A jar contains 770 beans. Of them, 350 are mung beans and the rest are kidney beans. What is the ratio of mung beans to all the beans?
Answer:
5 MB : 16 B
Step-by-step explanation:
First, find the GCF of 770 and 350. ( 70 )
Next, divide both numbers by 70
770 / 70 = 11 Kidney beans
350 / 70 = 5 Mung beans
It says ratio of mung beans to all beans.
11 KB + 5 MB = 16 B

Elizabeth runs a farm stand that sells apples and raspberries. Each pound of apples sells for $2.25 and each pound of raspberries sells for $1.50. Elizabeth sold 32 more pounds of raspberries than pounds of apples and made $108 altogether. Graphically solve a system of equations in order to determine the number of pounds of apples sold, x, and the number of pounds of raspberries sold,y.
Answer:
Im confused?
Step-by-step explanation:
The number of pounds of apples is 16 and the number of pounds of raspberries is 48.
Given that, the cost of a pound of apples = $2.25 and the cost of a pound of raspberries = $1.50.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Let the number of pounds of apples be x, then the number of pounds of raspberries(y) be y=x+32.
Now, the total cost of apples = The number of pounds of apples × The cost of a pound of apples
=x × 2.25
= 2.25x
The total cost of raspberries = The number of pounds of raspberries × The cost of a pound of raspberries
=(x+32) × 1.50
=1.50x+48
So, the total cost = The total cost of apples + The total cost of raspberries
⇒108 = 2.25x+1.50x+48
⇒3.75x=60
⇒x=16
So, y=x+32=48
The graph is plotted below for y=x+32=48
Therefore, the number of pounds of apples is 16 and the number of pounds of raspberries is 48.

9x + 2y = 5; y
Answer:
{x,y}={ 5/9,0}
Step-by-step explanation:
9x - 2y = 5
y = 0
9x - 2•() = 5
9x = 5
x = 5/9
By now we know this much :
x = 5/9
y = 0
⇒{x,y} = {5/9,0}
Answer:
Please check the explanation.
Step-by-step explanation:
Given the equation
[tex]9x + 2y = 5[/tex]
solving the equation for y
[tex]9x + 2y = 5[/tex]
Step 1: Add -9x to both sides
[tex]9x+2y+-9x=5+-9x[/tex]
[tex]2y=-9x+5[/tex]
Step 2: Divide both sides by 2
[tex]\frac{2y}{2}=\:\frac{-9x+5}{2}[/tex]
[tex]y=\frac{-9}{2}x+\frac{5}{2}[/tex]
Thus, the value of y is:
[tex]y=\frac{-9}{2}x+\frac{5}{2}[/tex]
If we put y = 0 in the [tex]9x + 2y = 5[/tex]
[tex]9x+\left(0\right)=5[/tex]
[tex]9x=5[/tex]
[tex]\mathrm{Divide\:both\:sides\:by\:}9[/tex]
[tex]\frac{9x}{9}=\frac{5}{9}[/tex]
[tex]x=\frac{5}{9}[/tex]
Thus, the value of x=5/9 at y=0

Tamara wants to calculate the height of a tree outside her home. Using her clinometer (angle measuring device) she measures the angle from 35 feet away from the base of the tree and gets an angle of 62 degrees Tamara's eye level is 5.5 feet above the ground.
1. What trigonometric relationship (sine, cosine or tangent) would be used to determine how tall the tree is?
2. Write an equation to determine how tall the tree is, in feet.
3. How tall is the tree, in feet? Round your answer to the nearest tenth.
4. Marcus lives across the street from Tamara Marcus's eye-height is 4.25 feet, and he estimates that he views the top of the tree with an angle of elevation of 50 degrees and is standing 65 feet away from the tree. Are Marcus's estimates reasonable? Explain why or why not.
Answer:
61.922 feet
Step-by-step explanation:
For this problem, we simply want to set up a trigonometric function that computes the height of the tree, and we want to add the height of Tamara.
We are given a distance from the tree of 30 feet with an angle from her eye-level to the top at 62 degrees. So we can say the following:
y = tan(Θ) * x
Where Θ = 62 degrees, x = 30 feet, and y is the height of the tree from Tamara's eye level.
y = tan(Θ) * x
y = tan(62) * 30
y = 56.422
So we also need to include the height of Tamara to get the total height of the tree from the ground to the top.
56.422 ft + 5.5 ft = 61.922 ft
Hence, the total height of the tree is 61.922 feet.
The height of the tree is 71.32 feet.
What are trigonometric identities?Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
We set up a trigonometric function to get height of tree.
Distance ,
x = 35 feet away from tree base
Angle = 62⁰ at eye level
Then we get;
Y = tan(angle) x
Y = tan(62⁰) x 35
Y = 1.881 x 35
Y = 65.82 feet
We add Tamara's height to the total height of the tree that forms an equation as;
= 65.82feet + 5.5 feet
= 71.32 feet is the height of the tree
The height of the tree is 71.32 feet.

G. [tex] \frac{3.2}{2} = \frac{a}{8} [/tex]
Step-by-step explanation:
Given that figure I and figure II are similar, it follows that the ratio of their corresponding side lengths are equal and the same.
Thus:
[tex] \frac{3.2}{2} = \frac{a}{8} = \frac{8}{5} = \frac{6.4}{b} [/tex]
Therefore, the proportion that must be true is:
✔️[tex] \frac{3.2}{2} = \frac{a}{8} [/tex]
half of the substance to remain is called the half-life of the substance.
The half-life of a pesticide is 10 years. A farmer initially applies 200 grams of the
pesticide to a fence post.
Complete the following statements.
After 20 years, there are
grams of pesticide left. Round your answer
to the nearest whole gram.
After 60 years, there are
grams of pesticide left. Round your answer
to the nearest hundredth of a gram.
After
years, there are approximately 1.03 grams of pesticide
left. Round your answer to the nearest whole year.
Answer:
Instructions are below.
Step-by-step explanation:
To calculate the final amount if a given substance, we need to use the following formula:
final amount= initial amount / (2^n)
n= elapsed time / half-life
For 20 years:
n= 20/10= 2
Final amount= 200/(2^2)
Final amount= 50 grams
For 60 years:
n= 60/10= 6
Final amount= 200/ (2^6)
Final amount= 3.125 grams
To calculate the elapsed time it is more complicated:
elapsed time= ln(ending amount/beginning amount) / (-decay constant)
ln= natural logarithm
decay constant= ln(2) / half-life
decay constant= 0.0693
elapsed time= ln(1.03/200) / (-0.0693)
elapsed time= 76.028
Prove:
n= 76.02/10= 7.602
Final amount= 200/(2^7.602)= 1.03 grams
