Answer:
This statement is false. In the expression 11 + 3n, the coefficient is 3.
Step-by-step explanation:
Given
Expression: 11 + 3n
Required
Is 11 the coefficient?
In the given expression, there are two expression;
11 and 3n
Explaining 11
11 is just a constant as it doesn't have any variable attached to it
Explaining 3n
This can be expressed as 3 * n
As such;
[tex]3[/tex] is the coefficient and [tex]n[/tex] is the variable
Hence;
Option A answers the question
Brody’s family took a road trip to the Grand Canyon. Brody fell asleep 65% of the way through the trip. If 35 sleep after they have travel 390 miles, what was the total length of the trip?
Answer:
Total length of the trip = 600 miles
Step-by-step explanation:
Given:
Distance travel during sleep = 65%
Distance travel during sleep = 390 miles
Find:
Total length of the trip
Computation:
Total length of the trip = Distance travel during sleep [100 / 65]
Total length of the trip = 390 [100 / 65]
Total length of the trip = 600 miles

True or False? If false, explain why? All whole numbers are natural numbers.
Answer:It depends, many people do count 0 as a natural number, but MOST do not.
So for most HS text book, the answer is NO, all whole numbers are not natural numbers and the reason is 0 is a whole number but not a natural number.
Answer:
false
Step-by-step explanation:
because the set of whole numbers starts from 0 whereas the set of natural numbers starts from 1 and so on
how long will an object take to travel 4.8km at 48m/s
Answer:
Step-by-step explanation:
time=distance/speed
=4800/48
100
Answer:
[tex]\Huge \boxed{\mathrm{100 \ seconds}}[/tex]
Step-by-step explanation:
4.8 kilometers is 4800 meters.
[tex]\sf \displaystyle time \ (s) = \frac{distance \ (m) }{speed \ (m/s)}[/tex]
[tex]\sf \displaystyle t = \frac{4800}{48}[/tex]
[tex]\sf \displaystyle t = 100[/tex]
It will take the object 100 seconds.
When the sum of a number and 5 is divided by 2, the results is 11. What is the number?
Answer:
17
Step-by-step explanation:
Let x = the number we have to find
From the given information, we have this equation:
(x + 5) / 2 = 11
<=> x + 5 = 11 . 2 = 22
<=> x = 22 - 5 = 17
Answer: 17
Step-by-step explanation:
I guess you would have to guess and check for this one.
17+5= 22
22/2 = 11

Charmaine works mowing lawns and babysitting. She earns $8.80 an hour for mowing and $8.10 an hour for babysitting. How much will she earn for 6 hours of mowing and 1 hour of babysitting?
Answer:
Charmaine earns $60.90 for 6h for mowing and 1h for babysitting.
Step-by-step explanation:
We must write the data problems.
Charmaine = $8.80/h mowing
Charmaine = $8.10/h babysitting
How much will Charmaine earn for 6 h mowing and 1 h babysitting?
1 h mowing ....................... $8.80
6 h mowing ....................... $x
x = 6 h mowing * $8.80
x = $52,8
To find the total earn of Charmaine, we have to gather the earns from mowing and babysitting.
$52,8 (from mowing) + $8.10 (from babysitting) = $60.90

please help asap
will mark brainliest
Answer:
[tex]\pi=\frac{v}{hr^2}[/tex]
Step-by-step explanation:
So we have:
[tex]v=\pi r^2h[/tex]
And we want to solve for π.
First, divide both sides by h:
[tex]\frac{v}{h}=\pi r^2[/tex]
Now, divide both sides again by r²:
[tex]\pi=\frac{v}{hr^2}[/tex]
And this is our answer :)
Answer:
[tex]\frac{v}{r^{2} h} = \pi[/tex]
Step-by-step explanation:
Simply divide both sides by [tex]r^{2}h[/tex] to get pi by itself.

which expression is equivalent to 1.5(6x+3y)+2x-0.05y?
A.11x+4.45y
B.11x+5y
C.11x+2.95y
D.9.5x+4y
Answer:
The correct option is (a).
Step-by-step explanation:
We need to find the expression that is equivalent to 1.5(6x+3y)+2x-0.05y.
Firstly opening brackets as follows :
[tex]1.5(6x+3y)+2x-0.05y=1.5\times 6x+1.5\times 3y+2x-0.05y\\\\=9x+4.5y+2x-0.05y[/tex]
Now taking x terms and y terms together
[tex]9x+4.5y+2x-0.05y=(9x+2x)+(4.5y-0.05y)\\\\=11x+4.45y[/tex]
So, 1.5(6x+3y)+2x-0.05y is equal to 11x+4.45y.
For what value of the variable will the expression 8b−27 be equal to the following:
5
Answer:
We need to find the value of b to make 8b - 27 be equal to 5, so:
8b - 27 = 5
We solve the equation:
8b = 5 + 27
8b = 32
We divide both sides by 8:
b = 32/8 = 4
So now, we know that b=4, and we can verify:
8*4 - 27 = 5
32 - 27 = 5 TRUE

Find p in the equation ( attached photo of the equation)
Answer:
p = - 14
Step-by-step explanation:
Using the rules of exponents
[tex]a^{m}[/tex] ÷ [tex]a^{n}[/tex] = [tex]a^{(m-n)}[/tex]
[tex](a^{m}) ^{n}[/tex] = [tex]a^{mn}[/tex]
Note 81 = 9² and 729 = 9³
Given
[tex](81)^{-4}[/tex] ÷ [tex](729)^{2-p}[/tex]
= [tex](9^{2}) ^{-4}[/tex] ÷ [tex](9^{3}) ^{2-p}[/tex]
= [tex]9^{-8}[/tex] ÷ [tex]9^{6-3p}[/tex]
= [tex]9^{-8-(6-3p)}[/tex]
= [tex]9^{-8-6+3p}[/tex]
= [tex]9^{3p-14}[/tex]
Thus
[tex]9^{3p-14}[/tex] = [tex]9^{4p}[/tex]
Since bases on both sides are equal then equate the exponents
4p = 3p - 14 ( subtract 3p from both sides )
p = - 14

