How many 2-digit numbers are multiples of both 5 and 7?

SAT
1 answer:
marysya [2.9K]3 years ago
7 0

Answer:

2: 35 and 70

Explanation:

1. The LCM of 5 and 7: <em>35</em>

2. 35 * 2 = 70

3. 35 * 3 = 105, not 2-digit

So, the only 2-digit numbers that are multiples of both 5 and 7 are 35 and 70, so 2.

If f(x)=(x+3)³+4<br> let g(x)=f(x+1)-2<br> find when g(x)=12
Alla [95]

Answer:

Explanation:

g(x) = f(x + 1) - 2

g(x) = (x + 1 + 3)^3 -2

g(x) = (x + 4)^3 - 2

Now what are we supposed to do with this? I'm guessing we are to find what value of x will make g(x) = 12. If I'm wrong, leave a note in the form of a comment.

g(x) = 12

(x + 4)^3 - 2 = 12                 Add 2 to both sides.

(x + 4)^3 = 14                      Take the cube root of both sides.

x + 4 = cubrt(14)

x + 4 = 2.4101                      Subtract 4

x = 2.4101 - 4

x = -1.5899

Which way will water molecules move if a red blood cell is placed in distilled water?.
Stels [109]

Answer:

<u>If you put a red blood cell in distilled water (100% H2O), there will be a net movement of water </u><u>from a region of higher concentration (100%) to a region of lower concentration </u><u>(the cell with 99.15% H2O). The distilled water outside the red blood cell, since it is 100% water and no salt, is hypotonic (it contains less salt than the red blood cell) to the red blood cell. The red blood cell will gain water, swell ad then burst. The bursting of the red blood cell is called hemolysis.</u>

Barbara sells iced tea for $1. 49 per bottle and water for $1. 25 per bottle. She wrote an equation to find the number of bottle
Yuki888 [10]

Answer:

Barbara’s equation did not consider the number of bottles of iced tea.

Explanation:

She made this error because she included 1.25 with the x variable but did not include the x variable next to 1.49.

The x variable is important because it can keep track of how many bottles were sold of each water and tea.

So, this means <u>Barbara’s equation did not consider the number of bottles of iced tea.</u>

The real equations should be 1.25x + 1.49x = 100

Hope this Helps!
