Members of a softball team raised $1319.25 to go to a tournament. They rented a bus for $776.50 and budgeted $41.75 per player for meals. Write and solve an equation which can be used to determine pp, the number of players the team can bring to the tournament.
Answer:
13 players
Step-by-step explanation:
Money Raised=RentedBus+Meals
1319.25=776.50+41.75p (p is for the number of players)(Now we solve for x)
Subtract 776.50 from both sides: 542.75=41.75x
Divide both sides by 41.75: 13=x
Remember that x is for the number of players so there'll be 13 players going to the tournament.

How does a geometric construction differ from a drawing?
Answer:
Constructing geometric figures means with the help of a compass, protractor and a scale with accurate measurement.
Drawing may just be drawing rough figures with no accurate measurement
Answer:
When you are constructing, you use tools like a compass, ruler, and protractor vs when you draw you don't use a tool, you free hand it.
Step-by-step explanation:
A geometric construction is a set of steps to create geometric figures using just a straightedge and a compass without using formal measurements; whereas a drawing can use any tool.

Answer:
x = 35
y = 7
Step-by-step explanation:
See how the image looks like two overlapping triangles. It is given that the triangles are congruent. Its easier to see whats what if you draw the triangles separately. I also flipped over the triangle on the right so they match. Record the given angle measures. Since A is 45° then D is also 45°. DBC is 30°, so we can find the missing angle in triangle DBC. Angles in a triangle add up to 180° so
C + 45 + 30 = 180
C + 75 = 180
C = 105°
This is angle DCB.
Now all the angles are marked. We can set up equations to find x and y. see image.

Nance is riding her bike to a friends house 4 and 1/2 miles away. She’s riding2 and 3/5 miles. How much farther does she need to ride.
Answer:
1 4/5 miles :)
Step-by-step explanation:
We first need to get them at a common denominator :)
4 1/2 = 4 5/10
2 3/5 = 2 6/10
Now we subtract :)
4 5/10 = 3 14/10
3 14/10 - 2 6/10 = 1 8/10 = 1 4/5

Nance still needs to ride 1 and 9/10 miles to reach her friend's house.
What is speed?Speed is a measure of how quickly an object moves from one place to another. It is defined as the distance traveled by an object per unit of time, and is often represented by the symbol "v". The formula for speed is:
Speed = Distance/Time
Nance is riding her bike to a friend's house that is 4 and 1/2 miles away. She has already ridden 2 and 3/5 miles. To find out how much farther she needs to ride, we can subtract the distance she has already ridden from the total distance:
Total distance = 4 and 1/2 miles
Distance already ridden = 2 and 3/5 miles
Total distance - Distance already ridden
4 and 1/2 - 2 and 3/5 = 9/2 - 13/5 (we need to get a common denominator)
= (45/10) - (26/10)
= 19/10
Therefore, Nance still needs to ride 1 and 9/10 miles to reach her friend's house.

The triangle circumscribes the circle. What is the perimeter of the triangle?
Answer:
P = 72 ft
Step-by-step explanation:
the perimeter P is the sum of the 3 sides.
Tangents to a circle from an external point are congruent , then
side 24 = 15 + 9
side 21 = 9 + 12
Third side = 12 + 15 = 27 ft
P = 24 + 21 + 27 = 72 ft

Answer:
[tex]\sf 343\dfrac{3}{4} \ mi[/tex]
1 inch = 125 miles
[tex]\rightarrow \sf 2\dfrac{3}{4} \ * \ 125[/tex]
[tex]\rightarrow \sf \dfrac{11}{4} \ * \ 125[/tex]
[tex]\rightarrow \sf \dfrac{1375}{4}[/tex]
[tex]\rightarrow \sf 343\dfrac{3}{4} \ mi[/tex]
Answer:
Option A
Step-by-step explanation:
Given:
1 inch = 125 milesTo avoid confusion, let's convert 2 3/4 into decimals. To convert a fraction into decimals, multiply and divide the fraction by 100.
⇒ (2 3/4 x 100)/100 = (11/4 x 100)/100 = (1100/4)/100 = 275/100 = 2.75
Now, multiply 2.75 to both sides of the equation "1 inch = 125 miles", as we need to find the actual distance of 2.75 inches
⇒ 1 inch = 125 miles
⇒ 1 × 2.75 = 125 × 2.75
⇒ 2.75 inches = 343.75 miles
The options given are in fraction form. So, we need to reconvert 343.75 into fraction form. Once again, multiply and divide the decimal by 100.
⇒ (343.75 × 100)/100 = (34375)/100
We can clearly tell that this is a mixed fraction because 34375 is greater than 100. To convert this fraction into mixed fraction, let's write the expanded form of this fraction.
⇒ (34375)/100 = 34000/100 + 300/100 + 75/100
⇒ (343 x 100)/100 + 75/100
⇒ 343 + 75/100 = 343 + 3/4
⇒ 343 3/4 miles (Option A)

