Answer:
A=363
Step-by-step explanation:
To solve the area of a kite you use
[tex] a = \frac{pq}{2} [/tex]
So 22×33=726 then divide that by 2 and you get 363.
The area of a kite with diagonals of 22 feet and 33 feet is calculated as half the product of its diagonals, resulting in an area of 363 square feet.
Explanation:The area of a kite can be calculated by taking the product of the lengths of its diagonals and dividing by two. In the case of the kite with diagonals of 22 feet and 33 feet, we use the formula: Area = (diagonal1 × diagonal2) / 2. Substituting the given lengths into the formula, we get Area = (22 × 33) / 2.
To find the area, we multiply 22 feet by 33 feet which equals 726 square feet. Then we divide by 2, so the area of the kite is 363 square feet.

Answer:
x = 8
Step-by-step explanation:
Two secants drawn from an external point to the circle.
The (outside ) × (whole) of one secant is equal to the (outside) × (whole) of the other secant, that is
(x + 2)(x + 2 + 2x - 8) = (x + 1)(x + 1 + 2x - 5)
(x + 2)(3x - 6) = (x + 1)(3x - 4) ← expand both sides using FOIL
3x² - 12 = 3x² - x - 4 ( subtract 3x² - x - 4 from both sides )
x - 8 = 0 ( add 8 to both sides )
x = 8

9. Lula bought new furniture on her credit card for $993. If she pays it off in 6 months there will be no interest on her purchase. How much will her payments be if evenly distributed over 6 months?
Answer:
$165.50 dollars
Step-by-step explanation:
$993 / 6 = $165.50
Lula will need to pay $165.50 each month for 6 months to pay off her $993 furniture purchase without interest.
Lula purchased furniture on her credit card and plans to make payments over a period of 6 months with no interest charged. To calculate the monthly payment amount, you would divide the total cost of the furniture by the number of months over which she plans to pay.
The formula to find out the monthly payment is:
Monthly Payment = Total Cost / Number of Months
So for Lula, it looks like this:
Monthly Payment = $993 / 6
Monthly Payment = $165.50
Therefore, if Lula pays $165.50 each month, she will have the furniture paid off in 6 months without incurring any interest.

What is the positive solution to the equation 2x^2+25=73
Step-by-step explanation:
Because 1. x =(5-√73)/4=-0.886and the other one is 2. x =(5+√73)/4= 3.386
Final answer:
The positive solution to the equation 2x² + 25 = 73 is x = √24, which is approximately 4.9.
Explanation:
The student is asking for the positive solution to the equation 2x² + 25 = 73. To solve this, we first isolate the quadratic term by subtracting 25 from both sides of the equation, resulting in 2x² = 48. Then, we divide both sides by 2, simplifying to x² = 24. Taking the square root of both sides gives us two solutions, x = √24 and x = -√24. Since we're seeking the positive solution, we take the positive square root, which yields x = √24 or about 4.9.

Simplify 5(x - 6).
5x - 30
O-X
5x - 6
Answer:
[tex]5x - 30[/tex]
Step-by-step explanation:
We want to simplify
[tex]5(x - 6)[/tex]
We use the distributive property of real numbers which says that:
[tex]a(b + c) = ab + ac[/tex]
We apply the distributive property to get;
[tex]5(x - 6) = 5 \times x - 5 \times 6[/tex]
This implies that:
[tex]5(x - 6) = 5 x - 30[/tex]
Therefore the correct answer is 5x-30

