You’re taking an exam in math, and you spend 5 minutes for every 2 questions you answer on the test.(Plz answer! I’m failing and I need to get this correct!)
Answers
Given:
Time spend on every 2 questions = 5 minutes.
To find:
The missing values for the given table.
Solution:
Let x be the number of questions and y be the number of minutes.
We have,
Time spend on every 2 questions = 5 minutes
Time spend on 1 question = [tex]\dfrac{5}{2}=2.5[/tex] minutes
Time spend on x questions = [tex]2.5x[/tex] minutes
Now,
[tex]y=2.5x[/tex]
For x=0,
[tex]y=2.5(0)=0[/tex]
For x=1,
[tex]y=2.5(1)=2.5[/tex]
For x=2,
[tex]y=2.5(2)=5[/tex]
For x=3,
[tex]y=2.5(3)=7.5[/tex]
For x=4,
[tex]y=2.5(4)=10[/tex]
Therefore, the required table is
Questions : 0 1 2 3 4
Time (minutes) : 0 2.5 5 7.5 10

supplementary
Find the ma

a
40 degrees
140 degrees
35 degrees

Answers
Step-by-step explanation:
Since the 2 angles are supplementary,
(7x + 5°) + 28x = 180°.
=> 35x + 5° = 180°
=> 35x = 175°
=> x = 5°.
Hence Angle A = 7(5°) + 5° = 40°.

2.25 inches
Step-by-step explanation:
400+400 is 800 then 1/4 is .25 so that would make it 100 out of the 400 add that to 800 = 900 so its 2.25 inches

Answers
Answer:
x = 34.06
Step-by-step explanation:
The sum of angles in the triangle LUV is 180 degrees
Given
∠L=(3x+y)°
∠U=42.6°
∠V=(4x−3y−0.8)°
Since ∠L+∠U + ∠V = 180 degrees
Substitute:
3x+y + 42.6 + 4x - 3y - 0.8 = 180
7x - 2y - 41.8 = 180
7x - 2y = 221.8 ... 1
Since UV = UL, hence the triangle is isosceles and <V = <L
3x+y = 4x-3y - 0.8
-x +4y = -0.8
x - 4y = 0.8 ....2
From 2: x = 0.8+4y
Substitute into 1:
7x - 2y = 221.8
7(0.8+4y) - 2y = 221.8
5.6 + 28y-2y = 221.8
26y = 221.8-5.6
26y = 216.2
y = 8.32
Get x
x = 0.8+4y
x = 0.8+4(8.32)
x = 0.8 + 33.26
x = 34.06
Note that it was assumed that <V = <l since the question is not clear

Find the volume, in cubic feet, of the composite solid below, which consists of a pyramid sitting on top of a cube. The pyramid has the same base as the cube.
Answers
Answer:
2,112 ft³
Step-by-step explanation:
Volume of composite solid = volume of pyramid + volume of cube
✔️Volume of square pyramid = ⅓(a²)*h
Where,
a = 12 ft
h = 8 ft
Plug in the values
Volume of pyramid = ⅓(12²)*8 = 384 ft³
✔️Volume of cube = a³
Where,
a = 12 ft
Plug in the value
Volume of cube = 1728 ft³
✔️Volume of composite solid = 384 + 1728 = 2,112 ft³

Answer:
hmm ..
just transfer the X at the right side and others on left side
Step-by-step explanation:
so you get
w-z = yx
so later
(w-z)/y = x
The required value of x for the equation w - yx = z is (w - z)/y.
What is an equation?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
The given equation is,
w - yx = z
Solve to determine the value of x,
Subtract w from both the sides,
w - yx - w = z - w
-yx = z - w
Multiply with -1 both the sides,
yx = w - z
⇒x = (w - z)/y
The value of x for the given equation is (w - z)/y.

Answers
Answer:
(-2, 8)
Step-by-step explanation:
To express any given inequality, note the following:
✔️< or > means the end value or the beginning value referred to is not included.
✔️ ≤ or ≥ indicates that the end of beginning value is included.
✔️ "( )" when used in writing an inequality in interval notation means an end or beginning value is not included.
✔️. "[ ]" means the end or beginning value is included.
Now let's express -2 < x < 8 using interval notation.
✅The beginning value is -2, which is < x. This means -2 is not included. Therefore, we would start our interval notation by stating this as: "(-2"
✅The end value is 8. x < 8. The "<" sign means 8 is not included. Thus, this statement would be expressed in interval notation as "8)"
✔️Combining both together, the inequality is experessed in interval notation as (-2, 8)

Answers
Answer:

Step-by-step explanation:
Lindsey had 400 tarts to start with, then she sold off 3/5 of them. Hence find the number of tarts left (2/5 of the original amount). Then she sold 1/4 of the remaining tarts. Therefore, find 1/4 or 2/5 of 400. The equation would be;
