Answer: 28
Step-by-step explanation:
Given
Kenny made 7 serves over the net for every 2 serves that did not go over the net i.e. success rate of Kenny is
[tex]\Rightarrow \text{success rate}=\dfrac{7}{2+7}\times 100=\dfrac{700}{9}\%[/tex]
for 36 serves, applying the same success rate, it is
[tex]\Rightarrow \text{success rate}=\dfrac{700}{9}\times\dfrac{1}{100}\times 36=28[/tex]
Serves that did not make over the net is [tex]36-28=8[/tex]
Thus, Kenny will make 28 serves that make over the net
Can someone help me with this question please? Many thanks in advance.
Jack, Alex and Amir jumped a total of 12.69 m in a long
jump competition.
Alex jumped exactly 200 cm further than Jack.
Amir jumped exactly 2,000 mm further than Alex.
What distance did they all jump?
Give your answers in metres.
Answer:
Step-by-step explanation:
The distances they jumped were
x,y,z
y=x+2
z=x+2+2=x+4
x+y+z=12.69
x+x+2+x+4=12.69
3x+6=12.69
3x=6.69
x=2.23
So Jack jumped 2.23m, Alex jumped 4.23m, and Amir jumped 6.23m.
!!!Please help will give the brainliest, and please do not put in a silly answer because you want some points or I will report you!!! What are the properties for each of these shapes and please be specific for each, a kite, trapezoid, square, rectangle, parallelogram, rhombus?
Answer:
The properties of trapezoid apply by definition (parallel bases).
The legs are congruent by definition.
The lower base angles are congruent.
The upper base angles are congruent.
Any lower base angle is supplementary to any upper base angle.
The diagonals are congruent.The bases are parallel by definition.
Each lower base angle is supplementary to the upper base angle on the same side.

A cattle rancher needs to construct a new silo in which to store cattle feed. The silo will cost $2000. The rancher pays 15% as a down payment and finances the balance for 60 months at an APR of 7.50% . Determine the rancher's total finance charge and monthly payment.
a) Total finance charge = $368.22; Monthly payment =$34.47
Answer:
Monthly payment = $34.06
Finance charge = $343.87
Step-by-step explanation:
Given that:
Cost of silo = $2000
Down payment = 15% = (0.15) * 2000 = $300
Loan amount = $2000 - $300 = $1700
Period = 60 months = 5 years
APR = 7.5%
Using then monthly payment calculator, with the satiated parameters inputted :
The monthly payment is $34.06
The total amount paid over 60 months = $2,043.87
Therefore, finance charge = (total amount paid - loan amount)
$2043.87 - $1700
= $343.87

Answer:
6) 15
7)5
8)120 degrees
9)60 degrees
10)9
Step-by-step explanation:
GHIJ is a parallelogram.
Opposite sides of a parallelogram are congruent.
3y - 1 = 2y + 1
3y - 2y = 1 + 1
y = 2
Opposite sides of a parallelogram are congruent.
4x + 3 = x + 12
4x - x = 12 - 3
3x = 9
x = 9/3
x = 3
6)GH = ?
GH = 4x + 3
GH = 4(3) + 3
= 12 + 3
= 15
therefore, GH = 15
7) HI = ?
HI = 2y + 1
= 2(2) + 1
= 4 +1
= 5
therefore, HI = 5
Opposite angles of a parallelogram are equal.
8) m(angle I) = 120 degrees...... (given)
therefore, measure of angle G = measure of angle I
therefore, m(angle G) = 120 degrees
Consecutive angles of a parallelogram are supplementary.
9) m(angle I) + m(angle J) = 180 degrees
120 + m (angle J) = 180
m(angle J) = 180 - 120
= 60 degrees.
The diagonals of a parallelogram bisect each other.
10) JK = 9 .........( given)
JK = HK
therefore, HK = 9

1. Get a blank paper or sugar board or cardboard/ calendar to complete the given task.
2. Use your pencil and compass to scribe or draw three different size circles on the blank paper/ calendar/ cardboard/sugar board
3. At the back of each circle label them 1,2 and 3 respectively.
4. Next use your ruler to measure the radius of the circle which is from the center to the circumference of the circle.
Ensure to record your measurement.
5. Use your ruler and measure the diameter goes straight across the circle, through the center (radius).
Ensure to record the measurements for each circle.
6. Then you will repeat steps 4 and 5, while using a string along with your ruler to measurement the circumference for each of the circle. Ensure to record your measurements
7. After completing your measurement write a conclusion for what you observed about the measurements for the diameter, radius and circumference for the three circles.
Answer:
R: Radius.
D: Diameter.
1) R: 4cm
D: 8cm
2) R: 2;5cm
D: 5cm
3) R: 2cm
D: 4cm
Conclusion: Note that the radius and diameter measurements vary depending on the circumference measurement.
(To graph use the measurements of the diameter)
Good luck! :)

