A line that is parallel to y=3x+10 would have a slope of ______

Count by tens and ones to find the sum of 45+26

galben [10]

45+10= 55
55+10= 65
65+1= 66
66+1= 67
67+1= 68
68+1= 69
69+1= 70
70+1= 71

Because 10+10+1+1+1+1+1+1= 26,
71 is your answer :)

How Many times do at least 2 odd numbers show up when you count from 0 to 999? Show your work.

postnew [5]

let's count from 0 to 999

0, 1, 2, 3, ooh, look, there are 2 odd numbers, 4, 5, look another one, 6, 7, another!

we can see that every time you count from 0 to 999, at least 2 odd numbers show up

so answer is 1 time (because if 2 odd numbers or 20 odd numbers show up, it's still at least 2 odd numbers)

I think you really want to know how many times a pair off numbers occur together

like 33, 313 or 333, but not 31

that is interesting

in the first 10's 11 is only one

in each odd 10, in the 100's reigon, there is only 1 pair of odds

so 11, 33, 55, 66, 77, 99 or 6 pairs in the pre-100's zone

in the 100's zone, we have 101, 110-119, 121, 131, 141, 151, 161, 171, 181, 191 or 19 numbers with pairs of odds

in 200's, it's the same as pre-100's, 6 pairs

in the 300's zone, it's like 100's so 19 pairs

in the 400 zone, it's like 200's, 6 pairs

in 500's zone, it's like 100's, so 19 pairs

in the 600 zone, it's like 200's, 6 pairs

in 700's zone, it's like 100's, so 19 pairs

in the 800 zone, it's like 200's, 6 pairs

in 900's zone, it's like 100's, so 19 pairs

so a total of 6+19+6+19+6+19+6+19+6+19=125 pairs of odds

Why were pyramids important

Pyramids were important because they once housed the ancient Pharaohs and Queens. Hope this helped!

A manufacturer producing a new product, estimates the annual sales to be 9,600 units. Each year, 8% of the units that have been

Crazy boy [7]

Answer:

After n years, 120,000(1 - 0.92ⁿ) units, will be in use.

Step-by-step explanation:

Given;

estimated annual sales, a = 9600 units

determine common ratio, r;

$r = 1 - \frac{8}{100}\\\\r = 0.92$

sum of the units in use after n years is calculated by applying sum of nth term;

$S_n = \frac{a}{1-r} (1-r^n)$

$S_n = \frac{9600}{1-0.92} (1-0.92^n)\\\\S_n = \frac{9600}{0.08} (1-0.92^n)\\\\S_n = 120,000(1-0.92^n) \ units$

Therefore, after n years, 120,000(1 - 0.92ⁿ) units, will be in use.

B ABCD is a parallelogram and angle A< 90°. The height through the vertex D intersects the diagonal AC at point M. The height

kvv77 [185]

MBND is a parallelogram as BN=MD and BN║MD.

A parallelogram is a quadrilateral whose both pair of opposite side are equal and parallel. Few examples of parallelograms are square, Rhombus and rectangle.

Given ABCD is a parallelogram and ∠A=90°

Now we have to prove that MBND is a parallelogram

Given BN⊥AC and DM⊥AC

Since BN and DM are both perpendicular to the same straight line AC then we cam say that BN║DM.

Again we know from the properties of parallelogram that the diagonal divides a parallelogram into two equal triangles.

Therefore the diagonal AC divides the parallelogram into two equal triangles ΔABC and ΔADC.

Now we know that the area of a triangle is given by $\frac{1}{2}$ ×base ×height .

Area of ΔABC =Area of ΔADC

Since BN⊥AC and DM⊥AC

∴ $\frac{1}{2}$ ×BN×AC= $\frac{1}{2}$ ×DM×AC

This above equation can be simplified as

BN=MD

Hence BMND is a parallelogram as we know from the properties of parallelogram that when a pair of opposite sides are equal and parallel in a quadrilateral it is a parallelogram.
