Option C) Smith have to pay $180 at the time of purchase.
Step-by-step explanation:
Mrs. Smith wants to use an installment plan to buy a washing machine and dryer set priced at $1,500.
Therefore, the total cost = $1500The down payment for the installment plan is 12%.We need to find the payment amount at the time of purchase.
This can be calculated by finding the 12% of the total price $1500.
Smith have to pay at the time of purchase = 12% of 1500
⇒ (12/100) × 1500
⇒ 12 × 15
⇒ 180
Hence, option C) $180 is the amount need to be paid by the Smith at the time of purchase.
Mrs. Smith will have to pay $180 at the time of purchase, not including taxes. This matches option B.
To find the down payment Mrs. Smith has to pay at the time of purchase, we need to calculate 12% of the total price of the washing machine and dryer set.
The total price of the set is $1,500.
The down payment is 12% of this price.
To calculate the down payment, we multiply the total price by the down payment percentage:
Down payment = Total price x Down payment percentage
Down payment = $1,500 x 12%
First, we convert the percentage to a decimal by dividing by 100:
12% = 12 / 100 = 0.12
Now we can calculate the down payment:
Down payment = $1,500 x 0.12
Down payment = $180
Therefore, Mrs. Smith will have to pay $180 at the time of purchase, not including taxes. This matches option B.

The expected value of the given scenario is -$4.80
What is probability?The probability of an event is a number that indicates how likely the event is to occur. It is expressed as a number in the range from 0 and 1, or, using percentage notation, in the range from 0% to 100%. The more likely it is that the event will occur, the higher its probability.
The expected value refers to the value for a person who decides to purchase one ticket.
And that value is the sum of the values of the different possible scenarios.
There are two scenarios, wining and losing.
Note that we need to subtract the cost of the ticket (i.e. $5) from the return.
Winning :-
Probability 1 out of 500 chances
Return expected: ($100 - $5) *1/500 = $95 * 1/500 = $0.19
Losing :-
Probability 499 out of 500 chances
Return expected: (0 - $5)*499/500 = -$4.99
The expected value is the sum of the two returns: $0.19 - $4.99 = -$4.80 (it is negative).

Paula designed a three-dimensional scale model of a department store. The volume of the scale model was 35 cubic feet. The ratio of the dimensions of the model to the dimensions of the store was 1:20. Determine the volume of the actual department store that Paula planned to build
Answer:
700 cubic feet
Step-by-step explanation:
Volume of scale model = 35 cubic feet
ratio of the dimensions of the model to the dimensions of the store was 1:20
Therefore
dimensions of the model/ dimensions of the store = 1/20
we know that in scaling
dimensions of the model/ dimensions of the store = Volume of scale model / volume of the actual department store
Now substituting the value of scale model in the above ratio equation we have
1/20 = 35/volume of the actual department store
=> volume of the actual department store = 35*20 = 700
Therefore volume of the actual department store is 700 cubic feet

The sum of -4 and 5 times a number is multiplied by 3. The result is 212 less than 7 times the number. What is the number?
Answer:
-25
Step-by-step explanation:
(-4 + 5n) × 3= 7n - 212
-12 + 15n = 7n - 212
8n = -200
n = -25
Answer:
The number is -25
Step-by-step explanation:
(-4 +5n)*3 = 7n-212
Distribute
-12 +15n = 7n -212
Subtract 7n from each side
-12 +15n-7n = 7n-7n -212
-12 +8n = -212
Add 12 to each side
-12+12 +8n = -212+12
8n = -200
Divide each side by 8
8n/8 = -200 /8

Select the expression equal to square root of 24
look at the attached picture⤴
Hope it will help u...
Final answer:
To express the square root of 24 in simplest radical form, we break down 24 into 4 and 6, and since 4 is a perfect square, the simplified expression is 2√6.
Explanation:
To find the expression equal to the square root of 24, we can simplify the square root by looking for perfect square factors within 24. The number 24 can be factored into 4 and 6, where 4 is a perfect square. Therefore, we have:
√24 = √(4 × 6)√24 = √4 × √6√24 = 2√6As a result, the simplified expression equal to the square root of 24 is 2√6.
inverse cosine is used to find to find a given angle measure when we know the ________ and the ______.
Answer: adjacent and hypotenuse
Step-by-step explanation: Cos theta is adjacent/Hypotenuse
Final answer:
Inverse cosine is used to find an angle measure when we know the length of the adjacent side and the hypotenuse in a right triangle.
Explanation:
The inverse cosine function, also known as arccosine, is used to find a given angle measure when we know the length of the side adjacent to the angle and the length of the hypotenuse of a right triangle. The cosine of an angle in a right triangle is defined as the ratio of the length of the adjacent side to the length of the hypotenuse. By using the inverse cosine function, we can find the angle whose cosine is the given ratio. This is particularly useful in trigonometry for solving right triangles or when dealing with any scenario where angle and side lengths are related through the cosine ratio.
In mathematical terms, if we have a right triangle with an angle labeled as θ (theta), and we know the lengths of the side adjacent to θ (adjacent) and the hypotenuse (hypotenuse), the cosine of θ is given by-
cos(θ) = adjacent / hypotenuse
To find the angle measure θ based on the ratio of these two sides, we would compute-
θ = arc cos(adjacent / hypotenuse).

