Answer:

Percentage of heads = 42 %

Net loss = $16

Step-by-step explanation:

Given:

Total number of tosses = 100

Number of heads come = 42

Number of tails come = 58

Find:

Percentage of heads

Net loss

Computation:

Percentage of heads = Number of heads come / Total number of tosses

Percentage of heads = 42 / 100

Percentage of heads = 42 %

Net loss = 58(1) - 42(1)

Net loss = $16

Given α and β are Supplementary. Show the necessary steps.
user100 [1]

Answer:

\alpha = 108\degree, \: \beta = 72\degree

Step-by-step explanation:

α and β are Supplementary (given)

\therefore \alpha + \beta = 180\degree.... (1)

It is given that:

\alpha= \frac{3}{2} \beta

Plugging the value of α in equation (1), we find:

\frac{3}{2} \beta + \beta = 180\degree

\therefore  \frac{3+2}{2} \beta = 180\degree

\therefore  \frac{5}{2} \beta = 180\degree

\therefore   \beta = 180\degree\times \frac{2}{5}

\therefore   \beta = 72\degree

\implies   \alpha= \frac{3}{2} \times 72\degree= 108\degree

So,

\alpha = 108\degree, \: \beta = 72\degree

A child lies on the ground and looks up at the top of a 9-ft tree nearby. The child is 13 ft away from the tree. What is the ang
choli [55]
Draw a right triangle to represent the problem.
The vertical height of the triangle is 9 ft, and it represents the tree.
The horizontal length, at the bottom of the tree is ground level and has a length of 13 ft.

Let x =  angle of elevation.

By definition,
tan x = 9/13 = 0.6923
x = arctan(0.6923) = 34.7 deg. = 35 deg (approx)

Answer: 35°

Describe a real life multiplication situation for which an estimate makes sense
Drupady [299]
If you are trying to create a garden of potted plants, you would find out how much soil each pot needs/holds and multiply that by how many pots you plan to use. then you would go to the store for potting soil, which let’s say came in smaller packs and you need to purchase multiple. use multiplication estimation to estimate how many bags you’d need.
I know this is a dumb example...sorry this is one I remember from my fourth grade math teacher ahah

kirza4 [7]
There are 30 days in the month of June. Out of the 30 days, Ava saw birds on 18.

P(bird)=18/30

We can simplify the fraction by dividing both sides by 2.

P(bird)=18/30=9/15

9/15=0.6=60%

Theres a 9/15 or 60% chance that she will see a bird on July 1st.
