Answer:
1/2x
Step-by-step explanation:
Dennis read 30% of his book on Tuesday and 1/5 of his book on Wednesday. If he started the book on Tuesday, what fractional part of the book did he have left to read after Wednesday?
Total pages of the book = x
Tuesday = 30%
= (30/100)x
= 3/10x
Wednesday = 1/5x
3/10x + 1/5x
= 3x+2x/10
= 5/10x
= 1/2x
what fractional part of the book did he have left to read after Wednesday
= x - 1/2x
= 2x-x/2
= x/2
= 1/2x
Are adjacent angles ever congruent?
Select the reason why these triangles are
similar. If they are not, select "Not similar".
A. AA
B. SAS
C. SSS
D. Not similar
Answer:
B. SAS
Step-by-step explanation:
In the given diagram, it would be observed that each side of the bigger triangle are multiplied by a factor of [tex]\frac{1}{3}[/tex] to give the values of each corresponding sides of the smaller triangle. But the included angle of the two triangles are the same.
Therefore, the reason why the triangles are similar is because of side-angle-side (SAS) relations. The correct option is B.
Answer:
SAS

Answer:
9.0, 9.012, 9.201, 9.210
Step-by-step explanation:
9.0 has no decimal numbers, so it goes at the beginning, 9.012 is the next greatest, then 9.201, and finally, 9.21. Also, a zero at the end of a decimal number adds nothing.

The video streaming service that you want to use is represented with the equation
below, where y represents the the total monthly cost of the service and x represents
the number of videos you plan to stream each month:
y = $1.25x + $5.00
Create a table for the values when x = 0, 5, 8, 10, 30
x-value
y-value
0
5
8
10
30
Answer:
HERES THE ANSWER
Step-by-step explanation:
0 = 5.00
5 = 11.25
8 = 15.00
10 = 17.50
30 = 42.50
also to understand it easier. # 1.25 times (whatever number), then take whatever that equals and add it to 5.00 ! (works for any question, just substitute the numbers)
To create a table for the values when x is given value, you can put those value in given function and can calculate what does y evaluates to.
The corresponding values of y are:
[tex]\begin{array}{cc}x&y\text{(In dollars)}\\0&5\\5&11.25\\8&15\\10&17.5\\30&42.5\end{array}\right[/tex]
Given that:y represents the total monthly cost to the servicex represents the number of videos you plan to stream each month. y = $1.25x + $5.00 ( a linear function )To find:Values of y for values of x as x = 0, 5, 8, 10, 30
Using the relation between y and x to find the values of y to corresponding values of x:For x = 0:[tex]y = 1.25x + 5\\ \\ y = 1.25x + 5|_{x=0}\\ y = 1.25 \times 0 + 5\\ y = \$5\\ \\ [/tex]
For x = 5:[tex]y = 1.25x + 5\\ \\ y = 1.25x + 5|_{x=5}\\ y = 1.25 \times 5 + 5\\ y = \$11.25\\ \\ [/tex]
For x = 8:[tex]y = 1.25x + 5\\ \\ y = 1.25x + 5|_{x=8}\\ y = 1.25 \times 8 + 5\\ y = \$15\\ \\ [/tex]
For x = 10:[tex]y = 1.25x + 5\\ \\ y = 1.25x + 5|_{x=10}\\ y = 1.25 \times 10 + 5\\ y = \$17.5\\ \\ [/tex]
For x = 30:[tex]y = 1.25x + 5\\ \\ y = 1.25x + 5|_{x=30}\\ y = 1.25 \times 30 + 5\\ y = \$42.5\\ \\ [/tex]
Thus, the corresponding values are:
[tex]\begin{array}{cc}x&y\text{(In dollars)}\\0&5\\5&11.25\\8&15\\10&17.5\\30&42.5\end{array}\right[/tex]

i’ll give u brainliest!! what is the shape of 1, 2 and 3
Answer:

2.96.04
3.110.41
Step-by-step explanation:
Answer:
Shape 1: 96.04
Shape 2: 110.41
Shape 3: 75.43
Step-by-step explanation:
For shape 1, you can do 9.8*9.8 and get the answer of 96.04. For shape 2, you can do 6.1*18.1 to get the answer of 110.41. Finally for shape 3, you can find the whole circle and divide it by 4 because it is only a quarter of the circle. The radius being 9.8, you then get the area of 301.72. But since its only a quarter of a circle you divide by 4 and get 75.43.

What angle relationship describes ∠UQR and ∠WRT? segments UV and WZ are parallel with line ST intersecting both at points Q and R respectively Alternate interior angles Alternate exterior angles Corresponding angles Vertical angles
Answer:
Corresponding Angles
Step-by-step explanation:
I got it right on the test ;)
GOOD LUCK!
The angle ∠UQR and angle ∠WRT are the corresponding angles. Then the correct option is C.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Corresponding angle - If two lines are parallel then the third line. The corresponding angles are equal angles.
The segments UV and WZ are parallel with line ST intersecting both at points Q and R respectively.
Then the angle ∠UQR and angle ∠WRT are the corresponding angles.
Then the angle ∠UQR and angle ∠WRT are congruent to each other.
∠UQR = ∠WRT (corresponding angle)
Then the correct option is C.

1. What is the area of a circle with a a diameter of 20 cm in terms of pi?
2. What is the area of a circle with a radius of a 8 yd using 3.14 as pi?
3. The area of a circle in terms of pi is 49pi. What is the radius of the circle?
Help needed and it would be appreciated
Answer:
1. 100pi cm
2. 200.96 yd
3. 7
Step-by-step explanation:
1.) diameter = radius multiple by two (D = r × 2)
&
radius = diameter divided by two (r = D ÷ 2)
So
20 ÷ 2 = 10 => A = pi (10)power 2 => A = 100pi
---------------------------------------------------------------------------------------------
2.) 3.14 × (8)power2 =200.96
---------------------------------------------------------------------------------------------
3.) A = 49pi => 49pi = pi(r)power2
[ cross out the pi from both sides]
And your left with
49 = (r)power2
[square root both sides to get rid of the power]
And your left with
7 = r

Step-by-step explanation:
[tex]36x^3 + 27x^2 = 0[/tex]
Take 9x² common from the expression on L.H.S.[tex]=> 9x^2(4x + 3) = 0[/tex]
Here, x will have 2 values :-
1) [tex]9x^2(4x + 3) = 0[/tex]
Divide both the sides by (4x + 3)[tex]=> \frac{9x^2(4x + 3)}{(4x+3)} = \frac{0}{4x+3}[/tex]
[tex]=> 9x^2 = 0[/tex]
Divide both the sides by 9x[tex]=> \frac{9x^2}{9x} = \frac{0}{9x}[/tex]
[tex]=> x = 0[/tex]
2) [tex]9x^2(4x + 3) = 0[/tex]
Divide both the sides by 9x²[tex]=> \frac{9x^2(4x + 3)}{9x^2} = \frac{0}{9x^2}[/tex]
[tex]=> 4x+3 = 0[/tex]
Substract both the sides from 3[tex]=> 4x+3 -3 = 0 - 3[/tex]
[tex]=> 4x=-3[/tex]
Divide both the sides by 4[tex]=> \frac{4x}{4} = \frac{-3}{4}[/tex]
[tex]=> x = -\frac{3}{4}[/tex]
