Answer:
[tex]x = -0.8\ or\ x = 0.5[/tex]
Step-by-step explanation:
Given [Missing from the question]
[tex]6x^2 + 2x - 2.5 = 0[/tex]
Required
Solve
Using factorization, we have:
[tex]6x^2 + 2x - 2.5 = 0[/tex]
Expand 2x
[tex]6x^2 - 3x+5x - 2.5 = 0[/tex]
Factorize
[tex]3x(2x - 1)+2.5(2x - 1) = 0[/tex]
Factor out 2x - 1
[tex](3x +2.5)(2x - 1) = 0[/tex]
Split:
[tex](3x +2.5) = 0\ or\ (2x - 1) = 0[/tex]
In both cases, solve for x
[tex]3x = -2.5\ or\ 2x = 1[/tex]
[tex]x = -\frac{2.5}{3}\ or\ x = \frac{1}{2}[/tex]
[tex]x = -0.8\ or\ x = 0.5[/tex] --- approximated

Answer:
11 grams
Step-by-step explanation:
First convert 20,000 mg to grams = 20 g
Add the amount of fiber she ate so
4+5=9
subtract that from the total
20-9= 11
Answer:
11 more grams of fiber
Step-by-step explanation:
So in one gram there are 1,000 mg, so you do 20,000 ÷ 1,000 to get that the recommended amount of fiber is 20g. We also know that she had 4 + 5 grams of fiber which is 9, so we do 20 - 9 to get 11. Therefore she needs to have 11 more grams of fiber.

Answer:
(a) 6.01 (b) 57.33
Step-by-step explanation:
(a) DF² = 10² + 12² - 2 · 10 · 12 · cos(30°)
=> DF² = 244 - 240 · cos(30°)
=> DF² = 36.154
=> DF = √36.154
=> DF ≈ 6.01
(b) [tex]\frac{12.8}{sin(63)} = \frac{12.4}{sin (B)}[/tex]
=> sin (B) = sin (63) × 12.4 ÷ 12.8
=> B = sin^-1 (sin (63) × 12.4 ÷ 12.8)
=> B = 59.67355245
180 - 63 - 59.67355245 ≈ 57.33

Answer:
This is irrational. Pretty much anything with pi is irrational.
Step-by-step explanation:
Pi is irrational, so this irrational as well.
Answer:
The number π is an irrational number, so it cannot be expressed as a fraction. Since π is irrational, it follows that π/2 is also irrational.
The lengths of two sides of a triangle are 24 inches and 43 inches. What is the range of the possible lengths, in inches, for the third side, x, of this triangle?
Answer:
19 < x < 67
Step-by-step explanation:
triangle inequality theorem:
x + 24 > 43
43 + 24 > x
The range of the possible lengths, in inches, for the third side, x, of this triangle with two sides of a triangle are 24 inches and 43 inches is,
⇒ 19 < x < 67
What is mean by Triangle?Any triangle which is a three sided polygon, and, has three vertices and three angles which has the sum 180 degrees.
We have to given that;
The lengths of two sides of a triangle are,
⇒ 24 inches
And, 43 inches.
Hence, The range of the possible lengths, in inches, for the third side, x, of this triangle is find as;
⇒ 43 - 24 < x < 43 + 24
⇒ 19 < x < 67
Therefore, The range of the possible lengths, in inches, for the third side, x, of this triangle with two sides of a triangle are 24 inches and 43 inches is,
⇒ 19 < x < 67

Answer: x=133
Step-by-step explanation:
This is a hexagon that has a total of 720 degrees (which you can get by the formula of degrees = (# of sides – 2) * 180).
You first add up all your side:
150+130+97+120+90 +x = 587 + x
587+x = 720
x=133
Jeremy bought a $60 pair of sneakers on sale for 15% off. Then, he used a coupon that gave him an additional 10% off. Can Jeremy find the cost of the sneakers by adding the percents? Justify your answer:
-by finding 25% off of $60, and
-by finding 15% off of $60, and then subtracting 10% from that cost.
Use the drop-down menus to complete your explanation.
---------------------------------------------------------------------------------------
Jeremy cannot/ can find the cost by adding the percents.
.
25% off of $60 is equal to $45.00/35.00/25.00/45.90
.
15% off of $60, then subtracting 10% from that cost is equal to 35.00/25.00/38.25/45.90...
.
The two total costs are equal/not equal
can someone help me solve this question pls?
Answer:
No, Jeremy can not find the cost of the sneakers by adding the percents, you have to math one sale discount at a time.
The answer is $45.90.
Step-by-step explanation:
You have to multiply $60 by 15%, getting $9. Subtract 9 from 60 and get the first discount price: $51. Then you will multiply 51 by `10% and get 5.1, subtract 5.1 from 51 and get your final sale price of $45.90. If you added the percents together you would get an incorrect value of $45. Close but not the correct answer.

The volume V of a cone varies jointly as the area of the base B and the height
h. V = 32 cm, when B = 16 cm2 and h = 6 cm. Identify h when
V = 60 cm3 and B = 20 cm2.
Answer:
h = 9 cm.
Step-by-step explanation:
V = kBh where k is the constant of variation.
From the given info:
32 = k*16*6 = 96k
So k = 32/96 = 1/3.
So we have the equation of variation:
V = 1/3Bh
When V = 60 B = 20, so:
60 = 1/3 20h
20h = 60 * 3 = 180
h = 180 /20 = 9.
Find the volume of the composite figure below.
Answer:
Volume of composit figure= 4834.14 cm^3
Step-by-step explanation:
here's your solution
=> Radius of hemisphere = 9 cm
==> volume of hemisphere = 2/3πr^3
==> volume of hemisphere = 2/3*22/7* 9^3
==> volume = 1526.04 cm^3
=> Radius of cylinder = 9 cm
=> Height of cylinder = 13 cm
==> volume of cylinder = πr^2h
==> volume of cylinder = 22/7*9^2*13
==> volume of cylinder = 3,308.1 cm^3
Volume of composit figure = 1526.04 + 3308.1
= 4834.14 cm^3

Step-by-step explanation:
(1) We are shown that two angles and one side are congruent in the order of AAS. Make sure you write the letters in terms of the corresponding angles. The angles and sides are congruent because the problem labels it for us. For example, B,A,C=R,Q,S. Answers: AAS, RQC.
(2) We are shown that two angles and one side are congruent in the order of ASA. Make sure you write the letters in terms of the corresponding angles again. For example, P,Q,R=P,S,R. The angles are congruent because the problem labels it for us. Side PR is congruent to side PR by reflexive property. Answers: ASA, SRP.

Let’s say you want to play a new card game called Pokee. Every player is dealt 4 cards and everyone compares what hands they have to see who wins. Our job is to figure out what the hierarchy of the hands should be. Below is a list of several scoring hands that we wish to compare. For each hand, count how many hands of that type there are (include the expression you used to get that value) along with a simple explanation of how you got that expression. Assume a standard 52 card deck with 4 suits.
a) Presidential Flush (J, Q, K, Ace, all the same suit)
b) Straightish (4 consecutive cards)
c)Flushed (4 cards of the same suit)
d) House (Two pairs of different cards)
