Answer:

A. -0.8

Step-by-step explanation:

non of the other answers will work because they are positive.

Answer:

A, y = -0.8

Step-by-step explanation:

To solve this, you have leave the y alone.

Subtract 4.2 from both sides.

y + 4.2 - 4.2 = 3.4 - 4.2

y = 3.4 - 4.2

y = -0.8

Step-by-step explanation:

9/3=3

cost of 1 drink=3 dollars

5x3=15

Answer is 15

Answer:

28, 44, 22

Step-by-step explanation:

a+b+c = 94

2×c = b

a = c+6

=>

c+6 + 2×c + c = 94

4×c + 6 = 94

4×c = 88

c = 22

=>

b = 2×22 = 44

a = 22 + 6 = 28

=========================================================

Explanation:

The sides are in the ratio 4:7:10

This scales up to 4x:7x:10x showing that the sides are 4x, 7x and 10x. The variable x is some positive real number.

Add up the sides and set this equal to the given perimeter 105. Solve for x.

4x+7x+10x = 105

21x = 105

x = 105/21

x = 5

This value is then plugged into each side

The triangle has sides of 20 cm, 35 cm, and 50 cm.

Note how the ratio 20:35:50 reduces to 4:7:10 after dividing all three parts by the GCF 5. Also, we can see that 20+35+50 = 105 to fully confirm our answer.

Answer:

3x!

Step-by-step explanation:

Since the sides are the same (marked with the lines on the side) the 2 angles are also the same! :D

Answer:

r ≈ 7.9 inches

Step-by-step explanation:

V(cylinder) = πr²h

196 = πr²(1)

196/π = r²

62.4 = r²

√62.4 = r

r ≈ 7.9

Answer: 9

Answer:

B) y=0

Step-by-step explanation:

The exponential function shown has a horizontal asymptote at the line y=0, which means that y will approach 0 as the value of x decreases. Therefore, B is correct.

Answer:

no real answer

Step-by-step explanation:

distribute the -4 and combine all of the like terms on the left side = r-8-4r, then -8-3r

then we have 7-3r=-8-3r

from here, we can already tell that there's no real answer. this is because the two -3r will cancel, leaving no variable.

since 7 doesn't equal -8, there is no answer.

if, for example, the value on both sides of the equal sign were the same after the variable was eliminated, then your answer would be all real numbers

The distance between two points:

[tex] \large \boxed{ \sqrt{(x_2 - x_1)^{2} + {(y_2 - y_1)}^{2} } }[/tex]

From the graph, the given points are (-3,1) and (5,-4). Substitute the points in as we get:

[tex] \large{d = \sqrt{ {( - 3 - 5)}^{2} + {(1 + 4)}^{2} } } \\ \large{d = \sqrt{ { (- 8)}^{2} + {5}^{2} } } \\ \large{d = \sqrt{64 + 25} \longrightarrow \sqrt{89} } [/tex]

Hence the distance between two points is √89.

Answer:

n = 3/5

Step-by-step explanation:

Represent this quotient as:

   n

---------

-2/3

and set it equal to -9/10:

   n           -9

--------- = -------

-2/3          10

Cross multiplication yields:

10n = 6, so that n = 6/10 or n = 3/5

Answer:

Triangle c

Step-by-step explanation:

First is Isosceles as the two sides are the same. The second is also isosceles and the fourth does not make a right angle.

Answer:

A

Step-by-step explanation:

the given equation can be simplified to 12m+17

so if we simply the other options we see that A = 13m+17

Answer:

(h/g)(x) = x² - 2x

Step-by-step explanation:

h(x) = x³ - 4x

g(x) = x + 2

(h/g)(x) = h(x)/g(x) = (x³ - 4x) / (x + 2) = x² - 2x

Answer:

In a pyramid, line segment AD is the perpendicular bisector of triangle ABC on line segment BC. If AB = 20 feet and BD= 7 feet, find the length of side AC.

Step-by-step explanation:

Solution

It is given that AD is the perpendicular bisector on the line segment BC.

So, By Perpendicular Bisector Theorem, any point on line segment AD is at an equal distance from points B and C. It implies, AB = AC

AC = 20 feet.

Answer:

a= 4. b=19. n=4. d= b-a/n+1= (19-4)/(4+1)= 15/5=3. Hence, d=3.

Answer:

7  10  13   16

Step-by-step explanation:

a1 = 4

a6 = 19

n = 6

d = ?

a6  = a1 + (n - 1)d        

19 = 4 + (6 - 1)*d

19 - 4 = 5*d

15 = 5d

d = 15/5

d = 3

So the sequence is

4,7,10,13,16,19

Answer:

positive

Step-by-step explanation:

Step-by-step explanation:

Given:

In the given cone,

Radius of the cone = 7.2 m

Slant height of the cone = 17 m

To find:

The surface area of the cone.

Solution:

The surface area of a cone is:

[tex]A=\pi rl+\pi r^2[/tex]

Where, r is the radius of the cone and l is the slant height of the cone.

Putting [tex]\pi=3.14,\ r=7.2,\ l=17[/tex] in the above formula, we get

[tex]A=(3.14)(7.2)(17)+(3.14)(7.2)^2[/tex]

[tex]A=384.336+162.7776[/tex]

[tex]A=547.1136[/tex]

[tex]A\approx 547.11[/tex]

Therefore, the surface area of the given cone is 547.11 square m.

Answer:

every parallelogram is a square? False

every rectangle with four congruent sides is a square? True

every rectangle is a quadrilateral? True

every quadrilateral is a rectangle?​ False

Step-by-step explanation:

every parallelogram is a square?

A parallelogram has two opposite pairs of parallel lines and opposite congruent sides. A square needs to have 4 right angles and all sides need to be equal. In the restrictions of a parallelogram, these cannot be concluded, therefore parallelogram are not always squares.

every rectangle with four congruent sides is a square?

Square require 4 congruent sides and 4 right angles. Rectangles already have  4 right angles. If you add 4 congruent sides to the mix, it means that these rectangles are always squares.

every rectangle is a quadrilateral?

A quadrilateral is defined by a shape having 4 sides. Rectangles have 4 sides, so they fit into the category of quadrilaterals.

every quadrilateral is a rectangle?​

A quadrilateral is a just a shape with four sides. We do not know if it has 4 right angles, so not every quadrilateral is a rectangle.
