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

Find the perimeter and area of a rectangle with a length of 3.4cm and a width of 4.3cm
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

8. Which expression is equivalent to 0.6x?
O
X-0.4x
O
1 -0.4x
X + 0.6
0.6X - X
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

The heights of a triangle ABC meet at a point K.AB=CK.Find the angle of C.
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°)
The sum of 3 consecutive integers is 45. What is the product of the 1st and 3rd number.
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.
Suppose there is a 1.2°F drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 56.9°F, what will be the temperature when the plane reaches an altitude of 6,000 ft?
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(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
Tyler stands facing a tree that is 9 meters tall. he places a straight stick on the ground at his feet, angles it up until it points to the top of the tree, and measures the angle as 55 degrees. how many meters away is he standing from the tree?
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.)

Angie packed same-size cubes into a rectangular prism. Image shows a base of cubes 3 units long, 2 units wide, and with a column of cubes 1 cube wide and 7 cubes tall. Which expression could be used to find the number of cubes that would fill the prism? A. ( 3 + 2 ) + 7 B. ( 3 × 2 ) × 6 C. ( 3 × 2 ) + 7 D. ( 3 × 2 ) × 7
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.
What is a rectangular prism?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.

The area of a rectangular parking lot is 8051 m ^2 . If the length of the parking lot is 97 m, what is its width?
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

Mrs. Harbrook can choose from two rectangular pool sizes. The pool manufacturer provides her with the area of the pool, but she needs to find the dimensions in order to determine if the pool will fit in her yard.
If the area of the pool is x2−17x+72, what are possible expressions to represent the length L and the width W ?
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]
