A science test, which is worth 100 points, consists of 24 questions. Each question is worth either 3 points or 5 points. If x is

xxTIMURxx [149]

Answer:

The test contains 10 three-point questions and 14 five-point questions.

Step-by-step explanation:

We can substitute a definition of one of the variables by rearranging the first equation.

We set the first equation equal to one of our two variables.

$y = 24 - x$

Now we substitute this equality into our second equation

$3x + 5(24 - x) = 100$

During a free fall Swati was accelerating at -9.8m/s^2. After 120 seconds how far did she travel? Use the formula =1/2 * t^2 to

jarptica [38.1K]

Answer:

She traveled 70560 m.

Step-by-step explanation:

Given :

Acceleration (g) = $-9.8m/s^{2}$

Time : 120 seconds .

To Find : Distance traveled

Solution:

Since we are given that there is a free fall .

So, we will use the formula: $d=\frac{1}{2} gt^{2}$

Now put the given values in the formula :

⇒ $d=\frac{1}{2}*(-9.8)*(120)^{2}$

⇒ $d=\frac{1}{2}*(-9.8)*14400$

⇒ $d=\frac{-141120}{2}$

⇒ $d=-70560$

Negative sign shows the direction only.

Hence she traveled 70560 m.

What is the total amount of sap trees produced that day? Please tell me ASAP(as soon as possible) because this lesson is due for

gogolik [260]

Answer: 5 gallons

Step-by-step explanation:

There are 3 x's on the graph for 1/4, so 1/4 times 3=3/4

There are 2 x's on the graph for 3/8, so 3/8 times 2=3/4

There are 4 x's on the graph for 5/8, so 5/8 times 4=5/2

There is only 1 x for 1, so it will remain 1.

So if you add these up,

3/4+3/4+5/2+1

6/4+10/4+1

16/4+1

4+1

There is 5 gallons of sap produced that day.

Hope this helped!
