Answer:

8 small tables

Step-by-step explanation:

they told you they have 5 large tables that seat 10 guests and 98 guests are coming. You need to subtract 50 from 98 because after you multiple how many guests can sit at each large table by how many large tables they have it equals 50 so 98-50=48 then you need to divide 48 by six because each small table sits six people so 48/6=8 so you need 8 small tables.

Which expression is equivalent to 2.2 − 0.5(0.6x − 1.8) ?
yawa3891 [41]

Answer:

D is equivalent to the expression.

Step-by-step explanation:

The expression that is given equals 2.8, or 2.8x.

A. This expression equals 1.6x, and 1.6x is not equivalent to 2.8x

B. 0.3x + 3.1 = 3.4x. This doesn't have the answer of 2.8x.

C. 1.3 - 0.3x = 1 or x.

D. 3.1 - 0.3x = 2.8x. D is the answer.

Calculate each unknown side length. Round your answer to the nearest tenth.
Mumz [18]

1. y=12.6 units

2. x=25.30 units

3. x=5.70 units, y=11.50 units

4. x=4.10 units, y=11.50 units.

Step-by-step explanation:

In all cases, apply the Pythagorean relationship where the sum of the squares of the sides equals the square of the hypotenuse.

a²+b²=c² where a and b are the sides, and c is the hypotenuse

1.

In this question;

First find b, where c=5  and a is 4

a²+b²=c²

4²+b²=5²

16+b²=25

b²=25-16=9

b=√9=3 units

To get y apply the formula now where c=13 and b=3

y²+3²=13²

y²+9=169

y²=169-9=160

y=√160=12.6 units.

2.

The triangle with a hypotenuse of 20 in is a right-isosceles triangle.

In this triangle apply the sine of an angle law to get the height of the triangle where the angle is 45°

Sin 45°=opposite side length/hypotenuse length

sin 45°=h/20

h=20*sin 45°=14.10 units

Use the height to find the side length for the small triangle when now c=18 and b=14.10

a²+b²=c²

a²+14.10²=18²

a²=18²-14.10²

a²=11.20

Now x= 11.20+14.10 =25.30 units

3.

In this case first find length of x given b=4 and c=7

a²+b²=c²

x²+4²=7²

x²+16=49

x²=49-16

x²=33

x=√33 =5.70 units

Now find y using a=x=5.70 and b=6+4=10

a²+b²=c²

5.70²+10²=c²

132.49=c²

√132.49=c

11.50=c=y

y= 11.50 units

4.

First find x where b=8 and c=9

x²+8²=9²

x²=9²-8²

x²=17

x=√17 =4.10 units

Now find y where b=8, a=(4.10+4.10)=8.20 ----because you have two equal sides

a²+b²=c²

8.20²+8²=y²

131.24=y²

√131.24=y

11.50 units = y
