number decreased by 8 is equal to 20

Answer:

Step-by-step explanation:

Total sum of degrees of a Triangle is 180 deg

Than: 8x-7 + x +7 + 2x + 15 = 180

11x + 15 = 180

x = (180-15) / 11  =15

Answer: 15

Answer:

16249.27392 cm³

Step-by-step explanation:

V = [tex]\frac{4}{3}[/tex] × π × r³

[tex]\frac{4}{3}[/tex] × 3.14 × 3.3³

Volume of 1 egg is 150.45624 cm³.

150.45624 cm³ × 108

16249.27392 cm³

Answer:

"so i need to find e missing side of each right triangle, side c is the hypotenuse!! a = 8.8ft, b= 9ft i have to round the answers to the nearest tenth if necessary "

Step-by-step explanation:

Sure! So remember that the Pythagorean theorem is a squared plus b squared = c squared.

= 8.8 squared + 9 squared = c squared

= 77.44 + 81 = c squared

[tex]\sqrt{158.44}[/tex] = c squared

c squared = (rounded) 12.6 ft

Answer:

x = 12

y = 6√3

Step-by-step explanation:

✅Apply the intersecting secant theorem to find x. Thus:

6(6 + x) = 7(7 + 8³/7)

Convert the mixed fraction to improper fraction

6(6 + x) = 7(7 + 59/7)

36 + 6x = 49 + 59

36 + 6x = 108

6x = 108 - 36

6x = 72

Divide both sides by 6

x = 72/6

x = 12

✅Apply the tangent-secant theorem to find y. Thus:

y² = 6(6 + x)

Plug in the value of x

y² = 6(6 + 12)

y² = 6(18)

y² = 108

y = √108

y = 6√3

Answer:

106

Step-by-step explanation:

all 3 of the angles add up to 360

you already know one is 164 and one is a right angle so

164 + 90 = 254

360 - 254 = 106

Step-by-step explanation:

all i am going to say is, Pythagorean theorem.

The volume of the square pyramid is 6 x 6 x 9/3 = 108 cubic cm.

Volume of the cube = 4 x 4 x 4 = 64 cubic cm

Number of cubes needed: 108/64 = 1 11/16 cubes (1.6875)

Answer:

Solution given:

square pyramid

each side of base[b]=6cm

height[h]=9cm

Volume of square pyramid[V]=[tex] \frac{1}{3 } {b}^{2} h \\ \frac{1}{3} {6}^{2} \times 9 = 108cm ^{3} [/tex]

now

length of cube [l]=4cm

volume of cube[v]=l³=4³=64cm³

now

no of wax needed=[tex] \frac{V}{v} [/tex]=[tex] \frac{108cm³}{64cm³} [/tex]=[tex] \frac{27}{16 } =1\frac{11}{16} [/tex]

Answer:

60,000

Step-by-step explanation:

Let us represent:

Costs price = x

Selling price = x - 25%x

x - 0.25x

= 0.75x

If it been sold for Rs 21,000 more then the profit would have been

10%. = x + 10% = 1.1x

1.1x =0.75x + 21000

Collect like terms

1.1x - 0.75x = 21000

0.35x =21000

x = 21000/ 0.35

x = 60000

The cost price of the item = 60,000

The formula calculates the cyclist's separation from the starting point, x, and will be x² = 5² + 3² - 2(5)(3)cos(140°).

Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.

This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.

As per the given information in the question,

From the cos law ;

x² = a² + b² - 2ab cos θ

The values obtained will be,

a =5

b =3

θ = 180° +70° -30°

θ = 180°- 40°

θ = 140°

Substitute the given values in the equation,

x² = a² + b² - 2ab cos θ

x² = 5² + 3² - 2(5) (3) cos(140°)

c) 2x^2y + 2xy^2

Explanation:

(x^2 y-3y^2+5xy^2)- (-x^2y+3xy^2-3y^2)

(x^2 y+5xy^2 -3y^2)- (-x^2y+3xy^2-3y^2)

x^2 y +5xy^2 -3y^2 + x^2y -3xy^2 + 3y^2

2x^2y + 2xy^2

The option C) 2x²y + 2xy² is equivalent to the given expression (x²y - 3y² + 5xy²) - (-x²y + 3xy² - 3y²).

Mathematically, an expression is an admixture of numbers, variables, operations, and functions that are conjoined according to peculiar rules to depict a mathematical calculation or association. It can be supposed to as a mathematical idiom or formula.

By combining numbers, variables, operators, and functions, mathematical expressions can define a broad lea of calculations and associations.

The given expression is (x²y - 3y² + 5xy²) - (-x²y + 3xy² - 3y²).

(x²y - 3y² + 5xy²) - (-x²y + 3xy² - 3y²)

= x²y - 3y² + 5xy² + x²y - 3xy² + 3y²

= 2x²y + 2xy².

Hence, option C) is correct in that 2x²y + 2xy² is equivalent to the given expression.
