A mango weighs 36 ounces. The total weight of 3 magoes and 1 apple is the same as the weight of 5 apples. How much does 1 apple

Vadim26 [7]

Data:

M (mango)
A (apple)

We have:
1M = 36 ounces
3M + 1A = 5A

Replace and solving:

$3M + 1A = 5A$
$
3.(36) + 1A = 5A$
$108 + 1A = 5A$
$108 = 5A - 1A$
$108 = 4A$
$4A = 108$
$A = \frac{108}{4}$
$\boxed{A = 27}$

Answer:
Aple weigh 27 ounces

A weather balloon is launched from the ground at a spot 250 yards from a 65 foot royal palm tree . What is the minimal angle of

ValentinkaMS [17]

Answer:

Angle of elevation at which the balloon must take off in order to avoid hitting the tree is 5 degrees

Step-by-step explanation:

Given:

The height of the tree = 65 foot

The distance between the tree and the spot from which the balloon is launched = 250 yards

To find:

The angle of elevation at which the balloon must take off in order to avoid hitting the tree = ?

Solution:

Converting the yards to feet

1 yards = 3 feet

250 yards = 3 x 250 = 750 yards

Refer the below figure, The angle x is the angle of elevation at which the the ball must be thrown so that it does not Hit the tree

$tan(x) = \frac{opposite}{adjacent}$

Substituting the values

$tan(x) = \frac{65}{750}$

$tan(x) = 0.086$

$x = tan^{-1}(0.086)}$

$x = 4.91^{\circ}$

$x \approx5^{\circ}$

CD is the segment bisector of AB at D. If AD = 4x-1 and DB = 9x-21. what is the length of AD and AB

Artemon [7]

Answer:

AD= 15

AB=30

Step-by-step explanation:

We are given that the Point D bisect the line segment AB

Hence AD = DB

AD= 4x-1

BD=9x-21

Hence

4x-1=9x-21

adding 21 on both sides and subtracting 4x from both sides

4x-4x-1+21=9x-4x-21+21

-1+21=5x

5x=20

dividing both sides by x we get

x=4

Hence

AD = 4x-1

= 4(4)-1= 16-1=15

AD= 15

AB = 2 x AD

= 2 x 15

= 30

I need help with both questions please !!!!!

Keith_Richards [23]

Answer:

a) z=5w-3

we have w, so we multiply it by 5 to make it 5w

and then we subtract 3 to make it 5w-3

w⇒ ×5 ⇒ -3 ⇒ z

b) x⇒ +2 = x+2

Now × 7 makes it 7(x+2)

so y=7(x+2)
