Answer:

a^2 + b^2 + c^2 + 2ab + 2bc + 2ca

Answer:

£1999.85

Step-by-step explanation:

A = P(1 + rt)

Where:

A = Amount after t years

P = Initial amount invested = £1850

r = Interest rate = 2.7%

t = Time in years = 3 years

Calculation:

First, converting R percent to r a decimal

r = R/100 = 2.7%/100 = 0.027 per year.

Solving our equation:

A = £1850(1 + (0.027 × 3))

A = £1999.85

Therefore, Brian will have £1999.85 after 3 years.

Answer/Step-by-step explanation:

Given:

m<4 = 131°

a. m<8 = 180 - m<4 (linear pair)

m<8 = 180 - 131 (substitution)

m<8 = 49°

b. m<5 = m<4 (alternate exterior angle are congruent)

m<5 = 131° (substitution)

c. m<2 = m<5 (vertical angles are congruent)

m<2 = 131° (substitution)

d. m<1 = m<8 (vertical angles are congruent)

m<1 = 49° (substitution)

e. m<6 = m<1 (vertical angles are congruent)

m<6 = 49° (substitution)

f. m<7 = m<4 (vertical angles are congruent)

m<7 = 131° (substitution)

Answer:

y= 1330

Step-by-step explanation:

it might be wrong but

-4x -7.5 = 3312.5

4x +4y = 2000      (x cancels out)

4y -7.5 = 5312.5

4y = 5320

y= 1330

Answer:

Step-by-step explanation:

This is because 4 ft x 8 ft = 24 feet

24 feet times 12 (this is because there 12 inches in a foot)

288 inches

Answer:

8 m = width

28 m = length

Step-by-step explanation:

Let w = width

3w + 4 = length

P =  2w + 2l

  = 2w + 2(3w + 4) = 72

     2w + 6w + 8 = 72

      8w + 8 = 72

       8w = 64

         w = 8 m = width

3w + 4 = 24 + 4 = 28 m = length

Answer:

Gcf 9

Step-by-step explanation:

Factors of 27y^3z = 1,3,5,9,27,y,y^2. Factors of 45x^2y = 1,3.5,9,15,45,x,y. CF = 1,3,5,9,y. GCF = 9.

Answer:

Your answer is 105km travelled in 7 hours.

Step-by-step explanation:

Divide 150km by 10 to find the amount of km travelled in 1 hour. Then multiply that answer by 7.

Answer:

Choice 1) 181.5 mm

Step-by-step explanation:

41.5+55+85 = 181.5

Answer:

0.92

Step-by-step explanation:

take the 8 away from 100 = 92

then divide the 92 by 100

then you have your answer 0.92

Answer:

p < 24

Step-by-step explanation:

Given: -9 + p < 15

Add 9 to both sides.

p < 24

Step-by-step explanation:

10 + 5x = 10 + 5(15)

= 10 + 75

= 85°

4x - 10 = 4(15) - 10

= 60 - 10

= 50°

6x - 5 = 6(15) - 5

= 90 - 5

= 85°

Answer:

4/9

Step-by-step explanation:

8/18 x 7/17 x 6/16 = 336/4896 = 0.06863 = 6.863% = 6.9\%

≈0.06863=6.863%≈6.9%

Answer:

Step-by-step explanation: he standard form to find the value of X in multiplication operation is. Divisor × Dividend = Product. Let us take dividend = x, Divisor × x = Product. Then the formula to find the value of x is. X = product / Divisor

Answer:

x = 99

Step-by-step explanation:

4 sided polygon = 360 degrees

92 + 68 + 101 + x = 360

261 + x = 360

-261        -261

x = 99

Hope this helped! Have a nice day! Plz mark as brainliest!!!

Answer:

The length of the bold arc is approximately 13.4 mi

Step-by-step explanation:

The radius of the circle having the arc, r = 17 mi

Therefore, the circumference of the circle, 'C', is given as follows;

C = 2·π·r

∴ C = 2×π×17 = 34·π

The angle subtended by the arc = 45°

The sum of the angles at the center of the circle = 360°

By similarity, the ratio of the length of the bold arc to the circumference of the circle = The ratio of the angle subtended by the arc to the sum of the angles at the center of the circle

Mathematically, we have;

[tex]\dfrac{The \ arc \ length}{C} = \dfrac{\theta}{360^{\circ}}[/tex]

Therefore, we get;

[tex]\dfrac{The \ arc \ length}{34 \cdot \pi} = \dfrac{45 ^{\circ}}{360 ^{\circ}} = \dfrac{1}{8}[/tex]

[tex]{The \ arc \ length}{} = \dfrac{1}{8} \times 34 \cdot \pi = 4.25 \cdot \pi[/tex]

The length of the bold arc = 4.25·π mi ≈ 13.4 mi (by rounding off the answer to the nearest tenth).
