A student made an 85% on a test with 25 questions. What is the number
of questions that the student answered correctly? Round to the nearest
whole number*
The student answered 21 questions correctly on a test.
What is the Multiplication operation?In mathematics, Multiplication operations perform Multiplying values on either side of the operator.
For example 4×2 = 8
Since the student made an 85% on a test with 25 questions.
To determine the number of questions the student answered correctly, we need to multiply the number of questions by the percentage of questions answered correctly, which is 85%.
= 25 questions × 0.85
Apply the multiplication operation, and we get
= 21.25
Rounding to the nearest whole number,
= 21 questions
Thus, the student answered 21 questions correctly.

Frank designed a net for a storage shed that he is going to construct out of metal. The design consists of a square base and four square sides, plus four triangular parts that make up the roof.
He had 250 square feet of metal to use to build the shed. (What is the surface area of the storage Shed that Frank Designed?) (Does Frank have enough metal to construct his design yes or no?)
Answer:
Yes, Frank does have enough, he has 250 metal and only has 228 surface area.
Step-by-step explanation:
You take all the triangles (4) and multipy 4 x 6 (24) then divide that by 2 (12) so now you know all the triangles are equal to 12. Then the squares, you multiply 6 x 6 (36) now you know all the squres are equal to 36 and then you add 12 + 12+12+12+36+36+36+36+36 and then you get 228.

What are the measures of the other three angles formed by the intersection?
Answer:
1 = 130
2 = 50
3 = 130
Step-by-step explanation:
Since we already know that one angle is 50 degrees, this also tells us that angle two is congruent to it because it is opposite to it. Now the two other adjacent angles, basically just do 180-50 to get 130.

Victor sold cupcakes and cookies yesterday. Each cupcake sold for $2.25 and each cookie sold for $0.50. At the end of the
day, Victor had sold $95.25 worth of cookies and cupcakes. If he sold 68 cupcakes and cookies combined, how many
cupcakes were sold and how many cookies were sold?
answer:number of cupcakes sold is 13 Number of cookies sold is 27
Step-by-step explanation:
Let x represent the number of cupcakes that Victor sold. Let y represent the number of cookies that Jane sold. Each cupcake sold for $2.25 and each cookie sold for $0.50. At the end of the day, This mean Victor had 2.25x 0.5y = 42.75 - - - - - - - - - -1she sold 40 cupcakes and cookies combined, it means thatx y = 40Substituting x = 40 - y into equation 1, it becomes2.25(40 - y) 0.5y = 42.7590 - 2.25y 0.5y = 42.75- 2.25y 0.5y = 42.75 - 90- 1.75y = - 47.25y = - 47.35/-1.75y = 27x = 40 - yx = 40-27 = 13
An equation is formed when two equal expressions. The number of cupcakes that Victor sold is 35, while the number of cookies that Victor sold is 33.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the number of cupcakes sold be represented by x, while the number of cookies sold is represented by y.
Now, the total number of cupcakes and cookies sold combined is equal to 68. Therefore, the equation can be written as
x + y = 68
x = 68 - y
Also, Each cupcake sold for $2.25 and each cookie sold for $0.50. And the total sale that Victor made is of $95.25. Therefore, the equation can be written as,
2.25x + 0.50y = 95.25
2.25(68 - y) + 0.5y = 95.25
153 - 2.25y + 0.5y = 95.25
-2.25y + 0.5y = 95.25 - 153
1.75y = 57.75
y = 33
Now, substitute the value of x in the first equation.
x + y = 68
x + 33 = 68
x = 35
Hence, the number of cupcakes that Victor sold is 35, while the number of cookies that Victor sold is 33.

3x+5=5x-29
5=2x-29
34=2x
Therefore x=17!
Answer:
x = 17
Step-by-step explanation:
Lets start evaluating
3x + 5 = 5x - 29
3x + 5 + 29 = 5x
3x + 34 = 5x
34 = 5x - 3x
34 = 2x
x = 34/2

Answer:
135degrees
Step-by-step explanation:
Find the diagram attached.
Note that in a cyclic quadrilateral, the sum of the opposite side of the quadrilateral is 180degrres.
According to the diagram shown:
<D+<I = 180
<D+45 = 180
Subtract 45 from both sides
<D+45-45 = 180-45
<D = 180-45
<D= 135°
Hence the measure of <D is 135degrees

What is the slope of (-6, 1) and (2,5)?
Answer:
1/2
Step-by-step explanation:
To find the slope given two points, use the slope formula
m= ( y2-y1)/(x2-x1)
= ( 5-1)/(2--6)
= (5-1)/(2+6)
= 4/8
= 1/2
Answer:
slope = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (2, 5)
m = [tex]\frac{5-1}{2+6}[/tex] = [tex]\frac{4}{8}[/tex] = [tex]\frac{1}{2}[/tex]

What is the weight of a square if a triangle weighs 4 grams? Explain your reasoning
Answer:
2 grams
Step-by-step explanation:
One can see that the given diagram is that of a balancing scale, meanig that both sides are equal to each other. Therefore, if one calls the weight of the triangle (t), then one can form an equation. Keep in mind that it is given that the square weighs (4) grams, and therefore, the square doesn't need a variable representation.
t + 4 + 4 = t + t + t + 4
Simplify,
t + 8 = 3t + 4
Inverse operations,
t + 8 = 3t + 4
-4 -4
t + 4 = 3t
-t -t
4 = 2t
/2 /2
2 = t
Answer:
2 grames

How does this create two “congruent” right angle triangles when i thought it had to be similar in 3 ways to be congruent
Though these segments aren't marked congruent in the diagram, the two lines inside the circle making up the bases of the triangles are congruent as all radii are congruent. So the triangles are congruent by SAS.
