The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answers
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143
The pharmacist has a 2.8 L bottle of cough syrup. If she fills a bottle that is 1,200 ml, how many ml of cough syrup does the pharmacist have left?
160 ml
400 ml
1,600 ml
4,000 ml
Answers
Answer: 1,600 ml
Step-by-step explanation:
You can arrive at this answer by subtracting the amount of cough syrup used (1,200 ml) from the initial amount in the bottle (2.8 L, which is 2,800 ml).
2,800 ml - 1,200 ml = 1,600 ml
I hope this helps :)
Answer: 1,600 mL
Step-by-step explanation:
1. convert the 1,200 mL to L, which is 1.2 L.
2. Subtract that value from 2.8 L, equaling 1.6 L
3. Convert the 1.6 L back into mL by multiplying by 1000, which is equivalent to 1600 mL.

Answer:
Maybe congruent
Step-by-step explanation:
You have two isosceles triangles, one with a marked base angle of 49° and the other marked with an a.pex angle of 82°. One side of one triangle is marked as 11 cm.
CongruenceIn order for the triangles to be congruent, corresponding angles must be congruent, and corresponding sides must be congruent.
AnglesEach isosceles triangle has two congruent base angles and an a.pex angle that total 180°. The base angles in the triangle on the right are ...
2x +82° = 180°
2x = 98°
x = 49° . . . . . . congruent with the base angles of the other triangle
Corresponding angles of the triangles are congruent, so the triangles are similar.
SidesOnly one side in the diagram is marked, so we cannot make any claim regarding the measures of corresponding sides in the two triangles. If corresponding sides are congruent in the similar triangles, then the triangles will be congruent.
We can only conclude that the triangles may be congruent.

A composite figure is shown.
A five-sided figure with two parallel sides. The shorter one is 16 feet. The height of the figure is 22 feet. The portion from the vertex to the perpendicular height is 6 feet. The portion from a point to a vertical line created by two vertices is 6 feet.
Which of the following represents the total area of the figure?
968 ft2
616 ft2
484 ft2
352 ft2
Answers
Option (C) 484 ft²
Step-by-step explanation:The Five Sided figure can be divided into 2 Triangles and 1 Rectangle.
The Dimensions of the Triangle that is on the Left are as follows:Length of the triangle = 22 Feet
Breadth of the triangle = 8 Feet
Area of the triangle = (Length * Breadth) / 2
= (22 * 8) / 2
= 176/2
= 88 ft²
The Dimensions of the Triangle that is on the Right are as follows:Length of the triangle = 22 Feet
Breadth of the triangle = 4 Feet
Area of the triangle = (Length * Breadth) / 2
= (22 * 4) / 2
= 88/2
= 44 ft²
The Dimensions of the Rectangle are as follows:Length of the rectangle = 22 Feet
Breadth of the rectangle = 16 Feet
Area of the triangle = (Length * Breadth)
= (22 * 16)
= 352 ft²
The Total Area of the Five Sided figure can be found by summing up the areas of the Triangles and the Rectangle.
The Total Area of the figure is 88 + 44 + 352 = 484 ft²
So, the total area of the figure is 484 ft².

The area of the trapezoid is 308 ft2, the correct option is D.
We are given that;
Shorter side= 16 feet
b2=6+6=12 ft
Height= 22 feet
Now,
To find the area of a trapezoid, you need to know the lengths of the two parallel sides (the bases) and the height. The formula for the area of a trapezoid is:
A=21(b1+b2)h
where b1 and b2 are the lengths of the bases and h is the height1.
Substitute these values into the formula and simplify:
A=21(16+12)×22
A=21×28×22
A=14×22
A=352
Therefore, by the area the answer will be 308 ft2.

10 tolas gold bought from American market at $ 553 per tola is sold in Nepal at 20% customs duty charge and 13% VAT. At what price should it be sold ?
Answers
Answer: $735.49
Step-by-step explanation:
Given, the price of 10 tolas gold bought from American market = $553
Custom duty charge = 20%
VAT = 13%
Custom duty charge = 20% of $553
= 0.20 x 553 [we divide a perecntage to convet it into decimal]
= $110.6
VAT = 13% of $553
= 0.13 x 553
= $71.89
Selling price = Original price +Custom duty charge + VAT
= $553+$110.6+ $71.89
= $735.49
Hence, it should be sold at $735.49 .

Answers
Answer:
The slope is 2.5 and that means that 2.5 millimeters of rain falls every hour.
Explanation:
We can clearly see that the graph is moving in a positive direction, so we know our slope will be positive. Using the rise over run technique, we will have to rise 5 and move right 2 units in order to get from the first point to the second point. 5/2 = 2.5
So every hour, 2.5 mm of rain falls.

Which of the following explains the student's error?
Multiple choice questions.
cross out
A)
The two angles must equal 90°, so 2x+6+60=90
C)
The two angles do not equal 180°. They are vertical angles, so 2x+6=60
D)
The student should have added 66 to both sides of the equation instead of subtracting 66.
Part B
Fill in the blank question.
What is the correct solution?
Answers
The correct explanation for the student's error is: (C) The two angles do not equal 180°. They are vertical angles, so 2x+6=60
Vertical angles are pairs of angles formed when two lines intersect. These angles are opposite each other and have equal measures. However, the student incorrectly assumed that the vertical angles were supplementary angles (adding up to 180°).
As a result, they set up the equation as 2x + 6 + 60 = 180, which does not apply to vertical angles. This is why option C explains the error by stating that the two angles are vertical angles, and the correct equation should be 2x + 6 = 60.
To solve the correct equation for 'x', which is 2x + 6 = 60, follow these steps:
Start with the equation: 2x + 6 = 60Subtract six from both sides of the equation: 2x = 54Divide both sides by 2: x = 27The correct solution is x = 27, which means that the value of 'x' that satisfies the equation 2x + 6 = 60 is 27. This correctly reflects the measure of the angle within the given context.
In summary, the student's error stemmed from misunderstanding the nature of vertical angles and incorrectly assuming that they were supplementary angles. By recognizing the correct characteristics of vertical angles and applying the appropriate equation, the solution can be accurately determined as x = 27.

whats the surface area?
Answers
Answer:
1108 in²
Step-by-step explanation:
You want the total surface area of the pentagonal prism shown.
Base areaThe area of each of the two pentagonal bases is the sum of the area of the yellow rectangle and the area of the triangle above it. That sum is ...
A = LW +1/2bh
A = 5(12) +1/2(12)(9) = 12(5 +9/2) = 114 . . . . square inches
Lateral areaThe lateral area of the prism is the sum of the areas of the 5 rectangles. That sum will be the product of the perimeter of the pentagonal base and the distance between bases.
LA = (12 +5 +11 +11 +5)(20) = (44)(20) = 880 . . . . square inches
Total areaThe total surface area of the figure is the sum of the two base areas and the lateral area:
SA = 2(114 in²) +880 in² = 1108 in²
The surface area of the composite figure is 1108 in².
