Answer:

z=116 (opposite angles are equal)

y=180-(116+27)=37(angles in a triangle sum up to 180)

(z) + (27+x) =180(interior angles on same side are supplementary

116 + 27+ x =180

x= 37

Using the following equation, find the center and radius of the circle. You must show all work and calculations to receive credi

Vikki [24]

The equation of the circle: $(x-a)^2+(y-b)^2=r^2$

where:
(a; b) - coordinates of the center
r - a radius

Use: $(a\pm b)^2=a^2\pm2ab+b^2\ \ \ \ (*)$

We have:

$x^2-4x+y^2+8y=-4\\\\x^2-2x\cdot2+y^2+2y\cdot4=-4\ \ \ |add\ 2^2\ and\ 4^2\ to\ both\ sides\\\\\underbrace{x^2-2x\cdot2+2^2}_{(*)}+\underbrace{y^2+2y\cdot4+4^2}_{(*)}=-4+2^2+4^2\\\\(x-2)^2+(y+4)^2=-4+4+16\\\\(x+2)^2+(y-4)^2=16\\\\(x+2)^2+(y-4)^2=4^2$

Answer:
The center: (-2; 4)
The radius: r = 4

What is the answer to 1/7(x+3/4)=1/8

ivolga24 [154]

Answer:

Step-by-step explanation:

1/7(x+3/4) = 1/8

Multiply 1/7 with x and 3/4

1/7x + 3/28 = 1/8

Multiply everything by 7, so x is a whole number

x + 21/28 = 7/8

Convert 21/28 into a similar like denominator to 7/8

x + 6/8 = 7/8

x = 7/8 -6/8

x = 1/8

Step 2: Now click the button “Solve” to get the answer

Step 3: Finally, the significant figures of the number will be displayed in the output field

What is Meant by Significant Figures?

In Mathematics, the significant figures define the number of important single digits that contribute to the degree of accuracy of the given number. The five important rules for the significant figures are as follows:

All the non zero numbers are significant figures

The zero present in between the non zero numbers are significant figures

The leading zeros are not significant

The trailing zeros present at the right side of the decimal point are significant figures

Trailing zeros of the number without a decimal point are not significant figures

The trailing zeros present in the whole number with the decimal point are significant figures

VERY URGENT.

NemiM [27]

Answer:

(1)Base Area= 81 square yards.

(2)

3 ft long and 16 ft wide

6 ft long and 8 ft wide
24 ft long and 2 ft wide

(3)Height=12 Units

Step-by-step explanation:

<u>Question 1</u>

Volume of the rectangular prism=2,592 cubic yards.

Height of the rectangular prism=32 yards

Volume of a rectangular prism =lbh (where lb is the Base Area)

Therefore:

lbh=2592

32lb=2592

lb=2592/32=81

Base Area= 81 square yards.

<u>Question 2</u>

Volume of the rectangular prism=432 cubic feet.

Height of the rectangular prism=9 feet

Volume of a rectangular prism =lbh (where lb is the Base Area)

Therefore:

lbh=432

9lb=432

lb=432/9=48

Base Area= 48 square yards.

Any dimension whose product is 48 is a possible choice.

They are:

3 ft long and 16 ft wide
6 ft long and 8 ft wide
24 ft long and 2 ft wide

<u>Question 3</u>

<u />

Volume of the rectangular prism=960 cubic units.

Base Area of the rectangular prism, lb=80 Square Units

Volume of a rectangular prism =lbh (where lb is the Base Area)

Therefore:

lbh=960

80h=960

h=960/80=12

Height= 12 units.
