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

Find the measure of each angle indicated. Round to the nearest tenth.
Answer:
theta = 22.6 degrees
Step-by-step explanation:
Here, we want to find the value of theta
To do this , we use the appropriate trigonometric identity
Let us identify the given sides of the triangle
we have the hypotenuse, which is the longest side of the triangle, given as 13 and the third side called the adjacent, given as 12
The trigonometric identity that relates the hypotenuse to the adjacent is the cosine
Mathematically;
cosine of an angle is the ratio of the adjacent to the hypotenuse
Thus, we have it that;
cos theta = 12/13
theta = arc(cos) 12/13
theta= 22.6

1/3(c) when c = 64. What’s the answer using PEMDAS
Answer:
21.3 repeated
Step-by-step explanation:
Let's look at our equation
1/3c
We also have the number that c stands for, which is 64, so what we must do is replace c with 64.
1/3(64)
Now we have the equation 1 over 3 multiplied by 64, so multiply as is.
64 * 1 = 64
Therefore,
64/3
Now divide :

During a theater matinee show, the power went out. The theater manager refunded the
ticket price to everyone attending. Let n represent the number of people attending the
show. Let r represent the total amount of money refunded. Wite an equation to represent
the amount of money refunded.
Ticket Price Board
Adults
$13.00
Children & Seniors
$11.00
Matinees: All Ages
$9.00
Answer:
r = 9n
Step-by-step explanation:
Ticket price of each tickets for the matinee show = $9 for all ages
If the number of persons who attended the matinee show = n
And the total amount refunded = r
Then the expression representing total amount refunded 'n' in terms of 'r' will be,
Total amount refunded = Price of ticket × Number of tickets
r = 9n
