Answer:

C

Step-by-step explanation:

To simplify this equation,

-x+10<2

-10 from both sides

-x<-8

Take out the negative

x<8

This means x is less than 8

For ≤ and ≥ , use a closed dot to indicate the number itself is part of the solution.

For < and >, use an open circle to indicate the number itself is not part of the solution.

In this case you use a open circle and becasue x is less than 8, the arrow pointing left is correct.

Answer:

d. 2

Step-by-step explanation:

a mode is the most frequently appeared value in a set of data. in other words, the most repeated number in a set of x, y, z.

example:

2, 3, 8, 7, 8, 7, 8

number of times 2 appeared: 1

number of times 3 appeared: 1

number of times 7 appeared: 2

number of times 8 appeared: 3

the mode here would be 8, since it is the most repeated number.

I hope this helped.

Answer: 187.96 cm

Step-by-step explanation: First you need to convert all of the units into centimeters. To do this you need to convert the 6 feet into inches. Since there are 12 inches in a foot, 6 feet is equal to 72 inches. Next add the 2 inches to 72, and now this means Tyson is 74 inches tall. Lastly convert the inches into centimeters by multiplying 74 by 2.54, which equals 187.96.

Answer:

187.96cm

Step-by-step explanation:

Step 1: Convert 6 feet 2 inches to centimeters.

We have 1 inch = 2.54 cm and 1 foot = 12 inches and 1 feet = 30.48 cm

=> 6 feet 2 inches is about 187.96cm

The ladder has 39.6 feet

Step-by-step explanation:

Length Units Conversion

To convert from meters to feet we use the relation

1 m = 3.3 ft

The ladder that Nicholas needs to repair the roof of his grandmother's hours is 12 meter long.  

Converting this length to feet we have

12 * 3.3 = 39.6 ft

The ladder has 39.6 feet

Answer:

72.66 calories

Step-by-step explanation:

1. find 1g of bannana = calories

86÷100g = 0.86 calories

1g of bannana = 0.86 calories

2 find 1g of yougurt = calories

89÷100g = 0.89 calories

1g of yougurt = 0.89 calories

3. 70g of bannana= 70×0.86

= 60.2 calories

4. 14g yogurt= 14×0.89

= 12.46 calories

5. 60.2 calories +12.46 calories = 72.66 calories

Answer:

y = ⅗x

Step-by-step explanation:

The line passes through the point of origin, (0, 0). This implies that the graph represents a proportional relationship between x and y. Thus, in slope-intercept form, the line of a proportional graph can be represented as y = mx.

Where,

m = slope/constant of proportionality = y/x

To write an equation for the line, let's find the slope using any of the points on the line.

Using (50, 30):

Slope (m) = 30/50 = ⅗

Plug in the value of m into y = mx

Thus, equation of the line would be:

y = ⅗x

Step-by-step explanation:

The height of the cone is 8 feet by using the Pythagorean theorem.

The height of a cone can be found using the Pythagorean theorem and the slant height and radius (or diameter) of the base.

Given that the slant height of the cone is 17 feet and the diameter of the base is 30 feet, we can use the following formula to find the height:

height = √(slant height² - (diameter/2)²)

So in this case, the height of the cone would be:

height = √(17² - (30/2)²) = √(289 - 225) = √(64) = 8

Thus, the height of the cone is 8 feet.

Answer:

SSS similarity.

Step-by-step explanation:

AA, SAS, and SSA similarities means the triangle must have an angle, which it doesn't, so by process of elimination it is SSS similarity.

By AA similarity criteria, the triangle AOB is similar to the triangle COD. Therefore, option A is the correct answer.

In the given figure, two lines AB and CD are parallel.

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

Consider, the triangle AOB and the triangle COD.

Here, AB║CD

∠BAO=∠CDO (Alternate interior angles)

∠ABO=∠DCO (Alternate interior angles)

By AA similarity criteria ΔAOB≈ΔCOD

By AA similarity criteria, the triangle AOB is similar to the triangle COD. Therefore, option A is the correct answer.

Answer: Add 5 to both sides

What is the first step needed to solve 4 over 7 the whole multiplied by x minus 5 equal negative 13?

Answer- Add 5 to both sides

(4/7)x - 5 = -13

• As mentioned above, first step would be,

adding 5 to both sides

=> (4/7)x - 5 + 5 = -13 + 5

=> (4/7)x = -8

• Now, transporting 7 from L.H.S. to R.H.S

=> 4x = -8 × 7

=> 4x = -56

• Now in the same way, transporting 4 from L.H.S. to R.H.S

=> x = (-56/4)

=> x = -14

• And in this way, or taking (Add 5 to both sides) as our first step, we find that the value of x is -14.

∴ x = -14

Answer:

x = 10, y = 7.5

Step-by-step explanation:

Given the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{AE}{AC}[/tex] = [tex]\frac{DE}{BC}[/tex], substitute values

[tex]\frac{x}{4}[/tex] = [tex]\frac{12.5}{5}[/tex] ( cross- multiply )

5x = 50 ( divide both sides by 5 )

x = 10

and

[tex]\frac{AD}{AB}[/tex] = [tex]\frac{DE}{BC}[/tex] , that is

[tex]\frac{y}{3}[/tex] = [tex]\frac{12.5}{5}[/tex] ( cross- multiply )

5y = 37.5 ( divide both sides by 5 )

y = 7.5

Answer:

OC. 5x + 45 + 7y + 14 - X, OE. 4x + 7y + 11

Step-by-step explanation:

Because, 5(x + 9) is 5x + 45 and 7(y + 2) is 7y + 14 and so you simplify by simplifying the like terms for example 5x - x = 4x 45 + 14 = 59 and 7y stays the same.

The expression 5(x + 9) + 7(y + 2) - x can be equivalent to 4x + 7y + 59 and 5x + 45 + 7y + 14 - x, so option B and C are correct.

A mathematical expression is made up of a statement, at least two integers or variables, and one or more arithmetic operations.

Given expression:

5(x + 9) + 7(y + 2) - x

If you simplify, you will get,

5x + 45 + 7y + 14 - x,

And as further simplified we get,

4x + 7y + 59

Therefore, the expression 5(x + 9) + 7(y + 2) - x can be equivalent to 4x + 7y + 59 and 5x + 45 + 7y + 14 - x.
