[tex] \sqrt{99 - ( - 1)} [/tex]
Answer:
10
Step-by-step explanation:
Note that when there are two negative signs directly next to each other, you are adding:
[tex]\sqrt{99 - (-1)} = \sqrt{99 + 1} = \sqrt{100}[/tex]
Simplify:
[tex]\sqrt{100} = \sqrt{10 * 10} = 10[/tex]
10 is your value for the given expression
Answer:
± 10Step-by-step explanation:
[tex]\sqrt{99 - (-1)} = \sqrt{99 + 1} = \sqrt{100}[/tex] = ± 107.You plan to show that triangle QRS is similar to triangle XYZ by the SSS Similarity Theorem. Complete the proportion that you will use:
What is 3 (2x + 4) = 12?
Answer:
Hi!!
The answer is = 0
Step-by-step explanation:
1. Distribute
3(2+4)=12
6+12=12
2. Subtract 12 from both sides of the equation
6 + 12= 12
6 + 12 − 12 = 12 − 12
3.Simplify
part A. 6 + 12 − 12 = 12 − 12
6x = 12 - 12
part B. 6x = 12 - 12
6x = 0
Hope this helps!! =)
Please show work! thank you :)
Answer:
c = 18
d = 36
Step-by-step explanation:
2c = d (equation 1)
c + d = 54 (equation 2)
Use substitution by putting 2c in the place of d on the second equation.
c + 2c = 54
3c = 54
Then divide both sides by 3 to get c (18).
Then use equation 1 to find d. Do this by putting 18 in the place of c.
2(18) = d
Solve, and the answer is d = 36

Four rays meet at a common endpoint. Find the value of x. Find the measurement of angle CAD, if angle BAC =60, DAE= 90 and angle BAE= 12x, CAD=3x
Answer:
x = 14
<CAD = 42degrees
Step-by-step explanation:
Since all the rays meet at a point, the sum of all the angles at the point will be 360 degrees, since angle at a point is 360degrees
Taking the sum of all the angles and equating to 360, we will have;
<BAC + <DAE + <BAE + <CAD = 360
60+90+12x+3x = 360
150 + 15x = 360
15x = 360 - 150
15x = 210
x = 210//15
x = 14
Get <CAD
Since <CAD = 3x
<CAD = 3(14)
<CAD = 42 degrees
Hence the measure of angle CAD is 42degrees

Joel borrowed $1,512. He was to pay that amount back along with an additional 9% interest. He could only pay back 82% of what he should have. How much did Joel pay back on his loan?
Answer:
$1351.43Step-by-step explanation:
The amount to pay:
$1512 + 9% = $1512*1.09 = $1648.08The amount paid back:
82% of $1648.08 = 0.82*1648.08 = $1351.43Choose the polynomial that is written in standard form.

6, 3, 7 - incorrect orderAnswer:
[tex] { - 3x}^{5} + {4x}^{3} + {10x}^{2} [/tex]
Step-by-step explanation:
For a polynomial to be in standard form, it must satify the conditions below:
1) It must not contain like terms
2) The exponents (powers) must be written in descending order
That is, the polynomial must be of the form
[tex]f(x) = {ax}^{n} + {bx}^{n - 1} + {cx}^{n - 2} + . \: . \: . \: . \: . \: mx + n[/tex]
Where a, b, c, m, n, are coefficients/constants
The only option that satifies the above conditions, and follows the pattern f(x) shown is:
[tex]{ - 3x}^{5} + {4x}^{3} + {10x}^{2} [/tex]

(50pts) The distance covered and the time taken by a car are plotted in a graph.
a. Find the slope of the line in the graph.
b. Calculate the distance traveled by the car at the 20th second.
c. Calculate the speed of the car.
Answer:
a=2
b=40m
c=2m/s
Step-by-step explanation:
slope is rise over run so 10/5 simplified is 2/1 or 2
for b just look at the graph at the 20th second
for c you do distance over time so basically the same thing as a 10/5 which is 2m/s

Answer:
48
Step-by-step explanation:
Since it's a right angle, it's automadically 90 degrees so you just have to add 23+ 19 and subtract from 90.
23 + 19 = 42
90 - 42 = 48

The distance travelled by a delivery vehicle can be calculated by the equation Distance = Rate x Time. What would be the correct representation of a situation in which a driver doubles his original speed, but drives for only of the original amount of time? dn = new distance do = original distance
Answer:
New distance = 2do
Step-by-step explanation:
The distance equation :
Distance = speed * time
If speed is doubled ; time stays the same
If speed is doubled,; new speed becomes
Doubled speed = 2* speed
Time remains the same ;
Hence,
New distance becomes : 2 * speed * time
Original dista, Speed * distance
New distance, dn = 2*do = 2do

Chris wants to create a rectangular rose garden in a yard. He has 48 meters of garden fencing to go around the garden and he has to use it all. Pick two different ways in which he could construct the garden.
Answer:
If the length is kept 16 or 14 and the breadth 8 or 10 the outer fencing can be 48 meters.
Step-by-step explanation:
The boundary gives the perimeter . Using the formula of the perimeter for a rectangle where L= length and B= breadth
P = 2(L+B)
48= 2(L+B)
24= (L+B)
The length must be longer than the breadth in the rectangle so we can obtain the sum of 24 in such a way that one side is longer than the other.
24= 16+8
or 24= 14+10
where the length can be 16 or 14 and breadth can be 8 or 10 .
If the length is kept 16 or 14 and the breadth 8 or 10 the outer fencing can be 48 meters.

Simplify the expression
Answer:
(3 x)/(5 x + 2)
Step-by-step explanation:
Simplify the following:
(3 x^2)/(5 x^2 + 2 x)
Hint: | Factor common terms out of 5 x^2 + 2 x.
Factor x out of 5 x^2 + 2 x:
(3 x^2)/(x (5 x + 2))
Hint: | For all exponents, a^n a^m = a^(n + m). Apply this to (3 x^2)/(x (5 x + 2)).
Combine powers. (3 x^2)/(x (5 x + 2)) = (3 x^(2 - 1))/(5 x + 2):
(3 x^(2 - 1))/(5 x + 2)
Hint: | Evaluate 2 - 1.
2 - 1 = 1:
Answer: (3 x)/(5 x + 2)
Answer:
The answer is [tex]\frac{3x}{5x+2}[/tex]
Step-by-step explanation:

Answer: the last one
Step-by-step explanation: B REPRESENTS
-2 ½ . POINT D REPRESENTS 1 ¾ .
1 ¾ is bigger than -2 ½
The answer choice that has the statement that is true about the number line can be seen in the first option.
What is a number line?A number line is a pictorial representation of lines on a calibrated straight line that serves as a basis for expressing real numbers on a straight line.
We should equally note that:
The left-hand side is the negative x-axis and,The right-hand side is the positive x-axis.From the given figures;
Point A lies to the negative axis direction on point scale 4 i.e -4Point D lies extremely to another point scale so we can say it is [tex]\mathbf{1 \dfrac{3}{4}}[/tex]Since 3/4 is roughly 0.75 = 1 + 0.75 = 1.75Therefore, we can conclude that Point A represents -4, Point D represents [tex]\mathbf{1 \dfrac{3}{4}}[/tex] and [tex]\mathbf{1 \dfrac{3}{4}}[/tex] > -4.
