For the right triangles below, find the values of the side lengths d and b.
Write answers in simplified radical form if necessary.
Answers
Answer:
d = 2√2b = 5√3Step-by-step explanation:
In these special right triangles, the sides have length ratios ...
45-45-90: 1 : 1 : √2
30-60-90: 1 : √3 : 2
This tells us ...
d×√2 = 4 . . . . . . . . . . relationship between the side and the hypotenuse
d = 4/√2 = 2√2
__
b = 5√3 . . . . relationship between the short side and long side

Increase 268 by
by 75%
Answers
Answer:
268 increased by 75% of its value = 469
Step-by-step explanation:
hope this helps :))
The number when 268 is increased by 75% will be 469.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
Let 'n' be the increased number. Then the equation is given as,
75% = [(n - 268) / 268] x 100
Simplify the equation, then we have
0.75 = (n - 268) / 268
n - 268 = 201
n = 201 + 268
n = 469
The number when 268 is increased by 75% will be 469.

If you spin the spinner 6 times, what is the best prediction possible for the number of times it will land on green or yellow?
Answers
Answer:
2:6
Step-by-step explanation:
You spin it 6 times, you have a chance of getting two options
^^ this is a guess but it seems pretty reasonable
The best prediction possible for the number of times the spinner will land on yellow if it is spun 6 times is 1.
How to solve probability?If the spinner has 12 equal parts and 2 of them are yellow, then the probability of the spinner landing on yellow is 2/12, or 1/6. This means that out of every 6 spins, we can expect the spinner to land on yellow once.
To find the best prediction for the number of times the spinner will land on yellow if it is spun 6 times, we can use the idea of expected value. The expected value of an event is the average value we would expect to see if the event were repeated many times.
Expected value = Probability of yellow x Number of spins
Expected value = (1/6) x 6
Expected value = 1
This means that out of 6 spins, we can expect the spinner to land on yellow approximately 1 times on average.

Step-by-step explanation:
The equation for finding the volume of a cube is
length x width x height
so you need to multiply 5/8 by 1/2.
This will give you 5/16.
Now multiply 5/16 by 3/4.
This will give you 15/64 , which in decimal form will be your answer 0.23

Like terms are those terms that are having the same variables and order. The simplified form of the given equation 7z+2=8+2z+1z is 4z=6.
What are Like terms?Like terms are those terms that are having the same variables, also the variables are of the same order as well.
for example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.
The given equation to us is 7z+2=8+2z+1z, simplifying the equation we will get,
[tex]7z + 2 = 8 + 2z + 1z\\\\\text{Bring the like terms on the same side of the equation}\\\\7z -2z-1z = 8 -2\\\\7z-3z=6\\\\4z = 6[/tex]

What is the multiplicative rate of change of the function? One-third Two-thirds 2 9.
Answers
The multiplicative rate of change of the function will be [tex]\frac{2}{3}[/tex].
What is the multiplicative rate?It is an arithmetical operation that calculates the product of two values, first described in terms of repeated addition.
When the value of x is changed from 1 to 2, the value of y is changed from 6 to 4.
The multiplicative rate of change of the function will be
[tex]\frac{4}{6} = \frac{2}{3}[/tex]
When the value of x is changed from 2 to 3, the value of y is changed from 4 to [tex]\frac{8}{3}[/tex].
The multiplicative rate of change
[tex]\frac{\frac{8}{4} }{4} = \frac{2}{3}[/tex]
When the value of x is changed from 3 to 4, the value of y is changed from [tex]\frac{8}{13}[/tex] to [tex]\frac{16}{9}[/tex].
Hence the multiplicative rate of change of the function will be [tex]\frac{2}{3}[/tex].