TO FIND: construct 3 equation starting with x=5?
SOLUTION:
The equation is in the form of variable and constant equating.
Let the equation be x=5.
TO CREATE AN EQUATION,
FIRST WE ADD 5 BOTH SIDe,

Step-by-step explanation:
Solve for x:
7 x^25 = 30
Hint: | Divide by an appropriate factor to make the coefficient of x^25 equal to 1.
Divide both sides by 7:
x^25 = 30/7
Hint: | Take 25^th roots of both sides.
Taking 25^th roots gives (30/7)^(1/25) times the 25^th roots of unity:
Answer: x = -(-30/7)^(1/25) or x = (30/7)^(1/25) or x = (-1)^(2/25) (30/7)^(1/25) or x = -(-1)^(3/25) (30/7)^(1/25) or x = (-1)^(4/25) (30/7)^(1/25) or x = -(-1)^(1/5) (30/7)^(1/25) or x = (-1)^(6/25) (30/7)^(1/25) or x = -(-1)^(7/25) (30/7)^(1/25) or x = (-1)^(8/25) (30/7)^(1/25) or x = -(-1)^(9/25) (30/7)^(1/25) or x = (-1)^(2/5) (30/7)^(1/25) or x = -(-1)^(11/25) (30/7)^(1/25) or x = (-1)^(12/25) (30/7)^(1/25) or x = -(-1)^(13/25) (30/7)^(1/25) or x = (-1)^(14/25) (30/7)^(1/25) or x = -(-1)^(3/5) (30/7)^(1/25) or x = (-1)^(16/25) (30/7)^(1/25) or x = -(-1)^(17/25) (30/7)^(1/25) or x = (-1)^(18/25) (30/7)^(1/25) or x = -(-1)^(19/25) (30/7)^(1/25) or x = (-1)^(4/5) (30/7)^(1/25) or x = -(-1)^(21/25) (30/7)^(1/25) or x = (-1)^(22/25) (30/7)^(1/25) or x = -(-1)^(23/25) (30/7)^(1/25) or x = (-1)^(24/25) (30/7)^(1/25)

Step-by-step explanation:
If a and b are the zeroes of the polynomial x2 + 5x + 8, then the value of a2 + b2
is..............(Pls help)
Answer:
9
Step-by-step explanation:
If α and β are the zeros of ax² + bx + c = 0 , then
α + β = [tex]\frac{-b}{a}[/tex] ( sum of zeros ) and
αβ = [tex]\frac{c}{a}[/tex] ( product of zeros )
Given
x² + 5x + 8 = 0
with a = 1, b = 5, c = 8 , with zeros a and b, then
a + b = [tex]\frac{-5}{1}[/tex] = - 5
ab = [tex]\frac{8}{1}[/tex] = 8
Thus
(a + b)² = a² + 2ab + b² , that is
(- 5)² = a² + 2(8) + b²
25 = a² + 16 + b² ( subtract 16 from both sides )
9 = a² + b²
the base of a triangle is 3.4cm.the area is 20.74cm.find the height to 1 dp
Answer:
12.2 cm
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )
Here A = 20.74 and b = 3.4 , thus
[tex]\frac{1}{2}[/tex] × 3.4 × h = 20.74 ( multiply both sides by 2 to clear the fraction )
3.4h = 41.48 ( divide both sides by 3.4 )
h = 12.2 cm
h = 12,2 cm
Step-by-step explanation:Area formula
A = b×h/2
20.74 = 3.4×h/2
41.48 = 3.4h
h = 41.48/3.4
h = 12,2 cm

Which ordered pairs make the open sentence true?
5x- y > 12
Select all the correct answers.
(3, 4)
(4, 9)
(1, – 8)
- (0, – 10)
(-1, – 17
Answer:
(1, -8)
Step-by-step explanation:
5(1) - (-8) = 5 + 8
= 13.
An ordered pair is represented by (x,y). The ordered pair that makes the sentence 5x- y > 12, true is (1,-8)
Given that:
[tex]5x - y > 12[/tex]
First, we test each option
[tex](a)\ (3,4)[/tex]
So, we have:
[tex]5 \times 3 - 4 > 12[/tex]
[tex]15 - 4 > 12[/tex]
[tex]11 > 12[/tex] ---- This is false
[tex](b)\ (4,9)[/tex]
So, we have:
[tex]5 \times 4 - 9 > 12[/tex]
[tex]20 - 9 > 12[/tex]
[tex]11> 12[/tex] --- This is false
[tex](c)\ (1,-8)[/tex]
So, we have:
[tex]5 \times 1 --8 > 12[/tex]
[tex]5 +8 > 12[/tex]
[tex]13 > 12[/tex] --- This is true
[tex](d)\ (0,-10)[/tex]
So, we have:
[tex]5 \times 0--10 > 12[/tex]
[tex]0+10>12[/tex]
[tex]10>12[/tex] ---- This is false
[tex](e)\ (-1,-17)[/tex]
So, we have:
[tex]5 \times -1 --17 > 12[/tex]
[tex]-5 +17 > 12[/tex]
[tex]12 > 12[/tex] --- This is false
Hence, the ordered pair that makes [tex]5x - y > 12[/tex], true is: [tex](c)\ (1,-8)[/tex]
