Answer:

14/3

Step-by-step explanation:

Set up two ratios and cross multiply. Solve for missing segment.

[tex]\frac{2}{3}[/tex] = [tex]\frac{x}{7}[/tex]

3x = 14

x = 14/3

Step-by-step explanation:

please, write the problem statement properly. it is not clear what you are asking for.

for example, the way how you wrote it, the first expression would be

58 × 5 - 6

and that would be (remember, multiplication and division happen before any additions or subtractions)

58 × 5 - 6 = 290 - 6 = 284

nothing on the right side of numbers fits to that.

so, I am speculating. did you mean

58 × (5-6) ?

in that case we get

58 × (5-6) = 58 × (-1) = -58

and then I assume that the right side of all the numbers includes also operations (like +, -, ...), as I see no -58 in the list of numbers.

and then I just propose that the right side could look like

-2×5 - 48 (which would also be -58).

but again, this could be something completely different.

so, please, write your problem statement again. and carefully.

Answer:

ASA

Step-by-step explanation:

Given the lines, we know ED = CD

Given the right angles, we know angle DEF = angle BCD

Because angles BDC and FDE are on the same line, and are opposite of each other, those are congruent as well

Answer:

a = 1/8

b = 8

Step-by-step explanation:

a (1/2) ^3 = (1/2) *(1/2) * (1/2) = 1/8

b( 1/2 ) ^ -3  The negative exponent means 1 / (1/2)^3  = 1/ (1/8) = 8

Answer:

Option (1)

Step-by-step explanation:

Given figure in the picture has two parallel sides and fulfilling the property of a trapezium.

Since, an isosceles trapezium contains two parallel sides and other pair of the sides are equal in length.

Therefore, the given trapezium can't be an isosceles trapezium.

Option (1) will be the correct option.

Answer:

a). 2700

b). 385.7

Step-by-step explanation:

According to the Question,

Given that, Adwoa received a commission of 20% on the bread she sold. In one week, Adwoa's commission was 540.

let x be the total cost of bread she sells during the week.

a). Thus, 20% of x = 540

x = 540 × (100/20)  ⇒ 2700 is the total cost of bread she sells during the week.

b). Now, her average daily commission is 2700/7 ⇒ 385.7

Answer:

b

Step-by-step explanation:

The roots of the quadratic equation x² + 3x - 6 = 0 are, x = [- 3 + √(33)]/2,

x = [- 3 - √(33)]/2.

A quadratic equation is an algebraic expression in the form of variables and constants.

A quadratic equation has two roots as its degree is two.

We any to find any types of roots of a quadratic equation, real, complex or imaginary we use the formula,

[- b ± √(b² - 4ac)]/2a.

Therefore, The roots of the quadratic equation x² + 3x - 6 = 0 is,

x = [- 3 ± √(3² - 4×1×-6)]/2×1.

x = [- 3 ± √(9 + 24)]/2.

x = [- 3 ± √(33)]/2.

Answer:

Step-by-step explanation:

A =1/2 *h (x+y)

A =hx+hy/2

A*2 =hx+hy

2A =hx+hy

2A - hy = hx

(2A -hy)/h = x

Answer:

x = [tex]\frac{2A-hy}{h}[/tex]

Step-by-step explanation:

Given

A = [tex]\frac{1}{2}[/tex] h(x + y) ← multiply both sides by 2 to clear the fraction

2A = h(x + y) ← distribute

2A = hx + hy ( subtract hy from both sides )

2A - hy = hx ( divide both sides by h )

[tex]\frac{2A-hy}{h}[/tex] = x

Answer:

L ACB = 25 ( L at centre = 2× L at circumference)

prove

sum = 75

centre = 50

then L AOB +ACB = 75

50 + L ACB =75

L ACB = 75 - 50

then L ACB= 25

Answer:

p = 1/2

Step-by-step explanation:

(4p - 1)^2 =(2p)^2

4p - 1 =[tex]\sqrt{(2p)^2}[/tex]

4p - 1 =2p

4p - 2p =1

2p = 1

p =1/2

absolute value is like asking for "how much away from zero", so -5 is 5 away from zero.

The graph of the function is increasing when x>0.

Graph a diagram showing the relation between variable quantities, typically of two variables, each measured along one of a pair of axes at right angles.

here, we have,

We know, cube root parent is:

The basic parent cube root function is of the form f (x) = ∛x. It increases on the interval (-∞, ∞). It increases on the interval [0, ∞). It is positive on (0, ∞) and negative on (-∞, 0). It is a non-negative function always (on [0, ∞)). Its absolute min is 0 but no absolute max. Its domain and range is the set of all real numbers.

Given,

The function f(x) = ∛x

Let x = 1, we get f(x) = 1,

x =2, f(x) = 8

if x =3, f(x) = 27.

As we know, with increase in the value of x, the value of f(x) is also increasing.

Step-by-step explanation:

Answer:

A. [tex]2x^2y\sqrt[3]{7xy^2}[/tex]

Step-by-step explanation:

When given the following problem,

[tex]\sqrt[3]{56x^7y^5}[/tex]

The problem asks one to find the cube root of the value under the radical. The cube root of a number is essentially a value that must be multiplied by itself three times to get the result under the radical. An easy way to do this is to prime factorize the value under the radical sign. This will allow one to see the components of the number, thus making it easier to take value out of the radical;

[tex]=\sqrt[3]{7*2^3x^7y^5}[/tex]

Now divide each of the exponents by (3), write the whole result outside the radical, and the remainder under the radical,

[tex]=2x^2y\sqrt[3]{7xy^2}[/tex]

Answer:

200 cubic centimetres

Step-by-step explanation:

Length = [tex]20 \: cm[/tex]

Width = [tex]6 \: cm[/tex]

Height = [tex]5 \: cm[/tex]

Volume = [tex] \frac{1}{3} \times w \times l \times h[/tex]

[tex] = \frac{1}{3} \times 20 \times 6 \times 5[/tex]

[tex] = \frac{20}{3} \times 6 \times 5[/tex]

[tex] = \frac{20}{3} \times (3(2)) \times 5[/tex]

[tex] = 20 \times 2 \times 5[/tex]

[tex] = 40 \times 5[/tex]
