50 magazines
because ratio is division and 225/5 is 25 and you multiply the 2 by 25 and you get 50
There are 64 magazines in the library.
What is mean by Ratio?A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.
We have to given that;
The ratio of books to magazines in the children's section at the library is 5: 2.
Let number of books = 5x
And, Number of magazines = 2x
Here, There are 225 books in the library.
Hence, We can formulate;
⇒ 5x + 2x = 225
⇒ 7x = 225
⇒ x = 32
Hence, Number of magazines = 2x
= 2 × 32
= 64

-(1+7x)-6(-7-x)=36 what is x equal to
Answer:
x = 5
Step-by-step explanation:
Step 1: Write equation
-(1 + 7x) - 6(-7 - x) = 36
Step 2: Solve for x
Distribute: -1 - 7x + 42 + 6x = 36Combine like terms: -x + 41 = 36Subtract 41 on both sides: -x = -5Divide both sides: x = 5Step 3: Check
Plug in x to verify it's a solution.
-(1 + 7(5)) - 6(-7 - 5) = 36
-(1 + 35) - 6(-12) = 36
-(36) + 72 = 36
-36 + 72 = 36
36 = 36

Answer:
m∠PQR = 133
Step-by-step explanation:
∠PQR and ∠RQS are supplementary angles, meaning they have a sum of 180°.
3x - 5 + x + 1 = 180
4x - 4 = 180
4x = 184
x = 46
Now we simply substitute 46 in for x:
3(46) - 5 = 133

The distance, D, travelled by a particle is directly proportional to the square of the time, t, taken. When t = 40, D = 30. find a formula for D in terms of t. Calculate the value of D when t = 64
Answer:
The formula for D in terms of t is D=0.01875t²
The value of D is 76.8
Step-by-step explanation:
See above for an image
Hope I helped!
After calculating by definition of proportionality, the value of D is 76.8
What is Proportional?Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
Given that;
The distance, D, travelled by a particle is directly proportional to the square of the time, t.
So, We can defined as;
⇒ D = k × t²
Where, 'k' is constant of proportion.
Here, When t = 40, D = 30,
⇒ D = k × t²
⇒ 30 = k × 40²
⇒ 30 = k × 1600
⇒ k = 30 / 1600
⇒ k = 3/160
So, When t = 64, the value of D is,
⇒ D = 3/160 × 64²
⇒ D = 76.8

60% of a firm's employees are men. Suppose four of the firm's employees are selected. a. What is the random variable we can consider here? b. What is probability of finding three men and one woman? c. What is the answer for part if 75% of employees were men?
Answer:
60% of the employees are men.
Then the 40% left must be women.
4 of them are selected.
a) What is the random variable we can consider here?
A random variable is a variable that can have different outcomes or values, in other words, it is a stochastic variable.
We have a selection of 4 employees at random, then we can define the variable X, that represents (for each employee) the possibility of being man or woman.
b) Probability of 3 men and 1 woman.
Suppose that the selection is in the order:
man-man-man-woman.
We have:
0.6 tree times.
0.4 one time.
P = 0.6^3*0.4
But this is for the case where the woman is in the last selection, it can be in the first, second and third, then we have 4 permutations, the actual probability is:
P = 4*( 0.6^3*0.4) = 0.3456.
c) If now we have tat 75% are men, then 25% are women.
Now we can do the same as before, but now the probability for a man is 0.75 and for a woman is 0.25, then the previous equation is now:
P = 4*(0.75^3*0.25) = 0.421875
(a) The random variable will be "Men percentage".
(b) The probability of finding 3 men and one woman be "0.3456".
(c) The probability be "0.4219".
Probability(a) A random variable represents a variable which might have several occurrences as well as quantities; it is indeed a stochastic quantity.
If we choose four workers at random, users may create the variable X, which reflects the potential of someone being a male or even a woman.
(b) The probability be:
→ P(3 men and women) = [tex]4C_3[/tex] (0.6)³ (1 - 0.6)¹
= 0.3456
(c) The probability be:
→ P(3 men and women) = [tex]4C_3[/tex] (0.75)³ (1 - 0.75)¹
= 0.4219
Thus the response above is correct.

A right triangle with angle measures of 45, 45, 90 degrees undergoes a reflection, rotation, and translation. Determine whether the angle measure of the image of the triangle are 45, 45 and 90 degrees after each transformation. Choose yes or no.
Answer:
Reflection - Yes
Rotation - Yes
Translation - Yes
Step-by-step explanation:
After all 3 different transformations, the angle measures of the triangle will stay the same, at 45, 45, and 90 degrees.
This is because these 3 transformations do not change the shape of the triangle. They only change the orientation and placement of the triangle.
So, the angle measures will still be 45, 45, and 90 degrees after each transformation.
