Step-by-step explanation:
2/9 of the 45 marbles must be red.
2/9 * 45 = 10
Answer:
10
Step-by-step explanation:
let's make the number of red marbles x
so probability of getting red marbles is x/45
so;.
[tex] \frac{x}{45} = \frac{2}{9} [/tex]
[tex] 45 \times \frac{x}{45} = \frac{2}{9} \times 45[/tex]
[tex]x = \frac{2}{9} \times 45[/tex]
[tex]x = 10[/tex]
so the number of red marbles is 10

Find the lowest common denominator of the following fractions.5/n-2 and n+2/ n^2-4 n - 2 n2 - 4 (n - 2)(n2 - 4)
Answers
Answer:
(n-2)(n+2)
Step-by-step explanation:
The denominator of the second fraction is the difference of squares, so can be factored using the formula for that.
(n^2 -4) = (n -2)(n +2)
Now, you will note that the second fraction has a numerator that is equal to one of the factors in the denominator. In other words, the whole fraction can be simplified to ...
(n +2)/((n +2)(n -2)) = 1/(n -2) . . . . with the restriction n≠-2
This reduced form of the fraction has the same denominator as the first fraction, so you can say that the lowest common denominator is that: (n -2).
If there is some reason you don't want to reduce the second fraction, the lowest common denominator will be (n -2)(n +2).

Gino paid $3.23 for two tubes of toothpaste. He paid the regular price of $1.79 for one tube. However, he bough the other one for less because he used a discount coupon. How much was the coupon worth?
Answers
Answer:
Step-by-step explanation:
Cost of two tubes = $ 3.23
Regular price of one tube = $ 1.79
so, the cost of other tube = 3.23 - 1.79 = $ 1.44
Discount = 1.79 - 1.44 = $ 0.35
A recipe requires 2/3 of a cup of yogurt. Rachel has 1/2 of a cup of yogurt from a snack pack. How much of the recipe can Rachel make?
Answers
Answer:
Rachel can make 3/6 out of 4/6 of the recipe.
Step-by-step explanation:
The amount of the recipe that Rachel can make is 1/2.
How much of the recipe can Rachel make?To determine how much of the recipe Rachel can make with 1/2 cup of yogurt, we need to find the fraction of the recipe that corresponds to that amount.
The recipe calls for 2/3 of a cup of yogurt, and Rachel has 1/2 cup. To compare these two amounts, we need to find a common denominator.
The least common denominator (LCD) for 3 and 2 is 6. To convert the fractions to have a denominator of 6, we multiply the numerator and denominator of 2/3 by 2, and the numerator and denominator of 1/2 by 3:
2/3 x 2/2 = 4/6
1/2 x 3/3 = 3/6
Now, we can see that Rachel has 3/6 cup of yogurt, which is equivalent to 1/2 cup. This means she has exactly half of the required amount.
Therefore, Rachel can make 1/2 of the recipe with the amount of yogurt she has.

Given cos = 7/25, where is an angle in standard position terminating in
quadrant IV, what is the value of tan ?
Answers
Answer:
tanΘ = - [tex]\frac{24}{7}[/tex]
Step-by-step explanation:
Given
cosΘ = [tex]\frac{7}{25}[/tex] = [tex]\frac{adjacent}{hypotenuse}[/tex]
The right triangle has sides 7, 24, 25 ← Pythagorean triplet
with adjacent = 7 and opposite = 24
Since position is in fourth quadrant then tanΘ < 0 , thus
tanΘ = - [tex]\frac{24}{7}[/tex]
Explain why you cannot use the Distributive Property to evaluate an expression in the form of sin(a + b). Please illustrate with an example along with your explanation.
Answers
Answer:
The distributive property is to multiply the outside of a parenthesis by each term inside, for example:
[tex]x(y+z)=xy+xz[/tex]
this cannot be done with the trigonometric functions such as the sine.
An example of this:
let's prove that we don't get the correct result using the distributive property in the following expression:
[tex]sin (\pi+\pi/2)[/tex] ≠ [tex]sin(\pi)+sin(\pi/2)[/tex]
We add the elements in the parentheses on the left side:
[tex]sin(3\pi/2)[/tex] ≠ [tex]sin(\pi)+sin(\pi/2)[/tex]
this are known values of the sine function:
[tex]sin(3\pi/2)=-1[/tex]
[tex]sin(\pi)=0[/tex]
[tex]sin(\pi/2)=1[/tex]
substituting these values we will get that:
-1 ≠ 0 +1
-1 ≠ 1
Thus we notice that we don't get the correct result using the distributive property.
The correct way to express the angle sum in the sine function is:
[tex]sin(a+b)=sin(a)cos(b)+sin(b)cos(a)[/tex]

