Step 1: Determine the area of the back
[tex]A = l * w[/tex]
[tex]A = 10\ units * 13\ units[/tex]
[tex]A = 130\ units^2[/tex]
Step 2: Determine the hypotenuse
Pythagorean theorem → [tex]a^2 + b^2 = c^2[/tex]
[tex](10-6)^2\ units + 7^2\ units = c^2[/tex]

Suppose for some value of x the solution to the equation 2.5(y−x)=0 is y = 6. What must be true about x?
HELPPPPPPPPPP
The value of the expression inside the parentheses must be equal to
Answers
Step-by-step explanation:
In this case, you input the value of y (y = 6) into the equation ( 2.5(y-x)= 0)
2.5(6-x) = 0
Open the bracket,
(2.5×6)-2.5x= 0
Collect like terms.
2.5x= 2.5×6
Divide both sides by the coefficient of x (2.5)
x = 6
So,
x= 6 is true.
.
Substituting 6 for x in the equation,
2.5(6-6)= 0
2.5•0 = 0
0= 0
Which is also true.

Answers
The difference in the pay rate of Phoebe in 5 years will be $11850
How to calculate the pay?Your information is incomplete. Therefore, an overview will be given. Let's assume that the pay rate is $20000. When there is a 5% increase, the new pay rate will be:
= $20000 + (5% × $20000)
= $20000 + $1000
= $21000
When there is $0.75 increase per hour, the new pay rate on 5 years will be:
= (0.75 × 43800)
= $32850
The difference will be:
= $32850 - $21000
= $11850

Answers
Answer:
900 - 60n ≥ 450
n ≤ 7.5
Answer: 7 weeks
Step-by-step explanation:
Let n = numberof weeks.
In n weeks, you withdraw 60n from the account.
After withdrawing $60 for n weeks, teh amount must be at least $450. At least $450 means greater than or equal to $450.

What is the standard deviation of the data? 0.5 1.5 2.0 2.5
Answers
Answer:
0.74
Step-by-step explanation:
The standard deviation of a data set is the sqaure root of the variance, so first we must find the variance. The equation for variance is:
σ² = [tex]\frac{{(x_{1}-[x bar] )}^{2}+...+{(x_{n}-[x bar]) }^{2}}{n}[/tex]
x = number in the data set
xbar = median of the data set
n = number of terms
Plugging in the given values, the equation for the variance of this number set is:
σ² = [tex]\frac{(0.5 - 1.625)^{2} + (1.5 - 1.625)^{2}+ (2.0 - 1.625)^{2}+(2.5 - 1.625)^{2} }{4}[/tex]
Solving:
= [tex]\frac{1.265625+0.015625+0.140625+0.765625}{4}[/tex]
= [tex]\frac{2.1875}{4}[/tex]
σ² = 0.546875
Since the standard devianation is the sqaure root of the variance, we'll sqaure 0.546875:
[tex]\sqrt{0.546875}[/tex]
= 0.73950997288745
= 0.74 (rounded)

Here : a = 5, b = 8, and h = 5Area = 1/2 x (5 + 8) x 5Area = 1/2 x 13 x 5Area = 65/2Area = 32.5 square feetAnswer:
32.5 square feet
Step-by-step explanation:
here we just find the area of both shapes within the trapezoid and add them, let's start with the triangle,
formula for the area of a triangle is 0.5 × base × height
therefore,
the area of the triangle is 7.5
the area of a square is equal to the length of the side squared.
5^2 = 25
the sum of 25 + 7.5 = 32.5

What is the gcf of 36 and 90
Answers
Since both are even numbers, choose an even number that both divide by.
Like 6
36/6 = 6
90/6 = 15
Can you factor 6 and 15 even more? Yes, by 3
6/3 = 2
15/3 = 5
Can you factor 2 and 5? No, that’s it.
So GCF is 6 * 3 = 18
Lets check:
36/18 = 2
90/18 = 5
Can you factor 2 and 5 even further? No, that’s it
So GCF is indeed 18

An expression has numbers, variables, and mathematical operations. The representation of Leroy's total employment compensation is $46,650.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
As it is given that Leroy's total job benefits were $50,150. while his total job expenses for traveling and for professional development for the year were $3,500. As the total employment compensation is the amount that is the difference between job benefits and job expenses. Therefore,
[tex]\rm Total\ employment\ compensation= Job\ benefits + Job\ expenses[/tex]

