Let the base angle be x. If the obtuse angle is two and a half times the base angle, it will be 2.5x. In a triangle, all three angles will add up to 180. The third angle, the other base angle will be equal to x. So the equation will be:

x + x + 2.5x = 180
2x + 2.5x = 180
4.5x = 180
x = 40

If x = 40, then 2.5x = 100

The North Carolina Aquarium at forth fisher celebrated a record amount of visitors on Memorial Day.they recorded 16,652 visitors
Lena [83]

<u>Answer:</u>

Option(b) = 10

The Number 6 in the thousands place is 10 times bigger than the Number 6 in the hundreds place

<u>Explanation:</u>

We are given the value recorded = 16,652

Now the Number 6 in hundreds place means it is equal to 600 and the  Number 6 in thousands place means that it is = 6000

from the given value 6 in hundreds place = 652 and

that in thousands place = 6520 ,

so the six in thousands place is obtained by multiplying 10 with the 6 in hundreds place hence the latter is 10 times bigger than the former.

Mrs. Start's class paid $5.60 for 4/5 yd of lace for an art project. Later, the class decided to buy another 7 3/4 yd of the sam
MissTica

Answer:

$54.25

Step-by-step explanation:

4/5 yards of lace = $5.60

Price per yard = 5.60 ÷ 4/5

= 5.60 × 5/4

= 28 /4

= $7 per yard

The class decided to buy another 7 3/4 yd

Cost of 7 3/4 yd = cost per yard × number of yards

= $7 × 7 3/4

= $7 × 31/4

= 217 / 4

= $54.26

Cost of 7 3/4 yd = $54.25

The sum of 2 numbers is 49. The second number is 15 less than the first number. The first number is
liubo4ka [24]

Answer:

x + y = 49

y = x - 15

Step-by-step explanation:

The sum of 2 numbers is 49 means that x+y = 49. (The two numbers are x and y, and the sum of them are 49.)

The second number is 15 less than the first number, means that y = x - 15 (The second number is y, and it is 15 less than x, which is the first number.)

Therefore the equations will be

x + y = 49

y = x - 15
