The length of the base of an isosceles triangle is x. The length of a leg is 2x - 4. The perimeter of the triangle is 47. Find x.
Answer:
x = 11
Step-by-step explanation:
Remark
There are two legs. They are equal.
Equation
2x - 4 + 2x - 4 +x = 47 Combine like terms
Solution
5x - 8 = 47
5x - 8+8 = 47 + 8
5x = 55 Divide by 5
x = 11
Adam divides 32/8032. In which place should he write the first digit of the quotient?
Answer:
We have a quotient between a 2 digit number and a 4 digit number.
The usual rule for this type of problems is:
If the denominator has n more digits than the numerator, then the first digit will be in the nth position at the right of the decimal point.
If also, the denominator is larger than the numerator times 10^n, then the decimal will be moved another place to the right.
For example, if we divide 10 by 100 we have:
10/100
The denominator has one more digit than the numerator, then n = 1.
this means that the first digit of the quotient, will be on the first place at the left of the decimal point.
We can solve the quotient to get:
10/100 = 0.1
And, as we predicted, the first decimal is in the first place.
Now, with our quotient we have:
32/8032
n = 2.
and:
32*10^n = 3200
The denominator is larger than this, then we will move the first decimal to another place to the right.
Then we should expect to have the first decimal in the third place after the decimal point.
We can solve the quotient to get:
32/8032 = 0.0039
As we expected.

90 is 72 percent of what number
Answer:
x=125
Step-by-step explanation:
suppose the number is x
72% of x is 90
=> 0.72x=90
=> x=90/0.72
=> x=125
The 90 is 72 percent of approximately 125. In other words, if the unknown number is 125, 72 percent of 125 would be equal to 90.
To calculate the number that 90 is 72 percent of, we can set up the proportion:
90 is to x as 72 is to 100.
This proportion can be expressed as:
90/x = 72/100.
To solve for x, we can cross-multiply:
90 * 100 = 72 * x.
Simplifying the equation:
9000 = 72x.
Next, divide both sides of the equation by 72:
9000/72 = x.
x ≈ 125.
Hence, 90 is 72 percent of approximately 125. In other words, if the unknown number is 125, 72 percent of 125 would be equal to 90.

The area of a circle is 9π ft². What is the circumference, in feet? Express your answer in terms of \piπ. (pi)
Answer:
6π feet.
Step-by-step explanation:
The area = π r^2 = 9π
So r^2 = 9π/π = 9
r = 3 ft.
So the circumference = 2πr
= 2*π*3
= 6π feet.
The circumference of a circle with radius 3 feet is 6π feet.
What are the area and perimeter of a rectangle?We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.
We know the perimeter or circumference of a circle is 2πr and the area
is πr².
Given, The area of a circle is 9π ft².
Therefore, πr² = 9π.
r² = 9.
r = 3.
Now, we have a circle with a radius of 3 feet.
So, The circumference of the circle with radius 3 feet is,
= 2π×3 feet.
= 6π feet.
So, The circumference of the circle is 6π feet.

Malala is following this recipe for bread rolls.
She uses 200 ml of water.
How much of each of the other ingredients does she use?
Recipe: Makes 15 bread rolls
550 g flour
12 g salt
10 g yeast
30 ml oil
500 ml water
Answer:
Apart from the 200 grams of water, Malala will use 220 grams of flour, 4.8 grams of salt, 4 grams of yeast and 12 miligrams of oil.
Step-by-step explanation:
Since Malala uses 200 ml of water for her bread rolls, when the recipe indicates that 500 ml should be used, this implies that she is using 40% of the indicated measures.
Therefore, to know how much use of the remaining products, following with the same proportion, the following calculations must be made:
Flour: 550 x 0.4 = 220 g
Salt: 12 x 0.4 = 4.8 g
Yeast: 10 x 0.4 = 4 g
Oil: 30 x 0.4 = 12 ml

Use substitution to solve the
following system of equations.
-10x + 2y = 20 AND y = 3x + 2
pls pls help!
Answer:
(- 4, - 10 )
Step-by-step explanation:
Given the 2 equations
- 10x + 2y = 20 → (1)
y = 3x + 2 → (2)
Substitute y 3x + 2 into (1)
- 10x + 2(3x + 2) = 20 ← distribute parenthesis and simplify left side
- 10x + 6x + 4 = 20
- 4x + 4 = 20 ( subtract 4 from both sides )
- 4x = 16 ( divide both sides by - 4 )
x = - 4
Substitute x = - 4 into (2) for corresponding value of y
y = 3(- 4) + 2 = - 12 + 2 = - 10
solution is (- 4, - 10 )

Mo has five number cards.
Here is some information about his number cards.
• The cards are in ascending order.
• The range of the number cards is 32
The greatest number divided by the median number is 8
• The three numbers in the middle have a product of -36
What could Mo's number cards be?
Answer:
-16 -6 2 3 16
Step-by-step explanation:
Using basic knowledge of arithmetic operators, we find that a possible choice of Mo's number card is -16, -6, 2, 3 and 16.
What are arithmetic operators?The arithmetic operators perform addition, subtraction, multiplication, division, exponentiation, and modulus operations.
Given the information about the five numbers.
Let the five numbers be a < b < c < d < e.
Let a = -16 to begin with.
Given, range = 32 implies that e - a = 32.
e = 32 + a = 32 - 16 = 16
The greatest number divided by the median number is 8.
Greatest number = e = 16
Median = middle number = c
[tex]\frac{e}{c} = 8\\ \\c = \frac{e}{8} = \frac{16}{8} = 2[/tex]
The three numbers in the middle have a product of -36.
[tex]bcd = -36\\\\bd = \frac{-36}{2} = -18\\[/tex]
Since, bd = -18, one of b or d has to be negative.
We know, b < d, thus b is negative and d is positive number.
Also, b < 2 and d > 2.
The best possible choice is b = -6 and d = 3.
The 5 numbers chosen by Mo are -16, -6, 2, 3 and 16.
