Can someone please help me with this

Mathematics
1 answer:
julsineya [31]3 years ago
8 0

Answer:

Step-by-step explanation:

5- There are 2 right-angled triangles and 1 equilateral triangle or you can just say triangles

6- area for a triangle is a=bh(1/2)

so 4×3=12(1/2)=6

and 4×3=12(1/2)=6

In both triangles, they're a=6

7- 4×6=24(1/2)=12

the top flag is a=12

8-12+6+6=24

9- the rectangular flag has an area of 24 since a=bh and the added areas of the triangles are 24. I conclude that these are two ways of finding the area of this rectangular flag.

hope this helps : )

Employees were asked how many times per week they exercised. The frequency table shows the results of the survey.
wlad13 [49]

Answer:

See explanation

Step-by-step explanation:

Given the frequency table

\begin {array}{cccccccccc}\text{Number}&0&1&2&3&4&5&6&7&8\\ \\\text{Frequency}&5&10&2&9&33&12&15&3&1\end{array}

a) The total sum is

5+10+2+9+33+12+15+3+1=90

Create a probability distribution table

\begin {array}{cccccccccc}\text{Number}&0&1&2&3&4&5&6&7&8\\ \\\text{Probability}&\dfrac{5}{90}&\dfrac{10}{90}&\dfrac{2}{90}&\dfrac{9}{90}&\dfrac{33}{90}&\dfrac{12}{90}&\dfrac{15}{90}&\dfrac{3}{90}&\dfrac{1}{90}\end{array}

b) The probability

P(x

c) The probability

P(x=6)=\dfrac{15}{90}=\dfrac{1}{6}

d) The probability

P(x\ge 5)=P(x=5)+P(x=6)+P(x=7)+P(x=8)=\dfrac{12}{90}+\dfrac{15}{90}+\dfrac{3}{90}+\dfrac{1}{90}=\dfrac{31}{90}

The national debt in 2013 was $16,755,133,009,522. What is the smallest power of 10 that will exceed this number.​
Artemon [7]

Answer:

10^{14}

Step-by-step explanation:

In scientific notation, the national debt in 2013 was approximately

1.67 \times 10^{13}

You can see this by taking the decimal point between the 1 and 6 and moving it 13 places to the right.

The smallest power of 10 that will be larger than this number is  10^{14}.

Find the distance between the two numbers on the number line<br> -3.4, 2.8
nignag [31]

Answer:

A simple way to calculate the distance between numbers on a number line is to count every number between them. A faster way is to find the distance by taking the absolute value of the difference of those numbers. For example, the absolute values of 4 and -4, or |4| and |-4|, are both 4.
