Answer:
292.4
Step-by-step explanation:
Answer:
292.4
Step-by-step explanation:
Use the mean formula: sum of elements / number of elements
Plug in the numbers:
(300 + 222 + 285 + 310 + 345) / 5
1462 / 5
= 292.4
So, the mean is 292.4
ABCF is a rectangle.
CDEF is a trapezium.
AE is a straight line.
AB = 9cm, AE = 11cm, DE = 5cm.
The perimeter of rectangle ABCF is 28 cm.
Calculate the area of trapezium CDEF.
The area of trapezium CDEF will be 42 cm².
What is surface area?The quantity of space enclosing a three-dimensional shape's exterior is its surface area.
In other meaning, if we say side square then it is an area of the square but for a cuboid, there are 6 faces so the surface area will be external to all 6 surfaces area.
The perimeter of the rectangle ABCF is 28 cm.
Let's say BC = FA = x
Perimeter = AB + BC + CF + FA
Perimeter = 9 + x + 9 + x
Perimeter = 18 + 2x
2x + 18 = 28
x = 5 cm
Now,
Area of trapezium = (1/2) × sum of parallel distance × perpendicular distance.
Area of trapezium = (1/2) × (5 + 9) × 6
Area of trapezium = 42 cm²
Hence "The area of trapezium CDEF will be 42 cm²".

Consider the line y = - 4x +3,
Find the equation of the line that is parallel to this line and passes through the point (2, -3).
Answer:
y = -4x + 5 {slope-intercept form}Step-by-step explanation:
y=m₁x+b₁ ║ y=m₂x+b₂ ⇔ m₁ = m₂
{Two lines are parallel if their slopes are equal}
y = - 4x + 3 ⇒ m₁ = -4 ⇒ m₂ = -4
The point-slope form of the equation of a line it's y - y₁ = m(x - x₁), where m is the slope and (x₁, y₁) is the point the line passing through.
m = -4
(2, -3) ⇒ x₁ = 2, y₁ = -3
point-slope form:
y - (-3) = -4(x - 2)
y + 3 = -4x + 8 {subtact 3 from both sides}
y = -4x + 5 ← slope-intercept form

find QR. help please and thank you<3
Answer:
QR = 1.3
Step-by-step explanation:
Sides TQ and TS are congruent, thus Δ QST is isosceles.
RT is a perpendicular bisector, that is it bisects QS at right angles, thus
QR = RS = 1.3
The measure of length of QR is 1.3 units.
What is an isosceles triangle?Isosceles triangles are those triangles that have at least two sides of equal measure and two base angles are equal.
In the given triangle TQS, QT=TS=4.7 units, so triangle TQS, isosceles triangle.
In isosceles triangle TQS, TR is the perpendicular bisector.
Then QR=RS= 1.3 units
Therefore, the measure of length of QR is 1.3 units.

A -yard-long field is divided into parts of equal length. Mr. Gump paints a 6-yard-long strip in each part. How long is the unpainted strip in each part of the field
Answer:
9 yards
Step-by-step explanation:
THE QUESTION ABOVE ISN'T COMPLETE THEN I FIND THE SAME QUESTION WITH JUST CHANGE IN VALUES. CHECK IT BELOW;
A 208-yard-long road is divided into 16 parts of equal length. Mr. Ward paints a 4-yard-long strip in each part. How long is the unpainted strip of each part of the road?
EXPLANATION:
From the question, a 208-yard-long road is been parted into into 16 parts and they all have equal length.
Then we can determine the Length of each part as
(208-yard-long road/16 parts )
= 13
Then each part has a length of 13 yards
From the question, we know that 4-yard-long strip was painted in each part by Mr. Ward. Which means to determine the
unpainted strip of each part, we are going to use the expresion below.
(Length of each strip - length of painted strip)
= (13 yards - 4-yard-long strip )
= 9 yards
Therefore, the length of unpainted strip of each part of the road is 9 yards

