Step-by-step explanation:
2(heads) + 2(goats) = 140
Heads are given, so we get:
2(52) + 2(goats) = 140
104 + 2(goats) = 140
2(goats) = 36
goats = 18
Since we know the number of goats, we know the number of chickens.
34Chickens and 18 goats.

You buy a new motorcycle for $15,500. Its value depreciates by 8.5% each year. In how many years will it be worth only a tenth of what you paid for it?
a. 26
b. 27
c. 24
d. 25
Answer:
a. 26
Step-by-step explanation:
The formula for depreciation is given as
y = a(1 - r)^t
a = Initial value = $15,500
y = Current value = 1/10 of Initial value = $1,550
r = depreciation rate = 8.5% = 0.085
t = time in years = ?
Hence,
1550 = 15500(1 - 0.085)^t
1550 = 15500(0.915)^t
Divide both sides by 15500
1550/15500 =(0.915)^t
0.1 = (0.915)^t
Take the Logarithm of both sides
log 0.1 = log(0.915)^t
log 0.1 = t log (0.915)
Divide both sides by log 0.915
t = log 0.1/log 0.915
t = 25.920900964 years
Approximately Time t = 26 years
Option a is correct

In a video game, Val scored 30%, percent fewer points than Peeta. Peeta scored 1060 points.
Answer:
742
Step-by-step explanation:
Divide 1060 by 10 to get 106. This is 10% of his score.
100-30 is 70, so Val scored 70% of Peeta’s points.
Multiply 106 by 7 find 70%
Val scored 742 points

In the diagram, line m is tangent to the circle and m overline CAB =278°. Find m < CBE .
The angle m∠CBE between the intersection of the chord and tangent line is equal to 41°
How to calculate for angle between the intersection of a chord and a tangent.To calculate for the angle between the intersection of a chord and a tangent we need to know the measure of the intercepted arc, and then divide it by 2 to get the angle.
If the measure of the arc CAB is given to be equal to 278°, then the measure of intercepted arc BC is calculated as:
arc BC = 360 - 278
arc BC = 82°
angle CBE = 82°/2
m∠CBE = 41°
Therefore, the angle m∠CBE between the intersection of the chord and tangent line is equal to 41°

Answer:
1) 2400 sq feet
2) $93.75
3) A (first answer)
Step-by-step explanation:
1) replace the 6 inches with 60 feet and 4 inches with 40 feet. We do this bc 1 inch = 10 feet. Then multiply 60 x 40 to get 2400 sq feet
2) we know that 25% off of 100 is 75. Then to add 25% back to 75 we find 25% of 75. 25% of 75 is 18.75. So we add 18.75 + 75 to get $93.75

Bob can type 2 letters in 4 hours while bill can do it in six. How many hours will it take them, working together, to type six letters
Answer:
7hr 12 min
Step-by-step explanation:
Given that
Bob can type 2 letters in 4 hours
while on the other hand bill can do it in six hours
We need to find out the no of hours in which they type 6 hours
So,
Bob's rate is
= 2 ÷ 4
= 1 ÷ 2 letter per hour
And,
Bill's rate is
= 2 ÷ 6
= 1 ÷ 3 letter per hour
Now
Together rate is
= 1 ÷ 2 + 1 ÷ 3 = 5 ÷ 6 letter per hour
We know that
rate × hours = production
Let us assume the hours be x
So,
(5 ÷ 6)x = 6
x = (6 ÷ 5) × 6
x = 36 ÷ 5
= 7 1 ÷ 5
= 7hr 12 min
The can shown has a diameter of 3 inches and a height of 5 inches. Find the lateral surface area of the can.
Answer:
Lateral surface area of can = 47 inch² (Approx.)
Step-by-step explanation:
Given:
Diameter of given can = 3 inches
Height of given can = 5 inches
Find:
Lateral surface area of can
Computation:
Radius of can = 3 / 2 = 1.5 inch
Lateral surface area of can = Lateral surface area of cylinder
Lateral surface area of cylinder = 2πrh
Lateral surface area of can = 2πrh
Lateral surface area of can = 2(3.14)(1.5)(5)
Lateral surface area of can = 47.1
Lateral surface area of can = 47 inch² (Approx.)

How to determine the value of x?The figure illustrates similar triangles.
This is represented by the following equivalent ratios
x : 6 = 4 : 8
Express as fraction
x/6 = 4/8
Multiply both sides by 6
x = 6 * 4/8
Evaluate the product
x = 3

All lines are congruent to one another.
Answer:
This is false. Lines will be congruent if they have the same length, which is not the case in all situations.
Answer:
Line segments are congruent if they have the same length. However, they need not be parallel. They can be at any angle or orientation on the plane. In the figure above, there are two congruent line segments.

A rectangle has a length of (x+5)and a with of x Write down the expression for the area of a rectangle If the area is 24cm²,find the value of
Answer: Width = 3cm
Length = 8cm
Step-by-step explanation:
Length = x+5 cm
Width = xcm
Area = 24cm²
Area of a rectangle = length × width
x × (x + 5) = 24
x² + 5x = 24
x² + 5x - 24 = 0
x² + 8x - 3x - 24 = 0
x(x + 8) - 3(x + 8) = 0
x - 3 = 0
x = 3
Width = 3cm
Since length = x + 5 = 3 + 5 = 8cm
Length = 8cm
What percent of babies born in the United States are classified as having a low birth weight (< 2,500 g)? Explain how you got your answer.
Answer:
1.42%Step-by-step explanation:
Infants born with a birth weight less than 1500 g are defined as very low birth weight (VLBW) infants. Approximately 3,952,841 US births were reported in 2012. Low birth weight (< 2500 g) was noted in 7.99% of the births, and VLBW was noted in 1.42% of all births.The table shows the results of a survey at a local school. The survey asked 7th and 8th graders if they pack their lunches or if they buy their lunches in the school cafeteria. Here are the results.
47 seventh graders were surveyed and 19 of them pack their lunches.
52 eighth graders were surveyed and 33 of them buy their lunches.
Construct a two-way frequency table for the data.
Answer: The table is shown in the attached image
Row One: 19, 28, 47Row Two: 19, 33, 52Row Three: 38, 61, 99The commas are not to be entered in any of the boxes. Just the numbers only.
=====================================================
Explanation:
"47 seventh graders were surveyed" means that 47 goes in the last value of the first row. This is the total of the 7th graders. Of this total, 19 pack their lunches (ie bring them from home). That indicates 47-19 = 28 seventh graders buy their lunch.
For row one, we have the values: 19, 28, 47 in that exact order when going from left to right.
------------------
We use the same idea for the 8th graders.
52 total eighth graders, 33 buy their lunch
52-33 = 19 pack their lunch
For row two, the values from left to right are: 19, 33, 52 in that exact order.
To get the values in row 3, we add up everything that's over top of it.
Meaning for column 1, we have 19+19 = 38 total students who pack their lunch. In column 2, there are 28+33 = 61 people who buy their lunch. Lastly, column 3 we have 47+52 = 99 students overall.
For row three, the values from left to right are: 38, 61, 99
Note that adding the first two items of row three gets us 38+61 = 99
It's not a coincidence that this is happening. This is just another way to get the grand total of 99. You could also add up the four values that are not in the total column or total row to get 19+28+19+33 = 99. Again, this is not a coincidence we end up with 99.
