Brian is mowing his lawn. He and his family have 7.84 acres. Brian mows 1.29 1 acres on Monday, 0.85 acres on Tuesday, and 3.63 acres on Thursday. How many acres does Brian have left to mow? * 0 2.70 0 20.7 02.07 O 0.207

**Answer:**

2.07

**Step-by-step explanation:**

I DID IT ON A CALCULATOR

The **area **of a 2D form is the amount of **space **within its **perimeter**. The **area **that is needed to be **mowed **by Brian is **2.07 acres.**

The **area **of a 2D form is the amount of **space **within its **perimeter**. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or other **quadrilateral**, multiply its length by its width.

The **total **area that is needed to mow is 7.84 acres. Given that **Brian **mows 1.291 acres on **Monday**, 0.85 acres on **Tuesday**, and 3.63 **acres **on Thursday. Therefore, the area **already **mowed by **Brian **can be written as,

[tex]\rm \text{The area already mowed by Brian} = 1.291 + 0.85 + 3.63= 5.771\ acres[/tex]

The **area **that is left to mow = Total **area **- **Area already **mowed by Brian

= 7.84 - 5.771

= 2.069 **acres ≈ 2.07 acres**

Hence, the **area **that is needed to be **mowed **by Brian is **2.07 acres.**

a cyclist covers a distance of 15km in 2hours calculate his speed

Answer:

Step-by-step explanation:

Given data

Distance= 15km

Time = 2 hours

We know that the expression for the speed is

Speed= distance/time

Substitute

Speed= 15/2

Speed= 7.5 km per hour

Hence the speed is 7.5km/h

What is the highest common factor of 36 and 56???

**Answer:**

4

**Step-by-step explanation:**

Greatest common factor (GCF) of 36 and 56 is 4.

Step-1: Prime Factorization of 36

Prime factors of 36 are 2, 3. Prime factorization of 36 in exponential form is:

36 = 2^2 × 3^2

Step-2: Prime Factorization of 56

Prime factors of 56 are 2, 7. Prime factorization of 56 in exponential form is:

56 = 2^3 × 7^1

Step-3: Factors of 36

List of positive integer factors of 36 that divides 36 without a remainder.

1, 2, 3, 4, 6, 9, 12, 18

Step-4: Factors of 56

List of positive integer factors of 56 that divides 36 without a remainder.

1, 2, 4, 7, 8, 14, 28

Final Step: Biggest Common Factor Number

We found the factors and prime factorization of 36 and 56. The biggest common factor number is the GCF number.

So the greatest common factor 36 and 56 is 4.

The **highest** common **factor **of 36 and 56 is 4 after using division algorithm, the answer is 4.

It is defined as the **common** number of two **integers**, which is the **lowest** number that is a **multiple **of two or more numbers. The full name of LCM is the **least** common **multiple**.

It is given that:

The two numbers are: 36 and 56

As we know GCF means highest **common **factor, the factor which presents the in both **numbers**:

The GCF(36, 56) can be found using the Division Lemma:

56 = 36x1 + 20

36 = 20x1 + 16

20 = 16x1 + 4

16 = 4x4 + 0

The value of GCF(36, 56) :

GCF(36, 56) = 4

Thus, the **highest** common **factor **of 36 and 56 is 4 after using division algorithm, the answer is 4.

Use the distance formula to calculate the distance between the following two points:

(-1,1) and (4, 11)

The distance between the two points is approximately

units.

**Answer:**

d = 11 units if rounded to nearest whole number

**Step-by-step explanation:**

Distance formula:

d=√((x_2-x_1)²+(y_2-y_1)²)

Your ordered pairs (-1, 1) and (4, 11)

d=√((4-(-1))²+(11-1)²)

d=√((4+1))²+(10))²)

d=√((5)²+ 100)

d = √125

d = 11.18

d = 11 units if rounded to nearest whole number

Which graph represents the equation x=2?

**Answer:**

1)

**Step-by-step explanation:**

In the line that is the graph of equation x = 2, every ordered pair has 2 as its x-coordinate. That means it's a vertical line that passes through x = 2 on the x-axis.

Answer: 1)

The **graph **option 1) is the correct answer.

An **equation **is a mathematical statement that shows that two mathematical **expressions **are equal.

Given is an **equation**, x = 2

We see x **intercept **is 2 and there is no **y intercept**,

We know when x = a then the line is always **parallel **to **y-axis **and here x intercept is 2 therefore the **line **will pass through 2 on **x-axis**.

In graph 1) The line is passing through 2 on **x-axis** and is **parallel **to **y-axis**.

Hence, The **graph **option 1) is the correct answer.

Two vectors with magnitudes of 6 and 9 have a dot product equal to –27. Find the angle between the vectors.

**Answer:**

120°

**Step-by-step explanation:**

From the question,

The expression for the dot product of two vector is given as

a.b = abcosθ................... Equation 1

make θ the subject of the equation

θ =cos⁻¹ (a.b/ab)......................... Equation 2

Where θ = angle between the vector.

Given: a.b = -27, a = 6, b = 9

Substitute these values into equation 2

θ = cos⁻¹[-27/(6×9)]

θ = cos⁻¹(-27/54)

θ = cos⁻¹(-0.5)

θ = 120°.

Hence the angle between the vector is 120°

A slide at a children's park is 74 inches tall in the horizontal distance The slide covers is 70 inches what is the angle measures created by the slide and the ground

Answer:

46.6°

Step-by-step explanation:

We solve the above question using Trigonometric function of Cosine.

tan x = Opposite/Adjacent

x = The angle

Hypotenuse = Slide covers = 70 inches

Adjacent = 74 inches

tan x = 74/70

x = arc tan (74/70)

x = 46.591140271°

Approximately = 46.6°

It costs $5.44 for a pack of 16 pens. Find the unit price in dollars per pen. Round your answer to the nearest cent

**Explanation:**

**to find unit rate, set up the problem like a fraction. put the total cost on top, and the number of pens in a pack on bottom. Divided by the number of pens in the pack, which is 16. The answer will be the unit rate. **

**FOR EXAMPLE:**

Alice purchased a compass from an online retailer. The cost of the compass was $60.00, and was marked 40% off. Sales tax for the item is 7.5%, plus a shipping fee of $5.99. What is the final price, including discount, tax and shipping?

**Answer:**

$60.00 * 1.075 * .6 + 5.99 = $44.69

when you have multiple fees and discounts and taxes and whatever else, you should follow the order of all operations. multiplication and division before addition and subtraction, and so on.

**Step-by-step explanation:**

For discount and sales tax you multiply, and for shipping you just add the fee. We will save shipping for last since it doesn't effect the discount or tax. Meanwhile you could apply the discount and tax in any order.

To apply a discount you take the price and multiply by 1 minus the percent in decimal form. decimal form of a percent is basically the number divided by 100. so 40% = .4 then 1 - .4 = .6

to apply a ttax you multiply 1 plus the percent in decimal form. tax is 7.5% so in decimal form that's .075 then 1 plus the tax is 1.075

so now you multiply 60 * .6 * 1.075 and also remember 60 * .6 * 1.075 = 60 * 1.075 * .6 but the answer is $38.70

Now add the shipping, so 38.70 + 5..99 = $44.69
