Oak Street and Elm Street run parallel to each other. When Main Street
intersects them, it forms interior 26, measuring 70°. What is the measure of
24?
Answer:
110°
Step-by-step explanation:
The consecutive interior angles theorem states that when two parallel lines are cut by a transversal, the pair of angles formed which lie inside the parallel lines on the same side of the transversal are known as consecutive interior angles. This consecutive interior angles are supplementary (that is add up to 180°).
Therefore:
∠4 and ∠6 are consecutive interior angles. Hence:
∠4 + ∠6 = 180° (sum of co-interior angles)
∠4 + 70 = 180
∠4 = 180 - 70
∠4 = 110°
Answer:
110°

two families go to the zoo
the smith family of two adults and three children pay £61
the jones family of three adults and five children pay £96
how much is one adult ticket and how much is one childrens ticket
Answer:
So adult tickets cost £17.00 and child tickets cost £9.00
Step-by-step explanation:
2a+3c=61
2a=61-3c
a=30.5-1.5c
...
3a+5c=96, using a found above we get:
3(30.5-1.5c)+5c=96
91.5-4.5c+5c=96
91.5+0.5c=96
0.5c=4.5
c=9, and since a=30.5-1.5c
a=17
So adult tickets cost £17.00 and child tickets cost £9.00
Answer:
The adult tickets cost £17.00 and child tickets cost £9.00
Step-by-step explanation:
2a + 3c = 61
2a = 61 - 3c
a = 30.5 - 1.5c
3(30.5 - 1.5c) + 5c = 96
91.5 - 4.5c + 5c = 96
91.5 + 0.5c = 96
0.5c = 4.5
c = 9
a = 30.5 - 1.5c
a = 17
The adult tickets cost £17.00 and child tickets cost £9.00

PB > 10) =
Answer: 0.6
Step-by-step explanation:
0.6 is the probability that Nuan scans greater than 10 barcodes before the scanner misreads one.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Given,
Nuan is using a faulty barcode scanner that misreads barcodes 5% of the time.
Let B = the number of barcodes Nuan scans until the scanner misreads one.
n=10
p=5%=0.05
Mean=1/p=1/1/20=20
Variance=1-p/p²
=1-1/20/(1/20)²
=19/20×400
=380
Standard deviation=√380=2√95=19.493
p(x=10)=0.0315
p(x<10)=0.3697
p(x≤10)=0.40126
p(x>10)=0.598
=0.6
Hence, 0.6 is the probability that Nuan scans greater than 10 barcodes before the scanner misreads one.

Write the equation of the line in fully simplified slope-intercept form.
Answer:
y = -x + 2
Step-by-step explanation:
[slope-intercept form] y = mx + b
m [slope] = ∆y/∆x = y₂–y₁ / x₂–x₁
b [y-intercept] = (0,b) → x = 0.
If y = 2 when x = 0, b = 2.
Since y decreases by 1 unit everytime x increases by 1 unit
a decrease by 1 unit is represented by -1, and an increase of 1 is represented by 1.
So a decrease of -1 over an increase of 1
is -1/1 = -1 = m.

Read the passage from an online source.
Aqueducts were amazing feats of engineering given the time period. Though earlier civilizations in Egypt and India also built aqueducts, the Romans improved on the structure and built an extensive and complex network across their territories. . . .
Aqueducts required a great deal of planning. They were made from a series of pipes, tunnels, canals, and bridges. Gravity and the natural slope of the land allowed aqueducts to channel water from a freshwater source, such as a lake or spring, to a city.
–"Roman Aqueducts,”
National Geographic

What is the equation of the line that passes through the point (-3, 1) and
has a slope of 4/3?
y = 4/3x +5 is the equation of the line that passes through the point (-3, 1) and has a slope of 4/3.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
Let us use point-slope formula y-y₁ = m(x-x₁) with point (-3,1) and slope m of 4/3.
Plug in the values
y-1 =4/3(x-(-3))
y-1 = 4/3(x+3)
Apply distributive property
y-1 =4/3x +4
Add 1 on both sides
y = 4/3x +5
Hence, y = 4/3x +5 is the equation of the line that passes through the point (-3, 1) and has a slope of 4/3.

A sign says that the price marked on all music equipment is 30% off the original price. You buy an electric guitar for the sale price of $315.
What is the original price?
Answer:
The original price is $409.5
Step-by-step explanation:
the 2 numbers that you have in this equation are 315 and 30% (or .30)
You want to multiply 315 by .3 to get an answer of 94.5
That's the amount of money that was marked down on the guitar
So you want to add 94.5 to 315 which gives you 409.5

Which proportion must be true?
*answers are in the picture*
Answer:
St/EF = WR/CD
Step-by-step explanation:
The ratio of corresponding sides is same for all the sides for similar polygon. the correct proportion is,
[tex]\dfrac{ST}{EF} =\dfrac{WR}{CD}[/tex]
Thus the option H is the correct option.
To find the correct proportion we need to know about the properties of slimier polygon.
What are the properties of similar polygon?Two polygons are said to be similar or congruent pentagon-
The corresponding angle of two pentagons are congruent.
The ratio of corresponding sides is same for all the sides.
The figure given in the problem of similar two polygons with six sides.
Rearrange the second figure as shown in figure.
As for the similar polygons, the ratio of corresponding sides is same for all the sides.
Thus the sides shown in the two rearranged figure must be same. Therefore,
[tex]\dfrac{ST}{EF} =\dfrac{WR}{CD}[/tex]
Hence the correct proportion is,
[tex]\dfrac{ST}{EF} =\dfrac{WR}{CD}[/tex]
Thus the option H is the correct option.

Ms. Fords kitchen is in the shape of a rectangle with a width of 12.25 feet she is buying a wallpaper border to go on all of the kitchen walls she wants to buy 5 extra feet of the border to make sure she has enough she buys 62.5 feet of the border what's the length of her kitchen?
Answer:
Length of the rectangle = 16.5 feet
Step-by-step explanation:
Border length bought = 62.5 feet
Including 5 feet extra
Border length needed = 62.5 feet - 5 feet
= 57.5 feet
Border needed = perimeter of the rectangle = 57.5 feet
Width of the rectangle = 12.25 feet
Length of the rectangle = x feet
Perimeter of a rectangle = 2(Length + width)
57.5 =2(x + 12.25)
57.5 = 2x + 24.5
57.5 - 24.5 = 2x
33 = 2x
x = 33/2
x = 16.5 feet
Length of the rectangle = 16.5 feet

To answer this, find the area of each side, then add the values together.
Normally Surface Area = 2 (wl + hl + hw) but in this case, the easiest way to solve this is to divide the shape into 2 different rectangular prisms. Your new equation would be: SA = Sa₁ + Sa₂ or it could be
SA = [2 (wl + hl + hw)] + [2 (wl + hl + hw)]
We'll start by solving the surface area for the larger rectangular prism.
Sa₁ = 2 (wl + hl + hw) substitute w, l, and h
Sa₁ = 2 [(10)(0.5) + (12)(0.5) + (12)(10)]
Sa₁ = 2 (131)
Sa₁ = 262
Now do the same equation for the smaller rectangular prism
Sa₂ = 2 (wl + hl + hw) substitute w, l, and h
Sa₂ = 2 [(10)(0.5) + (4)(0.5) + (4)(10)]
Sa₂ = 2 (47)
Sa₂ = 94
Now add Sa₁ and Sa₂
SA = 262 + 94
SA = 356
