Answer:

2 a ^2  +  12 a  +  18

Step-by-step explanation:

Substitute the given value into the function and evaluate.

Hope this helps!

A=42

C=90

B=48

We can reason that C will be equal to 90 since it is the right angle. So to find B we have to subtract 90 from 180 to get 90 then subtract 42 to get 48

B=48 degrees

Plug in the values to solve this problem.

Answer:

20 and 77

Step-by-step explanation:

4x-3+x=97

5x-3=97

5x=97+3

5x=100

x=20

Have a NICE day

The larger number is 77 and the smaller number is 20.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, The sum of two numbers is 97.

Assuming the numbers to be a and b.

∴ a + b = 97...(i)

Also given, The larger number is three less than four times the smaller number,

Assuming the larger number to be a, therefore a = 4b - 3...(ii)

Substituting the value of a in eqn(i) we get,

4b - 3 + b = 97.

5b = 100.

b = 20, hence a = 77.

Step-by-step explanation:

Answer:

-83.33 [tex]m/s^2[/tex]

Step-by-step explanation:

Given that:

Initial speed of satellite = 10,000 m/s

Final speed of satellite = 5,000 m/s

Time taken = 1 minute

Let us convert it into seconds.

Time taken = 1 minute = 60 seconds

Let us have a look at the formula:

[tex]v=u+at[/tex]

where [tex]v[/tex] is the final speed

[tex]u[/tex] is the initial speed,

[tex]t[/tex] is the time taken and

[tex]a[/tex] is the acceleration

[tex]5000=10000+a\times 60\\\Rightarrow 60a = 5000-10000\\\Rightarrow 60a = -5000\\\Rightarrow a = -\dfrac{5000}{60}\\\Rightarrow \bold{a = -83.33\ m/s^2}[/tex]

Negative sign indicates that the satellite is in slowing down motion i.e. its speed is decreasing.

So, the answer is:

-83.33 [tex]m/s^2[/tex]

Answer:

thursday

Step-by-step explanation:

Answer:

B: 2800 hydrogen atoms

C: 6760 hydrogen atoms

D: y=amount of oxygen atoms*2

Step-by-step explanation:

B: We know the formula for water is H2O. SO that means that there is 2 hydrogen atoms and 1 oxygen atom. So there is 2 times the amount of hydrogen atoms so we can do 1400*2=2800, So there is 2800 hydrogen atoms in the water.

C: Same thing as B. 3380*2=6760

D: y=amount of oxygen atoms*2. Because there is one oxygen atom and two hydrogen atoms so 1*2=2.

Answer:

Nobody who paid $18 attended, because that can't be part of $60.

Step-by-step explanation:

4 at $15

10 at $20

15 at $25

=

29 people.

There are 30 people was attended the craft demonstration.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

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

for example 4 -2 = 2

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

For example 4*2 = 8

We have been given that number of people attending at respective costs as 5 at $15, 8 at $18, 10 at $20, 15 at $25

Since Sarah spends a total of $60.

As per the condition,

So the number of people who attended the craft demonstration attending at respective costs would be 5 at $15, 10 at $20, and 15 at $25

⇒ 5 + 10 + 15 = 30

Thus, the required number of people would be 30 because $18 can't be included in $60, anyone who paid that amount attended.

Therefore, there are 30 people was attended the craft demonstration.

Answer:

p(10) = - 11

Step-by-step explanation:

To find p(10) substitute n = 10 into the rule, that is

p(10) = - 10 - 1 = - 11

Steps to solve:

P(n) = -n - 1; p(10)

~Substitute

P(10) = -(10) - 1

~Simplify

P(10) = -11

Answer:

35.5 feet

Step-by-step explanation:

x + x + 3 + x + 5 = 99.5

3x + 8 = 99.5

3x = 91.5

x = 30.5

Largest side = (x+5)

30.5 + 5 = 35.5 feet

Answer:

-2 =y

Step-by-step explanation:

-12 = 2 + 5y + 2y

Combine like terms

-12 =2+7y

Subtract 2 from each side

-12-2 = 2+7y-2

-14 = 7y

Divide each side by 7

-14/7 = 7y/7

-2 =y

Answer:

slope = 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

x + 2y = - 16 ( subtract x from both sides )

2y = - x - 16 ( divide all terms by 2 )

y = - [tex]\frac{1}{2}[/tex] x - 8 ← in slope- intercept form

with slope m = - [tex]\frac{1}{2}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{2} }[/tex] = 2
