How many solutions does the following equation have?
4(y - 30) - 4y + 12
Choose 1 answer:
А
No solutions
Exactly one solution
Infinitely many solutions
Answer:
Infinite solutions
Step-by-step explanation:
After you distribute, you get -108. The equation doesn't have an equal sign, but I don't think that matters. For every possible value of y, you get the answer -108, so the answer is either infinite solutions, or no solutions, depending on what you are trying to get the equation to equal to.
If it's a typo, and the negative is supposed to be an equal sign, the answer is no solutions.

From the picture, we see that this boils down to finding the length of a side of a right triangle. The angle that we know about is 45^ and we know that the length of the side adjacent to the angle is 100 feet. We want to know about the length of the side that is opposite to the angle.
The tangent of an angle alpha is the ratio of the length of the opposite side to the length of the adjacent side

Answer:
The length of h is 3cm.
Step-by-step explanation:
You are looking for h. In order to find h you need the equation of area of a triangle, which is a=1/2bh. They give you base and they give you area. Plugging the numbers in, the equation is 7 7/8 cm^2= 1/2(5 1/4)(h). Now you solve by getting h by itself.
2(7 7/8 cm^2)= (1/2(5 1/4)(h))2
(15 3/4)/(5 1/4)= ((5 1/4)(h))/(5 1/4)
3=h
Answer:
The answer is h+ 3cm

Select all ordered pairs that satisfy the function
y=2/3x + 1
A. (-3,-1)
B. (-2,-1)
C. (3, 3)
D. (5, 6)
Answer:
its D
Step-by-step explanation:
The ordered pairs that satisfy the function y = 2/3x + 1are (-3,-1) and (3,3)
How to determine the ordered pairs?The function is given as:
y = 2/3x + 1
Next, we test the options
(a) (-3,-1)
This gives
-1 = 2/3 * -3 + 1
Evaluate
-1 = -1 --- this is true
(b) (-2,-1)
This is false because -1 = -1 is true in (a)
(c) (3,3)
This gives
3 = 2/3 * 3 + 1
Evaluate
3 = 3 --- this is true
(d) (5,6)
This gives
6 = 2/3 * 5 + 1
Evaluate
6 = 4.3 --- this is false
Hence, the ordered pairs are (-3,-1) and (3,3)

The lenght of a rectangle is 3 inches more then its width. Its perimeter is 42 inches, find the dimensions of the rectangle
Answer:
The problem uses the perimeter formula. P = 2w + 2l where w is the width, and l is the length.
We know the length (l) is 3 inches longer than it's width (or l = w+3). Substitute w +3 into Perimeter equation.
P = 2w + 2(w+3). That simplifies to P = 4w + 6.
Since P + 42, we have 42 = 4w +6. With some simple algebra we find that w = 9 and l = 12.

Calvin works at a clothing store. He sells 3 pairs of jeans for $66.49 each, 2 shirts $28.99 each, and a belt for $15.40. He also gives a refund for a coat that a customer returned for $89.95. What is the net change in the amount of money for the store?
Answer: 182 / 182.9
Step-by-step explanation:
199.47 +57.98 + 15.40 - 89.95
3 x 66.49 = 199.47
2 x 28.99 = 57.98
since there was only one for the belt and the coat there is no problems for that.
add and subtract all of that and you get 182 or 182.9

Adrian needs to be at school at 7:45 am. It takes him 15 minutes to walk to school, 512 hour to eat breakfast, 0.7 hour to get dressed, and 0.15 hour to shower. What time should he wake up.
Correct question:
Adrian needs to be at school at 7:45 am. It takes him 15 minutes to walk to school, 5/12 hour to eat breakfast, 0.7 hour to get dressed, and 0.15 hour to shower. What time should he wake up.
Answer:
Adrian should wake up by 6.14 am
Step-by-step explanation:
Given;
time to walk to school, = 15 mins
time to eat breakfast = 5/12 hour = 25 mins
time to get dressed = 0.7hour = 42 mins
time to shower = 0.15 hour = 9 mins
time Adrian needs to be in school = 7.45 am
Count from this time he needs to be at school backwards by subtracting the time he will spend before reaching school;
7.45 am - 15 mins = 7.30 am
7.30 am - 25 mins = 7.05 am
7.05 am - 42 mins = 6.23 am
6.23 am - 9 mins = 6.14 am
Therefore, Adrian should wake up by 6.14 am
Cup o' Coffee buys its coffee for $1.25 a cup. The coffee shop then sells each cup for $3.75. What is the percent markup for a cup of coffee?
Answer:
47%
Step-by-step explanation:
.375 × .125 = .046875
rounding up, 5 keeps the 7 as is, 7 is greater than 5, therefore the 8, becomes a 9, 9 is greater than 5, so the 6 becomes a 7, .047.
move the decimal three digits to the left and you get, 47%.
Percentage markup is the percent of the difference of the selling price to the buying price of a product. The percent markup for a cup of coffee is 200%.
The percentage markup has to be find out for the cup of coffee.
What is percentage markup?Percentage markup is the percent of the difference of the selling price to the buying price of a product. It can be given as,
[tex]M=\dfrac{\rm SP-C}{C} \times 100[/tex]
Here, [tex]SP[/tex] is the selling price and [tex]C[/tex] is the cost of the product.

