Pennies made after 1984 weigh 2.5 grams. How much would 10 pennies weigh?

Answer:

Step-by-step explanation:

those are 2 lines, and to graph them find 2 points for each to draw a line trough them

line 1

y-2x=0 so y=2x

pick any value for x

(x=1, y=2*1=2), (x=3, y=2*3=6)

Draw a line trough points (1,2) and (3,6)

line 2

y=4x+3

(x=1, y=4*1+3=7), (x= -1, y= 4(-1)+3= -1)

Draw a line trough points (1,7) and (-1, -1)

Answer:

The velocity is 17 m/s

Step-by-step explanation:

To find the velocity, we find the first differential of the displacement

That will be

S’(t) = 16t + 1/t

We simply proceed to replace t with 1

That will give;

16(1) + 1/1

= 16 + 1 = 17 m/s

If you just want to know what is the least common multiple of 10 and 60, it is 60

Answer:

the lowest common factor is 5

Step-by-step explanation

5 can go into both 60 and 10, and thats the lowest that can go into both numbers because 5 times 2 is equal to 10 and 5 times 12 is equal to 60. hope this helps :)

Answer:

45 miles.

Step-by-step explanation:

Ok, so it goes 1.75 (1 3/4) miles in 2 minutes and 20 seconds, or 140 seconds. Divide 1.75 miles by 140 and you get 0.0125 miles per second, or 0.75 (3/4) miles per minute. Multiply 0.75 by 60 minutes and you get 45 miles.

Answer:b

Step-by-step explanation:

Answer:

The laws of multiplication state that when a negative number is multiplied by a positive number, the product will be negative. So, if considering a factor pair of a negative product, one of these factors must be negative and the other factor must be positive.

Answer: y=−7

Step-by-step explanation:

Add 55 to both sides. y=−12+5

Simplify  -12+5  to  -7

Step-by-step explanation:

an² = 182

When a = 2, n² = 182/2 = 91, n = 9.539...

When a = 5, n² = 182/5 = 36.4, n = 6.033...

Since 2 <= a <= 5, we have 6.033 <= n <= 9.539.

Therefore our possible values of n are 7, 8 and 9.

The possible values of n are 7, 8, 9

The given equation is:

an²  =  182

Make n the subject of the formula:

[tex]n^2=\frac{182}{a} \\n = \sqrt{\frac{182}{a}}[/tex]

Let us consider the minimum and maximum values of a:

when a = 2

[tex]n = \sqrt{\frac{182}{2}}\\n = \sqrt{91} \\n = 9.54[/tex]

When a = 5

[tex]n = \sqrt{\frac{182}{5}}\\n = \sqrt{36.4} \\n = 6.03[/tex]

We can conclude that 6.03 < n < 9.54

Since n is an integer, the possible values of n are 7, 8, 9

Answer:

2 flowers per vase

Answer:

impossible,unless number is zero

Answer:

73

Step-by-step explanation:

Number is xy

x+y=10  .....a

(10x+y) - 36 = 10y+x

10x-x+y-10y=36

9x-9y=36

9(x-y)=36

x-y=4 ....b

a+b: 2x = 14       x = 7

y = 10 - 7 = 3

The two digit number is 73

check:  7 + 3 = 10

73-36 = 37   (73 vs 37)

Answer:

-5/2 is located left of -1

Step-by-step explanation:

Here, we want to select the correct option

We are comparing two numbers and the one on the left is less than the one on the right

Now, on the number line, we should notice one thing

The thing is that numbers that are less than a certain number will be positioned at the left hand side of the number

So what we have here is that the smaller number -5/2 is placed at the left hand side of -1 since it is the smaller number

Step-by-step explanation:

Step 1: Define

We are given a right triangle. We can use PT to solve the missing length.

Step 2: Identify Variables

Leg a = √27

Leg b = 15

Hypotenuse c = x

Step 3: Solve for x

Part (a)

Lets say we had the two general vectors

u = (a,b)

v = (c,d)

The dot product is

u dot v = a*c + b*d

-------------------

Apply that rule to these specific vectors

u = (5, -2)

v = (0, 1)

So we get

u dot v = 5*0 + (-2)*1

u dot v = 0 - 2

u dot v = -2

Therefore,

(u dot v)*w = -2*(-1, -3)

(u dot v)*w = ( -2*(-1), -2(-3) )

(u dot v)*w = (2, 6)

Answer:  (2, 6)

=============================================

Part (b)

u = (5, -2)

5u = 5*(5, -2)

5u = (5*5, 5*(-2))

5u = (25, -10)

5u dot v = (25, -10) dot (0,1)

5u dot v = 25*0 + (-10)*1

5u dot v = 0 - 10

5u dot v = -10

Answer: -10

Answer:

... ... = .5

Step-by-step explanation:

I'm not sure if I'm right. But I got my answer by dividing 255 and 2 first

255 / 2 = 112.5

Then find out what 64 + 32 + 16.

64 + 32 + 16 = 112

Add 0.5 to get the same answer from 255 / 2

64 + 32 + 16 + 0.5 = 112.5
