Answer:
1/4 ; $28.25
Step-by-step explanation:
Given the following :
Cost of stationeries:
Pencil:$1.20
Eraser:$1
Ruler:$0.50
Total : $169.50
Let total Stationeries purchased = t
Fraction of pencils = 1/3t
Remainder = t - 1/3 = 2/3t
Fraction of eraser = 5/8 of remainder
Thus ;
Fraction of eraser = 5/8 * (2/3)t= 10/24 = (5/12)t
Rest were ruler ;
(2/3)t - (5/12)t= (8 - 5)/12
= 3 / 12 = 1/4t
Fraction of rulers = 1/4
Amount spent on erasers:
(5/12) of the total cost of stationery
(5/12) * 169.50 = $70.625
B.) How much more did she spend on erasers than rulers
Amount spent on rulers :
(1/4) * $169.50 = $42.375
Take the difference :
$(70.625 - 42.375) = $28.25
Joey's pizza sells large cheese pizzas for $12.00. Each additional topping costs $0.50. Basketball Boosters bought 12 large pizzas, each with 3 toppings. There are 8 slices per pizza. How much does it cost per slice? Round to the nearest cent.
Answer:
169 cent
Step-by-step explanation:
Given the following :
Cost of large pizza = $12
Cost of additional topping = $0.5
Number of large pizza purchased = 12
topping per large pizza = 3
Amount paid for each pizza :
(cost of pizza) + (3 * cost of topping)
($12) + (3*$0.5)
($12 + $1.5) = $13.5
Total cost of pizza:
Number of pizzas bought * cost per pizza
12 * $13.5 = $162
Number of slices per pizza = 8
Total slices = 12 * 8 = 96 slices of pizza
Cost per slice :
Total cost / total slices
$162 / 96 = $1.6875
= $1.69 = 169 cent

Step-by-step explanation:
i hope this helps
if this helps let me know
Answer:
Step-by-step explanation:
2y + 13 = 5y + 4 { diagonals of a rhombus bisect each other }
by transposing,
2y - 5y = 4 - 13
-3y = -9
both the minus signs get cancelled,
3y = 9
y = 9/3
y = 3
x + 8 = 16 - x { diagonals of a rhombus bisect each other }
again by substituting,
x + x = 16 - 8
2x = 8
x = 8/2
x = 4
∴ x = 4 and y = 3

The formula in cell C5 is "=SUMPRODUCT($A$1:$C$1,A2:C2)". If one copies and pastes the formula from the cell C5 into the cell C6, what numerical value will appear in the cell C6?
Answer:
See Explanation
Step-by-step explanation:
Given
Formula: =SUMPRODUCT($A$1:$C$1,A2:C2)
Required
Determine the numerical value that will appear
The question seem incomplete; however, I'll give a general explanation
FIrst, when the formula is copied from C5 to C6, A2 and C2 changes to A3 and C3 respectively.
This is because they are relative references and they behave on a relative position.
This implies that, when the formula is in cell C5, the formula considers cells A2 and C2 when executing the formula;
However, C6 will consider cells A3 and C3, respectively.

Hi! I'm happy to help!
We can see that A's coordinates currently are -6 for x and 2 for y.
When we move x+3, it moves the x coordinate to the right 3 units. This changes it from -6 to -3. When we move y -2, we move the y coordinate down 2 units. This changes it from 2, to 0.
To sum it up: The final coordinates of A will be -3 for x and 0 for y, also written as (-3,0).
I hope this was helpful, keep learning! :D
Indicate all possible values for the variable in each of the expressions: sqrt(2x+2)+sqrt(6-4x)
Answer:
Given expression:

Alonso estimated the distance across
a river as 1232 meters. What is the
approximate distance across the river to
the nearest thousandth of a meter?
Answer:
1232.000
Step-by-step explanation:
Estimated distance across the river=1,232 meters
Find the approximate distance across the river to
the nearest thousandth of a meter
Note: Thousandth is having 3 values after the decimal point
This means we will round 1,232 meters to the nearest thousandth
1,232 is an whole number and decimal point can only be added at the end like this 1,232.
So we need 3 values after the decimal point.
We must add only values that wouldn't change the original 1,232 meters.
Therefore, zero (0) will be added
1232.000
Is to the nearest thousandth
Reduce 5/15 to its lowest terms
Answer:
The answer is 1/3
Answer:
1/3
Step-by-step explanation:
The factors of 5 are 1,5;
* The factors of 15 are 1,3,5,15.
We can see that the GCD is 5 because it is the largest number by which 5 y 15 can be divided without leaving any residue.
To reduce this fraction, simply divide the numerator and denominator by 5 (the GCF).
So, 5 /15
= 5÷5 /15÷5
= 1 /3
A baker sold apples pies for $10 and blueberry pies for$14. One Saturday they sold a total of 39 pies and collected a total of$458. How many apples pies did they sell and how many blueberry pies did they sell
The total number of apple pies is 22 and the total number of blueberry pies is 17.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that baker sold apples pies for $10 and blueberry pies for$14. One Saturday they sold a total of 39 pies and collected a total of $458.
Asumme the total number of apple pies be 'x' and the total number of blueberry pies be 'y'.
The linear equation that represents the total number of pies is:
x + y = 39
x = 39- y --- (1)
The linear equation that represents the total amount collected is:
10x + 14y = 458--- (2)
Substitute the value of 'x' in equation (2).
10(39- y) + 14y = 458
y = 17
Then Substitute the value of 'y' in the equation (1).
x = 39 - 17
x = 22

