The number of cups of broccoli that would be needed for a pound of beef is C. 1 1/2 cup of broccoli per beef.
How to calculate the value?From the information, it was stated that Tyler was making a meal for his family and that for every 3/4 pound of beef, the recipe calls for 9/8 cups of broccoli.
Therefore, the cups of broccoli that would be needed for a pound of beef will be:
3/4/1 = 9/8/x.
where x = cups of broccoli
Cross multiply
3/4x = 9/8
x = 9/8 ÷ 3/4
x = 9/8 × 4/3
x = 3/2
x = 1 1/2cups
Therefore, the correct option is C.

Answer:
[tex]\textsf{c) \quad $1 \frac{1}{2}$ cups of broccoli per 1 lb of beef}.[/tex]
Step-by-step explanation:
Given information:
For every ³/₄ lb of beef, the recipe calls for ⁹/₈ cups of broccoli.Create a ratio of pounds of beef to cups of broccoli, where x is the number of cups of broccoli to one pound of beef:
[tex]\implies \dfrac{3}{4}: \dfrac{9}{8}=1:x[/tex]
[tex]\implies \dfrac{\frac{3}{4}}{\frac{9}{8}}=\dfrac{1}{x}[/tex]
Cross multiply:
[tex]\implies \dfrac{3}{4}x=\dfrac{9}{8}[/tex]
[tex]\implies x=\dfrac{9}{8} \div \dfrac{3}{4}[/tex]
To divide fractions, flip the second fraction (make the numerator the denominator, and the denominator the numerator) then multiply it by the first fraction:
[tex]\implies x=\dfrac{9}{8} \times \dfrac{4}{3}[/tex]
[tex]\implies x=\dfrac{9 \times 4}{8 \times 3}[/tex]
[tex]\implies x=\dfrac{36}{24}[/tex]
[tex]\implies x=\dfrac{3 \cdot \diagup\!\!\!\!\!\!12}{2 \cdot \diagup\!\!\!\!\!\!12}[/tex]
[tex]\implies x=\dfrac{3}{2}[/tex]
[tex]\implies x=1 \frac{1}{2}[/tex]
Therefore, 1¹/₂ cups of broccoli would be needed to one pound of beef.

Angle C is an acute angle with sec C = 9/4 and sin C =
√65/9. What are the values of cos C and csc C?
From trigonometric ratios we calculate the value of the cos C is 4/9 and the value of cosec C is 9/√65 .
Real functions known as trigonometric functions in mathematics connect right-angled triangle angles and the ratios of their two side lengths.
The terms trigonometric functions, circular functions, and angle functions are also used to describe them. Trigonometric functions are frequently employed in all fields of study involving geometry, including geodesy, solid mechanics, celestial mechanics, and many more. Given that one of the most fundamental periodic functions is the Fourier transform, it is frequently employed to examine periodic phenomena.Sine, cosine, and tangent are the three trigonometric functions that are employed in modern mathematics the most frequently. The less common cotangent, secant, and cosecant are their reciprocals. The hyperbolic functions and their corresponding inverse functions have analogues for each of these six trigonometric functions.We know that sec C = 1/cos C
Hence the value of cos C = 4/9 .
Again we know that the value of sin C=1/cosec c
Therefore the value of cosec C is 9/√65 .

The Good Ole Times magazine charges for ads by the "column inch." A column inch is as wide as one column, and it is one inch high. The cost is $67 per column inch. How much would the magazine charge to print a 2 ½-inch ad?
Cost of the ad is $167.5
What is cost?
A cost is the worth of money that has been used up to create something or supply a service and is thus no longer accessible for use in production, research, retail, or accounting. In business, the cost might be one of acquisition, in which case the money spent to obtain it is recognized as cost. In this situation, money is the input that is used to purchase the item. This acquisition cost might be the total of the original producer's production expenses and the acquirer's additional transaction costs over and above the amount paid to the producer. Typically, the price includes a profit margin above the cost of manufacture.
The cost of the ad per column inch = $67
So, the cost of 2¹/₂ inch = 67 x 2¹/₂ = $167.5

strawberries and 3 pounds of apples? How many
pounds of fruit does she buy if she buys x pounds of
strawberries and y pounds of apples?
Answer:
Answer bellow with explanations
Step-by-step explanation:
if Miriam buys 0.5 pounds of strawberries and 3 pounds of apples she will in total would have bought 3.5 pounds of fruit.
if you are looking for the price she had to pay for the fruits above the equation to solve that is as following.
0.5 x 3$ = 1.5$
3.0 x 3.25 = 9.75$
total for the fruits needed above would be 1.5$ + 9.75$ = 11.25$
if you are looking for the amount of pounds converted into the amount of fruit
0.5/3$ = 0.16(6) pounds of strawberries
3/3.25$= 0.92307692307 pounds of apples
total of pounds of fruit that have been purchased is equal to 0.16(6) + 0.92307692307 = 1.08974358973 pounds

