The triangle and the trapezoid have the same area. Base b2 is twice the length of base b1. What are the lengths of the bases of the trapezoid? The area of the triangle is 65 cm squared

Answers

Answer:

[tex]b_1 \approx 7.2[/tex]

[tex]b_2 \approx 14.4[/tex]

Step-by-step explanation:

Given

[tex]Area = 65cm^2[/tex] --- Area of the triangle

[tex]b_2 = 2b_1[/tex] --- the bases of the trapezoid

The missing parameters is:

[tex]h=6 cm[/tex] --- Trapezoid height

Required

Determine b1 and b2

Since the areas of the trapezoid and the triangle are the same, then:

[tex]Area = \frac{1}{2}(b_1 + b_2) *h[/tex]

So, we have:

[tex]65 = \frac{1}{2}(b_1 +b_2) * 6[/tex]

Substitute[tex]b_2 = 2b_1[/tex]

[tex]65 = \frac{1}{2}(b_1 +2b_1) * 6[/tex]

[tex]65 = \frac{1}{2}(3b_1) * 6[/tex]

[tex]65 = 3b_1 * 3[/tex]

[tex]65 = 9b_1[/tex]

Solve for [tex]b_1[/tex]

[tex]b_1 = \frac{65}{9}[/tex]

[tex]b_1 \approx 7.2[/tex]

Substitute [tex]b_1 \approx 7.2[/tex] in [tex]b_2 = 2b_1[/tex]

[tex]b_2 \approx 2 * 7.2[/tex]

[tex]b_2 \approx 14.4[/tex]

5hours
6hours
7hours
10hours
12hours

Answers

Answer:

10 hours

Step-by-step explanation:

Create a proportion where x is the number of hours to travel 5000 miles

[tex]\frac{1000}{2}[/tex] = [tex]\frac{5000}{x}[/tex]

Cross multiply and solve for x

1000x = 10000

x = 10

So, it will take 10 hours.

What are Quadratic Functions?

Quadratic functions are polynomial functions consisting of variables and exponents and the degree of the variable is 2.

The general form of a quadratic function is f(x) = ax² + b x + c.

Let f(x) = ax² + b x + c be the function required.

Roots are 6 and -2.

Equation can be written in the factorized form as,

(x - 6) (x + 2) = 0

x² - 6x + 2x - 12 = 0

x² - 4x - 12 = 0

f(x) = x² - 4x - 12

Vertex of a function f(x) = ax² + b x + c is (h, k) such that h = - (b/2a) and k = f(h)

h = - (-4/2) = 2

k = f(2) = 4 - 8 - 12 = -16

Hence the vertex of the function is (2, -16).

if the ratio of milk and water in 45 litre is 7:2. if 4 litre water is added what will be the new ratio.​

Answers

Answer:

5 : 2

Step-by-step explanation:

sum the parts of the ratio, 7 + 2 = 9 parts

Divide the quantity by 9 to find the value of one part of the ratio

45 litres ÷ 9 = 5 litres ← value of 1 part of the ratio , then

7 parts = 7 × 5 = 35 litres

2 parts = 2 × 5 = 10 litres

In 45 litres there is 35 litres of milk and 10 litres of water

Adding 4 litres of water gives

35 : 14 = 5 : 2

will take for the pinecone to reach the ground.
A. 4 seconds
B. 6 seconds
C. 2 seconds
D. 1.5 seconds

Answers

Answer:

4 Seconds

Step-by-step explanation:

Let's say the height of the ground is set at y = 0.

Then, since 16 times 4 is 64, we substitute 4 for x.

But wait! x is being squared!

So we need to find out what squared is 4. It's 2.

So, with x being equal to two, y is equal to 0.

But what is the number of seconds? We actually got it first.

That means that the answer is 4.

The pinecone takes 4 seconds to reach the ground.

solve for x.
hint: use your knowledge of parallel lines. what do you know about these angles? are they congruent or supplementary?

Answers

Answer:

Step-by-step explanation:

The given angles are supplementary which means their sum is 180

8x + 92 = 180 subtract 92 from both sides

8x = 88 divide both sides by 8

Step-by-step explanation:

regular hexagon is made up of 6 equilateral triangles. All sides are equal

The formula for finding the area of a hexagon is Area = (3√3 s2)/ 2 where s is the length of a side of the regular hexagon.

Side big hexagon = 12

side small hexagon = 6

BIG    A=  (3√3 144)/ 2 =   374.1230...

small  (3√3 36)/ 2 = 93.5307...

shaded = BIG minus small

I had trouble plotting the midpoint lol but can someone plz help me :c​

Answers

midpoint is (-1 and -1.5)

Answer:

Step-by-step explanation:

midpoint rule is    x2+x1 / 2  , y2+y1 / 2

where point one is P1 = (x1,y1) = (4,3)

and point two is P2 = (x2,y2) = -6,-6

for x   then,  -6+4 / 2 = -2 / 2   =  - 1

for y then,  -6+3 / 2 = -3 / 2  =  - [tex]\frac{3}{2}[/tex]

Answers

Answer:

(-6.5, 3)

7.2units

Step-by-step explanation:

Given the coordinate

A =(-26, -15)

B = (13, 21)

Midpoint of A and B is expressed as;

X = -26+ 13/2

X = -13/2

X = -6.5

Y = -15+21/2

Y = 6/2

Y = 3

Hence the required midpoint is (-6.5, 3)

b) The distance between the coordinate (-6.5, 3) and (0,0) is expressed as;

D = √(-3)²+(0+6.5)²

D = √9+42.25

D = √51.25

D = 7.2units

Hence the distance between the  midpoint and the base camp is 7.2units
