x divided by 6 - 11 = -10

Answers

Answer:

x = 50

Step-by-step explanation:

[tex]\frac{x}{6-11} =-10\\\\\frac{x}{-5} =-10\\Cross-Multiply\\x = - 10\times -5\\x = 50[/tex]

Equation:

x/6 - 11 = -10

Add 11 to both sides

x/6 = 1

Multiply both sides by 6

x = 6

Compare the probability that an adult has side effects with the probability
that a child has side effects. Draw a conclusion based on your results.

Answers

Answer:

Step-by-step explanation:

The given information is expressed as

Side effect no side effect total

Adult 7 43 50

Children 22 28 50

Total 29 71 100

Probability is expressed as

Number of favorable outcomes/number of total outcomes

For the probability that an adult has side effects,

Total number of outcomes = 50

Number of favorable outcomes = 7

Probability that an adult has side effects = 7/50 = 0.14

For the probability that a child has side effects,

Total number of outcomes = 50

Number of favorable outcomes = 22

Probability that an adult has side effects = 22/50 = 0.44

Therefore, it is more likely that a child has side effects compared to an adult

What is the product of (x-5) and (x-4)? Use the model to find the result

Answers

Answer:

The product of the model  is [tex]x^2-9x+25[/tex]

Step-by-step explanation:

Given the expression  (x-5) and (x-4)

The product of the two factors can be expressed as follows

[tex]= (x-5) (x-4)\\=x(x-4)-5(x-5)\\[/tex]

Opening brackets we have

Answers

Answer:

x = 136

Step-by-step explanation:

A quadrilateral always has angles that sum to 360.  Thus, 47 + 95 + 82 + x = 360.  Subtract 47, 95, and 82 from each side and get x = 136.

Tell whether each of the following is a function.
7. Which of the following could be a function? Select three that apply.
I A {(-2,-4), (-1,-2), (0, 0)}
B {(1,-2), (1, -3), (1,-4)}
C {(-2, 1), (-3, 1), (-4,1)}
D {(-1,3), (7,3), (5, -7)}
E {(6,-1),(4,3), (6,-8)}

Answers

Options A, C and D are functions.

In a function, for every number for 'x' there is only one 'y'. So, if you have two ordered pairs in a choice that have the same number for 'x', that is not a function.

Remember an ordered pair is written (x, y).

B is not a function as:
(x, y)
(1, -2)
(1, -3)
(1, -4)
^ All of the x-coordinates are the same.

E is not a function as:
(x, y)
(6, -1)
(6, -8)
^ Two of the x-coordinates are the same.

Thus, A, C and D are functions.

Answers

Answer:

q= 5

Step-by-step explanation:

Geometric mean of two term p and q is = [tex]\sqrt{pq}[/tex]

we have

p = √7​

geometric mean = √35

Thus, using the formula of geometric mean

√35 = √7​*q

[tex]\sqrt{35} = \sqrt{7q} \\[/tex]

squaring both sides

[tex]\sqrt{35}^2 = \sqrt{7q} ^2\\=>35 = 7q\\=> q = 35/7 = 5[/tex]

Answers

The correct answer is 48 mph


Explain

First, 32 miles

Average speed 64 mph

T1= time for first 32 miles

distance / speed

32 miles / 64 mph = 0.5 hrs


For remaining distance = 200 miles- 32 miles = 168miles


Let average speed = x


T1 = time for rest of journey = distance / speed

168miles / x mph

Since

Total time journey is 4 hours

T1 + t2 = 4hr


Or

0.5 +168/x = 4

168/x = 4-0.5

168/ x = 3.5

X= 168/ 3.5

X= 48 mph

Answer:

x=70

z=20

y=30

Step-by-step explanation:

first find x: the sum of straight angle is 180

x+110=180

x=180-110=70

now find z: the sum of the angles of triangle is 180:

x=70, right angle=90

z+70+90=180

find y:

y+110+40=180

y=180-150=30

z=180-160=20

Answer:

x=70 degrees, y= 30 degrees, z=20 degrees

Step-by-step explanation:

110+x=180 => straight angle def.

180-110+40=y => def. of angles in triangle

x( 70 degrees) +90+z=180, z= 20 => angles in triangle

If the ratio of the surface areas of two similar geometrical solids is given by 121:36, what is the
ratio of their volumes?

Answers

Answer:

1331:216

Step-by-step explanation:

Given the ratio of the lengths of two similar solids as a:b

The ratio of the surface areas = [tex]a^2:b^2[/tex]

The ratio of the volume = [tex]a^3:b^3[/tex]

We are given that the ratio of the surface areas of two similar geometrical solids is given by 121:36

Therefore:

[tex]a^2:b^2=121:36\\\implies a^2:b^2=11^2:6^2\\\implies a:b=11:6[/tex]

Since the ratio of the lengths is 11:6

The ratio of their volumes = [tex]11^3:6^3[/tex]

=1331:216

The ratio of the volume of the two similar geometrical solids is 1331:126.

Ms. Daffy tells you that the longest side of her right-triangular garden is 26m and one of the sides is 14m. A. She asks you to find the other side of the garden.

Answers

Answer:

22m

Step-by-step explanation:

The computation is shown below:

Since it is a right-triangular garden so we use the pythagoreus theorem

As we know that

The C^2 refers to the longest side of the right-triangular garden

So,

a^2 + b^2 = c^2

a^2 + 14^2 = 26^2

a^2 + 196 = 676

a^2 = 480

So a = 22m

Hence, the other side of the garden is 22m
