Theoretically, if a month is chosen 300 times,
how many times would you expect a month
that starts with the letter J?
Answer:
75 times.
Step-by-step explanation:
Well there are 12 months and 3 of them start with the letter J, so theoretically, 25% of the months chosen will start with the letter J because [tex]\frac{3}{12}=\frac{1}{4}[/tex], which is 25%. 25% of 300 (or [tex]\frac{300}{4}[/tex], for those who like fractions) is 75, so theoretically, we can expect a month that starts with the letter J 75 times.

Hello I was wondering if someone would help me with this tricky question?
Answer:
The two coordinates should be (6, 3) and (10, 4).
Step-by-step explanation:
rise / run
y-value of the 2nd coordinate = 3 + 1 = 4
x-value of the 2nd coordinate = 6 + 4 = 10
The two coordinates should be (6, 3) and (10, 4).

The triangle on the grid will be translated two units left.
On a coordinate plane, triangle A B C has points (negative 1, negative 1), (negative 1, negative 5), (0.5, negative 5).
Which shows the triangle when it is translated two units left?
On a coordinate plane, triangle A prime B prime C prime has points (1, negative 1), (1, negative 5), (2.5, negative 5).
On a coordinate plane, triangle A prime B prime C prime has points (negative 3, negative 1), (negative 3, negative 5), (negative 1.5, negative 5).
On a coordinate plane, triangle A prime B prime C prime has points (negative 1, 1), (negative 1, negative 3), (0.5, negative 3).
On a coordinate plane, triangle A prime B prime C prime has points (negative 1, negative 3), (negative 1, negative 7), (0.5, negative 7)
Given:
The vertices of a triangle are A(-1,-1), B(-1,-5), C(0.5,-5).
The figure is translated 2 units left.
To find:
The vertices and the diagram of the triangle after the given translation.
Solution:
if a figure is translated 2 units left, then
[tex](x,y)\to (x-2,y)[/tex]
Using the above rule, we get
[tex]A(-1,-1)\to A'(-1-2,-1)[/tex]
[tex]A(-1,-1)\to A'(-3,-1)[/tex]
Similarly,
[tex]B(-1,-5)\to B'(-1-2,-5)[/tex]
[tex]B(-1,-5)\to B'(-3,-5)[/tex]
And,
[tex]C(0.5, -5)\to C'(0.5-2,-5)[/tex]
[tex]C(0.5, -5)\to C'(-1.5,-5)[/tex]
So, the vertices of the triangle after the translation are A'(-3,-1), B'(-3,-5), C'(-1.5,-5).
Therefore, the correct option is B.

How many toys would Louis build in 10 hours if she built 3 toys every 20 minutes?
Answer:
90 toys
Step-by-step explanation:
We should use the same unit for time. Rewrite 20 minutes as 1/3 hour.
The unit rate is then:
3 toys 9 toys
----------------- = -----------
1/3 hour hour
Multiply this unit rate by 10 hours, obtaining 90 toys
Find the coordinates of the endpoint of the image?
Given:
The end points of the line segment AB are A(-2,-3) and B(4,-1).
The rule of translation is:
[tex](x,y)\to (x+4,y-3)[/tex]
To find:
The coordinates of the end points of the line segment A'B'.
Solution:
It is given that the end points of the line segment AB are A(-2,-3) and B(4,-1).
We have,
[tex](x,y)\to (x+4,y-3)[/tex]
By using the above translation rule, we get
[tex]A(-2,-3)\to A'(-2+4,-3-3)[/tex]
[tex]A(-2,-3)\to A'(2,-6)[/tex]
And
[tex]B(4,-1)\to B'(4+4,-1-3)[/tex]
[tex]B(4,-1)\to B'(8,-4)[/tex]
Hence, the endpoint of the line segment A'B' are A'(2,-6) and B'(8,-4).
WILL GIVE BRAINLIEST!!! If w = 6 units, x = 3 units, and y = 5 units, what is the surface area of the figure?
The surface area of the figure is 204 sq.unit.
What is Surface Area ?The surface area of a three dimensional figure is the sum of area of all its faces.
Here a three dimensional figure is given and surface area has to be calculated.
The base is a cuboid
Surface Area of a cuboid = SA= 2lw+2lh+2hw
SA = 2 * 6 * 6 +2 * 6 * 3 + 2 * 6 * 3
SA = 144 sq.units
The Surface Area of the 4 triangle surface = 4 * (1/2) * base * height
SA = 2 * 6 * 5 = 60 sq.units
The total surface area = 144 +60 = 204 sq.units
Therefore the surface area of the figure is 204 sq.unit.

