Step-by-step explanation:
174 + 10x = 102 + 10x - 6x
174 - 102 = 10x - 6x -10x
72 = - 6x
- x = 72/6
- x = 12
x = -12
A rectangle has dimensions 8 1/5 in by 13 in. A diagonal of the rectangle forms two matching right triangles. What is the area of one of the triangles.
The area of one of the triangle is ____ in.
Answer:
53.3 in^2
Step-by-step explanation:
Given data
Base B= 13in
Height H= 8 1/5 in= 41/5in
The expression for the area of a triangle is
Area= 1/2 Base * Height
Substitute
Area= 1/2* 13* 41/5
Area= 6.5*41/5
Area= 266.5/5
Area= 53.3 in^2
Hence the area is 53.3 in^2
Q1. Prasha has five blocks of wood. The total weight of all five blocks of wood is 3 kilograms. 4 of the blocks of wood each have a weight of 650 grams. Work out the weight, in grams, of the other block of wood.
Answer: Weight of the remaining block of wood =400g
Step-by-step explanation:
Total Weight of five(5) blocks = 3kg = 3000g
Weight of 4 out of the 5 blocks = 650x 4= 2600g
Weight of the remaining block of wood =Total Weight of five(5) blocks-Weight of 4 out of the 5 blocks
= 3000g-2600g
=400g

What is the volume of this birdfeeder? Round to the nearest tenth (if possible)
Answer:
14 in^3.
Step-by-step explanation:
The volume = volume of the bottom prism + volume of the top pyramid
= area of base * height of the prism + 1/3 * area of base * height of the pyramid
= 2 * 1.5 * 4 + 1/3 * (2*1.5) * 2
= 3*4 + 1/3 * 6
= 14 in^3.

The hydrogen ion concentration (h+) in a certain cleaning compound is (h+)=3.2x10^-11 use the formula ph=-log(h+) to find the pH of the clean compound the pH is approximately
Answer:
The [tex]pH[/tex] of the clean compound is approximately 10.495.
Step-by-step explanation:
If the cleaning ion concentration of the cleaning compound is [tex][H^{+}] = 3.2\times 10^{-11}[/tex], then the [tex]pH[/tex], no unit, of the compound is:
[tex]pH = -\log_{10} [H^{+}][/tex] (1)
[tex]pH = -\log_{10} (3.2\times 10^{-11})[/tex]
[tex]pH = -\log_{10} 3.2 - \log_{10} (10^{-11})[/tex]
[tex]pH = -\log_{10} \frac{32}{10} +11[/tex]
[tex]pH = -\log_{10} 32 + \log_{10} 10 + 11[/tex]
[tex]pH = -\log_{10} 32 +12[/tex]
[tex]pH \approx 10.495[/tex]
The [tex]pH[/tex] of the clean compound is approximately 10.495.

Answer:
(3) y = (x -3)²
Step-by-step explanation:
Try the first value of x in each function:
(1) y = 3² -3 ≠ 0
(2) y = (3 +3)² ≠ 0
(3) y = (3 -3)² = 0 . . . . . . matches the table value for f(3)

In quadrilateral ABCD, AD ∥ BC. Quadrilateral A B C D is shown. Sides A D and B C are parallel. The length of A D is 3 x + 7 and the length of B C is 5 x minus 9. What must the length of segment AD be for the quadrilateral to be a parallelogram? 8 units 16 units 31 units 62 units
Answer:
31 units
Step-by-step explanation:
Given
[tex]AD = 3x + 7[/tex]
[tex]BC = 5x - 9[/tex]
Required
Find
If AD parallel to BC, then:
[tex]AD = BC[/tex]
This gives:
[tex]3x + 7 = 5x - 9[/tex]
Collect like terms
[tex]3x- 5x = -7-9[/tex]
[tex]-2x = -16[/tex]
Solve for x
[tex]x = 8[/tex]
Substitute [tex]x = 8[/tex] in [tex]AD = 3x + 7[/tex]
[tex]AD = 3 * 8 + 7[/tex]
[tex]AD = 31[/tex]

Answer: 1. 34 degrees+34 degrees=68 180-68=112 so x=112 degrees
2. 84+22=106 180-106=74 so x=74 degrees
3. 126+20=146 180-146=34 so x=34 degrees
4. both angles on both sides are 40 so 40+40=80 180-80=100 so x=100 degrees

HEY CAN ANYONE PLS ANSWER DIS MATH PROBLEM!
2/3p= 60? Step-by-Step explanation would be appreciated!
Answer:
p=90
Step-by-step explanation:
Divide 2/3 on both sides. When you divide a fraction, you actually
multiply by its reciprocal, or opposite (3/2).
2/3p=60
*3/2 *3/2
p=180/2
p=90
Hope this helps and have a great day C:
Answer:
p = 1/90
Step-by-step explanation:
determine the defined range
2/3p = 60, p = 0
then multiply both sides of the equation by 3p
2 = 180p
swap both sides of the equation
180p = 2
then Divide both sides of the equation by 180
p = 1/90 p = 0
check the solution is it in the defined range
then you should get your answers

Step-by-step explanation:
A navy cruiser detects a nuclear submarine that is 2500 feet from the cruiser. The angle between the water level and the submarine is 15.5 degrees. How deep is the submarine?
Answer:
Depth of the submarine = 668.09 feet
Step-by-step explanation:
From the figure attached,
In triangle ABC,
Distance between a navy cruiser and a nuclear submarine = 2500 feet
Angle between the water level and the submarine = 15.5°
By applying sine rule in the given triangle,
sin(∠BAC)° = [tex]\frac{BC}{AC}[/tex]
sin(15.5°) = [tex]\frac{BC}{2500}[/tex]
BC = 2500[sin(15.5)]
BC = 668.09 feet
Therefore, submarine is 668.09 feet deep in the sea.

Find value of x pleaseee
Answer:
Step-by-step explanation:
you can use the side angle side formula ( a form of Law of Cosines)
a^2 = b^2 + c^2 − 2bc cos(A)
where x = a , then
[tex]x^{2}[/tex] = [tex]5^{2}[/tex] +[tex]3^{2}[/tex] - 2*5*3*cos(107)
[tex]x^{2}[/tex] = 25 + 9 - 30 * (-0.292371)
[tex]x^{2}[/tex] = 25 + 9 -8.7711511
x = 5.0228 cm
