Answer:

T can be equal to 1 1/10 or 1.1 or 11/10

Step-by-step explanation:

10t=11

So divide by 10 on both sides.

t=11/10 which can be simplified to t=1 1/10 or t=1.1

Answer:

v = 3 ( x − 1 ) 32 ( x + 5 )

Answer:

A

Step-by-step explanation:

Ducks have 2 feet and 7x2=14

Pigs have 4 feet and 9x4= 36

36+14=50 legs

7+9= 16 heads

Answer:

Angle WTS will be 180 degree minus 15x. You can write this as an expression:

180-15x

Now you have an expression for each angle in the triangle. Triangles will always have 180 degrees in them. You can add the expressions together and set it equal to 180. Then you can solve the equation for the x variable.

Step-by-step explanation:

Angle SWT + angle WTS + angle TSW = 180 degrees

Replace each angle with the expression then solve.

Answer:

x=7.90 x≈8

Step-by-step explanation:

they are alternate interior angles

so: 7x+6+15x=180

22x+6=180

22x=174

=7.9090......

you can double check my work

Answer:

Four boys and one girl.

Step-by-step explanation:

Total students wearing glasses = 5

Separate the students by x and x + 3. It is x + 3 for the boys because there are three more boys wearing glasses.

Girls = x

Boys = x + 3

Total = 5

Calculate:

x + x + 3 =5

2x + 3 =5

2x = 2

x = 1

Boys wearing glasses = (1) + 3 = 4

Girls wearing glasses = 1

Answer:

the answer is 18.l hope is good

Answer:

y = -2x + 6

Step-by-step explanation:

The y-intercept is where the line goes through the y-axis. So, you'd want to find the value of y when x is 0.

Answer:

Step-by-step explanation:

T=56t and C=64(t-.25)

64(t-.25)=56t

64t-16=56t

8t-16=0

8t=16

t=2 hours

Answer:

Use "photo math."

Step-by-step explanation:

Answer:  x⁴y²⁰

Step-by-step explanation: Distribute the exponent ⁴ over the parentheses

(x y⁴)⁴ becomes x⁴y¹⁶  (multiply exponents)

then take the 4th root of y¹⁶  (divide the exponent of the radicand by the index)  ⁴√y¹⁶  becomes y⁴

Then multiply the factors. Add exponents

x⁴y¹⁶ * y⁴  becomes x⁴y²⁰

Answer:

triangle E

Step-by-step explanation:

imagine the X-axis as a mirror, the mirror reflects the shape or the body, and you'll see that the same distance you're away from the mirror as your reflection distance

if you want to prove that the triangle E is the reflection of the triangle A, count from the nearest point from the X-axis, you'll count 3 to reach the X-axis ,and the difference will be also 3 from the X-axis to the nearest point to the triangle E

Answer:

Okay I haven't done this in awhile but okay so (1) if you are going off of the Y's then no it would be a function X's Yes its a function, (2) None of the dots are on the same area so like if you draw a line down from where each of the dots are and it touches another dot then its not a function, but lucky for you it is a function. (3) isn't function because if you can see number 9 have 2 lines going from it so its not  (4) is a function because if you draw a bunch of lines and they don't go through the line in the middle your good. I hoped this helped you. Bye Bye.

Answer:90

Step-by-step explanation:

When the sum of two angles is 90°, then the angles are known as complementary angles. In other words, if two angles add up to form a right angle, then these angles are referred to as complementary angles.

Answer:

20

Step-by-step explanation:

8% × 250 =

(8 ÷ 100) × 250 =

(8 × 250) ÷ 100 =

2,000 ÷ 100 =

20;

Answer:

3.8%×250=

9.5

so the answer is 9.5

Answer:

{2, 3, 4, 6, 8, 9, 12, 18}

Step-by-step explanation:

If A= {x: xis a factor of 72}

A = {2, 3, 4, 6, 8, 9, 12, 18, 36, 72}

If B= {x: 2x+3<2x-3).

-2x+3 <2x-3

-2x - 2x < -3-3

-4x < -6

x > 3/2

If

C= {x:x<20}

C = {-∞, 19}

The intersection of the sets AnBnc = {2, 3, 4, 6, 8, 9, 12, 18}

Note that intersection means all the elements common to the three sets

Answer:

u have the right answer for the question

Answer:

Ok so you have to figure out what is the input, output, y-intercept (b), slope (m), and equation.

First, input is the x. Looking at the graph.

Input : 0, 10, 20

Second, output is the y. Looking at the graph.

Output : 20, 30, 40

Third, y-intercept is the b in the equation of y = mx + b. Looking at the graph.

Y-intercept (b) : 20

Fourth, slope is the m in the equation of y = mx + b. Looking at the graph.

Slope (m) : 1/2

Fifth, you have to find the equation in the form of y = mx + b. Looking at the graph.

Equation : y = 1/2x + 20

I hope this helps and if you have any other questions I would be glad to answer it, thank you :) !!
