Answer:

z = 13.75 * 0.8 = 11 ( two nonzero digits )  

Step-by-step explanation:

An equation that has two decimal places multiplied by a number with one decimal place can be written as

z = x*y

where x can be = 13.75

and y = 0.8

therefore : z = 13.75 * 0.8 = 11 ( two nonzero digits )

Answer:  x = 2/5 in fraction form

In decimal form, the answer is x = 0.4

====================================================

Work Shown:

2/3 = two thirds

2/3 + (1/3)x = 2x  is the equation you're given

Multiply every term by 3 so that we clear out the fractions

3*(2/3) + 3*(1/3)x = 3*2x

2 + x = 6x

From here, we solve for x

2 + x = 6x

2+x-x = 6x-x .... subtract x from both sides

2 = 5x

5x = 2

5x/5 = 2/5 ... divide both sides by 5

x = 2/5

x = 0.4

The solution of the expression is,

⇒ x = 0.4

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

''Two thirds plus one third times x equals two times x.''

Now, We can simplify as;

⇒ 2/3 + 1/3x = 2x

Solve for x as;

⇒ 2/3 = 2x - 1/3x

⇒ 2/3 = 5x/3

⇒ 2 = 5x

⇒ x = 2/5

⇒ x = 0.4

Thus, The solution of the expression is,

⇒ x = 0.4

Answer:

i. The relative error in the estimated distance is approximately 7.5%.

ii. The value of the estimated distance was about 12.5 miles far of from the actual value.

Step-by-step explanation:

Given that;

Estimated distance  ≅ 180 miles

Actual distance = 167.5 miles

Then,

Estimated distance - Actual distance = 180 - 167.5

                                                             = 12.5 miles

So that,

Relative error = [tex](\frac{estimated distance - actual distance}{actual distance} )[/tex] × 100%

                       = [tex]\frac{12.5}{167.5}[/tex] × 100%

                       = 0.07463 × 100%

                       = 7.5%

i. The relative error in the estimated distance is approximately 7.5%.

ii. The value of the estimated distance was about 12.5 miles far of from the actual value.

Answer:

x = 23

Step-by-step explanation:

Step 1: Write out equation

(58 - x) - (x) = 12

Step 2: Distribute negative

58 - x - x = 12

Step 3: Combine like terms

58 - 2x = 12

Step 4: Subtract 58 on both sides

-2x = -46

Step 5: Isolate x (divide both sides by -2)

x = 23

Answer:

36cm²

Step-by-step explanation:

From the sketched diagram of the Quadrilateral above, we have two triangles that are joined together, ∆PQR and ∆PSR

Both triangles are right angled triangles.

Step 1

We solve for ∆PQR

When solving for the sides of a right angled triangle, if two sides are given, we solve for the third sides using Pythagoras Theorem

Pythagoras Theorem =

c² = a² + b²

Where c = Longest side

For ∆PQR,

/PQ/ = 3 cm = a

/QR/ = 4 cm = b

/PR/ = c ??

c² = 3² + 4²

c² = 9 + 16

c² = 25

c = √25

c = 5cm

/PS/ = 5cm

We find the Area of this triangle using Heron's formula

= √s(s - a)(s - b)(s - c)

Where s = a + b + c/2

s = 3 + 4 + 5/2

= 12/2

s = 6

Area of the ∆PQR = √6(6 - 3)(6 - 4)(6 - 5)

= √6 × 3 × 2 × 1

= √36

= 6cm²

Area of the ∆PQR

Step 2

We solve for ∆PSR. Just like in Step 1, we solve for third side not given using Pythagoras Theorem

/PS/ = 13cm = c

/PR/ = 5cm = a

/SR/ = ?? = b

c² = a² + b²

13² = 5² + b²

b² = 13² - 5²

b² = 169 - 25

b² = 144

b = √144

b = 12cm

/SR/ = 12cm

We find the Area of this triangle using Heron's formula

= √s(s - a)(s - b)(s - c)

Where s = a + b + c/2

s = 5 + 12 + 13/2

= 30/2

s = 15

Area of the ∆PSR = √15(15 - 5)(15 - 12)(15 - 13)

= √15 × 10 × 3 × 2

= √900

= 30cm²

Area of the ∆PSR = 30 cm²

Step 3

We find the Area of the Quadrilateral

Area of the Quadrilateral (PQRS)= Area of ∆PQR + Area of ∆PSR

= 6cm² + 30cm²

= 36cm²

Therefore the Area of the Quadrilateral PQRS = 36cm²

4. Midpoint (M) of AB, for A(-2, -3) and B(1, 2) is given as:

[tex] M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}) [/tex]

