Find the area of all three of them then add them together.
TRIANGLE:
A=1/2*b*h
A=1/2*8*h
The height is not given to us, so we need to make a separate triangle to figure it out. (Work is in picture 1)
A=1/2*8*6.9
A=27.7
SQUARE:
A=s^2
A=8^2
A=64
POLYGON:
Area=1/2*a*p
The polygon has 5 sides.
The perimeter will be 8*5, or 40.
The apothem is found in the next snapshot.
A=1/2*1.9*40
A=38
TOTAL AREA:
38+22.7+64=124.7

Two lengths of a triangle are shown.
Solnce55 [7]

Answer:

11 ft

Step-by-step explanation:

Given the two lengths of a triangle as

AB = 6ft

AC = 6ft

This is an isosceles triangle because only 2 sides are equal.

In an isosceles triangle, the sum of 2 (sides) lengths must be greater than the other length.

Therefore, let's assume the following:

i) AC + AB > BC

6 + 6 > BC

12 > BC (BC is less than 12)

BC < 12

ii) BC + AC > AB

BC + 6 > 6

BC > 6 - 6

BC > 0

Therefore the range of values for BC =

0 < BC < 12

Since BC must be bigger than one of the lengths and it must also be less than the sum of the 2 sides. The length of BC could be 11 because it is less than (6+6) 12 and greater than 6.

Oumou is buying tile for her kitchen. The area of Oumou’s rectangular kitchen, in square feet, can be found by using the express
SOVA2 [1]
Explanation: “The distributive property is where a number or value is distributed into a whole equation. Based on the work below as you can see I “distributed” 5 to (3m+4n) meaning I multiplied 5&3m and 5&4n, when I multiply 5&3 that give me 15, and when I multiply 5&4 that gives me 20. So when finally simplified my new equation is 15m+20n”

Make sure when you is the distributive property that you always add the variables because it will be wrong.

Activity paper to answer
PIT_PIT [208]

Answer:

1.

a) 5cm

b) 16cm

c) 25cm

d) 124cm

2.

a) 4m

b) 6m

c) 10m

d) 26m

3.

a) 2km

b) 4km

c) 11km

d) 28km

Step-by-step explanation:

When you have a number and it tells you to round it to the nearest cm (m, km etc.), it means you just have to make it a whole number (integer) instead of a decimal by rounding it up or down.

To tell whether you round up or down, you look at the number after the decimal place and if it is under 5, you round down but if it is 5-9 you round up.

For example,

If we had 20.3 (not one of the questions) you would round it down to 20 because the 3 after the decimal place is smaller than 5.

However, if we had 24.7 you would have to round it up because the 7 is from 5-9.

Hope this helps :)

Evaluate. Write your answer as an integer or as a decimal rounded to the nearest hundredth. tan 32° = _____
Advocard [28]

Answer

0.63

Explanation:

Given the expression

tan 32

Using Calculator

tan 32 = 0.6248

Converting to nearest hunderdth

tan 32 = 0.63

hence tan 32 to the nearest hunderdth is 0.63
