how to solve this problem by finding x
Answer:
X=140
Step-by-step explanation:
Firstly, any Quadrilateral has a total sum of its angle equal to 360 degrees
The attachment you are showing us shows that we already know two angles
(70)&(60) degrees. I am assuming the line DC is a tangent, so angle ADC must be 90 degrees since a full angle on a tangent is equal to 180 degrees and there is 90 from the other side (180-90=90). Now we know 3 angles and what you have to do is find X so that when you add them all up they make a sum of 360.
X+70+60+90=360
X=360-70-60-90
X=140

Mike went to the store to buy shirts. The shirts were $45 each. The store was offering the following discount Mike decided to buy 3 shirts. Not including sales tax, how much money did Mike save by buying the shirts at the discounted price?
Answer:
54
Step-by-step explanation:
Mike saves $36 by buying the shirts at a discounted price.
What is the percentage?The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
Given the offer,
By 1 at regular price ($45) and get 40% off on two shirt
40 % of 45 ⇒ 0.40 × 45 = $18
So shirt price = 45 - 18 = $27/each
Since 2 shirt buy at this price = 2 × 27 = $54
Money saved = 2×45 - 54 = $36
Hence "Mike saves $36 by buying the shirts at a discounted price".

If there are 52 calories in one chicken nugget and 39 calories in one waffle fry, write an expression to represent the total number of calories consumed if you eat c chicken nuggets and w waffle fries. Next, find out total number of calories consumed if you ate 5 chicken nuggets and 10 waffle fries.
Multiply calories per nugget by number of nuggets and add to calories per waffle multiplied by number of waffles:
Total calories = 52c + 39w
Now replace the variables with the quantities and find total calories:
Total = 52(5) + 39(10)
Total = 260 + 390
Total = 650 calories

Which rational exponent represents a square root?
A. 1 / 2
B. 3/2
C. 1/3
D. 1/4
Answer:
1/2 rational exponent represents a square root.
Therefore, option A is correct.
Step-by-step explanation:
As we know that raising to the one-half power i.e. [tex]\frac{1}{2}[/tex] is the same
as taking the square root.
so [tex]x^{\frac{1}{2}}[/tex] is the same as the square root of [tex]x[/tex].For example, taking the square root of 4 will determine:
[tex]4^{\frac{1}{2}}[/tex]
[tex]\mathrm{Factor\:the\:number:\:}\:4=2^2[/tex]
[tex]4^{\frac{1}{2}}=\left(2^2\right)^{\frac{1}{2}}[/tex]
[tex]\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc},\:\quad \:a\ge 0[/tex]
[tex]\left(2^2\right)^{\frac{1}{2}}=2^{2\cdot \frac{1}{2}}[/tex]
so the expression becomes
[tex]4^{\frac{1}{2}}=2^{2\cdot \:\frac{1}{2}}[/tex]
[tex]=2^1[/tex]
[tex]=2[/tex] ∵ [tex]\mathrm{Apply\:exponent\:rule}:\quad \:a^1=a[/tex]
so, 1/2 rational exponent represents a square root.
Therefore, option A is correct.

Step-by-step explanation:
. If y varies directly with x when y = -4 and x = 10, determine y when x = 2. Write and equation for the direct variation and determine the value.
Answer:
y = - 0.8
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition when y = - 4, x = 10, then
- 4 = 10k ( divide both sides by 10 )
- 0.4 = k
y = - 0.4x ← equation of variation
When x = 2 , then
y = - 0.4 × 2 = - 0.8

