Answer:
The box contains 20 milk chocolates.
Step-by-step explanation:
Given that the chocolate box has milk chocolates and dark chocolates in a ratio of 2 milk chocolates for every 3 dark, and the total number of chocolates in the box is 50 units, to determine how many milk chocolates are in the box. it is necessary to perform the following calculation:
50 / (2 + 3)
50/5
10
Milk chocolates: 2 x 10 = 20
Dark chocolates: 3 x 10 = 30
Therefore, the box contains 20 milk chocolates.

This week, Tori ate 600 g of cheerios cereal.
That was 150% as much cereal as she ate last
week. How much cereal did Tori eat last week?
600 g is 150% of what number?
Step-by-step explanation:
600=150%
?= 100%
crossmultiplication
=400
600g=150%x
600 is therefore 150% of 400
The perimeter of a rectangular garden is 46 feet. The length of the garden is 5 feet less than three times the width. Find the area of the garden. The area of the garden is square feet.
Answer:
A = 112 square feet
Step-by-step explanation:
The perimeter of a rectangular garden is 46 feet.
P = 2(l+b)
46=2(l+b)
23 = (l+b) ....(1)
Let length is l and breadth is b.
The length of the garden is 5 feet less than three times the width.
l = 3b-5 ...(2)
Put equation (2) in equation (1)
23 = (3b-5+b)
23 = 4b - 5
28 = 4b
b = 7 feet
Pu b = 7 in equation (2)
l = 3(7)-5
l = 16feet
Area of a rectangle is given by :
A = lb
A = 16 × 7
= 112 ft²
So, the area of the garden is 112 square feet.

The diagonals of rhombus ABCD intersect at E. Given that m∠CAD=20° and CE=4, find the m∠BCA.
Answer:
BCA = 20 degrees
Step-by-step explanation:
A rhombus is an equilateral quadrilateral, with all four of its sides having the same length. In addition to that, one important geometric property that will really help us with this problem is the fact that the opposite sides of a rhombus are parallel.
This means that BC ||AD.
Consequently, because BC ||AD,
m∠CAD = m∠BCA.
This is because they are alternate angles.
The alternate angle equality can be used in geometrical problems where you detect two parallel lines cut across by a transversal. in this, our case, the parallel lines BC and AD were transversed by AC.
This makes m∠CAD = m∠BCA because they are alternate angles)

A projectile is thrown upward so that its distance above the ground after t seconds is given by the function h(t) = -16t2 + 704t. After how many seconds does the projectile take to reach its maximum height? Show your work for full credit. (2 points)
H(t) = -16t^2 +704t = -16(t^2 -44t)
Putting in vertex form: -16(t^2 -44t +484) + 704
h(t) = -16(t-22)^2 + 704
It takes 22 seconds to reach the maximum height, which is the vertex of the parabola at (22,704)
please mark me as the BRAINLIEST.....
Answer:
22 secondsStep-by-step explanation:
Given function:
h(t) = -16t² + 704tMaximum value is obtained at vertex. Using vertex formula to find the value of t at maximum height: x = -b/2a of a quadratic formula ax² + bx + c
t = -704/(-16*2) = 22Plz help I’ll give brainliest

Someone please help me
Answer: √117
Step-by-step explanation:
Since no diagram present, am assuming hypotenuse AB and right angle C. Let side opp angle B be b, and side opposite angle A be a. Altitude CD is x.
a^2 + b^2 = 22^2 (Pythagorean)
Using Pythag on two smaller triangles,
x^2 + 13^2 = a^2
x^2 + 9^2 = b^2
Substituting in first equation,
x^2 + 13^2 + x^2 + 9^2 = 22^2
x^2 = 117, so x = √117

The monthly fee to be a member is $25 and the total cost of membership, including the joining fee, would be $300 for 8 months. Write an equation for C,C, in terms of t,t, representing the total cost of the gym membership over tt months.
Answer:
C(t) = 25+34.37t
Step-by-step explanation:
It is given that,
The monthly fee to be a member is $25 and the total cost of membership, including the joining fee, would be $300 for 8 months.
We need to write an equation for C in terms of t representing the total cost of the gym membership over t months.
At t=0, Jonathan pays $25 as joining fee.
Equation will be :
C(t) = Co+kt
Initially, Co = 25
C(t) = 25
At t = 8,
C(8) = 25 + k(8) = 300
8k = 275
k = 34.37
⇒ C(t) = 25+34.37t
Hence, this is the required equation.
What is the area of rectangle VWXY?
Answer:
The area of the rectangle VWXY is 52 square units
Step-by-step explanation:
The formula of the area of the rectangle is A = L × W, where
L is the length of the rectangleW is the width of the rectangleIf a line segment has endpoints (x1, y) and (x2, y), then the line segment is horizontal and its length = x2 - x1If a line segment has endpoints (x, y1) and (x, y2), then the line segment is vertical and its length = y2 - y1From the given figure
∵ VWXY is a rectangle
∵ V = (3, -9) and W = (-1, -9)
∵ X = (-1, 4) and Y = (3, 4)
∵ Its length is WX or VY
∴ WX = VY
∵ Its width is VW or XY
∴ VW = XY
→ Let us find its length and its width
∵ Points W and X have the same x-coordinates
∴ y1 = -9 and y2 = 4
→ By using the 4th note above
∴ WX = 4 - -9 = 4 + 9 = 13
∴ L = 13 units
∵ Points X and Y have the same y-coordinates
∴ x1 = -1 and x2 = 3
→ By using the 3rd note above
∴ XY = 3 - -1 = 3 + 1 = 4
∴ W = 4 units
→ By using the formula of the area above
∵ A = 13 × 4
∴ A = 52 square units
∴ The area of the rectangle VWXY is 52 square units

If the diameter of 3 circles is in the ratio 4: 2: 1. The perimeter of the smallest circle is 8 cm. Then the area of
the shaded region is
Answer:
216[tex]\pi[/tex]
Step-by-step explanation:
Given the figure.
And the perimeter in the ratio 4: 2: 1.
Perimeter of smallest circle = [tex]8\pi[/tex]
To find:
Area of shaded region.
Solution:
To find the area, we need to have radius first.
And radius can be calculated by the given perimeter.
Formula for Perimeter is given as:
Perimeter = [tex]2\pi r[/tex]
[tex]8\pi = 2\pi r\\\Rightarrow r = 4\ cm[/tex]
Radius of smallest circle = 4 cm
Ratio of perimeter is equal to the ratio of the radii.
Radius of 2nd smallest circle by the given ratio = 8 cm
Radius of largest circle = 16 cm
Area of a circle is given the formula:
[tex]A = \pi r^2[/tex]
Area of the smallest circle = [tex]\pi 4^2 = 16\pi\ cm^2[/tex]
Area of the 2nd smallest circle = [tex]\pi 8^2 = 64\pi\ cm^2[/tex]
Area of the largest circle = [tex]\pi 16^2 = 256\pi\ cm^2[/tex]
Area of the shaded region = Area of largest circle + 2 [tex]\times[/tex] Area of 2nd smallest circle + 3 [tex]\times[/tex] Area of smallest circle - 2 [tex]\times[/tex] Area of smallest circle - 3 [tex]\times[/tex] Area of 2nd smallest circle
Area of the shaded region = Area of largest circle - Area of 2nd smallest circle + Area of smallest circle = [tex]256\pi - 64\pi +16\pi = 216\pi[/tex]