Answers
The probability of a late departure or an early arrival P(late departure or early arrival) = 0.12 + 0.27 – 0.04
What is probability?
The probability is defined as the chances of occurence of any event from the sample.
Given: The probability of a late departure is 12 %t, the probability of early arrival is 27%.
i.e. P(late departure)=0.12
P(an early arrival)=0.27
The probability of both a late departure and an early arrival is 4 percent.
P(late departure and early arrival) =0.04
Now, using the formula the probability of the union of two dependent events A and B:-
[tex]\rm P(AUB)=P(A)+P(B)-P(A \cap B)[/tex]
i.e. P(late departure or early arrival) = P(late departure)+P(an early arrival)-P(late departure and early arrival)
=0.12+0.27-0.0.04
Hence, the required equation : P(late departure or early arrival) = 0.12 + 0.27 – 0.04

https://brainly.com/question/24756209
The equation that shows how to correctly calculate the probability of a late departure or an early arrival is P(L∪E)=0.12+0.27-0.04.
Probability of late departure P(L) = 0.12
Probability of early arrival P(E) = 0.27
Probability of both a late departure and an early arrival P(L∩E)= 0.04
What is probability?Probability is the measurement of the likelihood of an event.
P(L∪E)=P(L)+P(E)- P(L∩E)
Where P(L∪E) is the probability of a late departure or an early arrival.
So, P(L∪E)=0.12+0.27-0.04
Hence, the equation that shows how to correctly calculate the probability of a late departure or an early arrival is P(L∪E)=0.12+0.27-0.04.

Answer:
0.69
Step-by-step explanation:
In a right triangle, the cosine of one of the acute angles is the ratio of the adjacent ("next to") side to the hypotenuse.
In this triangle, the side adjacent to angle T has length [tex]\sqrt{38}[/tex]. Now you need the length of the hypotenuse, ST. Use the Pythagorean Theorem:
[tex]ST^2=(\sqrt{38})^2+(\sqrt{41})^2 \\\\ST^2=38+41\\\\ST=\sqrt{79}[/tex]
Build the ratio (adjacent) / (hypotenuse) and approximate it with a decimal.
[tex]\cos{T}=\frac{\sqrt{38}}{\sqrt{79}} \approx 0.69[/tex]
[tex]{\large{\red{\mapsto{\maltese{\underline{\green{\boxed{\blue{\underbrace{\overbrace{\pink{\pmb{\bf{Answer:}}}}}}}}}}}}}}[/tex]
To find :-
Cos T = ?
Given :-
Perpendicular(P) = RS = √41
Base(B) = RT = √38
Formula to be used :-
We will use here a trignometry formula to find hypotenuse (H) which is ST.
(hypotenuse)² = (perpendicular)² + (base)²
[tex] \cos(A) = \frac{base}{hypotenuse} [/tex]
Solution:-
H² = P² + B²
H² = (√41)² + (√38)²
H² = 41 + 38
H² = 79
H = √79
[tex] \cos(T) = \frac{B}{H} \\ \cos(T) = \frac{ \sqrt{38} }{ \sqrt{79} } \\ \cos(T) = \frac{6.17}{8.89} \\ \cos(T) = 0.69[/tex]
Result :-
The value of cos(T) is 0.69.

What is projectile motion?Projectile motion is the motion of an object thrown or projected into the air, subject to only the acceleration of gravity. The object is called a projectile, and its path is called its trajectory
Projectile motion
We are told that the projectile motion of an object can be modeled using;
h(t) = gt² + v0*t + h0
Where;
g is the acceleration due to gravity
t is the time since launch
h(t) is the height of the projectile after time t
v0 is the initial velocity
h0 is the initial height.
Now, we are given;
The acceleration due to gravity; g = –9.8 m/s²
Initial velocity; v0 = 20 m/s
Initial height; h0 = 60 m
Hence solution can be simplified to determine when the object will hit the ground is; h(t) = -9.8t² + 20t + 60 h(t) = -9.8t² + 20t + 60

To find y will look to eliminate x:
- 6x + 2y = - 18
- 3x - 2y = 54 (multiply both sides by -2)
- 6x + 2y = - 18
6x + 4y = - 108
