Which of the following statements are true?
I. All rectangles are squares.
II. All squares are rectangles.
III. Some quadrilaterals are rectangles.
Answer: the III
Step-by-step explanation: because rectangles are a type of quadrilaterals
Answer:
The answer is Some quadrilaterals are rectangles.
Step-by-step explanation:
A rectangle is a parallelogram with four right angles, so all rectangles are also parallelograms and quadrilaterals. On the other hand, not all quadrilaterals and parallelograms are rectangles. A rectangle has all the properties of a parallelogram, plus the following: The diagonals are congruent.
At most, Bob can spend $50 on sandwiches and chips for his picnic. He already bought chips for six dollars and will buy sandwiches that cost $4.50 each. How many sandwiches can buy?
50 - 6 = 44
44 / 4.50 = 9.77777778 ( 9 sandwich cuz u can get 0.77777778 of a sandwich.)
He can buy 9
A ladder that is 13 feet long leans against a building .The bottom of the ladder is 5 feeet away from the base of the building .how far up the side of the building does the ladder reach?
Length of the ladder = 13 m
Foot of the ladder from the wall = 5 m.
The upper end of the ladder is (13^2–5^2)^0.5 = 12 m above the ground.
In 1 second the foot of the ladder is 7 m from the wall, while the top end is (13^2–7^2)^0.5 = (169–49)^0.5 = 120^0.5 = 10.95 m. Then the top moves 1.05 m downwards.
In 2 seconds, the foot of the ladder is 9 m from the wall, while the top end is (13^2–9^2)^0.5 = (169–81)^0.5 = 88^0.5 = 9.38 m. Then the top moves 3.62 m downwards.
In 3 seconds, the foot of the ladder is 11 m from the wall, while the top end is (13^2–11^2)^0.5 = (169–121)^0.5 = 48^0.5 or 6.93 m. Then the top moves 6.07 m downwards.
So, if the foot of the ladder moves at a constant rate of 2 m/s the top end of the ladder moves downwards which varies from second to second.Answer: The lader will form the hypotenuse. Length of hypotenuse = 13m.
Let us take the horizontal distance between the wall and the ladder as ‘ground’. This g = 5m
wall ^ 2 + ground ^ 2 = 13^2 = 169
w^2 + g^2 = 169
w^2 + 25 = 169. Thus, w^2 = 144. Thus, w = 12
Rate of change of ground distance = dg / dt = 2m/s (given).
In the equation w^2 + g^2 = 169, differentiate the equation with respect to time.
2 w dw/dt + 2 g dg/dt = 0
2 (12) (dw/dt) + 2 (5) (2) = 0. So, 24 dw/dt + 20 = 0
dw/dt = -20 / 24 = -5 / 6
Thus, the height of the wall is decreasing at a rate of -5/6 m / s (that is, -0.833m/s)
The minus sign denotes that the height of the ladder is falling.

The bike store marks up the wholesale cost of all of the bikes they sell by 30%. Andre wants to buy a bike that has a price tag of $125. What was the cost of this bike before the markup?
Answer:
$96.15
Step-by-step explanation:
Given data
markup = 30%
cost price= $125
let the cost price before markup be x
125-30/100*x= x
125-0.3x= x
125= x+0.3x
125= 1.3x
divide both sides by 1.3
x= 125/1.3
x= $96.15
Hence the price before markup is $96.15

Answer:
a) 21 √m inches
b) 13√2/2 m
Step-by-step explanation:
a) we want to find the perimeter of an equilateral triangle
An equilateral triangle is one which sides has the same equal length
The perimeter of this triangle is the sum of the lengths of the three sides
Mathematically, we have this as:
7 √m + 7 √m + 7 √m
= 21 √m inches
b) we want to calculate the perimeter of the given rectangle
Mathematically, we can calculate the perimeter of a rectangle using the formula below;
P = 2(l + b)
where l represents the length of the rectangle and b represents the breadth of the rectangle
From the given shape;
l = √50 m, b = 1/2 √32
So, we have the perimeter follows;
2( √32/2 + √50)
= √32 + √50/2
√32 = 4√2
√50 = 5√2
Thus, we have;
4 √2 + 5 √2/2
= (8 √2 + 5 √2)/2 = 13√2/2

Find an
expression which represents the difference when (-4x – 3y) is subtracted
from (–2x – 10y) in simplest terms.
The expression that represents the difference of the polynomials is: 2x - 7y.
How to Subtract Polynomials?Given the two polynomials, (-4x – 3y) and (–2x – 10y), to subtract them, open the bracket and combine like terms.
(–2x – 10y) - (-4x – 3y)
–2x – 10y + 4x + 3y
Combine like terms
-2x + 4x - 10y + 3y
2x - 7y
Thus, the expression is: 2x - 7y

zack spent 1/2 as much time on his homework a shaunda plus an additional 3 hours write an expression to represent the number of hours zack spent on his homework
Answer:
[tex]y=\frac{1}{2}x+3[/tex]
Step-by-step explanation:
Let y equal the total amount of time spent on homework. Regardless of Shaunda's time spent on homework, represented by x, Zack spends half the time, represented by the 1/2. The additional 3hrs represents the y intercept, making it added on to the 1/2x expression.
