The value of surface area of the right cone is,
⇒ 175.8 units²
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Radius of cone = 4 units
Slant height = 10 units
Now, The formula for the total surface area of a right cone is,
T. S. A = πrl + πr²
Hence, We get;
The value of surface area of the right cone is,
⇒ 3.14 x 4 x 10 + 3.14 x 4²
⇒ 125.6 + 50.24
⇒ 175.8 units²
Thus, The value of surface area of the right cone is,
⇒ 175.8 units²

The equation of the line that passes through the point (1,5) and is parallel to the linex + 3y =6
Answers
Answer:
Y=3x+2
Step-by-step explanation:
first you have to put it in the formula y = mx + c
Y=3-x
in this format c = 0 so there's no intercept
Y=3x+c
The parallel line will have the same gradient but different intercept.
Now we substitute the coordinates(1,5) into the formula.
y = 5
x = 1
5=(3*1)+c
5=3+c
Now we make c the subject.
c=2
So the answer is:Y=3x+2

Deondra has $420 to spend at a bicycle store for some new gear and biking
outfits. Assume all prices listed include tax.
• She buys a new bicycle for $236.31.
She buys 2 bicycle reflectors for $3.07 each and a pair of bike gloves for
$34.75.
• She plans to spend some or all of the money she has left to buy new biking
outfits for $59.50 each.
Write and solve an inequality which can be used to determine o, the number
of outfits Deondra can purchase while staying within her budget.
Answers
Answer:
Deondra can buy 2 outfits.
Step-by-step explanation:
Since Deondra has $ 420 to spend at a bicycle store for some new gear and biking outfits, and she buys a new bicycle for $ 236.31, 2 bicycle reflectors for $ 3.07 each and a pair of bike gloves for $ 34.75, and she plans to spend some or all of the money she has left to buy new biking outfits for $ 59.50 each, to determine the number of outfits Deondra can purchase while staying within her budget the following calculation must be performed:
(420 - (236.31 + 2 x 3.07 + 34.75)) / 59.5 = X
(420 - (236.31 + 6.14 + 34.75)) / 59.5 = X
(420 - 277.2) / 59.5 = X
142.8 / 59.5 = X
2.4 = X
Therefore, Deondra can buy 2 outfits.

Answers
(3,4) and (6,2) could be vertices of a right triangle with (6,4) and (3,2)
(0,0) is on the same line as (6,4) and (3,2) so it doesn't even form a triangle, much less a right triangle.
(3,6) forms a scalene isosceles triangle, but not a right triangle It's a 4-sqr13-sqr13 triangle
(4.5,3) also forms an obtuse isosceles triangle, but not a right triangle It's a sqr13 - sqr3.25 - sqr3.25 triangle

A=1/2 bh; solve for b
I need help anyone help me with this
Answers
Answer:
b=2A/h
Step-by-step explanation:
[tex]A = \frac{1}{2} bh \\ \\ \therefore \: 2 A = bh \\ \\ \therefore \: b = \frac{2 A}{h} [/tex]
Answer:
b = 2A/h
Step-by-step explanation:
To isolate b, you should first "get rid" of the 1/2. The best way to do this to multiply both sides of the equation by 2. The left side becomes 2A, while the right becomes bh (1/2 multiplied by its reciprocal, 2, becomes 1). Next, you have to move the h to the left side, and you could do so by dividing both sides by h. The left side becomes 2A/h, and the right is just b by itself, getting you b = 2A/h.

The dimensions (width and length) of room1 have been read into two variables : width1 and length1 . The dimensions of room2 have been read into two other variables : width2 and length2 . Write a single expression whose value is the total area of the two rooms. (width1length1) (width2length2)
Answers
Answer:
Total area of the two rooms = (width1length1) + (width2length2)
Step-by-step explanation:
The area of the rectangular shape is given by = Length * breadth
Therefore the area of the two rooms can be calculated using the above formula when the variables lengths and widths are given.
Area 1= Area of the first room = length * breadth= (width1length1)
Area 2=Area of the second room = length * breadth= (width2length2)
Total area of the two rooms = Area1 + Area 2
= (width1length1) + (width2length2)

Step-by-step explanation:
Angles 1 and 3 are "corresponding" angles, so are congruent.
∠1 = ∠3
20x +60 = 30x +20
40 = 10x . . . . . . . . . . . . subtract 20x+20
4 = x . . . . . . . . . . . . . . divide by 10
∠1 = 20x +60 = 20(4) +60 = 80 +60
∠1 = 140°
Answer:
140°
Step-by-step explanation:
Angle 1 and angle 3 are corresponding angles ;
Corresponding angles are equal ;
Hence,
Angle 1 = Angle 3
20x + 60 = 30x + 20
Collect like terms
20x - 30x = 20 - 60
-10x = - 40
x = 4
Angle 1 is thus :
20x + 60 ; x = 4
20(4) + 60
80 + 60
= 140°

Answer:
a) The equation (10s + 8w) represents the calories Bridget ate on Monday and the equation (20s + w) represents the calories she ate the next day.
b) The number of calories in each strawberry is 4 and the number of calories in each vanilla wafer cookie is 19. The solution is s= 4 and w = 19.
Step-by-step explanation:
For part A, Bridget ate 10 strawberries and 8 vanilla wafer cookies on Monday. Since the the number of calories in a strawberry is s and the number of calories in a vanilla wafer cookie is w , the number of calories Bridget ate on Monday is 10s + 8w. The next day, Bridget ate 20 strawberries and 1 vanilla wafer cookie. Hence, the number of calories Bridget ate on the next day is 20s + w.
For part B,
we will create two different simultaneous equations.
Equation 1: 10s + 8w = 192
Equation 2: 20s + w = 99
We need to find one of the terms first to solve the other term. For this case, I will solve for w first.
Multiply the first equation by 2.
Equation 3: 20s + 16w = 192*2 = 384.
Now, subtract equation 2 from this new equation.
Equation 4:
(20s + 16w) - (20s + w) = 384 - 99
20s + 16w - 20s - w = 285
15w = 285
This leaves only w left and we can solve w.
w = 285 / 15 = 19
Now, we can solve for s using equation 2.
20s + 19 = 99
20s = 99-19 = 80
Hence,
s = 80/20 = 4

This question did provide some clues to answer this question. Every week, the area covered by the algae is multiplied by 2^1.
To find the area cover increase by the algae per day, the exponent should be divided by 7 since there are 7 days in a week. Hence, every day, the area covered by the algae multiplies by 2^(1/7). In other words, 1 day after the algae was spotted, the area is 12.5 * 2^(1/7), which answers part B.
10 days after the algae was spotted, the area covered by the algae is 12.5 * 2^[(1/7)*10] = 33.6475... , which rounds up to 34 and answers part A.
