What is 15% tip on a meal that costs $38.40

Mathematics
1 answer:
luda_lava [24]2 years ago
6 0

Answer:

5.76

Step-by-step explanation:

Easy way to work with percentage is to take the decimal and move it over one to the left and that will give you 10%.

Since you 38.40 move the decimal over one to the left and you'll get 3.84. That is 10%, but since you need 15% divide 3.84 by two to get 5%- that is 1.92.

3.84 (10%) + 1.92 (5%) = 5.76 (15%)

Taya2010 [7]

Answer:

The range is  { -1,3,7,11,15}

Step-by-step explanation:

The range is just the output values

f(-2) = 4(-2) +7 = -8+7 =-1

f(-1) = 4(-1) +7 = -4+7 = 3

f(0)= 4(0) +7 = 7

f(1) = 4(1) + 7 = 11

f(2) = 4(2) +7 = 8+7 = 15

Show that if u+v and u-v are orthognal, then the vectors u and v must have the same length.
pashok25 [27]

Answer with Step-by-step explanation:

We are given that

u+ v and u-v are orthogonal

We have to prove that u and v must have the same length.

When two vector a and b are orthogonal then

a\cdot b=0

By using the property

(u+v)\cdot (u-v)=0

We know that

(a+b)\cdot (a-b)=\mid a\mid^2-\mid b\mid^2

\mid u\mid ^2-\mid v\mid^2=0

\mid u\mid^2=\mid v\mid^2

Magnitude is always positive

When power of base on both sides are equal then base will be equal

Therefore,

\mid u\mid=\mid v\mid

Hence, the length of vectors u and v must have the same length.

Lucy is tiling her bathroom. She buys white and blue tiles in the
balandron [24]

Answer:

£289.20

Step-by-step explanation:

13:2 = x:16 or 13/2 = x/16

cross multiply: 208 = 2x

simplify: x = 104

16 blue tiles x £2.80 each = £44.80

104 white tiles x £2.35 each = £244.40

44.80 + 244.40 = £289.20
