Answer:
$7.38
Step-by-step explanation:
Let's start out with variable x, representing his original $286
y will represent his balance after his order ($182.06)
a is our variable for our one-time $8 shipping fee
b will represent the cost of one card
our equation is => ((x - a) - y) ÷ 13 = b
Substitute => ((286 - 8) - 182.06) ÷ 13 = b
Solve => (278 - 182.06) ÷ 13 = b
95.94 ÷ 13 = b
b = 7.38
Thus, our answer is $7.38 per card

Answer:
200.96ft^2
Step-by-step explanation:
Diameter of the circular area of grass that the sprinkler sprays with water is 16 feet.
Divide the diameter by 2 to get its radius
Radius of the circle = Diameter of the circle / 2
so, 16 feet / 2 = 8 feet
Area of the circle is π times the square of the radius
Area of the circle = π × r² = 3.1415 × 8 feet = 201.056 square feet.
Closest answer will be 200.96ft^2

Step-by-step explanation:
Willa and her friend decide to hang out at her friend’s house after basketball practice on Friday to listen to a new album by their favorite band. They have a great time listening to the music and Willa deliberately ignores texts from her dad. When she gets home, her dad is really upset with her. He didn’t know where she was. He has a rule that he needs to know where she is and that she has to ask permission before she goes anywhere. Willa thinks that since she’s in eighth grade, she shouldn’t have to do this anymore. Her dad should trust her more. Willa tells her dad that she’s not a little kid anymore and storms off to her room and slams the door.

which statement is true about the extreme value the given quadratic equation? y = -3x^2 + 12x - 33 Oa. The equation has a maximum value with a y coordinate of -27 Ob. The equation has a minimum value with a y coordinate of -21 Oc. the equation has a minimum value with a y coordinate of -27 Od. The equation has a maximum value with a y coordinate of -21
Answer:
D. The equation has a maximum value with a y coordinate of -21Step-by-step explanation:
The quadratic equation has the extreme value at vertex with x-coordinate of
x = -b/2aFor the given equation the vertex is:
x = -12/2(-3) = 2The value of y at x = 2 is:
y = -3(2²) + 12(2) - 33 = -12 + 24 - 33 = -21Since the leading coefficient is negative, the extreme is the maximum for the given equation.
Correct choice is D
Help me out, please!! Find the value of x in the given right triangle
Answer:
x ≈ 44.4°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin x = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{7}{10}[/tex] , then
x = [tex]sin^{-1}[/tex] ([tex]\frac{7}{10}[/tex] ) ≈ 44.4° ( to the nearest tenth )
determine the measure of each angle. 4x - 90= ? Degree
Answer:
4x - 90= 90
Explain:
Simplifying
(4x + -90) = 90
Reorder the terms:
(-90 + 4x) = 90
Remove parenthesis around (-90 + 4x)
-90 + 4x = 90
Solving
-90 + 4x = 90
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '90' to each side of the equation.
-90 + 90 + 4x = 90 + 90
Combine like terms: -90 + 90 = 0
0 + 4x = 90 + 90
4x = 90 + 90
Combine like terms: 90 + 90 = 180
4x = 180
Divide each side by '4'.
x = 45
Simplifying
x = 45

The diargram show a right show a right -angle and a parallelogram the area of the parallelogram is times the area of the traiangle and its perpendicular height is h cm find the value of h
Question:
The diagram shows a right -angle and a parallelogram. The area of the parallelogram is 5 times the area of the triangle. The perpendicular height of the parallelogram is h. Find h
Answer:
[tex]h =12cm[/tex]
Step-by-step explanation:
Given
Triangle
[tex]Base = 9cm[/tex]
[tex]Height = 16cm[/tex]
Parallelogram
[tex]Base = 30cm[/tex]
[tex]Height = h[/tex]
Calculate the area of the triangle
[tex]Area = 0.5 * Base * Height[/tex]
[tex]Area = 0.5 * 9cm * 16cm[/tex]
[tex]Area = 72cm^2[/tex]
When multiplied by 5, gives the area of the parallelogram.
So:
The area of Parallelogram is:
[tex]Area = Base * Height[/tex]
[tex]Area = 30cm * h[/tex]
This gives:
[tex]30cm * h = 72cm^2 * 5[/tex]
Make h the subject
[tex]h = \frac{72cm^2 * 5}{30cm}[/tex]
[tex]h = \frac{72cm^2}{6cm}[/tex]
[tex]h =12cm[/tex]

At a sale, suits were sold for $72 each. This price was 45% of a suit's original price. How much did a suit originally cost?
Answer:
$160
Step-by-step explanation:
Let the original cost of suit be x
If the suits were sold for $72 each and this price was 45% of a suit's original price, then;
72 = 45% of x
72 = 0.45x
x = 72/0.45
x = 160
Hence the original price of the suit is $160
Answer:
160
