If 70g is 100%.... 48g is taken away... what is the percentage of the remaining 22g. Rounded to the nearest whole number?

1 answer:

8 0

we are given with 70 grams and is said that 48 grams is taken away. This is equal to 22 grams. To find the mass percentage, we divide the remaining mass and divide by the total mass. The remaining 22 grams is equal to 22/70 * 100 percent equal to 31.43 percent.

At a local daycare, there is a ratio of 7 children to every 2 caretakers. If there are 189 total children, then how many are peo

liq [111]

Answer: 243 people

Step-by-step explanation:

ration of 7 children to every 2 caretakers, and there are 189 children. So, since ratio of children is 7, divide 189 by 7 and get 54. Then multiply by 2 since that is the ratio for caretakers to get 54 caretakers. You can check these numbers by putting in the calculator 189/54, it simplifies to 7/2. Add 54 and 189 to get total number of people which is 243.

Which of the following is an element

zaharov [31]

We can easily enumerate E and F:

$E = \{ 1,4,9 \}$

$F = \{ 2,4,6,8 \}$

The intersection $E \cap F$ is a set composed by all the element belonging to both E and F, i.e. 4.

The intersection of this set with D works in the same way, but it's actually a trivial one, since $E \cap F$ is a subset of D. In fact, D is the set of all integers, while 4 is a particular integer. And in general, if A is a subset of B, then the intersection between A and B is A itself, so the final answer is

$D \cap (E \cap F) = \{4\}$

A straight line passing via (2,5) and (26/3,0) where should it intersect the x axis and the y axis

nexus9112 [7]

Answer:

( 2 , 5 ) and ( 26 /3 , 0 )

Step-by-step explanation:

Find the equation using the two points.

Use y = m x + b to calculate the equation of the line, where m represents the slope and b represents the y-intercept. To calculate the equation of the line, use the y = m x + b format.

Slope is equal to the change in y over the change in x , or rise over run.

The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise).

$m=\frac{y_{2-y_{1} } }{x_{2-y_{1} } }$
