At angle θ lies in Quadrant III. If cosθ=-0.487, what is tanθ rounded to the nearest thousandth??
Answer:
TanФ=-1.793
Step-by-step explanation:
[tex]Sin^{2} (A) + Cos^{2} (A) = 1[/tex]
[tex]Sin(A)=\sqrt{1-Cos^{2} (A)}[/tex]
[tex]Tan(A) = \frac{Sin(A)}{Cos(A)}[/tex]
[tex]Tan(A) =\frac{\sqrt{1-Cos^{2}(A) } }{Cos(A)} \\Tan(A) =\frac{\sqrt{1-(-.487)^{2} } }{-.487}=-1.793433202[/tex]

Ted has an impressive total of 145 dimes and quarters. The collection is worth $24.25.
How many dimes and quarters does he have?
9514 1404 393
Answer:
80 dimes65 quartersStep-by-step explanation:
Let q represent the number of quarters (the higher-value item). Then 145-q is the number of dimes. The total collection is worth ...
0.25q + 0.10(145 -q) = 24.25
0.15q = 9.75 . . . . . . . . . . . . . . . . subtract 14.50; collect terms
q = 65 . . . . . . . . . . . divide by 0.15
d = 145 -q = 80
Ted has 80 dimes and 65 quarters.
___
Check
80 dimes: $8.00
65 quarters: $16.25
Total: $8.00 +16.25 = $24.25.

Quadrilateral ABCD with AB= 5.5cm,BC= 3.5cm,CD= 4cm,AD= 5cm and <A= 45°.
Answer:
⇒ Draw a line segment AB=5.5cm
⇒ Take A as a center and draw an angle of 45
o
.
⇒ Cut off AD=5cm
⇒ Take D as a center with radius 4.5cm and draw an arc.
⇒ Take B as a center with radius 3.5cm and draw an arc, which meets previous arc at point C.
⇒ Join BC and CD.
∴ ABCD is a required quadrilateral.

find the median for each set of data 4,12,7,6,10,5,11,8
Answer:
7.5
Step-by-step explanation:
The median is the middle data in a set. To find the median first order the set for least to greatest. In this case, 4,5,6,7,8,10,11,12. Then find the number in the middle, however, because there is an odd number of data you must take the mean of the two middle numbers. The two numbers in the middle are 7 and 8, so to find the mean of these numbers add them then divide by the number of terms, aka 2. (7+8)/2=7.5, therefore the median must be 7.5.

Find the measure of the numbered angle.
m∠7 =
Answer:
∠7 = 90°Step-by-step explanation:
∠7 = 180 - 90
∠7 = 90°
see image below
Answer:
90°
Step-by-step explanation:
angle 7 is supplementary to the angle next to itself which has a measurement of 90° and since the sum of two supplementary angle would be 180° we can say that m<7 = 90° as well

A tropical punch recipe calls for 300 ml of sugar for every 222 flavor packages. Write an equation that shows the relationship between s, the amount of sugar in milliliters, and f, the number of flavor packages for this recipe.
Answer:
s = 150f
Step-by-step explanation:
A tropical punch recipe calls for 300 ml of sugar for every 2 flavor packages. Write an equation that shows the relationship between s, the amount of sugar in milliliters, and f, the number of flavor packages for this recipe.
The amount of sugar in milliliters = s
The amount of flavor packages for these recipe = f
The relationship between 2 variables
= y ∝ x
y = kx
k = constant of proportionality
Hence:
s ∝ f
s = kf
Note ,
s = 300
f = 2
300 = 2k
k = 300/2
k = 150
Therefore, the equation that shows the relationship between s, the amount of sugar in milliliters, and f, the number of flavor packages for this recipe is:
s = kf
s = 150f
Answer:
2=150f

In the equation y=2X+7 which
number is the slope?
Slope (m)
Answer:
2 is the slope
Step-by-step explanation:
the equation is y=mx+b so if it is
y= 2x+7 that means the slope is 2
Answer:
2
Step-by-step explanation:
This equation is in y=mx+b form.
Slope = m
Y-intercept = b
This will give you the slope of 2 :)

Find the values of a and b please I will mark brainliest. (make sure to show your work)
Answer:
a = 29
b = 20
Step-by-step explanation:
2a - 1 = 57
+ 1 + 1
2a = 58
/ 2 / 2
a = 29
2a - 1 + 7b - 17 = 180
2 (29) - 1 + 7b - 17 = 180
58 - 1 + 7b - 17 = 180
57 + 7b - 17 = 180
7b + 40 = 180
- 40 - 40
7b = 140
/ 7 / 7
b = 20
