Answer:

Step-by-step explanation:

Write the ratio this way

Pip: Sara: Total

5 : 4 : 9

We multiply each by 10 to get Pip to 50 (5*10 = 50)

5*10: 4*10: 9*10

50 : 40 : 90

Answer:

$90

Step-by-step explanation:

Given that the ratio of Pip: Sara is 5:4

This means :

Pip gets 5 parts

Sara gets 4 parts

Together they have 5 + 4 parts = 9 parts

Also given that Pip's 5 parts is equivalent to $50

Hence each 1 part is $50/5 = $10

if 1 part = $10

The total 9 parts = 9 x $10 = $90

The sides of an isosceles triangle are 8, 8, and 3. The measure of the vertex angle to the nearest degree is _____°. 44 17 31 22

Doss [256]

We may draw a vertical that bisects the vertex angle and the shorter side of the triangle, to form a right-triangle with the measurements:
hypotenuse = 8
length = 1.5

We may then apply:
sin(∅) = P / H
sin(∅) = 1.5 / 8
∅ = 10.8 ≈ 11°

This is half of the vertex angle, so the vertex angle is:
11 * 2 = 22°

A 10-ft vertical post casts a 14-inch shadow at the same time a nearby cell phone tower cast a 119-ft shadow. How tall is the ce

Yakvenalex [24]

Answer:

The cellphone towers height is 1020 ft.

Step-by-step explanation:

This question is solved using proportions, by a rule of three.

A 10-ft post casts a 14-inch shadow.

Each feet has 12 inches, which means that a post with 10 feet will cast a 14/12 = 1.167 ft shadow. How tall is the cell-phone tower with a 119-feet shadow?

10 feet post - 1.167 ft shadow

x feet tower - 119 feet shadow

Applying cross multiplication:

$1.167x = 10*119$
