Answer:

∠ C = 88°

Step-by-step explanation:

The opposite angles in a cyclic quadrilateral sum to 180°, then

8x - 4 + 7x + 4 = 180 , that is

15x = 180 ( divide both sides by 15 )

x = 12

Then

∠ C = 7x + 4 = 7(12) + 4 = 84 + 4 = 88°

​

Answers

Answer:

x = 39

Step-by-step explanation:

The angle between a tangent and the radius of a circle at the point of contact is 90° , then

x = 180 - (90 + 51) = 180 - 141 ←  angle sum of triangle

x = 180 - 141 = 39

x + 51 = 90

x = 90 - 51

x = 39°

triangle ABC has side lengths 8 inches, 17 inches, and 15 inches. Sofia uses the following steps to conclude that triangle ABC is not a right triangle.
[tex]a^{2} +b^{2} =c^{2} \\8^{2} +17^{2} =15^{2} \\64+289=225\\353\neq 225[/tex]

What mistake did Sofia make?

A Sofia made a calculation error.
B Sofia used the length of one of the legs as c when she should have used the length of the longest side as c.
C Sofia does not know if triangle ABC is a right triangle, so she cannot use the Pythagorean Theorem or its converse.
D Sofia’s conclusion is incorrect. When the sides of a triangle do not satisfy a2+b2=c2, you cannot conclude that the triangle is a right triangle.

the length of a rectangle is 7 cm more than its width and the area is 30 cm find the length, width and the perimeter

Answers

Answer:

Step-by-step explanation:

let width=x

length=x+7

x(x+7)=30

x²+7x-30=0

x²+10x-3x-30=0

x(x+10)-3(x+10)=0

(x+10)(x-3)=0

either x=-10 (rejected being negative)

or x=3

width=3 cm

length=3+7=10 cm

Perimeter=2(10+3)=2×13=26 cm

In a random sample of 200 customers at a restaurant, 140 customers ordered french fries. If the restaurant typically has 1,000 customers in a day, about how many will probably order french fries?

Answers

Answer: 700 customers

Step-by-step explanation:

In a random sample of 200, 140 people ordered French fries.

Find out the percentage of people who ordered French fries:

= 140 / 200

= 70%

If the restaurant usually has 1,000 customers a day, based on the rate of people who ordered French fries out of 200 people - 70% - the number of people who will probably order French fries are:

= 70% * 1,000

= 700 customers

We sell ice cream at a retail store, which we operate 50 weeks per year. Whenever we order from our supplier we incur a $250 ordering charge. Customer demand is 200 pounds per week and it costs us $35 per pound per year to hold the ice cream in proper storage. a) What is the EOQ?

Answers

Answer:

the EOQ is 378 units

Step-by-step explanation:

The computation of the economic order quantity(EOQ) is shown below:

EOQ is

[tex]= \sqrt{\frac{2\times A\times O}{C} } \\\\= \sqrt{\frac{2\times 200 \times 50\times \$250}{\$35} }[/tex]

= 378 units

Here A represent the annual demand

O represent the ordering cost

And, C represent the carrying cost

hence, the EOQ is 378 units
