Jose has $20 more than Sarah. Their combined mobey totals $90. Write and solve an algebric model to determine the amount of mone
scoray [572]

Let S= the amount of money Sarah has.

Let J= the amount of money Jose has

J= S+20

J+S=90

But we also know that J can equal S+20

So,

S+20+S=90

2S+20=90

2S=70

S=35

So Sarah has $35, and Jose has $35+$20, so he has 55$

A 36-foot-tall tree casts a 9-foot shadow. How tall is a nearby tree that casts a 14-foot shadow at the same time?
kiruha [24]

Answer:

Proportion states that the two fractions or ratios are equal.

Given the statement: A 36-foot-tall tree casts a 9-foot shadow.

To find the height of the nearby tree that cast a 14 foot shadow at the same time.

Let x be the height of the nearby tree.

By definition of proportion;

\frac{\text{Height of thetall tree}}{\text{Shadow of the tall tree}} =\frac{\text{Height of the nearby tree}}{\text{Shadow of the nearby tree}}

Substitute the given values we get;

\frac{36}{9}=\frac{x}{14}

Simplify:

4 = \frac{x}{14}

Multiply both sides by 14 we get;

x= 4 \times 14 = 56 foot.

therefore, the height of the nearby tree is, 56 foot.

Answer:

192.5 ft²

Step-by-step explanation:

Area of the shaded region (A) = Area of the major sector + Area of the triangle.

A = (πr²θ/360)+(r²sinα)/2............. Equation 1

From the diagram,

Given: r = 8.35 ft, α = 100°, θ = 360-100 = 260°

Substitute these values into equation 1

A = (3.14×8.35²×260/360)+(8.35²×sin100×1/2)

A = 158.16+34.33

A = 192.49 ft²

A  = 192.5 ft²

Hence the area of the shaded region = 192.5 ft²
