Answer:
x=66 y=74
Step-by-step explanation:
5.5x + 10y = 1100
x + y = 140
---
y = 140 - x
---
5.5x + 10(140-x) = 1100
5.5x + 1400 - 10x = 1100
-4.5x = -300
x = 66.67
---
x = 66
y = 74
= $1103

Num cinema, há 12 fileiras com 16 poltronas e 15 fileiras com 18 poltronas. O número total de poltronas é
Responder:
462 assentos
Explicação passo a passo:
Dado que :
Número da linha = 12; Número de assentos por fila = 16
Número de linhas = 15; número de assentos por fila = 18
Número total de assentos para as 12 filas:
12 * 16 = 192 assentos
Número total de assentos para as 18 filas:
15 * 18 = 270 assentos
Número total de assentos:
(192 + 270) = 462 assentos

Suppose you draw a card from a well-shuffled deck of 52 cards. What is the probability of drawing a 7 or a queen?
Answer:
[tex]\frac{8}{52}[/tex] = 0.15384615384 = 15.38%
Step-by-step explanation:
There are 4 7 cards and 4 queen cards so,
[tex]\frac{4}{52}[/tex] + [tex]\frac{4}{52}[/tex] = [tex]\frac{8}{52}[/tex]

Find the circumference and the area of circle with diameter 6ft. Use the value 3.14 for pi, and do not round your answers. Be sure to include the correct units in your answers.
Circumference:
Area:
Answer:
Area: 28.26ft², Circumference: 18.84ft
Step-by-step explanation:
Area of a circle: πr²
Circumference of a circle: πd (or 2πr)
Since the diameter is 6ft, then the radius is half of that, which is 3ft. This means that our area is:
πr²
π(3)²
π(9)
9π
9(3.14)
28.26ft²
Our circumference is:
πd
π(6)
6π
6(3.14)
18.84 ft

Answer: -7/10, -0.35, 1/5, 0.95
Step-by-step explanation:
-7/10 = -.7
1/5 = 0.2
Answer:
From least to greatest, the correct order is [tex]-\frac{7}{10}[/tex], -0.35, [tex]\frac{1}{5}[/tex], and 0.95.
Step-by-step explanation:
Since all negative numbers are smaller than positive, you immediately know that [tex]-\frac{7}{10}[/tex] and -0.35 are smaller than [tex]\frac{1}{5}[/tex] and 0.95. The greater the absolute value of a negative number is, the smaller that number is. Because [tex]-\frac{7}{10}[/tex] is -0.7, which has a greater absolute value than -0.35, this means [tex]-\frac{7}{10}[/tex] is the smallest number, and -0.35 is the second smallest number. Since [tex]\frac{1}{5}[/tex] is 0.2 which is smaller than 0.95, the correct order from least to greatest would be [tex]-\frac{7}{10}[/tex], -0.35, [tex]\frac{1}{5}[/tex], and 0.95.

Lucy purchase a swimsuit and a towel. The towel represent 30% of the total cost. If she spent $15.00 on the towel, then what was her purchase total
Answer:
$50
Step-by-step explanation:
Given data
Let the total purchase be x
Hence 30% of x is $15
Let us find the value of x
30/100*x= 15
0.3*x=15
0.3x=15
x= 15/0.3
x= $50
Hence the purchase is $50
Answer:
$50 is the total
Step-by-step explanation:
30% over 100% = 15 over x
then you cross multiply and get:
30x = 1500
you then divide both sides by 30
30 and 30 cross out
1500 ÷ 30 = $50

A teenager has 8 tee shirts, 2 belts, and 5 pairs of jeans. How many different outfits can he wear, assuming that he must wear a belt to keep those pants up and keep that shirt tucked in?
Answer: 80 ways
Step-by-step explanation:
If 8 tee shirts can be worn in 8 ways
similarly for 2 belts = 2 ways
five pair of jeans= 5 ways
so total number of ways=5*2*8=80 ways
A number cube is rolled twice. What is the P (2 and then odd number)?
Answer:
P (2 and then odd number) = [tex]\frac{1}{12}[/tex]
Step-by-step explanation:
Probability refers to chances of occurrence of any event.
A number cube is rolled twice.
Possible outcomes are as follows:
[tex](1,1),(1,2),(1,3),(1,4),(1,5),(1,6)[/tex]
[tex](2,1),(2,2),(2,3),(2,4),(2,5),(2,6)[/tex]
[tex](3,1),(3,2),(3,3),(3,4),(3,5),(3,6)[/tex]
[tex](4,1),(4,2),(4,3),(4,4),(4,5),(4,6)[/tex]
[tex](5,1),(5,2),(5,3),(5,4),(5,5),(5,6)[/tex]
[tex](6,1),(6,2),(6,3),(6,4),(6,5),(6,6)[/tex]
Total number of outcomes = 36
Favorable outcomes include outcomes with 2 and then odd number.
So,
Favorable outcomes are [tex](2,1),(2,3),(2,5)[/tex]
Number of favorable outcomes = 3
Probability is equal to number of favorable outcomes divided by total number of outcomes.
Therefore,
P (2 and then odd number) = Number of favorable outcomes ÷ Total number of outcomes
[tex]=\frac{3}{36}[/tex]
[tex]=\frac{1}{12}[/tex]

Answer:
y = -3/11x + 4/11
Step-by-step explanation:
y2 - y1/ x2 - x1
-1 - 2/ 5 - (-6)
-3 / 11
y = -3/11x + b
-1 = -3/11(5) + b
-1 = -15/11 + b
4/11 = b
