Answers

Answer:

192

Step-by-step explanation:

This is because its a square and all the sides on a square are equal so it would be:

top/bottom= 8*8

left/ right= 8*8

front/ back= 8*8

all equal 64 then you do 64*64*64 to get 192!

Alaina has 7 in her bank account and earns 6 each day . joel has 48 in his banck account and earn 8 earch day in how many days will joel have as much money alaina

Answers

Answer:

I think you wrote something wrong.

Step-by-step explanation:

If Alaina has $7 in her bank account and Joel had $48 in his Joel already has more then Alaina but I will attempt to teach you how to solve these types of problems.

for this example I'm giving Alaina 79 dollars.

First we know were starting with 79 dollars and increasing 6 dollars each day so the equation for this is; y = 6x + 79 that is Alaina's equation.

For Joel our equation will be; y = 8x + 48.

Since they already have 79 and 48 dollars in their bank we put those as our B in the equation cause they are our y-intercepts. (Y = mx + b) Next we know their increasing by 6 and 8 dollars a day so we make those our m. Once we have these equations we can plot them and see where the lines meet. (thats our answer) I plotted them on desmos graphing calculator.

They crossed at (15.5, 172) Which means it will take 16 days for Joel to catch up they will both have 172 dollars in the bank account on the 16th day.

Hope this helps!

What is the value of x in the diagram?
A right angled triangle with base 2x+2, altitude x and hypotenuse 2x+3.

Answers

Answer:

x = 5

Step-by-step explanation:

x² + (2x+2)² = (2x+3)²

x² + 4x² + 8x + 4 = 4x² + 12x + 9

x² - 4x - 5 = 0

(x - 5)(x + 1) = 0

x = -1  This can be discounted as the answer because you cannot have a negative length

answer: x = 5

This formula is used to calculate the area of a circle using the diameter:

A= 1/4πd².

Rearrange the formula to calculate the diameter of a circle.
d = _____

Answers

Answer:

d= 2√a/π

     

To calculate the diameter, rewrite the formula to isolate D

Because a negative diameter doesn’t make sense, eliminate the negative answer from the solution

Simplify further to get the solution

The formula to calculate the diameter of the circle is d = 2 √( A/π )

where d = diameter of the circle

A = area of the circle

What is a Circle?

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The perimeter of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle

Given data ,

Let the radius of the circle be = r

So , the diameter of the circle = 2r

Now , the area of the circle = πr²

Substituting the value for r , we get

Area of the circle = ( 1/4 ) πd²

So , A = ( 1/4 ) πd²

Now , solving the equation for diameter of circle d , we get

Multiply by 4 on both sides of the equation , we get

πd² = 4A

Divide by π on both sides of the equation , we get

d² = 4A/π

Taking square roots on both sides of the equation , we get

d = 2 √A/π

Therefore , the value of d is 2 √A/π

Hence ,

The formula to calculate the diameter of the circle is d = 2 √( A/π )

where d = diameter of the circle

A = area of the circle

​

Answers

Answer:

(72.5,87.5)

Step-by-step explanation:

The interval of times that represents the middle 99.7% of his finishing times in the 400 meter race is; (73.5, 87.5)

What is the interval from empirical rule?

We are given;

Mean; E(X) = μ = 80 seconds

Standard Deviation; σ = 2.5

From the empirical rule, the probability of obtaining values within one deviation from the mean is 0.68; within two deviations is 0.95 and within 3 deviations from the mean is 0.997.

We have 99.7 % of the values within 3 deviations from the mean in our question and so the intervals are;

μ - 3σ = 80 - 3(2.5) = 73.5

μ + 3σ = 80 + 3(2.5) = 87.5

The area of a circle is 201 square meters. Find
the radius.

Answers

Answer:

8.0meters

Step-by-step explanation:

Given data

Area of cirlce= 201 square meters

The expression for the area is

A=πr^2

Substitute our area

201= 3.14*r^2

r^2= 201/3.14

r^2= 64.01

square both sides

r= √64.01

r= 8.0 meters

Hence the radius is 8.0meters

Round yo The nearest ten 834,692.Help me please!! Music and the BrainFrom the beginning of recorded history, music has been created and enjoyed by people. Even early man carved flutes from bones. Thomas Jefferson was known to play his violin to help him formulate the most effective word choices as he wrote the Declaration of Independence. Albert Einstein, considered one of the most intelligent men who ever lived, also played the violin. He was said to have figured out his most challenging mathematical formulas by playing his violin. Today scientists are discovering that the study of music, playing an instrument, or participating through singing can actually help develop our brains. No wonder Einstein and Jefferson, among many, found music helpful in problem solving.There was a time in Americas history when music was a centerpiece of family life. There were no televisions, radios, or other forms of electronic entertainment. Social life often involved someone playing the piano or another instrument while guests sang along or listened for enjoyment. Therefore, if parents could afford the opportunity, their children were encouraged to learn how to play an instrument. Taking music lessons did not mean a child was expected to become a professional musician. However, it usually meant the kids learned the daily discipline of practice.Recent brain research has shown some surprising benefits as a result of formal musical training. Learning to play a musical instrument appears to develop parts of the brain that can even influence academic results. The studies indicate that the earlier a child begins training, the more benefits there are. One such study showed that children who began musical studies before the age of seven had a more developed brain in the region where language production and auditory processing take place. Scientists believe there is mounting evidence to show that early musical training can improve brain function.A research team from Northwestern University observed that to achieve the positive brain development from musical training, music students had to be active participants. There were differences found between the kids who attended a more passive music appreciation class, and the ones who learned to play instruments. It was the active production of music that rewired the brain. Using electrodes on the students heads, scientists were able to see how actively the brain responded when students generated music.Neuroscientists have suggested that playing an instrument, especially at an early age, can improve how the brain interprets sensory information. Music (singing or playing an instrument) also positively affects memory. Apparently, music activates both the right and left sides of the brain simultaneously and this activity increases efficiency in processing information. In one study, researchers found the areas of the brain that affect language skill and executive function were more developed in musically trained students. The executive function is the planning center of your brain, where you figure out what must get done, and how to do it in the time that exists.A special community music program in a low-income area of Los Angeles showed a higher success rate of students going on to college than students in the area who did not participate in this music education. A team of researchers was asked to offer scientific evidence for this compelling distinction. The study concluded that there were significant improvements in reading scores for the children who attended music classes regularly and were actively engaged for a period of two years, compared to those who did not participate.What tone does the statement "The executive function is the planning center of your brain" give in Paragraph 5?an insistent tonea critical tonean instructive tonea forceful tone How would The yellow wallpaper change if he were to order from a different characters perspective? in dogs, being clumsy (C) is dominant to being cool (c) and being dazzling (D) is dominant to being docile (d) Personality may be influenced by:birth orderb. characteristics of the parentsa.c. both a and bd. neither a nor bPlease select the best answer from the choices provided A painter took 15 hours to paint 12 rooms in a building.
