Answer:
53
Step-by-step explanation:
5 choices × 5 choices × 5 choices = 53 possible 3 digit codes including repeats
[tex]\boldsymbol{125}[/tex] unique [tex]3[/tex] digit codes can be created from the [tex]5[/tex] digits.
Number of arrangementsGiven that digits are [tex]=\boldsymbol{\{1,2,3,4,5 \}}[/tex].
Number of digits [tex]=\boldsymbol{5}[/tex]
With repetition" means that repetition is allowed. Thus, in each of the three places, we have five choices.
Therefore,
Number of unique three digit codes can be created from the five digits [tex]=5\times 5\times 5[/tex]
[tex]=\boldsymbol{125}[/tex]
So, [tex]\boldsymbol{125}[/tex] unique [tex]3[/tex] digit codes can be created from the [tex]5[/tex] digits.

Yesterday,grace drove 33 / 1/2 miles.She used 1 and 1/4 gallons of gasoline.What is the unit rate for miles per gallon? (Simplify your answer. Type an integer, fraction, or mixed number.)
Answer:
26 4/5
Step-by-step explanation:
The unit rate for miles per gallon is 26 4/5 gallons
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
The number of miles traveled by Grace = 33 1/2 miles
= 33.5 miles
Amount of gasoline used by Grace = 1 1/4 gallons
= 1.25 gallons
Now ,
The unit rate for miles per gallon is calculated as
The unit rate for miles per gallon =
Number of miles traveled by Grace / Amount of gasoline used by Grace
The unit rate for miles per gallon = 33.5 / 1.25
= 26.8 miles per gallon
Therefore , the unit rate for miles per gallon is 26.8 or 26 4/5 miles per gallon
Hence , the unit rate for miles per gallon is 26 4/5 miles per gallon

Can someone help me!!
Answer:
Its not clear what form to write this equation in but the relationship is that 3 cubes are added from figure to figure. The best equation i can think off would be y=x+3. This is because the new figure, y, is equal to the figure before it plus 3
y=x+3 is the best answer in this case

long
Answer:
Option (D)
Step-by-step explanation:
Sue made a quilt pattern comprising 16 congruent isosceles right triangles.
She cuts the pieces of triangle having each leg = 6 inches
By applying Pythagoras theorem in isosceles triangle,
(Hypotenuse)² = (leg 1)² + (leg 2)²
x² = 6² + 6²
x² = 72
x = √72
x = 8.485
x ≈ 8.5

There are 500 sheets in a pack of paper. 500 sheets of paper weigh 2.5kg.
Work out the weight of 50 sheets of paper.
Answer:
It's a proportion:
500=2.5
50=x
2.5×50:500=0.25kg
50 sheets weigh 0.25 kg
Step-by-step explanation:
Answer:
0.25
Step-by-step explanation:
the weight of a sheet = 2.5kg/500
the weight of a sheet = 0.005kg
the weight of 50 sheets = 0.005 * 50
the weight of 50 sheets = 0.25kg
ORsince it's a uniform rate
500 sheets = 2.5kg
50 sheets = xkg
then you cross multiply.Having:
500*x = 2.5 * 50
500x = 125
then x = 125/500
x = 0.25
Two ships set sail in different directions from the same place. Tyler's ship sail 35 miles while Noah's ship sails for 42 miles. At the same time they are 56 miles apart. What was the angle between their paths when they started?
Answer:
The angle between their paths when they started is 93°.
Step-by-step explanation:
The Law of Cosines
It relates the length of the sides of a triangle with one of its internal angles.
Let a,b, and c be the length of the sides of a given triangle, and x the included angle between sides a and b, then the following relation applies:
[tex]c^2=a^2+b^2-2ab\cos x[/tex]
When the two ships travel in different directions from the same point in the plane, they form an angle we called x in the image below.
Tyler's ship sails a=35 miles and Noah's ship sails for b=42 miles. At some time they are c=56 miles apart.
Since we know the values of all three side lengths, we solve the equation for x:
[tex]\displaystyle \cos x=\frac{a^2+b^2-c^2}{2ab}[/tex]
Substituting values:
[tex]\displaystyle \cos x=\frac{35^2+42^2-56^2}{2(35)(42)}[/tex]
Calculating:
[tex]\displaystyle \cos x=-\frac{147}{2940}=-\frac{1}{20}[/tex]
Computing the inverse cosine:
[tex]x = \arccos(-0.05)[/tex]
[tex]x \approx 93^\circ[/tex]
The angle between their paths when they started is 93°.

From the information given, can you prove that the triangles congruent using SAS congruent postulate? If not, what do you need to know to make the triangle congruent using the SAS congruence postulate?
Answer:
D.
Step-by-step explanation:
to prove congruency of two triangles, you need two congruent sides and one congruent angle
in this case we are given exactly that, 2 sides and one angle that is congruent
we would also need to make sure that the given sides and angles are actually congruent, and not mismatched
we can do this by looking at the positions of the letters in each congruency statement
for example, the letters LO and MA are the first two letters in each triangle's name, this means that they are congruent and properly matched
if you do this with every statement that you are give, you can see that the triangles can be proven by SAS

Solve. 7w - 12 = 44 w = *
Answer:
[tex] \huge{ \boxed{ \bold{ \text{w = \: 8}}}}[/tex]
☃ Question : Solve for w[tex] \text{7w - 12 = 44 }[/tex]
✎ Step by step explanation[tex] \text{7w - 12 = 44}[/tex]
Move 12 to right hand side and change it's sign
[tex] \longrightarrow{ \sf{7w = 44 + 12}}[/tex]
Add the numbers : 44 and 12
[tex] \longrightarrow{ \sf{7w = 56}}[/tex]
Divide both sides by 7
[tex] \longrightarrow{ \sf{ \frac{7w}{7} = \frac{56}{7}}} [/tex]
[tex] \longrightarrow{ \boxed{ \bold{ \red{ \sf{w = 8}}}}}[/tex]
--------------------------------------------------------------------
☟ Let's check whether the value of w is 8 or not !
✑ Verification :L.H.S ( Left hand side ) :
[tex] \dashrightarrow{ \sf{7w - 12}}[/tex]
plug the value of w and simplify
[tex] \dashrightarrow{ \sf{7 \times 8 - 12}}[/tex]
[tex] \dashrightarrow{ \sf{56 - 12}}[/tex]
[tex] \dashrightarrow{ \sf{ 44}}[/tex]
R.H.S ( Right Hand Side ) = 44
L.H.S = R.H.S ( Hence , the value of w is 8 ).

What are the solutions of the equation (2x + 3)2 + 8(2x + 3) + 11 = 0? Use u substitution and the quadratic formula to
solve.
Answer:
x= −41 /20
Step-by-step explanation:
(2x+3)(2)+8(2x+3)+11=0
(4x+16x)+(6+24+11)=0(Combine Like Terms)
20x+41=0
20x+41=0
Step 2: Subtract 41 from both sides.
20x+41−41=0−41
20x=−41
Step 3: Divide both sides by 20.
20x /20 = −41 /20
x= −41 /20