Answer:
Y = 1
Step-by-step explanation:
Proportional
Answer:
y=1
Step-by-step explanation:
Because they are proportional, the two points have to be equal if they were like a fraction. This means (15,3) would be 15/3 which is equal to 5. The other point is (5,?), so that means that the point will have to be 1. This is because then the point will be equal to 5.
Hope this helps

Answer:
area of parallelogram = 21
area of trapezoid = 32
Step-by-step explanation:
Hello There!
The first figure shown is a parallelogram and the following dimensions are given
base = 7mm
height = 3mm
The area of a parallelogram can simply be found by multiplying the base by the height
so Area = 7 * 3
7 * 3 =21 so the area of the parallelogram is 21 square millimeters
The second figure given is a trapezoid and the following dimensions are given
height = 4m
base 1 = 5m
base 2 = 11m
To find the area of a trapezoid we use this formula
[tex]A=\frac{a+b}{2} h[/tex]
where a and b are bases and h = height
given the dimensions all we have to do is plug in the values into the formula
[tex]A=\frac{5+11}{2} 4\\5+11=16\\\frac{16}{2} =8\\8*4=32\\A=32[/tex]
so we can conclude that the area of the trapezoid is 32 square meters
Can you guys please help
Answer:
The length (which is the bottom and top lines) are both 9 inches long.
Step-by-step explanation:
To find the perimeter with only one given measurement and the total perimeter, first you need to double the given value. In this case it is 6 so 6 x 2 = 12. After that you need to find the rest of the sides so you can do 30 - 12 = x, or 12 + x = 30. As a total the answer is 18. Finally you divide 18 by two because there is two sides and you get 9.
find the 9th term of the geometric sequence 6,-24,96...
Answer:
A9 = 393216
Step-by-step explanation:
the first thing that will help you solve this question is finding the common ratio between each terms
the first thing that I like to do that usually helps is to take the second term (-24) and divide it by the first term (6) --> this will usually help you spot the common ratio fairly quickly
in your case, the common ratio is -4
- you can also check this by following my note above and then multiplying the second term by the common ratio to see if it matches the third term, which it does!
so now you can go about this two different ways
1. solve directly for the 9th term
2. use the nth term formula for geometric sequences
METHOD 1:
if you continue to multiply by -4 to solve for each term you would end up with:
6, -24, 96, -384, 1536, -6144, 24576, -98304, 393216
and you will recieve 393216 as your answer
METHOD 2:
the nth term formula is An = A1*r^(n-1)
where An = the nth term of the sequence
A1 = first term of the sequence (6)
and r = common ratio
using this formula, you would get:
A9 = 6(-4)^8
A9 = 393216
I hope this helped :)

Answer: positive, linear association
Step-by-step explanation: that is the answer, because the dots are rising up in a slope
Answer:
The answer is simple: Positive, linear association. Why is that? It is moving from left to right, increasing as it goes. That is a sign of a positive slope. And, this has a linear association because the points are jumbled together in a clear direction, so we know that we can place a line of best fit.

Answer:
a) 16.4 m, 101°b) 6.22 m, 51 m²Step-by-step explanation:
Find the measure of angle Q:
50° + (180° - 130°) = 100°a) Find PR using the law of cosines:
PR = √(8² + 13² - 28*13*cos 100°) = 16.4 m (rounded)Find ∠P using law of sines:
16.4/sin 100° = 13/ sin Pm∠P = arcsin (13 sin 100° / 16.4) = 51° (rounded)The bearing of R from P is:
50° + 51° = 101°b)
Find the measure of h, the distance from Q to PR:
h/ PQ = sin Ph = PQ sin Ph = 8 sin 51° = 6.22 mFind the area of ΔPQR:
A = 1/2PR*hA = 1/2(16.4)(6.22) = 51 m²A set cards has the numbers 1 through 25 on each card. Each numbers appears on exactly one card. What is P (less than8)?

Is 9/10, 1 1/5, 1 1/2 a right triangle?
Answer:
using Pythagoras theorem 11/2 is the largest side so let a=9/10 b=11/5 c=11/2
a²+b²=c²
(9/10)²+(11/5)²=(11/2)²
81/100+121/25=121/4
lcm of 25 and 100 =100
(81+484)/100=121/4
565/100=121/4
113/20=121/4
since they are not equal therefore it's not a right angle triangle
