Answer:

Question 5: x = 12, Question 6: y = 2[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Use the Pythagorean Theorem to calculate missing sides.

Question 5 explanation: [tex]x^{2} + 9^2 = 15^2[/tex]n:  ⇒ [tex]x^{2} + 81 = 225[/tex] ⇒ [tex]x^{2} = 144[/tex] ⇒ [tex]x=12[/tex]

Question 5 explanation: [tex]y^{2}+6^2 =(4\sqrt{3})^2[/tex] ⇒ [tex]y^{2} + 36 = 48[/tex] ⇒ [tex]y^2 = 12[/tex] ⇒ [tex]y=2\sqrt{3}[/tex]

Answer:

x = -8

Step-by-step explanation:

11x– 1 = -89

Add 1 to each side

11x– 1+1 = -89+1

11x = -88

Divide each side by 11

11x/11 = -88/11

x = -8

Answer and explanation:

The surface area of a solid is the sum of the areas of all faces of the solid. The surface area of a cube is calculated using the formula 6a² since a cube has 6 faces in total likewise a cuboid.

We can say the rectangular solid is a cuboid and to find the surface area of the cuboid we add up the surface area of all 16 cubes

Surface area is therefore 16×6a²

Answer:

Pack of 6

Step-by-step explanation:

Pack of 4 = £1

Packs of 6 = £1.20

Price per unit of each pack:

Pack of 4 ;

Unit price : cost / units

Unit price = £1 / 4 = £0.25

Pack of 6 ;

Unit price : cost / units

Unit price = £1.20 / 6 = £0.20

Pack of 6 is the best value for money as it has a lower unit price

[tex] \frac{7}{4} d = 14[/tex]

[tex]d = 14 \times \frac{4}{7} [/tex]

[tex]d = 8[/tex]

Hence, required value of d is 8.

Answer:

Answer:

Cannot be determined

Step-by-step explanation:

You cannot assume the function travels down infinitely, because the function is not given to you. The graph could go up down left or right for all you know, you just cannot see it.

Answer:

Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.

Point Form:

(0,2)

Equation Form:x=0, y=2

Answer:

(0,2)

Step-by-step explanation:

Multiply each equation by the value that makes the coefficients of  y  opposite.

3*2x-y=3*-2

Simplify

6x-3y=-6

Add the two equations

10x = 0

Divide both by 10 and simplify

x=0

Substitute x into the equations.

4*0+3y=6

3y=6

2

y=2

Answer:

6 elephants and 3 kangaroos in the zoo.

Step-by-step explanation:

Number of animals = 9

Number of legs seen = 30

But an elephant has 4 legs, while a kangaroo has 2 legs.

Let the number of elephant be represented by E, and the number of kangaroo by K.

So that,

E + K = 9 .................. 1

4E + 2K = 30 ............. 2

Multiply equation 1 by 2 to have

2E + 2K = 18 ............ 3

Subtract equation 3 from 1

2E = 12

E = 6

Substitute the value of E in equation 1

E + K = 9

6 + K = 9

k = 3

Thus, there were 6 elephants and 3 kangaroos in the zoo.

Answer: 710,000 kg

Step-by-step explanation:

There are 100 pence in one pound.

The number of two pence coins in 1 pound is therefore:

= 100 / 2

= 50 coins

In 2 million pounds therefore, there will be:

= 50 * 2,000,000

= 100,000,000 two pence coins

If one coin weighs 7.1g, weight is:

= 100,000,000 * 7.1

= 710,000,000 g

A kg is 1,000 grams so the weight in kg is:

= 710,000,000/1,000

= 710,000 kg

Answer:

1,763.6

Step-by-step explanation:

There is no hundredths place, therefore the number would just stay the same.  

The decimal number 1,763.6 rounded to the nearest hundredth will remain the same.

The action of forming anything into a circle. Mathematics. the act of substituting a number with one that is roughly equivalent in value but has fewer digits: To the closest dollar, rounding $27.68 results in $28. a comparable procedure that identifies one of several rules.

The decimal number is given below.

⇒ 1,763.6

In the decimal number, there is no hundredth place, therefore the number would just stay the same.