Answers
Answer:
The correct answer is y = -3x + 1.
Step-by-step Explanation:
First, you need to use the point slope formula to determine the slope. This is determined by the formula of the second y-coordinate (the y-coordinate in the second ordered pair) minus the first y-coordinate (the y-coordinate in the first ordered pair).
When subtracting the two values, you receive 7 - -5. You would use the KCC (keep, change, change) rule and keep positive 7, change the minus to addition, and turn negative 5 into positive 5. This gives you a value of 12.
Then, you use the same formula layout for the x-coordinates. Take the x-coordinate in the second ordered pair and subtract the x-coordinate in the first ordered pair to get -2 - 2 = -4.
Finally, to determine the slope, divide 12 and -4 to get -3.
Then, to get the y-intercept placed at the end, you will need to substitute the coordinate values from one of the ordered pairs into the equation y = -3x + b. I chose to use the first ordered pair, so:
-5 = -3(2) + b (Multiply the slope by x to earn the new value)
-5 = -6 + b (Add the -6 to the -5 to isolate the b)
1 = b (b = 1) (Learn that b = 1)
Your final equation will be y = -3x + 1.
Answer:
The equation is y = -3x + 1.
Step-by-step explanation:
First, you have to find the gradient of the equation using the formula :
[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]
Let (x1,y1) be (-2,7),
Let (x2,y2) be (2,-5),
[tex]m = \frac{ - 5 - 7}{2 - ( - 2)} [/tex]
[tex]m = \frac{ - 12}{4} [/tex]
[tex]m = - 3[/tex]
Next, we have to use the slope-form equation y = mx + b where m is gradient and b is constant. So we have to find the value of c by substituing any coordinates into the equation :
[tex]y = - 3x + b[/tex]
Let x = 2,
Let y = -5,
[tex] - 5 = - 3(2) + b[/tex]
[tex] - 5 = - 6 + b[/tex]
[tex]b = 6 - 5[/tex]
[tex]b = 1[/tex]
Two cars leave towns 300 kilometers apart at the same time and travel toward each other. One car's rate is 14 kilometers per hour less than the other's. If they meet in 2 hours, what is the rate of the slower car?
Answers
Answer:
Say the first car speed as r
Second car speed will be r-14
Since rate times time equal distance, we have
r + (r -14)2 = 300
2r -14 = 300/2
2r = 150+14
r = 164/2 = 82
Speed of slower car 82-14 = 68 km/hr

On November 1, the balance of a credit card account is $2,835.63. There was a payment of $230.00 made on
November 12 as well as a new purchase for $121.36. On November 25, a second payment of $25.00 was made. The
annual interest on the account is 17.65%. Determine the finance charge for the account using both the average daily
balance and the adjusted balance methods. Which method would be more advantageous to the cardholder? Justify
your reasoning. Answer in complete sentences.
Answers
Answer:
The adjusted balance is generally the most advantageous billing method for the cardholder since the financial charges are lower ($39.20 < $40.07). This happens because interest is only charged on the final monthly balance, and cardholders can decrease that balance during any day of the billing cycle.
Step-by-step explanation:
November 1: balance $2,835.63
November 12: $230 payment
November 12: $121.36 purchase
November 25: $25 payment
annual interest 17.65%
average daily balance = {(11 x $2,835.63) + [13 x ($2,835.63 - $230 + $121.36)] + [6 x ($2,835.63 - $230 + $121.36 - $25)]} 31 days = ($31,191.93 + $35,450.87 + $16,211.94) / 30 days = $82,854.74 / 30 days = $2,761.82
financial charge = ($2,761.82 x 30 x 17.65%) / 365 = $40.065 ≈ $40.07
adjusted balance = $2,835.63 - $230 + $121.36 - $25 = $2,701.99
financial charge = $2,701.99 x 17.65% x 30/365 = $39.197 ≈ $39.20

Identify the transformation that results in an image that's not congruent to the pre-image. Question 9 options: A) Rotation B) Translation C) Dilation D) Reflection
Answers
Answer:
C) Dilation
Step-by-step explanation:
Rotation is simply rotating an object, therefore, the size and shape remain the same.
Translation is moving the object across the plane, and again, the size and shape will stay the same.
Reflection is reflecting a shape across a certain line. It will still keep its size and shape.
However, dilation is enlarging or shrinking a shape. This means that the shape will change size, but not shape. A dilation of a shape will be similar, but not congruent, to it.
