Answer:
11 dimes and 9 quarters
Step-by-step explanation:
lets make x quarters and y dimes
Here is the equation we have so far:
x+y=20
BUT it can also be used to determine the values:
0.25x+0.10y=3.35
----------------------------------------------------------------------------
0.25x+0.10y=3.35
x+y=20
Im going to solve for quarters first.
Multiply everything by 0.25 on the bottom equation: 0.25x+0.25y=5
Now you have two equations:
0.25x+0.10y=3.35
and 0.25x+0.25y=5
subtract out the 0.25x
.15y=1.65
y=11
------------------------------------------------------------------------------
you have 11 dimes.
x+11=20
x=9
You have 9 quarters

Brenda is selling two different not mixes as snacks. Mix A has 3 oz. of cashews and 7 oz. of almonds. Mix B has 6 oz. of cashews and 5 oz. of almonds. Which inequalities represent the number of mix A mixes, and mix B mixes, B, Brenda can make if she has 72 oz. of cashews and 84 oz. of almonds.
Answer:
Mix A ≤ 12
Mix B ≤ 12
Step-by-step explanation:
Mix A requires 3 oz of cashews and 7 oz of almonds
Mix B requires 6 oz of cashews and 5 oz of almonds
If Brenda makes just Mix A using the available 72 oz of cashews and 84 oz of almonds
With 72 oz of cashews, she would potentially make 72/3=24 Mix A snacks
With 84 oz of almond, she would potentially make 84/7=12 Mix A snacks
Since she would require both cashews and almonds to make Mix A snacks, she would be able to make 12 mix A snacks
Inequality would be:
Mix A ≤ 12
If Brenda makes just Mix B using the available 72 oz of cashews and 84 oz of almonds
With 72 oz of cashews, she would potentially make 72/6=12 Mix B snacks
With 84 oz of almond, she would potentially make 84/5=16 (approximately) Mix B snacks
Since she would require both cashews and almonds to make Mix B snacks, she would be able to make 12 mix B snacks
Inequality would be:
Mix B ≤ 12
Answer:
3A+6B≤72
7A+5B≤84

Step-by-step explanation:
assume that y varies directly as x. If y= -15 when x=5, what is the constant of variation?
Answer:
k = -3
Step-by-step explanation:
Given
Variation: Direct
y = -15 when x = 5
Required
Find the constant of variation
A direct variation is represented as:
y = kx
Where
k = constant of variation
Substitute values for x and y
-15 = k * 5
Multiply both sides by ⅕
⅕ * -15 = k * ⅕ * 5
-3 = k * 1
-3 = k
k = -3
Hence, the constant of variation is -3

How many four digit numbers can be formed using the digits 7, 6, 5 and 2 if
repetitions are allowed?
Answer: The number of four digit numbers can be formed using the digits 7, 6, 5 and 2 = 256
Step-by-step explanation:
Given digits = 7, 6, 5 and 2
If repetition is allowed , we can use Fundamental principal of counting.
By this principal , total four digit numbers can be formed = 4x 4x4 x 4 [∵ choice for each place = 4 ]
= 256
Hence, the number of four digit numbers can be formed using the digits 7, 6, 5 and 2 = 256

A ruler cost x pence a pen costs 10 pence more than the ruler write an expression in terms of x for the cost of the pen
Answer:
(A ruler) = X (a pen) = Y
y = x+10
Step-by-step explanation:
Answer:
A ruler cost x pence.
Let the cost of the ruler be x pencePen costs 10 pence more than the ruler
Therefore, the pen cost (x+10) pence(x+10) is the right answer.the graph is _ throughout its domain and has _ at the x-axis because the value bx can get very close to 0 but never reach it

~Piper Rokelle
Step-by-step explanation:
Pip was thinking of a number. Pip doubles it, then adds 6 to get an answer of 13.8. What was
the original number?
Answer:
The original number is 3.9.
Step-by-step explanation:
With the information given, you can write an expression where the number multiplied for 2 plus 6 is equal to 13.8:
2x+6=13.8, where x is the original number
Now, you can solve for x to find the original number:
2x=13.8-6
x=7.8/2
x=3.9
According to this, the answer is that the original number is 3.9.
A linear function is expressed by a graph of a line that
crosses both axes at the origin. An equation is written in
siope-intercept form to express the same function as
shown in the graph From just this information what
statements can be made?
Choose the true statements
The slope of the equation must be positive.
The y-intercept of the equation is zero.
It is possible that the ine on the graph is horizontal
The slope of the equation must be negative
Answer:
The y-intercept of the equation is zero. It is possible that the line on the graph is horizontal.
Step-by-step explanation:
Answer:
The y-intercept of the equation is zero.
It is possible that the ine on the graph is horizontal
Step-by-step explanation:
The only thing we know for sure is that the function goes through the point (0,0). The line y = 0 passes through (0,0), so it is possible that the line on the graph is horizontal. Since x = 0 where y = 0, the y-intercept is also 0. However, we have no way of knowing for sure what the slope of the equation is.
27.) Find the sum of the length of line segments EF and CD
Answer:
5√10
Step-by-step explanation:
The distance between two points A([tex]x_1,y_1[/tex]) and B([tex]x_2,y_2[/tex]) on the coordinate plane is given by:
[tex]|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2 }[/tex]
From the image attached the coordinates of the points are E(-1, -1), F(8, -4), C(-7, -4) and D(-1, 2).
Hence the lengths of the line segment EF and CD are:
[tex]|EF|=\sqrt{(8-(-1))^2+(-4-(-1))^2} =\sqrt{90}=3\sqrt{10} \\\\CD=\sqrt{(-1-(-7))^2+(-2-(-4))^2}=\sqrt{40} =2\sqrt{10} \\\\Therefore:\\\\|EF|+|CD|=3\sqrt{10} +2\sqrt{10} =5\sqrt{10}[/tex]
What expression has the same value as 27+36
Answer:
its 3x9+13
Step-by-step explanation:
x
The expression 27+36 as be written as: 9(3+12)
What is expression?An expression is a set of terms combined using the operations +, – , x or for example 4 x − 3 or x 2 – x y + 17 .
An equation states that two expressions are equal in value,
for example 4 b − 2 = 6 .
We have: 27+36
Prime factorise both the numbers:
27=3*3*3
36= 2*2*3*3
So,
27+36
=3*3*3+2*2*3*3
= 3*(3*3+2*2*3)
=9(3+12)
Hence, The expression 27+36 as be written as: 9(3+12)
