A man is five times as old as his son. Four years ago the man was thirteen times as old as his son.
Find their present ages.
Answer:
Age of son = 6 years
Age of man = 5×6 = 30 years
Step-by-step explanation:
GIVEN :-
A man is 5 times as old as his son. (In Present)4 years ago , the man was 13 times as old as his sonTO FIND :-
The present ages of the man & his son.SOLUTION :-
Let the present age of son be 'x'.
⇒ Present age of man = 5x
4 years ago ,
Age of son = (Present age of son) - 4 = x - 4
Age of man = (Present age of man) - 4 = 5x - 4
The man was thirteen times as old as his son. So,
[tex]=> 5x - 4 = 13(x - 4)[/tex]
Now , solve the equation.
Open the brackets in R.H.S.[tex]=> 5x - 4 = 13x - 52[/tex]
Take 5x to R.H.S. and -52 to L.H.S. Also , take care of their signs because they are getting displaced from L.H.S. to R.H.S. or vice-versa.[tex]=> 13x - 5x = 52 - 4[/tex]
[tex]=> 8x = 48[/tex]
Divide both the sides by 8[tex]=> \frac{8x}{8} = \frac{48}{8}[/tex]
[tex]=> x = 6[/tex]
CONCLUSION :-
Age of son = 6 years
Age of man = 5×6 = 30 years

The ratio of health club members who use trainers to those who do not
is 2:5. There are 342 members who use trainers. How many members
does the club have?
Answer:
Step-by-step explanation:
The anwser is 479 - 2:5 as a decimal is .4 , 342 x .4 is 126.8
342+126.8 = 178.8
round it and get 479
By using given ratio, Members does the club have are 1197.
What is ratio?"A ratio can be defined as the relationship or comparison between two numbers of the same unit to check how bigger is one number than the other one."
We have,
Ratio of health club members who use trainers and who do not is 2:5.
Members who use trainers = 342
Members who does not use trainers
= [tex]\frac{342}{2}[/tex]×[tex]5[/tex]
= 171 × 5
= 855
Total members
= 855 + 342
= 1197
Hence, Members does the club have are 1197.

James and Padma are on opposite sides of a 100-ft-wide canyon. James sees a bear at an angle of depression of 45 degrees. Padma sees the same bear at an angle of depression of 65 degrees.
What is the approximate distance, in feet, between Padma and the bear?
A
21.2ft
B
75.2ft
C
96.4ft
D
171.6ft
The approximate distance, in feet, between Padma and the bear will be 75.2 feet. Then the correct option is B.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
James and Padma are on inverse sides of a 100-broad gulch. James sees a bear at a point of discouragement of 45 degrees. Padma sees a similar bear at a point of discouragement of 65 degrees.
Let 'x' be the horizontal distance from bear to Padma. Then the equation is given as,
(tan 45°) (100 - x) = (tan 65°) x
100 - x = 2.1445x
100 = 3.1445x
x = 31.80 feet
Then the approximate distance, in feet, between Padma and the bear will be given as,
cos 65° = 31.80 / d
d = 75.2487
d ≈ 75.2 feet
The approximate distance will be 75.2 feet. Then the correct option is B.

b) How many hamburgers must Sven sell to earn $120 in a 6.5 hour
shift? (round to the nearest burger)
Answer:
Part A: $55.50
Part B: 52 hamburgers(sorry if I am wrong for part b but I think it is right)
Step-by-step explanation:
Part A: $14.50 x 3= $43.50 + 24 x $0.50= $12=
($ earned per hrs x hrs worked)+ ($ per hamburger sold x times amount)
Hence $43.50 + $12= $55.50.
Part B: $14.50 x 6.5 = $94.25 $120 - $94.25= $25.75
($ earned per hrs x hrs worked x x hrs worked) ($ earned - $ earn from shif
$25.75/0.50=51.5 (51.5 rounded to nearest burgers is 52 burgers)

Answer:
m∠N = 32°
NQ = 106°
When finding inscribed angles like ∠N with the intercepted arc, the equation is ∠N=1/2MP. (Inscribed angles are always half the degree of the arc length.) Plug in the corresponding value to get ∠N=1/2(64) to get 32°. When finding the angle of the intercepted arc with inscribed angles like NQ, the equation is NQ=2(∠P). Plug in the corresponding value to get 2(53) to get 106°.

Several cheeses are for sale. The cheese comes in wedges shaped like sectors of a circle. All of the wedges are the same height. Tyler bought a wedge. He measured the arc length of the wedge to be 12 cm and the radius to be 8 cm. Priya bought a wedge that came from a circular cheese block with radius 9 cm. The block was cut into 6 congruent sectors. Whose wedge is larger? Explain or show your reasoning.
Tyler's wedge is larger
The arc length of Priya's wedge is only 9.42, and Tyler's is 12
Tayler's wedge is larger.
What is arc length?"Arc length is the distance along the part of the circumference of any circle."
Formula to calculate the circumference of a circle:S = 2 × π × r
where, r is the radius of the radius of a circle
In this question,
Tyler bought a wedge shaped cheese with arc length 12 cm and radius 8 cm.
Priya bought a wedge that came from a circular cheese block with radius 9 cm and the block was cut into 6 congruent sectors.
The circumference of circular cheese block with radius 9 cm would be,
⇒ s = 2 × π × 9
⇒ s = 18π cm
Since, the block was cut into 6 congruent sectors.
The arc length of each block would be, 18π / 6 = 3π cm
That is, 9.43 cm
Since 12 > 9.43, Tayler's wedge is larger.

Inscribed Angle = 1/2 Intercepted Arc
< MQP = 1/2 ( 86)
< MQP = 43
Answer:
43°
Step-by-step explanation:
The measure of an inscribed angle is half the measure of the arc it subtends.
m<Q = (1/2)m(arc)MP
m<Q = 1/2 * 86°
m<Q = 43°

How many unit cubes are used to build the solid?
unit cubes are used to build the solid.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the views are not shown.
So, I will answer this question with the attached views of a rectangular prism.
Required
The number of cubes used
For the attached views of the rectangular prism, we will make use of the following representations
Top view [tex]\to[/tex] Width
Front view [tex]\to[/tex] Height
Side view [tex]\to[/tex] Length
So, we have:
[tex]Width = 2 units[/tex]
[tex]Height = 6 units[/tex]
[tex]Length = 1\ unit[/tex]
The number of cubes is calculated by solving for the volume of the prism.
For a rectangular prism, the volume is:
[tex]Volume = Length * Width * Height[/tex]
[tex]Volume = 2 * 6 * 1[/tex]
[tex]Volume = 12[/tex]
This implies that 12 cubes were used to build the solid.
In ΔCDE, the measure of ∠E=90°, DE = 39 feet, and CD = 89 feet. Find the measure of ∠C to the nearest degree.
Firstly this shape is an triangle and a triangle has 3 sides/ angles and all angles sum up to 180 degrees...
E = 90 degrees
This explains that it is an hypotenuse triangle so...
answer:
= 39x39 = 1521
= 89x89 = 7921
= 1521 + 7921 = 9442
= square root of 9442 = 97.169954204 rounded off to 97.2
