Answer:14
Step-by-step explanation:
I have a friend Robert who is an expert at taking the difference of consecutive perfect squares. This means that if I give him a number $x$, he immediately computes $$x^2 - (x - 1)^2$$and gives me the result. I decided one day to first give Robert the number $9$, then the number $6$, and finally the number $4$. Robert gave me three numbers in return. What is the sum of these three numbers?
Answer:
35
Step-by-step explanation:
Please look at the attachment down below.
Hope this helped! :)
The sum of three number is 35.
What is Square?A square number is the result when a number has been multiplied by itself.
For example, 25 is a square number because it's 5 lots of 5, or 5 x 5.
Given:
if the number given is 9
9² - (9 - 1)² = 9² - 8²
= 81-64
= 17.
if the number given is 6.
6² - (6 - 1)² = 6² - 5²
= 36-25
= 11.
if the number given is 4.
4² - (4 - 1)²= 4² - 3²
= 16-9
= 7.
Thus, the sum of three number is
=17 + 11 + 7
= 35

A 40cm length of wire is used to form a rectangle. The width of
the rectangle is 2cm longer than the height.
What is the length of the shortest side?
Answer:
9cm
Step-by-step explanation:
to solve first divide the total perimiter (40cm) by 4
this would allow 10cm for each side to allow the longer side to be 2 cm longer than the height we must subtract 1cm (for a total of 2cm) from each side of the rectangle, this would result in the shorter side having a length of 9cm

Answer:
33 ft²
Step-by-step explanation:
Each triangle's area is given by the formula ...
A = (1/2)bh
A = (1/2)(3 ft)(4 ft) = 6 ft²
The square base area is given by ...
A = s²
A = (3 ft)² = 9 ft²
__
The total area of the pyramid is the area of the base plus the area of four triangular faces.
Total Area = (9 ft²) + 4(6 ft²) = (9 +24) ft²
Total Area = 33 ft²

The graph crosses the vertical axis 2 squares below 50.
Then y- intercept = 30
There are 195 adults and 320 children at a zoo. The zoo makes a total of $6,515 from the entrance fees, and the cost of an adult and a child to attend is $27, how much does it cost each for a parent and a child? Let a represent an adult. Let c represent a child. Enter a system of equations to represent the situation, then solve the system.
Answer:
a+c=27
195a+320c=6515
Step-by-step explanation:
adult (a): 195
children (c): 320
total $: $6515
child $: 27
a+c=27 --> c=-a+27
195a+320c=6515
sub the first equation into the 2nd equation to get a=17
sub a=17 into c=-a+27 to get c=10
so, an adult ticket is $17 and a child ticket is $10.

Mario and Luigi ran laps to train for their race. The ratio of number of laps Mario ran to the number of laps Luigi ran was 4:5. If they ran a total of 27 miles, how many miles did Luigi run
Answer:
15 miles
Step-by-step explanation:
They both ran a total of 9 laps and 9 laps = 27 miles
This means each lap is 3 miles.
So Luigi ran 15 miles cause he ran 5 lap and each lap is 3 miles

Step-by-step explanation:
Estimate the total weight of two million pounds worth of two pence coins in kilograms. A two pence coin weighs 7.1g.
Answer: 710,000 kg
Step-by-step explanation:
There are 100 pence in one pound.
The number of two pence coins in 1 pound is therefore:
= 100 / 2
= 50 coins
In 2 million pounds therefore, there will be:
= 50 * 2,000,000
= 100,000,000 two pence coins
If one coin weighs 7.1g, weight is:
= 100,000,000 * 7.1
= 710,000,000 g
A kg is 1,000 grams so the weight in kg is:
= 710,000,000/1,000
= 710,000 kg
A model of a famous statue is 3 1/2 inches tall. The actual statue is 5 1/4 feet tall. What is the ratio of the height of the model to the height of the actual statue in simplest form?
Given:
A model of a famous statue is [tex]3\dfrac{1}{2}[/tex] inches tall. The actual statue is [tex]5\dfrac{1}{4}[/tex] feet tall.
To find:
The the ratio of the height of the model to the height of the actual statue in simplest form.
Solution:
We have,
Height of the model = [tex]3\dfrac{1}{2}[/tex] inches
Height of the actual statue = [tex]5\dfrac{1}{4}[/tex] feet.
Now, the ratio of the height of the model to the height of the actual statue is:
[tex]\text{Ratio}=\dfrac{\text{Height of model}}{\text{Height of actual statue}}[/tex]
[tex]\text{Ratio}=\dfrac{3\dfrac{1}{2}\ in.}{5\dfrac{1}{4}\ ft}[/tex]
[tex]\text{Ratio}=\dfrac{\dfrac{3(2)+1}{2}\ in.}{\dfrac{5(4)+1}{4}\ ft}[/tex]
[tex]\text{Ratio}=\dfrac{\dfrac{7}{2}\ in.}{\dfrac{21}{4}\ ft}[/tex]
We know that 1 ft = 12 in.
[tex]\text{Ratio}=\dfrac{\dfrac{7}{2}\ in.}{\dfrac{21}{4}\times 12\ in.}[/tex]
[tex]\text{Ratio}=\dfrac{\dfrac{7}{2}\ in.}{21\times 3\ in.}[/tex]
[tex]\text{Ratio}=\dfrac{7}{2\times 21\times 3}[/tex]
[tex]\text{Ratio}=\dfrac{1}{2\times 3\times 3}[/tex]
[tex]\text{Ratio}=\dfrac{1}{18}[/tex]
Therefore, the ratio of the height of the model to the height of the actual statue in simplest form is [tex]\dfrac{1}{18}[/tex].

Hey there!
The answer to your question is infinitely many solutions.
First, we will simplify each side of the equation. On the left side, we are given:
[tex]2(x+5)+2[/tex]
First, distribute [tex]2[/tex]:
[tex]2x+10+2[/tex]
Add [tex]10[/tex] and [tex]2[/tex]:
[tex]2x +12[/tex]
On the right side, we are given:
[tex]4x+12-2x[/tex]
So, we subtract [tex]2x[/tex] from [tex]4x[/tex]:
[tex]2x+12[/tex]
Now, we have:
[tex]2x+12=2x+12[/tex]
First, subtract [tex]2x[/tex] from both sides:
[tex]12=12[/tex]
We got, [tex]12=12[/tex], which means [tex]x[/tex] has infinitely many solutions.

Write and solve an inequality to find the values of x for which the perimeter of the rectangle is less than 136.
The diagram says x+4 on the top and x on the side
please help me solve this thanks
Answer: 4x+8<120
x<28
Step-by-step explanation:
As per the statement in the question, the inequality will be 4x + 8 < 136.
What is inequality?Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare the two values. Less than (or less than and equal to), larger than (or greater or equal to), or not similar to signs are used in place of the equal sign in between.
As per the instructions given in the question,
The length (l) of the rectangle = x+4
The width (w) of the rectangle = x
As per the formula of the perimeter, P:
P = 2 (l + w) (i)
Put the values in (i)
P = 2 (x + 4 + x)
P = 2x + 8 + 2x
P = 4x + 8
Then the inequality as per the statement in the question will be,
4x + 8 < 136.
