23% more than the number last week. This week, there were 7134 new cases. How many new cases were there last week?
Answer:
Number of cases sold last week= 31,017 cases
Step-by-step explanation:
Giving the following information:
Increase in sales= 23%
This week, there were 7,134 new cases.
If 7,134 cases represent the 23%, then we need to use the rule of three:
Number of cases sold last week= (7,134*100)/23
Number of cases sold last week= 31,017 cases

Which expression is a factor of 9r^2 - 4r + 1?
F 3r-1
G r- 1
H- 9r- 1
J- There are no real factors.
9514 1404 393
Answer:
J- There are no real factors.
Step-by-step explanation:
For quadratic ax^2 +bx +c, the discriminant is ...
d = b^2 -4ac
d = (-4)^2 -4(9)(1) = 16 -36 = -20
When the discriminant is negative, there are no real factors.
Answer: there are no real factors
Step-by-step explanation:
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]
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

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]

Indicate the equation of the given line in standard form.
The line that contains the point Q( 1, -2) and is parallel to the line whose equation is
y - 4 = 2/3 (x - 3)
Answer:
The equation of the line is;
3y = 2x-8
Step-by-step explanation:
Firstly, we need the to get the slope of the given line
To do this, we will write the equation of the line in the standard form
the standard form
is;
y = mx + b
where m is the slope and b is the y-intercept
y -4 = 2/3(x-3)
y -4 = 2x/3 - 2
y = 2x/3 -2 + 4
y = 2x/3 + 2
with respect to the given equation, the slope of the line is 2/3
Mathematically, when two lines are parallel, the slopes of the line are equal
So now, we want to find the equation of the line that has a slope of 2/3 and passes through the point (1,-2)
so;
y = 2x/3 + b
So substitute the values of (1,-2)
1 for x and -2 for y
-2 = 2/3(1) + b
-2 = 2/3 + b
b = -2 - 2/3
b = (-6-2)/3 = -8/3
So the equation of that line is;
y = 2/3x - 8/3
Multiply through by 3
3y = 2x - 8

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

put them from least to greatest
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.
