can anyone please help me:)!​

Answer:

It is growth and the percentage increase is 46%

Step-by-step explanation:

The general form of an exponential function is;

Y = I(1 + r)^n

where Y is the present value, I is the initial, r is the growth or decay ratio, n is the number of times

To know if an exponential function is growth or decay, we need to know the repeating factor

If repeating factor is greater than 1, we have growth, if otherwise we have decay (less than 1).

As we can see in this case, we have r greater than 2, so what we have is growth

To get the percentage increase since it is growth, we equate;

1.46 = 1 + r

r = 1.46-1

r = 0.46 which is same as 46%

Answer:

x=4/7

Step-by-step explanation:

Change mixed fractions to improper fractions

2 1/4 = 9/4

1 2/7 =9/7

Therefore, we have

9/4=9/7÷x

9/7÷x is 9/7×1/x=9/7x

Then, we have

9/4=9/7x

Cross multipy

9×7x=9×4

63x=36

Make x the subject of the formula, we have

x=36/63

x=4/7

Answer:

£84.5

Step-by-step explanation:

Given ratio = 2:5:6

Amount that Louis got from the total amount = £39

Step 1: Add the ratio together

2+5+6=13

Step 2: covert the given ratio into fraction

George ratio=2/13

Charlotte ratio=5/13

Louis ratio= 6/13

✓LET THE AMOUNT THAT WAS SHARED AMONG THEM= Y

But we know that Louis got £39, then we can compute How much did they shared using "Louiz" shrare as

Louis ratio= 6/13 × Y= £39

= 6Y/13 = 39

Cross multiply

13×39= 6Y

507= 6Y

Y= 84.5

Hence, the amount they shared was £84.5

Answer:

x=109

Step-by-step explanation:

The angles inside of a triangle all add up to 180 degrees. So:

23+48+x=180

Simplify Like-Terms:

71+x=180

Subtract 71 from both sides:

x=109

The expression that represents Cindy's profit is $3.5b - $128.09.

Cindy's total profit is $30.82.

Profit is total revenue less total cost. Total revenue is the selling price per unit multiplied by the total units sold.

Profit = total revenue - total cost

($3.50b) - ($65.25 + $62.84)

$3.5b - $128.09

Profit for the first day = $3.5(24 + 15)  - $128.09

= ($3.5 x 39) - $128.09

= $136.50 - $128.09

=$8.41

Profit for the next day = $3.5(26 + 17)  - $128.09

= ($3.5 x 43) - $128.09

= $150.50 - $128.09

= $22.41

Total profit = $22.41 + $8.41 = $30.82

Step-by-step explanation:

Answer:50/100

Step-by-step explanation: 50/100 simplifies into 5/10, meaning they equal each other. 50 is half of 100, and 5 is half of 10.

Answer:

complet the squares

(x^2+14x)+(y^2+12y)=-60

add negative and positive 1/2 of linear coefs inside parenthaees

14/2=7, 7^2=49

12/2=6, 6^2=36

(x^2+14x+49-49)+(y^2+12x+36-36)=-60

factor perfect square

((x+7)^2-49)+((y+6)^2-36)=-60

get rid of parnthaeses

(x+7)^2-49+(y+6)^2-36=-60

(x+7)^2+(y+6)^2-85=-60

add 85 to both sides

(x+7)^2+(y+6)^2=25

It should be 125 as

BC=100

and it's four times the length of AB then

100/4=25

then 100+25=125

Answer:

what do u mean im confused

Step-by-step explanation:

Answer:

1) b and m

2) m∠8=m∠6

3) 160°

4)x=60°

Step-by-step explanation:

1) all straight lines sum to 180°

subtract the angles given from 180°

the other angle for b is 25°, while the other angle for m is 155°

so we can see that the angles for both lines are the same, hence they are parallel.

2) ∠8 should be the same as ∠6, ∠10 should be the same as ∠3, ∠7 same as ∠5 and ∠9 same as ∠4

in the options we are only given '∠8 should be the same as ∠6' as the correct answer, so we take that.

3) from the image we can see that both horizontal lines are parallel to each other, so both angles on the lines should be same, so ∠CET would be (2x-16)°

(2x-16)°+(7x+20)°=180°

we get x=20(nearest whole number)

∠CED=7x+20=7(20)+20=160°

4) since we need to show that they are parallel,

(2x+30)°=(4x-90)°

2x-4x=-90-30

-2x=-120

x=60

we then plug the x value into the two equations, in which we get 150° for both the angles [2(60)+30=4(60)-90] ⇒ (150=150)

I hope u understand it the way I put it.

Sorry if im wrong.

have a nice day

Answer:

arc BC=96 degrees

angle B=55 degrees

angle C=77 degrees

arc AB=154 degrees

(check: 48+55+77=180 and 110+154+96=360)

Step-by-step explanation:

angles A, B, & C are inscribed angles

angle A=1/2 arc BC

arc BC=96

since arc AC=110, then arc AB=360-110-96

arc AB=154

angle B=1/2(110)

angle B=55

angle c=1/2(154)

angle c=77
