Answer:
80
Step-by-step explanation:
The total angles in a triangle will have to add up to 180 degrees. Since these two have the same angles, we know that a=e and b=d. We know angle a is 30 and angle c is 70 which equals 100. 180-100 is 80, therefore angle d= 80 degrees.

52% of the total number of students in a school are boys. If there are 260 boys,
Question:
52% of the total number of students in a school are boys. If there are 260 boys, how many students are there in total? how many of them are girls?
Answer and Step-by-step explanation:
The total amount of students is 500.
Yo get this by dividing 260 by 52%, or 0.52
Now, we know 260 is the amount of boys, so to find the amount of girls, we subtract 260 from 500.
500 - 260 = 240.
There are 240 students that are girls.
This also means that 48% of the total number of students in a school are girls.

What is the length of the leg
Answer:
The length of the leg is 8.7
Step-by-step explanation:
Formula:
a = √(c² - b²)
Substitute 9 for c and 2 for b:
a = √(9² - 2²)
a = √(81 - 4)
a = √77
a = 8.77496438739

Why should Emily use a wire to connect point 2 to point 4? A) Metal wire is always expensive to work with. B) Metal is a good insulator of electricity. C) Metal wire is a good conductor of electricity. D) Metal is an inexpensive material to work with.
Answer:
c.) Metal wire is a good conductor of electricity.
Step-by-step explanation:

"Metals are an excellent conductor of electricity and heat because the atoms in the metals form a matrix through which outer electrons can move freely. Instead of orbiting their respective atoms, they form a sea of electrons that surround the positive nuclei of the interacting metal ions."

