Okay so 91x5=455
now try multiplying numbers to 455 until you get a number that is very, very close to 11,374
Try these numbers: 23,24,25
So, 23X455=?
24x455=?
25x455=?
Which one comes the closest to 11,374
That would be your answer.

Let C represent the blank
1. 91 · 5 (C) -1 = 11,374
2.               +1         +1
3.91<span> · 5 (C) = 11,375
4.  455 (C) = 11,375
5.  455/455 (C) = 11,375/455
6. 1 (C) = 25
7.  C = 25

Final Answer: 25</span>

I don’t understand number 89! please help I have a test tomorrow!
Rainbow [258]
V = rw

where; v = velocity , r = radius , w = angular speed

you're given the diameter = 0.5 miles so the radius = 0.25 miles

180 = (0.25)w
180/0.25 = w
720 radians per hour = w

2pi radians in 1 revolution

720 rad/hr * 1 rev / 2pi rad = 720/2pi rev/hr
= 114.6 rev/hr

Fabian harvests 10 pounds of tomatoes from his garden. He needs 225 pounds to make a batch of soup. If he sets aside 2.8 pounds
nadya68 [22]
He can make 3 batches of soup.

Starting with 10 pounds of tomatoes and taking out the number of pounds he sets aside for spaghetti sauce, 2.8, we have:
10-2.8 = 7.2 pounds left.

0.2 is read as "two tenths," so 7.2 = 7 2/10

We divide this remaining number of pounds by 2 2/5 for each batch of soup:

7 2/10 ÷ 2 2/5

Convert each to an improper fraction:
72/10 ÷ 12/5

Multiply by the reciprocal:
72/10 × 5/12 = 360/120 = 3

A guy wire 30 ft long supports an antenna at a point that is 24 ft above the base of the antenna.
GalinKa [24]
Use Pythagorean Theorem
c2 = a2 + b2
152 = a2 + 12
a2 = 152 - 122
=225 - 144 = 81
a = 9 ft
Distance from base of antenna = 9ft

Ainat [17]
No matter the number of times you rolled the dice, the probability of getting a number is always 1/6. But here we can choose 4 numbers ( 1 to 4) hence the probability P( 1 or 2 or 3 or 4) = 4/6 2/3  = 0.6667 = 66.67% (A)
