Answer:
152 grams of zinc
Step-by-step explanation:
You can always first create some ratios to clean it up
[tex] \frac{zinc}{copper} = \frac{4}{19} = \frac{x}{722} [/tex]
x being zinc, what we need to find
Next we can cross multiply
[tex]19x = (722)(4)[/tex]
[tex]19x = 2888[/tex]
Lastly, we will divide both sides by 19 to get X alone.
[tex]x = 152[/tex]

What is the area of this trapezoid?
Enter your answer in the box.
Answers
Answer:
153 units squared
Step-by-step explanation:
first, multiply 10 x9 to find the area of the rectangle, which is 90
then find the area of the triangle. The formula for area of a triangle is
A=1/2bh
so, 7 x 9= 63 divided by 2 is 31.5
since there are 2, multiply 31.5 x 2= 63
add 63 to 90 which is 153
Answer: 153 sq. units
Step-by-step explanation:
Base a = 10
Base b = 7x2 = 24
Height = 9
area of trapezoid = 1/2 * (a+b) * h
= 10+24 * 9 /2
= 306/2 = 153

Answers
The options b and d are suitable equations. The equations are [tex]\frac{1}{2} m+4=20 and 4=20-\frac{1}{2}m[/tex]. The number of students in Bryan's homeroom in this equation is m.
The following information is given in the question: The number of students who possess tickets = 20. And, m is the number of students in Bryan's homeroom. let us solve the sum using this particular equation [tex]\frac{1}{2} m+4=20[/tex] to figure out how many students are in Bryan's homeroom.
On solving the given equation,
[tex]\frac{1}{2} m+4=20 \\4+\frac{2}{m} = 20\\8+m=40\\m= 40-8 = 32. \\[/tex]
As a result, there are 32 students in Bryan's homeroom(m). The options that are used to find the number of students, m, in Bryan’s homeroom are [tex]\frac{1}{2} m+4=20[/tex] and [tex]4=20-\frac{1}{2}m[/tex]. All other options do not satisfy the conditions given in the question.

Hii, does anyone know what the variables equal?
Answers
Answer:
a. 5d * 7g = 35dg
b. 12ab * 3cd = 36abcd
Step-by-step explanation:
To find the product of two or more terms, we can use the distributive property of multiplication. In part (a), we multiply the coefficients 5 and 7 to get 35, and we multiply the variables d and g to get dg. Therefore, the product of 5d and 7g is 35dg.
In part (b), we can multiply the coefficients 12 and 3 to get 36, and we can multiply the variables a, b, c, and d to get abcd. Therefore, the product of 12ab and 3cd is 36abcd.
Answer:
In these scenarios, it is not possible to find the values of the variables and the question is not asking you to do so
a. 5d x 7g = 35dg
b. 12ab x 3cd = 36abcd

Maria’s current car gets 24 miles per gallon. Last year she drove 15,000 miles. Last year gas cost an average of $3.35
solve 1. How much did Maria spend for gas for her car last year?
solve 2. Maria is buying a new car that averages 32 miles per gallon. If she drives the car 15,000 miles in the next year and gas prices stay the same, how much will she spend for gas in the next year?
solve. 3 ) How much money will Maria save in gas costs in the next year by driving her new car as opposed to her old one?
solve 4. What percent decrease in gas costs for one year will Maria realize by driving her new car?
Answers
1) Last year, Maria spent $2093.75. Here's the equation to find that answer:
(a ÷ b) × c
a = 15,000b = 24c = 3.35(15,000 ÷ 24) × 3.35
2) Same equation. (15,000 ÷ 32) × 3.35. The answer of this equation is 1570.3125, but that rounds to $1570.31.
3) This part represents a simple difference/subtraction problem. Since she spent $2093.75 last year, and will spend $1570.31 with a new car, she will save 523.44.
4) Using percent of change, the percent decrease Maria will realize in one year is 33.333%, or [tex]\frac{1}{3}[/tex].

All triangles have a sum degree measure of 180.
We know ∠B, which is 39.8.
∠A is known as well, the little box at the corner indicates a right angle, which means it has a degree of 90.
To find ∠C, we can construct a formula to find the unknown value.
1. 180 = ∠A + ∠B + ∠C Isolate ∠C.
2. 180 - ∠A - ∠B = ∠C
3. 180 - 90 - 39.8 = ∠C
4. 50.2 = ∠C
Therefore, angle C is 50.2 degrees. The other information is written to throw you off.
