Answers
Complete question :
Mikel creates the table below to help her determine 40% of 70. She writes the expression Which change in Mikel’s expression will lead her to the correct answer?
Corresponding chart for the problem is attached below.
Answer:
The 0.2 in the expression could be changed to 2.
Step-by-step explanation:
40% of 70
Directly working this out, we obtain :
0.4 * 70 = 28
From the table :
To obtain same from the columns, 0.2 is adjusted to 2.
Hence, 2 * 14 = 28

Step-by-step explanation:
Here, we want to take all values of p up and all values of q down
From the division, 9
goes up and the term above comes down
We have all the following indices rule to use;
(a^x)^y = a^xy
a^x * a^y = a^x + y
a^x / a^y = a^x-y
Let us evaluate all p terms;
p^12/p^4 = p^8
Let us evaluate all q terms
q^16/q^10 * 1/q^2
= q^6/q^2 = q^4
Let us evaluate all number terms
We have;
2^4/-3^2 * 9/4^2
= 16/9 * 9/16 = 1
All
number terms canceled out
Now, let us work with the exponents;
For the p terms;
p^8 = p^a+b
a + b = 8 •••••••••(i)
For the q terms;
q^4 = q^a-b
a-b = 4 ••••••••••(ii)
Add both equations
2a = 12
a = 12/2 = 6
For b;
a-b = 4
6-b = 4
b = 6-4
b = 2

A 30 foot ladder is leaned against a wall, and the base of the ladder is 2 feet from the
base of the wall. What is the angle of inclination of the ladder? (Round to the nearest
whole degree)
Answers
explanation:
we can assume the ground makes a 90° angle with the wall. We can use primary trig ratios to determine the angle of inclination, which is between the ladder and the ground.
The hypotenuse is the length of the ladder, 30ft, and the adjacent side of our theta angle, (the angle we’re looking for) is 2ft.
Use the ratio Cosine and set up the equation
cosx = 2/30
cosx = 0.066667

The triangle is an isosceles triangle, which means that it has two equal sides and two equal angles.
Therefore, angles B and C are both equal to 75°.
A triangle measures 180°.
75 + 75 + x = 180
150 + x = 180
x = 30°
Angle A has to equal 30°.
(4y + 10)° = 30
4y + 10 - 10 = 30 - 10
4y = 20
y = 5

a fruit company delivers its fruit in two types of boxes : large and small. a delivery of 6 large boxes and 5 small boxes has a total weight of 145 kilograms. A delivery of 2 large boxes and 3 small boxes has a total weight of 57 kilograms. how much does each type of box weigh?
Answers
Answer:
Weight of large box = 18.75 kg
Weight of small box = 6.5 kg
Step-by-step explanation:
a fruit company delivers its fruit in two types of boxes : large and small. a delivery of 6 large boxes and 5 small boxes has a total weight of 145 kilograms. A delivery of 2 large boxes and 3 small boxes has a total weight of 57 kilograms. how much does each type of box weigh?
Let
Weight of large box = x
Weight of small box = y
6x + 5y = 145 (1)
2x + 3y = 57 (2)
Multiply (2) by 3
6x + 9y = 171 (3)
6x + 5y = 145 (1)
Subtract (1) from (3)
9y - 5y = 171 - 145
4y = 26
y = 6.5 kg
Substitute y = 6.5 kg into (2)
2x + 3y = 57
2x + 3(6.5) = 57
2x + 19.5 = 57
2x = 57 - 19.5
2x = 37.5
x = 37.5/2
x = 18.75 kg
Weight of large box = 18.75 kg
Weight of small box = 6.5 kg
A motorcycle tire with a radius of 16 inches rotates at a rate of 150 revolutions per minute (rpm).

Marla draws a diagonal in a rhombus to form two triangles. What term can she use to classify each triangle? Explain.
A.
Acute; a rhombus always has 2 acute angles so the 3 angles in each triangle must all be acute.
B.
Equilateral; since a rhombus always has 4 equal sides, each triangle must have 3 equal sides.
C.
Isosceles; since a rhombus always has 4 equal sides, each triangle must have 2 equal sides.
D.
Obtuse; a rhombus always has 2 obtuse angles so each triangle must have an obtuse angle.
Please answer ASAP
Answers
Answer: It's C because It was correct on my test.
If I wrong i'm really sorry
Step-by-step explanation:
C. Isosceles; since a rhombus always has 4 equal sides, each triangle must have 2 equal sides.
What is an Isosceles Triangle?An Isosceles Triangle is defined as a triangle with two sides of equal length is an isosceles triangle.
A rhombus is a quadrilateral with all four sides congruent, or equal in length. When a diagonal is drawn in a rhombus, it will always divide the rhombus into two congruent triangles. Since the opposite sides of a rhombus are congruent, the two triangles formed by the diagonal will always have two congruent sides. Therefore, each triangle is an isosceles triangle.
A rhombus can have angles of various degrees. It can have angles more than 90 degrees, less than 90 degrees, or 90 degrees which means the statements A, and D are incorrect.
B is incorrect because the triangles formed by the diagonal of a rhombus will not have 3 equal sides, because the diagonal will not be congruent with the sides.
Hence, the correct answer would be an option (C).
