Answer:

Alandra can fill 60 whole cones

Step-by-step explanation:

The volume of a rectangular prism is V = L × W × H, where

The volume of the cone is V = [tex]\frac{1}{3}[/tex] π r² h, where

∵ Alandra's rectangular cake pan is 33 cm by 23 cm

∴ L = 33 cm and W = 23 cm

∵ She has enough cake batter to fill it to a depth of 3 cm.

∴ H = 3 cm

→ Find the volume of the batter using the 1st rule above

∵ V = 33 × 23 × 3

∴ V = 2277 cm³

∵ Alandra wants to pour the batter into ice cream cones

∵ She plans to fill each cone to a depth of 9 cm with a diameter of 4 cm

∴ h = 9 cm

∵ r = [tex]\frac{1}{2}[/tex] diameter = [tex]\frac{1}{2}[/tex] (4)

∴ r = 2 cm

→ Substitute them in the 2nd rule above to find the volume of each cone

∵ V = [tex]\frac{1}{3}[/tex] (π) (2)² (9)

∴ V = 12π cm³

→ To find the number of cones divide the volume of the batter by

   the volume of each cone

∵ Number of cones = 2277 ÷ 12π

∴ Number of cones = 60.3993

→ We will take the whole number only because we need the whole cones

∴ Alandra can fill 60 whole cones

Answer:

50 mph

Step-by-step explanation:

drive to reach their grandmother's house in 4 hours

Given that:

Miles driven = 550 miles

Miles already driven = 350 miles

Miles left to drive = (550 - 350) miles = 200 miles

To reach destination in 4 hours

Speed in miles per hour will be :

Distance / time

= 200 miles / 4 hours

= 50 miles / hour

Answer:

50 mph

[tex]\frac{1}{3} =\frac{x}{15}\\3x=15\\x=5[/tex]

Answer:

Step-by-step explanation:

Notice that, the angle QRS is external to the triangle and adjacent to the angle PRQ. According to the theorem of a external/adjacent angle, we have: m∠QRS = m∠PQR + m∠RPQ, where PQR and RPQ are internal angles.

From the hypothesis, we have:

m∠QRS =(10x−12)∘(10x−12)

m∠PQR = (3x+20)∘(3x+20)

m∠RPQ=(3x−8)∘(3x−8)

Using the first equation and replacing the hypothesis:

m∠QRS = m∠PQR + m∠RPQ

(10x−12)∘(10x−12) = (3x+20)∘(3x+20) + (3x−8)∘(3x−8)

Multiplying and applying the remarkable identity:

Then, we use a calculator to find the roots, which are:

In this case, we will see what root is the right one.

Now, we replace it into m∠QRS =(10x−12)∘(10x−12), because we need to find m∠QRS.

m∠QRS =(10x−12)∘(10x−12) = (10(4.7) - 12) (10(4.7) - 12) = (35) (35) = 1225

Answer:

6 games

Step-by-step explanation:

Joey has won 3 out of the last 8 games of cards he has played with his brother. They play 16 more games, how many of those games does Joey expect to win?

8 games = 3 won

16 games = x

Cross Multiply

8x = 16 × 3

8x = 48

x = 48/8

x = 6

If they play 16 more games, Joey expects to win 6 games

Answer:

6 games

Step-by-step explanation:

2 x 8 = 16 so, if he won 3 out of 8 he will expect to win another 3 games.

Answer:

1) 25%

2) 555.56

3) 10%

4) 700

Step-by-step explanation:

1) 35 is what percent of 140

This is calculated as:

35/140 × 100

= 25%

2) 250 is 45% of what number?

Let the number be represented as x

This is calculated as:

45% of x = 250

45/100 × x = 250

45x /100 = 250

Cross Multiply

45x = 250 × 100

x = 25000/45

x = 555.55555556

x = 555.56

3) 74 is what percent of 740?

Let the percentage be represented by x

x% × 740 = 74

Divide both side by 740

x% = 74/740

x% = 0.1

Converting to percentage

0.1 × 100 = 10%

4) 350 is 50% of what number?

