Answer:

200 notebooks

Step-by-step explanation:

Provided Information:

1) 8 out of every 500 notebooks contain a defect

2) 2500 notebooks are produced per day

We need to find out how many defective notebooks are produced per day:

1) 2500 ÷ 500 = 5

2) 8 x 5 = 40

Next we need to find out how many notebooks are defective per week:

1) 40 x 5 = 200 defective notebooks per week

Find the area of the shape shown below. I NEED HELP NOWWWWWW
Varvara68 [4.7K]

Answer:

<h2> 12.5 units{}^{2}</h2>

Step-by-step explanation:

Given figure : Trapezoid

Base sides,

a = 2.5

b = 7.5

Height ( h ) = 2.5

Now, finding the area:

\frac{1}{2} (a + b) \times h

Plug the values

=  \frac{1}{2 }  \times (2.5 + 7.5) \times 2.5

Calculate the sum

=  \frac{1}{2}  \times 10 \times 2.5

Reduce the numbers with G.C.F 2

= 5 \times 2.5

Calculate the product

12.5 \:  \:  {units}^{2}

Hope this helps...

Best regards!

1) Suppose a rhombus has 12 cm sides and a 30° angle. Find the distance between the pair of opposite sides.
Sergeeva-Olga [200]

Answer:

1) 6 cm

2) 117°

Step-by-step explanation:

1) Draw a picture of the rhombus.  The distance between opposite sides is the height of the rhombus.  If we draw the height at the vertex, we get a right triangle.  Using trigonometry:

sin 30° = h / 12

h = 12 sin 30°

h = 6 cm

2) Draw a picture of the rectangle.

∠KML is the angle the diagonal makes with the shorter side ML.  This angle is 54°.  ∠NKM is the angle the diagonal makes with the shorter side NK.  ∠KML and ∠NKM are alternate interior angles, so m∠NKM = 54°.

The angle bisector of angle ∠NKM divides the angle into two equal parts and intersects the longer side NM at point P.  So m∠PKM = 27°.

KLMN is a rectangle, so it has right angles.  That means ∠KML and ∠KMN are complementary.  So m∠KMN = 36°.

We now know the measures of two angles of triangle KPM.  Since angles of a triangle add up to 180°, we can find the measure of the third angle:

m∠KPM + 36° + 27° = 180°

m∠KPM = 117°

Please help me I don’t understand I have been working on this question for 14 minutes!!!m
ASHA 777 [7]

Answer:

<A = <B

=> 8x - 8 = 5x + 25

<=> 3x = 33

<=> x = 11

with x = 11 => mB = 5.11 + 25 = 55 + 25 = 80⁰
