Answer:

100 and 1,00

i am smart

Answer:

90

Step-by-step explanation:

9x10 is nine ten times or ten nine times

9+9+9+9+9+9+9+9+9+9=90

or

10+10+10+10+10+10+10+10+10=90

An easy trick for doing anything muliplied by 10 is to just add an extra 0 on the end of the first number!

Answer:

x > 4

Step-by-step explanation:

if x were to equal 4, then we would have 12 - 7 > 5 which when we simplify it, we know it's not true because it would be 5 > 5 which is incorrect. That means that the lowest number x could possibly be is 5 because when substituted and simplified, we get 8 > 5 which is correct. The answer I put means that x has to be greater than 4 because if x was any number greater than 4, it would make the inequality true.

(sorry if this is confusing, I'm not really good at explaining things. I hope it helped anyway)

Answer:

x>4

Step-by-step explanation:

When solving an inequality, treat it exactly like you would when solving an equation. Perform reverse operations on both sides of the inequality to cancel values out and isolate the variable, which in this case, is x. The only difference is if you were to multiply or divide both sides by -1, you must reverse the inequality (ex. > turns into <)

[tex]3x -7 > 5[/tex]

Add 7 to both sides    

[tex]3x -7+7>5+7\\3x>12[/tex]

Divide both sides by 3

[tex]\frac{3x}{3}>\frac{12}{3}\\x>4[/tex]

Answer:

40 by 2.5 ?

Step-by-step explanation:

Answer:

Step-by-step explanation:

To find the equation of the line in slope-intercept form we to find the y-intercept(b) and the slope(m)

For the y-intercept(b) we can see that the line crosses/intersects the y-axis at 40 so the value of b equals 40 which means our y-intercept is 40

now all that is remaining is the value of m which we can find through the formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

we take any two coordinates which lie on the line for example

(0 , 40) and (2 , 140) and plug it into our formula

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{140-40}{2-0}\\\\m=\frac{100}{2} \\\\m=50[/tex]

so the slope of the line is 50 which is m , so the equation of the line in slope-intercept form would be:

[tex]y=mx+b\\y=50x+40[/tex]

The answer would be...

-3/8

Answer: no they are not simular and the reason for this is because not only are one of the sides off but one of the x values on the first one is not equal.

Answer:

Yes, they are similar.

Step-by-step explanation:

The two triangles have at least one angle that is the same.

(I am most definitely NOT sure about this one btw)

The width of the original is 11 inches.

The ratio of the width is 14/11

Set up a ratio for the new length:

14/11 = 14/X

Cross multiply:

11x = 196

Divide both sides by 11:

x = 196/11

x = 17.8 inches. (Rounded to the nearest tenth)

Answer:

Original width: 11 inches.

ratio: 14/11

Answer:

y=3.14x

Step-by-step explanation:

if you graph this on a calculator you can just visually see what line lines up with all the points. but you can also plug in one of the points into the equations to see if its true or not and if its true choose that equation. like use the first points (2, 6.28) and plug them into the equations and see which one is true.

The equation best represents the given data is y=3.14x. Therefore, option C is the correct answer.

Given that, a student measured the diameter and circumference of several circular objects.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)

From the table we have (2.0, 6.28) and (5.3, 16.64)

Now, slope = (16.64-6.28)/(5.3-2.0)

= 10.36/3.3

= 3.14

Substitute m=3.14 and (x, y)=(2.0, 6.28) in y=mx+c, we get

6.28=3.14(2.0)+c

c=0

Substitute m=3.14 and c=0 in y=mx+c, we get

y=3.14x

The equation best represents the given data is y=3.14x. Therefore, option C is the correct answer.

Answer:

at 0 that is when it starts to increase until it hits the 2  on the y- axis. Then there is the constant speed that starts at 1 then ends on 2 on the x-axis. As soon as the constant speed stops it decreases to the number 3 then back at a constant speed to decrease again.

Answer:  2.3 × 0.4 = 0.92 .

2.3 × 1 = 2.3

0.92 + 2.3 = 3.22

Step-by-step explanation:

When decimal points are left out until the end, you can count the number of decimal places to the right of the decimals in the factors and then insert the decimal in the product, counting places right to left.

The factor 2.3 has one decimal place. The factor 0.4 has one decimal place.

Thats a total of 2.

92 becomes .92 when the decimal is inserted two places to the left.

230 becomes 2.30 when the decimal is inserted two places to the left.

Answer:

∡ABC=55°

Step-by-step explanation:

Step 1: Identify all angles

∠A=(x+45)°

∠B=(6x+5)°

∠C=(3x)°

∠ABC=(180-∠B)°=(180-(6x+5))°

Step 2: Use the Triangle Angle Sum Theorem

∠A+∠ABC+∠C=180°

(x+45)+(180-(6x+5))+(3x)=180

x+45+180-6x-5+3x=180

-2x+45+180-5=180

-2x+45-5=0

-2x+40=0

-2x=-40

x=20

Step 3: Plug in x=20 for ∠ABC

∠ABC=(180-(6x+5))°

(180-6(20)-5)°

(180-120-5)°

(60-5)°

55°

So ∡ABC=55°

Answer:

∡ABC=55°

Step-by-step explanation:

Step 1: Identify all angles

∠A=(x+45)°

∠B=(6x+5)°

∠C=(3x)°

∠ABC=(180-∠B)°=(180-(6x+5))°

Step 2: Use the Triangle Angle Sum Theorem

∠A+∠ABC+∠C=180°

(x+45)+(180-(6x+5))+(3x)=180

x+45+180-6x-5+3x=180

-2x+45+180-5=180

-2x+45-5=0

-2x+40=0

-2x=-40

x=20

Step 3: Plug in x=20 for ∠ABC

∠ABC=(180-(6x+5))°

(180-6(20)-5)°

(180-120-5)°

(60-5)°

55°

So ∡ABC=55°