HELP PLEASE!!
“I think of a number, double it, and add twelve. My answer is 54.” What number am I thinking of?
Answer:
21
Step-by-step explanation:
21 + 21 = 42
42 + 12 = 54
so 21 is your answer
Answer:
21.
Step-by-step explanation:
For questions like this, it's easiest to work your way backwards from the answer to get the original number.
In this case, you subtract 12 from 54, which gives you 42 (54-12=41)
Then, you divide by 2, the opposite of "doubling". 42 ÷ 2 = 21.
Since there are no other operations, your original number is 21.
To confirm, just go through the problem again starting with 21 and seeing if you get to 54.
21, doubled (42), add 12 = 54.
Which of the following statements is INCORRECT?
A. FE = 58
B. DE = 58
C. x = 8
D. DF = 40
Given:
In figure, ΔDEF has two equal angles ∠E and ∠F.
[tex]DE=40,EF=6x+10,DF=8x-24[/tex]
To find:
The incorrect statement from the given options.
Solution:
In triangle DEF,
[tex]\angle E=\angle F[/tex] (Given)
[tex]DF=DE[/tex] (Base angles are equal, so it is an isosceles triangle)
[tex]8x-24=40[/tex]
[tex]8x=40+24[/tex]
[tex]8x=64[/tex]
Divide both sides by 8.
[tex]x=8[/tex]
Now,
[tex]DE=DF=40[/tex] (Isosceles triangle)
[tex]EF=6x+10[/tex]
[tex]EF=6(8)+10[/tex]
[tex]EF=48+10[/tex]
[tex]EF=58[/tex]
Therefore, x=8, FE=58, DE =40 and DF = 40.
Hence, the incorrect statement is in option B. So, option B is correct.
An isosceles triangle has two equal opposites sides
The correct statements are
A. FE = 58
A. FE = 58C. x = 8
A. FE = 58C. x = 8D. DF = 40
incorrect statement is
B. DE = 58
Given:
Side DE = 40
Side FE = 6x + 10
Side DF = 8x - 24
Recall,
DF = DE
8x - 24 = 40
8x = 40 + 24
8x = 64
x = 64 / 8
x = 8
Therefore,
Side FE = 6x + 10
= 6(8) + 10
= 48 + 10
= 58
Side DF = 8x - 24
= 8(8) - 24
= 64 - 24
= 40

Please help will give BRAINLIEST
Answer:
D
Step-by-step explanation:
We have the equation:
[tex]x^2+y^2+12x-10y-7=0[/tex]
And we would like to convert this to an equation for a circle.
This will require completing the square. Thus, let’s factor group our factors. We will also move the constant to the right. Therefore:
[tex](x^2+12x)+(y^2-10y)=7[/tex]
To complete the square, we divide the b term by 2, square it, and then add the resulting constant to both sides.
Therefore, for the first term, we will have 12/2. 12/2 is 6. 6 squared is 36.
Hence, we would add 36 to both sides.
For the second term, we have -10/2. -10/2 is 5. 5 squared is 25. Hence, we would add 25 to both sides.
This yields:
[tex](x^2+12x+36)+(y^2-10y+25)=7+36+25[/tex]
We can now factor the two terms using the perfect square trinomial pattern. We will also add on the right. Hence, our equation is:
[tex](x+6)^2+(y-5)^2=68[/tex]
Therefore, our answer is D.

Given the diagram below. If G is the circumcenter of ABC. DC = 16, GB = 21 and AZ = 19, find each measure.
Answer:
Step-by-step explanation:
Properties of a circumcenter;
1). Circumcenter of a triangle is a point which is equidistant from all vertices.
2). Point where perpendicular bisectors of the sides of a triangle meet is called circumcenter of the triangle.
From the picture attached,
9). AG = GB = GC = 21
10). BC = 2(DC)
= 2×16
= 32
11). By applying Pythagoras Theorem in ΔGFB,
GB² = GF² + FB²
(21)² = GF² + (19)²
441 = GF² + 361
GF² = 441 - 361
GF = [tex]\sqrt{80}[/tex]
GF = 8.9
12). By applying Pythagoras theorem in ΔGDB,
GB² = DG² + BD²
(21)² = (DG)² + (16)² [BD = DC = 16]
DG² = 441 - 256
DG = √185
DG = 13.6

Answer:
The possible lengths of TR : TR = 17, 40, 42, 52,
Step-by-step explanation:
Given: Triangle WTR with WT = 25 and WR = 40. Identify all possible lengths for TR.
To find the possible lengths of the third side of a triangle:
c - a< b > a + c
a = WT = 25
c = WR= 40
b = TR = ??
40 - 25 < b < 40 + 25
15 < b < 65
The possible lengths of TR has to be greater than 15 and less than 65, Hence: TR = 17, 40, 42, 52,
