The perimeter of a rectangle is 63cm. The length is 4cm more than its width. Find the dimensions of the rectangle

amm1812

O=63cm

a=b+4

O=2a+2b

O=2(b+4)+2b

O=2b+8+2b

63=4b+8

4b=63-8

4b=55

b=55/4=13.75

a=13.75+4=17.75

Answer: A)

B) 75%

C) She bought 1.5 dozen of plain bagels and 0.5 dozen of sesame bagels.

Step-by-step explanation:

Given: The ratio of the number of sesame bagels to the number of plain bagels is 1:3.

Let the number of sesame bagels be x and the number of plain bagels be 3x.

Then total bagels=x+3x=4x

A) The fraction of bagels are plain

B) The percent of bagels are plain

C) If ill bought 2 dozen bagels, the number of plain bagels

The number of sesame bagels

Hence, she bought 1.5 dozen of plain bagels and 0.5 dozen of sesame bagels.

your welcome ;)

The fracture strength of tempered glass averages 14.1 (measured in thousands of pounds per square inch) and has standard deviati

ololo11 [35]

Answer:

0.15866 is the probability of the average fracture strength of selected 100 pieces of glasses that of exceed 14.3.

Step-by-step explanation:

Given that, the strength of a tempered(x) a glass has average 14.1 and has standard deviation 2.

$\mu_x=14.1$ , $\sigma_x=2$

n=number of selected pieces= 100.

The probability that the average fracture strength of 100 pieces of this glass exceed 14.3 is

$P(\overline X>14.3)=P(\frac{\overline X-\mu_x}{2/\sqrt n}>\frac{14.3-14.1}{2/\sqrt{100}})$

$=P(\overline X>1)$

$=1-P(\overline X\leq 1)$

= 1 - 0.84134

=0.15866.

Which property was used to solve the given inequality?

Amiraneli [1.4K]

Subtraction Property of Inequality is used to solve the given inequality

Solution:

Given inequality is:

$y + 8 < - 8$

To solve the inequality, subtract 8 on both sides,

We know that,

Adding or subtracting the same quantity from both sides of an inequality leaves the inequality symbol unchanged

Also, by Subtraction Property of Inequality,

If you minus a number from one side of an inequality, you have to minus that same number from the other side of the inequality as well

$y + 8 < - 8\\\\\text{Subtract 8 from both sides of inequality }\\\\y + 8 - 8 < -8 - 8\\\\simplify,\\\\y$

Thus, Subtraction Property of Inequality is used
