4 and 8/9 - 1 and 4/5

Mathematics
2 answers:
prohojiy [21]4 years ago
8 0

First, turn both fractions into improper fractions.

4 8/9 = 44/9

1 4/5 = 9/5

Second, find common denominators.

44/9 = 220/45

9/5 = 81/45

Third, subtract.

220/45 - 81/45 = 139/45

Fourth, simplify.

139/45 = 3 4/45

Best of Luck!

Answer:

Step-by-step explanation:

4\frac{8}{9}-1\frac{4}{5}\\=\frac{44}{9}-\frac{9}{5} \\=\frac{44*5-9*9}{y} \\=\frac{220-81}{45} \\=\frac{139}{45} \\=3\frac{4}{45}

Use the work shown to find the solutions of the quadratic equation. x2 – x –3/4=0 x2 – x = 3/4
bija089 [108]

Answer:

x = - \frac{1}{2}, x = \frac{3}{2}

Step-by-step explanation:

Given

x² - x - \frac{3}{4} = 0

Multiply through by 4 to clear the fraction

4x² - 4x - 3 = 0

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 4 × - 3 = - 12 and sum = - 4

The factors are + 2 and - 6

Use these factors to split the x- term

4x² + 2x - 6x - 3 = 0 ( factor the first/second and third/fourth terms )

2x(2x + 1) - 3(2x + 1) = 0 ← factor out (2x + 1) from each term

(2x + 1)(2x - 3) = 0

Equate each factor to zero and solve for x

2x + 1 = 0 ⇒ 2x = - 1 ⇒ x = - \frac{1}{2}

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = \frac{3}{2}

A circle has a diameter of 121 inches. Which equation can be used to find the radius of this circle? r=121/2π r=1/2(121) r=121π
drek231 [11]
The radius of a circle is always half its diameter.

Therefore the radius of a circle with a diameter of 121 inches is 1/2(121).

Hence, the correct answer is r = 1/2 (121)

A diver is standing on a platform 24 feet above the pool. He dives form the platform with an initial upward velocity of 8 feet p
Mazyrski [523]

Answer:

It should be t = 1.5 seconds  if your equation is  h(t)  = -16*t^2 + 8t + 24

Step-by-step explanation:

h(t)  = -16*t^2 + 8t + 24

We want  to solve for t when h(t) = 0.

This is a parabolic equation so basically we can use the quadratic formula to solve this.

h(t)  = -16*t^2 + 8t + 24

0 = h(t)  = -16*t^2 + 8t + 24

take out the 8

0 = -2t^2 + t + 3

0 = -2t*t  - 2t  + 3t + 3

0 = -2t * (t + 1)  +  3*( t + 1)

0 = (-2t + 3) * ( t + 1)

so time cannot be negative, so we choose  0 = (-2t + 3),   t = 3/2 seconds

or  t = 1.5 seconds

Find the measure of MNQ
xz_007 [3.2K]

Answer:

m∠MNQ = 158

Step-by-step explanation:

As it can be seen in the figure:

+) The measure of arc MQ = 91 degree

+) The measure of arc RP = 225 degree

As this is the circle, four points M, Q, P and R are on the circle, so that we have:

+) m∠RMP = 1/2. measure of arc RP = 1/2 x 225 = 112.5 degree

As N is on MP

=> m∠RMN = m∠RMP = 112.5

+) m∠ MRQ = 1/2 measure of arc MQ = 1/2 x 91 = 45.5 degree

As N is on RQ

=> m∠MRN = m∠MRQ = 45.5

In the triangle RMN, the total measure of 3 internal angles is equal to 180 degree, so that:

m∠MNR + m∠RMN + m∠MRN = 180

=> m∠MNR + 112.5 + 45.5 = 180

=> m∠MNR  = 180 -112.5 -45.5 = 22

As N is on QR

=> m∠MNR + m∠MNQ = 180

=> m∠MNQ = 180 - m∠MNR  = 180 - 22 = 158

So that m∠MNQ = 158
