Tammy sells wedges of cheese at the local farmers' market. To make the wedges, she cuts a big 5-pound block of cheese into 16 pieces. How much does each wedge of cheese weigh?
Answer: 5/16 pound or 0.3125 pounds
Step-by-step explanation:
From the question, we are informed that in order for Tammy to make the wedges, she cuts a big 5-pound block of cheese into 16 pieces.
The weight of each wedge of cheese will be gotten by dividing 5 by 16. This will be:
= 5/16 pound
= 0.3125 pounds
Answer:
5/16
Step-by-step explanation:

105 calories in bananas. 75 calories in apples. If Mary only eats these fruits and her total calorie intake is 1215 how many of each fruit did she eat
Answer:
3 bananas and 12 apples.
Step-by-step explanation:
105b+ 75a = 1215 where b is number of bananas and a is number of apples.
Divide each number by 15:
7b + 5a = 81
5a must end in 5 or 10 so 7b must end in 1 or 6.
So we try:
21 and 60:
7 * 3 + 5 *1 2 = 81
So b = 3 and a = 12.
The solution is
The number of bananas is = 3 bananas
The number of apples is = 12 apples
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of apples be = a
Let the number of bananas be = b
Now , the equation will be
The number of calories in bananas = 105 calories
The number of calories in apples = 75 calories
The total calories Mary takes = 1215 calories
So ,
Total calories Mary takes = number of apples x number of calories in apples + number of bananas x number of calories in bananas
Substituting the values in the equation , we get
75a + 105b = 1215
Divide by 15 on both sides of the equation , we get
5a + 7b = 81
So , substituting the values of a = 12 and b = 3 , we get
5 ( 12 ) + 7 ( 3 ) = 81
60 + 21 = 81
81 = 81
Therefore , the vale of a is 12 and value of b is 3
Hence ,
The number of bananas is 3 bananas
The number of apples is 12 apples

Step-by-step explanation:
We know that 1/2 are apples and 1/3 are bananas
we also know that
apples+bananas+oranges=1
Which means that
1/2+1/3+oranges=1
Add 1/2 + 1/3 by getting the denominators equal
3/6+2/6=5/6
Which means that 5/6+oranges=1
1-5/6=1/6
1/6
write everything below this
1/2+1/3+oranges=1
1/2+1/3=5/6
5/6+oranges=1
oranges=1-5/6

Which expression is equivalent to 2(8n)^4
Answer:
2* 8n* 8n* 8n*8n
Step-by-step explanation:
Break it down 2(8n)^4 because 4 is the exponent you will multiply 8n four times so it will be 8n*8n*8n*8n so add the 2 to it and it will be 2*8n*8n*8n*8n. Hope this help :)

There are 195 adults and 320 children at a zoo. The zoo makes a total of $6,515 from the entrance fees, and the cost of an adult and a child to attend is $27, how much does it cost each for a parent and a child? Let a represent an adult. Let c represent a child. Enter a system of equations to represent the situation, then solve the system.
Answer:
a+c=27
195a+320c=6515
Step-by-step explanation:
adult (a): 195
children (c): 320
total $: $6515
child $: 27
a+c=27 --> c=-a+27
195a+320c=6515
sub the first equation into the 2nd equation to get a=17
sub a=17 into c=-a+27 to get c=10
so, an adult ticket is $17 and a child ticket is $10.
The measure of angle R is 3 degrees less than twice the measure of angle S. If the sum of the measures of the two angles is 72 degrees, find the measure of each angle.
Measures of the given angles:
∠S = 25° and ∠R = 47°
What is an angle?In geometry, an angle is formed when two rays are joined at their endpoints. These rays are called the sides or arms of the angle.
There are two main parts related to an angle - the arms and the vertex.
Given,
Measure of angle R is 3 degrees less than twice the measure of angle S
⇒ 2∠S - ∠R = 3°
⇒ ∠R = 2∠S - 3° ------(a)
Sum of R and S
⇒ ∠R + ∠S = 72°
Substituting ∠R in terms of ∠S in above equation from equation (a)
2∠S - 3° + ∠S = 72°
3∠S - 3° = 72°
3∠S = 72° + 3°
3∠S = 75°
∠S = 75°/3
∠S = 25°
Substituting value of ∠S in equation (a)
∠R = 2 × 25° - 3°
∠R = 50° - 3°
∠R = 47°
Hence, ∠S = 25° and ∠R = 47° are the measures of given angles.

We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
The area of the triangle.
= 1/2 x base x height
Now,
Base = 4 units
Heights = 3 units
So,
Area = 1/2 x 4 x 3 = 6 units²
Now,
It is twice the area of a square of the side length of 4 units.
6 units² < 16 units²
This is not true.
It is one-half the area of a square of side length 4 units.
1/2 x 16 units² = 6 units²
8 units² = 6 units²
This is not true.
It is twice the area of a rectangle with sides 4 units x 3 units.
2 x 12 units² = 6 units²
24 units² = 6 units²

A construction crew is building a two story house, but they have not built the staircase between the floor yet. The height of the staircase is 12 feet, the base of the stairs will be 6 feet from the wall. How long does the temporary ramp need to be to the nearest tenth of a foot?
Answer:
13.4feet
Step-by-step explanation:
The set up forms a right triangle.
Given
Height of the staircase h = 12 feet
Base of the stairs b = 6feet
Required
Length of the ramp l
Using the pythagoras theorem
l² = h² + b²
l² = 12²+6²
l² = 144 + 36
l² = 180
l = √180
l = 13.42 feet
Hence the length of the ramp to the nearest tenth is 13.4feet
interest earned:? principal: 250$ interest rate: 4% time: 2 years
First begin with the interest formula.
Interest = Principal x Rate x Time
The $250 is the principal is the amount of money invested.
The rate is 4% which translates to the decimal .04.
The time is 5 years.
So we have I = (250)(.04)(2).
Multiplying, (25)(.04) is 10 and we have 10(2) which is 20.
This means that the interest earned in 2 years is $20.
