A triangle has side lengths 3.4 cm, 4 cm, and 5.2 cm. The angle measures are 40°, 50°, and 90°.
What type of triangle is this triangle?
acute scalene
right isosceles
acute isosceles
right scalene
Answer:
right isosceles I'm pretty sure
The solution is Option D.
The triangle is a right scalene triangle
What is a Scalene Triangle?A scalene triangle is a type of triangle with three different length sides and three interior angles that add up to 180 degrees. Scalene triangles have no equal of parallel sides , hence there is no line of symmetry. The interior angles of a scalene triangle can be acute , right or obtuse angles.
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
The measures of the sides of the triangles are 3.4 cm , 4 cm and 5.2 cm
The measures of angles of triangle are 40°, 50°, and 90°
Since the triangle is having all its length and sides different , it is a scalene triangle
Now , For a right angle triangle
hypotenuse² = base² + height²
( 5.2 )² = ( 3.4 )² + ( 4 )²
( 5.2 )² = 11.56 + 16
( 5.2 )² = 27.56
Hence , the triangle is a right scalene triangle

4x - 2y = -2 6x + 3y = 27
Answer:
Step-by-step explanation:
4x - 2y = -2 ------------------(I)
6x + 3y = 27 ------------------(II)
Multiply (I) by 3 & multiply (II) by 2
(I)*3 12x - 6y = -6
(II)*2 12x + 6y = 54 { Now add & y will be eliminated}
24x = 48
x = 48/24
x = 2
Plugin the value of x in equation (I)
4*2 - 2y = - 2
8 - 2y = -2 {subtract 8 from both side}
-2y = -2 - 8
-2y = -10 {Divide both sides by -2}
y = -10/-2
y = 5

A rectangular prism has a volume of 720 cubic units. How many unit cubes would fill the volume of the solid if they were packed without any gaps or overlaps?
Answer: 720 I think
Step-by-step explanation: Because if there are 720 cubic units, you can only fit 720.
There will be 720 cubes of side 1 unit that fill the prism if they were packed without any gaps or overlaps.
What is volumes?Volume is defined as the space occupied within the boundaries of any three-dimensional solid.
Given that, a rectangular prism has a volume of 720 cubic units, we need to find that, how many unit cubes would fill the volume with the solid if they were packed without any gaps or overlaps,
So, to find the same, we will divide the volume of the prism by the cube.
Volume of the cube = side³ = 1³ = 1
Therefore, number of cubes to be fitted = 720 / 1 = 720
Hence, there will be 720 cubes of side 1 unit that fill the prism if they were packed without any gaps or overlaps.

Harvey bought a. Frame in which he put his family picture in what is the area of the frame not covered by the picture
Answer:
Area of the frame not covered with photo is equal to 129 square inches
Step-by-step explanation:
Given: Image of a frame
To find: Area of the frame not covered by the picture
Solution:
Area of rectangle = length of the rectangle × breadth of rectangle
Area of the frame = length of frame × breadth of frame = 23 × 15 = 345 square inches
Area of the frame covered with photo = 18 × 12 = 216 square inches
Area of the frame not covered with photo = Area of the frame - Area of the frame covered with photo = 345 - 216 = 129 square inches

The required functions are obtained as f(x) = x/5, f(x) = ∛(2x), f(x) = x - 10 and f(x) = 2x/3 - 17 respectively.
What is the inverse of a function?The inverse of a function y = f(x) is defined as a function having range as the domain of the function f(x) and domain as the range. Mathematically it can be written as f⁻¹(y) = x which implies that f⁻¹(f(x)) = x.
The given problem can be solved as follows,
(a) f⁻¹(x) = 5x
Substitute x = f(x) to obtain,
f⁻¹(f(x)) = 5f(x)
=> x = 5f(x)
=> f(x) = x/5
(b) f⁻¹(x) = x³/2
Substitute x = f(x) to obtain,
f⁻¹(f(x)) = f(x)³/2
=> x = f(x)³/2
=> f(x) = ∛(2x)
(c) f⁻¹(x) = x + 10
Substitute x = f(x) to obtain,
f⁻¹(f(x)) = f(x) + 10
=> x = f(x) + 10
=> f(x) = x - 10
(d) f⁻¹(x) = 3( x + 17)/2
Substitute x = f(x) to obtain,
f⁻¹(f(x)) = 3( f(x) + 17)/2
=> 2x = 3( f(x) + 17)
=> 2x/3 = f(x) + 17
=> f(x) = 2x/3 - 17
Hence, the functions for the given inverse functions are f(x) = x/5, f(x) = ∛(2x), f(x) = x - 10 and f(x) = 2x/3 - 17 respectively.

The sum of two numbers is 43. One number is five less than three times the other number. What is the largest number?
Answer:
31
Step-by-step explanation:
Let the numbers be x and y.
"The sum of two numbers is 43." gives us the first equation.
x + y = 43
"One number is five less than three times the other number." gives us the second equation.
y = 3x - 5
Now we solve the system of two equations below.
x + y = 43
y = 3x - 5
Since the second equation is already solved for y, we will use the substitution method. We substitute 3x - 5 for y in the first equation.
x + y = 43
x + 3x - 5 = 43
4x - 5 = 43
4x = 48
x = 12
The first number is 12. Now we find the second number.
x + y = 43
12 + y = 43
y = 31
The larger number is 31.
Answer:
31 is greater
Step-by-step explanation:
I will solve your system by substitution.
x=3y−5;43=x+y
Step: Solve x=3y−5 for x:
Step: Substitute 3y−5for x in 43=x+y:
43=x+y
43=3y−5+y
43=4y−5 (Simplify both sides of the equation)
43+−4y=4y−5+−4y (Add -4y to both sides)
−4y+43=−5
−4y+43+−43=−5+−43 (Add -43 to both sides)
−4y=−48
(Divide both sides by -4)
y=12
Step: Substitute12foryinx=3y−5:
x=3y−5
x=(3)(12)−5
x=31(Simplify both sides of the equation)
Answer:
x=31 and y=12
31 is greater than 12

An angle is bisected, forming two new angles. If the original angle had a measure of 14 degrees, what is the measure of each new angle?
Hello I think the answer would be 7
An angle bisector, bisects an angle into two equal small angles
14 divided by 2 is 7
Hope this helps :)
The measure of each new angle will be 7°.
Since we are given the information that the original angle had a measure of 14 degrees, then when the angle is bisected, forming two new angles, we have to divide the original angle by 2. This will be:
= 14°/2
= 7°
Therefore, the measure of each new angle will be 7°.

H∈ IG
Answer:
x = 24°
Step-by-step explanation:
Lines JH and EG are the parallel lines and HF is a transverse.
∠JHF ≅ ∠HFE [Interior alternate angles]
m∠JHF = 2x
Since, m∠JHF = m∠JHG + m∠FHG
2x = m∠JHG + x
m∠JHG = 2x - x = x
Since m∠JHI + m∠JHG = 180° [Supplementary angles]
156° + m∠JHG = 180°
m∠JHG = 180 - 156
m∠JHG = 24°
x = 24°
Therefore, x = 24° will be the answer.

if a 10-pound turkey cost $20.42 how much does a 21-pound turkey cost
First divide $20.42 by 10 to find the cost of 1 pound/16 ounce turkey.
Dividing, this gives us 2.042.
Now, to find the cost of a 21-pound turkey, we multiply
the cost of 1 turkey by 21 to get 42.882.
So a 21-pound turkey is $42.882.
