It’s the only one that makes 6What is the length of leg s of the triangle below?
Answer:
s = 10
Step-by-step explanation:
This Triangle is a Right Triangle with two equal sides ( because there are two equal angles )
Pytha. Theorem
A² + B² = C²
since we have two equal sides the A = B = s
then
s² + s² = c²
2s² = c²
2s² = (10sqrt2)²
2s² = 100 x 2
2s² = 200
s² = 200/2 = 100
s = sqrt ( 100 )
s = 10
Savannah's favorite candles are so popular that the price has been
increased. The price for a 24 oz. candle used to be $20, but now it is $28.
By what percentage has the price been marked up? *
Answer
70%
85%
48%
40%
Answer:
40%
Step-by-step explanation:
The increase was $8. Divide the increase by the original amount.
8/20 = .4
The decimal answer 0.4 converts to a percent answer of 40%. (.4×100=40)
The candle was marked up 40%.

Let :
wrapped candy = wlollipop = lgreen candy = gThe equations are :
w + w + l = 23l + l + 2l = 36w x w + g x g = 58w + w - g x l = 2Finding l
Using Equation 2, solve for the value of l4l = 36l = 36/4l = 9Finding w
Using Equation 1, solve for the value of w2w + l = 232w + 9 = 232w = 14w = 14/2w = 7Finding g
Using either equation 3 or 4, we can find gLet's go with equation 3w² + g² = 5849 + g² = 58g² = 9g = 3Solve the equation n2 − 29 = 260 by using square roots.

What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
Function representing the cost to the manufacturer is,
C(x) = -20x²+ 48000x + 19351
A function that represents the revenue generated is,
R(x) = -23x² + 114000x
Function representing profit to the company,
Profit = Revenue generated - Cost price
= -23x² + 114000x - ( -20x²+ 48000x + 19351)
= -23x² + 20x² + 114000x - 48000x - 19351
P(x) = -3x² + 66000x - 19351
Since this function is a quadratic function, the maximum price generated would be x = -b/2a
From the given quadratic function, a = (-3), b = 66000 and c = -19351
x = - 66000/ 2(-3)
x = -66000/-6
x = 11000
x = 11000 the profit to the company will be maximum.
That means pear company should produce 11000 phones for the maximum profit.

Meade gave 1/2 of a candy bar to Max and then ate 1/6 of the candy bar himself. What fraction of the candy bar is left?
There is ___ of the candy bar left.
Let's break this problem into a few steps:
First, Meade gave 1/2 of candy to Max⇒ Amount of Candybar: Candy - (1/2)Candy = (1/2)Candy
Second, Meade ate 2/5 of the candy⇒ Amount of Candy left:
Total amount of candy - (1/6) * Total amount of candy
= (1/2) Candy - (1/6) *(1/2)Candy
= (1 - 1/6) * (6/7) Candy
= 5/6 * 1/2 = 5/12 Candy
Thus there is 5/12 of the candy left.
What is the slope of the line that passes
* through the points (8, -9) and (1, 3)?
Answer:
[tex]\boxed{\sf{-\dfrac{12}{7} }}[/tex]Step-by-step explanation:
Use the slope formula.
[tex]\underline{\text{SLOPE FORMULA:}}[/tex]
[tex]\longrightarrow: \sf{\dfrac{y_2-y_1}{x_2-x_1} }[/tex]
y2=3
y1=(-9)
x2=1
x1=8
Rewrite the problem down.
[tex]\sf{\dfrac{3-(-9)}{1-8}=\dfrac{3+9}{1-8}=\dfrac{12}{-7}=\boxed{\sf{-\dfrac{12}{7} }}[/tex]
Therefore, the slope is -12/7.I hope this helps, let me know if you have any questions.
Answer:
[tex]\boxed{\text{Slope} = -\huge\text{(}\dfrac{12}{7}\huge\text{)}}[/tex]
Step-by-step explanation:
Slope formula:
[tex]\text{Slope} = \dfrac{\text{Rise}}{\text{Run}}} = \dfrac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
Using the coordinates (8, -9) and (1, 3), we obtain the following:
First point = (x₁, y₁) = (8, 9) = x₁ = 8 y₁ = 9Second point = (x₂, y₂) = (1, 3) = x₂ = 1 y₂ = 3Substitute the coordinates of both the points in the slope formula to obtain the fraction that represents the slope.
[tex]\implies \text{Slope} = \dfrac{3 - (- 9)}{1 - 8}[/tex]
To obtain a specific fraction or whole number that represents the slope, we need to simplify the numerator and the denominator.
[tex]\implies \text{Slope} = \dfrac{3 + 9}{-7}[/tex]
[tex]\implies \text{Slope} = \dfrac{12}{-7}[/tex]
Use parenthesis and take out the "negative sign" from the denominator.
[tex]\implies \boxed{\text{Slope} = -\huge\text{(}\dfrac{12}{7}\huge\text{)}}[/tex]

