Step-by-step explanation:
9/81= kg per book= 1/9 kg
88 books weigh 1/9*88=88/9 kg = 9.77 kg
Answer:
9.77777777768kg
Step-by-step explanation:
81 books= 9kg
so, one book= 9/81= 0.11111111111111
Therefore, 88 books(88x0.1111111)
Answer: 9.77777777768kg

what is the least common denominator of 9/10 and 1/4
Answer:
Step-by-step explanation:
Solution:
Rewriting input as fractions if necessary:
9/10, 1/4
For the denominators (10, 4) the least common multiple (LCM) is 20.
LCM(10, 4)
Therefore, the least common denominator (LCD) is 20.
Calculations to rewrite the original inputs as equivalent fractions with the LCD:
9/10 = 9/10 × 2/2 = 18/20
1/4 = 1/4 × 5/5 = 5/20

Factor 8m^6 - 64n^12p^15. don't waste points and show steps and factors. please
Answer:
8(m⁶ - 8n¹²p¹⁵)
Step-by-step explanation:
Given:
8m⁶ - 64n¹²p¹⁵
The only part that we can factor out is in the coefficients. Because both terms use different variables, they can not be factored. However, both terms are divisible by eight, so we can say it equals:
8(m⁶ - 8n¹²p¹⁵)
And that is all the factoring that can be done.
Use Substitution to solve the following System of Equations.
y=-22 - 4
y = 4x + 2
Oh
Answer:
X=4
Y=18
I think
Answer:
(- 1, - 2 )
Step-by-step explanation:
Given the 2 equations
y = - 2x - 4 → (1)
y = 4x + 2 → (2)
Substitute y = 4x + 2 into (1)
4x + 2 = - 2x - 4 ( add 2x to both sides )
6x + 2 = - 4 ( subtract 2 from both sides )
6x = - 6 ( divide both sides by 6 )
x = - 1
Substitute x = - 1 into either of the 2 equations and solve for y
Substituting into (2)
y = 4(- 1) + 2 = - 4 + 2 = - 2
solution is (- 1, - 2 )
Rewrite the equation by completing the square.

There is a parallelogram ABCD with diagonals AC and BD. The diagonals AC and BD intersects each other at point E. Side AB is congruent to side CD. If ∠BAC ≅ ∠DCA, the Choose... theorem can be used to show that △ABE ≅ △CDE.
Answer:
SAS theorem
Step-by-step explanation:
Given
[tex]\square ABCD[/tex]
[tex]\[ \lvert \[ \lvert AB =\[ \lvert \[ \lvert CD[/tex]
[tex]\angle BAC = \angle DCA[/tex]
Required
Which theorem shows △ABE ≅ △CDE.
From the question, we understand that:
AC and BD intersects at E.
This implies that:
[tex]\[ \lvert \[ \lvert AE = \[ \lvert \[ \lvert EC[/tex]
and
[tex]\[ \lvert \[ \lvert BE = \[ \lvert \[ \lvert ED[/tex]
So, the congruent sides and angles of △ABE and △CDE are:
[tex]\[ \lvert \[ \lvert AB =\[ \lvert \[ \lvert CD[/tex] ---- S
[tex]\angle BAC = \angle DCA[/tex] ---- A
[tex]\[ \lvert \[ \lvert BE = \[ \lvert \[ \lvert ED[/tex] or [tex]\[ \lvert \[ \lvert AE = \[ \lvert \[ \lvert EC[/tex] --- S
Hence, the theorem that compares both triangles is the SAS theorem
What is the inverse operation do use to solve for t?
t - 19=2
We use addition, or rather the addition property of equality.
t-19+19=2+19
t=21
:D
Step-by-step explanation:
Addition is the inverse operation.
inverses:
addition/subtraction
multiplication/ division
If you need to solve for t:
t-19=2
add 19 to both sides to isolate the variable (t)
t=21

