Answer:
2 unique triangles
Step-by-step explanation:
We can only form two triangles
Since two of the sides are equal, we can form two isosceles triangles
The first one will have 10, 10 , the last side, then 40, 70 , 70 as the internal angles
Just note that the angles must add up to be 180 and that there are two equal angles as we are dealing with an isosceles triangle
The second form is 10, 10 , 40 , 40 and 100
Here, we have the 40 on the sides of the base of the isosceles triangle with the measure 100 being the last angle
The number of unique triangles that can be formed with he given parameters are; 2
We are told that;
Two side lengths of the triangle = 10 cm
One angle = 40°
This means the that the triangle can be an isosceles triangle.Now, the two equal angles could be 40° each.
Sum of angles in a triangle = 180°Thus;
Third angle of the triangle = 180 - 2(40) = 100°
Now,if we assume that the 40° is not the equal angle, then it means that the equal angle will be;(180 - 40)/2 = 140/2
>> 70°
Thus, we can make 2 unique isosceles triangles.

Mario's Pizza just received two big orders from customers throwing parties. The first customer, Amelia, bought 10 regular pizzas and 1 deluxe pizza and paid $133. The second customer, Jaden, ordered 7 regular pizzas and 9 deluxe pizzas, paying a total of $284. What is the price of each pizza?
Answer:
The regular costs 11 dollars each while the deluxe cost 23 each.
Step-by-step explanation:
You need to setup two equations.I used two variable for the prices of the types of pizzas because they are unknown.I used x for the cost of regular and y for the cost of deluxe.The equation I did are 10x+y=133 and 7x+9y=284.You need to solve one equation only.I solved the first one.
A piece of wire is 76cm long. It is cut into two unequal parts and each part is bent into a square. The sum of the areas of the two squares is 205cm². Find the length of the shorter part of the wire.
Answer:
The length of the shorter part of the wire is 24 centimeters.
Step-by-step explanation:
Let [tex]L[/tex] the total length of the piece of wire, where [tex]L-x[/tex] and [tex]x[/tex] are the perimeters of the greater and lesser squares. All lengths are measured in centimeters. Since squares have four sides of equal length, the side lengths for the greater and lesser squares are [tex]\frac{L-x}{4}[/tex] and [tex]\frac{x}{4}[/tex]. From statement we find that the sum of the areas of the two squares ([tex]A[/tex]), measured in square centimeters, is represented by the following expression:
[tex]A = \left(\frac{L-x}{4} \right)^{2}+\left(\frac{x}{4} \right)^{2}[/tex] (1)
And we expand this polynomial below:
[tex]A = \frac{L^{2}-2\cdot L\cdot x +x^{2}}{16} + \frac{x^{2}}{16}[/tex]
[tex]A = \frac{L^{2}-2\cdot L\cdot x +2\cdot x^{2}}{16}[/tex]
[tex]2\cdot x^{2}-2\cdot L\cdot x +L^{2}-16\cdot A = 0[/tex] (2)
If we know that [tex]L = 76\,cm[/tex] and [tex]A = 205\,cm^{2 }[/tex], then the length of the shorter part of the wire is:
[tex]2\cdot x^{2}-152\cdot x +2496 = 0[/tex]
By the Quadratic Formula, we determine the roots associated with the polynomial:
[tex]x_{1} = 52\,cm[/tex], [tex]x_{2} = 24\,cm[/tex]
The length of the shorter part of the wire corresponds to the second root. Hence, the length of the shorter part of the wire is 24 centimeters.

Lynn has a box of crayons.
4/9 of the crayons are blue
65% of the remaining crayons are red.
The other 14 crayons are yellow.
How many crayons are in the box altogether?
Answer:
There are 72 crayons in the box
Step-by-step explanation:
Fractions
To solve this problem we'll manage numbers as fractions to keep the precision up to the end of it.
Lynn has a box of crayons. It's given 4/9 of the crayons are blue. The remaining crayons are:
[tex]1-\frac{4}{9}=\frac{5}{9}[/tex]
From that portion, 65% are red, or equivalently, 35% are yellow.
We write 35% as a fraction:
[tex]\displaystyle 35\%=\frac{35}{100}=\frac{7}{20}[/tex]
Thus, the portion of yellow crayons is:
[tex]\displaystyle \frac{7}{20}\cdot \frac{5}{9}=\frac{7}{36}[/tex]
This fraction of x crayons is equal to 14, thus:
[tex]\displaystyle x=\frac{14}{\frac{7}{36}}=14\cdot\frac{36}{7}[/tex]
x = 72
There are 72 crayons in the box

Answer: 16π
Step-by-step explanation:
First, solve for total area:
A = πr^2
A = π(8^2) = 64π
Then, find 1/4 of the area of the whole (since this is only a quarter circle)
A/4 = (64π)/4 = 16π
Mike paid $32 for a sult Jacket that had been marked down 40% from its original price, What was the original price.
Answer:
The answer is $44.80
Step-by-step explanation: First, you need to find the how much 40% of $32 is:
32 x .40 = 12.80
Then, you add 12.80 to $32.
$32 + $12.80 = $44.80
Answer: 44.8$
Step-by-step explanation:
What you have to do is find 40% of 32. (it is 12.8) add 12.8 to 32. You get 44.8

please show steps and explain how so i can understand
Answer:
21/8
Step-by-step explanation:
okay so what we have to do is called flip n' multiply, so we leave the first fraction the way it is and the second one, we flip. so instead of 3/9, it would be 9/3. now we just do 7/8 times 9/3 to get 63/24 which I believe will be simplified to 21/8
Answer:
Seven eighths divided by three ninths is equal to twenty-one eights.
Step-by-step explanation:
The easiest way to divide one fraction by another is to simply multiply the first one by the second one. It's that easy:
[tex]\frac{7}{8} \div \frac{3}{9}[/tex]
is exactly the same as:
[tex]\frac{7}{8} \times \frac{9}{3}[/tex]
Which we can then solve by multiplying the numerators by each other and multiplying the denominators by each other
[tex]\frac{7}{8} \times \frac{9}{3}\\\\ = \frac{7 \times 9}{8 \times 3} \\\\ = \frac{63}{24} \\\\ = \frac{21}{8}[/tex]
Another way you can solve it is by noting that in the second number, both the numerator and denominator are divisible by 3, which gives a way to simplify before doing the division:
[tex]\frac{7}{8}\div \frac{3}{9}\\\\= \frac{7}{8}\div \frac{1}{3}\\\\= \frac{7}{8}\times \frac{3}{1}\\\\= \frac{7}{8}\times 3\\\\= \frac{21}{8}[/tex]
