Answer:
Step-by-step explanation:
The ratio is the relationship of two numbers. ... A rate is a little bit different than the ratio, it is a special ratio. It is a comparison of measurements that have different units, like cents and grams. A unit rate is a rate with a denominator of 1.
The difference between ratio and unit rate is that both of them are measures of two units and are written in the form of a numerator and a denominator but the unit rate denominator must be one.
What is a ratio?It shows how many times one value is contained in another value.
The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
Ratio and unit rate
Ratio and unit rate both are written in the form of a numerator and a denominator.
The ratio is a measure of two units contained in a whole amount.
Example: 3 apples and 3 mangoes are contained in a bag
The ratio of apple and mango is 3:3 = 1:1
The unit rate is also a measure between two units but the denominator should always be one.
Example: A man can run 10 miles in 10 hours
In one hour 1 mile.
The unit ratio is 10miles per hour.
Thus,
The difference between ratio and unit rate is that both of them are measures of two units and are written in the form of a numerator and a denominator but the unit rate denominator must be one.

9514 1404 393
Answer:
$8,775
Step-by-step explanation:
The amount due is given by the formula ...
A = P(1 +rt)
where P is the principal amount, r is the annual rate, and t is the number of years.
A = $6,500(1 +0.07×5) = $6,500(1.35) = $8,775

6. Stacy has 3 lb of grapes to make 10 bowls of fruit salad. If her recipe calls
for 4 oz of grapes per bowl, will she have enough grapes? How much leftover
does she have, or how much extra is needed?
Answer:
4.8oz
Step-by-step explanation:
So 1lb=16oz
16x3=48oz
48/10=4.8
Distributing them out she has little over enough for all 10
She will have half pound or 8 oz of grapes leftover.
What is unit conversion?The same attribute is expressed using a unit conversion, but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometers, feet, or any other measurement unit instead of miles.
Given, Stacy has 3 lb. of grapes to make 10 bowls of fruit salad.
Since, 1 lb. = 16 oz.
So, Stacy has total grapes = 48 oz.
1 bowl of fruit salad Required = 4 oz. of grapes
Thus,
10 bowl of fruit salad required = 40 oz. of grapes
So, Leftover grapes = 48 -40
Leftover grapes = 8 oz or 1/2 lb.
Therefore, She will have half pound of grapes leftover.

A bag contains red marbles, white marbles, and blue marbles. Randomly choose two marbles, one at a time, and without replacement. Find the following. Enter your answers as fractions or decimals rounded to three decimal places.
(a)The probability that the first marble is red and the second is blue.
P(first white and second blue) =
The probability that both are the same color.
P(same color) =
Answer:
[tex]P(First\ White\ and\ Second\ Blue) = \frac{3}{28}[/tex]
[tex]P(Same) = \frac{67}{210}[/tex]
Step-by-step explanation:
Given (Omitted from the question)
[tex]Red = 7[/tex]
[tex]White = 9[/tex]
[tex]Blue = 5[/tex]
Solving (a): [tex]P(First\ White\ and\ Second\ Blue)[/tex]
This is calculated using:
[tex]P(First\ White\ and\ Second\ Blue) = P(White) * P(Blue)[/tex]
[tex]P(First\ White\ and\ Second\ Blue) = \frac{n(White)}{Total} * \frac{n(Blue)}{Total - 1}[/tex]
We used Total - 1 because it is a probability without replacement
So, we have:
[tex]P(First\ White\ and\ Second\ Blue) = \frac{9}{21} * \frac{5}{21 - 1}[/tex]
[tex]P(First\ White\ and\ Second\ Blue) = \frac{9}{21} * \frac{5}{20}[/tex]
[tex]P(First\ White\ and\ Second\ Blue) = \frac{9*5}{21*20}[/tex]
[tex]P(First\ White\ and\ Second\ Blue) = \frac{45}{420}[/tex]
[tex]P(First\ White\ and\ Second\ Blue) = \frac{3}{28}[/tex]
Solving (b) [tex]P(Same)[/tex]
This is calculated as:
[tex]P(Same) = P(First\ Blue\ and Second\ Blue)\[/tex][tex]or\ P(First\ Red\ and Second\ Red)\ or\ P(First\ White\ and Second\ White)[/tex]
[tex]P(Same) = (\frac{n(Blue)}{Total} * \frac{n(Blue)-1}{Total-1})+(\frac{n(Red)}{Total} * \frac{n(Red)-1}{Total-1})+(\frac{n(White)}{Total} * \frac{n(White)-1}{Total-1})[/tex]
[tex]P(Same) = (\frac{5}{21} * \frac{4}{20})+(\frac{7}{21} * \frac{6}{20})+(\frac{9}{21} * \frac{8}{20})[/tex]
[tex]P(Same) = \frac{20}{420}+\frac{42}{420} +\frac{72}{420}[/tex]
[tex]P(Same) = \frac{20+42+72}{420}[/tex]
[tex]P(Same) = \frac{134}{420}[/tex]
[tex]P(Same) = \frac{67}{210}[/tex]

B) 153.86 square cm (Area)
4.
A) 62.8 ft (Circumference)
B) 314 square ft (Area)
Step-by-step explanation:
3. Radius 7 cm
7*2=14 (Find the diameter)
14*3.14= 43.96 cm (Circumference)
7*7=49 (Find the square of radius)
49*3.14 = 153.86 square cm (Area)
4. Diameter: 20 ft
20*3.14 = 62.8 ft (Circumference)
20/2=10
10*10=100
100*3.14= 314 square ft (Area)

I need help on this badly please come with good explanation on how to slove problems like this.
Answer:
Step-by-step explanation:
This is a parabola. Because of that, the extreme exists at either the highest point on the graph or at the lowest point on the graph (which is also known as the vertex). This is a positive parabola, so the vertex is a minimum. The coordinates of the vertex are (4, -2.5). The 4 is the x value; therefore, the value of x where the polynomial has an extreme (or extrema) is at x = 4
Jessica is making 2 loaves of bread she needs 3/4 cup of sugar for each loaf her measuring cup only holds 1/4 cup how many times will the cup need to be filled
Answer:
The cup will be filled 6 times.
Step-by-step explanation:
If her measuring cup only holds 1/4 cups then we need to find how many 1/4 cups are in 3/4 cups:
(1/4) + (1/4) + (1/4) = 3/4
3/4 = 3/4
The measuring cup will have to be filled 3 times for 1 loaf.
If she has 2 loaves that means that she has to fill her 1/4 measuring cup 6 times (because 2 * 3 = 6)

are squares parallelograms
9514 1404 393
Answer:
yes
Step-by-step explanation:
A parallelogram is a quadrilateral with opposite sides parallel. A square is such a quadrilateral, so a square is a parallelogram.
_____
A rhombus is a special case of parallelogram in which adjacent sides are the same length.
A square is a special case of rhombus in which the angles are 90°. Hence a square is a special case of parallelogram.
__
An alternate route to the same conclusion is ...
A rectangle is a special case of parallelogram in which vertex angles are 90°.
A square is a special case of rectangle in which adjacent sides are the same length. Hence a square is a special case of parallelogram.
