Which expression has the same value as the one below? 87 + (-12)

Answer:

13

Step-by-step explanation:

42 - (32 + 4) + 7 =

42 - 36 + 7 =

13

Answer:

15.

Step-by-step explanation:

Since 32 + 4 are in parenthesis, you'd do that first. 32 plus 4 equals 36, which subtracted from 42 is equal to 8. 8 plus 7 is 15. Therefore, your answer is 15.

I hope this helped, have a nice day.

Answer:

28

Step-by-step explanation:

Since this is a right triangle, we can use the pythagorean theorem

a^2 +b^2 = c^2  where a and b are the legs and c is the hypotenuse

a^2 + 45^2 = 53^2

a^2 +2025=2809

a^2 = 2809-2025

a^2 =784

Take the square root of each side

sqrt(a^2) = sqrt(784)

a =28

Answer:

15 cubes

Step-by-step explanation:

The volume of a rectangular prism is given as :

V = Lenght * width * height

V = 3/2 * 5/2 * 1/2

V = 15 / 8 cm³

Volume of a cube = a³

Where, a = side length of cube

a = 1/2 cm

V = a³ = (1/2)³ = (1/2 * 1/2 * 1/2) = 1/8

Volume of pyramid / volume of cube

15 / 8 ÷ 1 / 8

15 / 8 * 8 / 1

= 15

Answer:

[tex]\frac{5}{8}[/tex]

Step-by-step explanation:

Hi there!

We're given that there are 8 marbles in total. 2 marbles are yellow and 3 are red, making the number of red AND yellow marbles 5 (2+3=5)

Because 5 out of the 8 marbles are yellow or red, the probability of choosing one of them is [tex]\frac{5}{8}[/tex].

I hope this helps!

Answer:

P(Red or Yellow) = 5/8

Step-by-step explanation:

2 (yellow) + 3 (red) = 5

Hence, the probability is 5/8

Answer: 1,152 notebooks

Step-by-step explanation:

You just do 144 x 8. I’m not really sure what they mean when they say use breaking apart method. Maybe break them up into 8 group of 144. Then just add 144 together 8 times instead of multiplying hope this helps. :)

Hello! answer: 175 cm2

Step-by-step explanation:

9 × 7 = 63 63 ÷ 2 = 31.5 31.5 × 4 = 126

7 × 7 = 49 126 + 49 = 175 therefore the area is 175 Hope that helps! And I believe the unuts would be cm2 but don't quote me on it

Answer:

Step-by-step explanation:

radius=diameter/2

=9/2

=4.5

Answer:

4.5

Step-by-step explanation:

9= diameter and Radius= diameter divided by 2

9 divided by 2 = 4.5

Answer:

8x+20

36

Step-by-step explanation:

4(2x) + 4(5)

= 8x +20

Hence,

Substituting 2 into 8x+20:

8(2)+20

= 36

Answer:

69g/cm is 6.9kg/m

Step-by-step explanation:

[tex]1 g --> \frac{1}{1000}kg\\\\69g --> \frac{69}{1000}kg\\\\1cm --> \frac{1}{100}m\\\\\frac{69 g}{1cm} = \frac{\frac{69}{1000} }{\frac {1}{100}} = \frac{69}{1000} \times \frac{100}{1} = \frac{69}{10} = 6.9kg/m[/tex]

Answer:

[tex]69 \: g {cm}^{ - 1} \\ 69 \times {10}^{ - 3} \times ({10}^{ - 2} ) ^{ - 1} kg \: {m}^{ - 1} \\ 69 \times {10}^{ - 1} \: kg {m}^{ - 1} \\ 6.9 \: kg {m}^{ - 1} [/tex]

Answer:

the height is 6 units

Step-by-step explanation:

Given that

The area of the parallelogram is 54 units squared

The base is 9 units

We need to find out the height

As we know that

The area of the parallelogram = Base × height

54 =  9 × height

So, the height is

= 54 ÷ 9

= 6 units

Hence, the height is 6 units

Answer:

You can only find the height if you know the length.

Answer:

[tex](a)\ \{SSS\}[/tex]

[tex](b)\ \{FSSS\}[/tex]

[tex](c)\ \{FFSSS, SFSSS\}[/tex]

[tex](d)\ \{FFFSSS, SSFSSS, SFFSSS, FSFSSS\}[/tex]

[tex](e)\ \{FFFFSSS, FFSFSSS, FSSFSSS, SSFFSSS, SFSFSSS, SFFFSSS, FSFFSSS\}[/tex]

Step-by-step explanation:

Given

[tex]S\to[/tex] Success

[tex]F\to[/tex] Failure

[tex]n \to 3[/tex] Consecutive trials until S happens

[tex]Y \to[/tex] Number of trials

For every possible outcome, the last 3 must be SSS. So, we have:

[tex](a)\ Y = 3[/tex]

The only possibility here is: [tex]\{SSS\}[/tex]

because 3 trials implies that all outcomes must be S.

[tex](b)\ Y = 4[/tex]

The only possibility here is:

[tex]\{FSSS\}[/tex]

because 4 trials implies that the first outcome must be F

[tex](c)\ Y = 5[/tex]

The possibilities are:

[tex]\{FFSSS, SFSSS\}[/tex]

because 5 trials implies that the first and the second outcomes must be FS or SF.

[tex](d)\ Y = 6[/tex]

The possibilities are:

[tex]\{FFFSSS, SSFSSS, SFFSSS, FSFSSS\}[/tex]

because 6 trials implies that the first three outcomes are: FFF, SSF and SFF

[tex](e)\ Y = 7[/tex]

The possibilities are:

[tex]\{FFFFSSS, FFSFSSS, FSSFSSS, SSFFSSS, SFSFSSS, SFFFSSS, FSFFSSS\}[/tex]

because 7 trials implies that the first three outcomes are: FFFF, FSSF and SSFF and FFSF (similar to (e))

Answer:

29.2 metres squared

Step-by-step explanation:

because 3 decimetre equal 1 metre, 7 metres and 3 decimetre equal 7.3 metres.

now we just use the area formula to solve.

Area = Length × Width = 7.3 × 4 = 29.2 metres squared

Answer:

7.43

hope this helps

have a good day :)

Step-by-step explanation:

Answer:

7.43

Step-by-step explanation:

So lets go over a few things:

In decimal form, you start of in the tenths.

So in this case that is 4.

After tenths, is hundreths, thousandths, ten thousandths, etc.

Since hundreths comes after the tenths, that will be 2.

Any number 5 or greater will be rounded up, and any number below 5 is rounde down.

Now, to find if we raise or lower the hundreths(which is 2), we must see if the thousandth splace is above or lower than 5.

We can see that our thousandths is 8.

Since 8 is higher than 5, the 2 in our hundreths place will go up to 3.

So we get:

7.43

Hope this helps!