Answer:
the answer is D
hope it help
Answer: D, x²-6x+9
Step-by-step explanation:
(x-3)² is the same as (x-3)(x-3).
So you would do:
x times x=x²
x times -3=-3x
-3 times x=-3x
-3 times -3=9
The equation would look like this:
x²-3x-3x+9
Then you would have to collect the like terms. Like terms are terms that have the same variables and powers. So it would look like this:
x²-6x+9

A cup of milk has 10 grams of protein. How much protein is in 2.5 cups of milk?
Answer:
25 grams of protein
Step-by-step explanation:
10 grams of protein is in 1 cup of milk.
To understand how many grams of protein are in 0.5 cups of milk, I would need to divide 10 by 2, to get 5.
There are 5 grams of protein in 0.5 cups of milk.
Now if I want to see how many grams of protein are in 2 cups of milk, I would multiply 10 by 2, to get 20.
There are 20 grams of protein in 2 cups of milk.
But, the question is asking for how much protein is in 2.5 cups of milk.
Since we know how much is in 2 cups, and 0.5, we can just add them together, because 2+0.5 is 2.5.
20+5 is 25 grams.
There are 25 grams of protein in 2.5 cups of milk.
Which is greater 52,800 cm or 1 km?
Answer:
1 km

5

It has one right angle and two acute angles.
Answer:

Step-by-step explanation:
Complete question
Martin drew a triangle. Its sides were 3\text{ cm}3 cm3, start text, space, c, m, end text, 4\text{ cm}4 cm4, start text, space, c, m, end text, and 5\text{ cm}5 cm5, start text, space, c, m, end text. It has one right angle and two acute angles. Complete the sentence to describe the triangle Martin drew. Martin's triangle is ----- and ------ .
First you must know that for a triangle to be right angled, the square of the largest side must be equal to the sum of the square of the other two sides
Given
Largest side c = 5
Other sides a = 3 and b=4
Square of largest side c² =5²=25
Sun of the squares of other two sides = a²+b²
Sum of the squares of other two sides =3²+4²
Sum of the squares of other two sides = 9+16 =25
Since c² =a²+b² according to pythagoras theorem, hence the triangle is right angled
If y varies inversely as x, and y = 33 when x = 7, what is the constant and what is value of y when x=11?
Answer:
We have that y = 21 when x = 11.
Step-by-step explanation:
We solve this question by proportions, using a rule of three.
Since they vary inversely, we apply the inverse rule of three, that is, with lateral multiplication instead of diagonal.
33 - 7
y - 11
So
[tex]11y = 33*7[/tex]
Dividing both sides by 11
[tex]y = 3*7 = 21[/tex]
We have that y = 21 when x = 11.
y varies directly as x y=-8 when x=-2 what is the equation find x when y=32

29.95(0.85)
= 25.46
Find the price with the sales tax:
25.46(1.08)
= 27.5

What is algebraic Expression?Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.
We know that sin(x+37)°=cos(90°-(x+37)°) and cos(2x+8)°=sin(90°-(2x+8)°)
So we have sin(x+37)°=cos(2x+8)° becomes sin(x+37)°=sin(82°-2x)
For the above equation to be true, either of the following must hold:
x+37 = 82 - 2x (since the sin function is periodic)
x+37 = 180 - (82-2x)
Solving the first equation for x gives:
3x = 45
x = 15
Solving the second equation for x gives:
3x = 61
x = 20.33 (rounded to two decimal places)
Therefore, the possible values of x are 15 or 20.33 (rounded to two decimal places).
