1/4 + 1/2 + 1/2 = ? (Show ur work)

kaheart [24]

Answer:

1.25 = 1 1/4

Step-by-step explanation:

1/2+1/2 = 0.5+0.5 = 1

1+1/4 = 1+0.25 = 1 1/4 = 1.25

1/2 x 2 = 0.5 x 2 = 1 + 1/4 = 1 + 0.25 = 1.25

Answer:

y = 3x + 3

Step-by-step explanation:

y = mx + b where m= slope and b= y-intercept

the y-intercept is the point where x=0 or where the line crosses the y-axis.

This happens at (0,3) on the graph, so the y-intercept, or b, is equal to 3.

for m, slope can be defined as rise/run. So starting from a point you are given on the graph (-1,-2), count the number of spaces up you rise and how many you must go over (run) to get to the next point (0,3)

if you count, you should rise from (-1,-2) 5 spaces and move to the right (run) 1 space to get to (0,3).

rise/run = 3/1

3/1 = 3

the slope is 3.

now that you have the slope and the y-intercept, you can just plug it into the equation

y = 3x + 3

Point C is in the interior of ∠ABD, and ∠ABC ≅ ∠CBC. If m∠ABC = (5/8x + 18) and m∠CBD = (4x), what is m∠ABD?

mixer [17]

Answer:

$\angle ABD =42.4^{\circ}$

Step-by-step explanation:

We are given that Point C is in the interior of ∠ABD

We are also given that ∠ABC ≅ ∠CBD

Now ,

$\angle ABC = (\frac{5}{8}x + 18)\\\angle CBD = (4x)$

Since we are given that ∠ABC ≅ ∠CBD

So, $\frac{5}{8}x + 18=4x\\4x-\frac{5}{8}x=18\\\frac{32x-5x}{8}=18\\\frac{27x}{8}=18\\x=\frac{18 \times 8}{27}\\x=5.3$

$\angle CBD = (4x)=4(5.3)=21.2^{\circ}$

$\angle ABD = \angle CBD+\angle ABC=21.2+21.2=42.4^{\circ}$

Hence $\angle ABD =42.4^{\circ}$

Jasmyn is standing at the point of tangency to a wishing

timofeeve [1]

Answer:

The value of $x=17 ft$ .

Step-by-step explanation:

Diagram of the given scenario shown below.

Given that,

Distance from bench to Jasmyn is $PA=27ft$ .

Distance from bench to Willard is $PB=(2x-7)ft$ .

From the Question,

The given wishing well is a circle and all the distance are tangent to the circle.

So, Triangle formed by these points are such as Δ $PAO$ and Δ $PBO$ .

Now, taking both Δ $PAO$ and Δ $PBO$ .

⇒ $AO = BO$ {Radius of circle are equal}

⇒ $PO=PO$ {Common side}

⇒ ∠ $PAO =$ ∠ $PBO$ {radius is always perpendicular

to the point of tangent }

∴ Δ $PAO$ ≅ Δ $PBO$ {By SAS congruence theorem}

Therefore, $PA=PB$ ....(1) {corresponding part of

congruence triangle (CPCT)}

Thus,

⇒ $2x-7=27$ {from equation (1)}

⇒ $2x=34$

⇒ $x=17 ft$

Hence, The value of $x=17 ft$ .
