❤️❣️❤️A jet flies 175 miles in 7 minutes. How far will the jet fly in 85 minutes?
Answer:
2125 miles
Step-by-step explanation:
Okay so to work this out we first need to find out how far the plane flies in one minute. To do this we do:
175 = 7
divide both sides by 7 to get 1 minute
25 = 1
The plane travels 25 miles in one minute.
Now to get 85 minutes we just do 25 x 85
25 x 85 = 2125
The plane travels 2125 miles in 85 minutes.
Hope this helps you :)
Answer:
First, we have to find the miles the jet flies in 1 minute. So we divide 175/7.
Multiply the quotient by 85. The answer will be the product, or miles a jet flies in 85 minutes.
Hope this helps!

A company rents out 15 food booths and 23 game booths at the county fair. The fee for a food booth is $125 plus $7 per day. The fee for a game booth is $65 plus $5 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.
Answer:
3,370 + 220d
Step-by-step explanation:
Food booth = 15
Game booth = 23
The fair lasts for d days
Cost of a food booth = 125 + 7d
Total cost of food booth = 15(125 + 7d)
= 1875 + 105d
Cost of a game booth = 65 + 5d
Total cost of game booth = 23(65 + 5d)
= 1495 + 115d
Total amount paid to the company = Total cost of food booth + Total cost of game booth
= (1875 + 105d) + (1495 + 115d)
= 1875 + 105d + 1495 + 115d
= 3,370 + 220d

4x2 − 6x + 5
4x2 + 6x − 5
4x3 − 6x2 + 5
4x3 + 6x2 − 5
Answer:
4x^2 + 6x - 5.
Step-by-step explanation:
Dividing term by term:
= 4x^2 + 6x - 5.
By Dividing 32x^3 + 48x^2 − 40x by 8x, we get 4x^2 + 6x - 5. Thus, option B is correct.
What is a quadratic equation?
A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
We have to Divide 32x^3 + 48x^2 − 40x by 8x.
32x^3 + 48x^2 − 40x
Take 8x common from each term
8x(4x^2 + 6x − 5)
Dividing term by 8x term:
8x(4x^2 + 6x − 5) / 8x
= 4x^2 + 6x - 5.
Thus, option B is correct.

Will this quadratic f(x)=14(x−16)−7 shift to the up or down?
Answer:
Down
Step-by-step explanation:
The formula for quadratic equations is [tex]f(x)=a(x-h)^{2}+k[/tex]. In this k controls the y-values, and therefore controls the vertical shifts. If k is negative then the quadratic will shift down. Since k is -7 in this equation it will shift down.
⦁ What is the arc length of an arc with radius 10 in and central angle of 60 degrees ? Show your work.
Let's see
L=
Ø/360×2πr60/360×2π(10)1/6×20π10/3π inThe arc length with central angle 60° and radius 10 cm is 10.47 cm.
Relation between angle and length of arc?An angle exists the figure formed by two rays, named the sides of the angle, sharing a common endpoint, reaching the vertex of the angle. Angles formed by two rays lie in the plane that includes the rays. Angles are also created by the intersection of two planes. These exist named dihedral angles.
If length of arc with central angle 360° is 2*[tex]\pi[/tex]*r (r-Radius)
Then length of arc with central angle 60° is [tex]\dfrac{2\pi r}{6}[/tex].
That is [tex]\pi[/tex]r/3 =3.14*10/3
=10.47 cm
Therefore, the arc length is 10.47 cm.

1. In a recent wind storm a large tree broke and made a 58° angle
between the two parts of the trunk. Which length below
is closest to the total length of the tree before the storm?
58°
14 ft
*see attachement for diagram
Answer:
40.4 ft
Step-by-step explanation:
Let the part that broke away be represented as "x"
Thus, the digram makes a right triangle shape.
The closest total length of tree before the storm = x + 14 ft
Apply trigonometric function to find x.
Reference angle = 58°
Side adjacent to reference angle = 14 ft
Hypotenuse = x
Apply CAH, which is:
Cos 58 = adj/hyp
Cos 58 = 14/x
x * Cos 58 = 14
x = 14/Cos 58
x = 26.4191188 ≈ 26.4 ft
✔️closest total length of tree before the storm = x + 14 ft = 26.4 + 14 = 40.4 ft
