Answers

Answer and Step-by-step explanation:

Essentially, the figure FEHG got scaled by a factor of 1.5, and turned into BADC

So 2.4 times 1.5 is 3.6

3.6 = x

Hope this helps! #teamtrees #WAP (Water And Plant)

Answer:

The x would be 3.6

Step-by-step explanation:

If you see the relation or ration between the ABCD triangle and the EFGH then we can see that the side 2 is multiplied by 1.5 to get to 3. so you do the same thing to 2.4 and multiple that by 1.5 and 3.6.

0 Example: Loan payments of $400 due 95 days ago and $700 due today
are to be repaid by a payment of $600 thirty days from today and the
balance in 125 days. If money is worth 6% and the agreed focal date is
125 days from today, what is the size of the final payment?​

Answers

Answer:

[tex]X=\$519.48[/tex]

Step-by-step explanation:

From the question we are told that

Loan 1 [tex]X_1=\$400[/tex]

Loan 1 due [tex]t_1=95days[/tex]

Loan 2 [tex]X_2=\$700[/tex]

Loan 2 due[tex]t_2=0days[/tex]

Payment [tex]Y=\$600[/tex]

Worth of money [tex]w=6\%[/tex]

Payment due [tex]t=30days[/tex]

Focal date [tex]t_f=125days[/tex]

Generally [tex]\$400[/tex] was due 95days ago

Therefore

[tex]125+90=220days[/tex](total days to consider)

Therefore

[tex]300+400 =700[/tex] is due today

125days left

Given

600 due in 30days

[tex]125-30=95days[/tex]

Generally the Final payment is mathematically given by

[tex]400(1+ 0.06*\frac{220}{365} ) + 700(1+0.06*\frac{125}{365} )=600(1+0.06*\frac{95}{365} )+X[/tex]

[tex]X=1128.9692 - 609.3698[/tex]

Therefore the

[tex]X=\$519.48[/tex]

What is a reasonable estimate for 2,590 divided by 15? Please explain.

Answers

Answer:

172.7

Step-by-step explanation:

2590 divided by 15 = 172.6666667

7 is greater than five so the 6 gets rounded up which makes the answer 172.7!

2590 divided by 15 can be calculated by division operation and it will be equal to 172

What is division?

Division is a mathematical operation, in which we distribute the number in equal parts, the number on the upper side is the total quantity and the number on the bottom side is equal parts of numbers which have to be distributed.

We denote division by '÷' this symbol.

To divide 2,590 by 15, we can think of it as breaking up 2,590 into 15 equal parts. Each of these parts will have a value of 172, since 2,590 divided by 15 is equal to 172.

In mathematical terms, division is the inverse operation of multiplication. When we divide 2,590 by 15, we are asking, "How many times does 10 fit into 2,590?" The answer is 50, so 2,590 divided by 15 is equal to 172.

So, in summary, 2,590 divided by 15 is equal to 172, and this means that 2,590 can be evenly divided into 15 parts, each of which has a value of 172.

Show that x < 5.​

Answers

Answer:

Look below

Step-by-step explanation:

-x*3x*2x=6x^3

-6x^3<900

-(cube root both sides)

-6x<9.654893846

-divide by 6

-x=1.609148974

And since 1.609148974 is less than 5, that means that X<5 is correct and hence proved

For given cuboid, x < 5

What is cuboid?

"It is a three-dimensional geometric structure that has six rectangular faces, twelve edges and eight vertices."

Formula of the volume of the cuboid:

V = l × w × h

where, l: length of the cuboid

w: width of the cuboid

h: height of the cuboid

For given example,

We have been given the total volume of the cuboid is less than 900 cm^3

⇒ V < 900 cm³

the length of the cuboid (l) = 3x

the width of the cuboid (w) = 2x

the height of the cuboid (h) = x

Using the formula of the volume of the cuboid,

⇒ V < 900

⇒ l × w × h < 900

⇒ (3x) × (2x) × (x) < 900

⇒ 6x³ < 900

⇒ x³ < 150

⇒ x < 5.3

x < 5

Therefore, for given cuboid, x < 5

Lin is solving the inequality 15−x<14. She knows the solution to the equation 15−x=14 is x=1 How can Lin determine whether x>1 or x<1 Is the solution to the inequality?

Answers

Answer:

x > 1

Step-by-step explanation:

Given the inequality ; 15 - x < 14

Since the solution to the equation 15−x=14 is x=1 ;

Then we obtain the value of x for which the inequality expression is true :

If x > 1 ; take x = 2

15 - 2 < 14

13 < 14 (true)

If x < 1 ; take x = 0

15 - 0 < 14

15< 14 (not true)

Hence, solution is x > 1

Answer:

Step-by-step explanation:

<Q is common to both triangles.

130 / 40 = 3.25

Call DQ = x

40/130 = x / (x + 72)       Cross multiply

40*(x + 72) = 130*x

40x + 2880 = 130x      Subtract 40 x from both sides

2880 = 90 x                 Divide by 90

x = 32

(72 + 32)/32 = 104/32 = 3,25

The ratios are the same.
