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
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
97.2 degrees!

At the aquarium, posters of sharks cost $2 and posters of jellyfish cost $6. Mr. Benson spent $64 to buy 12 posters. How many of each type of poster did Mr. Benson buy?
Answer:
8
Step-by-step explanation:
Step 1: Add the cost of the posters together
Shark: 1 = $2
Jellyfish: 1 = $6
2 + 6 = 8
Step 2: Divide the result by the total amount Mr. Benson spent
64 ÷ 8
[tex]= \frac{64}{8}[/tex]
[tex]= 8[/tex]
Therefore, Mr. Benson bought 8 of each type of poster.
The question is in the attachment.

Answer:
43
Step-by-step explanation:
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°
A certain television is advertised as a 54-inch TV (the diagonal length). If the width of the TV is 40 inches, how tall is the TV? Round to the nearest tenth of an inch.
Answer:
36.3
Step-by-step explanation:
I tried using the Pythagorean Theorem to measure the length (tallness) of the TV.
[tex]a^2 + b^2 = c^2[/tex]
[tex]a^2 + (40)^2 = (54)^2[/tex]
[tex]a^2 + 1600 = 2916[/tex]
[tex]a^2 = 2916-1600 = 1316[/tex]
[tex]a = \sqrt{1316}[/tex]
[tex]a = 36.27671429[/tex]
When this is rounded up to the nearest tenth, it would go up to 36.3.
So, the length (tallness) of the TV would be 36.3 inches.

Equations on both sides
3x + 5 = 2x -17
Solve it and show the work because i need to show the work
Answer:
x = -22
Step-by-step explanation:
Subtract 5 from both sides
3x + 5 (-5) = 2x - 17 (-5)
3x = 2x - 17
Subtract 2x from both sides
3x (-2x) = 2x (-2) -22
x = -22

please I've been looking for an answer to this question
Answer:
x = 9cm
using sine rule
a/sine(A) = b/sine(B)
a= x; A= 64° ( alternating angles)
b= 10 cm ; B = 90°
x/sine(64) = 10/sine(90)
x= {10 × sin(64)}/ sin 90
x = 9cm

(X+1,8)=(3,2y) please can u send the pic to me I really need it
Answer:
x = 2, y = 4
Step-by-step explanation:
Given
(x + 1, 8 ) = (3, 2y )
Equate the values in the x and y positions , that is
x + 1 = 3 ( subtract 1 from both sides )
x = 2
and
2y = 8 ( divide both sides by 2 )
y = 4
Answer:
(X+1,8)=(3,2y)
equating corresponding value we get
x+1=3
x=3-1=2
again
8=2y
y=8/2=4
x=2
y=4

front view
(1) side view
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.
3. A class rolled number cubes. Their results are shown in the table. What is the experimental probability of rolling the number 1? Round your answer to the nearest tenth.
17.2%
16.4%
15.7%
17.5%
Answer:
15.7%
Step-by-step explanation:
Experimental probability is the probability of something that is determined by doing an experiment.
To find the probability, divide the number of rolling a one and add all the occurrences of every other result.
So,
42 / (42 + 44 + 45 + 44 + 47 + 46) =
42 / 268 =
0.156716 =
15.6716
Rounded to the nearest tenth, the probability of rolling a one would be 15.7%.
