Answer:

(7.5,4.1)

Step-by-step explanation:

Given

3x_7y =_40

3x_2y=_4

sol

3x_7y=_40..... equation 1

3x_2y=_4 ..... eq 2

here

eq 2 multi 3 eq 1 multiply 3

9x_21y=_120

9x_6y=_12

_ + = +

__________

0x+ 15y =108

y=108÷15

y=7.5

the y value putting the eq 1

3x_7y=_40

3x_7×7.5=_40

3x_52.5=_40

3x=52.5_40

3x=12.5

x=12.5÷3

x=4.1

Step-by-step explanation:

its easy use a calculator and in place of x put 1.5 and in place of y put 3.

Answer:

Width of rectangle = 83 meter

Step-by-step explanation:

Given:

Area of rectangle = 8,051 m²

Length of rectangle = 97 m

Find:

Width of rectangle

Computation:

Area of rectangle = Length of rectangle x Width of rectangle

97 x Width of rectangle = 8,051

Width of rectangle = 8,051 / 97

Width of rectangle = 83 meter

Step-by-step explanation:

Answer:

The answer is pentagon

Given:

The sequence is 8, 10, 12.5, 15.625,...

To find:

The explicit formula for the given sequence.

Solution:

We have,

8, 10, 12.5, 15.625,...

Here, the first terms is 8.

[tex]\dfrac{10}{8}=1.25[/tex]

[tex]\dfrac{12.5}{10}=1.25[/tex]

[tex]\dfrac{15.625}{12.5}=1.25[/tex]

The common ratio is 1.25. So, the given sequence is a geometric sequence.

The explicit formula for a geometric sequence is:

[tex]a_n=ar^{n-1}[/tex]

Where, a is the first term and r is the common ratio.

The explicit formula for the given geometric sequence is:

[tex]a_n=8(1.25)^{n-1}[/tex]

Therefore, the correct option is A.

Answer:

The slope is 2

Step-by-step explanation:

Step-by-step explanation:

Oliver deposits P= $1,000

Then total amount A after n months given that the balance increases by %15 each month can be calculated as

[tex]A= 1000(1+15/100)^n[/tex]

Assuming the increase in amount is compounded monthly.

Answer:

X - .4x

Step-by-step explanation:

X - .4x = x(1-.4) = .6x

1 -0.4x  These are not like terms so they cannot be combined

X + 0.6 These are not like terms so they cannot be combined

0.6X - X  x( .6-1) = x(-.4) = -.4x

Answer:

45°

Step-by-step explanation:

AD⊥BC, BE⊥AC, CF⊥AB           AB = CK

∠1 + ∠2 = 90°        ∠5 + ∠2 = 90°              ∴ ∠1 = ∠5

∠5 + ∠4 = 90°                                            ∴ ∠4 = ∠2

AB = CK

ΔABD ≅ ΔCKD  (ASA)

AD = CD       ∴ΔADC is an isosceles triangle

∠C = ∠CAD = 45°       (∠C + ∠CAD = 90°)

Answer:

perimeter of a rectangle

=2×(L+B)

=2×(4.3+3.4)

=2×7.7

=15.4

Area of a rectangle

=L×B

=4.3×3.4

=146.2

Answer:

Step-by-step explanation:

The formula for the perimeter of a rectangle of length L and width W is

P = 2L + 2W.  In this particular problem, P = 2(3.4 cm) + 2(4.3 cm), or

P = 6.8 cm + 8.6 cm, or P = 15.4 cm

The formula for the area of a rectangle of length L and width W is A = L * W.

In this problem, the area is A = (3.4 cm)(4.3 cm) = 14.62 cm^2  =  A

Answer:

16,800 Euros.is the answer

Step-by-step explanation:

Answer:

The question gives the fact that both lines are parallel.

So:

3p - 15 =  7p - 5

3p = 7p + 10

-4p = 10

p = 10/-4

p = 5/-2

Answer:

The answer is 3p - 15 =  7p - 5    3p = 7p + 10    -4p = 10  p = 10/-4  p = 5/-2

Answer:

I believe it's C. (3 x 2) + 7!

The expression that could be used to find the number of cubes that would fill the prism will be (3 x 2) x 7. The correct option is D.

A rectangular prism is a polyhedron in geometry that has two parallel and congruent bases. It also goes by the name cuboid. Six faces, each with a rectangle shape and twelve edges, make up a rectangular prism. It is referred to as a prism because of the length of its cross-section.

The rectangular prism has a base of cubes that is 3 units long and 2 units wide, which means it has an area of 3 x 2 = 6 square units.

The prism is also 7 cubes tall. To find the total number of cubes in the rectangular prism, we need to multiply the area of the base by the height of the prism. Therefore, the expression that could be used to find the number of cubes that would fill the prism is:

(3 x 2) x 7 = 6 x 7 = 42

So the answer is D. (3 x 2) x 7.

Step-by-step explanation:

Let the required integers be x,x+1,x+2.

Therefore,

x+x+1+x+2=45

3x+3=45

3x=42

x=14

Hence, the required integers are 14,15,16.

Answer:8 or 9 ft

Step-by-step explanation:

Given

The area of the pool is  [tex]A=x^2-17x+72[/tex]

The area is in the form of a quadratic equation

So, the roots of the equation will give the length and width of the pool

[tex]\Rightarrow x^2-17x+72=0\\\Rightarrow x^2-8x-9x+72=0\\\Rightarrow x(x-8)-9(x-8)=\\\Rightarrow (x-8)(x-9)=0\\\Rightarrow x=8\ or\ 9[/tex]

Therefore length and width can either be [tex]\text{8 or 9 ft}[/tex].

[tex]\Rightarrow L=8\ ft,W=9\ ft\ \text{or}\ L=9\ ft,W=8\ ft[/tex]

Answer: [tex]49.7^{\circ}F[/tex]

Step-by-step explanation:

Given

The temperature on the ground is [tex]56.9^{\circ}F[/tex]

temperature drop observed is [tex]1.2^{\circ}F\ \text{per 1000 ft}[/tex]

The height of the plane is  [tex]6000\ ft[/tex]

The total increase in height per [tex]1000\ ft[/tex] is [tex]6[/tex] units

Temperature drop is

[tex]\Rightarrow 1.2\times 6=7.2^{\circ}F[/tex]

The temperature at that altitude is

[tex]\Rightarrow 56.9-7.2=49.7^{\circ}F[/tex]
