What do you notice about their slopes?
Answers
slope CD = -3
Im not sure about the last part but I think the product of slope AB and slope CD is -1 so line AB is perpendicular to line CD.

So that leaves A eliminated.
It shouldn't be B because, you have to count the numbers to the left of the decimal.
So that leaves B eliminated.

What is the measurement of angle x (in degrees)?
Explain how you got your answer.
Answers
the little box you see means that the angle is 90 degrees in total
so that means this angle is a complementary angle (if you add two angles, the sum is 90 degrees)
so to solve for x your equation would be: 90-55 = x
90 - 55 = x
35 = x

Luke was out of cereal for breakfast. He walked to the grocery store to buy his favorite, Honey Nut Cheerios. While looking at the cereal, he noticed all the different box sizes and different prices. A giant "Family Size" box contained 14.7 oz and cost $5.99. A small, individual size contained 1.5 oz and cost $1.89. He wanted to get the most "bang for his buck." Which choice is the better buy? In other words, which choice is cheaper per ounce? Which one should he buy and why?
Answers
Answer:
The answer is the family size
Step-by-step explanation:
I had to find how much it is per ounce and for the small box it cost $1.25 per ounce and for the family size it cost $0.41 which is less than $1.25 so the answer would be the family size of Honey Nut Cheerios

Mathematics includes the study of such topics as quantity, structure, space, and change. It has no generally accepted definition. Mathematicians seek and use patterns to formulate new conjectures; they resolve the truth or falsity of such by mathematical proof.

Mathematics is the study of numbers, shapes and patterns. The word comes from the Greek word "μάθημα" (máthema), meaning "science, knowledge, or learning", and is sometimes shortened to maths (in England, Australia, Ireland, and New Zealand) or math (in the United States and Canada). ...

On the map below, city p and city q are 5.5 centimeters (cm) apart. What is the actual distance between city p and city q? 2cm= 35 miles
Answers
Answer:
96.25
Step-by-step explanation:
5.5/2=2.75
2.75x35=96.25
Meaning ONE centimeter is 35/2, or, 17.5 miles of actual distance
And half, or 0.5 of a centimeter is 17.5/2 or 35/4, which is 8.75 miles
5 centimeters is 2 + 2 + 1 + 0.5
(35 miles) plus (35 miles) plus (17.5 miles) plus (8.75 miles) which would add up to be 96.25 miles

You want to measure the length of a ribbon in inches. You only have a centimeter ruler. The length of the ribbon is 15 cm. Is the ribbon longer or shorter than 15 inches? How many inches long is it?
Answers
Answer:
Shorter than 15IN, 5.9 or 6 inches
Hope this helps:)
Step-by-step explanation:
The ribbon is shorter than 15 inches, and its length is approximately 5.91 inches.
Given that a ribbon has a length of 15 cm, we need to calculate the length in inches,
To determine the length of the ribbon in inches, we need to convert the length from centimeters to inches.
To convert centimeters to inches, we can use the conversion factor 1 inch = 2.54 centimeters.
The length of the ribbon is 15 centimeters. To convert this to inches, we divide 15 by 2.54:
15 cm / 2.54 cm/inch = 5.91 inches (rounded to two decimal places).
So, the ribbon is shorter than 15 inches.
The ribbon is approximately 5.91 inches long.

Mrs. Taylor is knitting socks. it takes her 1/4 hour to knit one pair of socks. She has a meeting to go to in 3 1/2 hours.
How many pairs of socks can she knit before her meeting?
Answers
Answer:
14 socks.
Step-by-step explanation:
3 1/2 / 1/4
= 7/2 / 1/4
= 7/2 * 4
= 28/2
= 14 socks.
Answer:
14
Step-by-step explanation:
Mrs. taylor can knit 4 socks in an hour, so if she has to go to her meeting in 3 1/2 hours, she should be able to knit 14 pairs of socks. The reason for this is in 3 hours she can knit 12 socks because 4 times 3 is 12. Then, in half an hour she can knit 2 socks because she can knit one pair in 1/4 so in 1/2 it would be 2.
What is the density at 20oC of 12.0 milliliters of a liquid that has a mass of 4.05 grams?
(if you don't know don't answer it please)
Answers
Answer:
Density is defined as mass per unit volume:
density = mass/volume
Density can be calculated using the mathematical formula (expression):
d = m ÷ V
where d = density, m = mass, V = volume
The greater the density, the more mass per unit volume.
The unit of density derived from SI units is kilograms per cubic meter, kg/m3 or kg m-3.
More commonly, densities are given in g/mL (g mL-1) or g/cm3 (g cm-3 or g/cc).
Density is a characteristic property of pure substances so density can help identify a particular pure substance.
Since different substances have different densities, density can also be used to separate one substance from another.
In general, solids are more dense than liquids which are more dense than gases:
density of solid > density of liquid > density of gas
Step-by-step
Answer:
0.338 g/mL
Step-by-step explanation:
Density is the mass per unit volume of any object. It is calculated by dividing the mass of an object by its volume. This is:
ρ = m/V
ρ = 4.05 g / 12 mL
ρ = 0.3375 g/mL
ρ ≅ 0.338 g/mL
