Marie would pay $1.50 because 200 grams is .2 Kg and you would multiply 7.50 by .2 and you'd get your answer

The correct answer is:

$1.50.

Explanation:

1 kg = 1000 g. We can set up a proportion to solve this:

7.50/1000g = x/200g

Cross multiply:

200(7.50) = x(1000)

1500 = 1000x

Divide both sides by 1000:

1500/1000 = 1000x/1000

1.50 = x

The LCM of two numbers is 36 their GCD is 3 one of the number is 9 find the other number

Aleks04 [339]

Answer:

Step-by-step explanation:

The LCM of 9 and x = 36

The GCD is 3, that means the number has to be divisible by 3 as well.

We can look at all the factors of 36, and see which numbers fit the description

36 = 1, 2, 3, 4, 6, 9, 12, 18, 36

1: Does not have a GCD of 3

2: Does not have a GCD of 3

3: Has a GCD of 9, but LCM is 3, not 36

4: Does not have a GCD of 3

6: Has a GCD of 3, but LCM is 18, not 36

9: Number is given

12: Has GCD of 3, and LCM is 36

18: Has GCD of 9

36: Has GCD of 9

The only number that works is 12, with a GCD of 3, and an LCM of 36

(a) Angela and Barbra decided to start a business together. Angela invested $24000 and Barbara invested

Gelneren [198K]

9514 1404 393

Answer:

(a) A : B = $9000 : $6000

(b) $1260

Step-by-step explanation:

(a) The investment ratio is ...

Angela : Barbara = 24000 : 16000 = 3 : 2

The profit of 15,000 goes 3/(3+2) = 3/5 to Angela, and 2/5 to Barbara:

Angela's share: (3/5)($15,000) = $9,000

Barbara's share: (2/5)($15,000) = $6,000

(b) We can multiply the ratio by $140 to see the larger amount:

4 : 9 = ($140)(4) : ($140)(9) = $560 : $1260

The larger share is $1260.

$2250 -1050 = $1200

Then the shares are ...

i. Sian: $2250

ii. Joanne: $1200

iii. Ratios: A : S : J = 105 : 225 : 120 = 7 : 15 : 8

To find the height h of a flagpole, Casey measured her own shadow and the flagpole’s shadow. Given that Casey’s height is 5 feet

Setler79 [48]

Answer:

The height of the flagpole is $25\ ft\ 4\ in$

Step-by-step explanation:

we know that

If two figures are similar, the the ratio of its corresponding sides is proportional

Remember that

$1\ ft=12\ inches$

Convert the measures in inches

$3\ ft=3(12)=36\ in$

$5\ ft\ 4\ in=5(12)+4=64\ in$

$14\ ft\ 3\ in=14(12)+3=171\ in$

$\frac{h}{64}=\frac{171}{36}\\ \\h=171*64/36\\ \\h=304\ in$

Convert inches into (feet + inches)

$h=304\ in=304/12=25.33\ ft=25\ ft\ 4\ in$

HLEP ME PLEASE!!! SEE PICTURE BELOW

Anastaziya [24]

We can find this answer by remembering the laws about opposite angles and their sums. We know that since 1 and 2 are opposite angles, they must be equal to each other. Therefore, we can set them equal to each other to solve for x.

Solving For x
x+5=6x-30
-x -x
5=5x-30
+30 +30
35=5x
/5 /5
7=x

Now that we know x=7, we can substitute that value in for x in the angle measurements.

Angle 1
x+5
7+5=12

Angle 2
6x-30
6*7-30=12

We know that we have the correct x-value because both angles are equal. Therefore, we know that the measure of both angles is 12 degrees.
