Answer:
D
Step-by-step explanation:
there are 5 piles
dividing 100% by 5 gets 20%
some piles have less than 50 in it, so my answer would be D
Hope this helps, but I would wait for one more answer. I'm not quite sure about mine, but I think D would the most likely.
Let me know if it's wrong!
y=2x-3
y=x+2 system of equations
Answer:
x = 5
y = 7
Step-by-step explanation:
Since they are both equal to y, we can set them equal to each other.
2x - 3 = x + 2
Combine like terms and isolate the x.
x = 5
Plug in the x to either equation to get the value of y.
y = (5) + 2
y = 7

Why can you take the cube root of a negative number?
Answer:
you can because the real cube root of any negative real number is negative.
Step-by-step explanation:
Answer: The reason that we can't have the square (or quartic) root of a negative number is that two negatives always cancel to give a plus; so the square root of a negative number is undefined. ... The Real cube root of any negative Real number is negative.bc. a negativ number multiplied by it self 3 time result negativ too

Renting a tool form Store A costs $9.75 per hour plus a fee of $188.55. Renting the same tool
form Store B costs $15.99 per hour with no additional fee. Which inequality could be
used to
find the minimum number of hours, h, a tool must be rented so that the cost of renting the tool
at Store A is less then the renting it at Sore B?
F 188.55 > 15.99 + 9.75h
G 15.99h > 188.55 + 9.75h
H 9.75h < 188.55 + 15.99h

Answer:
True
Step-by-step explanation:
it is 3/5. Than 6/10 is equal to 3/5. Than 9/15 is equal to 3/5.
Answer: True
Step-by-step explanation:
That is true because let's take the first point for example.
3 cups of almonds for 5 cups of oats.
3/5 of 5 is 3
So that's correct.
If you still aren't sure you should try that with a different point. Hmm how about :
9 cups of almonds for 15 cups of oats
3/5 of 15 = 45/5 = 9
That's correct as well.
Hope these helps!

4(v+7) = -6(3v-4) +8v
Answer:
v=−27
Step-by-step explanation:
Since v is on the right side of the equation, switch the sides so it is on the left side of the equation.
−6(3v−4)+8v=4(v+7)
Simplify −6(3v−4)+8v
−10v+24=4(v+7)
Simplify 4(v+7).
−10v+24=4v+28
Move all terms containing v to the left side of the equation.
−14v+24=28
Move all terms not containing v to the right side of the equation.
−14v=4
Divide each term by −14 and simplify.
v=−27
The result can be shown in multiple forms.
Exact Form:
v=−27

a bag contains 4 blue and 6 green marbles. two marbles are selected at a random from the bag. if the first marble is not replaced before the second marble is drawn
Answer:
4 ÷ 10
Step-by-step explanation:
The computation of P is shown below:
If we add two marbles i.e.
= 4 + 6
= 10 marbles
Now if we draw the second marble
P(blue) = Blue marbles ÷ total marbles
= 4 ÷ 10
In the other case
P( blue second given a green first) = 4 ÷ 10

Factorise:
3x^2-2x-5
Answer:
( 3[tex]x[/tex] - 5 ) ( [tex]x[/tex] + 1 )
Step-by-step explanation:
[tex]3x^{2}[/tex] - 2[tex]x[/tex] - 5
(Multiply 3 from [tex]3x^{2}[/tex] with -5)
Product = -15
Sum = -2
(3 times - 5 gives the product '-15' and 3 plus -5 gives the sum -2)
[tex]3x^{2}[/tex] + 3[tex]x[/tex] - 5
3[tex]x[/tex] ( [tex]x[/tex] + 1 ) - 5 ( [tex]x[/tex] + 1 )
= ( 3[tex]x[/tex] - 5 ) ( [tex]x[/tex] + 1 )

An isosceles triangle has base 56 mm and
perpendicular height 45 mm
45 mm .
Work out the perimeter of the large triangle.
THE BASE OF THE LARGE TRIANGLE IS 168 Give your answer in mm.
Your final line should say, perimeter = ... m
Answer:
Step-by-step explanation:
Draw the altitude from the vertex angle to the base. You have two congruent, right triangles. The hypotenuse of each triangle is
√[(56/2)²+45²] = √[28²+45²] = √2809 = 53 mm
perimeter of larger triangle = 2×53 + 56 = 162 mm

Answer:
h = 13ft
Step-by-step explanation:
We can assume that the triangles are similar, so:
5 ft is to 26 ft as 2.5 ft is to h ft.
Which can be set up like this:
[tex]\frac{5}{2.5}=\frac{26}{h}[/tex]
We can cross multiply:
5h = (2.5) (26)
5h = 65
h = 13ft

Answer:
The solution of the first image is: b = √48
The solution of the second image is: c = √125
Step-by-step explanation:
Here we have two triangle rectangles, first, we need to remember the Pythagorean theorem.
For a triangle rectangle with cathetus A and B, and a hypotenuse H, we have the relationship:
A^2 + B^2 = H^2
Where H is the side that is opposite to the right angle (the angle of 90°)
In the first image, we can see that the hypotenuse is equal to 8, and one cathetus is equal to 4.
We want to find the value of b, that is the other cathetus.
Then we have:
4^2 + b^2 = 8^2
b^2 = 8^2 - 4^2
b^2 = 48
b = √48
Second image:
in this case, c is the hypotenuse, a and b are the cathetus.
We know that:
a = 5, b = 10
Then we have the equation:
a^2 + b^2 = c^2
Now we can replace the above values:
5^2 + 10^2 = c^2
25 + 100 = c^2
125 = c^2
√125 = c

Answer:
According to logarithmic properties.... The right hand side can be written as
log base 7 (180/3).....which is log base 7 60
So according to the question cancel out the log base 7 from both sides....
Then we get 8r + 20 = 60
That is 8r = 40..
That is r = 5......
Therefore the value of r is 5

Why is subtracting an expression similar to distributing a –1?
You increase each term inside the parentheses by –1 in order to subtract each term, since subtraction is the additive inverse.
You multiply each term inside the parentheses by –1 in order to add each term, since subtraction is the multiplicative inverse.
You multiply each term inside the parentheses by –1 in order to subtract each term, since subtraction is the multiplicative inverse.
You multiply each term inside the parentheses by –1 in order to subtract each term, since subtraction is the additive inverse.
Using the distributive property, distributing -1 ; multiplies each term in the parenthesis by a negative sign. Hence, it is similar to subtraction because You multiply each term inside the parentheses by –1 in order to subtract each term, since subtraction is the additive inverse.
The additive inverse of a value is the value which ensures that the addition of two values gives 0.
Using the relation :
(w + x) - (y + z)
The negative sign implies distributing -1 to all values in the parenthesis ;
w + x - y - z
Hence, it is similar to using the subtraction operation directly :
(w + x) - y - z
Therefore, subtraction ls similar to distributing - 1
