Answer:
x = 3 oz of seeds
y = 7 oz of seeds
Step-by-step explanation:
1. x + y = 10 oz (total amount of snack mix in ounces; oz)
2. $1.50x + $2.50y = $22 (how much the seeds and dried fruit costs)
3. Solve the system of equations using algebra.
$1.50 x + $1.50y = $15
$1.50 x + $2.50y = $22
There are $1.50x's in both of the equations, so cancel them out.
Subtract $2.50y by $1.50y and $22 by $15. y = 7
4. Plug in the y value in one of the equations.
x + 7 = 10; x = 3

From the observation deck of a skyscraper, Valeria measures a 67^{\circ} ∘ angle of depression to a ship in the harbor below. If the observation deck is 945 feet high, what is the horizontal distance from the base of the skyscraper out to the ship? Round your answer to the nearest hundredth of a foot if necessary.
The horizontal distance from the base of the skyscraper out to the ship would be 401.1 feet.
What are the trigonometric ratios?Trigonometric ratios for a right-angled triangle are from the perspective of a particular non-right angle.
In a right-angled triangle, two such angles are there which are not right angled(not of 90 degrees).
The slanted side is called the hypotenuse.
Let d the horizontal distance from the base of the skyscraper out to the ship. Since the angle of depression is 67°, hence:
Angle = 90 - 67 = 23°
Using trigonometric ratio:
tan(23) = d/ 945
d = 401.1 feet
The horizontal distance from the base of the skyscraper out to the ship would be 401.1 feet.

A school district planted maple trees and oak trees to make a school forest. The district planted 504 trees altogether. The district planted 11 times as many maple trees as oak trees.
How many maple trees did the school district plant?
Answer:
Number of maple trees planted = 462
Step-by-step explanation:
Let the number of oak trees planted be x.
Given,
The number of maple trees is 11 times the number of oak trees.
Therefore,
Number of maple trees planted = 11 * x = 11x
Total number of trees planted = Number of oak trees planted + Number of maple trees planted
504 = x + 11x
504 = 12x
x = 504/12 = 42
Number of oak trees planted = x = 42
Number of maple trees planted = 11x = 11 * 42 = 462

when x is 7???
Answer:
136
Step-by-step explanation:
Let's plug in 7 for x. 3(7)^2-2(7)+3. 7 to the second power is 49. 49*3 is equal to 147. 147-2(7) is 147-14, which is 133. 133+3=136, and therefore that is the answer.
Answer:
136
Step-by-step explanation:
substitute x = 7 into the expression
3x² - 2x + 3
= 3(7)² - 2(7) + 3
= 3(49) - 14 + 3
= 147 - 11
= 136

Malika models the volume of a popcorn box as a right rectangular prism and the box can hold 35 cubic inches of popcorn when it is full. Its length is 22 in and its width is 2 1/2 in. Find the height of the popcorn box in inches. Round your answer to the nearest tenth if necessary.
Answer:
To find the height of this prism, let's use the formula for the volume of a rectangular prism:
V = l · w · h
And this is what we know:
Volume = 35 cubic inches.Length = 22 inches.Width = 2 1/2 inches, simplified would be 2.5 inches.Now we are left to find the height, so plug in what we know into the formula I mentioned earlier:-
V = l · w · h
35 = 22 · 2.5 · h
Solve for 'h'!
35 = (22 · 2.5) · h
35 = 55 · h
35 = 55h
÷55 ÷55
35/55 = h
Which simplifies to:
7/11 = h, the height is 7/11 inches.
Double check;
V = l · w · h
V = 22 · 2.5 · 7/11
V = 35, which is correct!

Answer:
length = 12 mwidth = 6 mheight = 4 mStep-by-step explanation:
Let the height be x.
Length is 3 thrice the height, so length ⇒ 3xLength is twice the width, so width ⇒ 3x/2We know the formula for volume of the box.
V = lwhV = (3x)(3x/2)(x)288 = 9x³/29x³ = 576x³ = 64x = 4 mDimensions

What is a factorization?It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The steps involved in the factorization are;
1. For each pair of parentheses, we create a common factor.
2. We use x2 as a common factor for the first parenthesis.
3. We use common factor 3 for the second parenthesis.
[tex]x^3 + 11x^2 - 3x -33 \\\\ x^2(x+11)-3(x+11)_[/tex]
We will find the final solution as [tex]x^2(x+11)-3(x+11)_[/tex].
