21) Which expression is equivalent to 6(7x − 4)? A) 13x − 10 B) 13x − 24 C) 42x − 10 D) 42x − 24

Answer:

The Answer Is E!

Step-by-step explanation:

To solve this equation., you have to try every solution and the only one that perfectly completes both statements is answer E.

We subtract the $1.15 from $2.10 if this is the price of one taco, leaving the price of a small cup of coffees price     ($2.10-$1.15=$0.95 for a small cup of coffee

To check it fits both statements, we multiply the price of one coffee  by 3 ()$0.95×3=$2.85 for three small coffees\

Next, we multiply $1.15 (one taco) by 2 to fill in the expression  ($1.15×2=$2.30)

Finally, we add both the prices of the 3 coffees and two tacos which adds up to a perfect $5.15, justifying the answer

Answer:

$1057.3

Step-by-step explanation:

First we'll find the Interest no. 1, which is simple interest, assuming the time 1 year:

S.I= PRT/100

S.I= 780*5.2*1/100

S.I=$40.56

Now we'll find interest no.2, which is compound interest, time is 6 years, Principal amount (780) will remain the same as well as the rate thus (putting in the formula of compound interest- annual- [tex]A=P(1+\frac{R}{100} )^t[/tex]):

[tex]A= 780(1+\frac{5.2}{100})^6[/tex]

A= $1057.3

Answer:

a) 14.14 feet

b) 260.5 square feet

Step-by-step explanation:

A square has an area of 200 square feet.

a) How long is each side in simplest radical form?

Area of a square = (side length)²

Side length = √Area

Side length = √200 square feet

= 14.142135624 feet

≈ 14.14 feet

b) If I increase the length of each side by 2, what is the new area in simplest radical form?

= 14.14 feet + 2

= 16.14 feet

New area = (16.14 feet)²

= 260.4996 square feet

Approximately = 260.5 square feet

Answer:

1441.08 cubic inches

Step-by-step explanation:

Blue

V = L * W * H

L = 15

W = 9

H = 9

V = 9 * 9 * 15 =                       1215 CU IN

YELLOW

Diameter = 6

Height = 8

radius = d/2

radius = 6/2

radius = 3

Volume = pi*r^2 * h

Volume = 3.14*3^2 * 8

Volume =                                226.08    Add

Answer: 14 , 6

Step-by-step explanation:

Given

2 hammers and a screwdriver cost 34

1 hammer and 3 screwdrivers cost 32

Suppose the cost of the hammer is x and the cost of the screwdriver is y

[tex]\therefore 2x+y=34\quad\ \ldots(i)\\x+3y=32\quad \ldots(ii)[/tex]

Solving (i) and (ii) we get

[tex]x=14;y=6[/tex]

Thus, hammer cost 14 and screwdriver costs 6

Answer:

[tex]Perimeter =58[/tex]

Step-by-step explanation:

Given

[tex]AB = 24[/tex]

See attachment

Required

The perimeter of ABC

First, calculate the lengths of AC and BC.

From the attachment.

[tex]Ax = Az =10[/tex]

[tex]Cx = Cy = 5[/tex]

[tex]By =Bz[/tex]

So, we have:

[tex]AC = 10 + Cx[/tex]

[tex]AC = 10 + 5[/tex]

[tex]AC = 15[/tex]

Also:

[tex]Az + Bz = AB[/tex]

[tex]Az + Bz = 24[/tex]

Recall that: [tex]Ax = Az =10[/tex]

So:

[tex]10 + Bz = 24[/tex]

[tex]Bz = 24 - 10[/tex]

[tex]Bz = 14[/tex]

So, we have:

[tex]By = Bz = 14[/tex]

To calculate BC, we have:

[tex]BC = 5 + By[/tex]

[tex]BC=5+14[/tex]

[tex]BC = 19[/tex]

The perimeter is then calculated as:

[tex]Perimeter = AB + BC + AC[/tex]

[tex]Perimeter = 24 + 19 + 15[/tex]

[tex]Perimeter = 58[/tex]

Article -6

Description: coffee........ gunguli .

who is interested in statistics?

-karen riche at the French National institute of medical research ,whose work appears in journal neurology

who is the audience?

-7000 men's and women's in the three french cities.

what kind of decision one should make after reading this article?

reading the above article I came to acknowledge that women are only benefited as they don't metabolizes coffee in same way as men.so men should take more care and control over their coffee consumption than women.

Answer:

19.5°

Step-by-step explanation:

IN EFG the measure of G=90 DG=21 feet and EF=63 feet find the measure of E to the nearest degree.​

We solve the question using Sine rule

= a/sin A = b/sin B

= 21/sin E = 63/sin 90

Cross Multiply

Sin E × 63 = 21 × sin 90

sin E = 21 × sin 90/63

E = arc sin( 21 × sin 90/63)

E = 19.47122°

Approximately = 19.5°

Answer:

17 nickles !

Step-by-step explanation:

First, identify the variables:

n = amount of nickels

d = amount of dimes

Next, setup the equations based on what you know.  The first equation is:

n + d = 28

For the second equation, we know that a dime is worth 10¢ and a nickel is 5¢, so it should be:

0.05n + 0.10d = 1.95

This a three-step answer:

In one formula (you can use any of them; most people use the simplest one), single out the variable on one side

Apply the first formula into the second formula, and solve it to get the value of one variable

Apply the answer from the second formula into the first formula, and solve it to get the value of the other variable

======

Step One:

n + d = 28

n + d - d = 28 - d

n = 28 - d

Step Two:

0.05n + 0.10d = 1.95

(0.05 * (28 - d)) + 0.10d = 1.95

1.40 - 0.05d + 0.10d = 1.95

1.40 + 0.05d = 1.95

1.40 - 1.40 + 0.05d = 1.95 - 1.40

0.05d = 0.55

d = 11

Step Three:

n = 28 - d

n = 28 - 11

n = 17

======

Your answer should be 17 nickels and 11 dimes.

You can double check by applying the variables into both formulas.

n + d = 28

17 + 11 = 28

28 = 28

0.05n + 0.10d = 1.95

(0.05 * 17) + (0.10 * 11) = 1.95

0.85 + 1.10 = 1.95

1.95 = 1.95
