1. Un examen de Matemáticas ha sido aprobado por 6/9 de los estudiantes. Al resto de los estudiantes le toca repetir el examen. Si el grupo está compuesto por 45 estudiantes, ¿cuántos estudiantes deben repetir dicho examen?
ayudenme mañana tengo q hacer el exameeeeeeeeen
Answer:
15 students
Step-by-step explanation:
The fraction of students who will repeat the exam is:
[tex]1-\frac{6}{9}[/tex]
=[tex]\frac{9}{9} -\frac{6}{9} =\frac{3}{9}[/tex]
simplified is:
[tex]\frac{1}{3}[/tex]
Extract this fraction of 45:
[tex]45(\frac{1}{3} )=\frac{45}{3} =15[/tex]

Answer:
2x - y - 5z
Step-by-step explanation:
Given
-[z - 3y - (3x - z - 2y) + 3z + 2y] - x =
Distribute the subtraction into the ()
-[z - 3y -3x + z + 2y + 3z + 2y] - x =
Move the terms around, keeping the sign with the term
-[z + z + 3z - 3y + 2y + 2y - 3x] - x =
Combine like terms
-[2z + 3z - 3y + 2y + 2y - 3x] - x =
-[5z - 3y + 2y + 2y - 3x] - x =
-[5z - y + 2y - 3x] - x =
-[5z + y - 3x] - x =
Distribute the subtraction into the []
-5z - y + 3x - x =
Combine like terms
- 5z - y + 2x
Reorder:
2x - y - 5z

Please solve this equation by simplifying
Answer:
Step-by-step explanation:
[tex]\sqrt{82}=9.06[/tex]
10² ÷ 5 *√82 - π*2 = 100÷ 5 *9.06 - 3.14*2
= 20 *9.06 - 3.14*2
= 181.2 - 6.28
= 174.92
or
10² ÷5 *√82 - π*2 = 100÷5 *√82 - 2π
= 20√82-2π
Answer:
[tex]10^2 \div 5 \times \sqrt{82} - \pi \times 2[/tex]
Using order of operations, we need to carry out the exponents first:
[tex]10^2=10 \times 10=100[/tex]
[tex]\implies 100 \div 5 \times \sqrt{82} - \pi \times 2[/tex]
Then we need to carry out multiplication and division (it doesn't matter in which order):
[tex]\implies 100 \div 5 \times \sqrt{82} - \pi \times 2[/tex]
[tex]\implies 20\times \sqrt{82} - 2\pi[/tex]
[tex]\implies 20\sqrt{82} - 2\pi[/tex]
Unless you have been given an approximation for pi, it cannot be simplified any further.
[tex]20\sqrt{82} - 2\pi=1.748245175...[/tex]

The rectangular floor of a classroom is 35 feet in length and 30 feet in width. A scale drawing of the floor has a length of 7 inches. What is the area, in square inches of the floor in the scale drawing?
Divide the lengths to find the scale :
35/7 = 5
Now divide the width by the scale to get the scaled width:
30/5 = 6 inches
the scaled drawing is 7 x 6
area of scaled drawing = 7 x 6 = 42 square inches

Step-by-step explanation:
4.8(x)+1.2(y)=2.4
9.6 + 1.2y = 2.4
subtract 9.6 from both sides
1.2y = - 7.2
divide by 1.2 on both sides
y = -6

Solve x2 8x = 33 by completing the square. Which is the solution set of the equation? {–11, 3} {–3, 11} {–4, 4} {–7, 7}.
The solution set of the given quadratic equation using factorization will be {-3,11}
Given equation is
[tex]x^{2} -8x-33 = 0[/tex]
What is a quadratic equation?The polynomial equation whose highest degree is two is called a quadratic equation. The equation denoted by ax² + bx + c = 0, where a is non-zero.
Let us calculate the roots by factorization
[tex]x^{2} -11x+3x-33=0[/tex]
[tex]x(x-11)+3(x-11)=0[/tex]
[tex](x-11) (x+3)=0[/tex]

