6. Pop's Cycle Shop sells bicycles and tricycles. The number of bicycles is 1 less than 5 times the number
of tricycles. All the bicycles and tricycles together have a total of 154 wheels. Find how many bicycles
and tricycles are there.
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Linear equations.
Let the number of bicycles = x
and number of tricycles = y
the relationship given is,
x = 5y-1
number of wheels of bicycle = 2x and of tricycles=3y
and other relation is, 2x+3y = 154
so now substituting we get as,
==> 2(5y-1) +3y= 154
10y-2+3y = 154
13y = 154+2
=> y = 12
=> 12*3 = 36 wheels of tricycles
so, 154-36 => 118 wheels of the bicycle.
so the number of bicycles = 118/2 = 59
hence,
==> number of bicycles = 59 and tricycles = 12

Answer:
M=x/7 let's say M is what Micheal earned, and so he earns x dollars every seven days
L=2(M)
L=2(x/7)Let's say L is what Lee earned, she earned twice as much as Micheal so 2(x/7)
Total=2(x/7)+x/7
Total=3(x/7) the total earnings is the sum of x/7 and 2x/7 is 3x/7

an isosceles triangle is drawn with base angles 24 degrees and a base of 28 cm. Find the base angles of the isosceles triangle with the same base but with treble the area.
Answer:
Step-by-step explanation:
height = 14tan(24°)
area = 0.5(base)(height)
Find the angle that triples the height.
tanθ = 3×14tan(24°)
θ = arctan(3×14tan(24°)) ≅ 53.2°
The base angle will be 53.3 degrees when the area gets treble.
What is isosceles triangle?A triangle with two sides of equal length is an isosceles triangle.
What are base angles?The angles that have the base as one of their sides are called base angles.
Formula for area of triangle[tex]Area = \frac{1}{2} bh[/tex]
Where,
b is the base of the triangle
h is the height of the triangle
According to the given question
We have,
Base angle of the isosceles triangle is 24 degrees.
Base of the isosceles triangle is 28 cm.
In triangle ABC
We have
BC = 28cm, BD = 14cm, AD = h and ∠ABD = 24 degrees
Now, in right angle triangle ABD
[tex]tan24 = \frac{h}{14}[/tex]
⇒ tan24 × 14 = h
Therefore,
Area of triangle ABC = [tex]\frac{1}{2}[/tex] × 28 × 14 × tan 24
Area of triangle ABC = 196tan24
Therefore, the base angles of an new isosceles triangle when the area get treble is given but with the same base by
Area of new isosceles = 3× area of triangle ABC
⇒ [tex]\frac{1}{2}[/tex]× 28 × tanθ × 14 = 3×196tan24
⇒tanθ = 3 × 0.4452
⇒ tanθ = 1.3356
⇒ θ = [tex]tan^{-1}(1.34)[/tex]
⇒ θ = 53.3 degrees
Hence, the base angle will be 53.3 degrees when the area gets treble.

If NQZ ~ CBK, find BK
Answer:
65
Step-by-step explanation:
if they are similar their sides are in proportion and so are the corresponding medians
to see their corresponding sides line up the names of the triangles
N Q Z
⇵⇵⇵
C B K
BK / QZ = 45/27 ; substitute whit what you see in the picture
(4x+1) / (2x+7) = 45/27 ; cross multiply
27( 4x+1) = 45( 2x+7) ; distribute
108x + 27 = 90 x + 315; subtract 90x and 27 from both sides
108x -90x = 315 -27; combine like terms
18x = 288; divide both sides by 18
x=16
BK = 4* 16 +1 = 65
bob wants to build a doghouse that is 2 feet longer than it is wide. he's building it on a concrete slab that will leave 2 feet of concrete slab visible on each side. if the area of the doghouse is 48 square feet, what are the dimensions of the concrete slab
Answer:
10 ft by 12 ft
Step-by-step explanation:
This problem requires you to first write an equation to represent the situation. Here we will represent the shorter side of the doghouse with the variable x, the longer side will be represented with x+2 because it is 2 feet longer.
48 = x * (x+2)
This represents the area of the doghouse as the product of the width and length of the doghouse.
48 = x^2 + 2x
Now, we need to move all the items onto one side of the equals sign, it is best to have the x^2 be positive.
0 = x^2 + 2x - 48
Now, we factor to find what x equals.
0 = (x-6) * (x+8)
From here, we can use each of the terms in parentheses to solve for x.
0 = x-6
x = 6
0 = x+8
0 = -8
Here we know that the shorter side has to be 6 ft because length is a positive number, and we can determine that the longer side is 8 ft because it is 2 ft longer. The dimensions of the slab are therefore 10 ft by 12 ft because the slab is 2 ft on each side, therefore adding an extra 4ft to the dimensions because the 2ft is added on each side.

The value of the account increases at a constant percent rate per year.
Answer:
false
true
false
Step-by-step explanation:
If an account earns a fixed rate of interest compounded quarterly, the value of the account increases every quarter.

If an account earns an interest that is compounded yearly, the value of the account increases at a constant percent rate per year
A study of immunizations among school-age children in California found that some areas had rates of unvaccinated school-age children as high as 13.5%. Imagine a district in the state where 13.5% of children are unvaccinated. If three children are chosen randomly (assume they are not siblings) from this district, what is the probability that all three children have been vaccinated
Answer: 0.6472
Step-by-step explanation:
Given: The proportion of unvaccinated school-age children = 13.5%
Then, the proportion of vaccinated school-age children :p=100%-13.5%
= 86.5% = 0.865
Total children selected :n=3
Binomial probability formula:
[tex]P(X=x)=\ ^nC_xp^x(1-p)^{n-x}[/tex]
The probability that all three children have been vaccinated :
[tex]P(X=3)=\ ^3C_3(0.865)^3(0.135)^0\\=(1)(0.647214625)\approx0.6472[/tex]
Hence, the required probability = 0.6472
