Answer:

x = 13

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

Here A = 55, h = 5. b₁ = x, b₂ = 9, then

[tex]\frac{1}{2}[/tex] × 5 × (x + 9) = 55

2.5(x + 9) = 55 ( divide both sides by 2.5 )

x + 9 = 22 ( subtract 9 from both sides )

x = 13

question 1 :- sum of all angles of a triangle is 180°

so, x + 39° + 25° + 15° = 180°

⇒x + 79° = 180°

⇒x = 101°

question 2 : draw the along with AD and make and triangle as shown in figure.

as ABCD is a parallelogram. so, angle FDE = 180° - x

and angle FED = 180° - x [ as FEA + FED = 180° ]

now from ∆DEF,

50° + 180° - x + 180° - x = 180°

⇒230° - 2x = 0

⇒x = 105°

also read : If (A + B) =(A-B) then the angle between the Ả and B.

Step-by-step explanation:

One complete tenths block would represent 1 which is a whole number. In the problem, two of the tenths squares are filled in which means that that part is equal to 2. In the third block, that represents 4/10 or 0.4. Putting them together would equal 24/10, 2 4/10, and 2.4

Answer:

Part A: 6.0 ft, 5.4 ft

Part B: 22.8 feet

Part C: Parallelogram

Answer:

A = 3.4

Step-by-step explanation:

235 = 7(4 + 6a) - 3

you're trying to make both sides equal, that means whatever is happening on one side must happen on the other. to take minus 3 out of the equation you add 3 to both sides

235 + 3 = 7(4 + 6a) -3 + 3

238 = 7(4 + 6a)

next add within the parenthesis and multiply that by 7

238 = 7(4 + 6a)

238 = 7 × 10a

238 = 70a

next divide both sides by 70

238 ÷ 70 = 70a ÷ 70

3.4 = a

Answer: For #5, a = 5

Step-by-step explanation:

First, let's open the parenthesis.

235 = 7 (4 + 6a) - 3

235 = 28 + 42a - 3

Next, subtract 28 by 3 on the right side.

235 = 28 + 42a - 3

235 = 25 + 42a

Then, we'll subtract both sides by 25.

235 - 25 = 25 - 25 + 42a

210 = 42a

Finally, let's divide both sides by 42!

210 / 42 = 42a/42

5 = a

So, a = 5.

Answer:

y > 19x - 2

Step-by-Step Explanation:

Slope-intercept form is y = mx + b. In this case it is y > mx + b.

2 is our b and 19x is our mx.

We need to put the y on one side and the other terms on the other side of greater than sign. When we switch which term the side is on, we have to change the operation. If it is a negative number it turns positive and vice-versa. Our y can't be negative so we need to put it on the right side to change it to a positive.

19x > y + 2

Now we need to get the 2 on the same side as the 19x. So we bring it to the other side and switch the operation.

19x - 2 > y

Now we are just going to flip both sides to get the y on the left and the 19x - 2 on the right.

y > 19x - 2

I hope thay made sense.

Step-by-step explanation:

Answer:

The relation is a function.

To analyze if the relationship shown is a function, you must observe that each value of the domain has a single value of the range assigned. For the given points {(-5, 6), (-2, 3), (3, 2), (6, 4)} this requirement is satisfied. Therefore, the relationship is a function.

Step-by-step explanation:

Since there is one value of  y  for every value of  x  in  ( − 5 , 6 ) , ( − 2 , 3 ), ( 3 , 2 ), ( 6 , 4 ) , this relation is a function.

The relation is a function.

Answer:

3400

Step-by-step explanation:

When you round to the tens place you look at the number in the ones place. If it is 4 or less then you keep the tens place the same. If it's 5 or more then you round the tens place up one. Then you make the ones digit a 0.

Since there is a 2 in the ones place in 172, you keep the tens digit the same (170).

Since there is an 8 in the ones place in 18, you round the tens digit up one (20).

Now you multiply.

170×20=3400

I hope that made sense.

Answer:

A

Step-by-step explanation:

The line is going up so it is positive. That leaves A and B. By counting squares, you can see that the line is going up at a rate of 2/3. you find this by counting from where it crosses on y=-2 too y=0. And you see the y has changes two places and the x has changed 3. Or do it in the formula y(final)-y(initial)/x(final)-x(initial) so (0-(-2))/(3-0) = 2/3. So the equation must have 2/3. So the equation is A

Answer: x = 25

Step-by-step explanation:

3x + 48 + 57 = 180

3x + 105 = 180

-105 on both sides

3x + 105 - 105 = 180 - 105

3x = 75

divide by 3 on both sides

(3x)/x = 75/3

x = 25

The ordered pair that represents how much she spends on a 5-day week is (20,25)

The rates are given as:

[tex]Access\ Roads = \$4[/tex]

[tex]Parking\ Lot= \$5[/tex]

From the question, x represents the access to roads, and y represents the number of days she parked her car.

So, her daily expense is:

[tex]Daily = Access\ Roads \times x + Parking\ Lot \times y[/tex]

This gives

[tex]Daily = 4\times x + 5\times y[/tex]

[tex]Daily = 4x + 5y[/tex]

For a 5-day work week, her daily expense is:

[tex]Daily = 4 \times 5 + 5 \times 5[/tex]

[tex]Daily = 20 + 25[/tex]

Express as ordered pair

[tex]Daily = (20 , 25)[/tex]

Hence, the ordered pair that represents how much she spends is (20,25)
