A salsa recipe uses green pepper, onion, and tomato in the extended ratio 1 : 5 : 7. How many cups of onion are needed to make 117 cups of salsa?
Answer:
We need 45 cups on onion
Step-by-step explanation:
green pepper : onion: tomato: total
1 5 7 13
We have 117 total so divide by 13
117/13 = 9
Multiply each number by 9
green pepper : onion: tomato: total
1*9 5*9 7*9 13*9

While walking to school you pass a barn with a silo. Looking up to the top of the silo you estimate the angle of
elevation to the top of the silo to be about 14°. You continue walking and find that you were around 40 m from
the silo. What is the height of the silo?
Answer:
9.97 meters
Step-by-step explanation:
The silo is one leg of a right triangle the other leg is the distance from the silo
for a right triangle tan = opposite side / adjacent side
tan(14) = height/40
40 tan 14 = height = 9.97 m

The correct statement is the first one. g(x) exceeds f(x) by 72.
Which statement is true?
By looking at the table, we can see that f(x) is a linear function and g(x) is an exponential function, such that:
f(x) = 10 + 3x
g(x) = (1/2)^x
By evaluating these functions in x = -6 we get:
[tex]f(-6) = 10 - 3*6 = -8[/tex]
[tex]g(-6) = (1/2)^{-6} = 64[/tex]
The difference is:
g(-6) - f(-6) = 64 + 8 = 72
Then the correct option is the first one, g(x) exceeds f(x) by 72.

The hypotenuse of a right triangle measures 2 square root 15 centimeters and its shorter leg measures 2 square root 6
centimeters.
What is the measure of the larger acute angle of the triangle? Round your answer to the nearest
tenth of a degree.
Answer:
50.8°
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relationship between side lengths and trig functions for a right triangle. Here, you are given the short side and the hypotenuse, and asked for the largest acute angle.
__
The short side is adjacent to the largest acute angle, so the relevant relation is ...
Cos = Adjacent/Hypotenuse
cos(β) = (2√6)/(2√15) = √0.4
The angle measure is found using the inverse cosine function:
β = arccos(√0.4) ≈ 50.8°
The larger acute angle is about 50.8°.

Answer:
Looking at the given points we know that it is going to be rectangle because we have 4 points. Therefore the figure is a rectangle and the area formula would be [tex]A=l*w[/tex].
You can look at the attached graph and what we see is that our width of the rectangle is from [tex]y=-4[/tex] to [tex]y=3[/tex] which means that our height is 7 units wide. We can also see that our length starts at [tex]x=-1[/tex] and ends at [tex]x=4[/tex] making us have a length of 5 units.
We then plug in the values and solve
[tex]A = 7\ units * 5\ units[/tex]
[tex]A = 35\ units^2[/tex]
Therefore, the area of our rectangle is [tex]35\ units^2[/tex]

Answer:
not sure if this is correct but i tried (1267200 feet)

21120 ft
Step-by-step explanation:
We need to change 8 miles per hour to feet per minute
8 miles 5280 ft 1 hour

150 books are divided into 3 stacks. The 1st one has 30 more than the 2nd stack, 2nd stack has twice as many books in the 3rd stack. How many books are there in 3rd stack? (N represents the number of books in the 3rd stack.)
======================================================
Explanation:
N = number of books in the 3rd stack2N = number of books in the 2nd stack, since there are twice as many books here.2N+30 = add on 30 to the previous amount to get the number of books in the first stackIn other words,
1st stack = 2N+302nd stack = 2N3rd stack = NN is some positive whole number.
Add up all those expressions and set the sum equal to the 150 books total. Solve for N.
(1st stack) + (2nd stack) + (3rd stack) = total
(2N+30) + (2N) + (N) = 150
(2N+2N+N) + 30 = 150
5N + 30 = 150
5N = 150-30
5N = 120
N = 120/5
N = 24 which is the number of books in the 3rd stack
2N = 2*24 = 48 is the number of books in the 2nd stack.
2N+30 = 2*24+30 = 48+30 = 78 books in the 1st stack
Check:
1st+2nd+3rd = 78+48+24 = 150
The answer is confirmed.

Based only on the information given in the diagram, which congruence
theorems or postulates could be given as reasons why A DEF= AJKL?
Check all that apply.
D
O A. LL
B. HL
C. LA
D. ASA
E. SAS
OF. AAS
The option (C) LA and (D) ASA are correct because two angles and one side are the same.
What is the congruent triangle?Congruent triangles are those that are exactly the same size and shape. Congruent is represented by the symbol ≅ When the three sides and three angles of one triangle match the dimensions of the three sides and three angles of another triangle, they are said to be congruent.
From the triangle DEF and triangle JKL
∠D = ∠J (given)
∠F = ∠L (given)
ED = KJ (given)
∴ Triangle DEF and triangle JKL are congruent by the ASA
ΔDEF≅ΔJKL
Also:
∠F = ∠L (given)
ED = KJ (given)
ΔDEF≅ΔJKL by LA
Thus, the option (C) LA and (D) ASA are correct because two angles and one side are the same.
