Volunteers at Sams school use some of the student councils savings for a special project.They buy 4 backpacks for $9 each and fill each backpack with paper and pens that cost $5.By how much did the student councils savings change because of this project?

Answers

Answer: The student councils savings change by $41.

Step-by-step explanation:

Number of backpacks = 4

Cost of each backpack = $9

Paper and pen costs = $5

Total spending = (Number of backpacks ) x (Cost of each backpack ) + (Cost of paper and pen)

= $ (4 x 9 +5)

= $ 41

Hence, the student councils savings change by $41.

Prove that:
[tex] \tan(165) = \sqrt{3} - 2[/tex]
Please solve this question.​

Answers

Answer:  see attachment

Step-by-step explanation:

Given: cos 330 = √3/2

Prove that tan (165) = √3 - 2

Step-by-step explanation:

cos330° = cos(360° - 30°) = cos(2π - 30°)

Using, cos(2π - x) = cosx, x < 90°

=> cos(2π - 30°)

=> cos(30°)

=> √3/2 , proved

(ii): tan(165°) = tan(180° - 15°) = tan(π - 15°)

Using, tan(π - x) = - tanx

=> tan(π - 15°)

=> - tan15°

=> - (-√3 + 2)

=> √3 - 2 proved

For tan15° :

Using, tan2x = 2tanx/(1 - tan²x)

tan30° = 2tan15°/(1 - tan²15°)

1/√3 = 2tan15° / (1 - tan²15°)

1 - a² = 2√3 a {a = tan15°}

Solving this we get, a = -√3±2

As a = tan15°, it can't be -ve, thus

a = tan15° = -√3 + 2

If a.b=0, then a=0 or b=0

The equation

(m-10)(6m-1)=0

Answers

Answer:

1st number: 0

2nd number: 17

Step-by-step explanation:

3x+2y=34 x is the first number, y is the second.

1/2x+2y=34 multiply each number by two to get rid of the integer by the variable x.

x+4y=68 solve for x.

x=68-4y add this into the first equation to solve for variable y.

3(68-4y)+2y=34 solve for y.

204-10y=34

-10y= -170

y=17

now to solve for x

x= 68-4(17)

If an object is projected upward with an initial velocity of 48 ft per second from a height h of 64 ft, then its height t seconds after it is projected is defined by the equation f(t) = -16(t) with superscript (2) + 48t + 64. How many seconds after it is projected will it hit the ground?

Answers

Answer:

4 seconds

Step-by-step explanation:

Given that :

Height of a projected object is modeled by:

f(t) = - 16t² + 48t + 64

t = height

How many seconds after projection will it hit the ground ;

When the projectile hits the ground ; t = 0

f(t) = - 16t² + 48t + 64

f(t) = 0

- 16t² + 48t + 64 = 0

Divide through by - 16

t² - 3t - 4 = 0

t² - 4t + t - 4 =0

t(t - 4) +1(t - 4) = 0

(t +1) = 0 or (t - 4) = 0

t = - 1 or t = 4

t can't be negative ;

Hence, the projectile will hit the ground after 4 seconds

Convert the following repeating decimal to a fraction in simplest form.
.72

Answers

Answer:

The real answer is 8/11

Step-by-step explanation:

The fractional value of 0.72 is 18/25.

What is Decimal?

A decimal is a number with a whole and a fractional part. Decimal numbers are between integers and represent numerical value for whole plus some fraction of a whole.

A decimal number comprises two parts: a whole number component and a fractional component. The decimal place value system is the same as the whole number value system for the whole component of a decimal number.

Given:

We have the decimal number 0.72.

Now,  we can remove the decimal and put the number of zeroes in the denominator.

So, 0.72

= 72/100

Now, simplifying the fraction as

= 36/ 50

= 18/25

Now put decimal point ahead of two number from the numerator.

So, 37/100 = 0.37

So, the decimal is 0.37.
