Answer:
$41.04
Step-by-step explanation:
8% = 0.08
38(0.08) = 3.04
$3.04 is the tax for the jeans. Now we just have to add it to the price.
38 + 3.04 = $41.04
Answer:
$41.04
Step-by-step explanation:
0.08 (the tax converted from percentage) x 38 (initial cost) = 3.04(tax amount)
38(initial amount) + tax amount (3.04) = 41.04
the cost after tax is $41.04
understand now? To convert 8% to a decimal just move the decimal to the left twice (because we’re representing out of 100%)

A quadrilateral is inscribed in a circle. Find the measure of each missing angle as labeled below. Show your work and/or explain how you got your answer.
1 point for each correct angle measure and 1 point for explaining or showing how you got your answer. Don’t forget to label your answers.
Answer:
C = 95°
D = 72°
F = 108°
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary. Inscribed angles are half the measure of the arc they subtend. (The latter statement can be used to prove the former one.)
Using these relations, we have .
C = 180° -E = 180° -85° = 95°
D = 144°/2 = 72°
F = 180° -D = 180° -72° = 108°

A rectangular flower garden in Samantha’s backyard has 100 feet around its edge. The width of the garden is 20 feet. What is the length
Answer:
bces
Step-by-step explanation:
length:30ft
Step-by-step explanation:
if the perimeter is 100 than 20+20+x+x=100.
20+20=40
100-40=60
since there are two length sides, divide 60 by two and then you have your answer.
20+20+30+30=100

Step-by-step explanation:
Initial co-ordinate of p = ( 2, -2)
Rule for rotation 180° about the origin
(x,y) ----> ( -x , -y )
Meaning of the rule: To find the coordinates of a point that was rotated 180° about the origin all we have to do is add negative signs in front of the x and y values of the coordinates. THE NUMBER STAYS THE SAME. THE ONLY THING THAT CHANGES IS THE SIGN
* add - to the coordinates *
- ( 2 , -2 )
-1 * 2 = -2
-1 * -2 = 2
we end up with ( -2, 2 )
Hence the answer is B
For this one a rectangle was dilated and we have to find the scale factor and the new width.
We are given the pre image width (3) and length (4) and the new image length (12)
We can find the scale factor by dividing the new image length by the pre image length ( Note that you have to use corresponding sides. Like pre image height over new image height or pre image length over new image length. etc. )
So scale factor = 12 / 4 or 3
Now to find the new image width
We can do this by multiplying the pre image width (3) by the scale factor (3)
So new image width = 3 * 3
3 * 3 = 9
Hence the width of the enlarged print is C 9 inches
For this one we need to find x using angle rules
The angles shown are supplementary angles meaning that the sum of the two angles is 180
That being said we can create an equation to solve for x
180 = 64 + 4x + 16
Now we just solve using basic algebra
step 1 combine like terms
64 + 16 = 80
now we have 180 = 4x + 80
step 2 subtract 80 from each side
80 - 80 cancels out
180 - 80 = 100
now we have 100 = 4x
step 3 divide each side by 4
100/4 = 25
4x/4=x
we're left with x = 25
A basketball is thrown upward from a height of 6 feet at an initial speed of 15 feet per second. As the basketball travels, Earth's gravity slows it down.
The height of an object dropped from a height of 6 feet is given by h(t)=−16t2+6.
The distance in feet traveled by an object at a constant speed of 15 feet per second is given by d(t)=15t.
These two functions can be combined to build a new function, f, that models the height of the basketball as a function of time in t seconds.
Which choice shows how to combine h and d to build f
Answer: f(t)=h(t)+d(t)
f(t)=-16t^2+15t+6

PLEASE HELP !!!!!!!! What is the equation of the directrix for the following parabola: -8(x-5)=(y+1)^2
a. y=-3
b. x=7
c. y=7
d. x=-3
Answer:
x=7
Step-by-step explanation:
The directrix of the equation is x=7
What is directrix of parabola?The directrix of a parabola is a line that is perpendicular to the axis of the parabola. The directrix of the parabola helps in defining the parabola. A parabola represents the locus of a point which is equidistant from a fixed point called the focus and the fixed line called the directrix. The directrix and the focus are equidistant from the vertex of the parabola. Here we define the directrix for the standard equations of a parabola.
The directrix of the parabola y^2 = 4ax, having x-axis as its axis, passes through (-a, 0), and has the equation x + a = 0.The directrix of the parabola y^2 = -4ax, having x-axis, passes through (a, 0), and has the equation x - a = 0.The directrix of the parabola x^2 = 4ay, having y-axis as its axis, passes through (0, -a), and has the equation y + a = 0.The focus of the parabola x^2 = -4ay, having y-axis as its axis, passes through (0, a), and has the equation y - a = 0.Given:
-8(x-5)=(y+1)²
Now, using the definition of directrix
x= 8/4 +5
x= 2+ 5
x= 7

A football quarterback goes for a two-point conversion when the ball is within 10 yards of the end zone. During the game, he has two opportunities for a two-point conversion. He misses the first attempt 50% of the time. When he misses the first attempt, he misses the second attempt 15% of the time. What is the probability of missing both two-point conversion attempts?
Answer:
P = 0.075 P = 7.5%
Step-by-step explanation:
We pretty much look for the probability that the player fails the first attempt and also fails the second attempt.
We know for a fact that the probability that the quarterback fails the first attempt is:
p(1) = 0.5
and we know that the probability that the quarterback fails the second attempt after failing the first is:
p(2/1) = 0.15
Then the probability of failure of both attempts is:
P(2/1) = p(1 and 2) / p(1)
p(1 and 2) = P(1) * P(1/2)
p(1 and 2) = 0.5 * 0.15
and that is
p(1 and 2) = 0.075

You save $1400 from a summer job. You decide to put it into an account that earns simple annual interest. After 9 months, your balance is $1421. Find the annual interest rate.
Answer:
2%
Step-by-step explanation:
Calculate annual interest amount first:
annual interest x 9/12=21
Annual interest =21x12/9
annual interest amount=$28
calculate annual interest rate
1400 x interest rate = annual interest
$1400 x interest rate = $28
interest rate =$28/1400
interest rate=.02 or 2%
