442 m - x cm
Hence,
[tex]\displaystyle\\x=\frac{442*82,4}{412} \\\\x=\frac{442*82.4}{82.4*5} \\\\x=\frac{442}{5}=\\\\x=\frac{88,4*5}{5}=\\\\x=88,4\ cm[/tex]
The table below shows the masses of some pears in a crate. If one of the pears is chosen at random from the crate, what is the probability that it has a mass of more than 120 g? Give your answer as a fraction in its simplest form.
PLS
The probability that it has a mass of more than 120 g is 13/40.
What is probability?Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we might discuss the likelihood or likelihood of several outcomes. Statistics is the study of occurrences that follow a probability distribution.
Given,
frequency = 5 9 13 7 6
sum of frequency = 40
P(120<m<=180) = 13/40
P(180<m<=240) = 7/40
P(240<m<=300) = 6/40
Probability that it has a mass of more than 120 g = [P(120<m<=180) + P(180<m<=240) + P(240<m<=300) ]
⇒ 13/40 + 7/40 + 6/40
= 26/40
= 13/20

Evaluate (1.28 × 105) + (1. 13 × 10³). Express the result in scientific notation.
The value of the expression in scientific notation is 1.2913 * 10^5
How to evaluate the expression?The expression is given as:
(1.28 × 105) + (1. 13 × 10³)
Rewrite properly as
(1.28 × 10^5) + (1. 13 × 10^3)
Express 10^3 as 10^-2 * 10^5
So, we have
(1.28 × 10^5) + (1. 13 × 10^3) = (1.28 × 10^5) + (1. 13 × 10^-2 * 10^5)
Factor out 10^5
So, we have:
(1.28 × 10^5) + (1. 13 × 10^3) = (1.28 + 1. 13 × 10^-2) * 10^5
This gives
(1.28 × 10^5) + (1. 13 × 10^3) = (1.28 + 0.0113) * 10^5
Evaluate the sum
(1.28 × 10^5) + (1. 13 × 10^3) = 1.2913 * 10^5

y = 5x - 3
10x - 2y = 7
Answer:
No solution
Step-by-step explanation:
First I plugged the value of y into the equation 10x-2y=, which gave me
10x- 2(5x - 3) = 7. Then you can distribute the -2 into the parenthesis giving you 10x - 2(5x)(-2 x -3) = 7. This leaves us with 10x- 10x + 6 = 7, because two negatives multiplied together form a positive. Now you subtract six from both sides to keep it equal, and you're left with 10x-10x= 1. This gives you 0= 1, which is not possible, so there is no solution.
We can check our work by putting 10x -2y= 7 into y=mx+b format, by subtracting 10x from both sides, leaving you with -2y = -10x+ 7. then you can divide out the -2, giving you y= 5x+ 7/5. Notice how the slopes in both our equations are 5x. This means that they are a group of parallel lines, bc they both stay at the same rate, despite having different y-intercepts or starting points.

The table shows the items that come in an appetizer sampler at a family restaurant.
Small Sampler
4 chicken wings
2 loaded potato skins
2 mozzarella sticks
8 pretzel bites
The restaurant wants to create a larger appetizer sampler to accommodate larger groups of customers. They also
want to limit the number of pretzel bites to 20. If the ratio remains the same, how many mozzarella sticks will be in
the larger sampler?
The number of mozzarella sticks that will be in the larger sample will be 5.
How many mozzarella sticks will be in the larger sample?Ratio expresses the relationship between two or more numbers. It shows the number of times that one value is contained within other value(s). The sign used to express ratios is :.
The first step is to determine the ratio of mozzarella sticks to pretzel bites in the smaller sample. This can be done by dividing the quantity of mozzarella sticks by the number of pretzel bites.
Number of mozzarella sticks / number of pretzel bites = 2 : 8 or 1 : 4.
Now, divide the number of pretzel bites in the larger sample by the ratio of mozzarella sticks and pretzel bites in the smaller sample.
The ratio of mozzarella sticks in the larger sample = 20 / 4 = 5

The area of rectangle at left is 30 cm²The area of rectangle at the bottom of the rectangular prism is 10 cm².The total surface area (TSA) of rectangular prism is 230 cm²
Step-by-step explanation:
Given that
Height = 15 cmWidth = 2 cmLength = 5 cmThe area of the rectangle in front = 15x5 = 75cm²To find
The area of the rectangle on the left side of the rectangular prism.The area of the rectangle at the bottom of the rectangular prismThe total surface area (TSA) of the rectangular prism.So, according to the question
Let's assume,
height = h = 15cm
length = l = 2cm
width = w = 5cm
So, from question,
Area of rectangle in front = 15 cm x 5 cm
That's mean
Rectangle in front have h = 15cm and l = 5cm.
We know the width from question w = 2cm.
So,
Area of the rectangle to the left = h x w
= 15 x 2
= 30 cm²
Also,
There is no height to the rectangle at the bottom.
So, l and w make up the bottom rectangle.
Now,
the area of rectangle at the bottom = l x w
= 5 x 2
= 10 cm²
Now,
The total surface area (TSA) of the rectangular prism = 2(lw + wh + lh)
= 2 ( 75 + 10 + 30)
= 2 x (115)
= 230cm²
So,

You deposit $3500 in an account that
earns 4% simple interest. How long will
you have to leave the money in the acount
to earn $350 interest?
Answer:
2years 6 months
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4%/100 = 0.04 per year.
I = P × R × T/100
Solving our equation:
$350 = $3500 × 4 × T /100
Let's solve your equation step-by-step.
350=(3500)(4)t/100
Step 1: Multiply both sides by 100.
350=(3500)(4)t/100
(350)*(100)=((3500)(4)t/100)*(100)
35000=(3500)(4)t
Step 2: Simplify both sides of the equation.
35000=14000t
Step 3: Flip the equation.
14000t=35000
Step 4: Divide both sides by 14000.
14000t/14000=35000/14000
t=5/2
t = 2.5 years
2.5 years = 2years 6 months

Take the vertical height
Smaller figure = 4
