The owner of two grocery stores recorded the number of shoppers at each store for 10 days. On day 5, Store B had a sale. The number of shoppers per day at the stores are shown in the table.

Answer:

y^60

Step-by-step explanation:

(a^b)^b= a ^ b times b

12 times 5 is 60 so it's y^60

sorry my explaination is so complicated but im confident in the answer

Answer:

the temperature increased 1.25°c per hour

In those twelve hours the total increase was 15°c

Step-by-step explanation:

Divide the total temperature increase and the total of hours

[tex]15 \div 12 = 1.25[/tex]

and that's how you get how many degrees it increased each hour from midnight to midday

Answer:

50% change.

explanation:

change: $49.99 - $24.99 = $25

[tex]\sf percent \ change: \dfrac{\$25}{\$49.99} *100 \ \ = 50 \%[/tex]

Step-by-step explanation:

A black bar with 7 copper colored coils around it is the strongest.

Electromagnets are defined as magnet which works through electricity.

We know permanent magnets show magnetic properties every time. We cannot alter it. But electromagnets only acts as a magnet when current passes through it. Otherwise, it is just a coiled wire.

Strength of electromagnet depends on basically two things:

First, the amount of current flowing through the wire and

Second, the number of turns of wire around the coil.

Here there are four electromagnets which are black bar with 5, 2, 7 and 4 copper colored coils around it.

Number of coils is maximum for the black bar with 7 copper colored coils around it, which results in the strongest electromagnet.

Hence, a black bar having 7 copper colored coils around it is the strongest.

Answer:

C: y + 3 = 1/4(x + 4)

Step-by-step explanation:

Perpendicular to a given line means opposite inverse of the slope...

Equation of line is: y = -4x - 3

slope in above equation is -4, perpendicular would be 1/4

Perpendicular equation of a line through P(-4, -3):

y = mx + b

-3 = 1/4(-4) + b

-3 = -1 + b

b = -2

Use perpendicular slope and the b from above to form the perpendicular equation of line:

y = 1/4x - 2

Check:

(-3) = 1/4(-4) - 2

-3 = -1 - 2

-3 = -3

Answer:

Part 1

Multiply both sides by 2π

2πf = √(g/L)

Square both sides

4π²f²= g/L

Invert both sides

1/(4π²f²) = L/g

Multiply both side by g

g/(4π²f²) = L

We usually write an equation with the subject (L) n the left

L = g/(4π²f²)

________________________

Part 2

Using the above equation with the given values:

L = g/(4π²f²)

. .= 9.8 / (4π² x 1.6²)

. .= 0.097m (= 9.7cm)

________________________

By the way, where it says

“f=1.6 then there are 2 beats a second, or 192 beats per minute (bpm).”

this should say

“f=1.6 then there are 3.2 beats a second, or 192 beats per minute (bpm)”

Step-by-step explanation:

The values are L = g/(4π²f²) and L.= 0.097m (= 9.7cm)

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.

Here, we have,

Part 1

Multiply both sides by 2π

2πf = √(g/L)

Square both sides

4π²f²= g/L

Invert both sides

1/(4π²f²) = L/g

Multiply both side by g

g/(4π²f²) = L

We usually write an equation with the subject (L) n the left

L = g/(4π²f²)

________________________

Part 2

Using the above equation with the given values:

L = g/(4π²f²)

L.= 9.8 / (4π² x 1.6²)

L.= 0.097m (= 9.7cm)

Hence, The values are L = g/(4π²f²) and L.= 0.097m (= 9.7cm).

2x^2-22x-52

GCF = 22

2(x ^2 ​​ −11x−26)

2(x−13)(x+2)

Answer:

x = 2

Step-by-step explanation:

(2, 5) and (2, 9)

Ok. First, let's find the slope using the slope formula.

[tex]m = \frac{y2-y1}{x2-x1} =\frac{9-5}{2-2} = 4/0[/tex]

4/0 is undefined.

When the slope is undefined, that means that it's a straight line going down from the x.

So the equation is just x = 2

Answer:

see below

Step-by-step explanation:

Since the triangles are congruent

<A = <X

< B = < Y

<C = < Z

That means B = Y =  90

And C = Z = 37

The sum of the angles of a triangle are 180

A+ B+ C = 180

A + 90+37 = 180

A +127 = 180

A = 180-127

A =53

A = X = 53

We also know

AB = XY

BC = YZ

AC = XZ

AB = 3  so XY =3

YZ = 4  so BC =4

XZ = 5  so AC = 5

Answer: 36

Step-by-step explanation:

Answer: 3 3/4s' carpets

Step-by-step explanation:

Answer:

s=144

t=36

Step-by-step explanation:

you minus 180 from 36 and you get 144 for s

then you minus 180 from 144 to get t

Answer:

t = 36°

s = 108°

Step-by-step explanation:

FE and DE are congruent. This means that triangle ΔDEF is isosceles.

Base angles (∠EFD and ∠EDF) in isosceles triangles are congurent.

∠EFD is 36°. This means that ∠t is also 36°

The measure of all the angles in a triangle is 180°

[tex]36+36+x=180\\72+x=180\\x=108[/tex]

∠s = 108°

Answer:

y= 3x - 5

Step-by-step explanation:

coordinates given: (4,7) & (1, -2)

to find m (slope) = rise/run = (y2-y1) /(x2-x1)

= ( -2-7) / (1 - 4)

= -9/-3

= 3

therefore, y=3x + b

to find b:

taken coordinate: (4,7)

y=3x + b

7=3 (4) + b

7= 12 + b

7-12 = b

-5 = b

(*the value of b will be same even if we take the other coordinate)

therefore, y = 3x -5

B.) Yes; The graph passes the vertical line test!

Step-by-step explanation:

This graph does indeed show a function! A parabola, it looks like!

A function on a graph is determined when the function passes the vertical line test, meaning no matter where you go on the function, a specific vertical line will only pass through one point!
