Answer:

You have 12 quarters and 30 dimes.

Step-by-step explanation:

If you have an equation that says 10d+25q= 600 cents (d meaning dime and q meaning quarter) and have another equation that says d+w=42, then you could use those two equations to solve the problem.

Hope this helps a little bit. It is a little hard to explain but let me know if you need some more help.

Answer:

-8

Step-by-step explanation:

Vertex of function f(x)

From inspection of the graph, the vertex of f(x) is (2, 1)

Vertex of function g(x)

Given:  [tex]g(x)=2x^2-8x+1[/tex]

Standard form of a parabola is [tex]y=ax^2+bx+c[/tex]

Vertex form of a parabola is [tex]y=a(x-h)^2+k[/tex]
(where (h, k) is the vertex)

To convert from standard to vertex form, complete the square.

Set the equation to zero:

[tex]\implies 2x^2-8x+1=0[/tex]

Add 7 to both sides:

[tex]\implies 2x^2-8x+8=7[/tex]

Factor out common term 2 on left side:

[tex]\implies 2(x^2-4x+4)=7[/tex]

Factor expression inside brackets:

[tex]\implies 2(x-2)^2=7[/tex]

Subtract 7 from both sides:

[tex]\implies 2(x-2)^2-7=0[/tex]

Therefore:

[tex]g(x)=2(x-2)^2-7[/tex]

So the vertex of g(x) is (2, -7)

Solution

y-value of the vertex of f(x) = 1

y-value of the vertex of g(x) = -7

y-value of vertex of f(x) subtracted from the y-value of the vertex of g(x):

-7 - 1 = -8

Step-by-step explanation:

Answer:

Sin theta= a/c

= 5/7.8

= 0.64

= 1

Step-by-step explanation:

Lets find the hypotenuse first by applying Pythagorean theorem.

a^2+b^2=c^2

(6)^2+(5)^2=c^2

36+25=c^2

61=c^2 (FIND SQUARE ROOT)

7.8=c

Sin theta= a/c

= 5/7.8

= 0.64

= 1

Cos theta= b/c

= 6/7.8

Tan theta= a/b

= 5/6

Answer:

6 weeks

Step-by-step explanation:

Let x represent the weeks

[tex]25=10+ (10x-7.5x = 2.5)[/tex]

[tex]25-10=2.5x = 15[/tex]

[tex]\frac{15}{2.5}=x \\(150/25)\\x=6[/tex]

Carol and Cathy will have same saved amount after 6 weeks.

What do you mean by algebraic expressions ?

Algebraic expression is an equation which consists of variables and the arithmetic operations such as division , multiplication , etc.

It is given that Carol started with $25 and saved per week an amount of $7.50 whereas Cathy started with $10 and saved per week amount of $10.

Let's assume that after x no. of weeks they will have same saved amount.

So , we can write an algebraic expression which is :

25 + (7.5 × x) = 10 + (10 × x)

Now , reordering the like terms we get :

10x - 7.5 x = 25 - 10

Simplifying this we get :

2.5 x = 15

or

x = 15 ÷2.5

or

x = 6 weeks

Therefore , Carol and Cathy will have same saved amount after 6 weeks.

Answer:

5xy/27

Step-by-step explanation:

The product of the two numbers x and y = xy

Five times the product of the two numbers x and y = 5xy

then,

divided by a third number 27 = 5xy/27

The expression will be : 5xy/27

Answer:

13

Step-by-step explanation:

2 hours = 4 inches

2/2 equals 1 hour

4/2 equals 2 inches

2 inches of snow per hour

6.5*2 is 13

you should expect 13 inches of snow in 6.5 hours

Answer:

Step-by-step explanation:

Distance formula:

d = rt

where d = distance, r = average speed and t = time travelled.

They told us that an object travels 30 meters in 20 seconds.

So we can say d = 30 and t = 20

If you put these values back into the distance formula you get:

d = rt

30 = r times 20

30 = 20 r

So now we want to find what "r" (average speed) is.

Divide both sides by 20.

20 r = 30

r =  [tex]\frac{30}{20}[/tex] = 1.5 meters per second.

Answer:

Three arithmetic means between -16 and 4 are : 20 , 10 and  [tex]\frac{20}{3}[/tex]

Step-by-step explanation:

we have to find out three arithmetic means between -16 and 4

-16 , ____  , ____ , ____ 4

so , lets take the mean like this ,

-16 ,  -16+d , -16+2d ,-16+3d , 4

First mean -: -16 +d = 4

                   d= 4+16

                   d = 20

second mean -: -16 +2d = 4

                            2d=  4+16 = 20

                             d= [tex]\frac{20}{2}[/tex]

                             d= 10

third mean -: -16+3d = 4

                         3d = 20

                          d=[tex]\frac{20}{3}[/tex]

Therefore , all the three arithmetic means between -16 ad 4 are 10 , 20 and  [tex]\frac{20}{3}[/tex] .

Answer:

Step-by-step explanation:

3x^2 + 8x - 16 - SOMETHING = x^2 - 4

Re-arranging left and right:

SOMETHING = 3x^2 + 8x - 16 - x^2 + 4

= (3x^2 - x^2) + 8x - 16 + 4

= 2x^2 + 8x - 12

Answer:

Original expression:  [tex]3x^2+8x-16[/tex]

Let [tex]a[/tex] be the quantity Amir subtracted from the original expression.

Expression after subtraction: [tex]x^2-4[/tex]

[tex]\implies (3x^2+8x-16)-a=x^2-4[/tex]

Solve for [tex]a[/tex]:

[tex]\implies 3x^2+8x-16-a=x^2-4[/tex]

Add 4 to both sides:

[tex]\implies 3x^2+8x-12-a=x^2[/tex]

Subtract [tex]x^2[/tex] from both sides:

[tex]\implies 2x^2+8x-12-a=0[/tex]

Add [tex]a[/tex] to both sides:

[tex]\implies 2x^2+8x-12=a[/tex]

Therefore, Amir subtracted [tex]2x^2+8x-12[/tex] from the original expression.
