diameter of 16 in. How much
space will the clock cover on
his wall?

Answer:y=5x+1

Step-by-step explanation:the y intercept is the y value when x=0 which we can read off as run. Slope =rise/run=(change in y value)/(change in x value) for any two points.

Answer: I think

Step-by-step explanation:Let the coordinate of the point be (x,y,z). Since the point is located 3 units behind the YZ− plane, 4 units to the right of XZ− plane and 5 units above the XY−plane ,x=−3,y=4 and z=5 Hence, coordinates of the required points are (−3,4,5)

Answer:

the lenght of the segment ab is 15 inches

Abby can make 5 complete groups with 9 extra bonus coupons.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Here, Abby has total number of coupons = 159

        Number of coupons in a group = 30

Total number of groups = Total Coupons / coupons in a group

                                         = 159 / 30

                                         = 5.3

Thus, Abby can make 5 complete groups with 9 extra bonus coupons.

Given the charges for a football and the tax rate, the total price to purchase a football is $23.6698.

Given that;

First, we calculate the tax price on the football.

Tax price = Tax rate × Charges for the football

Tax price = 6% × $22.33

Pax price = 0.06 × $22.33

Tax price = $1.3398

Now, total price to purchase football will be;

Total price = Charges for a football + Tax price

Total price = $22.33 + $1.3398

Total price = $23.6698

Given the charges for a football and the tax rate, the total price to purchase a football is $23.6698.

The general form of the equation for the given circle centered at O(0, 0) is x² +y² - 41=0.

The correct option is (B).

The general equation for a circle is ( x - h )² + ( y - k )² = r², where ( h, k ) is the center and r is the radius.

as, general equation for a circle is ( x - h )² + ( y - k )² = r²

Here,  centered at O(0, 0).

So,

a =0 and b = 0

now, r² = (BO)²

r² = (4-0)² +(5-0)²

r²  = 16+25

r² = 41

Hence, Center at the origin passing through B(4, 5) is x² +y² = 41.

Step-by-step explanation:

length = the original length

width = the original width

length = width + 10 or

width = length - 10

(length + 4) × (width + 8) = 135

A

now we are using the first equation in the second to solve then for length :

(length + 4) × (length - 10 + 8) = 135

(length + 4) × (length - 2) = 135

length² - 2×length + 4×length - 8 = 135

length² + 2×length = 143 or

length² + 2×length - 143 = 0

this is the equation to model the scenario.

solving in general such a quadratic equation :

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

x = length

a = 1

b = 2

c = -143

length = (-2 ± sqrt(2² - 4×1×-143))/(2×1) =

= (-2 ± sqrt(4 + 572))/2 =

= (-2 ± sqrt(576))/2 =

= (-2 ± 24)/2 = (-1 ± 12)

length1 = -1 + 12 = 11

length2 = -1 - 12 = -13

a negative solution for a length is not applicable, so,

length = 11

width = length - 10 = 11 - 10 = 1

B

the expanded length = 11 + 4 = 15

the expanded width = 1 + 8 = 9

the expanded perimeter is then

2×15 + 2×9 = 30 + 18 = 48

Method

Inversely in this sentence means

y = k/x    

So you first step is to find the value of k. You do that by setting up an inverse relationship with y = 2 , x = 5

2 = k/5                     Multiply both sides by 5

2*5 = 5*k/5

10 = k

Now you are able to answer the question.

y = 10/x

3= 10/x                      Multiply both sides by x

3*x = x * 10/x

3x = 10                      Divide both sides by 3

3x/3 = 10/3

x = 3.33 or x = 3 1/3

Answer

x = 3.33 or x = 3  1/3

Answer:

35°

Step-by-step explanation:

If 2 angles are supplementary, that means they add up to 180 :

Now we make an equation and solve for x :

(4x+9) + (x+1) = 180

5x+10 = 180

5x = 170

x = 34

Now we find the measure of the smaller angle using our value of x :

x+1 = 34 +1

x+1 = 35

Quadrilateral:  shape with 4 sides

Perpendicular means at right angles.  Therefore, draw two sides at a right angles to each other.  Mark this with a right angle symbol.

Draw 2 sides that are parallel.  Mark these with arrows.

By using the Pythagoras theorem, the length of the ladder will be 13.6 feet.

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The Pythagoras theorem formula is given as

H² = P² + B²

Jennifer needs to use a ladder to clean a second-floor window on a building.

If the window is 13 ft above the ground and the base of the ladder is 4 ft from the building.

Then the length of the ladder will be

H² = 13² + 4²

H² = 169 + 16

H² = 185

H = 13.6 ft

y represents the height.

g is 9.8 m/s²

t represents the falling time of the lava rocks.

Answer:

14) x = 30°

15) x = 50°

Step-by-step explanation:

14) 60 + x = 90

     x = 90 - 60

     x = 30°

15) 130 + x = 180

     x = 180 - 130

     x = 50°

Hope this helps

Step-by-step explanation:

Is first image we are given a right angle and we know that right angle = 90°

So,

60 + x = 90

x = 90 - 60 = 30°

x = 30°

In the second image we are given a straight line and we know that on the 180° angle is a straight line.

so,

130 + x = 180

x = 180 - 130

x = 50°
