Answer:

116

Step-by-step explanation:

we do pemdas so start with parenthesis

6+4=10

10 squared =100

then we divide before adding so

10/2 = 5+11= 16

100+16= 116

2.54,2,-1.79,-4

Step-by-step explanation:

gretest is 2.54 because 2.54 is nearer to 3so it is greatest. then 2 is smaller than 2.54 and then -1.74 and -4 because the number which is greater in negative is the most smallest number.

for , another example -1 is greater than-100.

Answer:

LOM= 130º

Step-by-step explanation:

Combine the two equations and set it to equal 180º(LON), 180º=12x+120º

next subtract 120º from both sides, 60º=12x. Now divide both sides by 12, 5=x. Now you can plug 5 back into the original equation to calculate MON, 8x5+90º

Answer:

∠MON = 130

Step-by-step explanation:

∠LON = 180°

∠LOM +  ∠MON = 180 -------equation

where:

∠LOM = 4x + 30

∠MON = 8x + 90

plugin values into the equation

4x + 30 + 8x + 90  = 180

4x + 8x + 30 + 90 = 180

12x = 180 - 30 - 90

12x = 60

x = 60/12

x = 5

plugin values to ∠MON = 8x + 90

∠MON =  8x + 90

∠MON = 8(5) + 90

∠MON = 130

Answer:

the new height of the triangle = 2.449

Step-by-step explanation:

Given that:

the sides of the triangle are 4m in length i.e they are equal. It shows that the triangle is known to be an equilateral triangle.

Let say the triangle is a triangle IJK

Let the length of the side to be i = 4

Definitely

IJ = JK = IK = i = 4

If a midline is drawn and cuts the equilateral triangle in two equal halves of a right-angle triangle. Then, suppose the midline is L

Then ;

[tex]JL = \dfrac{1}{2} JK[/tex]

[tex]JL = \dfrac{1}{2} i[/tex]

Let consider triangle IJL

(IL)² = (IJ)² - (JL)²

[tex](IL)^2 = i^2 - \dfrac{i^2}{4}[/tex]

[tex](IL)^2 = \dfrac{3i^2}{4}[/tex]

[tex](IL) =\sqrt{ \dfrac{3i^2}{4}}[/tex]

[tex]IL =\sqrt{3} \dfrac{i}{2}[/tex]

Area of triangle IJK can be expressed as:

[tex]Area = \dfrac{1}{2}\times Base \times Height[/tex]

[tex]Area = \dfrac{1}{2}\times i \times \sqrt{3}\dfrac{i}{2}[/tex]

[tex]Area = \sqrt{3}\dfrac{i^2}{4}[/tex]

where, i = 4

Then:

[tex]Area = \sqrt{3}\dfrac{4^2}{4}[/tex]

[tex]Area = \sqrt{3} \dfrac{16}{4}[/tex]

[tex]Area =4 \sqrt{3}[/tex]

when the area is exactly half of the original triangle's area, the new height is :

[tex]A = \dfrac{1}{2} \times Area[/tex]

[tex]\sqrt{3} \dfrac{i^2}{4} = \dfrac{1}{2} \times 4\sqrt{3}[/tex]

[tex]\dfrac{i^2}{4} = \dfrac{1}{2} \times 4[/tex]

[tex]\dfrac{i^2}{4} =2[/tex]

[tex]i^2 = 8[/tex]

[tex]i= \sqrt{8}[/tex]

[tex]i= \sqrt{4 \times 2}[/tex]

[tex]i= 2 \sqrt{2}[/tex]

Finally, the new height of the new triangle is:

[tex]IL =\sqrt{3} \dfrac{i}{2}[/tex]

[tex]IL =\sqrt{3} \dfrac{2 \sqrt{2}}{2}[/tex]

[tex]IL =\sqrt{3 \times 2}[/tex]

[tex]IL =\sqrt{6}[/tex]

IL = 2.449 m

Step-by-step explanation:

Answer:

g= −6/13o5

Step-by-step explanation:

Let's solve for g.

−3−(−8)−(−2)=x0−13ogo3o

Step 1: Flip the equation.

−13go5+1=7

Step 2: Add -1 to both sides.

−13go5+1+−1=7+−1

−13go5=6

Step 3: Divide both sides by -13o^5.

−13go5

−13o5

=6−13o5

g=−6/13o5

Answer:

first one is 2.2mm/year and second is 6.2years and -2.2mm/year

Step-by-step explanation:

plz trust me i just did it

The decimals in the problem should be represented as a negative rate is -2.2mm/year

It is defined as the change in values of a dependent variable with respect to the independent variables.

It is given that:

Ericka is also in Mr. Whittaker’s science class and she recorded the variation in water level at a different part of the river.

Ericka should first one is 2.2mm/year and the second is 6.2years and -2.2mm/year

Thus, the decimals in the problem should be represented as a negative rate is -2.2mm/year

Answer:

False

Step-by-step explanation:

The open circle means you should not include the number it is on.

The inequality would look like, x<2 and not equal to. Therefore, 2 is not a solution.

Answer:

False

Step-by-step explanation:

When there is an open circle, it means that it can't be that exact number. If there is a closed circle, it can be that number. This is an open circle, and means that it is less than 2.

Answer:

Parabolas always have a lowest point (or a highest point, if the parabola is upside-down). This point, where the parabola changes direction, is called the "vertex". If the quadratic is written in the form y = a(x – h)2 + k, then the vertex is the point (h, k).

Complete Question

A Chinese restaurant has the family special shown at right. What is the original average cost of the entrees if the discount is $2 per entree? ANY FOUR ENTREES FOR $20​

Answer:

$7

Step-by-step explanation:

From the question we are told that :

Any 4 entrees = $20,

And there is a discount of $2 per entree.

Let us represent the original average cost of entrees as = a

Hence, we have the algebraic expression

4(a - 2) = 20

4a - 8 = 20

4a = 20 + 8

4a = 28

Divide both sides by 4

4a/4 = 28/4

a = 7

Therefore, the original average cost of the entrees if the discount is $2 per entree is $7.

Delilah can do 46 jumping jacks per minute.

Step-by-step explanation:

If your question is: Ashley can ride her bicycle 15 miles in 2 hours. There are 60 miniutes in an hour and there are 1760 yards in 1 mile. How many yards does Ashley travel each minute?

____________________________________

First, do 15 miles divided by 2 hours. In addition, do 1 hour divided by 60 minutes (1). Thus, do 1760 yards divided by 1 mile. Therefore, you can multiply these together to get 220 yards/min.

Answer:

x < -14

Step-by-step explanation:

Solve the inequality  x − 2 > 2x + 12 for x:

First, subtract x from both sides.  In the resulting inequality x is on the right side with +12:

-2 > x + 12

Subtract 12 from both sides to isolate x:

-14 > x OR x < -14
