A recipe for pie dough calls for a ratio of butter to flour of 4/5 : 3 1/3 . If you plan to use 6 2/3 cups of flour, how much butter should you use to keep the same ratio?
Answer:
1 3/5
Step-by-step explanation:
to determine the answer, take the following steps :
determine how much larger the amount of flour you intend to use is more than that indicated in the recipeMultiply the answer gotten in the above step by the amount of flower indicated in the recipe6 2/3 ÷ 3 1/3
20/3 x 3/10 = 2
2 x 4/5 = 8/5 = 1 3/5
Use a net to find the surface Area of the square pyramid The height of the pyramid is 9 yes and the base sides are all 2.5 yrds and its a square as a base
Answer:
[tex]Area = 51.68yd^2[/tex]
Step-by-step explanation:
Given
[tex]h = 9yd[/tex] -- height
[tex]a = 2.5yd[/tex] --- base sides
Required
Determine the surface area
The net is not given. So, I will solve directly.
The surface area is calculated as:
[tex]Area = a^2 + 2a\sqrt{\frac{a^2}{4} + h^2}[/tex]
So, we have:
[tex]Area = 2.5^2 + 2*2.5\sqrt{\frac{2.5^2}{4} + 9^2}[/tex]
[tex]Area = 6.25 + 5\sqrt{\frac{6.25}{4} + 81}[/tex]
[tex]Area = 6.25 + 5\sqrt{1.5625 + 81}[/tex]
[tex]Area = 6.25 + 5\sqrt{82.5625}[/tex]
[tex]Area = 6.25 + 5* 9.086[/tex]
[tex]Area = 51.68yd^2[/tex]

What is the perimeter of the rectangle whose vertices are at (6, 3), (−6, 3), (−6, −1), and (6, −1)?
Given:
The vertices of a rectangle are (6, 3), (−6, 3), (−6, −1), and (6, −1).
To find:
The perimeter of the rectangle.
Solution:
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2-(y_2-y_1)^2}[/tex]
Let the vertices of a rectangle are A(6, 3), B(−6, 3), C(−6, −1), and D(6, −1).
Using the distance formula, we get
[tex]AB=\sqrt{(-6-6)^2-(3-3)^2}[/tex]
[tex]AB=\sqrt{(-12)^2-(0)^2}[/tex]
[tex]AB=\sqrt{144}[/tex]
[tex]AB=12[/tex]
Similarly,
[tex]BC=\sqrt{\left(-6-\left(-6\right)\right)^2+\left(-1-3\right)^2}=4[/tex]
[tex]CD=\sqrt{\left(6-\left(-6\right)\right)^2+\left(-1-\left(-1\right)\right)^2}=12[/tex]
[tex]AD\sqrt{\left(6-6\right)^2+\left(-1-3\right)^2}=4[/tex]
Now, the perimeter of the rectangle is:
[tex]Perimeter=AB+BC+CD+AD[/tex]
[tex]Perimeter=12+4+12+4[/tex]
[tex]Perimeter=32[/tex]
Therefore, the perimeter of the rectangle is 32 units.

Answer:
[tex]\frac{6}{8}[/tex] or [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
Convert the mixed numbers into improper fractions.
[tex]2\frac{3}{8}-1\frac{5}{8}=\frac{19}{8}-\frac{13}{8}[/tex]
Since the two fractions have the same denominator, just subtract the numerators.
[tex]\frac{19}{8}-\frac{13}{8}=\frac{6}{8}[/tex]
If required, rewrite the fraction in simplest form.
[tex]\frac{6}{8}=\frac{3}{4}[/tex]

Matthew is cutting construction paper into rectangles for a project. He needs to cut one rectangle that is 12 inches x 14 1/4 inches. He needs to cut another rectangle that is 10 1/2 inches by 10 1/4. How many total square inches of construction paper does Matthew need for his project?
PLEASE HELP ME FOR REAL!!!
Answer:
I got 278 5/8
Step-by-step explanation:
the question stated square inches which I referred
to as area. You multiply both rectangles than add them together. I may be wrong but I hope this gives you a lead! :)
The total square inches of construction paper does Matthew need for his project is,
⇒ 278.63 inches²
What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
Given that;
Matthew is cutting construction paper into rectangles for a project.
And, He needs to cut one rectangle that is 12 inches x 14 1/4 inches.
He needs to cut another rectangle that is 10 1/2 inches by 10 1/4.
Hence, We get;
Area of first rectangle = 12 x 14 1/4
= 12 x 57 / 4
= 171 inhces²
And, Area of second rectangle = 10 1/2 x 10 1/4
= 21/2 x 41/4
= 107.63 inches²
Hence, The total square inches of construction paper does Matthew need for his project is,
⇒ 171 + 107.63 inches²
⇒ 278.63 inches²

A fine fabric was selling for $10.50 per half yard. Joni bought 2 1/3 yards. How much did he spend? Brainliest for correct answer. (ANSWER ISN'T 45.5)
Answer:
45.5
Step-by-step explanation:
First you would find 1/3 third of 10.50 and it is 3.5, you would then do 10.50 x 4 since it said 10.50 per half a yard, so you would do times 4 and you would get 42, you would then add 42 + 3.5 which equals 45.5.

You invite your best friend Sheila out for a picnic on Thursday. Sheila tells you "If it rains, there is a 20% probability
that I will come, but if it's sunny, there is an 80% probability that I will come." You check the weather and see that
there is a 40% chance of rain for that day. What is the overall probability that Sheila will attend your picnic? Explain
how you found your answer.
Answer: 56%
Probably that it will rain and she goes + probably that it will be sunny and she goes
= 0.4 * 0.2 + 0.6*0.8
= 0.08 + 0.48
= 0.56
56% chance
If MO bisects angle PMN, the measure of angle PMN equal 74 and the measure of angle OMN equals 2x + 7, find the value of x

Nkechi wants to use a one-sample z interval to estimate what proportion of candies in a bag are red. She takes a random sample of 24 of the 80 total candies and finds that 18 of the candies in the sample are red. Which conditions for constructing this confidence interval did Nkechi's sample meet? Choose all answers that apply
Answer: The data is a random sample from the population of interest.
Step-by-step explanation: The condition is met since she randomly selected the sample from the population of interest.
The data is a random sample from the population of interests.(Option A), and individual observations can be considered independent.(Option C)
What are the conditions for valid inference about one proportion?Random sample: The sample should be taken randomly.Normal distribution of proportion: The sampling distribution of the proportion we're taking about should be normally distributed.Independent observations: Each of the observations must be independent.The missing options are:
A. The data is a random sample from the population of interests.
B The observed counts of successes and failures are both sufficiently large.
C. Individual observations can be considered independent.
For this case, we're given that the sample was random.
Sample size is 24,which is not sufficiently large (usually we take > 30 as sufficiently large size).
Also, each candle was independent for being red colored.
Thus, the data is a random sample from the population of interests.(Option A), and individual observations can be considered independent.(Option C)

Answer:
0 is not in domain
5 is not in domain
10 is in domain
Step-by-step explanation:
10 is in domain because inputting 10 into the function gives an output of 0
0 is not in th domain because 0 gives us the square root of a negative number, and the quare of a negative number isnt a real number
5 is not in the domain for the same reason
