Answer:

Step-by-step explanation:

His Mom got 5 necklaces with 12 shells each, so Cole used 5x12=60 shells on her necklaces. He then made one more for his sister, using another 12 shells. In total, he used 60 shells for his mom's necklaces and 12 for his sister's, equalling (60+12)=72.

28.5 g of iron shot is added to a graduated cylinder containing 45.50 mL of water. the water level rises to the 49.10 mL mark. F

Alika [10]

Density=mass/volume.
1) we have to calculate the iron volume in liters.
iron volume=second level - first level=49.10 ml-45.50 ml=3.6 ml
3.6 ml=3.6 ml(1 liter / 1000 ml)=0.0036 liters

2) we calculate the mass iron in kg.
28.5 g=28.5 g(1 kg /1000 g)=0.0285 kg.
2) we calculate the density of iron.
density=0.0285 kg / 0.0036 liters=7.92 kg/L

7.92 kg/l=7.92 kg/L(1000 g/1Kg)(1000 cm³/1 L)=7.92 g/cm³.

answer: From this information the Iron density is 7.92 Kg/L or 7.92 g/cm³.

A soccer ball has a 35 cm diameter. what is the volume of the contents of the ?

Anettt [7]

Answer:

To calculate the volume of a sphere, use the formula v = ⁴⁄₃πr³, where r is the radius of the sphere. If you don't have the radius, you can find it by dividing the diameter by 2. Once you have the radius, plug it into the formula and solve to find the volume.

Step-by-step explanation:

To find the volume of a soccer ball,the formula is V=4/3 πr^3,where r is the radius and π=3.14. A regulation soccer ball has a radius of 35cm. find the volume of a soccer ball to the nearest cubic centimeter. This is just some to keep in mind.

In the figure, angle D measures 45° and angle E measures 87°. What is the measurement of angle H? 42°

Vinvika [58]

The complete question is shown in the attached image

Answer:
measure angle H = 42°

Explanation:
There is a theorem that states that:
"In a triangle, the measure of the exterior angle is equal to the sum of the measures of the two non-adjacent angles to the exterior angle"

In the given, we have:
angle E is an exterior angle to triangle DFH
The two non-adjacent angles to angle E are angles D and H

Based on the above rule:
measure angle E = measure angle D + measure angle H

We are given that:
angle E = 87°
angle D = 45°

Substitute with the givens in the above rule and solve for the measure of angle H as follows:
angle E = angle D + angle H
87° = 45° + measure angle H
measure angle H = 87° - 45°
measure angle H = 42°

Hope this helps :)

A basketball team scored 102 points in a game. Each basket is 2 points and each free throw is 1 point. Write a standard for equa

marissa [1.9K]

Answer:

The equation representing the Total number of points is $2x+y=102$ .

Step-by-step explanation:

Given:

Total Point scored = 102

Let Number of basket scored be 'x'

Let Number of free throws be 'y'

Total Point Scored will be equal to sum of Number of basket scored multiplied by point scored in basket and Number of Free throws multiplied by point scored in free throws.

Framing the equation we get;

$2x+y=102$

Hence The equation representing the Total number of points is $2x+y=102$ .
