Malachi bought n notebooks that cost $0.75 each and 12 pens that cost $0.50 each. If he spent a total of $32.25 how many notebooks did he buy? Write and solve the equation.

Answer:

16/49

Step-by-step explanation:

2/ 7÷ 7/8

Copy dot flip

2/7 * 8/7

Multiply the numerators

2*8 =16

Multiply the denominators

7*7 = 49

numerator over denominator

Answer:

The missing parts of the proof includes;

1) ∠ABC = m∠CBD + m∠ABD = 90° (Angle addition postulate)

2) m∠CBD = m∠ABD (Definition of angle bisector)

3) m∠CBD + m∠ABD  = m∠CBD + m∠CBD (Substitution property of equality)

Step-by-step explanation:

The given details of the proof are;

∠ABC is a right angle = 90°

Line DB is a bisector of ∠ABC

Therefore;

1) ∠ABC = m∠CBD + m∠ABD = 90° by angle addition postulate

By the definition of angle bisector, we have;

The angles formed by line DB from ∠ABC are equal,

2) m∠CBD = m∠ABD by the definition of angle bisector

3) m∠CBD + m∠ABD = 90° = m∠CBD + m∠CBD = 2 × m∠CBD by substitution property of equality

2 × m∠CBD = 90°

∴ m∠CBD = 90°/2 = 45°

Answer:

A: Given

B: measure the angle ABC = 90

C: angle addition postulate

D: 2 times the measure of angle CBD = 90

Answer:

We have ordered pairs (60,360), (120,720), (180,1080), (240,1440), and (300,1800) as the answer.

Step-by-step explanation:

The table would look like this:

Under minutes you would place 60, 120, 180, 240, and 300.

Under calories you would place 360, 720, 1080, 1440, and 1800.

y = 6x

Multiply 60, 120, 180, 240, and 300 by 6 for 6 calories.  This gives us the ordered pairs above.  

Answer:

Step-by-step explanation:

Slope is y2 - y1 / x2 - x1

x1= 1

x2= 0

y1=3

y2=-3

(-3-3) / (0-1) = -6/-1 = 6

Answer:

These two warehouses will contain the same number of boxes in 51 days.

Step-by-step explanation:

Since the number of boxes in Warehouse "A" currently totaling 476 is increasing at a rate of 4 boxes per day, while the number of boxes in Warehouse "B" currently totaling 986 is decreasing at a rate of 6 boxes per day, To determine in how many days these two warehouses contain the same number of boxes, the following calculation must be performed:

Warehouse A = 476 + 4X

Warehouse B = 986 - 6X

476 + 4 x 50 = 476 + 200 = 676

986 - 6 x 50 = 986 - 300 = 686

476 + 4 x 51 = 476 + 204 = 680

986 - 6 x 51 = 986 - 306 = 680

Therefore, these two warehouses will contain the same number of boxes in 51 days.

Answer:

π =14 cm

Step-by-step explanation:

Given:

circumference of a circle =616 cm

pie(π)=22/7

circumference of a circle=πr^2

616=22/7 *r^2

616*7/22 =r^2

4312/22 =r^2

196=r^2

[tex]\sqrt{196}[/tex] =r

Answer:

Nicole is now 15 years old

Christine is now 5 years old

Step-by-step explanation:

x = age Nicole

y = age Christine

x = 3y

x+5 = 2×(y+5) = 2y + 10

3y + 5 = 2y + 10

y + 5 = 10

y = 5

x = 3y = 3×5 = 15

0Answer:

Angle PTR is 136*

Step-by-step explanation:

In Question, We Have Given

Line PS and RS are Two Tangent To Circle With Centre T & ∠PSR=44* .

Thus ∠SPT=90* & ∠SRT=90* (Property Of Tangent ↔ Tangent always Form 90* With Radius Of Circle)  

Now We Have A Quadrilateral SPTR & The Sum Of All Angle Of Quadrilateral is 360* .

Thus The Angle Of PTR is

∠PTR = 360* - ( 90*+90*+44*)

∠PTR = 360* - 224*

∠PTR = 136*

Answer:

Step-by-step explanation:

Whole numbers

If the decimal is point 5 or greater you can round up.

If the decimal is less that point five you round down.

So your answer is 103

If you want to go to the nearest tenth

if the decimal is greater than 0.05 you round up

if the decimal is less than 0.05 you round down

If want the number to be to the nearest tenth and that's what you have, you leave it alone.

When we factor (7x + 6) (x + 1), we would go back to

7x² + 13x + 6

---------------------------------------------------------------------------------------------------------------

Have a great summer :)

Answer:

(7x+ 6 ) (x + 1  )

Step-by-step explanation:

7x^2 + 13x+6

This factors into

(7x+  ) (x +   )

They give us 6 in the first term  We know that the constant is 6  we need a 1 to make the constant to be 6

6*1 = 6

(7x+ 6 ) (x + 1  )
