Bria asked her classmates whether they prefer math or science. Nine of her classmates said math and eight of her
classmates said science. Which inequality correctly compares the fraction who prefer science to the fraction who
prefer math?
Answer:
8/17<9/17
Step-by-step explanation:
Might be wrong with my answer but my logic was that if there are 9 students who prefer math and 8 who prefer science, that there are 17 students total. If there are 17 students total the denominator should be 17. Since 8 of them prefer science, we can write that as 8/17 because 8 out of the 17 students prefer science. Similarly we can write the number of students who prefer math as 9/17 because there are 9 students out of 17 who do.

In the triangle above, the console of p degrees is 0.8 what is the sine of q degrees
Answer:
Step-by-step explanation:
[tex]cosp=(8/10)\\ \\ p=cos^{-1}(8/10)\\ \\ q=90-p\\ \\ q=90-cos^{-1}(8/10)\\ \\ sinq=sin(90-cos^{-1}(8/10)\\ \\ sinq=(8/10)[/tex]
In the triangle above, the console of p degrees is 0.8. So, the sine of angle q is 0.6.
It seems like there is a description of a triangle with angles p and q, where the console of angle p is 0.8. However, the term "console" is not familiar in the context of trigonometry. I assume you meant "cosine" instead of "console."
If that's the case, let's proceed with the assumption that cos(p) = 0.8.
The cosine of an angle is the ratio of the adjacent side to the hypotenuse in a right-angled triangle. To find the sine of angle q, we need to use the Pythagorean trigonometric identity:
sin²(q) + cos²(q) = 1
We already know that cos(p) = 0.8, and since the sum of angles in a triangle is 180 degrees, we can find q:
q = 180 - p
Now, let's calculate sin(q):
sin²(q) + cos²(q) = 1
sin²(q) + (0.8)² = 1
sin²(q) = 1 - 0.64
sin²(q) = 0.36
Now, take the square root of both sides to find sin(q):
sin(q) = √0.36
sin(q) = 0.6
So, the sine of angle q is 0.6.

The length of a rectangle is three inches more than four times the width. The perimeter of the rectangle is 56 inches. What is the width of the rectangle?
Answer:
The width of the rectangle is 5 inches.
Step-by-step explanation:
Perimeter of a rectangle: 2L+2W where L=length and W=width
P=56
56=2(4W+3)+2W
56=8W+6+2W
56=8W+2W+6
56=10W+6
56-6=10W
50=10W
W=50/10=5
W=5
L=4W+3=4(5)+3=20+3=23

Find three consecutive even integers such that the product of the first and the second is 8
greater than - 10 times the third integer.
Answer:
-4, -2, 0 or -8, -6, -4
Step-by-step explanation:
#1 =x
#2 = x+2
#3 = x+4
x(x+2) = -10(x+4) + 8
x^2 + 2x = -10x - 40 + 8
x^2 + 12x + 32 = 0
(x+8)(x+4) = 0
x = -8 or x = -4 so:
#1 = -8 or -4
#2 = -6 or -2
#3 = -4 or 0

Triangle TVW is dilated according to the rule
DO,(x,y)(three-fourths x, three-fourths y) to create the image triangle T'V'W', which is not shown.

What are the coordinates of the endpoints of the segment T'V'?
T'(-3, 6) and V'(0, 3)

What is dilation of triangle?Dilation of triangle means each point is stretched outwards or inwards from the center point by multiplying by the scale factor to form a similar triangle.
We have,
Triangle [tex]T V W[/tex] which has points [tex](- 4, 8)[/tex], [tex](0, 4)[/tex], and [tex](4, 4)[/tex] on a coordinate plane.
Scale factor [tex]\frac{3}{4} x, \ \frac{3}{4} y[/tex]
It has to be dilated to create a new triangle [tex]T'V'W'[/tex] .
So,
To create a new triangle [tex]T'V'W'[/tex] we have to multiply the original triangle's coordinate by scale factor, to get new triangle's coordinate .
So, we have to dilate the coordinates by [tex]\frac{3}{4} x, \ \frac{3}{4} y[/tex] ,
[tex]T'=(- 4, 8)=\frac{3}{4} *(-)4, \frac{3}{4} *8= (-3,6)[/tex]
[tex]V'=(0, 4)=\frac{3}{4} *0, \frac{3}{4} *4=(0,1)[/tex]
[tex]W'=(4, 4)=\frac{3}{4} *4,\frac{3}{4} *4=(0,0)[/tex]
So, the coordinates of triangle [tex]T'V'W'[/tex] after dilation are [tex](-3,6), \ (0,1), \ (0,0)[/tex] . Hence we can say that the coordinates of the endpoints of the segment [tex]T'V'[/tex] are [tex](-3,6), \ (0,1).[/tex]

Which runs faster: a cheetah that can run 60 feet in 6 seconds or a gazelle that can run 100 feet in 10 seconds?
They run at the same speed.
A gazelle runs faster.
A cheetah runs faster.
Answer:
They run at the same speed
Step-by-step explanation:
First, you have to find a way seeing how fast both animals run in the same amount of time. You can find out how fast they both run in one second.
60 feet in 6 seconds is how many feet in one second? Well, you can do 60/6 (60 divided by 6) and you will see that in one second, the cheetah can run 10 feet
100 feet in 10 seconds is how many feet in one second? Same thing, you can do 100/10 (100 divided by 10) and you will see that the gazelle can run 10 feet in one second.
Finally, you compare the two answers from the two animals. For the cheetah, we learned that it can run 10 feet in one second, and for the gazelle, we learned that it can run 10 feet in one second. So, we know that they run at the same speed.
Thank you! Please let me know if this was helpful!
Answer:
Cheeta's speed = 10 feet per second
Gazelle's speed = 10 feet per second
Hence, They run at the same speed.
Step-by-step explanation:
Determining the Cheeta's speed:
Covered distance = 60 feet
Time taken = 6 seconds
Speed = Covered distance / Time taken
= 60 / 6
= 10 feet per second
Therefore, Cheeta's speed is 10 feet per second.
Determining the Gazelle's speed:
Covered distance = 100 feet
Time taken = 10 seconds
Speed = Covered distance / Time taken
= 100 / 10
= 10 feet per second
Therefore, Gazelle's speed is 10 feet per second.
Conclusion:
Cheeta's speed = 10 feet per second
Gazelle's speed = 10 feet per second
Hence, They run at the same speed.

Answer:
n = 52
Step-by-step explanation:
the given triangle is an isoceles triangle as one angle is of 90 degrees, the other two of 45 degrees each.
the sides congruent to congruent angles I. e (45 degrees) are also congruent.
therefore one side is given I. e 52
so the other side being congruent will also be congruent.
therefore n = 52 units
