Answer 1

Answer:

combined means to add so you are going to add anything over 1 because it says longer than 1

1 1/4 has 2 marks so you add 1 1/4 + 1 1/4 =

they have like denominators so you can add them together

1 + 1 = 2 and 1/4 + 1/4 = 2/4 which can be reduced to 1/2

so your answer is 2 1/2

The shoreline of Great Bear Lake is approximately 2719 km (not counting islands). If a map is drawn with a scale of 3 cm:100 km, how long would the shoreline be on the map?

Answers

Answer:

81.57 cm

Step-by-step explanation:

Given that :

Scale :

3cm : 100km

This means ; 3cm on the map represents an actual length of 100km

Actual length of shoreline = 2719 km

The length of the shoreline on the map will be :

(2719 km / 100 km) * 3cm

27.19 * 3cm

= 81.57 cm

Answer:

81.57 cm

Very much struggling with geometry right now, would appreciate the help ❤️

Answers

Answer: x= 30

Step-by-step explanation:

These are corresponding angles which means they are equal. (2x+25) = (3x-5). Subtract 2x from both sides. 25 = x-5. Add 5 to both sides. 30 = x

On a windless day In Janurafy, Carl ties 300 helium filled balloons to his lawn chair 80ft from his 20ft tall house, and begins a vergical ascent into the sky. Hos high is carl when the angle lf depression from carl to the top of his house is 42°

Answers

Answer:

The answer is below

Step-by-step explanation:

θ = 90° - 42° = 48°

The angle formed is a right angled triangle, therefore trigonometric identities can be used to find the length of the triangle sides.

tan(θ) = opposite / adjacent

tan(48) = 80 / h

h = 80 / tan(48)

h = 72.03 ft

h is the vertical distance from carl to the top of his house, to get his total height to the ground (H), we use:

H = h + height of house

H = 72.03 + 20

H = 92.03 ft

Therefore Carl is 92.03 ft high

Find an expression which represents the difference when (6x-3y) is subtracted from (9x+2y) in simplest terms.

Answers

Answer:

[tex]3x+5y[/tex]

Step-by-step explanation:

Subtract (6x-3y) from (9x+2y):

[tex](9x+2y)-(6x-3y)[/tex]

This can also be seen as:

[tex](9x+2y)-1(6x-3y)[/tex]

Distribute the -1 to (6x-3y):

[tex](9x+2y)-1(6x)-1(-3y)\\\\(9x+2y)-6x+3y[/tex]

Simplify the parentheses:

[tex]9x+2y-6x+3y[/tex]

Group like terms:

[tex](9x-6x)+(2y+3y)[/tex]

Combine:

[tex]3x+5y[/tex]

This expression can't be further simplified. Therefore, 3x+5y is the answer.

Answer:

13.7ft^2

Step-by-step explanation:

Area for triangle:

The formula for the area of a triangle in this scenario is area=(b*h)/2

The base length is 3.6ft and the height is 4.8ft. We can now substitute these values into the equation. So:

area=(3.6*4.8)/2

area=8.64ft^2 for the triangle

Area for semi-circle:

The formula for the area of a circle is area=pi*r^2. To find the area of the semi-circle, we can half the area of the circle at the end.

The question says to use 3.14 for the value of pi.

The diameter is given as 3.6ft, so to find the radius, we simply divide the diameter by 2; so 3.6/2=1.8ft for the radius

Now, we can just substitute these values into the equation above. So:

area=3.14*(1.8)^2

area=3.14*3.24

area=10.1736ft^2 (DO NOT ROUND THIS ANSWER!!).

However, this area is for the COMPLETE circle. We want the area for the semicircle shown above. Therefore, divide the circle area by 2. So:

10.1736/2=5.0868ft^2 for the semicircle.

Total area of shape

Now we have the area of the two separate shapes, we can simply add them together. So:

8.64ft^2 + 5.0868ft^2 = 13.7268ft^2 altogether (unrounded)

Now, finally we must round to 1/10, or to 1 decimal place. Therefore, the final value for the area would be 13.7ft^2.

Hope this helped!!

Find the area of the trapezoid. A drawing of a trapezoid with length of two parallel sides equal to a mixed fraction of one and a half centimeters and three and a half centimeters. The altitude of the trapezoid is 4 centimeters.

Answers

Answer:

[tex]10cm^2[/tex]

Step-by-step explanation:

We are given that

Two parallel sides of trapezoid are

[tex]a=1\frac{1}{2}cm=\frac{3}{2}=1.5cm[/tex]

[tex]b=3\frac{1}{2}=3+0.5=3.5 cm[/tex]

Height of trapezoid, h=4 cm

We have to find the area of the trapezoid.

We know that

Area of trapezoid=[tex]\frac{1}{2}(a+b)h[/tex]

Where a and b are two parallel sides

h=Height of trapezoid

Using the formula

Area of trapezoid=[tex]\frac{1}{2}(1.5+3.5)\times 2[/tex]

In ΔDEF, d = 6.4 inches, e = 7.8 inches and ∠F=33°. Find the length of f, to the nearest 10th of an inch.

Answers

9514 1404 393

Answer:

4.3 in

Step-by-step explanation:

The Law of Cosines is applicable when you have two sides and the angle between them. The third side satisfies ...

f² = d² + e² -2de·cos(F)

f² = 6.4² + 7.8² -2·6.4·7.8·cos(33°) ≈ 18.0671

f ≈ √18.0671 ≈ 4.2505

The length of f is about 4.3 inches.

THE ANSWER IS: y = -x+9

y=mx+b
m=slope=(y2-y1)/(x2-x1)
use the points (0,9) and (9,0)
(0-9)/(9-0) = -9/9 = -1
so m=-1

b is the y-intercept which is where x=0
the line crosses the y axis at y=9
so b=9

plugging in m and b into y=mx+b,
you get y=-x+9

Using The graph below identify the axis of symmetry for the parabola below

Answers

Answer:

x=-3

Step-by-step explanation:

The axis of symmetry is the line that separates a parabola directly in half. It is measure on x axis because it is being split in terms of that number. Next, you identify the origin and find exactly where the parabola is in half and that is your answer. Another way to do this would be to identify the vertex of the parabola. The answer is the x coordinate of the location of the vertex. (The highest point of a parabola.)
