John has a large number of pennies, dimes, and quarters. How many ways can he make $1.00out of his coins? Note that order doesn’t matter.

Answer:

6

Step-by-step explanation:

Given that :

The school children are going for a school field trip. There are total forty - six number of students for the field trip.

They are asked to form groups of seven students in a group.

Therefore they will form = [tex]$\frac{46}{7}$[/tex]

                                      = 6.5

Therefore there will 6 number of groups having 7 students. And the remaining  4 students will form another group.

So there will be 6 groups of seven in each group.

Answer:

7.33

Step-by-step explanation:

Answer:

x = 1

Step-by-step explanation:

3(x − 2) + 5 = 2(5x − 4)

Distributive property

3 * x - 3 * 2 + 5 = 2 * 5x - 2 * 4

3x - 6 + 5 = 10x - 8

Combine like terms

3x - 1 = 10x - 8

Add 8 on both sides

3x - 1 + 8 = 10x - 8 + 8

3x + 7 = 10x

Subtract 3x on both sides

3x - 3x + 7 = 10x - 3x

7 = 7x

Divide by 7 on both sides to isolate the variable

7/7 = 7x/7

1 = x

Check

3(x − 2) + 5 = 2(5x − 4)

Replace the "x" with 1

3 ( 1 - 2 ) + 5 = 2 ( 5 * 1 - 4)

3 * -1 + 5 = 2 * 1

2 = 2

Correct

Hope this helped!

Have a supercalifragilisticexpialidocious day!

Step-by-step explanation:

3(x - 2) + 5 = 2(5x - 4)

3x - 2 + 5 = 10x - 8

3x + 3 = 10x - 8

3x = 10x - 8 - 3

3x = 10x - 11

3x + 11 = 10x

11 = 10x - 3x

11 = 7x

11/7 = x

therefore, x = 1 4/ 7 ( mixed fraction form)

Answer:

2.48 seconds

Step-by-step explanation:

The given function is

[tex]y=-60t^2+4t+380[/tex]

When [tex]y=0[/tex] the ball will be at the ground

[tex]0=-60t^2+4t+380[/tex]

[tex]\Rightarrow t=\dfrac{-4\pm \sqrt{4^2-4\left(-60\right)\times 380}}{2\left(-60\right)}[/tex]

[tex]\Rightarrow t=-2.48,2.55[/tex]

So, the time taken by the rock to hit the ground is [tex]2.48\ \text{seconds}[/tex].

Answer: 435.24, 294.44 and 573.73.

Step-by-step explanation:

Helping dmitri sort his accounts from lowest to highest absolute value of account value will be for us to choose the smallest number first till the highest. Thus will be:

= -435.24, 294.44 and 573.73.

Answer:

B, x=5

Step-by-step explanation:

Both triangles are similar with a ratio of 22.5/9

so using that an equation can be created like this, [tex]\frac{22.9}{9}[/tex] = [tex]\frac{23.5}{x+4.4}[/tex]

If simplified, 22.9(x + 4.44) = 23.5(9)

22.5x + 99 = 211.5

22.5x = 112.5

x = 5

Answer: d

|4x + 1| ≤ 5

⇒ - 5 ≤ 4x + 1 ≤ 5

⇔ -6 ≤ 4x ≤ 4

⇔ -1.5 ≤ x ≤ 1

⇒ x ∈ [-1.5; 1]

Answer:

A. 8 gallons

B. Drive by car is $59.4 cheaper than travel by train

Step-by-step explanation:

According to the scenario, given data are as follows,

Total drive = 400 miles

Total drive per gallon = 50 miles

Fuel cost per gallon = $4.45

A. So, Total fuel required to drive 400 miles can be calculated as follows,

Total fuel required =  Total drive ÷ Total drive per gallon

By putting value, we get,

Total fuel required = 400 ÷ 50

= 8 gallons

B. Total cost if drive by car = 8 gallons × $4.45 = $35.6

Cost if travel by train = $95

Hence it is clearly shows that drive by car is much cheaper than travel by train.

Cost saved by travel by car = $95 - $35.6 = $59.4

So, drive by car is $59.4 cheaper than travel by train.

Answer:

Step-by-step explanation:

Y=1/3y+-5/3

Answer:

(a) Zeroes of the function is -2,4.

(b) The vertex of the parabola is (1,-9).

Step-by-step explanation:

Given,

f(x)=(x+2)(x−4)

(a)To find the zeros of the function put f(x)=0.

(x+2)(x-4)=0

x+2 = 0        or      x-4 = 0

x = -2,4

Hence, zeroes of the function is -2,4.

(b)Now,

f(x)=(x+2)(x−4)

[tex]f(x)= x^2 -2x+1 -1-8[/tex]

[tex]f(x)= (x-1)^2-9[/tex]  .......(i)

We know that,

If [tex]f(x)=a(x-h)^2 +k[/tex] is the equation of parabola the (h,k) is the vertex of the parabola.

On comparing with equation (i), we get

h = 1

k = -9

Hence, the vertex of the parabola is (1,-9).

Answer: A. 95

Step-by-step explanation: The angles in a triangle are supposed to add up to 180 degrees, 55+30= 85 and 85+95 is 180.

Answer:

166

Step-by-step explanation:

So the width is 65, so two sides are each 65m long. So multiply 65*2 which is 130. this means that the other two sides need to equal 130 when added, so divide 130/2 which is 65

Answer:

perimeter(p)=2(l+b)

2(l+b)=296

where b = 65

2(l+65)=296

2l+130=296

2l=296_130

2l=166

l=166÷2

l= 83
