Answer:

  B.  9 cm

Step-by-step explanation:

The number of face masks Ray can make with 20 m of cord is ...

  (20 m)(100 cm/m)/(10.25 cm/mask) = 195.12195 masks

To make one more mask, he will need to buy an additional amount of ...

  (196 -195.12195)×(10.25 cm) ≈ 9.00 cm

Ray would need to add 9 cm of cord to his order.

$15, 300 a loan

Step-by-step explanation:

14, 400/2 = 7200

25000- 7200 = 17,800

17, 800- 2500 for a scholarship = 15,300

Answer:

????????????????????

Answer:

Step-by-step explanation:

9x + 2y = 59 -> 9x = 59 - 2y -> x = (59-2y)/9

2x + 5y = 4 -> 2(59-2y)/9 + 5y = 4 -> (118 - 4y)/9 +5y = 4

118 - 4y + 45y = 4*9 -> 41y = -82 -> y = -2, thus x = 7

Answer:

12 balls

Step-by-step explanation:

take 3 red balls ,5 green balls and 4 yellow balls that 12 balls = 6 balls in bag

If bag contains 4 white balls, 6 yellow balls, and 5 red balls then  6 balls can be chosen if there must be 2 balls of each color in 900 ways

Permutation is way of selecting and arranging things while combination is way of selecting things .

here, we have,

Given that  bag contains 4 white balls, 6 yellow balls, and 5 red balls

we have to select 6 balls

it's given that there must be 2 balls of each color

So here's how we can select them

2 white balls ,2 yellow balls and 2 red balls

So we have to select 2 white balls out of 4  white balls ,2 yellow balls out of 6 yellow balls and 2 red balls out of 5 red balls

so number of ways of selecting

4C2 * 2C2 * 5C2

=6*15*10

=900

If bag contains 4 white balls, 6 yellow balls, and 5 red balls then  6 balls can be chosen if there must be 2 balls of each color in 900 ways

Answer:

x=60

Step-by-step explanation:

I am going to try to explain this to the best of my abilities, but if you dont understand please let me know and I'll clarify. There is a straight ine tha that equals 180, so you do 180-120=60

Answer:

you dont divide it.

Step-by-step explanation:

x+8/2 can mean a few things cause its not very clear.

x+ 8/2

x+8/2 (x+8 over 2)

8/2=4 so if its x + 8/2 thats just x+4

Answer:

9.54 cm

Step-by-step explanation:

half base = 6:2 = 3 cm

height = [tex]\sqrt{equal side^2 - half base^2} = \sqrt{10^2 - 3^2} = \sqrt{100-9} = \sqrt{91}[/tex] = 9.54 cm

12x = (10)(11)

12x=110

Using a correlation Coefficient calculator, the correlation Coefficient, R value obtained is 0.7539

H0 : ρ = 0

H1 : ρ ≠ 0

The test statistic :

T* = r(√n - 2) / (√1 - r²)

T* = 0.7539 * √5 - 2) / (√1 - 0.7539²)

T* = 1.3057931 /0.6569891

T* = 1.988

Using the Pvalue from t statistic calculator :

T* = 1.988 ; df = 5 - 2 = 3

Pvalue = 0.0704

At α = 0.05

Pvalue > α ; we fail to reject H0 ; and thus conclude that and Y are not correlated. And conclude that X and Y are not correlated.

Answer:

y+5 = 9/5(x+3)

y - 4 = 9/5(x-2)

Step-by-step explanation:

First find the slope

m = ( y2-y1)/(x2-x1)

    = ( 4- -5)/(2 - -3)

    = ( 4+5)/(2+3)

    = 9/5

Then using the point slope form

y -y1 = m(x-x1)  where x1 and y1 are a point on the line

y -  -5 = 9/5(x- -3)

y+5 = 9/5(x+3)

or using the other point

y - 4 = 9/5(x-2)

Answer:

Step-by-step explanation:

logb a=c ------>  b^c =a

Answer:

It is true that 20% and 30% make 50%. But in the context of sale prices it is essential to keep track of the wholes to which these percents apply. For the backpack, the 30% discount applies to the original $60 price: 30% of $60 is 0.3×60=18 making the discount on the backback $18. So after using the coupon, the backpack price becomes $42. Emily's additional 20% coupon applies not to the original backpack price but to the discounted price of $42: 20% of $42 is $8.40. Emily would need to save an additional $12 off the $42 price in order to buy the backpack for $30 so her calculations are not correct.

As seen in part (a), Emily's coupon lowers the discount rack price by $8.40 so she will pay

42−8.40=33.60

or $33.60.

Answer:

0.02degrees

Step-by-step explanation:

Given the following

Length of the river (adjacent) = 1352km = 1352000m

Height of the source (opposite) = 453m

Required

angle of elevation theta

Using the SOH CAH TOA identity

tan theta = opposite/adjacent

tan theta = 453/1352000

tan theta = 0.0003351

theta = arctan(0.0003351)

theta = 0.02 degrees

Hence the Brazos river flows at an angle of 0.02degrees to the nearest hundredth
