Allison can make four parfaits because you need 1/8 cup of yogurt and Allison has 1/2 cup of yogurt. So the half of the cup would give her 4 * 1/8 to equal 1/2.

The perimeter of a triangle is 93 ft. Side a of the triangle is twice as long as side b. Side c is 3 ft longer than side a. Find

Sunny_sXe [5.5K]

The length of side a is 36 feet and side b is 18 feet and side c is 39 feet

Solution:

Given that perimeter of triangle is 93 feet

The three sides of triangle are a, b, and c

Given that Side a of the triangle is twice as long as side b

side a = 2 times side b

a = 2b

$b = \frac{a}{2}$ ---- eqn 1

Given that Side c is 3 ft longer than side a

side c = 3 + side a

c = 3 + a ------ eqn 2

The perimeter of triangle is given as:

p = a + b + c

Where a, b, c are the length of sides of triangle

Substitute eqn 1 and eqn 2 in above formula

$p = a + \frac{a}{2} + 3 + a$

Given that perimeter = 93

$93 = a + \frac{a}{2} + 3 + a\\\\93 = \frac{2a + a + 6 + 2a}{2}\\\\93 \times 2 = 2a + a + 6 + 2a\\\\186 = 5a + 6\\\\5a = 186 - 6\\\\5a = 180\\\\a = 36$

Thus length of side a = 36 feet

Length of side b :

from eqn 1

$b = \frac{36}{2} = 18$

b = 18 feet

Length of side c:

From eqn 2,

c = 3 + 36 = 39

c = 39 feet

Thus length of side a is 36 feet and side b is 18 feet and side c is 39 feet

Janet is buying a $28 necklace. The store reduces the price by 20% and then applies a $2 off coupon. How much will Janet pay for

Leokris [45]

Okay well the starting is 28 dollars, right. But since there is a 20 percent discount, you have to turn 20% to a decimal. That means moving the decimal sign twice to the left to make it .20. From the it would be .20*28, that should equal 5.6. Now, that 5.6 is the amount you have to take away, it is the price of the sale. From then, you subtract which is 28-5.6 which should be 22.4. From that 22.4 you now take away two dollars and then it should be 22.4-2 which should be 20.4. Now that is your answer, 20.4.

What type of chart or graph would you use to compare individual family members’ daily water usage?

Ahat [919]

Answer:

Use a line graph with multiple lines.

Step-by-step explanation:

Since line graphs show data over time, and you have multiple people, this is a perfect choice. Put the days or however amount of time on the x axis, and the gallons or a different water amount on the y-axis. Color-code the lines to each family member.

An angle with a measure of would be classified as which type of angle? a. acute b. obtuse c. right d. straight

REY [17]

Since the given angle is less than 60 degrees which is less than 90 degrees, hence the measure that would be classified as the given angle is acute angle.

<h3>Lines and angle</h3>

A line is the shortest distance between two points where. the points where two lines meet is an angle.

There are several types of angles including acute, obtuse, right and straight

For acute angle, the angle is less than 90 degrees

For obtuse, the angle is greater than 90 and less than 180 degrees

For right angle, the angle is 90 degrees

Since the given angle is less than 60 degrees which is less than 90 degrees, hence the measure that would be classified as the given angle is acute angle.
