3. Which of these will DEFINITELY be true about any number between -35 and -15? (A) It will be equal to -25. (B)It will be less than -20. (c) It will be more than -10. (D)It will be less than -10
Answer:
(A) It will be equal to -25
Step-by-step explanation:
Given a number between -35 and -15.
To find:
A statement always true about the number.
(A) It will be equal to -25.
(B)It will be less than -20.
(c) It will be more than -10.
(D)It will be less than -10
Solution:
First of all, let us represent the given numbers on number line.
Please refer to the attached diagram for the number line representation of the numbers.
When we move towards left from 0, the numbers decrease.
Therefore, -15 is a value greater than -35.
-15 > -35
When we move towards right from 0, the numbers increase.
So, statement "A)It will be equal to -25" is true.
-25 will always be in between -15 and -35.
Option B:
Less than -20.
-40 is also lesser than -20 but is not in between -35 and -15.
So not true.
Option C:
More than -10.
-8 is also more than -10 but not in between -35 and -15.
So not true.
Option D:
Less than -10.
-11 is also lesser than -10 but is not in between -35 and -15.
So not true.

1/9 as a percent? Rounded to the nearest hundreth.
Answer:
11.11%
Step-by-step explanation:
We can first convert the fraction [tex]\frac{1}{9}[/tex] into a decimal.
We know that a number over 9 will be 0.(that number repeating), for example, [tex]\frac{4}{9}[/tex] is 0.444444...
So this means that [tex]\frac{1}{9}[/tex] will be 0.11111...

At first, you might think that -5 is bigger than -2 because 5 > 2, right? Actually, no, that's not how it works. The "rules" for numbers are flipped when you are dealing with negative numbers, so therefore, -2 is bigger. Basically, what I'm saying is that the smaller the number after the negative sign, the bigger the number is and vice versa.

HELP WILL GIVE 40 POINTS AND BRAINLIEST!!!! Solve these two (second-degree) quadratic equations by factoring. [tex]2x^{2}+6x=0[/tex] & [tex]x^{2}+9x+14=0[/tex]
Answer:
Step-by-step explanation:
First equation: 2x^2 + 6x = 0 factors into 2x(x + 3) = 0, so either x = 0 or x = -3.
Second equation: x^2 + 9x + 14 = 0 factors into (x + 2)(x + 7) = 0. Thus, either x = -2 or x = -7
Hi there! Hopefully this helps!
---------------------------------------------------------------------------------------------------------
Answer for [tex]2x^{2} + 6x = 0[/tex]: x = 0x = -3|
|[tex]2x^{2} + 6x = 0[/tex]
|
|First we factor out x
\/
[tex]x(2x+6)=0[/tex]
To find equation solutions, solve [tex]x = 0[/tex] and [tex]2x+6 = 0[/tex]
|
\/
[tex]x = 0[/tex]
[tex]x = -3[/tex]
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Answer for [tex]x^{2}+ 9x + 14 = 0[/tex]:x = -2x = -7|
|
|[tex]x^{2}+ 9x + 14 = 0[/tex]
|
|To solve the equation, factor [tex]x^{2}+ 9x + 14[/tex] using formula [tex]x^{2} + (a + b)x + ab = (x+a) (x+b).[/tex] To find [tex]a[/tex] and [tex]b[/tex], set up a system to be solved.
|
\/
[tex]a + b = 9[/tex]
[tex]ab = 14[/tex]
|
\/
Since [tex]ab[/tex] is positive, [tex]a[/tex] and [tex]b[/tex] have the same sign. Since [tex]a + b[/tex] is positive, [tex]a[/tex] and [tex]b[/tex] are both positive. List all such integer pairs that give product 14.

