In Albany it is -4F, in Chicago it is -14F, in Minneapolis it is -11F, and in Toronto it is -13F. In which city is it the coldest?
Answer:
Chicago
Step-by-step explanation:
Compare the temperatures:
-4, -14, -11, -13
Numbers become smaller to the left on the number scale.
For instance, -10 is less than -5.
So, -13, -11, and -4 are all greater than -14.
And the lower the temperature, the colder it is.
Thus, Chicago is the coldest.
A long distance phone call costs $1.75 plus $0.30 for each minute of the coll. Write and solve a
linear equation to find the length of a phone call that cost $7.45.
Answer:
1.75 + 0.3x = 7.45; 19 minutes
Step-by-step explanation:
The cost of the phone call is found by 1.75 + 0.30 multiplied by the number of minutes the calls lasts. The cost of the call is 7.45 so 1.75 + 0.3x = 7.45. Begin by subtracting 1.75 from each side of the equation. That leaves 0.3x = 5.7. Then divide both sides by 0.3. This gives x = 19.
Find the measures of the angles formed by (a) two consecutive radii and (b) a radius and a side of a equilateral triangle?
Answer:
(B)45°, 67.5°
Step-by-step explanation:
A regular polygon is a polygon in which all the sides are equal.
An Octagon is a polygon with 8 sides.
Since it is a Regular polygon, the following holds:
1.The Radii are equal
2. The angle Subtended by two radii are equal for all triangles in the octagon.
3. There are 8 Isosceles triangles in the octagon.
(a)Measures of angle formed by Two radii
From the centre of the octagon, there are 8 equal angles.
Sum of Angle at a point= 360°
Each Angle=360°÷ 8 = 45°
The measures of angle formed by two radii is 45°.
(b)a radius and a side of the polygon.
Since the triangles are Isosceles, the base angles at the side of the octagon are equal.
Let x be the angle made by a radius with a side.
From (a) above,
x+x+45°=180°(Sum of Angle in a Triangle)
2x=180-45°
2x=135°
x=135°÷2=67.5°
The angle between a radius and a side of the polygon is 67.5°.

Henry wraps a gift box in the shape of a square pyramid. The figure below shows a net for the gift box.
The amount of wrapping paper needed for the square pyramid gift box is: 96.72 in.².
What is the Surface Area of a Square Pyramid?Surface area of a square pyramid = area of the square base + area of the 4 triangular faces = s² + 4(1/2bh).
We are asked to find the amount of wrapping paper that would be needed to wrap the gift box, which is the surface area of the gift box that has a square pyramid shape.
Given the following dimensions of the gift box:
s = 5.2 in.
b = 5.2 in.
h = 6.7 in.
Plug in the values into s² + 4(1/2bh):
Surface area of a square pyramid = 5.2² + 4(1/2 × 5.2 × 6.7).
Surface area of a square pyramid = 96.72 in.²
Therefore, the amount of wrapping paper needed for the square pyramid gift box is: 96.72 in.².

The perimeter of a regular nonagon is 45 m. How long is each side?
Answer:
5 m
Step-by-step explanation:
A nonagon has 9 sides. You get individual side length by dividing the perimeter by amount of sides. 45 divided by 9 is 5.
Re-write the equation 6x + 3y = 30 in slope-intercept form y=mx+b.
Slope=2
x−intercept= 2/10 =5
y−intercept= −10/-1 =−10.00000
Answer:
2x+y-10=0
Step-by-step explanation:
6x+3y=30 move the constant to the left and change its sign
6x+3y-30=0
6x+3y-30=0 divide both sides of the equation by 3
what is the simplest form of 28/91?
Answer:
4/13
Step-by-step explanation:
We can first find the GCD or GCF of 28 and 91. 91 in its simplest form is 13*7. 28 in its simplest form is 2*2*7. The only common factor they have is 7, so 7 is the GCD. We can divide both by 7 to get [tex]\frac{4}{13}[/tex]

Line parallel to y=0.5x+3 that passes through the point (−9,12)
Complete question is;
Write the equation of line in slope-intercept form. Line parallel to y = 0.5x + 3 that passes through the point (−9,12)
Answer:
y - 12 = 0.5(x + 9)
Step-by-step explanation:
We want to find the line parallel to y = 0.5x + 3 that passes through the point (−9,12).
To some this, we will use the equation;
y - y1 = m(x - x1)
Here, x1 = -9, y1 = 12, m = 0.5
Thus;
y - 12 = 0.5(x - (-9))
y - 12 = 0.5(x + 9)

(3h+7k)2
Answer:
6h+14k
Step-by-step explanation:
Multiply 2by 3h which gives 6h then multiply 7k by 2 which gives 14k.
Since 6h and 14k are not like terms u cannot add so your answer will be 6h + 14k.
Answer:
9h² + 42hk + 49k²
Step-by-step explanation:
Given
(3h + 7k)²
= (3h + 7k)(3h + 7k)
Each term in the second factor is multiplied by each term in the first factor, that is
3h(3h + 7k) + 7k(3h + 7k) ← distribute both parenthesis
= 9h² + 21hk + 21hk + 49k² ← collect like terms
= 9h² + 42hk + 49k²

3. 3x = 12
An open statement in math means that it utilizes variables, and can only be concluded as being "true" or "false". The problem would result in asking whether or not it is always true or not. In this case, x will be true when you plug in 4, however, it will not be true when you plug in any other number. Therefore, it is a closed statement that can be falsified.
4. Open.
The statement can be true if the variable g is 35, however, it is false if it is not. An open statement concludes that it may or may not be correct, thereby being open.

If x = –12 and y = 16, evaluate x + y – 5x.
Answer:
64
Step-by-step explanation:
- 12 + 16 - 5 (-12)
- 12 + 16 + 60
4 + 60
= 64
Answer:
64
Step-by-step explanation:
If x = –12 and y = 16, evaluate x + y – 5x.
Solution,
= x + y - 5x
= -12 + 16 - 5 ( -12 )
= - 12 + 16 + 60
= - 12 + 76
= 64
Ray's favorite activity is taking a leisurely bike ride through the park after work. If he 326 burns calories every hour, how many hours does he need to ride in order to burn off an extra doughnut and large frozen latte that he ate that afternoon? The doughnut had 320 approximately calories, and the latte had 820 calories.
Answer: 3.5 hours
Step-by-step explanation:
From the question, we are informed that Ray's burns 326 calories every hour. We are further told that he ate a doughnut that had 320 calories, and a latte had 820 calories. The total calories will be:
= 320 + 820
= 1140 calories
The number of hours needed to burn the calories will be the total calories divided by the amount of calories burnt in an hour. This will be:
= 1140/326
= 3.5 hours
