yall pls help meeeee (brainliest btw)!!!!!

Colossal Elementary School had a mother/daughter painting weekend. On Saturday, eight mothers worked with 12 daughters to paint 220square feet of a large mural on a wall in the gymnasium. The next day, six moms worked with eight daughters to paint another 152square feet of the mural in the gym. Write and solve a system of equations to find how many square feet each mom painted and how many square feet each daughter painted. Assume all moms painted at the same rate and all daughters painted at the same rate.

Answers

Answer 1
Answer:

Let m be the amount each mom can paint and d be the amount each daughter can paint.

On the first day, 8 mothers were painting so the mothers painted 8m square feet. 12 daughters also painted so the daughters painted 12d square feet. The total amount painted on the first day is then 8m+12d square feet. Since 220 square feet was painted on the first day, then 8m+12d=220.  Dividing both sides by 4 gives a simplified equation of 2m+3d=55.

On the second day, 6 mothers were painting so the mothers painted 6m square feet. 8 daughters also painted so the daughters painted 8d square feet. The total amount painted on the second day is then 6m+8d square feet. Since 152 square feet was painted on the second day, then 6m+8d=152

Multiply the first equation by -3 and then add it to the second equation to eliminate m and solve for d:

d=13

2m+3d=55

2m+3(13)=55

2m+39=55

2m=16

m=8

Therefore each mom painted 8 square feet and each daughter painted 13 square feet.

Identify the relationship between angles x and y

Answers

Answer:

Therefore the two angles labelled x are equal. Also, the two angles labelled y are equal. We know that x, y and z together add up to 180 degrees, because these together is just the angle around the straight line. So the three angles in the triangle must add up to 180 degrees.

Answer:

6 bowls of ramen

Step-by-step explanation:

because $1.50 * 4 is 6

49.50 - 6 = 43.50

43.50/7.25 = 6

Answer:

a)2(1.50)+7.25x=47.50

b) about 6 bowls.

Step-by-step explanation:

Right off the bat, we know that each drink is $1.50. So buying two would be $3 so far. Subtract $3 from $49.50. Getting $47.50. Now we know the drinks so we must divide 47.50 by 7.25, equalling 6.5 and so on. To round it we can say 6 bowls.

can someone explain to me how you figure out if a triangle is obtuse, acute or a right angle? i will give 20 points

Answers

Answer:

Right angle is 90 degrees, belowe 90 degrees is acute, and above 90 degrees is obtuse

Step-by-step explanation:

Right angle = 90degrees

Acute angle = <90degrees

Obtuse angle = >90degrees

Answer:

To figure out if a triangle is obtuse, There would be one angle that is over 90 degrees. If it is an acute triangle, all of the angles would be smaller than 90 degrees. If it is a right triangle, there would be one angle that is 90 degrees and the other 2 angles would be acute.

PLEASEE HELP I NEED HELP PROBLEM
Melinda takes readings of the depth of water in a
pond every day for 1 week. Here are her results in
meters:
6.5, 6.8, 7.2, 6.8, 6.6, 6.3, 6.4
What are the mean, median, and mode water levels
for the week, rounded to the nearest tenth?
Answer with supporting work:

Answers

Answer:

a) The Mean of the water levels for the week (μ) = 6.657

b) The Median of the water levels for the week = 6.6

c) Mode = 6.8

Step-by-step explanation:

Step(i):-

Given that the data per one week

6.5,  6.8 , 7.2  ,6.8  ,6.6  ,6.3 , 6.4

we have to find the mean of the given data

Solution:-

Mean = ∑x /n

[tex]Mean = \frac{6.5+6.8+7.2+6.8+6.6+6.3+6.4}{7}[/tex]

Mean = [tex]\frac{46.6}{7}[/tex]

Mean(μ) = 6.657

The Mean of the water levels for the week (μ) = 6.657

Step(ii):-

Given that the data per one week

6.5,  6.8 , 7.2  ,6.8  ,6.6  ,6.3 , 6.4

we have to find the Median of the given data

A median is the center value of a  given  data when arranged in an order

6.3  6.4  6.5 6.6  6.8  6.8 7.2

The Median = middle of the given data

The Median = 6.6

Step(iii):-

Given that the data per one week

6.5,  6.8 , 7.2  ,6.8  ,6.6  ,6.3 , 6.4

we have to find the Mode of the given data

Mode = Value repeated the most number of times

The value 6.8 repeated two times

Mode = 6.8

The event is independent event in nature .

What is independent events ?

Independent events are those events whose occurrence is not dependent on any other event. For example, if we flip a coin in the air and get the outcome as Head, then again if we flip the coin but this time we get the outcome as Tail.

What is dependent events?

Two events are dependent when the outcome of the first event influences the outcome of the second event. The probability of two dependent events is the product of the probability of X and the probability of Y AFTER X occurs.

According to the question

You pick a red jolly rancher candy from a jar, give it to a friend, then pick another red jolly rancher candy.

You pick a red jolly rancher candy from a jar, give it to a friend is independent event

and the second event pick another red jolly rancher candy. is completely independent event

and both of them are not dependent on each other

So this event is independent because two events happen is not depend on each other .

Hence, The event is independent event in nature .
