Answer:
x = 34
Step-by-step explanation:
The two angles sum to a right angle, which is 90 degrees. We can tell this from the box in the corner
x+56 = 90
Subtract 56 from each side
x+56-56= 90-56
X = 34
Answer:
x=34
Step-by-step explanation:
The angles are complementary, or they add to 90 degrees. We know this because of the little rectangle in the corner.
x+56=90
Subtract 56 from both sides
x+56-56=90-56
x=34

Maya should first isolate the variable [tex]\( x^2 \)[/tex] before completing the square.
The steps to solve the quadratic equation [tex]\( 4x^2 + 16x + 3 = 0 \)[/tex] by completing the square are as follows:
1.*Isolate the variable - To do this, Maya should move the constant term to the other side of the equation by subtracting 3 from both sides:
[tex]\[ 4x^2 + 16x = -3 \][/tex]
2. Factor out the coefficient of -The coefficient of x² is 4. Factor out 4 from the terms involving x
[tex]\[ 4(x^2 + 4x) = -3 \][/tex]
3. Complete the square To complete the square, Maya should add the square of half the coefficient of x t both sides of the equation. Half of 4 is 2, and [tex]\( (2)^2 = 4 \),[/tex]so she should add 4 to both sides:
[tex]\[ 4(x + 2)^2 = 1 \][/tex]
After completing these steps, Maya can proceed to solve the equation by isolating x and taking the square root.

Please help me! A soup can, shaped like a cylinder, has a diameter of 3.5 inches and a height of 5 inches. Each serving of soup is 15 cubic inches. If a can of soup this size costs $1.99, what is the cost for each serving of soup? Round to the nearest cent.
The cost for each serving of soup is $0.62
Step-by-step explanation:
Diameter =3.5 inches
Radius = 1.75 inches
Height = 5 inches
Each serving of soup = 15 cubic inches
Cost of the can = $1.99
Volume of the can = π(1.75 x 1.75) 5
= (3.14) (3.0625) 5
= 48.08 cubic inches
For 48 cubic inches of soup the cost is $1.99
For 15 cubic inches of soup the coat will be,
Cost = (15x1.99) /48
= $0.62
The cost for each serving of soup is $0.62
Final answer:
Calculate the volume of the soup can and determine the cost for each serving by dividing the total cost by the volume per serving. The cost per serving of soup is approximately $0.62.
Explanation:
To find the volume of the soup can:
Calculate the radius by dividing the diameter by 2: 3.5 inches / 2 = 1.75 inches.Use the formula for the volume of a cylinder: V = πr²hSubstitute the values to find the volume: V = 3.142 × (1.75 inches)² × 5 inches ≈ 48.32 cubic inchesTo find the cost per serving:
Divide the cost of the can by the total volume: $1.99 / 48.32 ≈ $0.041 per cubic inch.Multiply the cost per cubic inch by the volume per serving: $0.041 x 15 cubic inches ≈ $0.62Therefore, the cost for each serving of soup is approximately $0.62, rounded to the nearest cent.

This equation shows how the number of chocolates Josie has left is related to the number of gift baskets she assembles.
c = –9g + 97
The variable g represents the number of gift baskets she assembles, and the variable c represents the number of chocolates she has left. Up to how many gift baskets can Josie assemble and still have 16 chocolates left?
Josie can assemble 9 gift baskets
From the question, we are to determine up to how many gift baskets Josie can assemble and still have 16 chocolates left
To do this,
Simply substitute c = 16 in the equation and solve for g
The given equation is:
c = –9g + 97
Substitute c= 16:
c = –9g + 97
16 = -9g + 97
9g = 97 - 16
9g = 81
Divide both sides by 9:
g = 81/9
g = 9

Find the value of x.
m∠IHG = 162°
m∠IHK = (4x + 4)°
m∠KHG = (8x + 2)°
Final answer:
The value of x is 1.
Explanation:
To find the value of x in the given question, we need to set up an equation involving the angles.
From the information given, we have:
m∠IHG = 162°
m∠IHK = (4x + 4)°
m∠KHG = (8x + 2)°
We can set up an equation based on the relationship between the angles:
m∠IHG + m∠IHK + m∠KHG = 180°
Substituting the given angle measures, we have:
162° + (4x + 4)° + (8x + 2)° = 180°
Combine like terms:
12x + 168 = 180
Subtract 168 from both sides:
12x = 12
Divide both sides by 12:
x = 1
Therefore, the value of x is 1.
In a circle, a chord of 50 cm bisects a chord of 40 cm. Find the length of the longer segment of the 50 cm chord.
Answer:
The length of the longer segment of the 50 cm chord = 40
Step-by-step explanation:
let the length of the longer segment of the 50 cm chord = x
so, the other segment = 50 - x
A chord of 50 cm bisects a chord of 40 cm
using the Intersecting Chords Theorem
so, x(50-x) = 20 * 20
50x - x² = 400
x² - 50x + 400 = 0
(x - 40)(x - 10) = 0
x = 40 or x = 10
So, the the length of the longer segment of the 50 cm chord = 40
Answer:
23cm
Step-by-step explanation:
In the circle below, AB, CD, and EF are the chords of the circle. Chord CD is the diameter of the circle.
= 2√ (142−82)
= 2√ (196 − 64)
= 2√ (132)

