Answer:
[tex]\dfrac{15}{2}[/tex]
Step-by-step explanation:
The average speed of the Erin is 120/16 mph
Here,
Numerator = 120
Denominator = 16
mph = miles per hour
We need to find an expression expressed as a decimal.
So,
[tex]\dfrac{120}{16}=\dfrac{2\times 3\times 2\times 2\times 5}{2\times 2\times 2\times 2}\\\\=\dfrac{15}{2}[/tex]
So, the final answer is [tex]\dfrac{15}{2}[/tex].

Work out the area of a circle whose diameter is equal to 14 cm.
Give your answer correct to 2 decimal places.
cm?
help
Given:
The diameter of the circle = 14 cm
To find:
The area of the circle.
Solution:
We have,
Diameter of the circle = 14 cm
We know that the radius of the circle is half of its diameter. So,
[tex]r=\dfrac{14}{2}[/tex]
[tex]r=7\text{ cm}[/tex]
The area of a circle is:
[tex]A=\pi r^2[/tex]
Substituting [tex]\pi=\dfrac{22}{7}, r=7[/tex] in the above formula, we get
[tex]A=\dfrac{22}{7}\times (7)^2[/tex]
[tex]A=22\times 7[/tex]
[tex]A=154[/tex]
Therefore, the area of the circle is 154 square cm.
Find the volume of each figure. Round to the nearest tenth. Plz show work
use 3.14 for π round to the nearest tenth
Answer:
A=4pi(r)^2
A=4pi(5)2
A=4pi25
A=314.16 rounds to 314.6 m
Volume=4/3pi(r)^3
volume=4/3pi(5)^3
volume=4/3pi(125)
volume=523.59 rounds to 523.6 m
hope this helps
have a good day :)

The vertices of a triangle are \large A\left(-4,-2\right), \large B\left(1,3\right) and \large C\left(4,-2\right).
Answer:
[tex]Area = 20[/tex]
Step-by-step explanation:
Given
[tex]\large A\left(-4,-2\right), \large B\left(1,3\right), \large C\left(4,-2\right).[/tex]
Required
The area
The area of a triangle is:
[tex]Area = \frac{1}{2}|A_x(B_y - C_y) + B_x(C_y - A_y) + C_x(A_y - B_y)|[/tex]
So, we have:
[tex]Area = \frac{1}{2}|-4(3 - -2) + 1(-2 - -2) + 4(-2 - 3)|[/tex]
[tex]Area = \frac{1}{2}|-4*5 + 1*0 + 4*-5|[/tex]
[tex]Area = \frac{1}{2}|-40|[/tex]
[tex]Area = \frac{1}{2}*40[/tex]
[tex]Area = 20[/tex]

Find the length of the third side. 20 24
Answer:
Hypotenuse (Third side) = 31.24
Step-by-step explanation:
20² + 24² = Hypotenuse²
400 + 576 = Hypotenuse²
976 = Hypotenuse²
[tex]\sqrt{976}[/tex] = Hypotenuse
31.24 = Hypotenuse
Therefore, the measure of the third side would be: 31.24
Hope this helps!
every parallelogram is a square?
every rectangle with four congruent sides is a square?
every rectangle is a quadrilateral?
every quadrilateral is a rectangle?
Answer:
every parallelogram is a square? False
every rectangle with four congruent sides is a square? True
every rectangle is a quadrilateral? True
every quadrilateral is a rectangle? False
Step-by-step explanation:
every parallelogram is a square?
A parallelogram has two opposite pairs of parallel lines and opposite congruent sides. A square needs to have 4 right angles and all sides need to be equal. In the restrictions of a parallelogram, these cannot be concluded, therefore parallelogram are not always squares.
every rectangle with four congruent sides is a square?
Square require 4 congruent sides and 4 right angles. Rectangles already have 4 right angles. If you add 4 congruent sides to the mix, it means that these rectangles are always squares.
every rectangle is a quadrilateral?
A quadrilateral is defined by a shape having 4 sides. Rectangles have 4 sides, so they fit into the category of quadrilaterals.
every quadrilateral is a rectangle?
A quadrilateral is a just a shape with four sides. We do not know if it has 4 right angles, so not every quadrilateral is a rectangle.

What is the slope of the line with the equation y +2 = -3(x – 7)?
OA.m = -3
O B. m = 3
O C. m = 2
O D. m = -7
Answer:
A.m = -3
Step-by-step explanation:
This equation is written in point slope form
y-y1 = m(x-x1)
y +2 = -3(x – 7)
y - -2 = -3(x – 7)
The slope is -3 and the point is (7, -2)

Bradley wants to build a shop in his backyard. He knows the shop will be a rectangular shaped building. He wants the length of the shop to be the expression of 3x + 23 and the width to be 2x + 17. Write a trinomial that would represent the area of the shop. Show your work
Answer:
A = 6x² + 97x + 391
Step-by-step explanation:
Given that,
The length of the shop, l = (3x+23)
The width of the shop, b = (2x+17)
The expression for the area of the shop is given by :
A = lb
Put all the values,
A = (3x+23) × (2x+17)
= 6x² +51x+46x +391
= 6x² + 97x + 391
Hence, the expression for the area of the shop is equal to 6x² + 97x + 391.

What is the length of AC?
Geometry, see attachment.
Answer:
D.144
Step-by-step explanation:
[tex]\frac{7}{x} = \frac{84}{156-x}[/tex]
⇔ 84x = -7x + 1092
⇔ 91x = 1092
⇔ x = 12
⇒ AC = 156 - x = 156 - 12 = 144

of one side of the piece of land?
Answer:
I'll setup the problem, you do the calculation
Step-by-step explanation:
given the area of a square, you take the square and that is the side of the square
[tex] \sqrt{9 {q}^{4} {r}^{8} {s}^{6} } [/tex]
the square root of a number that is raised to a power is found by dividing the power by 2

Please help, my score is 89 I have to get to 90 this question is important!
Answer:
40.4
Step-by-step explanation:
Triangle TUV is similar to triangle XYZ.
Notice the order in which TUV and XYZ are written.
Angles are corresponding to angles in the same position in the names.
<T corresponds to <X.
<U corresponds to <Y.
<V corresponds to <Z.
In similar triangles, corresponding angles are congruent.
<T is congruent to <X.
<U is congruent to <Y.
<V is congruent to <Z.
m<T = m<X = 63.1°
m<U = m<Y
m<V = m<Z = 76.5°
m<X + m<Y + m<Z = 180°
63.1° + m<Y + 76.5° = 180°
m<Y + 139.6° = 180°
m<Y = 40.4°
