If x represents the age of the father and
y represents the present age of the son,
then the statement for 'present age of
the father is 5 more than 6 times the
age of the son' in terms of a
mathematical equation is *
Answer:
x = 5+6y
Step-by-step explanation:
Let x represents the age of the father and y represents the present age of the son.
ATQ,
The present age of the father is 5 more than 6 times the age of the son. We can write it in the form of equation as follows :
6 times the age of the son means 6y. So,
x = 5+6y
Hence, the mathematical equation is "x = 5+6y".

Answer: 6.4cm
Step-by-step explanation:
The area of a trapezoid is given as:
= 1/2(a + b)h
We then slot the given values into the formula. This will be:
1/2(15.8 + b) × 7.3 = 81.03.
7.3(15.8 + b)= 81.03 × 2
7.3(15.8 + b) = 162.06
115.34 + 7.3b = 162.06
7.3b = 162.06 - 115.34
7.3b = 46.72
b = 46.72/7.3
b = 6.4
Therefore, the answer is 6.4cm.
For which sample size (n) and sample proportion (p) can a normal curve be
used to approximate the sampling distribution?
Answer:
Option c.
Step-by-step explanation:
Using the normal curve to approximate a sampling distribution:
For a sample size n and a proportion n, the normal curve can be used if:
[tex]np \geq 10[/tex] and [tex]n(1-p) \geq 10[/tex]
Option a:
[tex]np = 35*0.8 = 28 > 10[/tex]
[tex]n(1-p) = 35*0.2 = 7 < 10[/tex]
So option a cannot be used.
Option b:
[tex]np = 65*0.9 = 58.5 > 10[/tex]
[tex]n(1-p) = 65*0.1 = 6.5 < 10[/tex]
So option b cannot be used.
Option c:
[tex]np = 65*0.8 = 52 > 10[/tex]
[tex]n(1-p) = 65*0.2 = 13 > 10[/tex]
So option c can be used, and is the answer
Option d:
[tex]np = 35*0.9 = 31.5 > 10[/tex]
[tex]n(1-p) = 35*0.1 = 3.5 < 10[/tex]
So option d cannot be used.
The answer is given by option c.

A shirt originally priced at $45 was marked down 15%. After a week, the shirt was marked down another 15% off the sale price. What is the percent of change from the original price to the final sale price? Write as decimal percent.
27.76% I believe. infinite decimal.
Answer: 27.75 decrease
Step-by-step explanation:
45 times .85 (100-15(perecent)= 85) is a
a times .85 is b
(b-45)/45 is -0.2775 which is 27.75% which is -27.75
Which system of equations does not have the

1) -12x - 9y = -30
12x + 10y = 32
2) 20x + 15y = 50
-18x -15y = -48
3) 24x + 18y = 60
-24x - 20y = -64
4) 40x + 30y = 100
36x + 30y = -96
As per linear equation, except for the option(4), all system of equations have same solution.
What is a linear equation?"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, 'A' is a coefficient and 'B' is constant".
Given system equations:
4x + 3y = 10 (equation 1)
-6x - 5y = -16
⇒ (6x + 5y) = 16 (equation 2)
Option. 1: - 12x - 9y = - 30
⇒ - 3(4x + 3y) = - 3
⇒ (4x + 3y) = 10 (equation 3)
Again, 12x + 10y = 32
⇒ 2(6x + 5y) = 16
⇒ (6x + 5y) = 16 (equation 4)
Option. 2: 20x + 15y = 50
⇒ 5(4x + 3y) = 50
⇒ (4x + 3y) = 10 (equation 5)
Again, -18x -15y = -48
⇒ - 3(6x + 5y) = - 48
⇒ (6x + 5y) = 16 (equation 6)
Option. 3: 24x + 18y = 60
⇒ 6(4x + 3y) = 60
⇒ (4x + 3y) = 10 (equation 7)
-24x - 20y = -64
⇒ - 4(6x + 5y) = - 64
⇒ (6x + 5y) = 16 (equation 8)
Option. 4: 40x + 30y = 100
⇒ 10(4x + 3y) = 100
⇒ (4x + 3y) = 10 (equation 9)
Again, 36x + 30y = -96
⇒ 6(6x + 5y) = -96
⇒ (6x + 5y) = -16 (equation 10)
Therefore, except for the option(4), all system of equations have same solution.

Find the area of this composite figure
Answer:
23.9425 (Round if needed)
Step-by-step explanation:
This is 2 half circles so you can find the area of a circle and divide it by 2.
First circle has a diameter of 6 cm
6/2=3 cm
So, circle has radius of 3.
Area of circle= 3.14(pi) radius^2
3.14 x 3^2= 28.26
28.26/2=14.13 cm
Area of first half circle= 14.13
Repeat that process for the second circle.
3.14 x 2.5^2=19.625
19.625/2=9.8125
14.13+9.8215=23.9425
Area=23.9425
