Mathematics

LenKa [72]3 years ago

Answer:

NO unless you know the value of m you are able to subtract a variable form a constant unless the constant is attached to the same variable. For example you can sub tract 7m-m and that would equal 6m but you can not subtract 7b-m because the variables are different. If you tink about it this way 7 can have the variable A attached to it to make it 7a and the variable m can be thought of as 1m. Therefor you can not have 7a-1m because the variables are different.

30. Tina went to batting cages with $20. She rented a bat for $3. 25 and
aliya0001 [1]

Answer:

5

Step-by-step explanation:

Tina started with $20, but had to spend $3.25 on the bat.

$20-$3.25 = $16.75, which is all she has left for rounds.

Each round costs $3.00

$16.75 divided by $3.00 comes out to 5.58 rounds, but since she can't play 1/2 a round, that means she could only play 5 rounds

5 rounds X $3.00 per round comes to $15.00

Answer:

C. 4yd * 3ft/yd * 12in/1ft * 2.54cm/1.in = 365.76cm

Step-by-step explanation:

First you change 4 yards into feet (By multiplying the 4 yard by 3 ft/1yd)

then you convert 12 feet into inches (By multiplying the 12 feet by 12in/1ft)

after you convert 144 inches to cm (By multiplying the 144 in by 2.54 cm/1in)

you’ll have the value in cm. Which is 365.76.

Solve 19cos θ = 5 cos θ + 14 for all values of θ if θ is measured in radians.
Bas_tet [7]

Answer:

Ф=xπ, x={0,+∞}

Step-by-step explanation:

be 19cosФ=5cosФ+14 → 19cosФ-5cosФ-14 → 14cosФ-14=0 → cosФ=1

then,  values for which cosФ=1 are Ф=0º=360º=720º........., but the values of Ф  must be radians, so Ф=xπ, where x∈Z, not including the negative numbers,

x={0,1,2,3,....∞}

Note: π≅3.141592

when calculating the values, it must be done in radian mode
