7a* Consider the distance is x

2/3x = 240

x = 360

The Distance between two points = 360 Km

7b* Consider the average speed at 2/3 distance was V

(45+V)/2 = 54

45+V = 108

V= 108-45= 63km/hr

The average speed for the last 2/3 trip was 63 km/hr

Answer:

24.2

Step-by-step explanation:

The perimeter is the sum of the sides:

10.5 + 7.4 + 6.3 = 24.2

Answer:

6 x 4 = 24, 24 x 2 = 48

7 x 6 = 42

7 x 4 = 28, 28 x 2 = 56

6 x 4 x 1/2(basically just dividing by 2) = 12, 12 x 2(two triangles) = 24

5 x 5 = 25, 25 x 2 = 50

Add given areas:

48 + 42 + 56 + 24 + 50 = 220 ft^2 is your answer.

Answer:

3000 ft^2

Step-by-step explanation:

The top of the play ground

24 cm * 5ft/ 2cm = 60 ft

The side of the play ground

20 cm * 5ft /2cm = 50 ft

The area is

A = l * w = 60 ft * 50 ft = 3000 ft^2

The value of y in the given similar triangles is 20.

Two triangles are said to be similar if their corresponding angles are congruent to each other and the corresponding sides are in equal ratios.

Given are two triangles, we need to find the value of y so that the triangles be similar by SSS rule,

If the figures are similar by SSS Similarity Theorem, then the ratio of its corresponding sides must be proportional,

So,

14/28 = 10/y

y = 20

Hence, the value of y in the given similar triangles is 20.

Answer:

20,000 per sq. km.

Step-by-step explanation:

In this question, the variable k represents the total number of people in a single square km. Since we are provided both the total number of the population and the total square kilometers of the land, we can calculate the value of k by dividing the population size by the total land. Therefore, the calculation would be the following...

[tex]\frac{10,400,000 people}{520km^{2} }[/tex] = k

20,000 per sq. km. = k

Finally, we can see that the value of k is 20,000 per sq. km.

Answer:

A linear function is written in slope-intercept form as:

y = a*x + b

Where a is the slope and b is the y-intercept.

So any function of this shape, is a linear function, such that when graphed it is a straight line.

In this case, the function you wrote is:

Q: y = 1/3x + 2

Now, if the function is exactly what you wrote, then x is in the denominator:

y = 1/(3*x) + 2

Clearly, this is different than the general linear equation you can see above (here the variable is in the denominator) then in this case Q is non-linear.

If instead, the actual function Q is:

Q: y = (1/3)*x + 2

Then this is a linear equation, where the slope is 1/3 and the y-intercept is 2.

The factor form of expression (b³ - 1,000) will be;

⇒ (b - 10) (b² + 10b + 100)

What is mean by Factor?

A number or an algebraic expression that divides the another number or algebraic expression is called the factor of same number.

Given that;

The algebraic expression is;

⇒ b³ - 1,000

Now, Solve the expression for the factor form as;

Since, The formula is;

a³ - b³ = (a - b) (a² + ab + b²)

Hence, we factor the expression  b³ - 1,000 with the help of above formula as;

⇒ b³ - 1,000

⇒ b³ - 10³

⇒ (b - 10) (b² + b × 10 + 10²)

⇒ (b - 10) (b² + 10b + 100)

Thus,  b³ - 1,000 =  (b - 10) (b² + 10b + 100)

Therefore,

The factor form of expression (b³ - 1,000) will be;

⇒ (b - 10) (b² + 10b + 100)

Answer:

x=-2, -4

Step-by-step explanation:

1(x+3)^2-1=0

Add 1 to each side

1(x+3)^2-1+1=0+1

(x+3)^2=1

Take the square root of each side

sqrt((x+3)^2)=sqrt(1)

x+3 = ±1

x+3 = 1    x+3 = -1

Subtract 3 from each side

x+3-3 = 1-3    x+3-3 = -1-3

x = -2     x=-4

Now,

Use the algebraic identity ⇻ (a - b)² = a² - 2ab + b²

[tex](3x - 2y) {}^{2} = (5) {}^{2} \\ 3x {}^{2} - 2 \times 3x \times 2y + 2y {}^{2} = 5 {}^{2} \\ 9 {x}^{2} - 12xy + 4y {}^{2} = 25 \\9x {}^{2} + 4y {}^{2} = 25 + 12xy \\ 9x {}^{2} + 4 {y}^{2} - 1 = 24 + 12xy[/tex]

✐ So, the value of 9x² + 4y² - 1 is 24 + 12xy

Answer:

A = true

B = false

C = false

D = True

Step-by-step explanation:

Cartons of blackberries = 25

Jars of blackberry jam made = 9

Cartons of blackberries left = 10

Cartons of blackberry used = Cartons of blackberries - Cartons of blackberries left

= 25 - 10

= 15

Cartons of blackberry used = 15

Cartons of blackberry used per jam = Cartons of blackberry used / Jars of blackberry jam made

= 15/9

= 5/3

A = true

15 jars of blackberry = Cartons of blackberry used per jam × jars of black berry made

= 5/3 × 15

= 75/3

= 25 cartons of blackberry

B = false

She can make 15 jars of blackberry jam using 25 cartons of blackberry

C = false

Cartons of blackberries left = 10

Number of blackberry jam made with 10 cartons of blackberry = Cartons of blackberries left / Cartons of blackberry used per jam

= 10 ÷ 5/3

= 10 × 3/5

= 30/5

= 6

Problem 3

-------------------------

Explanation:

Two points from the graph are (10,2) and (20,4)

Apply the slope formula

m = (y2-y1)/(x2-x1)

m = (4-2)/(20-10)

m = 2/10

m = 1/5

The slope of the graph is 1/5.

Do the same for two points from the table. I'll use the first two rows

m = (y2-y1)/(x2-x1)

m = (4-2)/(10-5)

m = 2/5

The slope of the table is 2/5.

Subtract the two slopes to wrap things up:

2/5 - 1/5 = (2-1)/5 = 1/5
