Answer:

The slope is y= 1/1 - 2

Step-by-step explanation:

If you look at the graph, you will see that the points of the line go up one step and over one step each time. Then, the y-intercept is at -2. (This is where the line intersects the y-axis)

Find the volume of a pyramid with a square base, where the side length of the base is

vivado [14]

Answer:

Volume of the pyramid = 927.72 m² (Approx)

Step-by-step explanation:

Given:

Length of base = 16.6 m

Height of the pyramid = 10.1 m

Find:

Volume of the pyramid = ?

Computation:

Area of the square base = Side²

Area of the square base = (16.6)²

Area of the square base = 275.56 m²

$Volume\ of\ the\ pyramid = \frac{1}{3}(Area\ of\ base)(Height)\\\\Volume\ of\ the\ pyramid = \frac{1}{3}(275.56)(10.1)\\\\Volume\ of\ the\ pyramid = 927.7186$

Volume of the pyramid = 927.72 m² (Approx)

Randi and her sister make balloon animals and sold them for $.50 each. They made $48.00. If rando made twice as many animals as

nydimaria [60]

Randy made 64 ballon animals and her sister made 32 ballon animals

Solution:

Let the number of ballon animals sold by Randi be "x"

Let the number of ballon animals sold by her sister be "y"

Cost of 1 ballon animal = $ 0.50

Rando made twice as many animals as her sister

Number of ballon animals sold by Randi = twice the number of ballon animals sold by her sister

x = 2y ---- eqn 1

Together, they earned $ 48

Therefore, we can frame a equation as:

Number of ballon animals sold by Randi x Cost of 1 ballon animal + number of ballon animals sold by her sister x Cost of 1 ballon animal = 48

$2y \times 0.50 + y \times 0.50 = 48$

$1y + 0.5y = 48\\\\1.5y = 48\\\\y = \frac{48}{1.5}\\\\y = 32$

Therefore, from eqn 1

x = 2y

x = 2(32)

x = 64

Thus Randy made 64 ballon animals and her sister made 32 ballon animals

A 4 metre ladder is placed against a vertical wall.

Black_prince [1.1K]

Answer:

Original position: base is 1.5 meters away from the wall and the vertical distance from the top end to the ground let it be y and length of the ladder be L.

Step-by-step explanation:

By pythagorean theorem, L^2=y^2+(1.5)^2=y^2+2.25 Eq1.

Final position: base is 2 meters away, and the vertical distance from top end to the ground is y - 0.25 because it falls down the wall 0.25 meters and length of the ladder is also L.

By pythagorean theorem, L^2=(y -0.25)^2+(2)^2=y^2–0.5y+ 0.0625+4=y^2–0.5y+4.0625 Eq 2.

Equating both Eq 1 and Eq 2: y^2+2.25=y^2–0.5y+4.0625

y^2-y^2+0.5y+2.25–4.0625=0

0.5y- 1.8125=0

0.5y=1.8125

y=1.8125/0.5= 3.625

Using Eq 1: L^2=(3.625)^2+2.25=15.390625, L=(15.390625)^1/2= 3.92 meters length of ladder

Using Eq 2: L^2=(3.625)^2–0.5(3.625)+4.0625

L^2=13.140625–0.90625+4.0615=15.390625

L= (15.390625)^1/2= 3.92 meters length of ladder

Help pls!! .........................................................................

ser-zykov [4K]

Answer:

a)8

b)13

Step-by-step explanation:

a) ar = c

a^2+b^2=c^2

4^2+7^2=c^2

16+49 = c2

c = $\sqrt{65}$ ~8

b) sa= c

a2+b2=c2

7^2 + (15-4)^2

49+121 = c2

c= $\sqrt{170}$ = 13

I hope im right!!
