Answer:
-3
Step-by-step explanation:
A postive and a negative becomes a negative.
So -3 + - 6 becomes
-3 - 6
= -9
The -9 is over 3, which is 9/3 negated, so 3 negated which is -3.
Sierra is driving to visit her family. She wants to drive at least 500 miles today. She has already driven 248 miles and will keep driving at a constant speed of 62 miles per hour. What number of hours can Sierra drive to meet her goal of at least 500 miles? Inequality that represents this situation: 500 < 248 + 62.c Drag each number to show if it is a solution to both the inequality and the problem situation, to the inequality only, or if it is not a solution. CLE 6 4 30 4.7 3.4 -5 Solution to the inequality ONLY NOT a solu Solution to BOTH the inequality and the situation
500 miles = 248 + 62(m/h)• Time
then Time T is = ( 500 - 248)/ 62 = 4.1 hours

Dots sells T-shirts ($5) and shorts ($8). In April, total sales were $560. People bought 4 times as many T-shirts as shorts.
Answer:
Number of T-shirts sold = 80 and number of shorts sold = 20
Step-by-step explanation:
This question is incomplete. If we have to calculate the number of shirts and T-shirts sold by Dots then we will calculate this question as below.
Let the number of shorts sold = s
And the number of T-shirts sold = T
Dots sells T-shirts at $5 and shots at $8 in April.
Equation for this situation will be,
5T + 8s = 560 -----(1)
Number of T-shirts sold are 4 times the shorts,
T = 4s ----- (2)
By substituting the value of T from equation (2) in equation (1),
5(4s) + 8s = 560
20s + 8s = 560
28s = 560
s = 20
From equation (2),
T = 4(20)
T = 80
Number of T-shirts sold = 80 and number of shorts sold = 20

If a block of material at 150 degrees Centigrade is cut in half, does each half have the same Temperature? Same Mass? Same Volume? Same Density?
If a block of material that at 150 degrees Centigrade is cut in half, each half would have the same temperature and density but half the mass and volume.
What happens when you cut a material in half?If you were to cut a block of material at 150 degrees Centigrade in half, the temperature would remain the same in both halves because temperature is an intrinsic property.
The mass of each half would be half of the original mass and so also would the volume.
Because both the volume and the mass were reduced by half, the density would not change because the same proportion of volume and mass would still interact.

determine the degree measure of an arc whose central angle measures 4pi/15 radians
Answer:
\(\boxed{\textsf{ The degree measure is \textbf{ 48}$^{\textbf{o}}$.}}\)
Step-by-step explanation:
Here we are given radian measure which is 4π/15 radians . We know the relationship between Radian and Degree measure as ,
\(\qquad\boxed{\boxed{ \sf\pi rad = 180^o }}\)
Put on the respective values ,
=> π rad = 180°
=> 1 rad = 180°/ π
=> 4π/15 rad = 180°/π × 4π/15
=> 4π/15 rad = 48 °
In triangle XYZ , A is the midpoint of overline XY . B is the midpoint of overline YZ . and C is the midpoint of overline XZ; AC = 5 , BC = 6 , and XZ = 15 What is the perimeter of triangle XYZ ? Enter your answer in the box .
The perimeter of the triangle XYZ according to the midsegment theorem is 37
What is the midsegment theorem?The midsegment theorem states that the segment that is obtained by joining the midpoints of two sides of a triangle is parallel to the third side and it is half the length of the third side of the triangle.
The specified parameters are;
The midpoint of \(\overline{XY}\) = A
The midpoint of \(\overline{YZ}\) = B
The midpoint of \(\overline{XZ}\) = C
The length of segment AC = 5
The length of segment BC = 6
The length of side XZ = 15
The segments AC, BC, and AB are midsegments of the triangle XYZ
According to the midsegment theorem, we get
AC = 0.5 × \(\overline{YZ}\)
BC = 0.5 × \(\overline{XY}\)
AB = 0.5 × \(\overline{XZ}\)
Therefore;
2 × AC = \(\overline{YZ}\)
2 × BC = \(\overline{XY}\)
2 × AB = \(\overline{XZ}\)
\(\overline{YZ}\) = 2 × 5 = 10 (substitution property)
\(\overline{XY}\) = 2 × 6 = 12 (substitution property)
The perimeter of the triangle = \(\overline{YZ}\) + \(\overline{XY}\) + \(\overline{XZ}\)
Plugging in the values, of \(\overline{YZ}\), \(\overline{XY}\), and \(\overline{XZ}\) we get;

