This table shows a proportional relationship between the number of cups of bananas and apples used for a smoothie.
Cups of
Bananas
Cups of Apples
1

2
12
4
24
Enter the number of cups of bananas used for 1 cup of apples.
cups
Answers
Answer:
For every 1 cup of banana you have to add 6 cups of apples. So it means there's six times as much apples as there is bananas. If there's 3 cups of apples, which is half of 6, it means the banana would now also have to be halved from 1 to half a cup.
Whatever you do to the bananas or the apples, you have to maintain the same ratio. Which is that apples is 6 times as much as bananas.
So 1 cup of apple would need to be divided by 6, to get banana. That would be approximately 1÷6= 0.167 cups

There are 40 people at a party. If 8 boys leave and 2 girls come, then the number of boys will be equal to the number of girls. Find the initial number of boys and girls.
Answers
Answer:
25 boys, 15 girls
Step-by-step explanation:
You can setup 2 equations where b is the number of boys and g is the number of girls to get [tex]b+g=40[/tex] and [tex]b-8=g+2[/tex]. Simplifying the second equation gets you [tex]b-10=g[/tex] insert [tex]b-10[/tex] for g in the first equation to get [tex]2b-10=40[/tex]. Simplify this equation to get [tex]b=25[/tex]. To find the number of girls, substitute 25 for b in the first equation to get [tex]g=15[/tex]

What’s the area and perimeter
Answers
Answer:
Step-by-step explanation:
1. ✔️Using Pythagorean Theorem, thus the missing length, x, would be:
x² = 19² - 17² = 72
x = √72
x = 8.5 (nearest tenth)
✔️Area = ½*b*h
b = 17
h = 8.5
Area = ½*17*8.5 = 72.25 units²
✔️Perimeter = 19 + 17 + 8.5 = 44.5 units
2. ✔️Using Pythagorean Theorem, thus the missing length, x, would be:
x² = 5² + 13² = 194
x = √194
x = 13.9 (nearest tenth)
✔️Area = ½*b*h
b = 13
h = 5
Area = ½*13*5 = 32.5 units²
✔️Perimeter = 13 + 5 + 13.9 = 31.9 unit
3. ✔️Using Pythagorean Theorem, thus the missing length, x, would be:
x² = 20² - 10² = 300
x = √300
x = 17.3 (nearest tenth)
✔️Area = ½*b*h
b = 17.3
h = 10
Area = ½*17.3*10 = 86.5 units²
✔️Perimeter = 17.3 + 10 + 20 = 47.3 unit
4. ✔️Using Pythagorean Theorem, thus the missing length, x, would be:
x² = 5² + 14² = 221
x = √221
x = 14.9 (nearest tenth)
✔️Area = ½*b*h
b = 14
h = 5
Area = ½*14*5 = 35 units²
✔️Perimeter = 14.9 + 14 + 5 = 33.9 unit

What is sin 28°?
I need help ASAP
Answers
Answer:
sin 28° = 8/17
Step-by-step explanation:
sin A = opp/hyp
sin 28° = 8/17
The value of sin 28° is: sin 28° = 8/17
So, Option B is correct.
Here, given that, a right angle triangle has hypotenuse = 17 units,
height = 8 units,
base = 15 units.
now, we have, the angle between hypotenuse and base is: sin 28°.
from trigonometry we know that,
sin A = opp/hyp
so, here, we get, sin 28° = height/hypotenuse
putting the values, we have,
sin 28° = 8/17
Hence, The value of sin 28° is: sin 28° = 8/17
So, Option B is correct.

