There were 5000 mangoes in the basket, 3750 of them were good.

% mangoes

25% ---------- 1250

75% ----------- X

25x = 1250.75

25x = 93750

X = 93750/25

X = 3750 mangoes

3750+1250 = 5000

Is the simplified form of 2-3 + 3.3 rational?<br> Yes<br> No

N76 [4]

Answer:

YES IT IS

Step-by-step explanation:

2-3 + 3.3

= -1 + 3.3

= -4.3

We learn that:

Rational number: rational number is the number that can be written as a/b (a and b would be intergers and b is not equal to 0). Rational number would be most of numbers we use in out life, except Square root and Pi number.

In this case, -4.3 can be write as -43/10

So YES it would be a rational number

Hope this helped :3

The length of a rectangle board is 10 centimeters longer than its width. The width of the board is 26 centimeters. The board is

Troyanec [42]

Answer:

Area of each piece = 104 $cm^{2}$

Possible dimensions are 26 cm by 4 cm, 13 cm by 8 cm.

Step-by-step explanation:

Given that:

Dimensions of the rectangular board as:

Length of the board is 10 cm longer than its width.

Width of the board = 26 cm

Length of the board = 26 + 10 = 36 cm

The rectangular board is divided into 9 equal pieces.

To find:

Area of each piece and

the possible dimensions of each piece = ?

Solution:

First of all, let us calculate the area of bigger rectangular board.

Area of a rectangle is given by the following formula:

$Area = Length \times Width$

Area = 26 $\times$ 36 $cm^2$

Area of each smaller rectangle = $\frac{26\times 36}{9} = 104\ cm^2$

To find the possible dimensions, we need to find the factors of 104.

104 = 26 $\times$ 4

104 = 13 $\times$ 8

Therefore, the Possible dimensions are 26 cm by 4 cm

and

13 cm by 8 cm.

Find the value of x in this figure

MArishka [77]

Answer: 35
Each triangle adds up to 180 degrees by adding the two angles that you already have the value of (37+108) and subtract it from 180 to get the final angle(x) you get 35

Therefore x=35 :)

Given a+b=7 and a–b=3, find:<br> 3^a÷3^b<br>

Mama L [17]

Answer:

a= -2 and b=3

Step-by-step explanation:

Step 1) Solve the first equation for a:

a + 3b = 7

a + 3b - 3b = 7 - 3b

a + 0 = 7 - 3b

a = 7 - 3b

Step 2) Substitute(7 - 3b) for a in a second equation and solve for b:

2a = b - 7 becomes:

2(7 - 3b) = b-7

(2 multi.7) - (2 multi.3b)= b-7

14 - 6b = b - 7

14 + 7 - 6b + 6b = b + 6b = b + 6b - 7 +7

21 - 0 = 1b + 6b - 0

21=(1 + 6)b

21 = 7b

21 /7 = 7b/7

3 = 7b/7

3 = b

b = 3

Step 3) Substitute 3 for b in the solution to the first equation at the end of Step 1 and calculate a :

a = 7 - 3b becomes:

a = 7 − ( 3 ⋅ 3)

a = 7 − 9

a = − 2