Step-by-step explanation:
se upper and lower sums to approximate the area of the given region and given number of subintervals.
1. = from x=0 to x=1 with 4 subintervals.
2. = 4― from x=0 to x=2 with 4 subintervals.
3. = 1
from x=1 to x=2 with 5 subintervals.
The estimated areas are listed below:
The area of the function is approximately 0.806.The area of the function is approximately 2.088.The area of the function is approximately 0.696.How to approximate the area of a given region with a given number of subintervals
Right Riemann sum based on trapezoids offer a compact method that combines upper and lower sums, which is defined below:
[tex]A = \frac{b-a}{2\cdot n}\cdot \sum_{i = 0}^{n-1} [f(x_{i})+f(x_{i+1})][/tex] (1)
Where:
b - Upper bounda - Lower boundn - Number of subintervalsi - Subinterval indexIn this question we must apply right Riemann sums to estimate the areas of functions on given intervals. Now we proceed to solve each case below:
Case I ([tex]f(x) = \sqrt{x}[/tex], [tex]a = 0[/tex], [tex]b = 1[/tex], [tex]n = 4[/tex])[tex]A = \frac{1-0}{2\cdot (4)} \cdot [(0+\sqrt{0.5})+(\sqrt{0.5} + 1)+(1+\sqrt{1.5})+(\sqrt{1.5}+2)][/tex]
A ≈ 0.806
The area of the function is approximately 0.806. [tex]\blacksquare[/tex]
Case II ([tex]f(x) = 4\cdot e^{-x}[/tex], [tex]a = 0[/tex], [tex]b = 2[/tex], [tex]n = 4[/tex])[tex]A = \frac{2-0}{2\cdot (4)}\cdot [(4+1.472)+(1.472+0.541)+(0.541+0.199)+(0.199-0.073)][/tex]
A ≈ 2.088
The area of the function is approximately 2.088. [tex]\blacksquare[/tex]
Case III ([tex]f(x) = \frac{1}{x}[/tex], [tex]a = 1[/tex], [tex]b = 2[/tex], [tex]n = 5[/tex])[tex]A = \frac{2-1}{2\cdot (5)} \cdot [(1+0.833)+(0.833+0.714)+(0.714+0.625)+(0.625+0.556)+(0.556+0.5)][/tex]

In the given figure ABC is a triangle in which angle BAC is equal to 30 degree show that BC = the radius of the circumcircle of triangle ABC whose Centre is O.
Step-by-step explanation:
First, Join OB and OC.
∠BOC = 2∠BAC
(∵ angle subtended by an arc at the centre = double the angle subtended by it at any point on the remaining part of the circle)
=> ∠BOC = 2 x 30°...(∵ ∠BAC = 30°, Given)
=> ∠BOC = 60°
In, ΔOBC, OB = OC...(radii of same circle)
∴ ∠OCB = ∠OBC...(∠s opp. equal sides of a triangle are equal)
As the sum of angles of a traingle is 180°,
∠OBC + ∠OCB + ∠BOC = 180°
∠OBC + ∠OBC + 60° = 180°...(∵∠BOC = 60°,proved above)
2∠OBC = 120° => ∠OBC = 60°
Thus, we have ΔABC such that,
∠BOC = ∠OBC = ∠OCB = 60°
ΔOBC is an equilateral triangle
BC = OB i.e. BC is equal to the radius of circle.
Hence proved...Hope it helps you!!what are the missing reasons in the proof?
