Consider the following prisms, whose bases are both squares.

Naomi tried to use Cavalieri's principle to show that the two figures have the same volume.
"The base areas are the same. Therefore, corresponding cross-sections have the same area. So the volumes must be the same."
What is the first mistake Naomi made?

Answer:

107

Step-by-step explanation:

180-(65+42) = SQR = 73

180-73 = 107

Answer:

Option 3 is the correct answer

Answer:

x=-7, x=3

Step-by-step explanation:

Seperate into possible cases

Solve the equation

Answer:

x = 3    or x = -7

Step-by-step explanation:

(x + 2)^2=25

Take the square root of each side

sqrt((x + 2)^2)=sqrt(25)

x+2 = ± 5

Subtract 2 from each side

x+2-2 = -2 ±5

x = -2 +5  or x = -2 -5

x = 3    or x = -7

Answer:

31 : 41

Step-by-step explanation:

Given that Ravi's mass is 31kg . And his brother is 10 kg heavier than him . So his weight will be 31kg + 10kg = 41kg. So we have ,

[tex]\begin{cases}Mass \ of \ Ravi = 31kg \\ Mass of Brother \ = \ 41kg \end{cases}[/tex]

Therefore their total mass = 31 + 41 = 72 kg .

Therefore the ratio will be 41:72 .

The ratio of Rajar's mass to their total mass is 41:72.

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Given that, Ravi's mass is 31 kg.

His brother, Rajar, is 10 kg heavier than Ravi.

Weight of Rajar is 31+10=41 kg

Total weight =31+41

= 72 kg

The ratio of weights = 41:72

Therefore, the ratio of Rajar's mass to their total mass is 41:72.

Step-by-step explanation:

Answer:

A() it is located _25 and is the right of point A on the number line

Answer:

The Answer is C

Step-by-step explanation:

so if u draw out a number line, point A will be on the left side of the number line or in this case "0". So it is saying "point b is 5 less than point A" so since Point A is "-20" and it says "5 less than point A" so it would be adding up 5 more to -20 so it would be -25. But if it was 5 more than point A it would have been -15. If u take an example of money, like if u owe someone $20, it would be -$20 in your balance, and if he or she says u need to owe me 5 more $'s cuz there was damage now in your balance it would be -25.

Answer: = £135

Step-by-step explanation:

Original price = 100%

Percentage increase = 20%

New price = 100% + 20% = 120%

If 120% = £162

What about 100% = ?

= (100 x 162) ÷ 120

= 16200 ÷ 120

= £135.

Answer:

B (39)

Step-by-step explanation:

Using the Pythagorean theorem (a^2+b^2=c^2) and X=BC length

15^2+36^2=x

225+1296=x

√1521=x

x=39

Answer:

B.

Step-by-step explanation:

The Pythagorean Theorem

a^2+b^2=c^2

In this case it's c^2=a^2+b^2

c^2=15^2+36^2

c^2=225+1296

c^2=1521

c= the square root of 1521

c=39

So...

the length of line segment BC is 39

Answer:

A

Step-by-step explanation:

for the number to be greater than 11 x cannot be negative so we can rule out C and D. 0 does not work as x so we can rule out B. we are left with A as the answer.

Step-by-step explanation:

the rate of change in A

10-5/4.5-3 .5

=5.

but where is the function B??

just pick two y values and it's corresponding x values

the rate of change is equal to the gradient .

change in y values divided by change in the x values.
