André e Bruno foram a uma lanchonete e compraram lanches e sorvetes iguais. Bruno comprou 2 lanches e 1 sorvete e pagou R$21,00. Já André comprou 3 lanches e 2 sorvetes, pagando R$33,00. Qual era o preço, em reais, de cada lanche que André e Bruno compraram nessa lanchonete? R$5,00. R$9,00. R$10,50. R$10,70.
Answer:
the price of each snack be R $9.00
Step-by-step explanation:
Let us assume the snack be x
And, the ice cream be y
Now according to the question
2x + y = $21
And,
3x + 2y = $33
Now multiply by 2 in equation 1
So,
4x + 2y = $42
3x + 2y = $33
x = 9
Hence, the price of each snack be R $9.00
Find the answer what is X?
Answer:
[tex]x = 6[/tex]

The scatter plot shows the amount of sleep Aria got the night before a test and her test scores. Use the y-intercept, (0, 62), and the point (6, 80) from the line on the scatter plot. What is the equation of the trend line? (*Note: Enter your response as an equation in y=mx+b form. Enter no spaces & use only lower-case letters. Ex: y=10x+5 ) *
Answer:
y = 3x + 62
Step-by-step explanation:
Trend line equation in the form :
y = mx + b
m = slope
b = intercept
Using the points :
(0, 62) ; (6, 80)
Slope, m = Rise / Run = (y2-y1) / (x2 - x1)
y2 = 80 ; y1= 62 ; x2 = 6 ; x1 = 0
m = (80 - 62) / (6 - 0)
m = 18 / 6
m = 3
Intercept, b = value of y when x = 0
(0, 62) ; hence, b = 62
y = 3x + b
y = 3x + 62

Solve the right triangle. Round your answers to the nearest tenth.
Answer:
Step-by-step explanation:
The sum of the three angles in a triangle is [tex]\ang{180}[/tex].
We know that a right angle is [tex]\ang{90}[/tex], and we are given another angle that is [tex]\ang{50}[/tex], so that means that angle [tex]B[/tex] is:
[tex]B + 50 + 90 = 180[/tex]
[tex]B + 140 = 180[/tex]
[tex]B = 40[/tex]
To find side length [tex]a[/tex], we can use the [tex]sin[/tex] function:
[tex]sin(\ang{50}) = \frac{a}{20}[/tex]
[tex]20 * 0.766 = a[/tex]
[tex]a = 15.32[/tex]
To find side length [tex]b[/tex], we can again use the [tex]sin[/tex] function:
[tex]sin(\ang{40}) = \frac{b}{20}[/tex]
[tex]20 * 0.643= b[/tex]
[tex]b = 12.86[/tex]

Michael buys a car for $14, 999. The tax rate is 6%. What is the total purchase price of the car?
Answer:
15898.94
Step-by-step explanation:
First find the amount the tax is
6% = 0.06
14999 * 0.06 = 899.94
Add the amount of tax to the total amount of the net price (the price before tax)
14999 + 899.94 = 15898.94

64 cm 3
125 cm 3
8 cm 3
100 cm 3
Answer:
100 cm³
Explanation

Answer:
Answer would be 18
Step-by-step explanation:
Dilation simply means to get bigger or larger. So in this case from point Y to point z is 6. We would take 6 and dilate it with a factor of 3 (which also means to multiply). When you multiply 6*3 you will end up with 18, and that is your answer
