Answer:
obtuse scalene since 6 square plus 5 square is 36+25= 61, and 8 squared is 64, so 61<64, and if the legs are less than the hypotenuse, it would be an obtuse triangle. all the side are also unequal so it's a scalene.

please help! it’s due today haha it’s pythagoras
Answer:
x = 6.22 cm
Step-by-step explanation:
The lines on the sides of the triangle means they are the same length
Since it is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2
Substituting what we know
a^2 + a^2 = x^2
a=4.4
(4.4)^2 + (4.4) ^2= x^2
19.36 + 19.36 = x^2
38.72 = x^2
Taking the square root of each side
6.222539674 = x
Rounding to 3 significant figures
x = 6.22 cm
Triangle ABC is a right triangle. Triangle A B C is a right triangle. Angle A C B is 90 degrees, angle C B A is 31 degrees, and angle B A C is 59 degrees. What is the relationship between angles A and B?
Answer:
see explanation
Step-by-step explanation:
Complementary angles sum to 90°
∠ CBA = 31° and ∠ BAC = 59° , sum to 90° (31° + 59° = 90° )
Thus
∠ A and ∠ B are complementary angles
Answer: They are complementary

I need help i'm a 6th grader! I provided a screenshot. The math is inequalities!
If you know how to explain it please do! You don't have to though
Answer:
A or B
Step-by-step explanation:
[tex]3.5+m<4.6[/tex]
that's what it means
so if we solve it
[tex]3.5+m-3.5<4.6-3.5\\\\m+0<1.1\\\\m<1.1[/tex]
and now we check
[tex]3.5+(1)<4.6(\:something\:less\:than\:1.1)\\\\4.5<4.6[/tex]
which satisfy
now choose an option
it's either A or B
m<1.1 is the answer if you have to highlight the thing that m is less than then B is your answer
if you have to highlight an option that works then it's A

The table below shows the number of strawberries and cups of water
used to make fruit punch according to a certain recipe.
Strawberries Water (cups)
384
30
320
25
How many cups of water are needed for every 1 strawberry? Note:
Your answer may be exact or rounded to the nearest hundredth.
Answer:
5/64 of a cup.
Step-by-step explanation:
Is there two columns of data and two data points? Like this:
Strawberries Water
384 30
320 25
If so, then there are two ways to do it.
1) You can set up a ratio like this
384/30 = 1/x
Where x is the number of cups of water for 1 strawberry.
So,
x = 30/384 of a cup
x = 5/64 of a cup.
2) Look at the increase from one to the other.
64 strawberries requires 5 cups of water
Divide by 5 by 64 to get the water for one strawberry
5/64 of a cup.

1.) Identify the degree of the term 3xy4
Write the equation of the line that passes through (4,-3) & (3,0)
m =
b =
y =
Answer:
m = -3
b = 9
y = -3x + 9
Step-by-step explanation:
Let us solve the question
∵ The line passes through points (4, -3) and (3, 0)
∵ The rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex]
∵ (x1, y1) and (x2, y2) are 2 points on the line
∴ x1 = 4 and y1 = -3
∴ x2 = 3 and y2 = 0
→ Substitute them in the rule of the slope to find it
∵ m = [tex]\frac{0--3}{3-4}[/tex] = [tex]\frac{0+3}{-1}[/tex] = -3
∴ m = -3
∵ The form of the equation of the line is y = m x + b
→ Substitute the value of m in the form of the equation.
∴ y = -3x + b
→ To find b substitute x and y by the coordinates of the point (3, 0) or (4, -3)
∵ x = 3 and y = 0
∴ 0 = -3(3) + b
∴ 0 = -9 + b
→ Add 9 to both sides
∴ 9 = b
∴ b = 9
→ Substitute the value of b in the equation
∵ y = -3x + 9
∴ The equation of the line is y = 3x + 9
HeLP with this question please put the answer on a point
Answer:
[tex]x = -1[/tex]
[tex]y = 3[/tex]
Step-by-step explanation:
Given
The attached table
Required
Fill in the blanks
First, we need to calculate the slope
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Where:
[tex](x_1,y_1) = (1/2,1)[/tex]
[tex](x_2,y_2) = (3,-9)[/tex]
So, we have:
[tex]m = \frac{-9-1}{3-1/2}[/tex]
[tex]m = \frac{-10}{3-0.5}[/tex]
[tex]m = \frac{-10}{2.5}[/tex]
[tex]m = -4[/tex]
Next, we calculate the equation:
[tex]y - y_2 = m(x - x_2)[/tex]
This gives:
[tex]y - (-9) = -4(x - 3)[/tex]
[tex]y +9 = -4(x - 3)[/tex]
[tex]y +9 = -4x +12[/tex]
Make y the subject:
[tex]y = -4x +12-9[/tex]
[tex]y = -4x +3[/tex]
So,
When y = 7:
We have:
[tex]y = -4x +3[/tex]
[tex]7 = -4x +3[/tex]
Collect Like Terms
[tex]4x = 3 - 7[/tex]
[tex]4x = -4[/tex]
Divide through by 4
[tex]x = -1[/tex]
When x = 0, we have:
[tex]y = -4x +3[/tex]
[tex]y = -4 * 0 + 3[/tex]
[tex]y = 0 + 3[/tex]
[tex]y = 3[/tex]
jackie is solving this system of linear questions: 3x+2y= 20
4x-y=30
which equations could be part of the process of solving this system?
4x+6y=20
12x+8y=80
8x-y=60
8x-2y=60
Answer: 12x+8y=80
8x-2y=60
Step-by-step explanation:
The equations that could be part of the process of solving this system are 12x+8y=80 and 8x-2y=60.
The original equation was 3x+2y= 20 and 4x-y=30. Multiplying all through by 4 gives 12x+8y=80 and 8x-2y=60.
what is the constant of variation in this relation?
Answer:
Please check the explanation.
Step-by-step explanation:
We know that when 'y' varies directly with 'x', we get the equation
y ∝ x
y = kx
k = y/x
here k is the constant of variation.
From the table,
substitute x = -3, y = -4 in the equation
k = y/x
k = -4/-3
k = 4/3
substituting x = -2, y = -1
k = y/x
k = -1/-2 = 1/2
substituting x = -1, y = 2
k = y/x
k = 2/-1 = -2
substituting x = 0, y = 5
k = y/x
k = 5/0 = ∞
substituting x = 1, y = 8
k = y/x
k = 8/1
k = 8
substituting x = 2, y = 11
k = y/x
k = 11/2
substituting x = 3, y = 14
k = y/x
k = 14/3
It is clearly visible that there is no constant of variation because the ratio y = k/x is variating for different ordered pairs.
Thus, It is clear that none of the answers in the answer choices represent the constant of variation in this relation.

