I need help with this please

The area of the first one would be the area of the rectangle minus the area of the circle, so 18*8 - (pi*3*3). That's equal to around 115.7257 inches squared.

The area of the second one would be the area of the triangle plus the area of the semicircle, so [(4*5)/2]*[(pi*2*2)/2]. That would be 20pi, or around 62.8319 ft squared

I'm not sure about the third one. Is it a trapezoid?

A pile of sand has a weight of 90kg.The same is put into a small bag, a medium bag and a large bag in the ratio of 2:3:7.Work out the weight of sand in each bag

Answers

Remark

This requires some sort of constant that each of the ratio members is multiplied by.

Call the constant x

Equation

2x + 3x + 7x = 90 Add the left hand side

Solution

12x = 90 Divide by 13

x = 90 /12

x = 7,5

Answer

2x = 2 * 7.5

2x = 15

3x = 22.5

7x = 52.5

Sum = 90 as it should be

A system of linear equations is shown below 5x = 3y - 2
y= x + 4
What is the x-coordinate of the solution?

A. 2
B. 4
C. 5
D. 1

Answers

If you would like to find the x-coordinate of the solution, you can calculate this using the following steps:

5x = 3y - 2
y = x + 4
_________
5x = 3 * (x + 4) - 2
5x = 3x + 12 - 2
2x = 10
x = 5

The correct result would be C. 5.

What is the probability of not drawing a green marble from a jar containing 7 red, 4 green, 3 white, and 9 blue marbles?

Answers

$7+4+3+9$
$11+12$
$23$

$(23)/(23) - (4)/(23)$

$(23-4)/(23)$

$(19)/(23)$ $chance$

Answer:

Probability of not drawing a green marble is 19/23.

Step-by-step explanation:

A jar is containing 7 red, 3 white, and 9 blue marbles.

Then the probability to draw a green marble will be = Numbers of green marbles/ Total numbers of marbles of all colors

P(G) = 4/(7 + 4 + 3 + 9)

P(G) = 4/23

Now the probability of not drawing a green marble = 1 - probability of drawing a green ball

P = 1 - 4/23 = 19/23

Therefore answer is 19/23.

A small toy car costs $3 a large toy car costs 5 times as much as the small one Aaron want to buy 1 of each which equation can be used to find the cost a of the 2 cars

Answers

Answer:

$18

Step-by-step explanation:

small -$3

large - $15

3+15=18

Answer: The equation is $3 + ($3 x 5)

Step-by-step explanation:

You add $3 to 3 multiplied by 5 to get the cost of the second car which will then give you the cost of both cars. Then you simplify and get $3 + $15 which gives us the answer $18. So the cost of both the cars is $18.