Parallel lines e and f are cut by transversal b.
Horizontal and parallel lines e and f are cut by transversal b. At the intersection of lines b and e, the uppercase right angle is (2 x + 18) degrees. At the intersection of lines b and f, the top right angle is (4 x minus 14) degrees and the bottom right angle is y degrees.
What is the value of y?
16
50
130
164
Answer:
130
Step-by-step explanation:
e // f
2x + 18 = 4x - 14
2x = 32
x = 16
y = 180 - (4x - 14) = 180 - (64 - 14) = 130
Using the congruency of the top-right angles, it is found that the value of y is of 130.
---------------------
When two parallel lines are cut by a transversal, the top-right angles are congruent, that is, they have the same measure.In this question, their measures are of (2x + 18)º and (4x - 14)º. Thus, with this, we can find x:[tex]4x - 14 = 2x + 18[/tex]
[tex]2x = 32[/tex]
[tex]x = \frac{32}{2}[/tex]
[tex]x = 16[/tex];
Thus, the measure of the top right angles is given by, in degrees: [tex]4x - 14 = 4(16) - 14 = 64 - 14 = 50[/tex]---------------------
The top-right and the bottom-right angles are supplementary, that is, the sum of their measures is 180º.The measure of the top-right angle is of 50º.The measure of the bottom-right angle is of y.Thus:
[tex]y + 50 = 180[/tex]
[tex]y = 130[/tex]
The value of y is of 130.

386.9 ft2
593.8 ft2
639.4 ft2
1,053.2 ft2
Answer:
B - 593.8 ft2
Step-by-step explanation:
I also just finish the quiz and got the question right.
To find the base: 10 x 18 = 180
There are 4 lateral face, two each are conguent:
18 x 14.1 = 253.8
253.8 divided by 2 = 126.9
126.9 x 2 = 253.8
Other conguent sides:
10 x 16 = 160
160 divided by 2 = 80
80 x 2 = 160
Finally: 180 + 253.8 + 160 = 593.8 ft2
The required surface area of the rectangular pyramid is 593.8 ft². Therefore, the correct answer is option B.
What is surface area?The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.
As mentioned in the question, the rectangular pyramid has a rectangular base with dimensions of 18 ft by 10 ft, and four triangular faces. Two of the triangular faces have a base of 18 ft and a height of 14.1 ft, while the other two have a base of 10 ft and a height of 16 ft.
The area of the rectangular base is:
18 ft × 10 ft = 180 ft²
The area of each of the triangular faces is:
(1/2) × base × height
For the first two triangles:
(1/2) × 18 ft × 14.1 ft = 126.9 ft² each
For the second two triangles:
(1/2) × 10 ft × 16 ft = 80 ft² each
The total surface area of the rectangular pyramid is:
180 ft² + 126.9 ft² + 126.9 ft² + 80 ft² + 80 ft² = 593.8 ft²
So, the surface area of the rectangular pyramid is 593.8 ft². Therefore, the correct answer is option B.

If a 40-foot tall ladder is placed 15 feet from the base of a house, how high up the house will the
ladder reach?
Answer:
36.66 ft
Step-by-step explanation: You have to use the pythagorean theorem. a^2 + b^2 = c^2 (if you lean a ladder against a wall, it will make the shape of a triangle) The hypoteneuse would be 40 feet as it is the height of the ladder (the longest side). The one of the legs would be 15 ft (how far it is from the base of the house). You would then just plug the numbers in : a^2 + 15^2 = 40^2
a^2 + 256 = 1600
a^2 = 1344
a = 36.66
Drag the correct steps into order to solve the equation -7x + 14 = 56 for x.
Answer:
-7x + 14 = 56
Subtract 14 both sides
-7x + 14 - 14 = 56 - 14
-7x = 42
Divide both sides by -7
(-7x)/(-7) = 42/(-7)
x = -6
To solve for x, you need to isolate/get the variable "x" by itself in the equation:
-7x + 14 = 56 Subtract 14 on both sides
-7x = 42 Divide -7 on both sides to get "x" by itself
x = -6