Let [tex] A(-2, -3) = (x_1, y_1) [/tex]

[tex] B(1, 2) = (x_2, y_2) [/tex]

Thus:

[tex] M(\frac{-2 + 1}{2}, \frac{-3 + 2}{2}) [/tex]

[tex] M(\frac{-1}{2}, \frac{-1}{2}) [/tex]

5. Given M(3, 5) as midpoint of CD, and C(-1, -1),

let [tex] C(-1, -1) = (x_2, y_2) [/tex]

[tex] D(?, ?) = (x_1, y_1) [/tex]

[tex] M(3, 5) = (\frac{x_1 +(-1)}{2}, \frac{y_1 +(-1)}{2}) [/tex]

Rewrite the equation to find the coordinates of D

[tex] 3 = \frac{x_1 - 1}{2} [/tex] and [tex] 5 = \frac{y_1 - 1}{2} [/tex]

Solve for each:

[tex] 3 = \frac{x_1 - 1}{2} [/tex]

[tex] 3*2 = \frac{x_1 - 1}{2}*2 [/tex]

[tex] 6 = x_1 - 1 [/tex]

[tex] 6 + 1= x_1 - 1 + 1 [/tex]

[tex] 7 = x_1 [/tex]

[tex] x_1 = 7 [/tex]

[tex] 5 = \frac{y_1 - 1}{2} [/tex]

[tex] 5*2 = \frac{y_1 - 1}{2}*2 [/tex]

[tex] 10 = y_1 - 1 [/tex]

[tex] 10 + 1= y_1 - 1 + 1 [/tex]

[tex] 11 = y_1 [/tex]

[tex] y_1 = 11 [/tex]

Coordinates of D is (7, 11)

The explicit function that represents Mark's salary is;

[tex]y = \$ 65,000 \times (1.02)^x[/tex]

Step-by-step explanation:

The given parameters are;

The amount Mark will make at annually as an engineer = $65,000

The percentage annual pay increase guaranteed by the company = 2%

The explicit function that represents Mark's salary can be presented as follows;

Let Mark's present salary = y

Therefore we have;

y = $65,000× (1 + 0.02)ˣ = $65,000× (1.02)ˣ

Mark salary, y at a particular year, x is y = $65,000× (1.02)ˣ.

The value of,

1.  AB = 3x + 6 BC = 2x + 14 then, AC = 5x + 20

2. AB = 5x – 8 BC = 16 - 3x then, AC = 2x + 8

3. AC = 3x - 1 BC = 12-X then, AB = 4x - 13

4.  AB = 2x + 11 BC = 4x - 5 then AC = 6x + 6

5. AC = 6x-4 BC = 4x - 3 then AB = 2x - 1

What is Midpoint?

Midpoint is the point in the middle of the two endpoints of a line segment.

Now, B is midpoint of AC.

Then, AC = AB + BC

1. AB =  3x + 6, BC = 2x + 14

Then, AC = 3x + 6 + 2x + 14

         AC = 6x + 20

2. AB = 5x – 8,  BC = 16 - 3x

Then, AC = 5x - 8 + 16 - 3x

        AC = 2x + 8

3. AC = 3x - 1,  BC = 12-x

Then, AB =( 3x -1 ) - ( 12 - x )

        AB = 2x - 13

4.  AB = 2x + 11, BC = 4x - 5

Then, AC = 2x + 11 + 4x - 5

        AC = 6x + 6

5.  AC = 6x-4,  BC = 4x - 3

Then, AB = (6x - 4) - (  4x - 3 )

        AB = 2x - 1

Answer:

40%

Step-by-step explanation:

The probability of the arrow landing on the green section is a 40% chance

This is because there are only 3 sections where one is 50 and the other is 10

To find the green we can create an equation, where x = green section

50 + 10 + x = 100

The equation equals 100 because that's the highest the percentage will go in probability, unless we were told otherwise

60 + x = 100

x = 100 - 60

x = 40

I hope this helps!

Answer: q=27

Step-by-step explanation:

Given

Combine like term in the parentheses

5×24-5q=-15

Combine like term by multiplication

120-5q=-15

Subtract 120 on both sides (subtraction property of equality)

120-5q-120=-15-120

-5q=-135

Divide -5 on both sides (division property of equality)
