Step-by-step explanation:

Answer 2
3x-2(-2x+5) = 4

3x + 4x - 10 = 4

7x-10 = 4

7x = 14

x = 2

y = -2(2) + 5

y = -4 + 5

y = 1

(x,y) = (2,1)

the 100th term of the sequence with the term -1-4n

Answers

Given:

The terms of a sequence are given by

[tex]a_n=-1-4n[/tex]

To find:

The 100th term of the sequence.

Solution:

We have,

[tex]a_n=-1-4n[/tex]

Putting n=100, we get

[tex]a_{100}=-1-4(100)[/tex]

[tex]a_{100}=-1-400[/tex]

[tex]a_{100}=-401[/tex]

Therefore, the 100th term of the given sequence is -401.

A square has legs of 11, what is the measure of its hypotenuse

A.) 9.4 or B.)15.6

Answers

15.6 is the measure of the hypotenuse of the square.

What is a square?

A square is a two-dimensional closed shape with 4 equal sides and 4 vertices.

Given that one side of the square is 11.

The diagonal is the hypotenuse of the square.

Since square have equal sides, the hypotenuse can be obtained using Pythagorean theorem.

i.e. 11² + 11² = (hypotenuse)²

i,.e. (hypotenuse)² = 121+121 =242

Therefore, hypotenuse = √242 = 15.6

Hence, the measure of the hypotenuse of the square is 15.6

On Monday Sylvia spent 5/12 of a day driving to her cousins house. On Friday she spent the same amount of time driving home. What fraction of a day did Sylvia spend driving to her cousins house and back?

Answers

Answer: The fraction of a day did Sylvia spend driving to her cousins house and back = [tex]\dfrac{5}{6}[/tex]

Step-by-step explanation:

Given: Fraction of day Sylvia spent to drive her cousins home = [tex]\dfrac5{12}[/tex]

Fraction of day Sylvia spent to drive her home back= [tex]\dfrac5{12}[/tex]

Total fraction of day Sylvia spend driving to her cousins house and back = [tex]\dfrac5{12}+\dfrac{5}{12}[/tex]

[tex]=\dfrac{5+5}{12}\\\\=\dfrac{10}{12}\\\\=\dfrac{5}{6}[/tex]

Hence, the fraction of a day did Sylvia spend driving to her cousins house and back = [tex]\dfrac{5}{6}[/tex]

jack finds this list of ingridents needed to make 20 muffins. To make 20 muffins you need 220ml milk, 250g castel sugar, 400g flour.
Jack has these ingridents : 1 litre of milk, 750g caster sugar and 1.5kg flour. Work out the greatest number of muffins Jack can make with his ingridents!

Answers

Answer:

60 muffins

Step-by-step explanation:

Find out how much ml you need for each ingredient.

20 muffins =

220 ÷ 20 = 11 (milk)

250 ÷ 20 = 12.5 (castel sugar)

400 ÷ 20 = 20 (flour)

Find out the greatest number of muffins Jack can make.

1 litre = 1000 ml

1000 ÷ 11 = 90.90 (recurring decimal) (milk)

750 ÷ 12.5 = 60 (castel sugar)

1500 ÷ 20 = 75 (flour)

Point VV is located at (-5,3)(−5,3) on the coordinate plane. Point VV is reflected over the yy-axis to create point V'V ′ . Point V'V ′ is then reflected over the xx-axis to create point V''V ′′ . What ordered pair describes the location of V''?V ′′ ?

Answers

Given:

Point V is located at (-5,3) on the coordinate plane.

It is reflected over the y-axis to create point V'.

Point V' is then reflected over the x-axis to create point V''.

To find:

The location of point V''.

Solution:

We have,

Point V= (-5,3)

If point V reflected over the y-axis, then

[tex](x,y)\to (-x,y)[/tex]

[tex]V(-5,3)\to V'(5,3)[/tex]

If point V' reflected over the x-axis, then

Mia deposited $2,500 in an account that earned simple interest annually. She did not make additional deposits; she did not make withdrawals.



At the end of 6 years, the balance was $3,025. What is the interest rate on this account?

Answers

The percent is 5.25%

The interest rate on Mia's account is 20.17%.

What is the simple interest?

The borrowing amount is just the principal amount multiplied by the simple interest rate.

Given, Mia deposited $2,500 in an account that earned simple interest annually. She did not make additional deposits; she did not make withdrawals.

The formula to calculate the simple interest is;

                                                 S.I. = P x T x R / 100 ,

Where S.I. is simple interest , P is principal amount, T is time period and R is interest rate in a year.

We have, P = $2500 T = 6 years, S.I. = $3025

Substituting all the values in the formula;

3025 = 2500 x 6 x R / 100

R = 3025 x 100 / 15000

R = 20.17%

Therefore, the interest rate is 20.17%.