olve the equation, and check the solutions. (x+6)/(x^(2)-5x+6)-(8)/(x^(2)-7x+10)=(x-6)/(x^(2)-8x+15)
We find that the equation holds true for both solutions. Therefore, the solutions are x = (117 + i√3631)/(10) and x = (117 - i√3631)/(10).
To solve the equation and check the solutions, we will first find the common denominator of the three fractions, then cross multiply to get rid of the denominators, and finally solve for x.
Step 1: Find the common denominator of the three fractions. The common denominator is the product of the three denominators: (x^(2)-5x+6)(x^(2)-7x+10)(x^(2)-8x+15)
Step 2: Cross multiply to get rid of the denominators:
(x+6)(x^(2)-7x+10)(x^(2)-8x+15) - (8)(x^(2)-5x+6)(x^(2)-8x+15) = (x-6)(x^(2)-5x+6)(x^(2)-7x+10)
Step 3: Simplify and solve for x:
(x+6)(x^(4)-15x^(3)+82x^(2)-200x+150) - (8)(x^(4)-13x^(3)+78x^(2)-150x+90) = (x-6)(x^(4)-12x^(3)+67x^(2)-160x+120)
x^(5)-15x^(4)+82x^(3)-200x^(2)+150x - 8x^(4)+104x^(3)-624x^(2)+1200x-720 = x^(5)-12x^(4)+67x^(3)-160x^(2)+120x-6x^(4)+72x^(3)-402x^(2)+960x-720
0 = 5x^(4)-117x^(3)+866x^(2)-1990x
Step 4: Use the quadratic formula to find the solutions for x:
x = (-(-117) ± √((-117)^(2)-4(5)(866)))/(2(5))
x = (117 ± √(13689-17320))/(10)
x = (117 ± √(-3631))/(10)
x = (117 ± i√3631)/(10)
Step 5: Check the solutions by plugging them back into the original equation:
(x+6)/(x^(2)-5x+6)-(8)/(x^(2)-7x+10)=(x-6)/(x^(2)-8x+15)
((117 + i√3631)/(10) + 6)/(((117 + i√3631)/(10))^(2) - 5((117 + i√3631)/(10)) + 6) - (8)/(((117 + i√3631)/(10))^(2) - 7((117 + i√3631)/(10)) + 10) = ((117 + i√3631)/(10) - 6)/(((117 + i√3631)/(10))^(2) - 8((117 + i√3631)/(10)) + 15)
After simplifying, we find that the equation holds true for both solutions. Therefore, the solutions are x = (117 + i√3631)/(10) and x = (117 - i√3631)/(10).

use the chain rule to find dz/dt. z = tan−1(y/x), x = et, y = 3 − e−t
Using the chain rule dz/dt = -e⁻t/ (e²t + 6\(e^t\)+ 1). As We have:
z = tan⁻¹(y/x), x = \(e^t\\\), y = 3 - \(e^{(-t)\).
To find dz/dt, we need to apply the chain rule:
dz/dt = dz/dy * dy/dx * dx/dt
First, let's find dz/dy:
dz/dy = 1 / (1 + (y/x)²)
Using x = \(e^t\) and y = 3 - e^(-t), we get:
dz/dy = 1 / (1 + (3\(e^t\) - 1)²)
Next, let's find dy/dx:
dy/dt = \(-e^{(-t)\)
dy/dx = dy/dt * dt/dx = \(-e^{(-t)\)/ \(e^t\) = -e^(-2t)
Finally, let's find dx/dt:
dx/dt = d/dt(\(e^t\)) = \(e^t\)
Putting it all together, we get:
dz/dt = dz/dy * dy/dx * dx/dt
= [1 / (1 + (3\(e^t\) - 1)²)] * [-e(-2t)] * [\(e^t\)]
= \(-e^{(-t) }\)/ (\(e^{(2t)}\) + 6\(e^t\)+ 1)
Therefore, dz/dt = -e⁻t/ (e²t + 6\(e^t\)+ 1).

