Jodie works at the local candy store and sells candy by the pound. She
sells 2½ pounds of gumdrops, 3 pounds of orange slices, and
¾ pounds of gummi bears. How much candy did Jodie sell altogether?
Answer:
6.25 or 6 1/4
Step-by-step explanation:
Jodie sold 6.25 candy altogether.
What is the fraction?A fraction is defined as a numerical representation of a part of a whole that represents a rational number.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
The operator that perform the arithmetic operations are called arithmetic operators.
Operators which let do basic mathematical calculation
+ Addition operation : Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation : Subtracts right hand operand from left hand operand.
For example 4 -2 = 2
* Multiplication operation : Multiplies values on either side of the operator
For example 4*2 = 8
Given that
Jodie sells 2½ pounds of gumdrops,
3 pounds of orange slices, and ¾ pounds of gummi bears.
Convert the fractions into decimals
Number of pounds of gumdrops = 2½ = 5/2 = 2.5
Number of pounds of gummi bears = ¾ = 0.75
So the total amount of candy Jodie sold :
⇒ 2.5 + 3 + 0.75
⇒ 6.25
Hence, Jodie sold 6.25 candy altogether.

Brad places a marker on the ground 10 ft. away from the base of a tree at a botanical garden. He walks back towards the tree until he is standing 4 ft. away from the marker, and he is 6 ft. tall. Assuming that the top of Brad's head, the top of the tree, and the marker form two simliar triangles, how tall is the tree
Answer:
15ft
Step-by-step explanation:
Calculation for how tall is the tree
First step Let the proportion be x/10ft = 6ft /4ft
Second step is to cross-multiply by 4x
4x =10ft*6ft
4x = 60
Third step is to divide both sides by 4
4x = 60
4x/4=60/4
x=15 ft
Therefore the tree will be 15ft tall
how to solve using Substitution or Elimination??? Help!!!
y=3x-1
y=2x+2
Answer:
x=3
y=8
Step-by-step explanation:
the given equations are y=3x-1 --------(1)
and y=2x+2---------(2)
Using substitution method,
and solving y=3x-1
y+1=3x
or y+1/3 =x ------(3)
Putting the value of x= y + 1 / 3 in equation 2
y= 2x+2
or, y = 2 ( y + 1/3) +2
or, y= 2y + 2 / 3 +2
or, y = 2y + 2 + 6 // 3 ( Taking LCM)
Or, 3 y = 2y + 2 + 6 ( the denominator gets multiplied to y)
OR, 3 Y - 2Y =6 PLUS 2
or y = 8
therefore, y=8
now substituting the value of y=8 in equation (3)
y + 1 /3 = x
or ,,, 8 plus 1 by 3 =x
or,,,,, 9 by 3 =x
Therefore, x is 3

If a1=2 and an=2an-1 find the first 5 sequences
Answer:
The first 5 terms of the sequence are 2, 4, 8, 16 and 32.
Step-by-step explanation:
Given:
[tex]a_{1}[/tex] = 2
[tex]a_{n}[/tex] = 2[tex]a_{n-1}[/tex] -----------------(i)
To get the first 5 terms of the sequence, substitute in turn, n = 1, 2, 3, 4, 5 into equation (i).
The first term (when n = 1) has been given as:
[tex]a_{1}[/tex] = 2
The second term (when n = 2) is given as:
[tex]a_{2}[/tex] = 2[tex]a_{2-1}[/tex]
[tex]a_{2}[/tex] = 2[tex]a_{1}[/tex] (but [tex]a_{1}[/tex] = 2 )
=> [tex]a_{2}[/tex] = 2(2)
=> [tex]a_{2}[/tex] = 4
The third term (when n = 3) is given as:
[tex]a_{3}[/tex] = 2[tex]a_{3-1}[/tex]
[tex]a_{3}[/tex] = 2[tex]a_{2}[/tex] (but [tex]a_{2}[/tex] = 4 )
=> [tex]a_{3}[/tex] = 2(4)
=> [tex]a_{3}[/tex] = 8
The fourth term (when n = 4) is given as:
[tex]a_{4}[/tex] = 2[tex]a_{4-1}[/tex]
[tex]a_{4}[/tex] = 2[tex]a_{3}[/tex] (but [tex]a_{3}[/tex] = 8 )
=> [tex]a_{4}[/tex] = 2(8)
=> [tex]a_{4}[/tex] = 16
The fifth term (when n = 5) is given as:
[tex]a_{5}[/tex] = 2[tex]a_{5-1}[/tex]
[tex]a_{5}[/tex] = 2[tex]a_{4}[/tex] (but [tex]a_{4}[/tex] = 16 )
=> [tex]a_{5}[/tex] = 2(16)
=> [tex]a_{5}[/tex] = 32
Therefore, the first 5 terms of the sequence are 2, 4, 8, 16 and 32.
Boris had 91.5 g of pepper then he use 0.4 g of the pepper to make each plate of scrambled eggs how much pepper does Boris have left if he made 16 plates of scrambled eggs
Answer:
85.1 g
Step-by-step explanation:
Boris has 91.5 g of pepper
He used 0.4g to make one plate of scrambled egg
If she made 16 plates of scrambled egg then the amount of pepper that will be left can be calculated as follows
= 0.4×16
= 6.4g
= 91.5g - 6.4g
= 85.1g
Hence Boris will have 85.1g of pepper left
At the movie theatre, child admission is $5.10 and adult admission is $8.80. On Saturday, 157 tickets were sold for a total sales of $1144.80. How many child tickets were sold that day?
Answer:
64 child tickets
Step-by-step explanation:
Let's set this up a system of equations. Number child tickets is c and adults are a.
5.1c+8.8a=1144.8
c+a=157
We can now solve by elimination. Let's multiply the second equation by -8.8 so that we are left with the child tickets.
-8.8c-8.8a= -1,381.6
We combine the two equations.
-3.7c=-236.8
Divide both sides by -3.7
c=64

