If 3 x/4 +2 =56.8, what is the value of x?

A) x≈ −2.891
B) x≈ 6.708
C) x≈ −4.323
D) x≈ −2.059

Answer:

x=55°

Step-by-step explanation:

x=90-35

x=55°

(because its x+35=90°)

Answer:

The angle of x equals to be 45 degrees.

Step-by-step explanation:

Since the angle is a right angle that equals to 90. The you subtract 90 by your second angle, 35. 90 - 35 = 45

Answer:2/9

Step-by-step explanation:

Answer:

$5065.8332

Step-by-step explanation:

Given that :

Compound interest formula :

A = P(1 + r/n)^nt

t = period in years

n = number of compounding times per period, quarterly = 12/3 = 4

A = 5,993.79

r = 0.0307

t = 66 months = 66/12 = 5.5

5,993.79 = P(1 + 0.0307/4)^4*5.5

5,993.79 = P(1.007675)^22

5,993.79 = 1.1831795P

P = 5,993.79 / 1.1831795

P = 5065.8332

Hence, principal amount = $5065.8332

Answer:

  4.  1.3 cm³

  5.  621.2 mm³

  6.  116.5 m³

Step-by-step explanation:

The height to the peak of the pyramid is one side of the right triangle that has its hypotenuse equal to the slant height, and one leg equal to half the base side length. The Pythagorean theorem is used to find the height from the slant height (s) and the base length (b):

  h = √(s² -(b/2)²)

The volume is found from the formula ...

  V = (1/3)b²h

where b is the base length and h is the height found using the previous formula.

The tedious arithmetic is nicely done using a spreadsheet. Results are attached.

From the x-value of 3 to the x-value of 8, the y-value goes down from 3 to -6

Uh...I have no clue. Sorry. :(

Answer:

the volume is 50m^3

Step-by-step explanation:

The computation of the volume of the room is shown below:

As we know that

The Volume of the room = length × width × height

volume = 5m × 4m × 2.5m

= 50m^3  

Hence, the volume is 50m^3

Answer:

8.06 units  = AD

(just write sq rt 65 = 8.062 ) then write or try sq rt of 65  to 3 sf = nearest tenth 8.06 tenth units rounded.

Step-by-step explanation:

AE = 7

ED = 4

We use Pythagoras Theorem as it is a right angle as AE^2 + ED^2 = AD^2

7^2 + 4^2 = AD^2

49 + 16 = 65 sq rt

sq rt  65 = AD^2 = 8.062^2

AD = 8.062 units

Step-by-step explanation:

here's your solution

=> total money received by them = $1600

=> the given ratio are 7:5:4

=> let the ratio be X ,now

=> Maria = 7X

=> Carolina = 5X

=> Pedro = 4X

=> we know whole money = $1600

=> so, adding all

=>. 7x + 5x + 4x = $1600

=> 16x = $1600

=> x= $1600/16

=>. x = $100

now Maria = 7*100 = $700

Carolina = 5*100 = $500

Pedro = 4*100 = $400

Answer:

Step-by-step explanation:

The account value is given by the compound interest formula:

  A = P(1 +r/12)^n

Principal P invested at annual rate r compounded monthly for n months.

__

Using your parameters, the account balance would be ...

  A = $3000(1 +0.016/12)^66 = $3275.77 . . . account balance

The interest is the difference between this balance and the original investment amount:

  interest = $3000 -3275.77 = $275.77 . . . interest

Answer:

Step-by-step explanation:

Answer:

P = $ 482.00

Equation:

P = I / rt

Calculation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year,

then, solving our equation

P = 72.3 / ( 0.05 × 3 ) = 482

P = $ 482.00

The principal required to

accumulate interest of $ 72.30

on a rate of 5% per year for 3 years is $ 482.00.

Answer: To find the area of a trapezoid, start by adding together the length of the bases, which are the 2 sides of the trapezoid that are parallel with each other. Then, multiply that number by the height of the trapezoid. Finish by dividing the product by 2 to find the area. Or check this image it can help u

Step-by-step explanation:

Answer:

Subtract 5x from both sides of the equation.

7y=1−5x

x+4y=−5

Divide each term by 7 and simplify.

y=17−5x/7

x+4y=−5

Subtract x from both sides of the equation.

y=1/7−5x/7

4y=−5−x

y=1/7−5x/7

Divide each term by 4 and simplify.

y=1/7−5x/7

y=−5/4−x/4

y=1/7−5x/7

Answer:

When the discriminant value is zero, we get one real solution; When the discriminant value is negative, we get a pair of complex solutions; Standard Form. The standard discriminant form for the quadratic equation ax 2 + bx + c = 0 is. Discriminant, D = b 2 – 4ac. Where. a is the coefficient of x 2. b is the coefficient of x. c is a constant term.
