____________________________________________________________________
it looks weird but it's basically asking how many triangles you can make with whatever description it gives- yea im stu.pid and dont understand it
Answer:
First one is one triangle.
Second one is one triangle.
Third one is no triangle (I think, I've never studied this kind of math before so I'm kinda stumped)
Very easy!! help!! urgent!! its on ratio
Answer:
A and B are correct
Step-by-step explanation:
if x:y is 1:3 then x is 1 and y is 3
1/3 of 3 is 1 so A is correct
3/4(1+3) is 3 so B is correct
But
1/4 × 3 is not 1 so C is not correct
3/4 ×1 is not 3 so D isn't correct
x greater than, less than, or equal to 73 degrees?

a large painting has a length of 18 inches and width of 12 inches. If each dimension is reduced by x inches to make the ratio of length to width 5 to 3, what is the value of x
Answer:
The value of x = 3.
Step-by-step explanation:
The ratio between length and width is given by:
[tex]\frac{L}{W}=\frac{5}{3}[/tex]
Where:
L represents the new length W represents the new widthNow, we know that each dimension is reduced by x inches, it means:
[tex]L=18-x[/tex]
[tex]W=12-x[/tex]
Then, we will have:
[tex]\frac{18-x}{12-x}=\frac{5}{3}[/tex]
Finally, we just need to solve it for x.
[tex]3(18-x)=5(12-x)[/tex]
[tex]5x-3x=60-54[/tex]
[tex]2x=6[/tex]
[tex]x=3[/tex]
Therefore, the value of x = 3.
I hope it helps you!

A meal that cost $50 had a 20% tip and 5% sales tax. How could you calculate your final total bill?
Answer:
$57.50
Step-by-step explanation:
find 10% of 50 first, which is 5, because 5 × 10 = 50, then add $10 to the $50 beacause 50 × 0.2 = 10, next, remove 5%, to do this divide 10% by 2 to get $2.50, 60 - 2.5 = 57.5

On a bicycle, Caitlyn rides for 4 hours and is 46 miles from her house. After riding for 7 hours, she is 79 miles away. What is her rate?
Answer:
Caitlyn's average is roughly 11.4.
Step-by-step explanation:
You get this by dividing 46 by 4, which gets you 11.5.
You then divide 79 by 7, that equals 11.3, rounded.
The number in-between the two numbers is 11.4.
Hope this helps!

−5x + y = −3
3x − 8y = 24
Answer:
x = 0
y = -3
Step-by-step explanation:
-5x + y = -3 --------------(I)
3x - 8y = 24 ------------(II)
Multiply the equation (I) by 8
(I)*8 - 40x + 8y = -24
(II) 3x - 8y = 24 {Add and y will be eliminated}
-37x = 0
x = 0
Plugin x = 0 in equation(I)
-5*0 + y = -3
0 + y = -3
y = -3
Answer:
- 5x + y =-3 ......1
3x -8y = 24.........2
eqn 1 is multiply by 8 .we get -40 x +8y=-24 .....3
-40 x +8 y =-24 ...........3
3 x - 8y = 24 ......... 2
·································
-37 x +0 = 0
··························
x =0
put x = 0 in equation 2
3 x -8 y =24
3×0 -8 y = 24
0 -8 y=24
-y =24÷8
-y =3
y = -3
ans ;
x = 0
y = -3

it's 14 cubic units.
Anyone know the answer to this?
Answer:
hello again
Step-by-step explanation:
the radius of the circle is 6mm
for having the circumference we need diameter
for having diameter we should multiply in 2
so:
[tex]d = 2r \\ \\ d = 2 \times 6 = 12mm \\ v = \pi \: d \\ v = 12\pi \: mm[/tex]
i hope this is the answer

2. A water tank is in the shape of a right circular cylinder with a height of 9
feet and a volume of 225 pi cubic feet. What is the diameter of the water
tank? *
Answer:
10 ft.
Step-by-step explanation:
V = Bh where B = area of the base, which is a circle in your problem.
So, B = [tex]\pi r^{2}[/tex]
225π = π[tex]r^{2}[/tex](9)
[tex]r^{2}[/tex] = 25
r = 5 ft
diameter = 2r = 10 ft.
3√-8/125 Evaluate 3 square root negative 8/125
Answer:
Your answer would be -2/5
Step-by-step explanation:
The value of the given expression is -2/5.
The given expression is [tex]\sqrt[3]{-\frac{8}{125} }[/tex].
How to solve cube roots?In mathematics, the definition of cube root is written as Cube root is the number that needs to be multiplied three times to get the original number. Now, let us look at the cube root formula, where y is the cube root of x. ∛x = y.
Now, [tex]\sqrt[3]{-\frac{8}{125} }[/tex] can be written as [tex]\sqrt[3]{(-\frac{2}{5})^{3} }[/tex].
Here, cube and cube root will get cancelled.
We get -2/5
Therefore, the value of the given expression is -2/5.

I need help with this equation for math
Answer:
The answer would be B
Step-by-step explanation:
the y-intercept would be a postive 4 and because it's a negative slope, it would rule out all of them except B.
Answer:
y = -1/2x +4
Step-by-step explanation:
We have two points so we can find the slope
m = (y2-y1)/(x2-x1)
= ( 0-4)/(8-0)
= -4/8
= -1/2
We know the y intercept is 4
The slope intercept form of the line is
y = mx+b where m is the slope and b is the y intercept
y = -1/2x +4
