Answer:
85 units²
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
The hypotenuse is the side opposite the right angle ( third side ) , then
area = 35 + 50 = 85 units²

Find the first, fourth, and tenth terms of the arithmetic sequence described by the given rule.
A(n)=6+(n-1)(1/5)
Answers
Answer: a’(n)=1/5
Step-by-step explanation:
The first term is 6, the fourth term is 6.6, and the tenth term is 7.8 in the arithmetic sequence.
What is an arithmetic sequence?An arithmetic sequence is defined as an arrangement of numbers that is in a particular order.
The given rule for the arithmetic sequence is:
A(n) = 6 + (n - 1)(1/5)
To find the first term, substitute n = 1 in the formula:
A(1) = 6 + (1 - 1)(1/5)
A(1) = 6 + 0
A(1) = 6
Therefore, the first term of the arithmetic sequence is 6.
To find the fourth term, substitute n = 4 in the formula:
A(4) = 6 + (4 - 1)(1/5)
A(4) = 6 + 3/5
A(4) = 6.6
Therefore, the fourth term of the arithmetic sequence is 6.6.
To find the tenth term, substitute n = 10 in the formula:
A(10) = 6 + (10 - 1)(1/5)
A(10) = 6 + 9/5
A(10) = 7.8
Therefore, the tenth term of the arithmetic sequence is 7.8.

Answer:
32.0087878558 units
Step-by-step explanation:
Let the Triangle be ABC
By Pythagoras Theorem:
(BC)² = (AB)² + (AC)²
(BC)² = 13² + 29.25²
(BC)² = 169 + 855.5625
(BC)² = 1024.5625
BC = √1024.5625
BC = 32.0087878558
Therefore, x = 32.0087878558

Two trains start from Fort Worth traveling at the same speed. The trip for Train W takes 20 hours, while the trip for Train Z takes 25 hours. If the city Train Z is traveling to is 400 miles farther away than the city Train W is traveling to, how far will Train Z travel in total to reach its destination?
Answers
Answer:
= x/20=x+400/25
Distance traveled by Train W = 1600 miles
Distance traveled by Train Z = 2,000 miles
Step-by-step explanation:
Time taken for Train W to complete a trip = 20 hours
Time taken for Train Z to complete a trip = 25 hours
The city Train Z is traveling to is 400 miles farther away than the city Train W is traveling to.
both trains have same speeds and start from same location.
To find the distance in total each train travels.
Solution:
Let length of the trip of Train W be = xx miles
Speed of Train W can be given as :
⇒ \frac{Distance}{Time}
Time
Distance
⇒ \frac{x}{20}\ miles/h
20
x
miles/h
So, the length of the trip of Train Z will be = (x+400)(x+400) miles
Speed of Train Z can be given as :
⇒ \frac{Distance}{Time}
Time
Distance
⇒ \frac{x+400}{25}\ miles/h
25
x+400
miles/h
Since the speeds are same, so the equation to find xx can be given as:
⇒ \frac{x}{20}=\frac{x+400}{25}
20
x
=
25
x+400
Solving for xx
Multiplying both sides by 100 to remove fractions.
⇒ 100\times \frac{x}{20}=100\times \frac{x+400}{25}100×
20
x
=100×
25
x+400
⇒ 5x=4(x+400)5x=4(x+400)
Using distribution.
⇒ 5x=4x+16005x=4x+1600
Subtracting both sides by 4x4x
⇒ 5x-4x=4x-4x+16005x−4x=4x−4x+1600
⇒ x=1600x=1600
Thus, Distance traveled by Train W = 1600 miles
Distance traveled by Train Z = 1600+4001600+400 = 2,000 miles

What is the area of the square?
What’s the area of the circle
Answers
Answer:
Square: 144 m²
Circle: 113.04 m²
Step-by-step explanation:
The formula for area of a square: side × side.
The formula for area of a circle: r²π (radius × radius × pi)
**SQUARES HAVE EQUAL SIDES**
As shown in the photo, the side lengths of the square are 12.
side × side
12 × 12 = 144
Therefore, 144 m² is the area of the square.
-------------------------------------------------------------------------------------------------------------
The diameter of the circle is 12 as well.
But, to find the area of the circle, we need the radius.
To find the radius of a circle, divide the diameter by 2.
12 ÷ 2 = 6.
6 is the radius.
Now we plug the numbers into the equation.
**3.14 IS A SUBSTITUTE FOR PI**
r²π (radius × radius × pi)
6²π (6 × 6 × 3.14) = 113.04
Therefore, 113.04 m² is the area of the circle.

What is the diameter of a cone with height 8 m and volume 150 pi m3 ?
A. 7.5 m
B. 5V3 m
o C. 7.573 m
D. 15 m
Answers
Answer:
V = pi*r^2*h
V = 150 m^3
h = 8 m
150 = pi*r^2*8
Solve for r (the radius) then multiply by 2 to obtain the diameter.Only, this is a cone, not a cylinder.
V = 1/3 pi r^2 h
Diameter of the cone is 15 m. So, option D is correct.
What is meant by solid shape ?Solid shapes are defined as the three-dimensional objects that are described by the three dimensions length, breadth and height.
Here,
Volume of the cone is given by,
V = 150[tex]\pi[/tex] m³
Height of the cone, h = 8 m
We know, the equation for the volume of a cone is,
V = 1/3[tex]\pi[/tex]r²h
where r is the radius and h is the height of the cone.
So,
(1/3) [tex]\pi[/tex]r²h = 150[tex]\pi[/tex]
r²x 8 = 3 x 150 = 450
r² = 450/8
r² = 56.25
r = 7.5 m
Therefore, diameter of the cone,
d = 2r
d = 2 x 7.5
d = 15 m
Hence,
Diameter of the cone is 15 m.

Find the errors in her solution. What should her answer have been?
Lin's solution:
8( x - 3 ) + 7 = 2x( 4 - 17 )
8( x - 3 ) + 7 = 2x(13 )
8x - 24 + 7 = 26x
8x - 17 = 26x
-17 = 34x
-½ = x
Answers
8( x - 3 ) + 7 = 2x( 4 - 17 )
Let’s condense as she did
8( x - 3 ) + 7 = 2x ( -13 )
Distribute
8x - 24 + 7 = -26x
Combine like terms
8x - 17 = -26x
Move x to one side
-17 = -34x
Divide by -34
1/2 = x
