A=

[tex] \frac{a + b}{2} h[/tex]

So :

[tex]area \: = \frac{36 + 42}{2} \times 40 \\ \frac{78}{2} \times 40 = 39 \times 40 = 1560[/tex]

To find the perimeter of a shape, you need to add up the measurements of all the sides to find it. I hope this helps. Let me know if you need some help with some perimeter problems :)

Answer:

the width is (x + 4) and the length is (x + 10)

Step-by-step explanation:

The area of a rectangle is given by A = L * W, where L is the length and W the width.  

If we factor the given x^2 + 14x + 40, we get (x + 10)(x + 4).  Thus, the width is (x + 4) and the length is (x + 10).

Answer: 52%

Step-by-step explanation:

The team batted 250 times. In that time, they got 60 strikeouts, 50 flyouts and 20 groundouts.

The total number of out they got was therefore:

= 60 + 50 + 20

= 130 outs

The percent of the time they got outs out of the total is:

= 130/250

= 52%

Answer:

17/25

Step-by-step explanation:

The required total score for 100% mark is given as 25.

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Let the x be the be score for 100% marks.
68% of x = 17
x = 17 / 68%
x = 25

Thus, the required total score for 100% mark is given as 25.

Answer:

140

Step-by-step explanation:

The two non supplementary angles not supplementary to x = the sum of those two angles. So the sum = 57 + 83 = 140

x = 140

Answer:

[tex]x=80^{\circ}[/tex]

Step-by-step explanation:

Solution 1:

Recall that in an isosceles triangle, the two angles adjacent to the congruent sides are equal. Since the sum of interior angles in a triangle add up to [tex]180^{\circ}[/tex], we set up the following equation:

[tex]x+50+50=180[/tex].

Solving, we get:

[tex]x+100=80,\\x=\fbox{$80^{\circ}$}[/tex].

Solution 2:

The Law of Sines states:

[tex]\frac{\sin A}{a}=\frac{\sin B}{b}=\frac{\sin C}{c}[/tex], for any triangle.

We can use this to set up a proportion with the information given:

[tex]\frac{\sin x}{18}=\frac{\sin 50^{\circ}}{14}[/tex].

Solving, we get:

[tex]x=\arcsin(\frac{18\cdot \sin 50^{\circ}}{14}),\\x \approx \fbox{$80^{\circ}$}[/tex].

Answer:

Darlene bought more fabric

Darlene bought 3.4 yards more

Step-by-step explanation:

Darlene = 7 yards + 20% extra

= 7 yards + (20% of 7 yards)

= 7 + (20% × 7)

= 7 + (0.2 × 7)

= 7 + 1.4

= 8.4 yards

Chris = 4 yards + 25% of 4 yards

= 4 yards + (25% of 4 yards)

= 4 + (25% × 4)

= 4 + (0.25 × 4)

= 4 + 1

= 5 yards

Darlene bought more fabric

How much more?

Darlene - Chris

= 8.4 yards - 5 yards

= 3.4 yards

Darlene bought 3.4 yards more

Step-by-step explanation:

The Graph of a Function

Given the function:

Answer: -4x + y = 5 in slope intercept form is 4x + 5

Answer: y= 4x + 5

Step-by-step explanation:

The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.

y = mx + b

Rewrite in slope-intercept form.

Add 4x to both sides of the equation.

y = 5 + 4x

Reorder 5 and 4x.

y= 4x + 5

Answer: Felix paid for 11 months.

Step-by-step explanation:

Let x = Number of months

Given: Annual fee = $ 20

charge per month = $15

Total amount = Annual fee + (charge per month) x (number of months)

[tex]\Rightarrow\ 185 = 20+15x\\\\\Rightarrow\ 165=15x\\\\\Rightarrow\ x = \dfrac{165}{15}\\\\\Rightarrow\ x =11[/tex]

Hence, Felix paid for 11 months.

Answer:

t = 150 + 30a

Step-by-step explanation:

Treatment of Pedro costs = Expenditure for tests and medicines + fees given for appointments.

If number of appointments = a

Cost per appointment = $30

Cost of 'a' appointments = $30a

Therefore, equation representing the total cost 't' of the treatment will be,

t = 150 + 30a

Answer: 7 errands

Step-by-step explanation:

Noah wants to have at least $30. He however already has $10.50.

The amount that he needs is:

= 30 - 10.50

= $19.30

For every errand he runs, he makes $3. The number of errands needed to get to $30 is:

= 19.50/3

= 6.5

= 7 errands

Find the Slope

(−1, −2) , (3, −1)

Slope is equal to the change in y over the change in x, or rise over run.

     change in y

m =  ---------------

    change in x

The change in x is equal to the difference in x-coordinates (also called run), and the change in y

is equal to the difference in y-coordinates (also called r ise).

     y2 − y1

m =  -----------

     x2 − x1

Substitute in the values of x and y into the equation to find the s lope.

       m = −1 − (−2) /3 − (−1)

Simplify the numerator.

Multiply −1 by −2.

       m =  −1 + 2 /3 − (−1)

Add −1 and 2.

       m =  1/3 − (−1)

Simplify the denominator.

Multiply −1 by −1.

       m = 1/3 + 1  

Add 3 and 1.

        m =  1/4

Answer:

147.395348837

Step-by-step explanation:

6338 divided by 43 gives a quotient of 147 with a remainder of 17.

When dividing 6338 by 43 with remainder, we can perform long division to find the quotient and remainder.

Start by dividing the first digit of the dividend (6) by the divisor (43). The quotient is 0 since 6 is less than 43.

Bring down the next digit of the dividend, which is 3, to the right of the 0. We now have 63.

Divide 63 by 43. The quotient is 1, as 43 goes into 63 once.

Multiply the divisor (43) by the quotient (1) and subtract the result from 63:

63 - (43 x 1) = 63 - 43 = 20

Bring down the next digit of the dividend, which is 3, to the right of the 20. We now have 203.

Divide 203 by 43. The quotient is 4, as 43 goes into 203 four times.

The final remainder is 17.

Therefore, 6338 divided by 43 gives a quotient of 147 with a remainder of 17.
