Answer:
A, C
Step-by-step explanation:
hypotenuse (longest) cannot be more than the adjacent (shortest) + the opposite (2nd shortest)
___________________________________________________________
Answer:
1 < BC < 3
Step-by-step explanation:
like I said, the hypotenuse cannot be more than the adjacent plus the opposite, so the longest BC can go is 3 because 4 goes over 12 (9+4 is over 12)
What number is 10.5% of 65?
Answer:6.83
Step-by-step explanation:
Answer:
6.825
Step-by-step explanation:
100% is equal to 1.
So 10.5% is equal to 0.105.
Multiply by the percentage.
65 * 0.105 = 6.825

Answer:
the x-intercept is (-2,0) and the y-intercept is (4,0)
the slope (rise/run) is -1/2.
therefore the equation of the line is:
y=-1/2x+4
Answer:
y = 2/1x + 4
Step-by-step explanation:
The slope of line (m) is 2/1 and the y intercept is at 4 on y axis.

Which graph represents the equation below?
Answer:
c
Step-by-step explanation:
we can see that the "a" value is -1, written as just "-" meaning the parabola is going to face down, this eliminates A and D, then if we solve for the x intercepts, ( set the values in the parenthesis equal to 0) we see that the intercepts are negative one and positive 3
The graph which represents the equation f(x) = -(x + 1)(x - 3) is graph C.
Given a function that has the equation form:
f(x) = -(x + 1)(x - 3)
It is required to find the graph of this function.
The equation is clearly in the form of a factorized quadratic equation.
So the graph will be clearly parabola.
Now, when the equation is expanded, the equation will be of the form:
f(x) = -(x² -2x -3)
= -x² + 2x + 3
The leading coefficient is negative. So the parabola opens downward.
This eliminates options A and D.
The remaining options are B and C.
From the factored form, the zeroes of the function are:
-(x + 1)(x - 3) = 0
(x + 1)(x - 3) = 0
x = -1 and x = 3
That is, the graph touches the X-axis at x = -1 and x = 3.
The vertex coordinates are:
x = -b/2a = -2/-1 = 1
y = f(-b/2a) = -(1+1)(1-3) = 4
Hence the correct option is C.

Charles wants to compare the solutions to the equations x^2=64 and x^3=64.
Compare the signs of the solutions. Explain your reasoning.
Answer:
x = ±4
x = 4
Step-by-step explanation:
x² = 64.
Square root both sides
√x² =√64
x= ±8
When squaring both sides, the required solution is both positive and negative since the product of two negative number is positive.
x³ = 63.
Cube root both sides
3√x³ = 3√65
x =4
This only gives a positive number not negative since the product of three negative number gives a negative number

Can someone please help me this problem? Thanks :)
Answer: B) 2/3
====================================================
Work Shown:
Method 1
Apply the slope formula
m = (y2-y1)/(x2 - x1)
m = (3-1)/(-1 - (-4)) ..... using the first two rows as points
m = (3-1)/(-1 + 4)
m = 2/3 is the slope
-----------------------------------
Method 2
Each time y goes up by 2, x goes up by 3.
For instance, the jump from y = 1 to y = 3 is "plus 2". At the same time, the jump from x = -4 to x = -1 is "plus 3".
We can then say
slope = (rise)/(run)
slope = (change in y)/(change in x)
slope = (y increase by 2)/(x increase by 3)
slope = 2/3
Jeremiah threw 30 passes. He completed
24 of them. What percent of his passes
Answer:
80% of them made it in.
24/30=
8/10=
0.8
0.8 x 100=80
Answer:
He completed 80% of them and did not complete 20%.
Step-by-step explanation:
You can put this as a fraction because out of 30 passes he attempted, he made 24, so fraction is 24/30. To find the percent, you divide that and multiply by 100.
Percent:

Answer:
58%
Step-by-step explanation:
Lo siento. No soy bueno con el español, así que estoy usando translate. Espero que esté bien.
Entonces, para esta ecuación, usaremos un porcentaje igual o superior a 100 como se indica aquí. ([tex]\frac{es}{de}[/tex] = [tex]\frac{porciento} {100}[/tex]) Entonces tu ecuación es [tex]\frac{28}{49}[/tex] = [tex]\frac{x}{100}[/tex]
Multiplicará 28 por 100, lo que le dará 2800. Luego, dividiría 2800 entre 48, lo que le daría 58. Entonces, su respuesta sería x = 58%.

An object is moving at a speed of 7 meters every 9 days. Express this speed in centimeters per year. Round your answer to the nearest whole number.
Answer:
28400cm
Step-by-step explanation:
if 9 days=7m
:.365 days=?
365×7/9
283.88888
rounded off to nearest whole number =284m
change to cm=28400cm
The speed of the object expressed in centimeters per year and rounded to the nearest whole number is 28390 cm/yr
Speed per day = Distance / Number of days
Speed per day = 7 meters ÷ 9 days = 0.7778 m/day
Converting to centimeters per year :
1 meter = 100 cm1 day = 1/365 yearsHence,
0.7778 m/day = (0.7778 × 100cm) ÷ (1/365 years)
(0.7778 × 100cm) ÷ (1/365 years) = (77.78 cm ÷ 0.0027397 year)
0.7778 m/day = 28389.7 cm / year
Therefore, the speed of the object is 28390 cm/yr

Matt and Ash are selling fruit for a school fundraiser. Customers can buy small boxes of fruit or
large boxes of fruit. Matt sold 3 small boxes and 5 large boxes for a total of $47. Ash sold 11 small
boxes and 10 large boxes for a total of $114. What is the cost of a small box of fruit?
Answer: The cost of a small box is $4. The cost of a large box is $7.
Step-by-step explanation:
Let s = cost of a small box and L = cost of a large box
3s + 5L = 47
11s + 10L = 114
Multiply the top equation by -2 to combine with the second equation
-6s - 10L = -94
+11s +10L = 114
L cancels out, now solve for s
5s = 20
s = 4
Now, plug the value of s back into an equation to find the value of L
3(4) + 5L =47
12 + 5L = 47
5L = 35
L = 7