Wal-mart is advertising a back to school sale on markers. A pack of 12 sells for $6.97 whereas a 4 pack of the same brand cost for $2.77. Which is the better Buy? How do you know?
Answer:
12 for 6.97 is better
Step-by-step explanation:
for 12 pack
$6.97/12 markers = .58 per marker
for 4 pack
$2.77/4 markers = .69 per marker
thus 12 pack is better, a lower cost per marker
Answer:
12 for $6.97
Step-by-step explanation:
If u get 12 pack for $6.97 its .58 for each marker
If u get 4 pack for $2.77 its .69
And I would prefer to get a 12 pack cuz its cheaper and more markers.
I hope this helped:)
The ages of 10 friends are consecutive integers. The sum of their ages is 710. they get together every Tuesday to play cards and enjoy each other's company calculate their ages
Answer:
x = 66.5
x + 1 = 67.5
x + 2 = 68.5
x + 3 = 69.5
x + 4 = 70.5
x + 5 = 71.5
x + 6 = 72. 5
x + 7 = 73.5
x + 8 = 74.5
x + 9 = 84.5
Step-by-step explanation:
Given that :
Age of 10 friends are consecutive integers :
Let the ages be :
x, x+1, x+2, x+3, x+4, x+5, x+6, x+7, x+8, x+9
The sum of their ages = 710
Hence,
x + x+1 + x+2 + x+3 + x+4 + x+5 + x+6 + x+7 + x+8 + x+9 = 710
10x + 45 = 710
10x = 710 - 45
10x = 665
x = 665 / 10
x = 66.5
x + 1 = 67.5
x + 2 = 68.5
x + 3 = 69.5
x + 4 = 70.5
x + 5 = 71.5
x + 6 = 72. 5
x + 7 = 73.5
x + 8 = 74.5
x + 9 = 84.5
How many cubic blocks of side length 1/6 inch qould it take to fill a rectangular prism with a length, width and height of 1/3 inch, 2/3 inch, 2/3, respectively
Answer:
32 cubes
Step-by-step explanation:
I would first determine the volume in inches of the rectangular prism.
V = 1/3 x 2/3 x 2/3 = 4/27 cubic inches.
Then I would calculate the volume of the cube with 1/6 inch sides
V = 1/6 x 1/6 x 1/6 = 1/216 cubic inches.
Then I would divide the V of the large prism by the V of the small cube
(4/27) / (1/216) = (4/27) * (216/1) = 32 cubes

3(a + b)^2 = 81
(a + b)^2 = 27
a + b = sq rt 27
a + b = [tex]\sqrt{9}[/tex]· [tex]\sqrt{3}[/tex]

Write the equation of a line that is perpendicular to y= -1/3 x+6 and passes through the point (3,5).
Answer:
I think
y=1/3x-10/3
Step-by-step explanation:
Perpendicular Lines mean they have the negative reciprocal slope. This line has slope m = -1/3 so the perpendicular line has slope m = + 1/3
Our point is (3, 5)
Now use point slope form to find the equation: (y - y1) = m(x - x1)
(y - 5) = m(x - 3)
(y - 5) = 1/3(x - 3)
y -5=1/3x-10/3

please help
Question 1)
Given the points
(3, 5)(3, -6)Finding the slope between (3, 5) and (3, -6)
(x₁, y₁) = (3, 5)(x₂, y₂) = (3, -6)Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [-6 - 5] / [3 - 3]
= -11 / 0
= undefined or ∞
Thus, the slope of the line = m = undefined.
Note: The undefined slope means the line is vertical.
Question 2)
Given the points
(-6, 2)(8, 2)Finding the slope between (-6, 2) and (8, 2)
(x₁, y₁) = (-6, 2)(x₂, y₂) = (8, 2)Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [2 - 2] / [8 - (-6)]
= 0 / 14
= 0
Thus, the slope of the line = m = 0.
Note: The zero slope means the line is horizontal.
