Answer:

2, 6, 28, 358.01

Step-by-step explanation:

We have to find the fractions of whole numbers.

Number 1:

\frac{1}{5} of 10 = \frac{1}{5} \times (2 \times 5) = 2 (Answer)

Number 2:

\frac{2}{3} of 9 = \frac{2}{3} \times (3 \times 3) = 2 \times 3 = 6 (Answer)

Number 3:

\frac{7}{8} of 32 = \frac{7}{8} \times (4 \times 8) = 7 \times 4 = 28 (Answer)

Number 4:

3 \times 10^{2} + 5 \times 10^{1} + 8 \times 10^{0} + 1 \times \frac{1}{10^{2} }

= 3 \times 100 + 5 \times 10 + 8 \times 1 + \frac{1}{100} {Since a^{0} = 1}

= 300 + 50 + 8 + 0.01

= 358.01 (Answer)

The graph of the function f(x) = –(x + 3)(x – 1) is shown below.
pav-90 [236]

Answer:

The function is negative for all real values of x where

x < –3 and where x > 1.

Step-by-step explanation:

This quadratic function is downward parabola.

It's root are -3 and 1.

Quadratic is positive between -3 and 1.

And negative on R-(-3,1).

shutvik [7]

Answer:

a) 8.8 square centimetres

b) 31.8 square centimetres

c) (3a + 12) square centimetres

d) Area = (2b + 2c + 4) square centimetres

Step-by-step explanation:

a) We have to split the diagram into three separate rectangles as shown below.

The area of A:

Area = 5.3 * 1 = 5.3 square centimetres

The area of B:

Area = 3.3 * 1 = 3.3 square centimetres

The area of C:

Area = 2 * 1 = 2 square centimetres

The area of the shape is the sum of the areas of the three shapes:

Area = 5.3 + 3.3 + 2 = 8.8 square centimetres

b) We have to split the diagram into two separate rectangles as shown below.

Note:(The diagram has conflicting values for 2.6 and 2.1 but I went with 2.6 as it seems more feasible in the diagram)

The area of A:

Area = 3 * 2.6 = 7.8 square centimetres

The area of B:

Area = 6 * 4 = 24 square centimetres

The area of the shape is the sum of the areas of the two shapes:

Area = 7.8 + 24 = 31.8 square centimetres

c) The shape is a rectangle and so its area is:

Area = 3 * (a + 4) = (3a + 12) square centimetres

d) The shape is a trapezium and so its area is:

Area = 0.5(A + B)H

where A =  c cm

B = b + 2 cm

H = 4 cm

The area of the shape is therefore:

Area = 0.5 * (c + b + 2) * 4

Area = 2 * (b + c + 2)

Area = (2b + 2c + 4) square centimetres

15 points. The team won 7/10 of its games and lost the rest. What is the team's win-loss ratio?
timama [110]

Answer:

7 wins to 3 losses, so 7:3, 7/3, or 7 to 3 depending on how you want to phrase it.

FOR 20 POINTS!!!! Please help numbers 18, 19, and 20 i dont get them answers are good but it would be great if you explained the
cluponka [151]
Problem 18)

The distance from J to L is 30 units. We can count out the number of spaces or do subtraction to get 30-0 = 30. I subtracted the number line coordinate of J and L. The result is positive as distance is never negative.

Take 2/3 of this value to get (2/3)*30 = 20 which means that we start at J and add on 20 units to get 0+20 = 20

So the final answer is 20, which is where this point is located on the number line.
----------------------------------------------------------------
Problem 19)

The distance from A to B is 3 units because |-5-(-2)| = |-5+2| = |-3| = 3

Double this value to get 2*3 = 6

Now add 6 units to the coordinate of point A to get
-5+6 = 1

The location of this point is at 1 on the number line.
----------------------------------------------------------------
Problem 20)

From J to I, or vice versa, we travel 5 units. 

Multiply this by 1.5 to get 1.5*5 = 7.5

So we subtract 7.5 units from 0 (the coordinate of point J) getting us 0-7.5 = -7.5

Final Answer: -7.5
Note: this is the midpoint of -10 and -5 on the number line
