Sammie read at the rate of 25 pages per hour. Alex read at the rate of 1/2 of a pages per minute. Who was reading faster? By how many pages per hour faster?
Answer:
Alex and 5 pages
Step-by-step explanation:
Sammie 25 pages per hour
Alex 1/2 pages per minute
You do 1/2x60=30 because you can find out how many pages he can read per hour. Which is 30 pages per hour. So Alex can read 30 pages per hour and Sammie can only read 25 pages per hour. To find how many pages he reads faster per hour, you have to take 30 and subtract it by 25 to get 5 extra pages. So Alex reads 5 pages faster per hour. In the end, Alex reads faster than Sammie by 5 more pages per hour.
Hope this helps! Please give brainliest.
Answer:
Alexa and 5 pages.

I need help I’m stuck on this question.
Answer:
No
Step-by-step explanation:
Given b =4, h=6, H=3, let us find the area.
First we find the area of the triangular face.
(b*h)/2 = 4*6/2 = 24/2 = 12
Then we multiply 12 by the height of the cheese
12*H = 12*3= 36
36 <40, therefore she does not have enough.

What are the angle measures of triangle VUW?
m∠V = 30°, m∠U = 60°, m∠W = 90°
m∠V = 90°, m∠U = 60°, m∠W = 30°
m∠V = 30°, m∠U = 90°, m∠W = 60°
m∠V = 60°, m∠U = 90°, m∠W = 30°
Answer:
m∠V = 60°, m∠U = 90°, m∠W = 30°
Step-by-step explanation:
hope this helps y'all out
The angle measures of triangle VUW are m∠V = 90°, m∠U = 60°, m∠W = 30°
Application of SOH CAH TOA identityFrom the given diagram;
Opposite side to <V = 3√3 cmHypotenuse = 6cmAccording to the rule:
sin <V = opp/hyp
sin <V = 3√3/6
sin <V = √3/2
<V = 60 degrees
Since the triangle is right-angled, the measure of m<U is 90 degrees
Also, the sum of interior angle of a triangle is 180 degrees, hence;
60 + 90 + <W = 180
<W = 180 - 150
<W = 30 degrees
Hence the angle measures of triangle VUW are m∠V = 90°, m∠U = 60°, m∠W = 30°

For what value of do the expressions 2+3 and 3−6 have the same value?
[tex]x[/tex] =
Answer:
x = 9
Step-by-step explanation:
The expressions are 2+3 and 3−6.
We need to find the value of x such that the expressions 2+3 and 3−6 have same value.
2+3 = 3−6
Taking like terms together,
3+6 = 3x-2x
⇒ x = 9
So, the value of x is 9 such that 2+3 and 3−6 have same value.

A shelf is supported with brackets as pictured in the diagram below. What is the
width of the shelf?
A 14 in.
B 16 in.
C 12 in.
D 10 in.
The width of the shelf is 10 inches. The correct option is D.
Describe Right Angled Triangle?A right-angled triangle is a triangle that has one angle measuring 90 degrees, which is known as the right angle. The sides adjacent to the right angle are known as the legs of the triangle, while the side opposite the right angle is known as the hypotenuse.
The Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs, is one of the fundamental theorems of mathematics and is used extensively in various fields.
Let's call the width of the shelf "x". According to the given diagram, we have a right triangle where the base is x, the perpendicular is 10 inches, and the angle between the hypotenuse and the perpendicular is 45 degrees.
Using trigonometric ratios, we know that:
tan(45) = perpendicular/hypotenuse
tan(45) = 10/x
Since tan(45) is equal to 1, we can simplify the equation to:
1 = 10/x
Solving for x, we get:
x = 10
Therefore, the width of the shelf is 10 inches.

4 4/7 + ⅖
????????????
Answer:
Step-by-step explanation:
First you would make 4 4/7 into an improper fraction which you would do by:
7 times 4 is 28 plus 4 is 32.
So the improper fraction is 32/7.
Next you make the denominators the same by finding the least common multiple which is 35.
35 divided by 7 is 5, which also means that 35 divided by 5 is 7.
Then you have to multiply the numerator by the same thing that you multiplied the denominator by.
32 times 5 is 160.
2 times 7 is 14.
So the new problem is 160/35 + 14/35.
You add 160 + 14 which is 174.
So the final answer is 174/ 35 because it can not be simplified any further unless you make it a mixed number which would be: 4 34/35
Which coordinates does not represent a function?
Answer:
the first one
Step-by-step explanation:
Answer:
Set 1
Step-by-step explanation:
To have a function, you cannot have the same x-coordinate more than once.
In sets 2, 3, and 4, all x-coordinates of each set are different, so they are functions.
In set 1, the x-coordinate 1 appears twice, so set 1 is not a function.
