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.

Step-by-step explanation:

48 degrees per 12 hours = 48/12 degrees per hour = 4 degrees per hour

The event is independent event in nature .

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.

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 .

Answer:

-4

Step-by-step explanation:

According to the rules of the distributive property, you have to multiply the term outside of the parentheses with the terms inside the parentheses first.

1. 2(-5)=-10    

2. 2(3)=6

The terms that we have are now -10 and 6. Add them together to get the final answer.

-10+6=-4

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.

Step-by-step explanation:

i have this question answer on my notebook good thing your lucky :D

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.

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.

Answer:

1 Meter (m) is equal to 0.001 kilometer (km). To convert meters to km, multiply the meter value by 0.001 or divide by 1000. For example, to convert 100 m to km, multiply 100 by 0.001, that makes 0.1 km is 100m .

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 value of tan∠A form the right angled triangle ABC is 1.

Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.

Given that △ABC be a right triangle with m∠C = 90°. Also, tan∠B = 1. Hence:

tan∠A = (tan∠B)⁻¹ = 1

The value of tan∠A form the right angled triangle ABC is 1.
