Answer:
She must work at least 7 hours. All possible values are 7, 8, 9, 10
Step-by-step explanation:
14 - 4 = 10
4($7)=$28
$130-$28=$102
$102÷$15=6.8
$15x7=$105
$105+$28=$133
$15x8=$120
$120+$28=$148
$15x9=$135
$135+$28=$163
$15x10=$150
$150+$28=$178
Answer:
I'm going to also give you how to get the answer... not just the answer.. you will need to know this for a test :/ so learn it :P
Step-by-step explanation:
Sin(30)=12
to remember what Sin and Cos at those speacial angles in degrees are.. just use this Sin(degrees)
Sin(0) = 0/2 =0
Sin(30)= /2 = 1/2
Sing(45) = /2 = /2
Sin(60)=/2 = /2
Sin(90)=/2 = 1
Cos is exactly the same but counts backwards from 90°
Cos(90) = 0/2 =0
Cos(60) = /2 = 1/2
Cos(45) = /2 = /2
Cos(30) = /2 = /2
Cos(0) =/2 = 1
note that the numerators just count from 0,1,2,3,4 , see? you can remember sin and cos now :) since you can count to 4 :P
Sin(30) =12
1/2 =12 while that statement makes no sense.... obviously 1/2 isn't equal to 12 but.. what's being said is that the angle of 30° gives you a side that is 12 units long.
so looking at what I wrote above.. which angle in degrees matches Sin when you look at Cos?
Sin(30)= 1/2 and Cos(60) also = 1/2 huh
sooo β = 60 °
got it? :/
Answer:
<h2>The value of D is 6 and the value of F is -26.</h2>
Step-by-step explanation:
Givens
- The center of the circle is at (1, -3), and its radius is 6 units.
The best way to find the general form of the circle, it's to use the center-radius form
In this case, , and . Replacing all these values in the formula, we have
Now, we solve each power
Where:
However, Ben wrote the expression with F as the constant. So,
Therefore, the value of D is 6 and the value of F is -26.

Answer:
48 ft
Step-by-step explanation:
Here, we want to find the length of the wire
from the diagram, we can identify two similar triangles
The smaller one and a bigger one
Mathematically, when two triangles are similar, the ratio of their corresponding sides are equal
We can start by getting the height of the tower
we have this as:
8/11 = 28/x
8 * x = 28 * 11
8x = 308
x = 308/8
x = 38.5 ft
So as we can see, the wire represents the hypotenuse of the larger triangle that measures 28 ft base and 38.5 ft height
So we can use the Pythagoras’ theorem to get the hypotenuse
Let us call this g
mathematically according to the theorem, the square of the hypotenuse equals the sum of the squares of the two other sides
thus, we have it that;
g^2 = 38.5^2 + 28^2
g^2 = 2,266.25
g = √2,266.25
g = 47.61 which is approximately 48 ft