What are the next three terms in the given sequence?
3, 16, 29, 42,
A) 54, 66, 78
B)
55, 68,81
C) 1,2,3
D) 55,70,83
Answer:
B) 55, 68,81
Step-by-step explanation:
42-29=13
29-16= 13
So 42 + 13= 55
55+ 13= 68
68+ 13= 81
Answer:
B) 55, 68, 81
Step-by-step explanation:
Given sequence: 3, 16, 29, 42
To determine if the sequence is arithmetic or geometric, work out the difference in the terms.
[tex]\sf 3 \underset{+13}{\longrightarrow} 16 \underset{+13}{\longrightarrow} 29 \underset{+13}{\longrightarrow} 42[/tex]
This sequence adds 13 each time, so as the common difference is constant, it is an arithmetic sequence. To find the next term in the sequence, simply add 13 to the last term:
42 + 13 = 55
55 + 13 = 68
68 + 13 = 81
Therefore, the next three terms in the given sequence are 55, 68, 81
To solve this using the general form of an arithmetic sequence:
[tex]a_n=a+(n-1)d[/tex]
where:
[tex]a_n[/tex] is the nth terma is the first termd is the common difference between termsGiven:
a = 3d = 13[tex]\begin{aligned}\implies a_n & =3+(n-1)13\\ & = 3+13n-13\\ & = 13n-10\end{aligned}[/tex]
Therefore, the next 3 terms in the sequence are:
[tex]\implies a_5=13(5)-10=55[/tex]
[tex]\implies a_6=13(6)-10=68[/tex]
[tex]\implies a_7=13(7)-10=81[/tex]

Answer:
Total amount = $575.00I = PRT/100 = $75.00Equation:Total amount = interest + principle
Step-by-step explanation:
Formula:- I = PRT/100
Where,
I is interestP is principleR is rateT is time⇒ I = 500×5×3/100
⇒ I = 7500/100
⇒ I = 75
Interest is $75.00
The total amount accrued, principal plus interest, from simple interest on a principal of $500.00 at a rate of 5% per year for 3 years is $575.00.

Find the distance of CD and the coordinate of the midpoint of CD
Answer:
Explanation:
Formula to calculate the distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Therefore, length of CD having coordinates C(3,1) and D(3, 3),
[tex]CD=\sqrt{(3-3)^2+(1-3)^2}[/tex]
[tex]=2[/tex] [tex]units[/tex]
Formula to find the midpoint of CD is,
[tex]M=\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}[/tex]
[tex]=(\frac{3+3}{2},\frac{1+3}{2})[/tex]
[tex]=(3,2)[/tex]
Therefore, length of CD = 2 units and (3, 2) are the coordinates of the midpoint of CD.

A turtle lives in a garden and a hedgehog lives in the woods. They leave their homes at the same time walk toward each other and meet in 5 hours. The turtle walks 10 meters per hour slower than the hedgehog. If the turtle had left home 4 1/2 hours earlier than the hedgehog had left his home, the two would meet 150m from the woods. Find the distance between the garden and the woods. PLEASE EXPLAIN WHY.
Based on the calculations, the distance between the garden and the woods is equal to 383 meters.
How to calculate the distance.
First of all, we would assign a variable to the different speeds of the turtle and hedgehog as follows:
Let the turtle's speed be S₁.Let the hedgehog's speed be S₂.Mathematically, distance is given by this formula:
Distance = speed × time
Translating the word problem into an algebraic expression, we have;
If they both meet in 5 hours:
D = (S₁ + S₂) × 5
D = 5S₁ + 5S₂ ......equation 1.
Turtle's speed is 10 meters per hour slower than the hedgehog:
S₁ = S₂ - 10 .....equation 2.
If the turtle had left home 4.5 hours earlier than the hedgehog had left his home:
9.5S₁ + 5S₂ = D + 150 .....equation 3.
Substituting enq. 2 into eqn. 1, we have:
D = 5(S₂ - 10) + 5S₂
D = 5S₂ - 50 + 5S₂
D = 10S₂ - 50 .....equation 4.
Equating eqn. 3 and eqn. 4, we have:
10S₂ - 50 = 9.5(S₂ - 10) + 5S₂ - 150
10S₂ - 50 = 9.5S₂ - 95 + 5S₂ - 150
10S₂ - 50 = 14.5S₂ - 245
14.5S₂ - 10S₂ = 245 - 50
4.5S₂ = 195
S₂ = 195/4.5
S₂ = 43.3 m/h.
Now, we can find the distnace:
D = 10S₂ - 50
D = 10(43.3) - 50
D = 433 - 50
D = 383 meters.