Let the number the represented by x

This is calculated as:

50% of x = 350

50/100 × x = 350

50x /100 = 350

Cross Multiply

50x = 350 × 100

x = 35000/50

x = 700

x = 555.56

Answer:

Y=6 and x=1

Step-by-step explanation:

y=6x

∴y-6x=0

and 7x-8y=-41

Suppose,

-6x+y=0→(1)

and 7x-8y=-41→(2)

Taking equation (1), we have

-6x+y=0

⇒y=6x→(3)

Putting y=6x in equation (2), we get

7x-8y=-41

7x-8(6x)=-41

⇒7x-48x=-41

⇒-41x=-41

⇒x=1→(4)

Now, Putting x=1 in equation (3), we get

y=6x

⇒y=6(1)

⇒y=6

∴y=6 and x=1

Answer:

t = 7 or t = -1

Step-by-step explanation:

You can use a calculator or:

t² - 6t = 7

-> t² - 6t -7 = 0

-> t² - 7t + t - 7 = 0

-> t(t-7) + (t-7) = 0

-> (t-7) . (t+1) = 0

-> t = 7 or t = -1

Answer:

T = 7

Step-by-step explanation:

How you find T is by multiplying different numbers and squaring them by subtracting until you get to the number that equals to 7

Step-by-step explanation: i hoped it helped ;)

Given:

Polynomial = P(x) = 3x² + kx + 6

Factor of the ablove polynomial = (x+3)

To Find:

Value of K, for which (x+3) become the factor of P(x) = 3x² + kx + 6

Solution :

Now,

x + 3 = 0

⇒x = (-3)

So,

As (x+3) is a factor so x = (-3) is one root of the polynomial.

Therefore,

P(-3) = 0

→ P(-3) = 3(-3)² + k(-3) + 6 = 0

→ 3(9) - 3k + 6 = 0

→ 27 - 3k + 6 = 0

→ 27 + 6 - 3k = 0

→ 33 - 3k = 0

→ - 3k = -33

→ k = -33 ÷ -3

→ k = 11

3x²+ kx + 6, by putting the value of k = 11 and taking -3 as root the remainder should be zero

→ 3x²+ 11x + 6

→ 3(-3)² + 11(-3) + 6

→ 3(9) - 33 + 6

→ 27 - 33 + 6

→ 27 + 6 - 33

→ 33 - 33

→ 0

Hence verified !

Step-by-step explanation:

doing the edge 2020 assignment right now

The correct answer are option (A) , (B), (C) and (D)

[tex]f(x) = 5(\sqrt[3]{16} )^x[/tex]

[tex]f(x) = 2.3(8)^\frac{1}{2}[/tex]

[tex]f(x) = 81^\frac{x}{4}[/tex]

[tex]f(x) = \dfrac{3}{4} (\sqrt{27} )^x[/tex]

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

The operator that perform arithmetic operation are called arithmetic operators .

Operators which let do basic mathematical calculation

+ Addition operation : Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation : Subtracts right hand operand from left hand operand.

for example 4 -2 = 2

* Multiplication operation : Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation : Divides left hand operand by right hand operand

For example 4/2 = 2

Given exponential functions :

[tex]f(x) = 5(\sqrt[3]{16} )^x[/tex]

[tex]f(x) = 2.3(8)^\frac{1}{2}[/tex]

[tex]f(x) = 81^\frac{x}{4}[/tex]

[tex]f(x) = \dfrac{3}{4} (\sqrt{27} )^x[/tex]

[tex]f(x) = (24)^\frac{1}{3}^x[/tex]

Simplification of the given exponential functions :

[tex]f(x) = 5(\sqrt[3]{16} )^x = 5(\sqrt[3]{2^3\times2} )^x = 5(2\sqrt[3]{2} )^x[/tex]

[tex]f(x) = 2.3(8)^\frac{1}{2} = 2.3(2^3)^\frac{1}{2}^x = 2.3.2(2)^\frac{1}{2}^x = 24.(2)^\frac{1}{2}^x[/tex]

[tex]f(x) = 81^\frac{x}{4} = f(x) = (3^4)^\frac{x}{4} = 3^x[/tex]

[tex]f(x) = \dfrac{3}{4} (\sqrt{27} )^x = \dfrac{3}{4} (\sqrt{3^3} )^x = \dfrac{3}{4} 3^x[/tex]

[tex]f(x) = (24)^\frac{1}{3}^x = 2(2)^\frac{1}{3}^x[/tex]

Hence, the correct answer are option (A) , (B), (C) and (D)

[tex]f(x) = 5(\sqrt[3]{16} )^x[/tex]

[tex]f(x) = 2.3(8)^\frac{1}{2}[/tex]

[tex]f(x) = 81^\frac{x}{4}[/tex]

[tex]f(x) = \dfrac{3}{4} (\sqrt{27} )^x[/tex]

Answer:

54 km/h

Step-by-step explanation:

Step one:

given data

We are required to perform unit from m/s km/h

from 15m/s to km/h

Step two:

1 meter= 1/1000 km,

1 seconds= 1/3600 hour

1m/s = 1/1000/1/3600= km/h= 3600/1000= 36/10= 18/5 km/h

so of 1m/s is equivalent to 18/5 km/h

then 15m/s is equivalent to x

cross multiply

x= 15*18/5

x= 3*18

x=54 km/h
