Can anyone find d-bar (the d with the line over it) and explain it to me? For this problem five trials are done at eight am and then twelve am. The eight am trials are 98.4, 98.6, 97.8, 97.1, and 97.5. The 12am ones are 98.9, 99, 97.9, 96.6, and 97.7. The correct answer is -0.14 but I can't get that answer.

Answer:

what?

Step-by-step explanation:

Answer:

What

Step-by-step explanation:

Whata

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:

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

sorry, I didn't know how to explain it

Answer: 11= y/6y= 66

Step-by-step explanation:

Answer:

Step-by-step explanation:

(0, -1)  (1, -3)

(-3 + 1)/(1 - 0)= -2/1= -2

y + 1 = -2(x - 0)

y + 1 = -2x + 0

y = -2x - 1

answer is C

Answer:

Distance of boy from tree (base) = 6.3 m (Approx.)

Step-by-step explanation:

Given:

Height of tree (perpendicular) = 9 m

Given angle = 55°

Find:

Distance of boy from tree (base)

Computation:

Using trigonometry function

tanθ = Perpendicular / Base

tan 55 = 9 / Base

1.4281 = 9 / Base

Base = 6.3

Distance of boy from tree (base) = 6.3 m (Approx.)

Answer:

A(t)+900=x

B(t)+500=x

for the sake of things X represents the answer and as both need to equal the same it works out so that plugging it into a calculator should give you the answer

Step-by-step explanation:

you could start by making a T chart on one Side A the other B starting with 900 at A and 500 at B go down by the appropriate increments 950, 600;1000, 700; 1050, 800; 1100, 900, 1150, 1000; 1200, 1100; 1250, 1200, and you guessed it, 1300, 1300. so there you go X=1300

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.

Answer:

Breadth is 25% of the length

Step-by-step explanation:

Length, l = 24 cm

Breadth, b = 6cm

Expressing the breadth as a percentage of the length :

(Breadth / length) * 100%

(6 / 24) * 100%

0.25 * 100%

= 25%

Hence, the breadth is 25% of the length

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

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:

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: [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]

Answer:

(a) 152.5

(b) -45.4

(c) 750

(d) -87.5

Step-by-step explanation:

To calculate the percentage increase:

First: work out the difference (increase) between the two numbers you are comparing.

Increase = New Number - Original Number.

Then: divide the increase by the original number and multiply the answer by 100.

% increase = Increase ÷ Original Number × 100.