4 cans of tomato sauce = 1 pan of lasagna
285 cans of tomato sauce = x pan of lasagna
4 = 1
285 = x
Cross product
4*x = 285*1
4x = 285
x = 285/4

Answer:
Question 7: Company A has a lower rate
Question 8: Caiden's vehicle gets more miles per gallon
Step-by-step explanation:
Question 7:
According to the table for Company B's rates, if you divide the total cost by the square footage in each row, you would get $2.75/ft² each time. Therefore, Company A would charge the Smiths a lower cost per square foot.
$2.25/ft² < $2.75/ft²
Company A < Company B
Question 8:
Using the given equation, we already know that Caiden's vehicle has a gas mileage of 16.2 miles/gallon The graph for Ethan's gas mileage can be figured out using slope. Taking the points (0, 0) and (2, 30) on the line, we can figure out the line's slope.
slope = rise/run,
where "rise" is how much you add or subtract to get from the first y-value to the second, and "run" is how much you add or subtract to get from the first x-value to the second.
slope = rise/run
slope = 30/2
slope = 15/1
The slope of the line is 15, so that means the line's equation is y = 15x. Therefore, Ethan's gas mileage is 15 miles/gallon.
16.2 mpg > 15 mpg
Caiden > Ethan

The volumes of two cylindrical cans of the same shape vary directly as the cubes of their radii. If a can with a six-inch radius holds 1½ pints, how many gallons will a similar can with a 24-inch radius hold?
Answer:
The second similar can with a radius of 24-inch radius will hold 12 gallons
Step-by-step explanation:
The given parameters are;
The volumes of the cylindrical can ∝ (The radius of the cans)³
The volume of first can, V₁ = 1¹/₂ pints
The radius of the first can, r₁ = 6-inch
The radius of the second can, r₂ = 24-inch
Therefore, we have;
V ∝ r³
V = k × r³
∴ 1¹/₂ pints ∝ (6 in.)³
1¹/₂ pints = 43.3125 in³
∴ 43.3125 in³ = k × 216 in.³
The constant of proportionality, k = 43.3125/216 = 0.2005208333
Therefore, we have for the second can, we have;
V₂ = k × r₂³ = 43.3125/216 × (24 in.)³ = 2772 in.³
The volume of the second can = 2772 in.³
1 in.³ = 0.004329 gallons
∴ 2772 in.³ = 2772 × 0.004329 gallons = 12 gallons
Therefore, the volume the second similar can with a 24-inch radius will hold = 12 gallons.
At a swimming pool the ratio of those wearing sunscreen to those not wearing sunscreen was 7 to 5. If the number of people not wearing sunscreen was 30, then how many people were wearing sunscreen?
Answer:
42 people are wearing sunscreen
Step-by-step explanation:
Step one:
given data
We are given that the ratio of those wearing sunscreen to those not wearing sunscreen was 7 to 5.
i.e 7:5
number of people not wearing sunscreen is 30
let us use part to part method to solve this problem
let the number of people wearing sunscreen be x
so,
7/5= x/30
cross multiply we have
5x=210
divide both sides by 5
x= 210/5
x=42 people are wearing sunscreen
Answer:
I think the answer is 42 to 30. 42 kids wearing sunscreen and 30 kids were not. 30 divided by 5 is 6. 6 x 5 is 30. so 6 x 7 is 42. Hence 42 to 30. :)

How do you write 58.84% as a decimal?
Answer:When you ask, "What is 58.84 as a decimal?", we assume you want to know what 58.84 percent is as a decimal. In other words, 58.84 percent converted to decimal.
First, we will tell you why it is useful to know 58.84 as a decimal.
Normally, to calculate 58.84 percent, you would multiply a number by 58.84 percent and then you would take the product of that and divide it by 100 to get the answer.
Instead, you can simply multiply a number by 58.84 as a decimal to get the answer.
58.84 ÷ 100 = 0.5884