Step-by-step explanation:
a. Fill in the equation for the cost of Mrs. Ortiz's purchase. Let x represent the cost of a pencil and y represent the cost of a ruler.
__$55__ = __50__ x + __30_ y
b. Fill in the equation for the cost of Mr. Donahue's purchase. Let x represent the cost of a pencil and y represent the cost of a ruler.
__$45__ = __30__ x + __30__ y
c. Circle the best method for solving the system:
Elimination
d. Solve the system using the method you chose.
55 =50x+30y
-1(45) =(30x+30y)-1 = -45=-30x-30y
55 =50x+30y
+ -45=-30x-30y
10=20x
(1/20)10=20x(1/20)
0.50=x
3(55) =(50x+30y )3 = 165=150x+90y
-5(45) =(30x+30y)-5 = -225=-150x-150y
165 =150x+90y
+ -225=-150x-150y
-60=-60y
(1/-60)-60=-60y(1/-60)
1=y
A mechanical pencil costs _$0.50__ and a ruler costs __$1.00__.
e. Check your answer:
$55=50x+30y $45=30x+30y
$55=50(0.5)+30(1) $45=30(0.5)+30(1)
$55=25+30 $45=15+30
$55=$55 $45=$45
A mechanical pencil costs $0.50 and a ruler costs $1.00.
What is meant by cost?In calculus, a cost function is a mathematical formula used to determine how much it will cost to produce a certain number of units. The total cost formula is used to calculate the total cost by combining the variable and fixed costs of providing goods. Total cost = (average fixed cost x average variable cost) x number of units produced. A unit price is defined as a price expressed as a quantity of one, such as $25 per ticket or $0.89 per can. If you have a non-unit price, such as $5.50 for 5 pounds of potatoes, and want to find the unit price, divide the terms of the ratio.The current answer as follows:
a. Fill in the blanks to calculate Mrs. Ortiz's purchase price. Let x denote the price of a pencil and y the price of a ruler.
$55 = 50x + 30y
b.Fill in the blanks with the cost of Mr. Donahue's purchase. Let x represent the cost of a pencil and y represent the cost of a ruler.
$45 = 30x + 30y
c. Circle the best method for solving the system:
Elimination
d. Solve the system using the method you chose.
55 = 50x + 30y - 1(45) = (30x + 30y) - 1 = -45 = -30x - 30y
55 = 50x + 30y + -45 = -30x - 30y
10 = 20x
(1/20)10 = 20x (1/20)
0.50 = x
3(55) = (50x + 30y )3 = 165 = 150x + 90y
-5 (45) = (30x + 30y) - 5 = -225 = -150x - 150y
165 = 150x + 90y + -225 = -150x - 150y
-60 = -60y
(1/-60) -60 = -60y (1/-60)
1 = y
A mechanical pencil costs $0.50 and a ruler costs $1.00.

Amir’s average math score for the first 4 tests of the school year is 88 Which equation can be used to calculate what Amir’s average must be on the next two tests so that his overall average is 90
Answers
Answer:
Equation that can be used = [tex]\frac{4(88)+2x}{6} = 90[/tex]
Step-by-step explanation:
Given that:
Amir's average on four tests = 88
Let,
x be the score on one test
For two tests = 2x
Sum of all scores = Average of four tests + Score of two tests
Sum of all scores = 4(88) + 2x
Total number of tests = 6
Overall average needed = 90
Now,
[tex]Average = \frac{Sum\ of\ quantities}{Number\ of\ quantities}\\90 = \frac{4(88)+2x}{6}\\\\\frac{4(88)+2x}{6} = 90[/tex]
Hence,
Equation that can be used = [tex]\frac{4(88)+2x}{6} = 90[/tex]

Step-by-step explanation:
The proportion Jamie should set up is 14/5=25/x and 9 hours will it take Jamie to walk 25 miles
What is Ratio and Proportion?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.
Given that In 5 hours, Jamie walked 14 miles.
Jamie is trying to figure out how many hours it would take to walk 25 miles.
She set up the proportion 14/5=x/25.
The error Jamie make in setting up her proportion is in LHS taken as miles per hours but in RHS the set up is hours by miles.
In both sides same set up should be maintained.
14/5=25/x is the proportion she should have used
14/5=25/x
Apply cross multiplication
14x=25(5)
14x=125
x=125/14
x=8.92=9
Hence, the proportion Jamie should set up is 14/5=25/x and 9 hours will it take Jamie to walk 25 miles

The matrix form
A X = B
[tex]\left[\begin{array}{ccc}4&-1\\8&5\\\end{array}\right] \left[\begin{array}{ccc}x\\y\\\end{array}\right] = \left[\begin{array}{ccc}10\\34\\\end{array}\right][/tex]

|A| = ad-b c = 4(5) - 8(-1) = 20+8 = 28
Given matrix
