Answer:p=12

Step-by-step explanation:

(9p)+(p+21)+(p+27)=180

9*12=108

12+21=33

12+27=39

108+33+39=180

so p=12

Answer:

Well, -1-126 (-12b - 6 + 9b - 18) equals 378b + 2023.

Step-by-step explanation:

Subtract numbers:

−1−126 (−12−6+9−18)

−1−126 (−12−24+9)

Combine like terms:

−1−126 (−12−24+9)

−1−126 (−3−24)

Then you'll have to distribute:

−1−126 (−3−24)

−1+378 + 3024

Hope this helps        :)

Answer:

1.The formula to convert Celsius to Fahrenheit is:

F = 1.8 C + 32

Multiply the Celsius temperature by 1.8.

Add 32 to this number.

Report the answer in degrees Fahrenheit.

Example: Convert 20°C to Fahrenheit.

F = 1.8 C + 32

F = 1.8 (20) + 32

1.8 x 20 = 36 so F = 36 + 32

36 + 32 = 68 so F = 68°F

20°C = 68°F

Answer:

a) 412.5g

b)23m²

Step-by-step explanation:

a)18m²=675g

11m²=x

by cross multiplication,

18x=11×675

18x=7425

x=7425/18

x=412.5g

b)18m²=675g

y=862.5g

18×862.5=675y

15525=675y

15525/675=y

y=23m²

Answer:

Step-by-step explanation:

This is a rate problem so using ratios is a good way to calculate the answer for different areas or amounts

     675 g per 18 m²       675/18     g/m²

a)  How many grams for 11m²

     675/18  g/m²   =   ??? / 11 m²            i cross multiply 675 times 11 divide by 18

                                                         or more simply multiply both side by 11

                                                         solving for the ???

            (675)(11) g m² / 18 m²  =  ??? g    =  412.5 grams    ( the m²/m² cancel)

b)  what area can be fertilised with 862.5 g?         again applying ratio

      this time we know the g and want to calculate an unknown area

      675 / 18  = 862.5  / ???        this will take one more step since the ??? is

                                                    in the denominator

      18 / 675  =  ??? / 862.5       I just inverted both sides

      18m² / 675g = ??? / 862.5g      again simply multiply both sides by 862.5g

     (18m²)(862.5g) / (675g) = ???          this time the grams cancel leaving m²

                                 ???   =   23 m²

Answer:

the discount is 43.35 or the final price $7.65

Step-by-step explanation:

Discount = Original Price x Discount %/100

Discount = 51 × 85/100

Discount = 51 x 0.85

You save = $43.35

Final Price = Original Price - Discount

Final Price = 51 - 43.35

Final Price = $7.65

Answer:

Step-by-step explanation:

Triangles EFG and FGH are similar.

x/15 = 36/39

x/15 = 12/13

x = 15*12/13 = 180/13 ≈ 13.8 units

The required measure of x is given as 5.8 in the given triangle.

The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°.

Similar triangles are triangle that has a relationship as of some scale factor.

here,
From the figure,
From triangle GHF and triangle EGF
x / 15 = 15 / 39
x = 225 / 39
x = 5.8

Thus, the required measure of x is given as 5.8 in the given triangle.

Answer:

Lateral surface area = 280 square inches

Step-by-step explanation:

Lateral surface area of a prism = (Perimeter of the base) × height of the prism

Perimeter of the base = 8 + 15 + 17

                                     = 40"

Height of the prism = 7"

Therefore, Lateral surface area of the prism = 40 × 7

                                                                         = 280 square inches

1st most = 8.43 inches

2nd most = 5,426 Seconds

3rd most = 1580 meters

4th most = 1500 grams

Step-by-step explanation:

8.43 inches = 0.7025 feet is most precise as it rounded to 0.7 feet it wouldn't be precise enough.

5,426 Seconds =  01:30:26. hrs mins sec can be converted.

1580 meters = 1.58 km = 158000cm  hasn't been properly converted as zeros get lost.

Answer:

n = 2

Step-by-step explanation:

sin 30° = ½

tan 45° = 1

then

sin 30° : tan 45° = 1 : n

½ : 1 = 1 : n

n = 2

The value of n for the trigonometric expression will be n = 2

The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.

The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.

Given that the ratio sin 30°: tan 45º can be written in form 1: n. The value of n will be calculated as:-

sin 30° = ½

tan 45° = 1

Then,

sin 30° : tan 45° = 1 : n

½ : 1 = 1 : n

n = 2