Read the selection. Answer each question about judgment. Try to give a Bible verse to back up your answer.
Ann's parents are not Christians. They forbid Ann to visit her Christian friends.
Do you think Ann should obey her parents? Why or why not?
Answer:
No
Step-by-step explanation:
It is very healthy for someone to be with a community of likeminded individuals although the bible indeed supports obedience to one's parents, that's only in affect unless what they are telling you to commit sinful acts. In this case Ann's parents are forbidding her to see her Chirstian friends which is sinful speaking how Christians are considered God's people. Even though God expects you to honor your parents, you cannot honor the dishonorable.
Leviticus 19:3 "Every one of you shall revere his mother and his father, and you shall keep My Sabbaths; I am the LORD your God."
Colossians 3:21 "Fathers, do not provoke your children, lest they become discouraged."
Romans 12:18 "If possible, so far as it depends on you, live peaceably with all."
God is speaking during times when his people were raised by good parents who have the fear of the Lord in their hearts. In these times they're many "bad" parents who don't honor the Lord's teachings which they themselves should not be honored.

Find the distance between two points: (5,3),(8,5)
Answer:
[tex] \displaystyle\boxed{\rm \: Distance= \underline{\underline{\sqrt{13}}}} [/tex]
OR in Decimal,
[tex] \boxed{\rm \: Distance=\underline{\underline{3.605}}}[/tex]
Step-by-step explanation:
Given:
Two points, that is (5,3) & (8,5)
To Find:
The Distance of the two given points
Solution:
To Find the distance between two points, we will use the distance formula, i.e. :
[tex] \boxed{ \rm \: Distance = \sqrt{(x_2 - x_1) {}^{2} + (y_2 - y_1) {}^{2} } }[/tex]
According to the Question,
[tex] \rightarrow \: \rm \: x_2 = 8[/tex]
[tex]\rightarrow \: \rm \: x_1 = 5[/tex]
[tex]\rightarrow \: \rm \: y_2 = 5[/tex]
[tex]\rightarrow \: \rm \: y_1 = 3[/tex]
Now Substitute the values on the formula of Distance and then Simplify:
[tex] \rm \: Distance= \sqrt{(8 - 5 )^{2} + (5 - 3) {}^{2} } [/tex]
[Follow PEMDAS rule while simplifying]
[tex] \rm \: Distance= \sqrt{3 {}^{2} + 2 {}^{2} } [/tex]
[tex] \rm \: Distance= \sqrt{(3 \times 3) + (2 \times 2)} [/tex]
[tex] \rm \: Distance= \sqrt{9 + 4} [/tex]
[tex] \rm \: Distance= \sqrt{13} [/tex]
[tex] \rm \: Distance= {3.605} [/tex]
Hence, the distance between the two given points would be [tex]\sqrt{13}[/tex] or [tex] 3.605 [/tex].

A child casts a shadow 1.3 m long. The distance from the top of the child’s head to the end of the shadow is 1.9 m. To the nearest centimetre, how tall is the child?
Answer:
Height of the boy is 1.4 m and casts a shadow of 1.2 m
At the same time, a building casts a shadow of 5.4 m and suppose height of the building is x m
Then ratio of their heights and shadows are in proportion
⟹1.4x=1.25.4
⟹x=1.21.4×5.4
⟹x=6.3
Hence, height of the building is 6.3 m.

Mr. White tutors one of his students after school.
The job pays $250 for ten hours of work.
He needs to make $750.
How many hours of tutoring would Mr. White need to work?
Answer:
30 hours of work
Step-by-step explanation:
Ok if Mr. White works 10 hours he gets 250$
250+250=500$
10 + ㅤ10 = 20 hours
500+250=750
20ㅤ+ 10 = 30
so this means he will have to work 30 to get 750$
Answer:
30 hours
Step-by-step explanation:
If 10 hours = $250
Than you can divide 750/250 and you’ll get 3. Multiply 3 by 10 ( 3 • 10 ) and you’ll get 30 hours.

SOLVE, SUBTRACT 2x
6=3x-9 THEN ADD 9
15=3x THEN divide by 3
5=x
Plug in x to either side 2(5)+6, to get side length of 16
Then area of a rectangle is lengthxwidth=AREA