Answer:
Not enough tables.
Step-by-step explanation:
Circumference is 2*pi*r
The diameter is 2 times the radius or 2r, if the table diameter is 180cm. All we need to do is multiply by pi (3.14159) to get the circumference.
180*pi = 556.48cm
If each guest needs 70cm then we divide the circumference by 70
556.48/70 = 8.08 but we cant have a portion of a person so we can fit 8 people per table.
18 tables with 8 at a table is 8 x 18 = 144
If 145 guests are attending then there aren't enough tables, you are 1 table short.
Problem IDPRAQT48 At the beginning of a trip, a car's gasoline tank contained 14 1/5 gallons of gas. At the end of the trip, it contained 8 2/3 gallons. How many gallons of gas did the car use?
Answer:
5 8/15 Gallons
Step-by-step explanation:
Step 1: Change mixed numbers into improper fractions.
14 1/5 = 71/5
8 2/3 = 26/3
Step 2: Change the improper fractions to have the same denominator.
71/5 = 213/15
26/3 = 130/15
Step 3: Subtract
213/15 - 130/15 = 83/15
Step 4: Simplify
83/15 = 5 8/15

OC. 28
D.

Answer:
Option C. 28
Step-by-step explanation:
From the question given,
m<HKM = 155°
m<JKL = (5x + 15)°
From the diagram,
m<HKM = m<JKL (since they are directly opposite)
Inputting the value of m<HKM and m<JKL into the above expression, we have:
m<HKM = m<JKL
m<HKM = 155°
m<JKL = (5x + 15)°
155 = 5x + 15
Collect like terms
155 – 15 = 5x
140 = 5x
Divide both side by 5
x = 140/5
x = 28
Therefore, the value of x is 28.

The ratio of the numerator and denominator of a rational number is 2 : 7 and
if 4 is added to the numerator and 2 is subtracted from denominator, the
rational number becomes 10
19
. Find the original rational number.
Answer:
6/21.
Step-by-step explanation:
let the rational number be 2x/7x.
2x + 4 / 7x - 2 = 10 /19
Cross multiply:
19(2x + 4) = 10(7x - 2)
38x + 76 = 70x - 20
96 = 70x - 38x
32x = 96
x = 3.
So the rational number is 2*3/ 7*3

75% of the M&Ms in a bag are red. There are 36 red in the class. How many M&M the
bag?
Answer:
48
Step-by-step explanation:
Let x be the total number of M&Ms in the bag.
0.75x = 36 because 75% of the M&Ms are red and there are 36 red M&Ms.
We can divide both sides by 0.75, getting x = 48.
Therefore, there are 48 M&Ms in the bag.
Given point P (3, 4). What is the distance of point P from (a) x axis (b) y axis?
Answer: Hi!
To find the distance of the point from each axis, all we have to do is look at the x and the y coordinates of the points. If we wanted to find the distance that point P was from the x axis, we would look at our y - coordinate:
(x, y) = (3, 4) So, point P is 4 units away from the x -axis.
Now we need to look at the x - coordinate to find the distance that point P is from the y axis:
(x, y) = (3, 4) So, point P is 3 units away from the y - axis.

Answer:
BC = 1/2 AC
2m angle DBC = m angle ABC
Angle ABC is bisected by ray BD
m∠WUT = 38°
Step-by-step explanation:
For both questions, we use the Angle Bisector Theorem.
Question 1:
We know since ray DB bisects ABC, AB and BC are congruent. They are split into 2 equal parts. Therefore, we know that if we take half of mAC, we should get either mBC or mAB. Therefore, the 1st statement is correct.
Since it is ray DB bisecting ABC, it created 2 right angles. If angle DBC was bisected, it would create 2 new angles that were 45° each, so the 2nd statement is incorrect.
We know that line ABC is equal to 180°. So if we add m∠ABD and m∠DBC (they both are 90°, as denoted in the picture) together, we should get 180°. Also, since they are congruent angles, one angle multiplied twice would also be 180°. Therefore, the 3rd statement is correct.
The Angle Bisector Theorem doesn't state that the bisector and one segment would be congruent. The length of the bisector could be anything and is not marked congruent to the other segments. Therefore, the 4th statement is incorrect.
Since we see that there is a bisector DB bisecting line ABC, creating 2 congruent segments and angles, we know that the 5th statement is correct.
Question 2:
The Angle Bisector Theorem states that a bisector that bisects 2 angles will become 2 smaller but congruent angles. So,
Step 1: Find x
4x + 6 = 6x - 10
6 = 2x - 10
16 = 2x
x = 8
Step 2: Find m∠WUT
m∠WUT = 6x - 10
m∠WUT = 6(8) - 10
m∠WUT = 48 - 10
m∠WUT = 38°
