My last review question before the big test! Can anyone explain this one to me? It's percentages cri

Answer:

1. a

2. b (i think)

3. b

4. a

5. d

im not sure bout all this but h ope it helps you

Step-by-step explanation:

1. solution,

length of rectangle A(l)=3.1units

breadth of rectangle A(b)=1units

now,

area of rectangle A=l×b

=3.1units×1units

=3.1 sq units

2.solution,

length of rectangle B(l)=3.1units

breadth of rectangle B (b)=0.4units

now,

area of rectangleB=l×b

=3.1units×0.4units

=1.24 sq units

3.solution,

length=3.1units

breadth=1.4units

area =lxb

=3.1units x 1.4units

=4.34units

Answer:

1) 3.1   2) 1.24  C) 4.34

Step-by-step explanation:

Area = l(w)

Area of rectangle A:

3.1 * 1 = 3.1

Area of rectangle B:

0.4 * 3.1 = 1.24

Both rectangles put together:

First, let's add 1 to 0.4... 1.4

1.4 * 3.1 = 4.34

I really, really, really hope I helped you. Good Luck :D

Answer:

8 out of 20 should be strawberry

Step-by-step explanation:

4 out of 10 were strawberry so

20 ÷ 10 = 2

2*4=8

Answer:

Check explanation

Step-by-step explanation:

There are two ways to solve this, I'm not sure which way is the correct one:

1. Solving with 3.14

V=πr²h

V=(3.14)(13)²(17)

V=(3.14)(169)(17)

V=(3.14)(2873)

V=9021.22

9021.22 rounded to the nearest hundredth is 9021.22

2. Solving with π (I used a calculator to solve with π)

V=πr²h

V=π(13)²(17)

V=π(169)(17)

V=π(2873)

V=9025.79569376

9025.79569376 rounded to the nearest hundredth is 9025.8

The question says to use 3.14 so it can be method 1, but the question also asks to round to the nearest hundredth and method 2 leads me to actually being able to round so it can be suspected that method 2 is the correct way. Whichever you think is best can be chosen and sorry if this isn't a clear answer! I hope it does help.

Answer:

V=9021.22

Step-by-step explanation:

The formula for a cylinder is πr(r)(h)

r=13

h=17

π13(13)(17)

π169(17)

π2873

π=3.14

3.14(2873)

9021.22

V=9021.22

Answer:

4 years

Step-by-step explanation:

Interest (I) = $ 100

r = 3.8 %

P = $ 700

t = ?

[tex]t = \frac{I *100}{P*r}\\\\t = \frac{100 * 100}{700 * 3.8}\\\\t = \frac{100 * 100}{70 * 38}\\\\t = 3.75[/tex]

t = 4 years

D

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

First we need to find the perimiter of a parallelogram

Side A is the slanted line,

Side B is the 2 horizontal lines.

The equation for this is 2(a+b)

Let's plug in the measurements:

2(18+27) =

2(45) =

90

So the parallelogram is 90 now we have the perimeter of the semi cirlce already which is 18

90 + 18 = 108

Hope this helps :)

Step-by-step explanation:

The area of the triangle is, 8×6/2 = 24 in²

The area of the rectangle is, 8×4=32 in²

The area of the irregular figure is,

(24+32) in²

= 56 in²

Answer:

a) y = x + 3

b) y = x + 4

Step-by-step explanation:

a)

the line is going through 3 on the y-intercept line

b)

0,4 is graphed and if there is a 0 under the x, the y is automatically the y-intercept
