The cost of 2 rugby balls and 3 golf balls is £18.39.
The cost of 5 rugby balls and 7 golf balls is £45.10.
Work out the cost of
a) a rugby ball.
b) a golf ball.

Step-by-step explanation:

4(x - 3) + 5x - x²

If x = 2,

= 4(2 - 3) + 5(2) - (2)²

= 4(-1) + 10 - 4

= -4 + 10 - 4

= 6 - 4

= 2.

Therefore, it is confirmed that x = 2.

Answer:

50

Step-by-step explanation:

    [tex]\sf 2\sqrt{5}*5*\sqrt{5} = 2*5* \sqrt{5*5}[/tex]

                          = 10 * 5

                           = 50

Multiply the rational numbers and multiply the radicals.

The measures of the unknown angles are as follows:

The measures of each angles can be found as follows:

Therefore,

∠AEB = ∠CED (vertically opposite angle)

∠DEA = ∠BEC (vertically opposite angle)

Vertically opposite angles are equal.

Therefore,

4x = 75 - x

4x + x = 75

5x = 75

x = 75 / 5

x = 15

Therefore,

∠DEA = ∠BEC = 4(15) = 60°

∠AEB = ∠CED  = 360 - 120 / 2 = 240 / 2 = 120°

The following linear equation gives Johnny's savings w weeks after her opened the account.

S(w) = $95 + $15*w

We know that initially, Johnny deposits an amount of $95, and then he saves $15 per week.

So, after w weeks, the amount in that savings account will be:

S(w) = $95 + $15*w

A certain plant grows 1 1/6 inches each week. it will rake the plant to grow 6 1/6 inches is 5 weeks 2 days.

Time is ongoing progression of existence and things that happen in what seems to be an irrevocable order from the past, present, and forward into the future. It is a quantity that is part of several measurements that are used to compare the length of events or the gaps between them, to compare how long they last, to order events, and to measure how quickly the things change in the real world or in our conscious experience. Along with the three spatial dimensions, time is frequently referred to as a fourth dimension.

Time has long been an important subject of study in religion, philosophy, and science, but defining it in a manner applicable to all fields without the circularity has consistently eluded scholars. Nevertheless, diverse fields such as the business, industry, sports, sciences, and the performing arts all incorporate some notion of time into their respective measuring systems.

A certain plant grows every week = [tex]1\frac{1}{6}[/tex] = [tex]\frac{7}{6}[/tex] inches

1 week = 7 days

Therefore in 1 day plant grows = [tex]\frac{\frac{7}{6} }{7}[/tex]

                                                        = [tex]\frac{1}{6}[/tex] inch

Now we have to calculate the number of days in which the plant grows [tex]6\frac{1}{6}[/tex]  inches ≈ [tex]\frac{37}{6}[/tex] inch

Number of days = [tex]\frac{Total growth}{growth in one day}[/tex]

                          = [tex]\frac{37}{6}[/tex] ÷ [tex]\frac{1}{6}[/tex]

                          = [tex]\frac{37}{6}[/tex]  × 6

                          = 37 days ≈ 5 weeks and 2 days

It will take plant 5 weeks 2 days to grow [tex]6\frac{1}{6}[/tex] inches.

Answer:

20.8 cm^2.

Step-by-step explanation:

Area = 1/2 * base * height

         = 1/2 * 8 * 5.2

Answer:

A = 20.8 cm²

Step-by-step explanation:

We have just to use the following expression:

A = (Base x height) / 2

So:

A = (8 x 5.2) / 2

A = 4 x 5,2

A = 20.8 cm²

He will pay $24.055 after discount and sales tax.

A sales tax is a fee that is paid to the government when specified goods and services are sold. Typically, laws permit the vendor to charge the customer the tax at the time of purchase. Use taxes are typically used to describe taxes on goods and services that consumers pay directly to a governing authority.

Given Data

Car cost = $24.211

Discount = 8%

Car cost after discount:

= 24.211 - 8%

= 22.274

Car cost after sales tax:

= 22.274(8%)

= 22.274 (0.08)

= 1.781

Cost of car =  22.274 + 1.781

The probability that the amount dispensed per box will have to be increased is 0.0062.

Consider the provided information.

Sample of 16 boxes is selected at random.

If the mean for 1 hour is 1 pound and the standard deviation is 0.1

1 Pound = 16 ounces , then 0.1 Pound = 16/10 = 1.6 ounces

Thus: μ = 16 ounces and σ = 1.6 ounces.

Compute the test probability

z= x−μ/σ/[tex]\sqrt{n}[/tex]

z= 15-16/ 1.6/[tex]\sqrt{4}[/tex]

z= -1/ 0.4

z= -2.5

The expression of b over negative 5.6 is less than or equal to negative 4.9 for b ≤ 0.7 ( b less than or equal to 0.7 ).

Based on the given conditions,

Negative 5.6 means = -5.6

Negative 4.9 means = -4.9

Negative 5.6 means ≤ Negative 4.9 means

Then,

-5.6  ≤  -4.9

But,

Let the number b is over negative 5.6,

It means,

We can write,

b + (-5.6)      (Equation-1)

This equation-1 is write into,

b + (-5.6) ≤  -4.9

b - 5.6 ≤  -4.9

b ≤ (-4.9) + 5.6

The value of c is -3.

The factorization of the polynomial is [tex](x+3)(x^3-3x+2)[/tex].

Given that:-

Polynomial P(x) = x⁴ + 3x³ + cx² - 7x + 6 is divisible by (x + 3).

We have to determine the value of c and factorize the polynomial.

Using remainder theorem, putting x = -3 in the given polynomial, we get

[tex]P(-3)= (-3)^4+3(-3)^3+c(-3)^2-7(-3)+6=0[/tex]

P(-3) = 81 -81 +9c +21 +6 = 0

9c + 27 = 0

9c = -27

c = -27/9 = -3

Dividing the given polynomial  x⁴ + 3x³ -3x² - 7x + 6  by (x + 3), we get,

[tex]x^3-3x+2[/tex]

I guess you want to draw the graph.

The graph is a straight line

-6x - 20 = 4y

When x = 0:

-6(0) - 20 = 4y

y = -20/4 = -5

So, one point on the graph

= (0, -5)

When y = -2:

Plugging y = -2 into the equation:

-6x - 20 = 4(-2)

-6x = -8 + 20 = -12

x = -2

So, another point is (-2, -2)

Mark these 2 points on the graph paper

and draw a line passing through them.