(If gets it right get's brainliest)If the hypotenuse of an isosceles right triangle is 14, what is the area of the triangle?
Answer:
49 unit²
Step-by-step explanation:
Right triangle with equal legs given, let the leg be x.
Hypotenuse of isosceles right triangle is
√x² + x² = x√2Area of triangle:
1/2ah= 1/2x²Since we have hypotenuse = 14 units:
x√2=14x= 14/√2Then area:
1/2x² = 1/2*(14/√2)² = 1/2*14²/2 = 7² = 49 unit²Figure A is a scale image of figure B. Figure A maps to figure B with a scale factor of 2/7 What is the value of x?
Answer:
42
Step-by-step explanation:
If the scale factor is 2/7 divide 12 by 2 which is 6. 6 is 1/7 and if Figure a is 7/7
multiply 6 by 7 to get x. That would be 42.
Answer:
42
Step-by-step explanation:
Since the scale factor is [tex]\frac{2}{7}[/tex], we know that the bigger shape went to the smaller shape.
If we know that the smaller shape's side, 12, is [tex]\frac{2}{7}[/tex] of the bigger one, we can make the equation
[tex]\frac{2}{7}x = 12[/tex].
To solve for x, we can divide both sides by [tex]\frac{2}{7}[/tex].
[tex]x = 12\div{\frac{2}{7}}[/tex]
We can multiply by the reciprocal:
[tex]\frac{12}{1} \cdot \frac{7}{2} = \frac{84}{2} = 42[/tex]

you just distribute the numbers to all of the others then simplify.
ex.
(x+4)^2
(x+4)(x+4)
x^2+4x+4x+16
x^2+8x+16
in this, x times x is x^2. then x times 4 is 4x and 4 times x is 4x and 4 times 4 is 16. then combine like terms
4.

A. 2.65, 3
B. 2, –4
C. 2, –10
D. –52, 44
Answer:
x = 2, -4
Step-by-step explanation:
4x^2 + 8x – 32 = 0
Divide by 4
x^2 + 2x – 8 = 0
Add 8 to each side
x^2 + 2x = 8
Take the coefficient of x
2
Divide by 2
2/2 =1
Square it
1^2=1
Add it to each side
x^2+2x+1 = 8+1
(x+1)^2 = 9
Take the square root of each side
sqrt((x+1)^2) = ±sqrt(9)
x+1 = ±3
Subtract 1 from each side
x = -1±3
x = -1+3, -1-3
x = 2, -4
Answer:
B
Step-by-step explanation:
Given
4x² + 8x - 32 = 0 ( divide through by 4 )
x² + 2x - 8 = 0 ( add 8 to both sides )
x² + 2x = 8
To complete the square
add ( half the coefficient of the x- term)² to both sides
x² + 2(1)x + 1 = 8 + 1
(x + 1)² = 9 ( take the square root of both sides )
x + 1 = ± [tex]\sqrt{9}[/tex] = ± 3 ( subtract 1 from both sides )
x = - 1 ± 3
Then
x = - 1 + 3 = 2
x = - 1 - 3 = - 4

Step-by-step explanation:
Answer:
a) 0230 hours
b) 1315 hours
c) 4:05 am
d) 3:25 pm
Step-by-step explanation:
To change a 12 hour clock to a 24 hour clock, note that when it hits p.m., anything over 12 p.m. will have the number added to it.
a) 2:30 am
2:30 am is earlier than 12 pm, therefore, 0230 is your answer. Remember, you must place the 0 in the front to not confuse a user that the 2 is in the tens place value.* *Essentially, use military time:
b) 1:15 pm
1:15 pm is later than 12 pm, therefore, add 12 to the 1 in the hours. Use military time:
0115 + 1200 = 1315
1315 hours is your answer.
To change a 24 hour clock to a 12 hour clock, note the time frame in which the time is given. if over 1200, then subtract by 12, and add the p.m.
0405 = 4:05 am.
1525 = 12 pm + 3:25 = 3:25 pm.
