I think it's supposed to be 200-3=? from what it looks like... the answer would be 197 if that is the case.

Step-by-step explanation:

Answer:

3-200= -197

Step-by-step explanation:

you can use a calculator, but you can also subtract 200 by 3 which equals 197. then add a negative sign to the left of the number :

The expression 4x^2-px-7 leaves a remainder of -2 when divided by (x-3). Then the value of p is 10.33

Given the expression is [tex]4x^2 - px - 7[/tex] leaves a remainder of -2 when divided by (x-3)

To find: value of p

x - 3 = 0

x = 3

Let [tex]g(x) = 4x^2 - px - 7[/tex]

Hence we can say,

g(3) = -2

Substitute x = 3 in g(x) we get,

[tex]g(3) = 4(3)^2 - p(3) - 7\\\\-2 = 4(3)^2 - p(3) - 7[/tex]

On solving we get,

-2 = 4(9) - 3p - 7

-2 = 36 - 3p - 7

3p = 36 - 7 + 2

3p = 31

[tex]p = \frac{31}{3} = 10.33[/tex]

Thus the value of p is 10.33

Answer:

No. if the length is 24 units and the width is 11 units, the perimeter would be p=48+22=70

Step-by-step explanation:

w=11 and l=24

P=2l+2w

P=2(24)+2(11)

P=48+22

P=70

The perimeter of the rectangle be 60 units when its width is 11 units and its length is 24 units; No. If the length is 24 units and the width is 11 units, the perimeter would be P = 48 + 22 = 70 units, not 60.

Its the sum of length of the sides used to made the given figure.

Given that the perimeter of a rectangle can be found using the equation P = 2L + 2W.

where P is the perimeter, L is the length, and W is the width of the rectangle.

Thus, w=11 and l=24

P=2l+2w

P=2(24)+2(11)

P=48+22

P=70

Hence, The perimeter of the rectangle be 60 units when its width is 11 units and its length is 24 units;

No. If the length is 24 units and the width is 11 units, the perimeter would be P = 48 + 22 = 70 units, not 60.

Answer:

The solution of the equation are x = - 1 , y = 0 and z = 3

Step-by-step explanation:

Given three linear equation as :

6 x - y + z = - 3        ......A

4 x - 3 z = - 13           ......B

2 y + 5 z = 15            ......C

Solving eq A and C

I.e 2× (6 x - y + z ) = -3 ×2

or, 12 x - 2 y + 2 z = - 6

So, ( 12 x - 2 y + 2 z ) + ( 2 y + 5 z) = - 6 + 15

Or,  12 x + 7 z = 9         ......D

Solving eq B and D

I.e 3 × ( 4 x - 3 z ) = - 13 × 3

or, 12 x - 9 z = - 39

So, (   12 x + 7 z ) - ( 12 x - 9 z ) = 9 + 39

or,  16 z = 48

∴   z = [tex]\frac{48}{16}[/tex]

i.e  z = 3

put the value of z in eq D

So, 12 x + 7×3 = 9  

Or, 12 x = 9 - 21

or,  12 x = - 12

∴   x = -  [tex]\frac{12}{12}[/tex]

I.e  x = - 1

Now, Put The value of z in eq C

or, 2 y + 5 z = 15    

or,  2 y + 5 × 3 = 15

Or,  2 y = 15 - 15

or,  2 y = 0  

∴  y = 0

Hence The solution of the equation are x = - 1 , y = 0 and z = 3  Answer

Step-by-step explanation:

Multiply 2 by itself three times, which gives you 8. Multiply 8 by itself twice, which gives you 64.

Tawa will multiply her initial 2 rocks by 3 in the first year, giving her 6 rocks.

In the second year, she multiplies the 6 rocks by 2, which results in a total of 12 rocks after two years.

To solve how many rocks Tawa will have after two years, we follow two steps of exponential growth.

Initially, she has 2 rocks.

After the first year, her collection will increase by a power of three, which means we will multiply 2 by 3 to find the new total:

2 rocks × 3 = 6 rocks.

After the second year, the number of rocks is going to increase by a power of two.