A rectangle has length 6 and height 4. Which of these would tell you that quadrilateral ABCD is definitely not similar to this rectangle? Select all that apply.
Answer:

3) AB=8
4) BC=8
5) BC=2⋅AB
Step-by-step explanation:
A rectangle has length 6 and height 4.
Which of these would tell you that quadrilateral ABCD is definitely not similar to this rectangle? Select all that apply.
1) AB=BC
2) m∠ABC=105∘
3) AB=8
4) BC=8
5) BC=2⋅AB
6) 2⋅AB=3⋅BC
Answer:
A rectangle is a quadrilateral (has four sides). Opposite sides of a rectangle are equal to each other and the diagonals bisect each other. Also, each of the angles in rectangle measure 90°.
1) AB = BC
Opposite sides of a rectangle are equal, hence AB is opposite to CD and BC is opposite to AD. Therefore:
AB = CD, BC = AD
AB ≠ BC
2) m∠ABC = 105°
Each of the angles in a rectangle measure 90°, therefore m∠ABC = 90°. m∠ABC ≠ 105°
3) AB = 8
AB might be the length or height of the rectangle, hence:
AB = 6 or AB = 4. AB ≠ 8
4) BC = 8
BC might be the length or height of the rectangle, hence:
BC = 6 or BC = 4. BC ≠ 8
5) BC = 2AB
If BC is the height = 4, BC ≠ 2AB
6) 2AB = 3BC
If AB is the length of the rectangle and BC is the height of the rectangle then:
2(6) = 3(4)
12 = 12
2AB = 3BC

sin θ = 4 cos θ
Answer:
θ=arctan(4) or 75.96°
Step-by-step explanation:
sinθ=4cosθ (given)
sinθ/cosθ = 4cosθ/cosθ (divide both sides by cosθ)
sinθ/cosθ = 4 (cancel cosθ)
tanθ=4 (sin/cos is equal to tan)
θ=arctan(4)(transposing tan will give you arctan)
θ=75.96 (calculation will give you this)

without finding any other angles or sides congruent, determine which pair of triangles can be probed to be congruent by the HL theorem
Answer:
YXZ and NMO
Step-by-step explanation:
The HL (hypotenuse leg) theorem says that if the hypotenuse and one leg of one right triangle is congruent to the hypotenuse and one leg of another right triangle, the 2 triangles are congruent.
Therefore, we can see that the only 2 triangles that can be guaranteed to be congruent are triangles YXZ and NMO.
The radius of a circle is 7 feet . What is the circle's area?
Answer:
The circle's area is 153.93804 feet^2
Step-by-step explanation:
The formula for the area of a circle is [tex]a = \pi r^{2}[/tex]
Using this formula, input the number 7 in for "r" and solve:
a = pi ( 7 )^2
a = pi ( 49 )
a = 153.93804 feet^2
The area of the circle is 153.93804 feet^2. Round the number to the specified decimal point.

Write an expression that describes the length of a rectangle given that the width is 2z and the area is 16z^2 - 10z^2 + 2z
Answer:
3z + 1
Step-by-step explanation:
Area = 16z^2 - 10z^2 + 2z = 6z^2 + 2z = 2z(3z + 1)
Width = 2z
Area of a rectangle is given as:
Area = length × width
hence length = Area/Width
= 2z(3z + 1)/2z
= 3z + 1
