Answer:

Step-by-step explanation:

this simply means that such a letter combination stands for a line that goes through the points with these letters.

and a "ray" means a straight line (not one that goes around a corner). "from this figure" means lines (or connections between points) that are drawn in this graphic.

BA yes

B is just a point, no line. therefore, no.

DBA guys around a corner (from D to B, and then from there to A). therefore, no.

AD would be a straight line, but it is not drawn in the graphic. therefore, no.

ADB is partly not drawn, and it goes around a corner. therefore, no.

CB, CA are both straight lines in the graphic. yes.

Suppose you performed this experiment, and the percentage difference from the accepted value of the density of copper and your v

GREYUIT [131]

Answer:

The answer is 2%

Step-by-step explanation:

Steps to Calculate the Percent Error

Subtract the accepted value from the experimental value.

Take the absolute value of step 1

Divide that answer by the accepted value.

Multiply that answer by 100 and add the % symbol to express the answer as a percentage.

Now let’s try an example problem.

You are given a cube of pure copper. You measure the sides of the cube to find the volume and weigh it to find its mass. When you calculate the density using your measurements, you get 8.78 grams/cm3. Copper’s accepted density is 8.96 g/cm3. What is your percent error?

Solution:

experimental value = 8.78 g/cm3

accepted value = 8.96 g/cm3

Step 1: Subtract the accepted value from the experimental value.

8.78 g/cm3 – 8.96 g/cm3 = -0.18 g/cm3

Step 2: Take the absolute value of step 1

|-0.18 g/cm3| = 0.18 g/cm3

Step 3: Divide that answer by the accepted value.Percent Error Math 3

Step 4: Multiply that answer by 100 and add the % symbol to express the answer as a percentage.

0.02 x 100 = 2

The percent error of your density calculation was 2%.

QUESTION 1 Evaluate −30 ÷ −6. a 5 b −5 c 6 d −6 QUESTION 2 Evaluate 62 ÷ (3 + 9). a3 b4 c12 d21 QUESTION 3 Danny made a mistake

Mashcka [7]

Answer:

A; ?; Line 3

Step-by-step explanation:

Question 1:

-30 divided by -6 is 5.

The negatives cancel each other out.

And 30 divided by 6 is simply 5.

Question 2:

$62\div(3+9)$

Do the operation inside the parenthesis first:

$62\div12$

Divide. 12 does not go into 62 evenly. 12 times 5 is 60, so the answer is 5 remainder 2:

$62\div12=5\text { R}2$

Or in fractions:

$31/6$

(Was there a typo? From what you've given me, the correct answer is not listed.)

Question 3:

So we have to following steps:

$\text{Line 1: } 21+35\div7+6(2)\\\text{Line 2: }21+5+6(2)\\\text{Line 3: }21+11(2)\\\text{Line 4: }21+22\\\text{Line 5: }43$

The mistake is in Line 3. Danny cannot just combine 5+6(2) into 11(2). Instead, he should multiply 6(2) and then add. Thus, the correct solution is:

$\text{Line 1: } 21+35\div7+6(2)\\\text{Line 2: }21+5+6(2)\\\text{Line 3: }21+5+12\\\text{Line 4: }26+12\\\text{Line 5: }38$

Whats the answer is for math btw fidsf

ra1l [238]

Step-by-step explanation:

Since this is a select as many answers that are right, there are obviously many answers that are correct.

First, you get m by itself, so you divide 6 with 300.

So,

6m < 300

___ ___

6 6

m < 50

So the answers are numbers less than 50.

Which are the first four answers:

A, B, C, D
