Answer:
140°
Step-by-step explanation:
oh, come on, this is like "you have 8 apples as a mixture of red and green apples. 5 apples are red, how many are green ?".
it is the same here.
the total angle is 170°.
now we know a part of it is 30°.
how large is the rest ?
well, it is 170 - 30 = 140°

Help!A 2-column table with 5 rows. Column 1 is labeled Type of flower with entries lilies, daisies, carnations, asters, daffodils. Column 2 is labeled Amount with entries 60, 36, 72, 42, 24.
The florist makes the greatest number of identical arrangements with the lilies and the daisies. Which combination describes the arrangements?
A.6 arrangements with 10 lilies and 6 daisies
B.6 arrangements with 6 lilies and 10 daisies
C.12 arrangements with 10 lilies and 6 daisies
D.12 arrangements with 5 lilies and 3 daisies
The greatest number of identical arrangements the florist can make is .12 arrangements with 5 lilies and 3 daisies.
What is the greatest number of identical arrangements?The greatest number of identical arrangements with the lilies and the daisies the florist can make would be equivalent to the highest common factor of the number of lilies and daisies.
The highest common factor of two or more numbers is the highest number that can divide the numbers evenly without leaving any remainder. For example, the highest common factor of 4 and 8 is 4.
Factors of 60= 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60.
Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18, and 36.
Common factors = 1, 2, 3, 4, 6, 12
Highest common factor = 12
Number of daisies = 36 /12 = 3
Number of lilies = 60 / 12 = 5

A pre-image includes a line segment with the length of z units in a slope of M units the pre-image is dilated by a scale factor of N. The length of a corresponding line segment in the image is blank units
The length of a corresponding line segment in the image is; Nz
How to find the Slope of the Line Segment?We know that;
Slope is the ratio of change in y-value and change in x-value.
Thus, dilation does not change the slope of any line.
Now, after dilation; M---->M
Length of line:
We know that a dilation has the effect of stretching or shrinking the line segment by the factor of N units
We are given
Length of line = z
Thus, the length after dilation will become

Demuestra los valores de las funciones trigonométricas del ángulo de 0°
The values of the trigonometric functions of the 0° angle are, cos 0° = 1, sin 0° = 0 ,tan 0° = 0, cot 0° = ∞, sec 0° = 1 , cosec 0° = ∞.
What is trigonometric functions?The simplest definition of a trigonometric function is the function of an angle in a triangle, also known as a circular function. It implies that these trigonometric functions can be used to determine the relationship between a triangle's angles and sides. The fundamental trigonometric operations include sine, cosine, tangent, cotangent, secant, and cosecant.
Now given degree is 0 ,
So, we know that sin 0° = 0,
And cos 0° = 1,
⇒tanθ=sinθ/cosθ,
Here θ = 0°
⇒tan 0° = 0/1,
⇒tan 0° = 0,
Now as cot θ is the inverse of tan θ, we get,
⇒cot θ = 1/tan θ,
⇒cot 0°= 1/0,
⇒cot 0° = ∞,
Now we know that cosec θ is the inverse of sin θ, we get,
⇒cosec θ = 1/sin θ,
⇒cosec 0° = 1/0,
⇒cosec 0° = ∞
And we know that sec θ is the inverse of cos θ we get,
⇒sec θ = 1/cos θ,
⇒sec 0° = 1/1,
⇒sec 0° = 1.

Johnny opened a savings account and deposited $95, and then saved $15 per week. Write an equation representing this scenario. Use for her bank account balance and for the number of weeks that have passed since opening her account.
The following linear equation gives Johnny's savings w weeks after her opened the account.
S(w) = $95 + $15*w
Which equation shows Johnny savings?We know that initially, Johnny deposits an amount of $95, and then he saves $15 per week.
So, after w weeks, the amount in that savings account will be:
S(w) = $95 + $15*w

The measures of the unknown angles are as follows:
∠DEA = ∠BEC = 60°∠AEB = ∠CED = 120°How to find the measure of angles?The measures of each angles can be found as follows:
Therefore,
∠AEB = ∠CED (vertically opposite angle)
∠DEA = ∠BEC (vertically opposite angle)
Vertically opposite angles are equal.
Therefore,
4x = 75 - x
4x + x = 75
5x = 75
x = 75 / 5
x = 15
Therefore,
∠DEA = ∠BEC = 4(15) = 60°

8 cm
Work out the area of the triangle.
Optional working
5.2 cm
Answer:
cm²
Answer:
20.8 cm^2.
Step-by-step explanation:
Area = 1/2 * base * height
= 1/2 * 8 * 5.2
Answer:
A = 20.8 cm²
Step-by-step explanation:
We have just to use the following expression:
A = (Base x height) / 2
So:
A = (8 x 5.2) / 2
A = 4 x 5,2
A = 20.8 cm²

Answer:
Step-by-step explanation:
I guess you want to draw the graph.
The graph is a straight line
-6x - 20 = 4y
When x = 0:
-6(0) - 20 = 4y
y = -20/4 = -5
So, one point on the graph
= (0, -5)
When y = -2:
Plugging y = -2 into the equation:
-6x - 20 = 4(-2)
-6x = -8 + 20 = -12
x = -2
So, another point is (-2, -2)
Mark these 2 points on the graph paper

A certain plant grows 1 1/6 inches each week. it will rake the plant to grow 6 1/6 inches is 5 weeks 2 days.
What is the definition of time?Time is ongoing progression of existence and things that happen in what seems to be an irrevocable order from the past, present, and forward into the future. It is a quantity that is part of several measurements that are used to compare the length of events or the gaps between them, to compare how long they last, to order events, and to measure how quickly the things change in the real world or in our conscious experience. Along with the three spatial dimensions, time is frequently referred to as a fourth dimension.
Time has long been an important subject of study in religion, philosophy, and science, but defining it in a manner applicable to all fields without the circularity has consistently eluded scholars. Nevertheless, diverse fields such as the business, industry, sports, sciences, and the performing arts all incorporate some notion of time into their respective measuring systems.
A certain plant grows every week = [tex]1\frac{1}{6}[/tex] = [tex]\frac{7}{6}[/tex] inches
1 week = 7 days
Therefore in 1 day plant grows = [tex]\frac{\frac{7}{6} }{7}[/tex]
= [tex]\frac{1}{6}[/tex] inch
Now we have to calculate the number of days in which the plant grows [tex]6\frac{1}{6}[/tex] inches ≈ [tex]\frac{37}{6}[/tex] inch
Number of days = [tex]\frac{Total growth}{growth in one day}[/tex]
