Answer:

Hannah = 20, Sal = 4

Step-by-step explanation:

Total number of sweets = 24

Ratio in which the sweets was shared;

Hannah : Sal = 5 : 1

Hannah gets:

Hannah = 5 / ( 5+1)  * 24 = 5/6  * 24 = 5 * 4 = 20

Sal gets:

Sal = 1 / ( 5+1)  * 24 = 1/6  * 24 = 1 * 4 = 4

Answer:

For 3x + 5y = -13 the answer is x= -13/3 + 5y/3

and for 2x + 15y=3 the answer x= 1.5 + (-15y/2)

Step-by-step:

For 3x+5y=-13 you have to add 5y on both sides. Then you have to divide by 3 on both sides and cancel out the common factor of 3. Then you would get x= 13/3 + 5y/3.

For 2x + 15y=3 you have to subtract 15y on both sides of the equation. You should have 2x=3 + (-15y). Then divide by 2 on both sides. 3 divided by 2 is 1.5 and -15y divided by 2 is -15y/2 since 2 doesn't have the same variable. so the answer should be x= 1.5 + (-15y/2).

Answer:

h=3y+9

Step-by-step explanation:

We will write an expression using the y=mx+b format.

3 is the rate at which the three grows, y will represent any given year.

9 is the starting rate, or your y intercept.

Answer:

h=3y+9

Step-by-step explanation:

let h represent the height of the tree

h=3y+9

Hello your question is incomplete attached below is the missing part of the  question

answer :  ( d / D )  =  [tex]n_{a}[/tex]

                                 [tex]n_{w}[/tex]

Step-by-step explanation:

Given data:

Apparent distance = distance calculated using angle ∅a

also applying the approximation ; sin(x) ≈ x  and  asin(x) ≈ x

Find the ratio of apparent distance to real distance (d / D )

Using the given data in the question the ratio of apparent distance to real distance ( d / D )  =  [tex]n_{a}[/tex]

                                 [tex]n_{w}[/tex]

where [tex]n_{a}[/tex] = index of refraction ( air )

           [tex]n_{w}[/tex] = index of refraction ( water )

Step-by-step explanation:

We need to do LCM in this case.

2_|_ 6,4,16

2 _|_ 3,2,8

_|_ 3, 1,4

It is not divisible further.

So, LCM is 2×2×3×4 = 48

So, 48 is the answer.

Hope it helps :)

Answer:

answer should be 105 degrees.

Step-by-step explanation:

this is becuase the 75 degree angle given creates a 105 degree angle to its left. and the car turning left onto 3rd street would be a corresponding angle to the 105 degree angle on the top. sorry if its confusing, but the answer is 105 degrees. hope it helps

Answer:The angle formed by turning from traveling southwest on King Avenue to 3rd street is a corresponding angle to the 75° angle. This means its measure is 75°. here is your answer!

Step-by-step explanation:

To calculate the distribution, we have the following values;

p = 35% = 35/100 = 0.35

q = 1-p = 1-0.35 = 0.65

n = 7

Answer:

p = 0.35

Equation: 160 + 3x = 195 - 2x

Solution: 7 weeks

Step-by-step explanation:

x is going to stand for the number of weeks

Nick:

160 + 3x

Adam:

195 - 2x

Equation: 160 + 3x = 195 - 2x

Solution: 7

They would weigh 181 pounds

The equation to find when Nick and Adam will weigh the same amount is

160 + 3w = 195 - 2w

It will take 7 weeks for Nick and Adam to weigh the same amount.

After 7 weeks, Nick and Adam will both weigh 181 pounds.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

a.

Let w be the number of weeks, then the equation to find when Nick and Adam will weigh the same amount is:

160 + 3w = 195 - 2w

b.

To solve for w, we can simplify the equation:

160 + 3w = 195 - 2w

5w = 35

w = 7

c.

To find how much Nick and Adam will weigh after 7 weeks, we can plug w = 7 into either of the original equations:

Nick's weight = 160 + 3w = 160 + 3(7) = 181 pounds

Adam's weight = 195 - 2w = 195 - 2(7) = 181 pounds

Thus,
The equation to find when Nick and Adam will weigh the same amount is

160 + 3w = 195 - 2w

It will take 7 weeks for Nick and Adam to weigh the same amount.

After 7 weeks, Nick and Adam will both weigh 181 pounds.

Answer:

[tex]X=\$519.48[/tex]

Step-by-step explanation:

From the question we are told that

Loan 1 [tex]X_1=\$400[/tex]

Loan 1 due [tex]t_1=95days[/tex]

Loan 2 [tex]X_2=\$700[/tex]

Loan 2 due[tex]t_2=0days[/tex]

Payment [tex]Y=\$600[/tex]

Worth of money [tex]w=6\%[/tex]

Payment due [tex]t=30days[/tex]

Focal date [tex]t_f=125days[/tex]

Generally [tex]\$400[/tex] was due 95days ago

Therefore

[tex]125+90=220days[/tex](total days to consider)

Therefore

[tex]300+400 =700[/tex] is due today

125days left

Given

600 due in 30days

[tex]125-30=95days[/tex]

Generally the Final payment is mathematically given by

[tex]400(1+ 0.06*\frac{220}{365} ) + 700(1+0.06*\frac{125}{365} )=600(1+0.06*\frac{95}{365} )+X[/tex]

[tex]X=1128.9692 - 609.3698[/tex]

Therefore the

Answer:

LN = 4.326

Step-by-step explanation:

dropping a perpendicular from point k to LM

call that point on line LM, point X

angle KLM = 47 degrees so angle NKL = 28 degrees

sin 47 = KX/8.9

KX = 6.509

angle LKX = 90-47-28 = 15 degrees

tan 15 = XN/6.509

XN = 1.744

cos 47 = XL/8.9

XL = 6.070

XL-XN=LN

LN = 6.070-1.744 = 4.326

Answer:

Step-by-step explanation:

2, -3 , -8 , -13 , - 18 .............

This is an arithmetic sequence.

First term = a = 2

Common difference = Second term - first term

                                 = -3 - 2 = -5

Nth term = a + (n - 1)*d

               = 2 + (n - 1)*(-5)

               = 2 + n*(-5) - 1 *(-5)

               = 2 - 5n + 5

             = 7 - 5n

n = 19,

19th term = 7 - 5*19

               = 7 - 95

               = - 88

n = 21,

21st term = 7 - 5*21

               = 7 - 105

               = -98
