Answer:

9/35

Step-by-step explanation:

Let x be the total trip distance.

Since Maria is assigned to drive 3/7 of the total trip, she is to drive 3x/7.

Now, since Maria has driven 3/5 of 3x/7, the amount of the total trip she has driven is 3/5 × 3x/7 = 9x/35.

So, Maria has driven 9/35 of the total trip.

Answer:

13 < y + x < 32

Step-by-step explanation:

x in (8,10) and y in (5,22) implies x + y in (8+5,10+22) = (13,32) so 13 < y + x < 32.

Answer:

14 < y+x < 31

Step-by-step explanation:

x = 9

y could be any number from 6 to 21

5+9 < y + x < 22+9

14 < y+x < 31

A. 8 is the answer

If the triangles are similar then their sides need to be in the same ratio. So, if 22 become 11, then the ratio is 2:1. So, for 16 it becomes 8.

Answer:

x = 8

Step-by-step explanation:

22/16 = 11/x

x = 11 . 16/22

x = 8

Step-by-step explanation:

3(x - 5) = 6

x - 5 = 2 (divide 3 on both sides)

x = 7 (add 5 on both sides)

The solution is x = 7.

3(x-5)=6

multiply 3 by x and -5

3x-15=6

add 15 on each side

it cancels out on the left nd on the right u get 21

so it would be

3x=21

divide by 3 on each side

X=7

Check:

3(7-5)=6

3(2)=6

Number 1

56.5 kaings each weighing 18.75 kilograms

56.5 × 18.75 = 1059.375 kilograms

Answer : 1059.375 kilograms

Number 2 (A)

$24.25 a kilo and 18.75 kilograms for one kaings

18.75 × $24.25 = $454.6875

Answer : $454.69

Number 2 (B)

$24.25 a kilo and 1059.375 kilograms

1059.375 × $24.25 = 25 689.84

Answer : $25 689.84

Number 3

1.5 kilograms free for each kaing

18.75 - 1.5 = 17.25 kg

17.25 kg × 56.5 kaings × $18 247.21875

Answer : $18 247.22

Answer:

(3, 7) is not a solution.

Step-by-step explanation:

In this question, we have to find out if the point (3, 7) is a solution to the equation.

To find your answer, you would plug in the coordinate into the equation and solve.

Solve:

y = 2x - 4

Plug in coordinate.

7 = 2(3) - 4

7 = 6 - 4

7 ≠ 2

Since both sides are not equal to each other, this makes the statement false. Therefore, (3, 7) is not a solution.

Your answer would be (3, 7) is not a solution.

Answer:

38

Step-by-step explanation:

Let x be the number of ten dollar

Number of five dollar=3x

Total amount of money in the cash register=$950

We have to find the number of ten dollar bill in the cash register.

According to question

[tex]5\times (3x)+10x=950[/tex]

[tex]15x+10x=950[/tex]

[tex]25x=950[/tex]

[tex]x=\frac{950}{25}[/tex]

[tex]x=38[/tex]

Hence, number of  ten dollar bills  in the cash register=38

Answer:

11943.31 mg

Step-by-step explanation:

460mg a day per kilo of weight, 4 doses for that total amount

460/4=115mg per kilo per dose

1 kilo = 2.205 pounds

115/2.205=52.15 approx mg per pound per dose

52.15*229=11943.31 approx, which is how much per dose

Answer:

Half of cord 24/2 = 12

Step-by-step explanation:

In the circle with r = 13 we have 13^2 = 12^2 + a^2 where a = the distance from the centre of this circle to the cord. Thus a = 5. Then the distance from the cord to the other circle centre is 21 - 5 = 16. In the second circle you can write r2^2 = 16^2 + 12^2. The r2 = sqrt (400) = 20

Answer:

-9

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

It says the sum of the two sides must be greater than the third side, so we can eliminate answers B and D.

Answer C uses 12 multiple times, but in a equation of a triangle, we can't use 12 twice because when you calculate using the Pythagorean Theorem, X has to be the square root of 44. So C is out.

A is the correct answer. (also, I got it right on edge 2021)

Answer:

The amount is $3372.13 and the interest is $872.13

Step-by-step explanation:

Interest is the monetary charge for the privilege of borrowing money.If $2,500 is deposited into a new account that earns 2% interest compounded quarterly and there are no other deposits or withdrawals,

then  864.671 is the interest earned after 15 years.

Interest is the monetary charge for the privilege of borrowing money.

Given that  $2,500 is deposited into a new account that earns 2% interest compounded quarterly and there are no other deposits or withdrawals, We need to find how much interest is earned after 15 years.

After 15 years,

Amount=2500×(1+2%)^15

=3364.671

The formula for interest is given below,

Interest=Amount-Capital

=3364.671-2500

=864.671

Hence 864.671 is the interest earned after 15 years for $2,500 is deposited with 2% interest compounded quarterly and there are no other deposits or withdrawals.

Answer:

[tex]105m^3/min[/tex]

Step-by-step explanation:

We are given that

Base side of square pyramid, a=3 m

Height of square pyramid, h=9m

[tex]\frac{da}{dt}=6m/min[/tex]

[tex]\frac{dh}{dt}=-1/min[/tex]

We have to find  the rate of change of the volume of the pyramid at that instant.

Volume of square pyramid, V=[tex]\frac{1}{3}a^2h[/tex]

Differentiate w.r.t t

[tex]\frac{dV}{dt}=\frac{1}{3}(2ah\frac{da}{dt}+a^2\frac{dh}{dt})[/tex]

Substitute the values

[tex]\frac{dV}{dt}=\frac{1}{3}(2(3)(9)(6)+(3^2)(-1)[/tex]

[tex]\frac{dV}{dt}=105m^3/min[/tex]

Hence, the rate of change of the volume of the pyramid at that instant=[tex]105m^3/min[/tex]

Answer:

No for the first one, yes for the second.

Step-by-step explanation:

Plug in the given numbers and see if it works.

15(1) + 3(4) = 10

15 + 12 = 10.

27 ≠ 10

Since 27 does not equal 10, we can already see that solution (1,4) will not work for these equations.

Now for the second problem, do the same thing.

10 = 1 + 9.

This is true, but remember to check the second equation just to be sure.

10 = 4(1) + 6

10 = 4 + 6

This is also true, so it (1,10) is a solution for the second system of equations.

Answer:

210 minutes

Step-by-step explanation:

First, we want to find out how many meters cubed of water there is, which is the volume.

The volume of this prism would be, the average of the two sides multiplied by 2 and 1.

1.5+0.6 = 2.1

2.1/2 = 1.05

1.05*2=2.1

2.1*1=2.1

2.1 meters is the volume but because it goes down by 30 cm, we have to convert 2.1 to cm.

2.1 * 100 = 210 cm.

Every 30 minutes, it goes down by 30 cm so:

210/30 = 7

210 minutes until it's empty
