Answer:
300
Step-by-step explanation:
120 is 40%
40% plus 40$ = 120+120=240
20% left.
120/2=60
240+60=300

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:
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

Can someone help me with this?
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!

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

Step 1: Define
f(x) = 4x² + 7x - 18
f(-9) is x = -9
Step 2: Evaluate
Substitute in x: f(-9) = 4(-9)² + 7(-9) - 18Evaluate Exponents: f(-9) = 4(81) + 7(-9) - 18Multiply: f(-9) = 324 - 63 - 18Subtract: f(-9) = 261 - 18Subtract: f(-9) = 243Why 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

What is a Function?A function is a law that relates two variables namely, a dependent and an independent variable.
A function always has a defined range and domain, domain is all the value a function can have as input and range is all the value that a function can have.
The function is of various types, logarithmic, exponential, quadratic, radical, etc.
The function is shown in the image,
The function is a hyperbolic function, represented by x²/a² -y²/b² = 1 for a hyperbola having a center at the origin.
The function can give any value from the set of real numbers and so,
The range of the function is a set of real numbers.

(4v-4)° (5v-5)°
Answer:
20v2−40v+20
Step-by-step explanation:
=(4v+−4)(5v+−5)
=(4v)(5v)+(4v)(−5)+(−4)(5v)+(−4)(−5)
=20v^2−20v−20v+20
= 20v^2-40v+20
You can easily do this by using the FOIL method.
F - first - in this case, 4v and 5v
O - Outside - in this case, 4v and -5
I - Inside - in this case, -4 and 5v
L - Last - In this case, -4 and -5
Then you find the like terms and add them together and then you have your answer which is also in standard form.

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
