10. A rectangle has width the same as a side of a square whose perimeter is 20 m. the length
of the rectangle is 9 m. Find the perimeter of this rectangle.
Answer:
The perimeter of the rectangle is 28m
Step-by-step explanation:
Perimeter of a square = 4 x side length
20 = 4 x side length
side length = 20/4 = 5m
width of rectangle = 5m
length of rectangle = 9m
Perimeter of rectangle = 2(l + w)
= 2(9 + 5)
= 2(14)
= 28m

Step-by-step explanation:
The equation modeled by this throw is
-16t^2+8t+2
Using the vertex x coordinate formula of -b/2a,
we find that the x coordinate of the vertex is 0.25. Subbing 0.25 seconds for t into -16t^2+8t+2, we find out that the y value of the vertex is 3. This means the highest point reached by the ball is 3 feet and this takes 0.25 seconds

13. Solve 5x² - 6x + 1 = 0 using the quadratic formula.
please help me and show work
Answer: x= 1, [tex]\frac{1}{5\\}[/tex]
Step-by-step explanation:
The quadratic equation is
[tex]x=\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex]
and
[tex]x=\frac{-b-\sqrt{b^{2}-4ac } }{2a}[/tex]
So we just need to sub in the proper numbers from the equation given, in this case, it would result in
[tex]x=\frac{6+\sqrt{(-6)^{2}-4(5)(1) } }{2(5)}[/tex]
and
[tex]x=\frac{6-\sqrt{(-6)^{2}-4(5)(1) } }{2(5)}[/tex]
Once we get this we can either manually simplify or use a calculator, using a calculator would result in the answers
x= 1, [tex]\frac{1}{5\\}[/tex]

x = 8
Step-by-step explanation:
Since all the angles are congruent, this is an equilateral triangle. With an equilateral triangle, all sides are equal.
Which equation has no solution?
4(х + 3) 2x = 6(х + 2)
5 + 2(3 + 2x) = x4 3(х + 1)
5(х + 3) +х= 4(х + 3) + 3
4 + 6(2 + х) = 2(3х + 8)
Answer:
2? equation does not have a solution
Step-by-step explanation:
episode the ratio of males to females were 3 to 9 if there are 360 people at the fair how many males are there exact answer
Answer:
90 males
Step-by-step explanation:
3 males plus 9 females is 12 overall.
360/12 is 30 for each "1".
30 multiplied by 3 males is 90 males.
Hopefully that made sense. Sorry I'm bad at explaining.
find the defference between 5 2/7 and 2 2/4
Answer: 39/14
Step-by-step explanation:
Given
5 2/7 - 2 2/4
Convert mixed fraction to improper fraction
5 2/7 = (5 × 7 + 2) / 7 = (35 + 2) / 7 = 37/7
2 2/4 = (2 × 4 + 2) / 4 = (8 + 2) / 4 = 10 / 4 = 5/2
Find the common denominator for 37/7 and 5/2
First 10 multiples of 2 = 2, 4, 6, 8, 10, 12, 14, 16, 18, 20
First 5 multiples of 7 = 7, 14, 21, 28, 35
Since 14 is the first common multiple in the lists, 14 would be the common denominator of 37/7 and 5/2
Convert to the common denominator
(37 × 2) / (7 × 2) = 74 / 14
(5 × 7) / (2 × 7) = 35 / 14
Simplify by subtraction of numerator
=74/14 - 35/14
=(74 - 35) / 14
=[tex]\boxed{\frac{39}{14} }[/tex]
Hope this helps!! :)

Solve the formula for the specified variable P=wm
Answer:
below
Step-by-step explanation:
I'm not sure what variable you want to solve for but I'll solve for w and m if needed.
p = wm
~Divide w to both sides
p/w = m
p = wm
~Divide m to both sides
p/m = w

Given: Circle W W (-4, 6) Radius = 10 Units Which point lies on circle W?
The solution is : Option A is correct; Point Q is outside circle W
What is circle?A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “centre”. The perimeter around the circle is known as the circumference.
here, we have,
If the circle is given as having center W, this means the radius starts from point W and ends at any point on the circumference.
The radius has been given as 5 units, and this also means any measurement from point W to the circumference is either equal to or less than the radius which is 5 units.
Any measurement that is greater than 5 would be outside of the circumference.
we have,
Point Q is 6 units away from point W, therefore point Q is outside the circumference, that is, outside circle W.

