliters

6 ounces of ginger ale = 6 × 29.574 =177.444 milliliters

4 ounces of water at 10:00 a.m. and at 2:00 p.m. this means 8 ounces of water.

8 ounces of water = 8 × 29.574 =236.529 milliliters

Total consumption by the client =

177.444 + 118.296 + 236.529 + 236.529= 946.242 milliliters

Lena is 10 years old. She asks her dad how old he is. He tells her that the lowest common multiple of their ages is 14 times the
Ksju [112]

Answer:

  35

Step-by-step explanation:

We know the factors of Lena's age are 2 and 5. The least common multiple must have these factors and the factors of 14, so will at least have factors of 2, 5, and 7.

Apparently, the dad's age is 5·7 = 35.

___

The GCF is 5; the LCM is 70 = 5×14.

_____

Sometimes, I use a little 3-part diagram to think about LCM and GCF. Here, it would look like ...

  (2 [5) 7]

where the numbers in curved brackets (2·5) and the numbers in square brackets [5·7] are factors of the two numbers of concern (Lena's age, her dad's age). The middle number in both brackets [5) is the greatest common factor, and the product of all three numbers is their least common multiple.

Here, the product of outside numbers, 2·7 = 14, represents the ratio of the LCM to the GCF. We know that Lena's age has factors of only 2 and 5, so the numbers in the diagram have to be (2[5)7], where 2 and 7 are on the ends and 5 is in the middle.

Twice a number is 60 more than five times the number. what is the number?
Delvig [45]
Let the number be represented by x
2x=60+ 5x                          -20*2=60+5*-20
2x-5x=5x-5x+60                     -40=60+-100
-3x=60                                      -40=-40
-3x/-3=60/-3
x=-20
Therefore the number is -20
