A model satellite is 7 in wide. If it was built with a scale of 1 in: 2 yd, then how wide is the real satellite?​
miskamm [114]

Answer:

14yd

Step-by-step explanation:

 Scale of the model:

           1in  to 2yd

This suggest that for every 1in on the model, the actual distance is 2yd.

So;

          A model 7in wide will actually be:

               1in          to     2yd

               7in       will be 7 x 2  = 14yd

On Saturday, the bookstore sold x books. On Sunday, the bookstore sold 2 more books than on Saturday.
REY [17]
X = books were sold on Saturday.

Because 2 more books were sold on Sunday than on Saturday, therefore
(x + 2) books were sold on Sunday.

The total number of books sold over the weekend (Saturday and Sunday) is
x + (x+2)
= x + x + 2
= 2x + 2

Answer: 2x + 2

Someone please help me
pentagon [3]

Answer:

Option 3 or Option 4.

Step-by-step explanation:

I have this doubt because actually, a rhombus with a right angle (one) is not necessarily a square. Some rhombuses have one right angle and are still not squares. Now, if the four angles are right, it is a square, but this only says one.

On other hand, a parallelogram with congruent diagonals isn't a square necessarily either. Rectangles have congruent diagonals and are parallelograms.

In case you only can answer with one, I'll say is option 3, hope it helps!

2. Calculate the energy in joules of a photon whose frequency is 7.55×1014 Hz.
igomit [66]
The energy of a photon is given by
E = h × v

where:
E is the energy in joules/photon
'h' is the constant 6.63 × 10⁻³⁴
'v' is the frequency 7.55 × 10¹⁴

Substitute 'h' and 'v' into the formula we have

E = (6.63×10⁻³⁴) × (7.55×10¹⁴)
E = (6.63×7.55) × (10⁻³⁴ × 10¹⁴)
E = 50.0565 × 10⁽⁻³⁴⁺¹⁴⁾
E = 50 × 10⁻²⁰ joules/photon