Find x special right triangle
Answer:
[tex] \sin(45 ) = y \div 11 \sqrt{6} [/tex]
[tex] \frac{1}{ \sqrt{2} } = \frac{y}{11 \sqrt{6} } \\ \\ y = \frac{11 \sqrt{6} }{ \sqrt{2} } \\ y = 11 \sqrt{3} [/tex]
[tex] \tan(60) = \frac{x }{11 \sqrt{3} } \\ \\ \sqrt{3} = \frac{x}{11 \sqrt{3} } \\ x = \sqrt{3} \times 11 \sqrt{3} \\ x = 33[/tex]

calculate the absolute value
| 4 - 3x | = 5x + 4
Recall the definition of absolute value:
• |x| = x if x ≥ 0
• |x| = -x if x < 0
So we have 2 cases to consider:
• If 4 - 3x ≥ 0, then |4 - 3x| = 4 - 3x, and we have
4 - 3x = 5x + 4
8x = 0
x = 0
• If 4 - 3x < 0, then |4 - 3x| = -(4 - 3x) = 3x - 4, which gives
3x - 4 = 5x + 4
2x = -8
x = -4
However, keep in mind that |x| is always non-negative. If x = -4, then the right side of the equation becomes
5(-4) + 4 = -20 + 4 = -16 < 0
so the solution in this case is extraneous.

State if the given binomial is a factor of the given polynomial.
(2x^3+16x^2+22x-40) + (x+4)
Answer: Yes, (x+4) is a factor of the given polynomial.
==========================================================
Explanation:
We can use the remainder theorem here.
Consider any polynomial p(x). The binomial x-k will be a factor of p(x) if and only if p(k) = 0. I'm using the special case of the remainder theorem, where we look for a remainder of 0.
The binomial x+4 is the same as x-(-4). Compare this to x-k to see that k = -4.
Then plug this k value into the p(x) polynomial given
p(x) = 2x^3 + 16x^2 + 22x - 40
p(-4) = 2(-4)^3 + 16(-4)^2 + 22(-4) - 40
p(-4) = 2(-64) + 16(16) + 22(-4) - 40
p(-4) = -128 + 256 - 88 - 40
p(-4) = 0
This shows that dividing p(x) = 2x^3 + 16x^2 + 22x - 40 over x+4 leads to a remainder of 0. Therefore, (x+4) is a factor of p(x).

A group of friends in Chicago watched a televised bullfight. They ordered 3 pizzas ($15 each), 15 drinks ($1.50 each), and 6 large nachos ($5.80 each). After adding 5% and a 20% tip to the total, what did they pay for the food? (The tip is 20% of the total before the tax is added) around the answer to the nearest while cent
Answer:
$127.875
Step-by-step explanation:
cost of 3 pizzas= $15*3
cost of 3 pizzas=$45
cost of 15 drinks=$1.50*15
cost of 15 drinks=$22.5
cost of 6 nachos=$5.80*6
cost of 6 nachos=$34.8
Total cost = pizza cost+ drinks+nachos
total cost=$45+$22.5+$34.8
total cost=$102.3
Now ,
Tip cost=$102.3*20%
=$20.46
tex cost=$102.3*5%
=$5.115
Bill which all friends pay=total cost+ tip cost+tex cost
= $102.3+$20.46+$5.115
=$127.875
An elevator starts on the 15th floor, then rises 8 floors, drops 10 floors and rises 2 floor. What floor is the elevator on?
Answer:
15
Step-by-step explanation:
rises 8 floors = 15 + 8 = 23
drops 10 floors = 23 - 10 = 13
rises 2 floors = 13 + 2 = 15