C C) Focus: (1,31/2); Directrix: y = 41/2
CD) Focus: (-1,31/2); Directrix: y = 41/2
Answer is B! Correct on exam!
Step-by-step explanation:
1. Identify the values for a, h, and k: a= 1/2 h= -1 k= 4. (Remember that the sign of h changes!)
2. Determine vertex: (-1,4)
3. Determine x and y for focus: X= -1 (same as vertex) y= K + 1/4(a)
Substitute what we know into that formula: y= 4 + 1/4(1/2)
y= 4 + 1/2 so y= 4 1/2.
4. Determine directrix: y= k - 1/4(a) ]
Substitute in what we know: y= 4 - 1/4(1/2)
y= 4-1/2 so y= 3 1/2
The focus and directrix of the parabola are (-1, 9/2) and y=7/2 respectively.
The given function is y = 1/2(x+1)² + 4.
We need to find the focus and directrix of the parabola.
What are focus and directrix?A parabola is a set of all points in a plane which are an equal distance away from a given point and given line. The point is called the focus of the parabola and the line is called the directrix. The focus lies on the axis of symmetry of the parabola.

How much grain can this container hold? Express your
answer in terms of it. It’s a cylinder
4 in.
11 in.
176pie in.3
88pie in.3
44pie in.3
484pie in.3
Answer:
[tex]176\pi in.^3[/tex]
Step-by-step explanation:
The figure of the problem is missing: find it in attachment.
In this problem, the container has a shape of a cylinder.
The volume of a cylinder is given by the formula:
[tex]V=\pi r^2 h[/tex]
where
V is the volume
r is the radius of the base of the cylinder
h is its height
For the container in this problem, we have:
r = 4 in. is the radius of the base
h = 11 in. is the height of the container
Substituting into the formula, we can find the volume of the container, and so the volume of grain that it can contain:
[tex]V=\pi (4)^2 (11)=176\pi in.^3[/tex]
The given cylinder container can hold 44π cubic inches of grain. This is calculated using the formula for the volume of a cylinder which is πr²h.
Explanation:To compute the amount of grain a cylindrical container can hold, you would have to calculate the cylinder's volume. The formula for the volume of a cylinder is πr²h, where r represents the radius, and h represents the height.
In this case, the diameter is 4 inches, so the radius (r) would be 2 inches. The height (h) of the cylinder is 11 inches. So, substituting these values into the formula gives us:
Volume = π(2²) x 11 = 44π cubic inches

D) 2(ab + 1)
E) a2 + b2 + 1
Answer:
D
Step-by-step explanation:
2 multiplying by any number even or odd=even number
Final answer:
The correct answer is D) 2(ab + 1), because multiplying an odd number (ab + 1) by 2 results in an even number.
Explanation:
The question asks which expression must be even if integers a and b are even. We know that the product of two even numbers is always even. Therefore, ab is even.
When we add 1 to an even number, the result is odd, so ab + 1 is odd. Multiplying by 3, as in option C, won't change the oddness, so 3(ab + 1) is also odd. The expression in option E, a2 + b2 + 1, will be odd for the same reason - the sum of even squares is even, and adding 1 makes it odd.
However, option D multiplies the odd number ab + 1 by 2, guaranteeing that the result is even regardless of the values of a and b since any number multiplied by 2 is even. Thus, the correct answer is D) 2(ab + 1).
Khan academy use Pythagorean theorem to find isosceles triangle size length
Answer:
I know
Step-by-step explanation:
The length of each equal side of the isosceles triangle Pythagorean theorem is equal to the square root of half the square of the length of the base.
The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
To find the length of an isosceles triangle, we need to consider the two equal sides as the legs of a right-angled triangle, and the remaining side as the hypotenuse.
Let's denote the length of the equal sides as "a" and the length of the remaining side (the base) as "b".
According to the Pythagorean theorem, we have:
[tex]a^2 + a^2 = b^2[/tex]
Simplifying this equation, we get:
[tex]2a^2 = b^2[/tex]
To find the length of the equal sides, we can solve for "a" by taking the square root of both sides:
[tex]a = \sqrt{b^2 / 2}[/tex]
Therefore, the length of each equal side of the isosceles triangle Pythagorean theorem is equal to the square root of half the square of the length of the base.
