Answer:

128

Step-by-step explanation:

Sum of interior angles of a 4 sided quadrilateral is 360.

90 + 90 + 52 + x = 360

232 + x = 360

x = 360 - 232

x = 128

Answer:

{y = 15/8 - (9 x)/8, y = -(7 x)/8 - 2}

{9 x + 8 y = 15, 7 x + 8 (y + 2) = 0}

Answer:

Speed of boat in still water = 11 miles per hour.

Step-by-step explanation:

Speed = distance / time

or

Distance= Speed * time

Let s be speed of the boat upstream and r be the speed of the river.

Then

Upstream speed=  s- r = 60/6= 10 miles per hour

Downstream speed= s+r= 72/6= 12 miles per hour

Therefore

s-r= 10--------- equation A

s+r= 12--------- equation B

Adding equation A and Eq. b

s-r= 10--------- equation A

s+r= 12--------- equation B    

2s    = 22                            

or

s= 22/2= 11 miles per hour.

Speed of boat in still water = 11 miles per hour.

Step-by-step explanation:

I applied proportional reasoning as I worked through these problems by using this reasoning to answer all the questions.

Proportional reasoning can be applied by using formal operational reasoning. There are strategies that teachers can use to help pupils apply proportional reasoning correctly.

According to Piaget's model of mental development, "formal operational reasoning," which is learned in the later phases of intellectual development, includes arguments based upon relations of proportionality. There are strategies that teachers can use to help pupils apply proportional reasoning correctly.

Finding missing values is only one aspect of proportional reasoning; it also serves as a lens through which to solve problems and builds crucial groundwork for mathematical thinking. Proportional reasoning can be applied by using formal operational reasoning.

Correct Question:

At a bake sale, plates of cookies, p, are sold for $5 each. The amount of money from the sale of cookies is expressed as dollars, d. Which equation represents the earnings of the bake sale?

1. p = 5d  

2. d = p + 5

3. d = 5p

Answer:

3. d = 5p

Step-by-step explanation:

As one plate of cookies price is 5 $

The d is expressed as numbers of dollars which are earned.

Earnings = d = 5 x number of plates sold (p)

therefore

d = 5p

Answer:

x^2+y^2 = 49

Step-by-step explanation:

This is a circle.

The generic equation of a circle is

(x-h)^2+ (y-k)^2 = r^2

where (h,k) is the center and r is the radius

The center of the circle is at the origin which is (0,0)

The radius is 7

(x-0)^2+(y-0)^2 = 7^2

x^2+y^2 = 49

Answer:

[tex] \displaystyle {x}^{2} + {y}^{2} = 49[/tex]

Step-by-step explanation:

we are given a circle

we want to figure out the equation of the circle

remember that,

[tex] \rm \displaystyle E _{c} : (x - {h)}^{2} + (y - k {)}^{2} = {r}^{2} [/tex]

(h,k) are the centre of the circle

we can clearly see that the centre of the circle is (0,0) and the redious is 7 units

thus substitute:

[tex] \displaystyle (x - {0)}^{2} + (y - 0{)}^{2} = {7}^{2} [/tex]

further simplification is needed:

[tex] \displaystyle {x}^{2} + {y}^{2} = 49[/tex]

and we are done!

Answer:

25

Step-by-step explanation:

To get this right, we need to get the correct formula for the volume of a cube.

Imagine this:

What is the area of a square? Easy ! Length of the edge times itself. You can imagine what this means as the edge if the we have one line E move straight along an E-long line, the path it made is the square.

Similarly to the cube. Imagine what can be a volume of a cube with edge E that has something to do with the edge?

That's right. A square with edge Emove vertically straight in a E-long line. So the correct volume should be the area of the square times the length of its edge. But the area of the square is already the edge times itself

In formula, if a cube has volume V and edge length E, we have the equation.

V = E×E×E

Answer:

$50 - $9.99 = $40.01

$40.01 ÷ $3.99 = 10

so the answer is 10

Step-by-step explanation:

if thats not whats being asked sorry

Inequality shows a relationship between two numbers or two expressions.

The inequality describes the number of movies Parv can buy.

9.99 + 3.99x ≤ 50

Where x is the number of movies.

The number of movies Parv can buy is 10.

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal= ≥

We have,

Gift card = $50

Cost of a pack of games = $9.99

Cost of each movie = $3.99

x = number of movies

The inequality describes the number of movies Parv can buy.

9.99 + 3.99x ≤ 50

Where x is the number of movies.

Solve for x.

9.99 + 3.99x ≤ 50

Subtract 9.99 on both sides.

3.99x ≤ 50 - 9.99

3.99x ≤ 40.01

Divide both sides by 3.99

x ≤ 40.01/3.99

x ≤ 10

This means the number of movies Parv can buy is 10.

We can cross-check.

9.99 + 3.99 x 10 ≤ 50

9.99 + 39.9 ≤ 50

49.89 ≤ 50

Thus,

The number of movies Parv can buy is 10.

4 appears the most so that's the mode.

Mean = (Sum of numbers)/(3 numbers)

Mean = (4 + 4 + 10)/3

Mean = (18)/3

Mean = 6

The three numbers that have a mode of 4 and a mean of 6​ are 4, 4, and 10.

Mean is defined as the ratio of the sum of the number of the data sets to the total number of the data. A set of data values mode is the value that appears the most frequently.

The three numbers that have a mode of 4 and a mean of 6 will be calculated below:-

Let us suppose the three numbers are 4, 4, and 10 the mean will be calculated as:-

Mean = (Sum of numbers)/(3 numbers)

Mean = (4 + 4 + 10)/3Mean = (18)/3

Mean = 6

Answer:

Step-by-step explanation:

The accumulated value for simple interest is defined by the following formula:

FV=PV(1+it)

we have (where x is the present value or PV)

1200= x(1+.05*3)

Solve for x

1200=1.15x

x=1043.478261

We now need to use the equation for annually compounding interest

[tex]FV=PV(1+i)^t[/tex]

We have

She makes 6 equal monthly payments. Then the monthly payment will be £666.67.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The cost of a holiday is £2400. Rana pays a deposit followed by monthly payments, in the ratio deposit: a total of the monthly payments = 3:5.

Then the total of the monthly payment will be given as,

£2400 / Total of the monthly payments = 3:5

Total of the monthly payments = (5/3) x £2400

Total of the monthly payments = £4,000

She makes 6 equal monthly payments. Then the monthly payment will be given as,

Monthly payment = £4,000 / 6

Monthly payment = £666.67
