3x^2-2x+3
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

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.

The length of a box is twice the width and thrice the height. If the volume of the box is 288 m then find the dimensions of the box
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
height = x = 4 mwidth = 3x/2 = 3(4)/2 = 6 mlength = 3x = 3(4) = 12 m4 + 6j + 5j - 5j.

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!
