Answers

Answer 1

Answer:

[tex]A = 336[/tex] [tex]m^{2}[/tex]

Step-by-step explanation:

Using the formulas

[tex]A=\sqrt{s(s-a)(s-b)(s-c)}[/tex]

[tex]s=\frac{a+b+c}{2}[/tex]

Solving for [tex]A[/tex]

[tex]A=\frac{1}{4} \sqrt{-a^{4}+2(ab)^{2} +2(ac)^{2} -b^{4} +2(bc)^{2}-c^{4} }[/tex]

[tex]=\frac{1}{4} *\sqrt{-42^{4} +2*(42*34)^{2}+2*(42*20)^{2} -34^{4} +2*(34*20)^{2} -20^{4} }[/tex]

Write the equation of the line perpendicular to y = 5x + 1 that passes through the point ( – 5,1).
Type an equation using slope-intercept form or using the given point in point-slope form.
(Use integers or simplified fractions for any numbers in the equation.)

Answers

Answer:

y = -1/5x

Step-by-step explanation:

Using the 'y=mx+c' form for the equation:

Find the slope (m):

Since the product of both slopes should be -1 (if they are perpendicular),

s₁s₂  = -1

5*s₂ = -1

s₂ = -1/5x

Hence, the slope (m) is -1/5x.

Substituting the slope value into 'y=mx+c':

y = -1/5x+c -----(1)

Substituting the point (-5,1) into the equation (1):

1 = -1/5 * (-5) + c

1 = 1 + c

c = 0

Substitiuting 'c=0' into 'y = -1/5x+c':

y = -1/5x

Hence,

y = -1/5x

Sarah's Volleyball team won 12 out of 14 games if this rate continues, how many games will they win if they play a total of 21 games

Answers

Answer:

18 games

Step-by-step explanation:

If Sarah's Volleyball team won 12 out of 14 games, then their win rate is 12/14. You can simplify this fraction down to 6/7 to make it easier, but you don't have to.

If they keep the same rate of 6/7 (6 wins for every 7 games they win), you multiply the rate by the total games to get the number of wins. wins/games (rate) x total games = total wins, so 6/7 x 21 = 18.

a line containing the points (4, y) and (-3, 2) has a slope of 3/2.

Answers

Answer:

y=14.5

Step-by-step explanation:

A slope of 3/2 means that for every unit it moves to the right, it will move 1.5 units up. The x of 4 is 7 more than the -3 of our other point. 7*1.5=12.5, and 12.5+2=14.5.

A chemist mixes 100 milliliters of a solution that is 75% acid with 25 milliliters of a solution that is 35% acid.
Answer the questions below. Do not do any rounding.
(a) How many milliliters of acid are in the resulting mixture?
(b) What percentage of the resulting mixture is acid?


Answers

Answer:

85% acid

Step-by-step explanation:

The amount of acid is 83.75 milliliters

The percentage of the resulting mixture of acid is 67%

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

A chemist mixes 100 milliliters of a solution that is 75% acid with 25 milliliters of a solution that is 35% acid.

This means,

75% of 100 milliliters = 75/100 x 100 = 75 milliliters

35% of 25 milliliters = 35/100 x 25 = 8.75 milliliters

Now,

The amount of acid is (75 + 8.75) = 83.75 milliliters

The percentage of the resulting mixture of acid.

= 83.75 / (100 + 25) x 100

= 83.75/125 x 100

= 67%

Thus,

The amount of acid is 83.75 milliliters

The percentage of the resulting mixture of acid is 67%

Please I need help I wasnt at school today What is a stomata? Thank you! Tony and Suzie are ready to expand Great Adventures even further in 2022. Tony believes that many groups in the community (for example, Boy Scouts, church groups, civic groups, and local businesses) would like to hold one-day outings for their members. Groups would engage in outdoor activities such as rock climbing, fishing, capture the flag, paintball, treasure hunts, scavenger hunts, nature hikes, and so on. The purpose of these one-day events would be for each member of the group to learn the importance of TEAM (Together Everyone Achieves More).Tony knows that most people are not familiar with these types of activities, so to encourage business he allows groups to participate in the event before paying. He offers a 4% quick-payment discount to those that pay within 10 days after the event. He also guarantees that at least eight hours of outdoor activities will be provided or the customer will receive a 20% discount.
