Answer:
There are 20 students in the class
Step-by-step explanation:
Let the total number of children in the class be = x
from the question, we know that 20% of all the children are left-handed. We also know that 20% of the total children in the class = 4.
This means that 20% of x = 4
Wherever we see the word "of" in an arithmetic problem, we should know that it infers a multiplication there.
Hence, we have
[tex]\frac{20}{100} \times x = 4[/tex]
[tex]x = \frac{4 \times 100}{20}= 20[/tex]
There are 20 children in the class altogether

x = 36 ÷ 3
x = 12
12 + 24 = 36
Answer:
12
Step-by-step explanation:

Krystal and Danielle each improved their yards by planting daylilies and ivy. They bought their supplies from the same store. Krystal spent $114 on 1 daylily and 12 pots of ivy. Danielle spent $150 on 10 daylilies and 10 pots of ivy. Find the cost of each item.
Answer:
$9 and $6Step-by-step explanation:
Let the cost of daylilies = d and ivy = i, then we have below equations:
d + 12i = 11410d + 10i = 150Simplify the second equation:
d + i = 15Subtract the second equation from the first:
d - d + 12i - i = 114 - 1511i = 99i = 9, ivy costs $9Now find d:
d = 15 - 9 = 6, daylilies cost $6Help ASAP please help

Answer:
Use substitution method

8=8
Hope this helps. Have a nice day you amazing bean child.
-7 + 15 = 8
Move the 7 over to the 8, the negative sign becomes a positive.

any answers? im bit stuck on this
Step-by-step explanation:
The vertical angles are congruent. The right angles are congruent. There are 2 angles of a triangle congruent to 2 angles of anther triangle. By AA Similarity the triangles are similar.
Statement A. (vertical angles are congruent)
Statement D. (right angles are congruent)
Triangle AEC is similar to triangle BDC.
Statement E is true but does not help.
Correct statement of proportional side lengths:
BD/AE = CD/CE
x/150 = 200/50
x/150 = 4
x = 600
P.S. I think there is a mistake in the problem. I don't think that statement E is correct. It is a true statement, but it is useless. Statement F is false.

List two equivalent numbers to 0.50
1/5 - 1/6
Plz ans. Fasttt
Answer: 1/30
5 and 6 both have a common factor of 30
30 will be our ned denominator
1/5 needs to be multipliued by 6
(since 5 times 6 is 30)
and
1/6 needs top be multiplied by 5
(since 6 times 5 is 30)
then you get 6/30 - 5/30 and that is just 1/30

Answer:
1.81.34
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.

Put the following numbers in order from least to greatest. 9.201, 9.210, 9.012, 9.0
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.

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.

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]

Step-by-step explanation: apply exponent rule rewrite factor out common term plz enjoy
Answer:
[tex]x = 0\; ,-\frac{3}{4}[/tex]
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]
Write the equation of a line with a slope of 3 that passes through (-3,2).
Answer:
y = 3x + 11
Step-by-step explanation:
Substitute the information into the point-slope form equation.
Point-slope form: y - y₁ = m(x - x₁)
y - 2 = 3(x - (-3))
y - 2 = 3(x + 3)
y - 2 = 3x + 9
y = 3x + 11
