Percent increase and decrease. Original number:45 New number: 18

Mathematics
1 answer:
andre [41]3 years ago
4 0

Answer:

60% decrease

Step-by-step explanation:

To find the percentage increase/ decrease construct a fraction with numerator showing increase/ decrease and denominator with original number then multiply the fraction by 100%

here the decrease = 45 - 18 = 27

percent decrease = \frac{decrease}{original} × 100%

                             = \frac{27}{45} × 100% = 60%

Find the value of x...X=?
Romashka [77]

Answer:

The value of  x° = 134°

Step-by-step explanation:

Given the angles of a quadrilateral

  • 100°
  • 51°
  • 75°
  • x°

We know that the sum of interior angles in a quadrilateral is 360°.

so

100° + 51° + 75° + x° = 360°

226° + x° = 360°

subtracting 226° from both sides

226° + x° - 226°  = 360° - 226°

x° = 134°

Therefore, the value of  x° = 134°

VERIFICATION:

100° + 51° + 75° + 134° = 360°

360°= 360°

Choose the correct simplification of the expression (2ab5)3. (1 point) Question 8 options: 1) 8ab15 2) 8a3b8 3) 5a3b15 4) 8a3b15
d1i1m1o1n [39]

Answer:

4). 8a^{3}b^{15}

Step-by-step explanation:

The Given expression is that,

(2ab^{5})^{3}

On simplifying,

(2ab^{5})^{3} = (2ab^{5} )(2ab^{5}) (2ab^{5})

= (2^{3} ) * (ab^{5})^{3}

= (2×2×2) × (ab^{5} × ab^{5} × ab^{5})

= 8a^{3}b^{15}

Thus, <u>option 4</u> i.e.  8a^{3}b^{15} is the correct simplification of the given expression.
