Mr.wayne repeat his tie every 12 days and mr pickett repeats his tie every 10 days.what day will they wear the same tie

Which graph represents a proportional relationship?

nikdorinn [45]

Answer:

On a coordinate plane, a straight line with positive slope goes through points (3, 3) and (4, 4).

Step-by-step explanation:

both points when divided (y÷x) should give the same answer for it to be proportional

meaning

4÷4 = 1 and 3÷3 = 1

Answer:

D. On a coordinate plane, a straight line with positive slope goes through points (3, 3) and (4, 4).

Explanation:

For a relationship to be proportional it needs to meet two conditions:

1) its graph needs to be a straight line

2) every point of the graph needs to satisty the equation y = k•x, or, in other words k has to be equal for every point

Now, let's check the answers;

A) we have two points: A (2, 6) and B (4, 5). For point A, x is 2 and y is 6, so:

y = k•x

6 = k•2

k = 3

For point B, x is 4 and y is 5, so:

y = k•x

5 = k•4

k= 5/4

Since k isn't the same value for these two points, this isn't proprtional relationship.

B) this graph is curve, so since it's not a straight line it can't be proportional relationship.

C) similarly to graph A we have point A (5, 2) and point B (6, 3).

For point A, x is 5 and y is 2, so:

y = k•x

2 = k•5

k = 2/5

For point B, x is 6 and y is 3, so:

y = k•x

3 = k•6

k = 1/2

Again values of k aren't the same, so this isn't a proportional relationship.

D) Point A (3, 3) and point B (4, 4). For point A, x is 3 and y is 3, so:

y = k•x

3 = k•3

k = 1

For point B, x is 4 and y is 4, so:

y = k•x

4 = k•4

k = 1

Since value of k is the same for both points, this graph shows the proportional relationship.

Answer:

D

Step-by-step explanation:

80 divided by 2 equals 40 and if you multiply it by 8 its 320 so the constant number is 40. So y=40x mean y=40^x

Care este cel mai mic număr dintre 95.999,96.959,99.595 și 99.995 la care cifra unităților de mii este 5

Triss [41]

Răspuns:

95.999

Explicație pas cu pas:

Care este cel mai mic număr între 95.999; 96.959; 99.595 și 99.995, unde numărul de mii este 5

95.999 = Nouăzeci și cinci de mii nouă sute nouăzeci și nouă

96.959 = Nouăzeci și șase de mii nouă sute cincizeci și nouă

99595 = Nouăzeci și nouă de mii cinci sute nouăzeci și cinci

99995 = Nouăzeci și nouă de mii, Nouă sute nouăzeci și cinci.

Folosind cunoștințele despre linia numerică:

95.999 <96.959 <99.595 <99.995

A single microvillus is a rod-like structure that is 1.0 μm in height. it has a hemispherical top approximately 0.1 μm in diamet

andre [41]

The surface area of the cylinder that forms the "sides" of the microvillus rod is given by the area of the curved surface of a cylinder with diameter (d) = 0.1 μm and height (h) = <span>1.0 μm.

The curved surface area of a cylinder is given by 2πrh, where r = d / 2 = 0.1 / 2 = 0.05 </span><span>μm.

Thus, the curved surface area is given by

$2(3.14)(0.05)(1.0) = 3.14 \times 10^{-11}\mu m^2$

Therefore, </span>the surface area of the cylinder that forms the "sides" of the microvillus rod is $3.14 \times 10^{-11}\mu m^2$

Choose the slope-intercept form of y 3 = 4(x – 5). y = 4x – 8 y = 4x 2 y = 4x 17 y = 4x – 23

KATRIN_1 [288]

Y + 3 = 4(x - 5)
y + 3 = 4x - 20
y = 4x - 20 - 3
y = 4x - 23
