In the sport competition, France won more gold medals than Italy, who won more gold medals than Korea. If the total number of gold medals won by these three countries is three consecutive integers whose sum is 48, find the number of gold medals won by each.
Answer:
Korea = 15
Italy = 16
France = 17
Step-by-step explanation:
Let :
Korea = x
Italy = x + 1
France = x + 2
(since the values are consecutive)
x + x + 1 + x + 2 = 48
3x + 3 = 48
3x = 48 - 3
3x = 45
x = 45 / 3
x = 15
Korea = x = 15
Italy = x + 1 = 16
France = x + 2 = 17

Answer:
x = 28.1 (nearest tenth)
Step-by-step explanation:.since we are given two sides and an included angle, we would need to apply the Cosine Rule to find x. Thus,
x² = 18² + 14² - 2*18*14*Cos(122)
x² = 520 - (-267.079309)
x² = 520 + 267.079309
x² = 787.08 (approximated)
x = √787.08
x = 28.1 (nearest tenth)

1. Which three lengths could be the lengths
of the sides of a triangle?
O A.12 cm, 5 cm, 7 cm
O B.10 cm, 15 cm, 24 cm
O C.9 cm, 22 cm, 11 cm
O D.21 cm, 7 cm, 6 cm
Answer:
B
Step-by-step explanation:
For three side lengths to make a triangle, the two smaller ones have to add up to be greater than the third one. This is because if they are any smaller, they won't be able to touch and form a triangle. The formula for this is a+b>c.
You can go through each answer choice and determine whether or not it would work:
A. 12, 5, and 7
5 + 7 > 12 --> 12 > 12 (NOT true)
B. 10, 15, and 24
10 + 15 > 24 --> 25 > 24 (true!)
C. 9, 22, 11
11 + 9 > 22 --> 20 > 22 (NOT true)
D. 21, 7, and 6
7 + 6 > 21 --> 13 > 21 (NOT true)

Yasmine is having a birthday party with snacks and activities for her guests. At one table, five people are
sharing three quarters of a pizza. What equal sized portion of the whole pizza will each of the five people
receive
Use a modelle picture, number line, or manipulative materials) to represent the quotient
Write a numbentence to represent the situation in your reasoning
Answer: The answer is 3 over 20.
Step-by-step explanation: On offer is 3 over 4 pizza.
Each person is given a slice that that is the same size as all the rest.
So the 3 over 4 pizza is split into 5 equally sized parts. Thus each of the 5 slices is 1 over 5 times 3 over 4 = 1x3 over 5x4 = 3 over 20 of a whole pizza.
At Dizzy World theme park, Vera waited in line for 35 minutes and rode on a Magical Mushroom for 7 minutes. What is the percent value-added time for this ride
Answer: the percent value-added time for this ride is 16.67%
Step-by-step explanation:
Given that;
Waiting time for Vera = 35 minutes
Length of Vera's ride = 7 minutes
total processed time will; ( 35 + 7 ) = 42 minutes
the percent value-added time for this ride = ?
so
Percentage value-added time of Vera will be
= (length of the ride / total process time) × 100
we substitute
⇒ (7 / 42) × 100
⇒ 0.16666 × 100
⇒ 16.67%
Therefore the percent value-added time for this ride is 16.67%
A rectangle has a length that is 4 meters more than the width. The area of the rectangle is 117 square meters. Find the dimensions of the rectangle.
Answer choices are on picture.
Answer:
Its the first choice. Width:9 Length:13
Step-by-step explanation:
If the length is 4 meter more than the width than that means whatever the width is you must add 4 to it, in this case the width is 9 so add 4 to it which equals 13. If the length matches your answer it is the correct choice.
The area of a rectangle is the product of its dimensions. The dimension of the rectangle is: [tex]Length = 13m[/tex] and [tex]Width = 9m[/tex]
Given that:
[tex]L =4 + W[/tex]
[tex]Area = 117[/tex]
The area of a rectangle is:
[tex]Area = L \times W[/tex]
So, we have:
[tex]L \times W= 117[/tex]
Substitute [tex]L =4 + W[/tex]
[tex](4 + W) \times W = 117[/tex]
Expand
[tex]4W + W^2 = 117[/tex]
Rewrite as:
[tex]W^2 + 4W- 117 = 0[/tex]
Expand
[tex]W^2 + 13W - 9W - 117 = 0[/tex]
Factorize
[tex]W(W + 13) - 9(W + 13) = 0[/tex]
Factor out W + 13
[tex](W - 9)(W + 13) = 0[/tex]
Solve for W
[tex]W = 9[/tex] or [tex]W = -13[/tex]
The dimension cannot be negative.
So:
[tex]W = 9[/tex]
Recall that:
[tex]L =4 + W[/tex]
[tex]L = 4 + 9[/tex]
[tex]L = 13[/tex]
So, the dimension of the rectangle is:
[tex]Length = 13m[/tex]
[tex]Width = 9m[/tex]

