Answer:

265

Step-by-step explanation:

calculate the mean/average by adding 260 + 270 + 280 + 250

(which is 1,060)

then divide that by 4 (the number of numbers)

1,060 ÷ 4 = 265

Answer:

There are an average of 265 students present.

Step-by-step explanation:

  1. Count all the present student numbers together: 260 + 270 + 280 + 250 = 1060
  2. Divide the sum of all the present student numbers by the number of days: 1060÷4=265 students present on average.

Please help me determine the length in its simplest form
nadya68 [22]

Answer:

AB = 4.5 units

Step-by-step explanation:

Let the length of AB be x.

<em><u>GIVEN</u></em><em> :-</em>

  • BC = 3 units
  • CD = 4 units
  • ED = 6 units
  • BD || AE

<em><u>TO FIND</u></em><em> :-</em>

  • The length of AB.

<em><u>FACTS TO KNOW BEFORE SOLVING</u></em><em> :-</em>

<em><u>Basic Proportionality Theorem</u></em> :-

  • If a line is drawn parallel to one side of a triangle to intersect the other two sides in distinct points , the other two sides are divided in the same ratio.

<em><u>PROCEDURE</u></em><em> :-</em>

According to Basic Proportionality Theorem ,

\frac{CB}{AB} = \frac{CD}{ED}

=> \frac{3}{x} = \frac{4}{6}

=> x = \frac{3 \times 6}{4} = \frac{18}{4} = 4.5

∴ AB = 4.5 units

Which of the given values is a solution to the equation 8c+3=−40c−10?
solniwko [45]

Answer:

\boxed{\bold{C \ = \ \frac{-13}{48}  \ or \ -0.27083333333}}

Explanation:

8c + 3 = −40c − 10

[ Step 1: Add 40c to both sides ]

8c + 3 + 40c = −40c − 10 + 40c

48c + 3 = −10

[ Step 2: Subtract 3 from both sides ]

48c + 3 − 3 = −10 − 3

48c = −13

[ Step 3: Divide both sides by 48 ]

48c / 48 = −13 / 48

C = -13 / 48 or -0.27083333333

y=±√36

y=±6

y=-6 and 6 so B and D is the answer.