Step-by-step explanation:
Max typically drinks 3 3/4 cups of milk each day. Today he tripled that amount.
How much milk did Max drink today?
Answer:
11 1/4
Step-by-step explanation:
Multiply this by three, 3, 6, 9.
3/4, 1 2/4, 2 1/4.
2 + 9 = 11.
11= 1/4 = 11 1/4
Answer:
Max drank 11 1/4 cups of milk today.
Explanation:
Convert the mixed number (3 3/4) to a fraction.
Then your equation becomes:
15/4 x 3/1 (since he tripled the cups of milk he drank you multiply by 3 which as a fraction is 3/1)
Next:
15/4 x 3/1= 11 1/4!
Hope this helps :)
Is -17/-40 equal to -0.425? Show your work.
plz help
Answer:
yes because if you simplify 17/40 to a decimal it will give you 0.425 and then add the negative signs and you get -0.425 so yes they are equal

The outside diameter (od) of a pipe is 4 9/32 inches. The walls are 7/32 inches thick. find the inside diameter.
Please explain how you got your answer.
The inside diameter would be the outside diameter minus 2 of the wall thicknesses.
4 9/32 - (2 x 7/32)
Simplify:
4 9/32 - 14/32
Because 14/32 is larger than 9/32 change one of the hole numbers to a fraction: 1 = 32/32
rewrite 4 9/32 as 3 41/32
Now subtract:
3 41/32 - 14/32 = 3 27/32 inside diameter.

Option (2)
Step-by-step explanation:
Amount of apples in a box = [tex]2\frac{3}{4}[/tex] pounds
= [tex]\frac{11}{4}[/tex] pounds
Apples used by Sage = [tex]\frac{1}{5}th[/tex] Part of the total amount
= [tex]\frac{1}{5}[/tex]th part of the apples in the box
= [tex]\frac{1}{5}\times \frac{11}{4}[/tex]
= [tex]\frac{11}{20}[/tex] pounds
Therefore, Sage used [tex]\frac{11}{20}[/tex] pounds of the apples.
Option (2) will be the answer.
What is the correct inverse function for f(x)=In(3x)?
Answer:
f⁻¹(x) = eˣ / 3
Step-by-step explanation:
f(x) = In(3x)
y = In(3x)
swap x and y: x = In(3y)
solve y: eˣ = 3y
y = eˣ / 3
f⁻¹(x) = eˣ / 3

Simplify the expression using the order of operations. The nature park has a pride of 4 lions and 8 cubs. The adults eat 7 pounds of meat each day and the cubs eat 4 pounds. Simplify 4 × 7 + 8 × 4 to find the amount of meat consumed each day by the lions. The lions consume pounds of meat each day.
Answer:
60 pounds of meat
Step-by-step explanation:
Number of lions = 4
Pounds of meat consumed = 7 pounds each
Number of cubs = 8
Pounds e meat consumed = 4 pounds each
Amount of meat consumed each day by the lions = 4 × 7 + 8 × 4
Multiply first
= 28 + 32
= 60 pounds of meat
The lions consume 60 pounds of meat each day.

The area of a trapezoid is 46 square yards. If the height is 4 yards and the length of one of the bases is 16 yards,determine the length of the other base
Answer: 7 yards
Step-by-step explanation:
Given
The area of the trapezoid is [tex]46\ yards^2[/tex]
The height of the trapezoid is [tex]h=4\ yards[/tex]
One of the bases is [tex]a=16\ yards[/tex]
Suppose another base is b
The area of the trapezoid is
[tex]A=\dfrac{a+b}{2}\times h[/tex]
Putting values
[tex]\Rightarrow 46=\dfrac{16+b}{2}\times 4\\\\\Rightarrow 23=16+b\\\Rightarrow b=7\ yards[/tex]
The length of other base is 7 yards

Which quadratic function has a vertex point of (3,5) and passes through the
point (-2,55)?
9514 1404 393
Answer:
f(x) = 2(x -3)² +5
Step-by-step explanation:
For vertex (h, k) and scale factor 'a', the vertex form is ...
f(x) = a(x -h)² +k
We can fill in the values of h and k from your vertex, and use the values of the extra point to find 'a'.
55 = a(-2 -3)² +5
50 = 25a . . . . . . . . subtract 5
a = 2 . . . . . . . . . . . divide by 25
So, the function is ...
f(x) = 2(x -3)² +5
__
In standard form, that will be ...
f(x) = 2x² -12x +23