La suma dels quadrats de tres nombres naturals consecutius i múltiples de 3 és igual a 450. Planteja una equació de segon grau i calcula els tres nombres.
Answer:
The 3 numbers are 9, 12, and 15.
Step-by-step explanation:
I will answer in English, below the answer you can see a translation in Catalan.
This can be translated to:
The sum of the squares of three consecutive and multiple natural numbers of 3 is equal to 450. Pose a quadratic equation and calculate the three numbers.
First, a multiple of 3 can be written as:
3*n
The consecutive multiple of 3 is:
3*n + 3
The consecutive multiple of 3 is:
3*n + 3 + 3
Then the sum of their squares is:
(3*n)^2 + (3*n + 3)^2 + (3*n + 6)^2
And we know that this is equal to 450, then we need to solve the equation:
(3*n)^2 + (3*n + 3)^2 + (3*n + 6)^2 = 450
let's solve this:
9*n^2 + (9*n^2 + 2*(3*n)*3 + 9) + (9*n^2 + 2*(3*n)*6 + 36) = 450
27*n^2 + 54*n + 45 = 450
we can write this as:
27*n^2 + 54*n + 45 - 450 = 0
27*n^2 + 54*n - 405 = 0
The solutions of this equation are given by the Bhaskara's formula, and the solutions are:
[tex]n = \frac{-54 \pm \sqrt{54^2 -4*27*(-415)} }{2*27} = \frac{-54 \pm 216 }{54}[/tex]
we know that our numbers are naturals, then the numbers are positives, which means that we only care for the positive solution of n, which is:
n = (-54 + 216)/54 = 3
Then the 3 numbers are:
3*n = 3*3 = 9
(3*n + 3) = (3*3 + 3) = 12
(3*n + 6) = (3*3 + 6) = 15
In Catalan:
En primer lloc, es pot escriure un múltiple de 3 com:
3 * n
El múltiple consecutiu de 3 és:
3 * n + 3
El múltiple consecutiu de 3 és:
3 * n + 3 + 3
Llavors, la suma dels seus quadrats és:
(3 * n) ^ 2 + (3 * n + 3) ^ 2 + (3 * n + 6) ^ 2
I sabem que això és igual a 450, llavors hem de resoldre l’equació:
(3 * n) ^ 2 + (3 * n + 3) ^ 2 + (3 * n + 6) ^ 2 = 450
resolem això:
9 * n ^ 2 + (9 * n ^ 2 + 2 * (3 * n) * 3 + 9) + (9 * n ^ 2 + 2 * (3 * n) * 6 + 36) = 450
27 * n ^ 2 + 54 * n + 45 = 450
podem escriure això com:
27 * n ^ 2 + 54 * n + 45 - 450 = 0
27 * n ^ 2 + 54 * n - 405 = 0
Les solucions d’aquesta equació vénen donades per la fórmula de Bhaskara, i les solucions són:
[tex]n = \frac{-54 \pm \sqrt{54^2 -4*27*(-415)} }{2*27} = \frac{-54 \pm 216 }{54}[/tex]
sabem que els nostres nombres són naturals, aleshores els nombres són positius, cosa que significa que només ens importa la solució positiva de n, que és:
n = (-54 + 216) / 54 = 3
Llavors els 3 nombres són:
3 * n = 3 * 3 = 9
(3 * n + 3) = (3 * 3 + 3) = 12
(3 * n + 6) = (3 * 3 + 6) = 15
()) A rectangular piece of paper has a perimeter of 22 inches and an area of 28 square
inches. What are the dimensions of the paper?
Given:
Perimeter of a rectangular paper = 22 inches.
Area of the rectangular paper = 28 square inches.
To find:
The dimensions of the rectangular paper.
Solution:
Let l be the length and w be the width of the rectangular paper.
Perimeter of a rectangle is:
[tex]P=2(l+w)[/tex]
Perimeter of a rectangular paper is 22 inches.
[tex]2(l+w)=22[/tex]
[tex]l+w=\dfrac{22}{2}[/tex]
[tex]l=11-w[/tex] ...(i)
Area of a rectangle is:
[tex]A=lw[/tex]
Area of the rectangular paper is 28 square inches.
[tex]28=lw[/tex]
Using (i), we get
[tex]28=(11-w)w[/tex]
[tex]28=11w-w^2[/tex]
[tex]w^2-11w+28=0[/tex]
Splitting the middle term, we get
[tex]w^2-7w-4w+28=0[/tex]
[tex]w(w-7)-4(w-7)=0[/tex]
[tex](w-7)(w-4)=0[/tex]
Using zero product property, we get
[tex](w-7)=0\text{ and }(w-4)=0[/tex]
[tex]w=7\text{ and }w=4[/tex]
If [tex]w=7[/tex], then by using (i)
[tex]l=11-7[/tex]
[tex]l=4[/tex]
If [tex]w=4[/tex], then by using (i)
[tex]l=11-4[/tex]
[tex]l=7[/tex]
Therefore, the dimensions of the paper are either [tex]7\times 4[/tex] or [tex]4\times 7[/tex].
Find the volume of the figure
Answer:
132 yd³
Step-by-step explanation:
To find the volume of a triangular prism, use this equation: V = (1/2bh) * h
V = (1/2(11 * 4)) * 6
Step 1: Multiply 11 by 4 to get 44.
V = (1/2(44)) * 6
Step 2: Multiply 1/2 by 44 to get 22.
V = 22 * 6
Step 3: Multiply 22 by 6 to get 132.
V = 132
The volume of the figure is 132 yd³.

What is the lateral and surface area?
Answer:
L = 324 cm²
S = 359.1 cm²
Step-by-step explanation:
Lateral surface area of a triangular prism is given by,
Lateral surface area = Perimeter of the triangular base × Height
= (9 + 9 + 9)×12
= 27 × 12
= 324 cm²
Surface area area of the triangular prism = Lateral area of the prism + Area of the triangular bases
= 324 + [tex]\frac{1}{2}(Base)(Height)[/tex]
= 324 + [tex]\frac{1}{2}(9)(7.8)[/tex]
= 324 + 35.1
= 359.1 cm²
Solve this system using substitution: y=5x and 7x-3y=32
Answer:
x = -4 and y = -20
Step-by-step explanation:
y = 5x and 7x - 3y = 32
→ Substitute y = 5x into 7x - 3y = 32
7x - 15x = 32
→ Simplify
-8x = 32
→ Solve
x = -4
→ Substitute x = -4 into y = 5x
5 × -4 = -20
