A survey of 70 people revealed the following information: 51 people are interested to consume wheat products, 55 people are interested to consume rice products and 48 are interested to consume both of the things.
(1) How many are interested in neither of these things?
(11) How many are interested to consume wheat products but not the rice products?
O a. (1) 11 are interested in neither of these things: (11) 4 are interested to consume wheat products but not the rice products,
O b. (1) 12 are interested in neither of these things: (11) 3 are interested to consume wheat products but not the rice products.
OC (1) 10 are interested in neither of these things: (11) are interested to consume wheat products but not the rice products
d. None

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
