When Terri makes fruit salad she uses 4 oranges and 3 cups of grapes for every 2 bananas. If Terry uses five bananas how many oranges and how many cups of grapes will she use? Write and solve a proportion
Answer:
7.5 cups of grapes
Step-by-step explanation:
4o:3g:2b
With 5b, there's an increase in 2.5 from 2b. (divide 5b/2b)
Since the increase in all the other fruits is proportional by the same amount of 2.5.
This leaves you with 10o:7.5g:5b

Answer:
R would equal 12
Step-by-step explanation:
-4x+11y=-32
-9x+4y=11
elimination
Answer:
x = -3; y = -4
Step-by-step explanation:
We can start by eliminating x, which will give us y:
[tex]9(-4x +11y=-32)\\-4(-9x+4y=11)\\\\-36x+99y=-288\\36x-16y=-44\\\\83y=-332\\y=-4[/tex]
Now we can plug in -4 for y in the first equation to find x:
[tex]-4x+11(-4)=-32\\-4x-44=-32\\-4x=12\\x=-3[/tex]
Ashley's company makes solid spherical balls out of scrap metal for various industrial uses. A large order just came in to make aluminum balls with a radius of 4.5 in. If Ashley uses 74,325in^3 on average, of aluminum each day making these balls, how many balls does she make, on average, each day?
Using the formula of volume of a sphere, Ashely's company made 195 balls
Volume of SphereThe volume of sphere is the measure of space that can be occupied by a sphere. If we draw a circle on a sheet of paper, take a circular disc, paste a string along its diameter and rotate it along the string. This gives us the shape of a sphere.
The formula of volume of a sphere is given as
v = 4/3πr³
r = radius = 4.5in
volume of each spherical ball = 4/3π(4.5)³
volume of sphere = 381.7in³
The number of balls she made from 74325 in³ can be found by dividing it by 381.7in³
Number of balls = 194.7≅195 balls

Answer:
x = .5, - 1.5
Step-by-step explanation:
4x^2 + 4x =3
To solve for x, we can complete the square.
4 ( x^2 + x) = 3
x^2 + x = 3/4
Take the coefficient of x, divide by 2, and square.
(1/2)^2
Then add to each side.
x^2 + x + 1/4= 3/4 +1/4
(x+1/2) ^2 = 1
Take the square root of each side.
x+1/2 = ±1
x = ±1 -1/2
x = 1-1/2 or -1-1/2

Answer:
133, 412500, 500, 1.184, 37.8, 10, 0.6
Step-by-step explanation:
If we think about how many centimeters are in a meter, we know that
1m = 100cm
Using this, we can see that
20m = 2000cm
Now divide by 15:
2000 ÷ 15 ≈ 133
She can make roughly about 133 ribbons.
To solve the next question, we need to know how many kilometers are in a meter
1km = 0.001m
Let's covert 0.75 into m:
0.75 × 1000 = 750
Now solve for the area:
750 × 550 = 412500
The area of the rectangle is 412500
If he is selling the home for 206,250,000 pesos,
206,250,000 divided by 412500
206,250,000 ÷ 412500 = 500
The price per square meter is 500
If each glass is 148 milliliters, and we need to convert that into liters, we can use the equation:
1L = 1000mL
So converting 148 into liters,
148mL = 0.148L
Now, multiply by 8.
0.148 × 8 = 1.184L
We need to convert 100 Fahrenheit to Celsius.
100 F ≈ 37.8
This is definitely not a normal body temperature.
We can convert grams to kilograms using the equation:
1kg = 1000 g
Converting 2.5kg to g would look like this:
2.5kg = 2500g
250g × 10 = 2500g
We need to buy 10 packs of sugar.
If 120 grams of powdered milk can produce 60 cups of milk, and we need to figure out how many kg can produce the same amount, we use the equation:
1kg = 1000g
Converting 120g to kg would look like this:
120 ÷ 1000 = 0.120
Now, we need to figure out how many times 12 goes into 60.
12 × 5 = 60
Now we multiply 0.120 by 5
0.120 × 5 = 0.6
I hope this helps!

The quadratic equation y = x² - 8 · x + 18 represents the parabola shown in the figure.
How to derive the quadratic equation behind the graph of the parabola
In this problem we find a representation of a parabola, which is described algebraically by quadratic equations, that is, polynomials of the form:
y = a · x² + b · x + c
Where a, b, c are the coefficients of the polynomial.
We can determine the value of the coefficients from the knowledge of three points set on Cartesian plane. First, select the points from Cartesian plane:
(x₁, y₁) = (0, 18), (x₂, y₂) = (4, 2), (x₃, y₃) = (7, 11)
Second, create a system of linear equations with three variables and three equations by replacing the variables x and y on the quadratic equation:
c = 18
16 · a + 4 · b + c = 2
49 · a + 7 · b + c = 11
Third, solve the system by numerical methods:
(a, b, c) = (1, - 8, 18)
Fourth, write the resulting quadratic equation:
y = x² - 8 · x + 18

What are trigonometric ratio?
The ratio of sides of a right angled triangle is known ars trigonometric ratios. There are six trigonometric ratios. Which are as follows:
sin = P/H, cos = B/H, tan = P/B
cosec = H/P, sec = H/B, cot = B/P
Here, P is perpendicular, H is hypotaneous, and B is base. These ratios simplify the calculation.
SInce the angle is not specified hence, consider the given angle is L. Now, L is given angle hence, the base will be 15 and hypotenous will be 39.
Now, consider the trigonometric ratio of cos.

What is a personal protective equipment?Personal protective equipment (PPE) is clothing that is comfortable to wear in order to reduce the risk of hazards at work that cause serious illnesses and injuries.
Personal protective equipment (PPE) will be divided into the following categories for this purpose: eye and face protection, hand protection, body protection, respiratory protection, and hearing protection.
Personal protective equipment (PPE) should be used when all other measures to control exposure are ineffective. It only protects the wearer while they are wearing it. PPE offers no protection if it fails.
All personal protective equipment should be designed and built safely, and it should be kept clean and reliable. It should be comfortable for workers to use. Personal protective equipment that does not fit properly can mean the difference between being safe and being dangerously exposed. Employers must provide personal protective equipment to their employees and ensure its proper use when engineering, work practices, and administrative controls are not feasible or provide adequate protection
