Angle AOD = 180
4x-2 + 5x+10 + 2x+14 = 180
11x + 22 = 180
11x = 180 - 22 = 158
x = 158/11

Jane buys \dfrac73 \text { yard} 3 7 ​ yardstart fraction, 7, divided by, 3, end fraction, start text, space, y, a, r, d, end te
Vadim26 [7]

The correct question is:

Jane buys 7/3 yards of fabric to make a cat bed. She starts the project by cutting 4 feet of fabric off the end. How many feet long is the remaining piece of fabric?

Answer:

There are 3 feet remaining.

Step-by-step explanation:

Jane cuts 4 feet from 7/3 yards, to know how many feet long yard is remaining, first we need to know how many feet make a yard, convert 7/3 yards to feet, and find the difference between the feet cut and the total feet available.

3 feet = 1 yard

x feet = 7/3 yards

3 × 7/3 = x × 1

x = 7

Therefore, 7 feet is 7/3 yards.

Now, she cuts 4 feet, do we have

(7 - 4 = 3) feet remaining.

Therefore, there are 3 feet remaining.

If henry were to add 5 gallons of water to a tank that is already 34 full of water, the tank would be 78 full. how many gallons
taurus [48]
Please express those fractions properly:  3/4, 7/8.

Let g be the # of gallons the tank could hold when full.  

Then (3/4)n + 5 = (7/8)n.  

solving for n:  Mult all 3 terms by the LCD (8):  6n + 5(8) = 7n.

Then n=5(8) = 40 (gallons).  The tank would hold 40 gallons of water were it full.

Given: EFGH inscribed in k(O) m∠FHE = 45°, m∠EGH = 49° Find: m∠FEH
hodyreva [135]

Answer:

m

Step-by-step explanation:

we know that

The inscribed angle measures half that of the arc comprising

step 1

Find the measure of arc EF

m

we have

m

substitute

45\°=\frac{1}{2}(arc\ EF)

arc\ EF=90\°

step 2

Find the measure of arc EH

m

we have

m

substitute

49\°=\frac{1}{2}(arc\ EH)

arc\ EH=98\°

step 3

Find the measure of arc FGH

arc\ FGH=360\°-(arc\ EH+arc\ EF)

substitute the values

arc\ FGH=360\°-(98\°+90\°)

arc\ FGH=172\°

step 4

Find the measure of angle FEH

m

we have

arc\ FGH=172\°

substitute

m

A study was conducted to determine the percent of children that want to grow up work in the same career as a parent. In a sample
Irina-Kira [14]

Answer:

Step-by-step explanation:

From the information given,

Number of sample, n = 200

Probability of success, p = 43/100 = 0.43

q = 1 - p = 1 - 0.43

q = 0.57

For a confidence level of 95%, the corresponding z value is 1.96.

The formula for determining the error bound for the proportion is

z × √pq/n

= 1.96 ×√(0.43 × 0.57)/200

= 1.96 × 0.035 = 0.0686

The upper boundary of the population proportion is

0.43 + 0.0686 = 0.5

The lower boundary of the population proportion is

0.43 - 0.0686 = 0.4

The error in the solution is

phat = 0.43/200 = 0.00215

Also,

[-0.0043, 0.0086] is wrong
