Write each number in standard form.
1.
2.
3. 500 + 60 + 6
BB
Answer:
566
Step-by-step explanation:
We need to write the following number in standard form.
500 + 60 + 6
Here, the first no is 500, the second number is 60 and the other number is 6.
It can be done as follows :
500 + 60 = 560
And
560 + 6 = 566
So, the standard form is 566 inc which 6 is at one's place, another 6 at tens place and 5 at hundred places.
Dean made a triangular wall shelf.
The sides of the triangle measure
14 inches, 8 inches and 8 inches.
Is the shelf a right triangle?
Explain.
Answer:
The shelf is not a right triangle
Step-by-step explanation:
Given
[tex]Sides = 14, 8, 8[/tex]
Required
Determine if it is a right triangle
To do this, we make use of Pythagoras theorem which implies that; the square of the longest side = the sum of the square of the two other sides.
So, we have:
[tex]14^2 = 8^2 + 8^2[/tex]
Evaluate all squares
[tex]196 = 64 + 64[/tex]
[tex]196 = 128[/tex]
The above is not true because:
[tex]196 \ne 128[/tex]
Hence, the shelf is not a right triangle

Suppose an NBA basketball player shooting an uncontested 2-point shot will make the basket with probability 0.6. How- ever, if you foul t he shooter, t he shot 'vill be missed, but t'vo free thro,vs will be a'varded. Each free thro'v is an independent Bernoulli trial 'vith success probability p. Based on the expected number of points the shooter 'vill score, for what values of p may it be desirable to foul the shooter?
Answer:
0.06
Step-by-step explanation:
The computation of the value of p is shown below;
P in the case (2 points if not fouled) = 0.6
Now Expected points if not fouled is
= 0.6 × 2
= 1.2
Now Expected points from free throw is
0 × (1-p)^2 + 1 × 2p(1-p) + 2 × p^2 = 2p
As we can see that 2p would be lower tha 1.2 in order to make a foul on shooter that represent all values of p<0.06 would be considered to foul in the shooter

Taft Middle School is painting a circle on their playground with a radius of 9 feet. What will be the total
area of the circle, in square feet?
Use T = 3.14, and round your answer to the nearest hundredth.
Answer:
Area of a circle = PI * radius^2
Area = 3.14 * 9^2
Area = 3.14 * 81
Area = 254.34 square feet

Put the following equation of a line into slope-intercept form, simplifying all fractions 4x+12y=48 (WITH A EXAMPLE) PLSS HELP I'M UNDER THE WATER
Can someone help me daughter I just wanna see who helps her
Answer:
Yes.
Step-by-step explanation:
The total amount needed is the amount per teacher x the volume of the water bottles.
16 x 9 = 144
since one gallon is 128 ounces,
144/128 = 1.125 = 1 1/8
Since 1 1/8 is less than 1 1/2, there is enough water.

help please ! solve for y and simplify the answer
Answer:
y = 11.5
Step-by-step explanation:
[tex]\frac{6}{5} = \frac{9}{y-4}[/tex]
We are solving for y. Currently, y is in the denominator. We want it in the numerator so we will multiply the whole binomial (y - 4) to both sides.
[tex](\frac{y-4}{1} )\frac{6}{5} = \frac{9}{y-4}(\frac{y -4}{1})[/tex]
On the right side, (y - 4) cancels out leaving us with 9.
On the left side, we want to distribute the 6 in the numerator across the parentheses. Also multiply the denominators together.
[tex](\frac{6y - 24}{5}) = 9[/tex]
Now we want to continue to isolate y.
Multiply both sides by 5 to get rid of the denominator.
[tex]6y - 24 = 45[/tex]
Add 24 to both sides.
[tex]6y = 69[/tex]
Divide both sides by 6.
[tex]y = 11.5[/tex]
This is your answer.
Let's check it by plugging y = 11.5 back into the original equation.
[tex]\frac{6}{5} = \frac{9}{11.5-4}[/tex]
Simplify.
[tex]\frac{6}{5} = \frac{9}{7.5}[/tex]
Divide.
[tex]1.2 = 1.2[/tex]
Your answer is correct.
Hope this helps!
Answer:
y = 11.5
Step-by-step explanation:
Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
~
First, cross-multiply. Multiply 5 and y - 4 to both sides of the equation:
[tex](y - 4) * (5) * \frac{6}{5} = \frac{9}{y - 4} * (y - 4) * (5)[/tex]
[tex]6(y - 4) = 9 * 5\\6(y - 4) = 45[/tex]
Next, isolate the variable, y. First, divide 6 from both sides of the equation:
[tex]\frac{6(y - 4)}{6} = \frac{45}{6} \\y - 4 = \frac{45}{6} \\y - 4 = 7.5\\[/tex]
Then, add 4 to both sides of the equation:
[tex]y - 4 = 7.5\\y - 4 (+4) = 7.5 (+4)\\y = 7.5 + 4\\y = 11.5[/tex]
y = 11.5 is your answer.
