mixas84 [53]

Answer:

Hence Nell's mom Chocolate milk is more Chocolaty.

Step-by-step explanation:

Given:

Chocolate syrup used by Nell's mom  = 30 ml

Amount of milk used = 2 ounces.

We will first find Amount of chocolate syrup used in 1 ounce of milk.

Now In 2 ounces of milk = 30 ml of chocolate syrup.

So in 1 ounce of milk = Amount of Chocolate syrup used for 1 ounce milk.

By using Unitary method we get;

Amount of Chocolate syrup used for 1 ounce milk= \frac{30}{2}=15\ ml

Hence For every 1  ounce of milk Nell's mom uses 15 ml of chocolate syrup.

Also Given:

Chocolate syrup used by Nell's dad  = 65 ml

Amount of milk used = 5 ounces.

We will first find Amount of chocolate syrup used in 1 ounce of milk.

Now In 5 ounces of milk = 65 ml of chocolate syrup.

So in 1 ounce of milk = Amount of Chocolate syrup used for 1 ounce milk.

By using Unitary method we get;

Amount of Chocolate syrup used for 1 ounce milk= \frac{65}{5}=13\ ml

Hence For every 1  ounce of milk Nell's dad uses 13 ml of chocolate syrup.

Since The amount of chocolate syrup used by Nell's mom is more than Nell's dad.

Hence Nell's mom Chocolate milk is more Chocolaty.

A woman saw oranges and mangos ad the market. She bought some oranges at 35 cents each and some mangoes at $1.00. if she bought
marysya [2.9K]

Answer: 20 oranges and 5 mangoes

Step-by-step explanation:

Define the following:

x = number of oranges

y = number of mangoes

Make the following system of equations:

x + y = 25

0.35x + 1.00y = 12.00

Solve for x:

y = 25 - x

⇒ 0.35x + 1.00(25 - x) = 12.00

⇒ 0.35x + 25 - x = 12.00

⇒ -0.65x = -13.00

⇒ x = 20

Solve for y:

20 + y = 25

y = 5

∴ 20 oranges and 5 mangoes were purchased.

What is the value of y?<br><br><br><br> Enter your answer in the box.<br><br> y =
Olenka [21]

Answer:

y=40\°

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal angles

The two equal angles are called the base angles and the third angle is called the vertex angle

In this problem the triangle ABC is an isosceles  triangle

so

AB=AC

5x=40\°

x=8\°

The sum of the internal angles of a triangle is equal to 180\°

so

Find the value of y

(2y+20)\°+2(40\°)=180\°

2y=180\°-20\°-80\°

2y=80\°

y=40\°
