The required number of coins are would only by quarters so that 12 coins shows the values of $3.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
dime = $0.1
quarter = $0.25
Now,
Let the number of dimes be x and number of quarter be y,
x + y = 12
x = 12 - y - - -- -(1)
According to the question,
0.1x + 0.25y = 3 -- - -(2)
y = 12
Now,
x = 0
Thus, the required number of coins are would only by quarters so that 12 coins shows the values of $3.

a^2 + b^2 = c^2
4^2 + 3^2 = c^2
16 + 9 = c^2
25 = c^2
do the square root of 25 and c to solve for c
the square root of c^2 is c
therefore, c= 5cm

Lebron James's Free Throw % is 75%
What is the probability that he makes 6 Free Throws in a row?
Answer as a decimal rounded to 2 places.
Answer: 0.18
Step-by-step explanation:
From the question, we are informed that Lebron James's Free Throw % is 75%. The probability that he makes 6 Free Throws in a row would be gotten by multiplying 75% six times. This will be:
= 75% × 75% × 75% × 75% × 75% × 75%
= 3/4 × 3/4 × 3/4 × 3/4 × 3/4 × 3/4
= 729/4096

Answer:
wx = 116 /11
= 10.54
Step-by-step explanation:
plz follow me
Answer: 29
see in the picture, WX is the median of the trapezoid
=> WX = (ST + UV)/2
⇔ 7x + 8 = (10x + 5 + 8x - 1)/2
⇔ 7x + 8 = (18x + 4)/2
⇔ 7x + 8 = 9x + 2
⇔ 2x = 6
⇔ x = 3
with x = 3 => WX = 7.3 + 8 = 21 + 8 = 29

Two important ingredients for baking bread are yeast and flour. To make a loaf of bread of at most 30 servings, maintain a yeast to flour ratio of 1:200. If you're making a loaf of more than 30 servings, use a ratio of 1:180. If you're making 30 servings of bread and using 0.45 oz of yeast, how many ounces of flour do you need? If you're making 90 servings of bread and using 720 oz of flour, how many ounces of yeast do you need?
If you're making 30 servings of bread and using 0.45 oz of yeast, how many ounces of flour do you need? ANSWER=90
If you're making 90 servings of bread and using 720 oz of flour, how many ounces of yeast do you need? ANSWER=4
The flour that will be used for 30 servings is 0.90 oz, while the yeast that will be used for 90 servings is 90 oz.
Given to us
To make a loaf of bread of at most 30 servings, maintain a yeast to flour ratio of 1:200.
To make a loaf of bread of more than 30 servings, maintain a yeast to flour ratio of 1:180.
Ratio for 30 ServingsA.) If We are making 30 servings of bread and using 0.45 oz of yeast,
As it is given that for 30 servings we must maintain a yeast to flour ratio of 1:200, therefore,
[tex]\rm \dfrac{Yeast}{Flour} = \dfrac{1}{200}[/tex]
Using the ratio for 0.45 oz of yeast,
[tex]\rm \dfrac{0.45\ oz}{Flour} = \dfrac{1}{200}[/tex]
[tex]\rm {Flour} = 200 \times 0.45\ oz[/tex]
[tex]\rm {Flour} = 90\ oz[/tex]
Thus, we will use 90 oz of the flour for 0.45 oz of yeast to serve 30 people.
Ratio for 90 ServingsB.) If We are making 90 servings of bread and using 720 oz of flour,
As it is given that for more than 30 servings we must maintain a yeast to flour ratio of 1:180, therefore,
[tex]\rm \dfrac{Yeast}{Flour} = \dfrac{1}{180}[/tex]
Using the ratio for 720 oz of flour,
[tex]\rm \dfrac{Yeast}{720\ oz} = \dfrac{1}{180}[/tex]
[tex]\rm {Yeast} = \dfrac{720\ oz}{180}[/tex]
[tex]\rm {Flour} = 90\ oz[/tex]
Thus, we will use 90 oz of the flour for 0.45 oz of yeast to serve 30 people.
Hence, the flour that will be used for 30 servings is 0.90 oz, while the yeast that will be used for 90 servings is 90 oz.
