Answer:
a) He can find the answer in one way
b) We make use of Addition property of mathematics
c) Total number of blocks = 12 blocks
Step-by-step explanation:
a) He can find the answer in one way
b) We make used of addition property of mathematics
c) The total number of blocks he is having is calculated as:
Blue blocks + Pink blocks + Green blocks
Where
Blue blocks = 5
Pink blocks = 3
Green blocks = 4
Hence:
Total number of blocks = 5 + 3 + 4 = 12 block

Find the value of x. Using trig
Hi there! We can find the value of x by using this equation.
[tex] \large \boxed{tanx = \frac{19}{23} }[/tex]
If you remember, tanx = opposite/adjacent. We focus on the angle x currently.
Now that you might wanna ask if there is a value of x that makes 19/23. The answer is yes but in decimal.
[tex] \large{arctan( \frac{19}{23} )} = x[/tex]
You might wanna put arctan(19/23) in a calculator since it's not really possible to get the square root like value by yourself.
arctan(19/23) is 0.69
Then we round up and get 0.7
Hence, the value of x ≈ 0.7
Answer
x ≈ 0.7 (rounded)Questions can be asked through comment.
Hope it helps, and Happy Learning! :)
Sarah walks uphill at an average of 2 miles per hour, and downhill at an average of 4 miles per hour. She goes for a 6 mile hike up a hill, and then returns downhill by the same route. What is Sarah's average speed for the whole journey?
Answer:
48
Step-by-step explanation:
Answer:
Average of 3mph
Step-by-step explanation:
If Sarah goes uphill at 2mph and downhill at 4mph.
Then to find the average you can:
Add 2 plus 4
which equals 6
Then divide the sum of 6 by the number of values given, there are two values (2 and 4)
6 divided by 2 equals 3
So the average is 3mph

A 32 oz water bottle costs $10.70.
___ oz per water bottle
___ dollars per ounce
round answer to nearest hundredth
Answer:
32 oz per water bottle
$0.33 dollars per ounce
Step-by-step explanation:
We are already given 32 oz as the amount per water bottle, so all we need to do is calculate the dollars per ounce. We can do this by dividing the cost of the water bottle by the number of ounces.
$10.70 ÷ 32= 0.334375 ------> 0.33
Rounding to the hundredths place we get $0.33.

x= how many members are in the group
x= 100/x
x= 100/(x-5)
x(x-5)=100
x^2-5x=100
x^2-5x-100=0
and then use the quadratic formula (i can't type it srry)
Answer:
25 membersStep-by-step explanation:
Initial number of members: x
Sum of money: K£ 100
Each had to pay: 100/x
Five members less, each paid K£1 more, we get equation:
100/x + 1 = 100/(x - 5)Multiply all terms by x(x - 5) and solve the quadratic equation:
100(x - 5) + x(x - 5) = 100x100x - 500 + x² - 5x - 100x = 0x² - 5x - 500 = 0x = (5 + √(5² + 4*500))/2 x = (5 + √2025)/2x = (5 + 45)/2x = 25The second root is ignored as negative.
On Tuesday afternoon at camp, Connor did archery and sailing before dinner. Archery started at 12:00 P.M. Connor spent 1 hour and 15 minutes at archery and 2 hours sailing. What time did sailing end?
Answer:
Sailing end at 3:15 AM
Step-by-step explanation:
Connor did archery and sailing before dinner (in that order).
He started at 12:00 PM
We know that:
In archery, Connor spent 1 hour and 15 minutes
In sailing, Connor spent 2 hours.
The total time spent is:
1 hour + 15 minutes + 2 hours
3 hours + 15 minutes.
Then sailing end 3 hours and 15 minutes after 12:00 pm = 0:00 am, this is:
3:15 AM
Sailing end at 3:15 AM
Solve for X. Show your work.
Answer:
x=8
Step-by-step explanation:
The angles are vertical angles so they are equal
8x+36 = 5x+60
Subtract 5x from each side
8x+36-5x = 5x+60-5x
3x+36 = 60
Subtract 36 from each side
3x+36-36 = 60-36
3x =24
Divide each side by 3
3x/3 = 24/3
x=8
Use 3.14 for π Round to the nearest 100th if necessary A ball has a diameter of 20 inches. What is its volume?
Answer:
4186.67 cubic inches
Step-by-step explanation:
Volume of a sphere = 4/3 π r³
π = 3.14
Diameter = 20 inches
Radius = r = Diameter/2 = 20 inches/2 = 10 inches
Volume of the sphere = 4/3 × 3.14 × (10 inches)³
Volume of the sphere = 12560 ÷ 3
= 4186.6666667 cubic inches
Approximately to the nearest hundredth = 4186.67 cubic inches
Therefore, the volume of the ball is 4186.67 cubic inches.
a rectangular plot has a perimeter of 124cm. The width is 2cm shoter than the lengh.What is the area of the rectangle?
Answer:
[tex]area = 960cm^2[/tex]
Step-by-step explanation:
Perimeter = 2 x (length + width) ------(1)
Perimeter = 124cm
Let length be x
Given width is 2cm shorter than length , that width = x -2
[tex]Perimeter = 2 (x + (x -2))\\\\124 = 2(x +x -2)\\\\62 = 2x -2 \\64 = 2x\\x = 32[/tex]
Length = 32cm
Width = 32 - 2 = 30cm
Area = length x width
[tex]= 32 \times 30 = 960cm^2[/tex]

A large western stare consists of 3872 million acres of land. Approximately 82% of this land is federally owned. Find the number of acres that are not federally owned.
Answer:
696.96 million acres of land
Step-by-step explanation:
Acres not federally owned = Percentage of acres not federally owned x total acres of land
Percentage of acres not federally owned = 100% - percentage of acres federally owned
100% - 82% = 18%
0.18 x 3872 = 696.96 million acres of land
Sara claims that a sequence of transformations carries Rectangle 1 onto Rectangle 2. Which of the following sequences of transformations can be used
to support Sara's claim?
A
a reflection over the y-axis, followed by a reflection over the x-axis.
B
a translation of 7 units to the left, followed by a translation of 8 units up.
С
a reflection over the x-axis, followed by translation of 4 units to the right
D
a rotation of 270° clockwise about the origin, followed by a reflection over the y-axis.
The sequences of transformations can be used to support Sara's claim that is A; a reflection over the y-axis, followed by a reflection over the x-axis.
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs), etc.
Given that Sara claims that a sequence of transformations carries Rectangle 1 onto Rectangle 2.
When a graph is reflected along an axis, it says x-axis, then that leads the graph to go just to the opposite side of the axis as if we can see it in a mirror.
If we study it more, then we will find that it is symmetric, however, each point is equidistant from the axis of reflection as that of the image of that point.
Therefore, The sequences of transformations can be used to support Sara's claim that is A; a reflection over the y-axis, followed by a reflection over the x-axis.

A line is perpendicular to y = 3/7x - 2 and intersects the point (3, 3). What is the equation of this perpendicular line?
Answer:
y = -7/3x + 10
Step-by-step explanation:
Step 1: Find the slope of the perpendicular line
Do this by taking the negative inverse of the first line
m = -7/3
Step 2: Find b
y = mx + b
y = -7/3x + b
3 = -7/3(3) + b
3 = -7 + b
b = 10
