Answer:
A lily costs $7 and a geranium $4.
Step-by-step explanation:
From the question we can write two equations. let the number of lilies be l and the number of geraniums be g, then:
5
g
+
4
l
=
48
4
g
+
6
l
=
58
Multiply the first equation by 4 and the second by 5, the number of lilies in the other, gives:
20
g
+
16
l
=
192
20
g
+
30
l
=
290
Subtract the first equation from the second gives:
14
l
=
98
which dividing by 14 gives
l
=
7
Substituting the value
l
=
7
in the first equation gives:
5
g
+
28
=
48
Subtract 20 from both side gives:
5
g
=
20
divide by 5 gives
g
=
4
So, a lily costs $7 and a geranium costs $4.
Answer:A lily costs $7 and a geranium $4.
Step-by-step explanation:From the question we can write two equations. let the number of lilies be L and the number of geraniums be g, then:
5g+41=48
4g+6 L=58
Multiply the first equation by 4 and the second by 5, the number of lilies in the other, gives:
20g + 16 L=192
20g + 30 L=290
Subtract the first equation from the second gives:
14 L =98 which dividing by 14 gives L=7
Substituting the value L = 7
in the first equation gives:
5g + 28 = 48
Subtract 20 from both side gives:
5g = 20
divide by 5 gives
g = 4
So, a lily costs $7 and a geranium costs $4.

State if the triangles in each pair are similar. If so, state how you know they are similar.
Answer:
A) similar; SAS similarity.
Step-by-step explanation:
SAS Triangle Similarity
The SAS criterion for triangle similarity states that if two sides of one triangle are proportional to two sides of another triangle and their included angles are congruent, then the triangles are similar.
We are given two triangles BCD and JKL. Sides DB and JL have a ratio of 90/20 = 4.5
Sides JK and BC have a ratio of 81/18 = 4.5
Since both sides are proportional and their included angle of 43° are congruent, then both triangles are similar, SAS similarity.
A) similar; SAS similarity.
Michael pays $30 to enter a state fair, plus $4 for each ride. Which of the following
equations represents his total cost?
A. y = 30x + 4
B. y = 34x
C. y = 4x + 30
D. y = 4x + 34
PLEASE HELPP!!!
Answer:
The required equation is:
[tex]y=4x+30[/tex]
So, Option C is correct option.
Step-by-step explanation:
Entry fee for fair = $30
Cost of one ride = $4
Cost of x rides = $4x
If y represents the total cost the equation will be sum, of entree fee and cost of x rides i.e
[tex]y=4x+30[/tex]
The required equation is:
[tex]y=4x+30[/tex]
So, Option C is correct option.
There are 35 female performers in a dance recital. The ratio of men to women in the recital is 2 : 7 How many men are in the recital?
There are 32 female performers in a dance recital the ratio of men to women is 3/8 How many men are in the dance recital
But we have 32 female performers in the dance recital. Hence there are 3×4=12 men in the dance recital.
If cosθ=3/5, find tanθ
Answer and step-by-step explanation:
cos = adj/hyp (in a right triangle)
cos0 = 3/5
adj = 3
hyp = 5
opp = sqrt( 5^2 - 3^2) = sqrt( 25-9) = sqrt(16) = 4 (Pythogorean theorem)
tan0 = opp/adj = 4/3
Answer:
[tex]\boxed {\boxed {\sf tan( \theta)=4/3}}[/tex]
Step-by-step explanation:
Cosine is equal to adjacent over hypotenuse.
cos(x)=adjacent/hypotenuseWe are given: cosθ=3/5
Therefore, the adjacent is 3 and the hypotenuse is 5.We want to find tanθ. Tangent is equal to opposite over adjacent.
We need to find the other leg of the triangle, which is the "opposite". Use Pythagorean Theorem.
[tex]a^2+b^2=c^2[/tex]
The hypotenuse (c) is 5.
[tex]a^2+b^2=5^2[/tex]
One leg (a) is 3, the other (b) is unknown.
[tex]3^2+b^2=5^2[/tex]
Evaluate all the exponents.
[tex]9+b^2=25[/tex]
Subtract 9 from both sides of the equation.
[tex]9-9+b^2=25-9[/tex]
[tex]b^2=16[/tex]
Take the square root of both sides.
[tex]\sqrt{b^2} =\sqrt{16}[/tex]
[tex]b=4[/tex]
Now we know the "opposite" is 4. We can find the tangent now.
[tex]tan(x)=opposite/adjacent[/tex] (opposite=4, adjacent=3)
[tex]tan( \theta)=4/3[/tex]
The tangent of theta is 4/3