The sides of a triangle are 9,11,13.The largest side of a triangle like this is 39.The other two sides of the second triangle are?
A) 18;22 B)27;33 C)3;11 3 D)48;50
Length of other two sides is 27:33
Option B
Step-by-step explanation:
Here we have , The sides of a triangle are in ratio 9:11:13.The largest side of a triangle like this is 39. Let's calculate other two sides of the second triangle:
[tex]9:11:13[/tex] is the ratio ,largest ratio value is 13 which represents largest side ratio whose length is 39 :
⇒ [tex]13x = 39\\[/tex]
⇒ [tex]x = \frac{39}{13}\\[/tex]
⇒ [tex]x = 3[/tex]
Now, other two sides are 9 x and 11 x
i.e. [tex]9x = 9(3) = 27[/tex]
[tex]11x = 11(3) = 33[/tex]
So, lengths of all the three sides are 27:33:39 . And, Length of other two sides is 27:33`
The sum of three consecutive integers is -234 find the integers
Answer:
-77, -78, -79
Step-by-step explanation:
let one of the integers be x
since the integers are consecutive, the other 2 integers must be
(x+1) and (x+2)
given that sum of the integers is -234,
x + (x+1) + (x+2) = -234
x + x + 1 + x + 2 = -234
3x + 3 = -234 (subtract 3 from both sides)
3x = -234-3
3x = -237 (divide both sides by 3)
x = -237 / 3
x = -79 (answer)
hence the other two numbers are
(x + 1) = -79 + 1 = -78 (answer)
and
(x+2) = -79 + 2 = -77 (answer)
Answer:
Step-by-step explanation:
let the first integer is 'x', and by adding 1 in it we get the second integer that is 'x+1', and for third integer we need to add 1 in the previous integer i.e. is 'x+1' we get 'x+2'. Now all three integers we have are
x,x+1 and x+2.
since sum or add all three integer we get -234. so
x+x+1+x+2=-234
x+x+x=3x, and 1+2=3
3x+3=-234
3x=-234-3
3x=-237
x=-237/3
now the first integer is -237/3 or -79,
second integer is -78 and third integer is -77.
for verification add all three to get -234.
-79-78-77=-234. hence proved.
The sum of two numbers is 98. If four times the smaller number is subtracted from the larger number, the result is 18. Find the two numbers,
The larger number is
The smaller number is
Hey there!
Let's make a system of equations using x and y to find the two numbers.X is smaller and y will be larger.
x+y=98
y-4x=18
Now, let's solve the bottom equation for y so we can use substitution.
y=18+4x
Now we plug this into the first equation.
x+18+4x=98
5x+18=98
5x=80
x=16
Now, we plug this into the first equation to find y.
y=82.
So, the larger number is 82 and the smaller number is 16.

Round 721295.198715 to the nearest ten.
To round 721295.198715 to the nearest ten, we increase the tens place from 9 to 0 due to the ones place being 5, resulting in 721300.
Explanation:To round the number 721295.198715 to the nearest ten, we should look at the digit in the ones place, which is 5. Since the ones digit is 5 or greater, we need to round up the tens place.
Therefore, the tens digit increases by one from 9 to 0, and all digits to the right of the tens place become zero.
Thus, 721295 rounds up to 721300 when rounded to the nearest ten.
Note that we ignore the decimal and its subsequent numbers because they do not influence the rounding of a number to the nearest ten.
Which of the following are possible equations of a parabola that has no real solutions and opens downward?
y>= -(x+4)^2 - 2
y>= -(x+4)^2 + 2
y>= -x2-2
y>=(x-4)^2 + 2

you want to leave a person a 25% tip. But how much of a tip would you leave her if your meal was $38.47
Answer:$48.09 please give brainliest!
Step-by-step explanation: you need to turn the percent to decimal so you move the decimal points to places to the right so the percent now is 0.25 so then you do 38.47 *0.25 =9.62 so then you add 9.62 +38.47 =48.09
Answer:
$9.62
Step-by-step explanation:
total cost= $38.47
tip = 25% = [tex]\frac{25}{100}[/tex]
=> tip = [tex]\frac{25}{100}[/tex] * $38.47
≈ $9.62 (to the nearest cent)
NOTE: the question is solely asking for the tip, therefore, there is no need to add the tip to the total.

How to solve -x+3y=4 ,3x+2y=-7
Answer:
x = -29/11 , y = 5/11
Step-by-step explanation:
-x+3y=4 ,..........(1)
3x+2y=-7 ............(2)
Solve simultaneously using elimination method
Multiply equation 1 by 3
It gives
-3x + 9y = 12
3x + 2y = -7..........(2) , add both equations
--------------------------
11y = 5
Divide both sides by 11
y = 5/11
Put value of y into equation (2)
3x +2y = -7
3x + 2(5/11) = -7
3x + 10/11 = '-7
Subtract 10/11 from both sides
3x +10/11 - 10/11 = -7 - 10/11
3x = -87/11
Divide both sides by 3
3x/3 = -87/11 ÷ 3
x = - 87/11 × 1/3
x = -29/11
Therefore x = -29/11 , y = 5/11

A group of 10 people is choosing a chairperson and vice-chairperson. They put all 10 people's names into a hat. The first name drawn becomes chair. The second name drawn becomes vice-chair. How many possible combinations of chair and vice-chair are there?
a.19
b.90
c.100
d.10! (10 factorial)
Answer:
a.
Step-by-step explanation:
A p-value less than 0.05 (typically ≤ 0.05) is statistically significant. It indicates strong evidence against the null hypothesis, as there is less than a 5% probability the null is correct (and the results are random). Therefore, we reject the null hypothesis, and accept the alternative hypothesis.
------------------------
First question:
The first question involves the test of an hypothesis.
Tests have significance levels, which normally are either 0.01, 0.05 or 0.1. If the p-value is less than the significance level, the results are significant, while if they are more, the results are not significant.
In this question, the p-value is 0.45, which is considerably more than any significance level, meaning that the results are nowhere near to being statistically significant, and the correct option is:
a. The results are nowhere near to being statistically significant.
