Step-by-step explanation:

Rhian scored more in the Math test than in the English test because she had a higher percentage

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that: In the Maths test, Rhian scored 14 out of 17, hence:

Mark percentage = (14 / 17) * 100% = 82.35%

In the English test, Rhian scored 31 out of 39, hence:

Mark percentage = (31 / 39) * 100% = 79.49%

Rhian scored more in the Math test.

Solving Linear equation  4x-2y= -40 : x = 10 + 0.5y

What is Linear Equation?

A linear equation is a mathematical expression that may be written as x 1+ldots +a n+x n+b=0, where x 1, ldots, and x n are the variables and displaystyle b, a 1, ldots, and a n are the coefficients, which are frequently real integers.

Simplifying

4x + -2y to 40

Solving

4x + -2y = 40

fixing the 'x' variable.

x should be moved to the left of all terms, and the right of all other terms.

To each side of the equation, add "2y."

4x + -2y + 2y = 40 + 2y

combining similar terms

-2y + 2y = 0

4x + 0 = 40 + 2y

4x = 40 + 2y

Multiply each side by "4".

x = 10 + 0.5y

Simplifying

x = 10 + 0.5y

Hence, solving for x the value of x = 10 + 0.5y

Answer: B the lines are neither parallel nor perpendicular.

Step-by-step explanation:

To make this easier we can make both equations into y-intercept statements.

y = 5x - 7

-8y = -x - 6

y = 1/8x + 6/8

By looking at the slopes of both equations (5 and 1/8) we can see that they are neither the same nor opposite reciprocals.

The value of the car is decreased by 3.5%.

A figure or ratio stated as a fraction of 100 is called a percentage. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a standard measurement.

The value of the car two years ago was $24,000.

The value of the car this year is $23,160.

The decreased value of the car after two years will be:

= $24,000 - $23,160

= $840

Let y be the percentage by which the value of the car decreased,

y = 840/24000

y = 0.035

y = 3.5/100

y = 3.5%

The value of the car decreased by 3.5 percent in two years.

The equation will be 2d = 14 and the number of days d she can feed pickles from the bag is 7 days.

Pickles eat 2 cups of hungry hound dog food each day.

brittany wants to know how many days she can feed pickles from a 14-cup bag of hungry hounds.

We need to find the number of days d she can feed pickles from the bag.

Number of days = d,

So, Every day, Pickles consumes 2 cups of Hungry Hound dog chow.

Pickles then consume cups of Hungry Hound dog chow every day for a few days.

Then,

2*d = 14

Answer:

radius = 5.196 ins. to nearest thousandth.

Step-by-step explanation:

Volume of the cylinder = π (3)^2 7

= 63π in^3.

Volume of the cone = 1/3 π r^2 7   where r is the new radius of the cone

So, 63π = 7/3 π r^2

r^2 = 63 / 7/3

     = (63*3)/7

     = 27

r = 5.196 in.

The equation can be modelled by 23 = 12 + x

The given parameters are

Cost of book = $12

Total purchase = $23

The total purchase can be calculated by adding the cost of the book and the cost of the T-shirt

This is represented as

Total purchase =  Cost of book + Cost of T-Shirt

So, we have

23 = 12 + x

Where x represent the unknown information.

It is given that a = 30°. It is also shown that C is a right angle, thus c = 90°. The interior angles of a triangle always add up to 180°. So:

a + b + c = 180
30 + 90 + b = 180
b + 120 = 180
b + 120 - 120 = 180 - 120
b = 60°

A cylinder tank has a radius of 7.5 feet and an altitude of 14 feet. If a gallon of paint will cover 130 ft.² of surface how much paint is needed to put two coats of paint on the entire surface of the tank?

Remember that

The surface area of a cylinder is equal to

where

B is the area of the circular nase

P is the circumference of the circular base

h is the height of the cylinder

so

Find out B

we have

r=7.5 ft

pi=3.14

substitute

Find out the circumference

the value of h=14 ft

therefore

SA=2(176.625)+47.1(14)

SA=1,012.65 ft2

Remember that s needed to put two coats of paint

Multiply the surface area by 2

1,012.65*2=2,025.3 ft2

1 gallon -------> 130 ft2

applying proportion

1/130=x/2,025.3

solve for x

x=2,025.3/130

x=15.6 gal

therefore

The total surface area of the can is 61.23 square inches

The total surface area of can S = 2πr(r+h)

where:

h is the height

r is the radius

A cylinder's surface area is the area that its surface takes up in three dimensions. A three-dimensional structure known as a cylinder has circular bases that are parallel to one another. There are no vertices on it. Area of three-dimensional shapes often refers to surface area. Square units are used to denote the surface area. Examples include cm2, m2, and so forth.

Given

h = 5in

r = 1.5in

S = 2(3.14)(1.5)(1.5 + 5)

S = 6.28(1.5)(6.5)

S = 61.23 square inches

Hence the total surface area of the can is 61.23 square inches

ANSWER:

Using the process of induction we can prove that the sum of all angles of a polygon is  (n −2) ×180°

In geometry, a polygon is a planar shape characterized by a finite number of segmented straight lines linked to form a network of closed polygons (or polygonal circuit). A polygon is defined as either a bounded plane region or a bounding circuit.

Sum of all angles of a triangle is 180°

Sum of all angles of a quadrilateral is 360°

We know that a triangle has 3 sides.

Hence (n −2) ×180 for n=3 given 180

and (n −2) ×180 for n=4 gives 360.

So we can say that the formula holds by the properties of induction.

The portions of a polygonal circuit are known as its margins or sides. A polygon's vertices or corners are the points where two edges meet. The inside of a solid polygon is sometimes referred to as its body. An n-gon appears to be a polygon with n sides, similar to a triangle, which is a 3-gon.

Hence the formula (n −2) ×180◦ holds for induction.

The 3 numbers are 17/4, and the number is equal to or greater than 8, and 7 respectively. We can solve the equation using a linear equation in one variable.

A linear equation is one in which the variable's maximum power is consistently 1. A one-degree equation is another name for it. A linear equation with one variable has the formula Ax + B = 0, which is its standard form. x is a variable, A is a coefficient, and B is constant in this situation. A linear equation with two variables has the formula Ax + By = C as its standard form. Here, the variables are x and y, the coefficients are A and B, and the constant is C.

1) Given that

five times the difference between a number and two is seven more than that number

n = 17/4

2)Given that

twice a number decreased by four is greater than ten, what numbers satisfy this condition

Answer:

They are parallel because they both have the same gradient of 5.

Step-by-step explanation:

For lines to be parallel they need to contain the same gradient.

1. therefore we rearrange the second equation to get y the subject so it's in the format of y=mx+c

2.       2y-10x+3=0

- we +10x and -3 on both sides to get y on its own

         2y=10x-3

- we divide each side by 2 as we want y not 2y

          y=5x-[tex]\frac{3}{2}[/tex]

3. From this we can see that both the equation contains the same gradient (5)
