Jayden has $20.56. He buys an apple for $0.79 and a granola bar for $1.78. How much money does Jayden have now? A
$2.57
B
$17.99
C
$18.01
D
$23.13
Answer:
B:
$17.99
Step-by-step explanation:
Add the total amount spent: $0.79 (apple)+ $1.78 (granola bar)=$2.57
Subtract from the money Jayden has: $20.56-$2.57=$17.99

Write [tex]cot^{2} x (1+tan^{2} x)[/tex] Then simplify the expression so no quotients appear
Step-by-step explanation:
From Trig
1 + tan²x = Sec²x
Also
Sec²x = 1/cos²x
Now
Cot²x = 1/tan²x = cos²x/sin²x
Putting all together
Cot²x(1+tan²x)
= Cot²x(sec²x)
= cos²x/sin²x(1/cos²x)
cos²x on the numerator and that one the denominator cancels out
we have
= 1/sin²x
From Trig
1/sin²x = cosec²x
So Our Answer = cosec²x.

Scott strikes out at bat 36% of the time. Find the probability that he strikes out no more than three times on his next eight times at bat.
Answer:
68.47%
Step-by-step explanation:
The answer is 68.47%
Solution -
We know that,
The binomial formula is -
P(x) = [tex]^{n}C_{x}p^{x}q^{n-x}[/tex]
where
n is the number of trials
x is the strike out number.
p is the probability of success
q is the probability of failure
Here,
n = 8
p = 36% = 0.36
q = 1 - 0.36 = 0.64
Now,
We want to find the probability that he strikes out no more than 3 times (i.e. <= 3.)
So,
We need to check the cases where x = 0, 1, 2 and 3.
Now,
For x = 0,
P(0) = [tex]^{8}C_{0}(0.36)^{0}(0.64)^{8-0}[/tex] = (0.64)⁸
P(1) = [tex]^{8}C_{1}(0.36)^{1}(0.64)^{8-1}[/tex] = 8×0.35×0.64⁷ .
P(2) = [tex]^{8}C_{2}(0.36)^{2}(0.64)^{8-2}[/tex] = 28×0.35² ×0.64⁶ .
P(3) = [tex]^{8}C_{3}(0.36)^{3}(0.64)^{8-3}[/tex] = 56×0.35³ ×0.64⁵ .
So,
Probability that he strikes out no more than three times = P(0) + P(1) + P(2) + P(3) = 68.47%
At track practice, Coach Wilson told the team to split into groups of four for a special relay. The first runner had to run 1 lap around the track (440 yards). The second runner had to run 2 laps around the track. The third runner had to to run 3 laps around the track. The final runner had to run 4 laps around the track (1 mile). How many yards did each relay team team have to run altogether? *

It's the 3rd picture. -3 1/4 + 4 3/4 = 1 1/2
Step-by-step explanation:
the answer choice are -6, 9, 7, 15
Step-by-step explanation:
the answer is 7 because there are seven spaces in between
Answer:
The Distance = √(y2-y1)² + (x2-x1)²
Notice
The points occur at the same x value (-6)
So We don't have to both about this cos the change will be zero(x2-x1)
Why?
(-6-(-6) = 0.
So we're concerned with the y value
y1= -2
y2= -9
(y2-y1) = -9-(-2) = -9+2 = -7
d= √(-7)²
= √49
=7.
The Third Option is correct.

At noon, the temperature at a mountaintop research center is 11 degrees. Overnight the temperature drops to -19 degrees. Which expression represents how much the temperature changed?
Answer:
ΔT = ( -19°C - 11°C) = -30°C
Step-by-step explanation:
When we have a given variable, let's call it X, the change of X in a given interval is written as:
ΔX = (X₂ - X₁)
Where:
X₂ = final value of the variable
X₁ = initial value of the variable.
In this case, we have the temperature, and we know that the initial temperature is 11°C, then:
T₁ = 11°C
While the final temperature is -19°C, then:
T₂ = -19°C
Then the change will be:
ΔT = ( -19°C - 11°C) = -30°C
This is the wanted expression.

During the clearance sale the store discounted all jewelry 1/4. What is the discount on a $19.96 bracelet
Answer: $4.99
Step-by-step explanation:
The store discounted all jewelry by 1/4 which means that they removed 1/4 of the price of an item off of it.
The discount on a $19.96 bracelet would therefore be:
= 1/4 * 19.96
= $4.99
This means that the item will sell for:
= 19.96 - 4.99
= $14.97

Find the length of the arc.
Answer:
18.84 ft
Step-by-step explanation:
¼×2×3.14×12 = 18.84 ft
Step-by-step explanation:
assuming 90° is the central angle measure then the degree measure of the arc would be 90°
though the question asks for length
to do this create a ratio of the degree measurement of the arc divided by the total degree measure of a circle which would be
90/360
next think about circumference, it's the measure of the length around a circle. that would be relevant to what the question is asking so calculate it the formula is C=2*pi*r
calculate and the circumference is 24pi
next multiply the total circumference by the ratio for the section we want in this case 90/360
arc length = 24pi * 90/360 = 6pi
therefore the answer is 6pi or 18.84 substituting 3.14 for pi
Write the ratios for sin X and cos X.
Answer:
[tex] \sin(X) = \frac{ \sqrt{119} }{12} \: , \: \cos(X) = \frac{5}{12} [/tex]
Answer:
Its the last choice.
Step-by-step explanation:
sin X = opposite side / hypotenuse
= √119/12.
cos X = adjacent side / hypotenuse
= 5/12.

5x + 15y = 5
The solution is ( , )
Answer:
x=4, y=-1. (4, -1).
Step-by-step explanation:
x+5y=-1
5x+15y=5
---------------
-5(x+5y)=-5(-1)
5x+15y=5
--------------------
-5x-25y=5
5x+15y=5
----------------
-10y=10
y=10/-10
y=-1
x+5(-1)=-1
x-5=-1
x=-1+5
x=4