Answer:
21 Degrees.
Step-by-step explanation:
It was 22 degrees by noon, by then the temperature had already risen by
eight degrees, but since we are going back in time, we would subtract the eight degrees.
22 - 8 = 14.
Now we are at 9 A.M, it is 14 degrees. But, the temperature had doubled from 5-9 A.M, so we would divide our fourteen by two in order to half it.
14 ÷ 2 = 7.
Now we are at 5 A.M.
From midnight to 5 A.M the temperature dropped fourteen degrees so we would add that fourteen back into the equation.
7 + 14 = 21.

use left and right endpoints and the given number of rectangles to find two approximations of the area of the region between the graph of the function and the x-axis over the given interval.
The two approximations of the region's area between the graph of the function and the x-axis over the given interval are 14.31 < AREA < 17.01
We have :

Here, a = 2 and b = 4 , n = 6
The width of the rectangles will be
x' = [tex]\frac{b-a}{n}[/tex]
x' = [tex]\frac{4-2}{6} = \frac{2}{6} = \frac{1}{3} = 0.33[/tex]
Now, The given function is f(x) = 9 -x
[tex]f(x_{i}) = x_{i} - 9[/tex]
For [tex]x_{0} = 0[/tex], [tex]f(x_{0} ) = 9[/tex]
For [tex]x_{1} = 0.3[/tex], [tex]f(x_{1} ) = 9 -0.3 = 8.7[/tex]
For [tex]x_{2} = 0.6[/tex], [tex]f(x_{2} ) = 9 -0.6 = 8.4[/tex]
For [tex]x_{3} = 0.9[/tex], [tex]f(x_{3} ) = 9 -0.9 = 8.1[/tex]
For [tex]x_{4} = 1.2[/tex], [tex]f(x_{4} ) = 9 -1.2 = 7.8[/tex]
For [tex]x_{5} = 1.5[/tex], [tex]f(x_{3} ) = 9 -1.5 = 7.5[/tex]
For [tex]x_{6} = 2.1[/tex], [tex]f(x_{3} ) = 9 -2.1 = 7.2[/tex]
Now, The area by using an approximation using 6 approximating rectangles and right endpoints is given by.
A = Sum of [tex]f_{i}x'[/tex] = [tex](f_{1} + f_{2} + f_{3} + f_{4} + f_{5} + f_{6})x'\\[/tex]
A = (8.7 + 8.4 + 8.1 + 7.8 + 7.5 + 7.2)*0.3

A = (9+8.7 + 8.4 + 8.1 + 7.8 + 7.5 + 7.2)*0.3

The value of a, b, c and d are 25, 3, 14 and 7 such that the sum of all rows, columns and diagonals are 48.
Given to us a magic square in which the sum of all rows, columns and diagonals are same. Then, we have to complete the missing numbers i.e., a, b, c and d respectively.
Let's proceed to solve this magic square accordingly.
First let's calculate that what will be the sum of all rows, columns and diagonals.
From the figure of magic square one diagonal is completely filled from that we can easily calculate the sum of the diagonals.
Sum = 5+16+27 = 48
Then, we can find the value of a, b, c and d easily.
5+a+18 = 48
23+a = 48
a = 48-23
a = 25
Therefore, the value of a is 25.
29+16+b = 48
45+b = 48
b = 48-45
b = 3
Therefore, the value of b is 3.
Now, 5+29+c = 48
34+b = 48
c = 48-34
c = 14
Therefore, the value of c is 14.
Then, we have
c+d+27 = 48
14+d+27 = 48
41+d = 48
d = 48-41
d = 7
Therefore, the value of d is 7.
Hence, we have completed the magic square in which the sum of all rows, columns and diagonals are 48.
Therefore, the value of a, b, c and d are 25, 3, 14 and 7 respectively.
