Answer:

Peppa does not know

Step-by-step explanation:

Answer:

r=85

Let's solve your equation step-by-step:

−6(r−98)=78

Step 1: Simplify both sides of the equation

−6(r−98)=78

(−6)(r)+(−6)(−98)=78(Distribute)

−6r+588=78

Step 2: Subtract 588 from both sides

−6r+588−588=78−588

−6r=−510

Step 3: Divide both sides by -6

−6r/−6=−510/−6

r=85

Answer:

r=85

Answer:

85

Step-by-step explanation:

–6(r − 98) = 78

expand:

-6r+588=78

588-78=510

6r=510

510÷=85

Option 3

Step-by-step explanation:

-2/3 since the line is a total of 3 the 2 is negative which would make it the answer meaning that is the only negative option.

Answer:

512.

Step-by-step explanation:

8 cubed is the same as 8 to the third power.

We usually use other ways to represent certain number to the power to help make equations easier and write less so,

instead of saying: 2 to the second power; we say 2 squared.

Instead of saying 2 to the third power; we say 2 cubed.

The number 2 was used just as example, it could be any number.

so 8 cubed = 8 to the third power so,

8 cubed = [tex]8^{3}[/tex] = 8x8x8 = 512

Answer:

$20.96

Step-by-step explanation: 6.45 times three equals 19.35 plus a quarter of 6.45 equals 1.6125 which you round to 1.61. So 19.35+1.61= 20.96

Answer:

the cost of 1 child ticket is $6.5 and the cost of 1 adult ticket is $9.5

Step-by-step explanation:

Given that:

the price of 4 adult tickets & 6 child tickets = $77

the price of  6 adult tickets & 4 child tickets = 83

then the price of 1 adult ticket and 1 child ticket will be:

Let assume that the cost of 1 adult ticket to be $p

Then;

the cost of 4 adult ticket = $4p

Similarly, the cost of 6 adult ticket = $6p

However, assuming that the cost of 1 child ticket is $q

Then;

the cost of 6 child ticket = $6q

the cost of 4 child ticket = $4q

∴

We can express them with their given prices that:

4p + 6q = 77    --- (1)

6p + 4q  = 83   --- (2)

From equation (1), let 4p = 77 - 6q

Then; [tex]p = \dfrac{77 - 6q}{4}[/tex]

replace the value of p into equation (2)

∴

[tex]6 \Big ( \dfrac{ 77 - 6q }{4}\Big) + 4q = 83[/tex]

[tex]\dfrac{462 - 36q}{4}+ 4q = 83[/tex]

[tex]115.5 - 9q + 4q = 83 \\ \\ 115.5 -5q= 83 \\ \\ 115.5 - 83 = 5q \\ \\ 32.5 = 5q[/tex]

[tex]q= \dfrac{32.5}{5}[/tex]

q = 6.5

Since q = 6.5, then using equation (1)

4p + 6(6.5) = 77

4p +39 = 77

4p = 77 -39

4p = 38

p = 38/4

p = 9.5

Thus, the cost of 1 child ticket is $6.5 and the cost of 1 adult ticket is $9.5

Answer:

V = 1692.46 m3

Step-by-step explanation:

V = π· r2· h

V = π· 72· 11

V = 1692.46 m3

Answer:

Step-by-step explanation:

A=2*π*r*h+2*π*r^2    ( This is the formula for surface area of cylinder )

As given

base = 11m    so we have to get the radius = 11/2 = 5.5m

height=7m

now putt in formula, we get

=2*π·*(5.5)*(7)+2*π*(5.5)^2

=431.96899m^2

She ordered 64 markers.

Step-by-step explanation:

She ordered 16 boxes with 32 pencils inside totaling 512 pencils altogether.

32 x 16 = 512 pencils

She there were 8 times as many pencils as markers.

   markers =  512 pencils/8=64 markers

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

Answer: 10

Step-by-step explanation:

Question A:

The formula to find the hypotenuse is c²=a²+b²

So you would insert the numbers into the formula which would be c²=8²+6²

8²=64

6²=36

36+64=100

So c²=100

Then you want to find c on its own so you have to square root 100.

The square root of 100 is 10.

You have to use this method for the rest of the triangles.

The hypotenuse of the triangles are solved

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the measure of sides of the triangle are

a)

a = 8

b = 6

Now , From the Pythagoras Theorem , The hypotenuse² = base² + height²

c = √ ( 8 )² + ( 6 )²

c = √100 ≈ 10

b)

a = 11

b = 7

c = √170 ≈ 13.0

c)

a = 13

b = 6

c = √205 ≈ 14.3

Hence , the hypotenuse of the triangles are solved
