Answer:

6

Step-by-step explanation:

Richard gets 7 more sweets than Gavin which would probably make Richard have the most so in total he should have around 8 whilst Gavin has 1 so right now we have 4:1:?. Basing off the fact that Richard would have the most sweets Henry would have to have 6 sweets to be able to divide half of it for 3. 4:1:3

Answer:

x=11

Step-by-step explanation:

Answer:

15x^7y^11

Step-by-step explanation:

First, multiply the coefficients 5 and 3 together.  We get:

15x^4y^3 * x^3y^8

Please note that it's mandatory to use " ^ " to indicate exponentiation.

Since x^4*x^3 = x^7, we next obtain:

15x^7y^11

Answer:

Town B

Step-by-step explanation:

Given

See attachment

Required

Which town answers the question

From the attachment, the temperature of town J is -4°C.

This can be represented as:

[tex]J = -4^{\circ}C[/tex]

The opposite of -4 is 4.

So, the town with the temperature that is opposite of -4°C must have a temperature of 4°C.

From the attachment, the temperature of town B is 4°C.

This can be represented as:

[tex]B = 4^{\circ}C[/tex]

Hence, the answer to the question is town B

Answer: b

Step-by-step explanation:

14/17 as a decimal is 0.82352941176

we only need to know what its the hundredths and tenths place so we then just round to thenearest tenth so 2 is less than 5 so 8 stays the same therefor out answer is .8

Step-by-step explanation:

Given:

The probability that Jamil will be late for work is 0.2.

To find:

The probability that Jamil will not be late for work.

Solution:

We have,

P(Jamil will be late) = 0.2

We know that,

P(Jamil will not be late) = 1 - P(Jamil will be late)

                                       = 1 - 0.2

                                       = 0.8

Therefore, the probability that Jamil will not be late for work is 0.8.

Answer:

m=8

hope this helps

have a good day :)

Step-by-step explanation:

2 + 6m +7=57

9+6m=57 add like terms

6m=48 subtract 9 from each side

m=8 divide by 6 on each side

Answer:

M=8

Step-by-step explanation:

First your going to subtract 2 from 7 and thats 5.

then your going to do:

6m+5=57

Then subtract 5 from 57 and thats 52

and divide 52 from 6 and thats 8.

Answer: The reading would be 5.5 on the Richter scale.

Step-by-step explanation:

The intensity of an earthquake that measures 4.5 on the Ritcher scale can be found by solving:

4.5 = log₁₀(x)

for x.

remember that:

logₐ(x) = ln(x)/ln(a)

Then we can rewrite our equation as:

4.5 = ln(x)/ln(10)

4.5*ln(10) = ln(x)

we also know that:

ln(exp(x)) = exp(ln(x)) = x

Then we can apply the exponential equation to both sides to get:

exp( 4.5*ln(10)) = exp( ln(x) ) = x

exp( 4.5*ln(10)) = x

x = 31,622.8

Now, if we have an intensity 10 times larger than this, we will have:

x = 10*31,622.8 = 316,228

The reading on the Richter scale will be:

m = Log₁₀(316,228) = 5.5

Answer:

The second option, B.

[tex](x| -3< x \leq 2)[/tex]

Explanation:

Since the point on -3 is hollow, this means that -3 is not included in the equation. Therefore, -3 < x. Since the point on 2 is filled, this means that 2 is a valid number that is included in the equation. Therefore, [tex]x\leq 2[/tex].

Step-by-step explanation:

Hopefully I'm right,but what you do is add the ones with variables together so

Question 15

so 3a+3a= 6a and 7+2=9

so you have to add the ones that are similar but never add

Answer:

[tex]2\frac{1}{4}[/tex]

Step-by-step explanation:

20 1/4 = 20.25

20.25/9 = 2.25

2.25 = [tex]2\frac{1}{4}[/tex]

Each cake weighs 2.25 pounds.

The weight of each cake will be equal to 2(¹/₄).

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

A mixed expression, also known as a complex fraction, is a fraction that contains a fraction in the numerator, the denominator, or both the numerator and the denominator.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Nine identical cakes weigh a total of 20¼ pounds.

20(¹/₄) = 20.25

20.25/9 = 2.25

2.25 = 2(¹/₄).

Answer:

= 222q^8 - 5m + 20n -37 + 21

Step-by-step explanation:

−5(m−4n−5)−37(p−6q8)−4

step 1  

=(−5)(m)+(−5)(−4n)+(−5)(−5)+(−37)(p)+(−37)(−6q8)+−4

=−5m+20n+25+−37p+222q8+−4

step 2

=−5m+20n+25+−37p+222q8+−4

=(222q8)+(−5m)+(20n)+(−37p)+(25+−4)
