The length of a rectangle is 9 cm more than its

arlik [135]

= 4 = x²

x = Answer: Length= 11 , Brteadth = 2

Step-by-step explanation: Let the breadth of the rectangle be x

length = 9 + x

area = 36 cm²

A.T.Q

36cm² = 9x*x

36 = 9x²

36/9 = 4 = x²

x = root of 4

x= 2

Therefore , breadth of rectangle is 3cm and length is 12 cm

verification:

l*b = 12*3 = 36cm²

Verify that :- 5/8x(7/9-11/6)=(5/8x7/9)-(5/8x11/6) please answer

LuckyWell [14K]

The distributive law states that a(b - c) = ab - ac
In this example a = 5/8, b = 7/9 and c = 11/6

Help please!!! Thank you

Answer:

136

Step-by-step explanation:

Formula for area of a trapezoid = $A=\frac{a+b}{2} h$

where a and b = bases and h = height

The trapezoid has the following dimensions

Base 1 = 12 cm

base 2 = 22 cm

Height = 8 cm

Using these dimension, we plug in the values into the formula

$A=\frac{12+22}{2} 8\\12 +22=34\\\frac{34}{2} =17\\17*8=136\\A=136$

Hence, the area of the trapezoid is 136cm²

Many states assess the skills of their students in various grades. One of the tests provided by a national association assesses

Alik [6]

Answer:

95% of these scores are between 210 and 362.

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 286, Standard deviation = 38

Use the 68-95-99.7 rule to give a range of scores that includes 95% of these students.

This is within 2 standard deviations of the mean. So

286 - 2*38 = 286 - 76 = 210

286 + 2*38 = 286 + 76 = 362

95% of these scores are between 210 and 362.