We then take the new total from the first year and multiply it by 2:

6 rocks × 2 = 12 rocks.

So after increasing her collection by a power of three in the first year, and then by a power of two in the second year, Tawa will have a total of 12 rocks

By setting up a system of equations to represent the mixing of solutions and the amount of alcohol present, we find that Teresa uses approximately 80 milliliters of Solution B.

In the lab, Teresa is mixing two solutions, A and B, with Solution A used 4 times as much as Solution B. Solution A consists of 17% alcohol and Solution B consists of 12% alcohol. In the question, we know that the resulting mixture contains 560 milliliters of pure alcohol. To find out how many milliliters of Solution B we need, we can set up a system of equations based on the given situation:

From these two equations, we can solve for x, which represents the amount of Solution B. This gives us x ~= 80 milliliters. This means Teresa uses approximately 80 milliliters of Solution B.

https://brainly.com/question/35467992

#SPJ2

Final answer:

To find the volume of Solution B that Teresa uses, we set up an equation using the given alcohol percentages and the total alcohol volume in the mixture. Solving the equation, we find that Teresa uses 700 milliliters of Solution B.

Explanation:

To solve this problem, we can use the concept of proportions and weighted averages to determine the quantity of Solution B. Let's denote the volume of Solution B as VB and therefore, the volume of Solution A is 4VB because we are given that Teresa uses 4 times as much Solution A as Solution B.

According to the alcohol percentages, we can write the following equations:

Solution A (17% alcohol): 0.17 × 4VB

Solution B (12% alcohol): 0.12 × VB

The total volume of alcohol in the resulting mixture is 560 milliliters, which is the sum of alcohol from both solutions:
0.17 × 4VB + 0.12 × VB = 560

Combining like terms, we obtain a single equation:
0.68VB + 0.12VB = 560

This simplifies to:
0.80VB = 560

Now, solving for VB:
VB = 560 / 0.80

After calculating, we get:
VB = 700 milliliters

Hence, Teresa uses 700 milliliters of Solution B.

Answer:

(7i-1)/5

Step-by-step explanation:

(4+2i)/(1-3i)

the opposite of 1-3i is 1+3i

multiply that

[(4+2i)(1+3i)]/[(1-3i)(1+3i)]

=[(4+2i+12i+6i^2)]/[(1-3i+3i-9i^2)]

=[(4+14i+6(-1))]/[(1-9(-1))]

=(4+14i-6)/(1+9)

=(-2+14i)/10

factor out the 2,

[-2(1-7i)]/10

-(1-7i)/5

(-1+7i)/5

(7i-1)/5

Remember that i^2=-1, because sqrt(-1)*sqrt(-1)=-1.

The commission that the salesperson earns on the sale is $1320

The commission would be double when he doubles his sales of furnaces

Step-by-step explanation:

The given is:

We need to find the commission that the salesperson earns

∵ The salesperson earns 4% commission on furnaces sale

∵ The furnaces sale have worth $33,000

- Find the 4% of 33,000

∴ The salesperson earns 4% of 33,000

∵ 4% × 33,000 = [tex]\frac{4}{100}[/tex] × 33,000 = 1320

∴ The salesperson earns $1320

The commission that the salesperson earns on the sale is $1320

∵ The salesperson doubles his sales of furnaces

∴ The commission would be double

That because the commission is a constant percent from his sales of furnaces, so if the amount of his sales of furnaces doubles , then his commission also doubles, it is a direct proportion relationship

Commission = constant (4%) × amount of furnaces sale

The commission would be double when he doubles his sales of furnaces

Equivalent ratios are those that when reduced yield the same value. Any ratios that when reduced become 4/7 are equivalent to the ratio 4 to 7. An example is 8 to 14.

In mathematics, two ratios are equivalent if the fractions they represent are equal. For your question, you are asked to find all ratios that are equivalent to the ratio 4 to 7. Essentially, you need to find ratios where when reduced will become 4/7 or we can upscale the values while maintaining proportions. For instance, if we multiply both numbers in the ratio 4 to 7 by 2, we get the ratio 8 to 14. These two ratios are equivalent because 4/7 = 8/14.
