Answer:
a) Quantos estudam Inglês ou Espanhol?
477
b) Quantos fazem espanhol?
210
c) Quantos não estudam nenhuma dessas línguas?
193
Step-by-step explanation:
a) Quantos estudam Inglês ou Espanhol?
Inglês ou Espanhol = Quantidade de alunos que cursam inglês + Quantidade de alunos que cursam espanhol - Quantidade de alunos que cursam inglês e espanhol
= 352 + 210 - 85
= 477
b) Quantos fazem espanhol?
Isso é dado na pergunta como alunos que só aprendem espanhol = Somos informados de que o número de alunos que estudam apenas espanhol = 125
Número de alunos que cursam espanhol = Número de alunos que cursam apenas espanhol + Número de alunos que cursam espanhol e inglês
Número de alunos que fazem espanhol = 125 + 85
= 210 alunos
c) Quantos não estudam nenhuma dessas línguas?
Número total de alunos - (número de alunos que não cursam nenhum dos idiomas) = Número de alunos que cursam inglês + Número de alunos que cursam espanhol - Número de alunos que cursam os dois
= 670 - (número de alunos que não estudam nenhum dos idiomas) = 352 + 210 - 85
= 670 - (número de alunos que não estudam nenhum dos idiomas) = 477
Número de alunos que não cursam nenhum dos idiomas = 670 - 477
= 193 alunos

Answer: C
Step-by-step explanation:
To find b₂, we need to use our algebraic properties to isolate b₂.
[tex]A=\frac{1}{2}h(b_1+b_2)[/tex] [multiply both sides by 2]
[tex]2A=h(b_1+b_2)[/tex] [divide both sides by h]
[tex]\frac{2A}{h} =b_1+b_2[/tex] [subtract both sides by b₁]
[tex]b_2=\frac{2A}{h}-b_1[/tex]
Now, we know that C is the correct answer.
Answer:C

Step-by-step explanation:
What is the equation of the line that passes through (-3, -1) and has a slope of 3/5 ? Put your answer in slope-intercept form. A.y= 3/5x+4/5 B.y= 3/5x-4/5 C.y=-3/5x-4/5
Slope-intercept form: y = mx + b
m = the slope
b = y-intercept.
In this problem,
m = 3/5
b = ?
So far y = 3/5x + b
Let's plug the point (-3, -1) into our slope equation.
-1 = 3/5(-3) + b
Simplify the right side.
-1 = -9/5 + b
Add 9/5 to both sides.
4/5 = b
The equation is: y = 3/5x + 4/5
Answer choice A is correct.

Step-by-step explanation:
If m<2=98, m<3=23, and m<8=70 find the measure of each missing angle
Answer/Step-by-step explanation:
Given:
m<2 = 98,
m<3 = 23,
m<8 = 70
m<1 + m<2 = 180° (linear pair)
m<1 + 98 = 180 (substitution)
m<1 = 180 - 98 (subtracting 98 from each side of the equation)
m<1 = 82°
m<2 + m<3 + m<7 = 180° (sum of angles in a triangle)
121 + m<7 = 180 (substitution)
m<7 = 180 - 121 (subtracting 121 from each side)
m<7 = 59°
m<4 = m<7 (alternate angles are congruent)
Therefore,
m<4 = 59°
m<5 + m<4 + m<3 = 180° (angles on a straight line)
m<5 + 59 + 23 = 180 (substitution)
m<5 + 82 = 180
m<5 = 180 - 82 (subtracting 82 from each side)
m<5 = 98°
m<6 + m<7 + m<8 = 180° (angles on a straight line)
m<6 + 59 + 70 = 180 (subtitution)
m<6 + 129 = 180
m<6 = 180 - 129 (subtracting 129 from each side)
m<6 = 51°
m<9 + m<8 + m<4 = 180° (sum of triangle)
m<9 + 70 + 59 = 180 (substitution)
m<9 + 129 = 180
m<9 = 180 - 129
m<9 = 51°
m<10 + m<9 = 180° (linear pair)
m<10 + 51 = 180° (substitution)
m<10 = 180 - 51
m<10 = 129°

find the value of x so that the figures have the same perimeter
Answer: 7
Step-by-step explanation: For the first figure, 7 + 3 = 10, so the perimeter would be 10 + 10 + 7 + 7, which equals Perimeter = 34. For the other figure, 7 - 4 = 3, so 3 + 14 + 14 + 3 = 34, also. Hope this helps!

Which two binomials in part A didn't have an equivalent factored form? What made these expressions different from the
three that you could factor?
The two that didn’t have equivalent factored forms were x^2+16 and 16x^2+9
Answer:
The binomials 16x2 + 9 and x2 + 16 didn’t have an equivalent factored form. Both are sums of perfect squares instead of differences.

What is the absolute value of 3 2/3
Answer:
-3 2/3
Step-by-step explanation:
If the number is positive and they are asking for the absolute value it's always going to be negative of the number they are asking you for the absolute value of. Same thing if it was a negative 3 2/3 then the absolute value of -3 2/3 would be positive 3 2/3.
I hope this helped! <3
Answer: 3.66..
Step-by-step explanation: absolute value is the value of the number from the number 0 on the number line so, 3 ⅔ in decimals is 3.66... so the answer is 3.66... because that is how much the number is if you are counting from 0.

A vendor at a baseball game sells boxes of popcorn and bags of pretzels.
• A customer buys 2 boxes of popcorn and 1 bag of pretzels for $6.75.
• Another customer buys 1 box of popcorn and 2 bags of pretzels for $6.00.
Each bag of pretzels costs $
Answer:
Each bag of pretzels costs $1.75
Step-by-step explanation:
Let the cost of 1 box of popcorn be $x
Let the cost of 1 bag of pretzel be $y
_______________________________________
A customer buys 2 boxes of popcorn and 1 bag of pretzels for $6.75.
cost of 2 box of popcorn =2*$x = $2x
sum of cost 2 boxes of popcorn and 1 bag of pretzels in terms of x and y
2x + y = 6.75 equation A
__________________________________
Another customer buys 1 box of popcorn and 2 bags of pretzels for $6.00
cost of 2 box of pretzel =2*$y = $2y
sum of cost of 1 box of popcorn and 2 bags of pretzels in terms of x and y
x + 2y = 6 equation B
x = 6 - 2y
substituting this value of x in equation A
2(6 - 2y) + y = 6.75
=> 12 - 4y + y = 6.75
=> -3y = 6.75 - 12 = -5.25
=> y = -5.25/-3 = 1.75
Thus, Each bag of pretzels costs $1.75

Find all roots.
11) x^3 + 6x² + 5x = 0
Answer:
x=0
x=-1
x=-5
Step-by-step explanation:
To find the roots, we set the equation equal to zero and factor.
x(x²+6x+5)=0 [factor]
x(x+1)(x+5)=0 [set each factor equal to 0]
x=0
x+1=0 [subtract both sides by 1]
x=-1
x+5=0 [subtract both sides by 5]
x=-5
Now, we have found three roots, x=0, x=-1, x=-5.