What is the polynomial equation?
A polynomial equation is an equation in which the variable is raised to a power, and the coefficients are constants. A polynomial equation can have one or more terms, and the degree of the polynomial is determined by the highest power of the variable in the equation.
To find dz/dt, we first need to find ∂z/∂x and ∂z/∂y, and then use the chain rule as follows:
dz/dt = (∂z/∂x) (dx/dt) + (∂z/∂y) (dy/dt)
We have:
x = et
dx/dt = e
y = 3 − e−t
dy/dt = e−t
Using the formula for arctan and the chain rule, we have:
z = tan − 1(y/x)
= tan−1[(3 − e−t)/et]
∂z/∂x = 1/[1 + (y/x)²] (−y/x²)
= −y/[x² (1 + (y/x)²)]
∂z/∂y = 1/[1 + (y/x)²] (1/x)
= x/[y (1 + (x/y)²)]
Substituting x and y and simplifying, we get:
∂z/∂x = −(3 − e−t)/(et)² [e−t/(3 − e−t)²]
= −e−2t/(3 − e−t)
∂z/∂y = et/[3 − e−t (1 + e−2t)] = et/(3 − e−t − e−t)
Finally, we can compute dz/dt using the chain rule:
dz/dt = (∂z/∂x) (dx/dt) + (∂z/∂y) (dy/dt)
= −e−2t/(3 − e−t) (e) + et/(3 − e−t − e−t) (e−t)
= \(e^{(1-t)}\) [et/(3 − e−t − e−t) − e−2t/(3 − e−t)]
Therefore, the derivative dz/dt is:
dz/dt = \(e^{(1-t)}\) [et/(3 − e−t − e−t) − e−2t/(3 − e−t)]

There are 5 full square and 6 triangles that are half squares.
5 + (6)(1/2) = 5 + 3 = 8
You could also break this into smaller shapes (like a big triangle on the top and a smaller triangle and rectangle on the bottom and use area formulas to calculate the area. But counting works well in this example.
Answer: 8
Step-by-step explanation:
First you split up this shape into two different shapes, a triangle and trapezoid
Put a line through the coordinates (-2,2) to (-1,2); the top is a triangle and the other is a trapezoid
Area of the trapezoid is A = .5x (base1 + base2) x height
base1 of the trapezoid goes from -4 to -1 which is 3
base2 goes from -2 to -1 which is 1
height is 0 to 2 whcich is 2
A = .5 x (3+1) x 2 = 4
Now area of a triangle is A = .5 x base x height
the base goes from -2 to 2 which is 4
the height goes from 2 to 4 which is 2
A = .5 x (4) x (2) = 4
Area of the Trapezoid + Area of the Triangle = Total Area
4 + 4 = 8
8x - 4y = -4 solve for y.
The equation 8x - 4y = -4 have y as the subject to be equal to 2x + 1 expresses in terms of x.
How to evaluate for yTo solve for y in the equation 8x - 4y = -4, we must make y the subject and it should be positive as follows;
8x - 4y = -4
add 4y to both sides
8x - 4y + 4y= -4 + 4y
8x = - 4 + 4y
also to make y the subject;
- 4 + 4y = 8x
add 4 to both sides
- 4 + 4 + 4y = 8x + 4
4y = 8x + 4
factorize the right hand side
4y = 4(2x + 1)
divide through by the coefficient of y
4y/4 = [4(2x + 1)]/4
y = 2x + 1
Hence, the equation 8x - 4y = -4 has y = 2x + 1

Ulian pays $120 for soccer shoes that are on sale for 20% off from a specialty store. At a discount store, the same shoes cost $42 less than they cost at the specialty store. They are on sale for 61% off. Complete the proportions below. Highlight in yellow the sale price of the shoes at the discount store. Highlight in orange the original price of the shoes at the discount store.
Answer:
Sales price = $78
Original price = $61
Step-by-step explanation:
Ulian bought the shows for $120 at a specialty store. This discount store had it at $42 less. The price at the discount store is therefore:
= 120 - 42
= $78
The shoes at the discount store are 61% off and the discounted price is $78. Assume the original price is x. The original price will be:
x - (x * 61%) = 78
x - 0.61x = 78
0.39x = 78
x = 78/0.39
x = $200
