Answer:

work out the area which is 4x5x3 this being 60 then divide this by 20 to get 3

The answer is 3kg

Answer:

[tex]density = mass \div volume \\ 20 = x \div 4 \times 3 \times 5 \\ 20 = x \div 60 \\ 20 \times 60 = x \\ x = 1200 \\ 1200 \div 1000 = 1.2kg[/tex]

Answer: X>3/5

Step-by-step explanation: because it doesent have a line under the greater than sign.   (: i hope that answers that!!

Answer:

Step-by-step explanation:

4/5

1/2

Answer:

3) 4:5  4) 1:2

Step-by-step explanation:

We just have to simplify the fraction of the smaller side of the smaller figure over the larger side.

For number 3) 12/15 = 3*4 / 3* 5 = 4/5

For number 4) 7/14 = 8/16 = 1/2

Answer:

The answer should be 9:25 am

Just subtract and use your fingers so you don’t loose track how many you subtracted

Answer:

count backward (use ur hands if needed cuz it's easier)...

6 - 9 so 5, 4, 3, 2, 1, 12, 11, 10, 9...

now we divide...

3/4 = .75

now we multiply...

60 x .75 = 45 mins

Step-by-step explanation:

6:00 p.m - 9 3/4 hour = 9:45 a.m...

hope this helps...

have a nice day!

Step-by-step explanation:

The solution of the expression will be 3⁵/₁₂.

Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication and division.

Given that the expression is 4¹/₄ - 5/6. The expression will be simplified as below,

E = 4¹/₄ - 5/6

First, simplify the mixed fraction part,

E = (17 / 4) - (5 / 6)

Solve the above equation by taking an LCM,

E = ( 102 - 20 ) / 24

E = 41 / 12

E = 3⁵/₁₂

Therefore, the expression after simplification will give the value 3⁵/₁₂.

cause both get the number 22 sooo ya!

Answer:

-2 and 18

Step-by-step explanation:

a + b = 16

ab = -36

a = (16-b)

b(16-b) = -36

16b - b² = -36

-b² + 16b + 36 = 0

b² - 16b - 36 = 0

(b+18)(b-2) = 0

Answer:

5. - 27.02

6. - 18.14

8. - 6.24

Step-by-step explanation:

Hello There!

Because each triangle is a right triangle we can solve for the missing side length using the Pythagorean Theorem

The Pythagorean theorem states that the sum of the two legs squared is equal to the hypotenuse squared

[tex]a^2+b^2=c^2[/tex]

For number 5 we are given two legs so all we have to do is plug in the values

[tex]17^2+21^2=c^2[/tex]

now we solve for c

[tex]17^2=289\\21^2=441\\441+289=730\\c^2=730\\\sqrt{c^2} =c\\\sqrt{730} =27.01851217[/tex]

we're left with c = 27.01851217

are final step is to round to the nearest hundredth

So we can conclude that the missing side length is equal to 27.02

For number 6 we are given the hypotenuse and a leg

So this time we use this equation

[tex]a^2=c^2-b^2[/tex]

where a^2 = missing leg

now we plug in the values and solve for a

[tex]a^2=27^2-20^2\\27^2=729\\20^2=400\\729=329\\a^2=329\\\sqrt{a^2} =a\\\sqrt{329} =18.13835715[/tex]

we're left with a = 18.13835715

our final step is to round to the nearest hundredth

So we can conclude that missing side length is equal to 18.14

For number 8 we are given the hypotenuse and a leg

so once again we use this equation:

[tex]b^2=c^2-a^2[/tex]

now we plug in the values and solve for x

[tex]b^2=8^2-5^2\\8^2=64\\5^2=25\\64-25=39\\b^2=39\\\sqrt{b^2} =b\\\sqrt{39} =6.244997998[/tex]

we're left with b = 6.244997998

our final step is to round to the nearest hundredth

so we can conclude that the missing side length is equal to 6.24

Answer:

C. 3

Step-by-step explanation:

[tex]6 = 2 \times 3 \\ \\ 21 = 3 \times 7 \\ \\ \because \: common \: factor = 3 \\ \\ \therefore \: gcf \: of \: 6 \: and \: 21 = 3[/tex]

Answer:

C. 3

Step-by-step explanation:

Prime Factorization of 6:  2 × 3

Prime Factorization of 21:  3 × 7

Common Factors of 6 and 21: 3

So the greatest common factor of 6 and 21 is 3, that is, GCF of 6 and 21 is 3.