Darrell bought an 80 pound bag of dog food. If ⅝ of a pound are used to
feed the dog each day, how many days will the bag of dog food last?
Answer:
The 80 p0und bag will last 128 days.
Step-by-step explanation:
In order to find out how much days the 80 pound bag last we have to divide the 80 pounds by the among that the dog eats each day. And so we get.....
80 / [tex]\frac{5}{8}[/tex] = [tex]\frac{80}{1} / \frac{5}{8}[/tex] = [tex](\frac{80}{1})(\frac{8}{5})[/tex] = [tex]\frac{640}{5}[/tex] = 128
Answer:
For some reason my answer got deleted.
The dog food will last 128 days,
Step-by-step explanation:
80 ÷ 5/8 = 128

Răspuns:
318 de participanți
Explicație pas cu pas:
Dat fiind:
Număr în parc = 106
Numărul din parc reprezintă 1/3 din numărul elevilor care participă la activitatea de curățenie.
Pentru a obține numărul total de studenți care participă la activitate; fie numărul total = x
Prin urmare;
1/3 din x = 106
x / 3 = 106
Înmulțiți ambele părți cu 3
x = 318
Prin urmare, numărul total de studenți implicați în activitatea de curățenie = 318 stuaen

Ms. Blankenship had $80 to purchase school supplies for her class. She bought 32 glue sticks and 32 boxes of crayons. Each glue stick costs $1.40, and each box of crayons costs $0.59. How much money did Ms. Blankenship have left after these purchases?
Answer:
$16.32
Step-by-step explanation:
First you need to find how much each thing is going to cost.
So for 32 glue sticks, it will cost $44.80 because you multiply 32 by 1.40.
Next you need to find the cost of thebox of crayons, which is $18.88 because you multiply 32 by 0.59.
Then you add those two totals together and you get 63.68.
Lastly you subtract that from 80 to see how much money Ms. Blankenship has leftover which is $16.32.
Hope this helps. :)
Different observers reporting different conclusions when watching the same event may indicate unreliability in what type of data collection
Answer:
Personal observation.
Step-by-step explanation:
Worthy of note is to say that, it's is practically impossible to have a line of different people retell what they heard, saw or experienced in the same way. Because of the fact that human being differs, there's always a difference in the retelling of the story eventually. Everyone seems to retell the story in a manner they can relate to, in a manner of what they understand, and that's given rise to unreliability in personal observation. Not that they're wrong, nor that one is right than the other, but that they're just not reliable.

Solution of the given equation 2x+8=4x-10 is x=9.
Solution of an equation are the values to the unknown variables that makes the equality in the equation true
Given equation is :
2x+8=4x-10, consider it as equation (1)
To solve this equation firstly, we isolate the terms which contain x in the LHS and the constant terms in RHS.
Then, the equation will become:
2x-4x = -10-8
Solving the LHS and RHS:
-2x = -18
Divide both the sides by -2, we get:
x = -18/(-2)
x = 9
That means x=9 satisfies the given equation.
Hence, x=9 is the solution of the given equation.
