Find the area of each composite figure. Use 3.14 for π. Round to the nearest tenth if necessary. Whats the correct label?
Step-by-step explanation:
Square= bh
Square= 2×2=
half-circle = 1/2Pi*r×r
half-circle 2 = 1/2Pi*r×r
We would put 1/2 for the half-circle because its half of a circle. And we square it because where finding area. The middle is square, and the two up top is half a circle. Hope that helps :D
PLEASE HELP ME!!
What is the surface area of the figure?
9514 1404 393
Answer:
B. 24 cm²
Step-by-step explanation:
The formula for the area of a triangle is ...
A = 1/2bh
Here, you have a base of 4 cm and a height of 3 cm, so the area is ...
A = (1/2)(4 cm)(3 cm) = 6 cm²
__
The rectangle on the right is 3+1.5 = 4.5 cm high, and 8 -4 = 4 cm wide. Its area is ...
A = WH
A = (4 cm)(4.5 cm) = 18 cm²
The total area is the sum of the areas of the parts:
total area = triangle area + rectangle area
total area = 6 cm² + 18 cm² = 24 cm²

Answer:
4 crickets
Step-by-step explanation:
On the first day, the lizard ate 50% of the 10 crickets it was given. 50% of 10 is 5 (10 times 0.5), so five crickets remain. The next day, the lizard ate 20% of the 5 remaining crickets. 20% of 5 is 1 (5 times 0.2), and 5-1=4, so 4 crickets are left.

What is a function? What is equation modelling? What is a mathematical equation and expression?In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the functionEquation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given are the equations -
1. 2a=4.6
2. b+2=4.6
3. c÷2=4.6
4. d−2=4.6
5. e+38=2
6. 18f=3
7. g÷85=1
We have -
[1] -
2a = 4.6
a = 2.3
[2] -
b + 2 = 4.6
b = 2.6
[3] -
c ÷ 2 = 4.6
c x 1/2 = 4.6
c = 4.6 x 2
c = 9.2
[4] -
d − 2 = 4.6
d = 6.6
[5] -
e + 38 = 2
e = - 36
[6] -
18f = 3
f = 3/18
f = 1/6
[7] -
g ÷ 85 = 1
g x 1/85 = 1
g = 85
Therefore, all the parts are solved above.

Answer:
I believe that it would be better to use the second scale, or 1ft to 500ft.
Step-by-step explanation:
If you used the first scale(1in to 10ft) then you would have a 75in model, or 6.25ft, this would be to big to display on your desk. If you used the second then your model would be about 1.5in which all though is small it would be better for display.
Answer:
1 inch
Step-by-step explanation:
1 foot = 500 feet
1 inch = 10 feet
^ if you do 12 x 10 it equals 120, which is less than 1 foot = 500.
But, if you want it a big it would be 1 foot = 500.

Answer:
18
Step-by-step explanation:
All I did was count the lines on the coordinate grid between -12 and 6. I was counting by 2's because the grid itself is counting by 2's
========================================================
Explanation:
If you start at 6, and count the number of spaces to get to -12, you should count out 18 spaces.
Or you could start at -12 and move to 6 to move 18 spaces to the right. Keep in mind each tickmark represents 2 spaces.
--------------
You could also think of it like this:
Place point A at -12, B at 0, C at 6
The distance from A to B is 12 units. The distance from B to C is 6 units. In total we have AB+BC = 12+6 = 18 units from A to C.
----------------
Or you could use absolute value and subtraction
Let P = -12 and Q = 6
We could say
|P - Q| = |-12-6| = |-18| = 18
or
|Q - P| = |6 - (-12)| = |6 + 12| = |18| = 18
The order of subtraction doesn't matter as long as you apply absolute value. Absolute value represents distance from 0 on a number line, so absolute value is never negative.
