Minchanka [31]4 years ago
7 0

Answer:

the value of BD is 18.

Step-by-step explanation:

Our given are two triangles and these triangles are congruent. It means that they have the same measures of angles and sides.

ΔABD ≅ AFEC, based on this we find there equivalent sides and angles

AD ≅ FC (measures 19.7)

∠A ≅ ∠F (measures 63°)

FE ≅ AB (measures 12)

∠B ≅ ∠E (measures 72°)

∠D ≅ ∠C (measures 45°)

lastly BD ≅ CE (measures 18).

Felix wants to buy some lemonade for the dinner party.
Xelga [282]

Answer:

Yes. Felix is correct.

Step-by-step explanation:

Find out how much ml does a can of lemonade have, I would assume its 330ml since I searched up the ml of a lemonade can.

Find out how much cans of lemonade there are in 2 packs of 8.

2 packs = 8 x 2 = 16 cans of lemonade

Now find out how much ml 16 lemonade cans equal to.

1 can of lemonade = 330ml

16 cans of lemonade = 330 x 16 = 5280ml

Now let's find 5 bottles of 1 litre.

1 litre x 5 = 5 litres.

5280 = 5 litres and 280ml

So Felix is correct about 2 packs of 8 cans is more than 5 bottles of 1 litre.

a local hamburger shop sold a combined total of 770 burgers and cheeseburgers on Monday there were 70 more cheeseburger sold tha
aliina [53]
Let the number of hamburgers = h

Let the number of cheeseburgers = c

Now we translate the given information into equations.

"combined total of 770 [ham]burgers and cheeseburgers"
h + c = 770

<span>"there were 70 more cheeseburger sold than hamburgers"
</span><span>
</span><span>c = h + 70
</span><span>
</span><span>
</span><span>Our system of equations is
</span><span>
</span><span>
</span><span />h + c = 770
c = h + 70

The second equation is already solved for c, so we replace c of the first equation with h + 70.
h + h + 70 = 770
2h + 70 = 770
2h = 700
h = 350

Answer:  350 hamburgers were sold on Monday.

There are two cube-shaped tanks. One of the tank has a 3 m side, while the other one has a side measuring half of the first one.
Alexeev081 [22]

Answer: The tank which has 3 m side.

Step-by-step explanation: A cube is a form that has equal sides. To calculate the volume of it, multiply all three sides:

V = length*width*height

Since they are all the same, volume will be:

V = s³

One tank has a 3 m side, so its volume is:

V = 3³

V = 27 m³

The other has half of the first one side, then s = \frac{3}{2} and volume will be:

V = (\frac{3}{2})^{3}

V = \frac{27}{8} m³

As you can see, the volume of the second tank is \frac{1}{8} smaller than the first one. Therefore, the tank which has 3 m side can store more water than the  tank with side measuring half of the first.

weeeeeb [17]

Answer:

7/10 or 70%

Step-by-step explanation:

There has to be at least two T in each result of the simulation. This means you can also have 3 T's and 4 T's in the result.

These are the results that qualify as having at least two T's.

1. TTTT, 2. TTTT, 3. THTH, 4. HTTT, 5. TTTT, 7. HTHT, 9. THTH

That is 7 out of the 10 results which is 7/10 or 70%
