Answer:
C. Brooke finished in 115 minutes, so she was faster.
Step-by-step explanation:
Lets convert the measurements into the same units.
125 minutes (already in minutes)
1 hour (60 minutes) 55 minutes
60+55=115
Brooke ran the half marathon in 115 minutes
Since 115 is less than 125, Brooke was faster

Trigonometric functions
9514 1404 393
Answer:
β ≈ 39.9°
θ ≈ 50.1°
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relationships between the sides of a right triangle and the trig functions of the acute angles.
For angle β, we know the opposite side and the hypotenuse, so the relevant relation is ...
Sin = Opposite/Hypotenuse
sin(β) = 61/95
The inverse function is used to find the angle when the sine is known.
β = arcsin(61/95) ≈ 39.9°
Of course, the angle θ is the complement of this:
θ = 90° -39.9° = 50.1°
Answer:
Step-by-step explanation:
sin β = 61/95 = 0.642105
β = 39.95 degrees.
O = 90 - 39.95
= 50.05 degrees
cos O = 61/95.
Note that cos (90-β) = sin β.

please I don't really get the question I need more of an explanation of it.
thanks
Step-by-step explanation:
it means to arrange the number from smallest to the biggest
13/21, 2/3 , 6/7
since 13/21 =0.61904....

A stadium has 47,000 seats. Seats sell for $42 in Section A, $36 in Section B, and $30 in Section C. The number of seats in Section A equals the total number of seats in Sections B and C. Suppose the stadium takes in $1,779,000 from each sold-out event. How many seats does each section hold?
Answer:
section A holds 23,500 Section B holds 11,750 And Section C holds 11,750
Step-by-step explanation:
Section A is half of the stadium so divide 47,00 by 2 you get 23,300 so that is Section A than b and c are the other half for divide 23,500 by 2 and you get 11,750

how do you find the derivative
Answer:
h'(x) = -10x + 20
Step-by-step explanation:
To get the derivative of [tex]ax^{n}[/tex], simply use the following formula:
[tex]a(n)x^{n-1}[/tex]
We have the function, h(x) = -5x^2 + 20x
Using the formula, we get the derivative to be:
-10x + 20
so h'(x) = -10x + 20

What value is equivalent to 5 − 4(1 + 2^3)?
A) -511
B) -103
C) -31
D) 9
Answer:
C(-31)
Step-by-step explanation:
= 5 - 4(1 + 2^3)
= 5 - 4(1 + (2 . 2 . 2))
= 5 - 4(1 + (4 . 2))
= 5 - 4(1 + 8)
= 5 - 4(9)
= 5 - 36
= (-31)
OPTION C
_________
[tex] \: [/tex]
5 - 4(1 + 2³) = ?
= 5 - (4(1) + 4(2³))
= 5 - (4 + 4(8))
= 5 - (4 + 32)
= 5 - 36
= -31

D:2 days
pllzzzz I NEED BRAINLIEST!!
Answer:
C:1 and 3/4
Step-by-step explanation:
We can use a ratio to solve
1 day x days
------- = -------------
24 hours 42 hours
Using cross products
1 * 42 = 24x
Divide each side by 24
42/24 = x
21/12 = x
7/4 = x
4/4 + 3/4 =x
1 3/4 =x
1 3/4 days = x

What are the coordinates of the intersection of the graphs of 3x - y^2 = 12 and y = -3
Answer:
(7,-3)
Step-by-step explanation:
y = -3
substitute in the first equation
3x - y^2 = 12
3x - (-3)^2 = 12
3x - 9 = 12
3x = 12 + 9
3x = 21
x = 7
coordinates of intersection (7,-3)
Find m Help me solve it please!!!!!!!!!!!!!
Answer:
56
Step-by-step explanation:
according to the sum of the exterior angles of a polygon, we get that the exterior angles of this polygon add up to 360
so our equation is: 9x-31+7x-2+4x+33=360,
the -31-2+33 cancel out,
and combining like terms gives us: 20x=360
so x=18,
from here we know that DCE equals to 180-7x+2, because it is an exterior angle, therefore the angle is 180-126+2, which is 56
can you find the equation for the math problem?

Kaylin mixed two liquids for a science experiment. One container held 7/8 cup and the other held 9/10 cup.what is the total amount of the mixture
Answer:
71/40
Step-by-step explanation:
We find the common denominator, which is 40,
so the first numerator is 9x4, and the second numerator is 7x5,
and adding them we get 71
and so the answer is numerator/denomitar = 71/40
Answer:
1 31/40 cupStep-by-step explanation:
Add up the volumes to find the volume of the mixture:
7/8 + 9/10 = 5*7/5*8 + 4*9/4*10 =35/40 + 36/40 =71/40 =1 31/40 cup