Need help with trig!!
Answer:
a) sin x
b) cos² x
c) sin²x
Step-by-step explanation:
Step(i):-
Given that the trigonometric equation
[tex]tan(\frac{x}{2} ) + cos x tan (\frac{x}{2} ) = sin x[/tex]
we have to use trigonometric formulas
[tex]1-cosx = 2sin^{2} (\frac{x}{2} )[/tex]
[tex]sin x = 2 sin \frac{x}{2} cos\frac{x}{2}[/tex]
now
[tex]tan\frac{x}{2} = \frac{sin\frac{x}{2} }{cos\frac{x}{2} }[/tex]
= [tex]\frac{2sin(\frac{x}{2} ) sin\frac{x}{2} )}{2sin\frac{x}{2} cos\frac{x}{2} }[/tex]
= [tex]\frac{2sin^{2} (\frac{x}{2} ) )}{sinx }[/tex]
= [tex]\frac{1-cosx}{sinx}[/tex]
Step(ii):-
[tex]tan(\frac{x}{2} ) + cos x tan (\frac{x}{2} ) = \frac{1-cosx}{sinx} +cosx \frac{1-cosx}{sinx}[/tex]
= [tex]\frac{1-cosx +cosx(1-cosx)}{sinx}[/tex]
= [tex]\frac{1-cosx+cosx-cos^{2} x}{sinx}[/tex]
= [tex]\frac{1-cos^{2} x}{sinx}[/tex]
= [tex]\frac{sin^{2}x }{sinx}[/tex]

Answer:
z = 22
Step-by-step explanation:
Since this is a rhombus, we know that parallel sides are equal in length and that the angles should add to 360 degrees. The opposing angles, therefore, are also equal in size. So, you can find the answer by setting the two angles to each other.
3z = z + 44
2z = 44

twice a number is equal to six more than three times the number. write into equation
Answer:
2x = 3x + 6
Step-by-step explanation:
Key skills: Writing Out Equations
1) Let's say x is the number.
2) Twice the number means 2 times the number. This means it would be 2x.
3) 3 times a number is 3x. 6 more than that would be using addition, so it would be 3x + 6.
4) Therefore your answer would be 2x = 3x + 6

4 + 2p = 12
so p = what
Answer:
p=4
Step-by-step explanation:
4+2p=12
Step 1: Simplify both sides of the equation.
2p+4=12
Step 2: Subtract 4 from both sides.
2p+4−4=12−4
2p=8
Step 3: Divide both sides by 2.
2p/2=8/2
p=4
Answer:
p=4
Answer:
P = 4
Step-by-step explanation:
4 + 2p = 12
12 - 4 = 8
2p = 8
8 ÷ 2 = 4
P = 4

a taxi driver charges $1.25 per mile. the driver also chargers a one time $10 fee. write and solve a equation to determine how many miles are driven , for the driver to charge $39 total
Answer:
23.2 miles
Step-by-step explanation:
10 + 1.25x
x = number of miles
so if the total cost is $39, this is the equation:
10 + 1.25x = 39
Solve:
10 + 1.25x = 39
1.25x = 29
x = 23.2
So the answer will be 23.2 miles.
1) You have an ash tree and a magnolia tree in your yard. You chart the vertical growth of each tree.

b) Over five years, the magnolia tree grows 80 inches. Construct a double number line that represents the situation. How much does the tree grow each year? * This is a required question
c) Which tree has the faster growth rate? This is a required question
d) What is the growth rate of each tree in millimeters per day? *
Answer:8
Step-by-step explanation answe is 8beuase the tree
a)The unit rate of ash tree is equal to 25.5 inches per year .(Table attached) b) The magnolia tree grows by 16 inches every year.(Table attached)
c) Ash tree has the faster growth rate.
d) growth rate of ash tree = 1.77 mm
growth rate of magnolia tree =1.113 mm
What is a double number line ?Double number line diagrams are best used when the quantities have different units.
Given here, the ash tree grows 51 inches over two years therefore unit rate of growth is 51/2 = 25.5 inches/year. Similarly, the magnolia tree grows 80 inches over five years thus the tree grows by 16 inches every year. Finally converting the growth rate of each tree in mm per day we get
growth rate of ash tree = 25.5 × 25.4 / 365
= 1.77 mm
growth rate of magnolia tree = 16 × 25.4 / 365
=1.113 mm
Hence, clearly ash tree grows faster than the magnolia tree and refer to the attachments for the table and double number line.

Answer:
The correct answer is: Option D) 5
Step-by-step explanation:
Given equation is:
[tex]3(x + 2) + x = 2x + 16[/tex]
In order to find that which values of x makes the equation true, we have to put each value of x in the equation. When both sides of equations will be equal, that value of x will be true for the equation.
Putting x = 2
[tex]3(2 + 2) + 2 = 2(2) + 16\\3(4)+2 = 4+16\\12+2 = 20\\14 \neq 20[/tex]
Putting x = 3
[tex]3(3 + 2) + 3 = 2(3) + 16\\3(5)+3 = 6+16\\17+3 = 22\\20 \neq 22[/tex]
Putting x=4
[tex]3(4+2)+4 = 2(4)+16\\3(6)+4 = 8+16\\18+4 = 24\\22 \neq 24[/tex]
Putting x = 5
[tex]3(5+2)+5 = 2(5)+16\\3(7)+5 = 10+16\\21+5 = 26\\26 = 26[/tex]
The equation is true for x = 5
Hence,