14.) Mr. Lovell was playing cards with his son. In the first round he earned 52
points. In the second round he lost 20 points. How would you write this as
an addition problem?
Answer:
That would be;
+52-20
Step-by-step explanation:
From the first part, he gained/earned 52 points
This is a positive so we have + 52
In the second round , he lost 20
This is a negative so we have - 20
Writing this as an addition problem, it will be;
+52-20

If one side of a square is represented by x + 7, and the perimeter of the square is
represented by 8x - 20, what is the value of X?
Solve for x pls help i don’t wanna fail :) if u don’t that’s fine
[tex]\huge\frak{Answer:-}[/tex]
[tex](8x - 8) + {100}^{\degree} = {180}^{\degree} [/tex]
[tex]\implies8x - 8 = 180 - 100[/tex]
[tex]\implies8x - 8 = 80[/tex]
[tex]\implies8x = 80 + 8[/tex]
[tex]\implies8x = 88[/tex]
[tex]\implies x = \frac{88}{8} [/tex]
[tex]\implies x = 11 \: (a)[/tex]
Why did we used the equation "(8x - 8) + 100° = 180°" to find x?
Because, sum of interior angle in the same side of two parallel lines are always equal to 180°.
Don't forget to give the "°" symbol ;)

8 + 3x - 1 + 9 = 28 (collect like terms)
3x + 16 = 28 (subtract 16 on both sides)
3x = 12 (divide by 3 on both sides)
x = 4
QR + RS = QS
(PLUG IN)
3(4) - 1 + 9 = QS (distribute)
12 - 1 + 9 = QS (collect like terms)
20 = QS

Every year on November 1, the Stablo family plants a tree. This tradition has
happened for generations and the first tree the family planted is now 183 years
old. Two of the trees were planted in their backyard; one is an apple tree and the
other is a maple tree. The maple tree is older than 100, but was not the first tree
planted. On November 1 of this year, the age of the maple tree is fifteen times
the age of the apple tree.
On November 1 of some year from now, the age of the maple tree will be eleven
times the age of the apple tree. How old are the trees that year?

The sum of the ages of David and Morgan is 78 years. 7 years ago, David's age was 3 times Morgan's age. How old is David now?
Answer:
David is 55 years old
Morgan is 23 years old
__________________________________________________________
Step-by-step explanation:
Let the age of David = x years
Let the age of Morgan = y years
We are Given:
The sum of David and Morgan's age is 78
7 years ago, David's age was 3 times Morgan's age
__________________________________________________________
Making the equations:
from the first statement, the sum of their ages is 78
So, we can write it as:
x + y = 78
from the second statement,7 years ago, David's age was 3 times Morgan's age
David's age 7 years ago = (x - 7)
Morgan's age 7 years ago = (y-7)
So, we can write the equation as:
(x - 7) = 3(y - 7)
which can be simplified to:
x = 3y - 14
__________________________________________________________
Solving the equations:
We have the 2 equations:
x + y = 78x = 3y - 14from the first equation, we can say that:
x = 78 - y
Using this value in the second equation:
x = 3y - 14
78 - y= 3y - 14 [since x = 78 - y]
78 + 14 = 4y
4y = 92
y = 23
Using this value in the first equation:
x + y = 78
x + 23 = 78 [since y = 23]
x = 55
__________________________________________________________
The Age of David and Morgan:
Since we assigned x to the age of David:
David is 55 years old
We assigned y to the age of Morgan. So,
Morgan is 23 years old
