What is M less than A

Answers

I think you mean to ask what is the measure of angle A.

You can find the third angle of the bottom triangle by 180 - 43 - 35 = 102

The vertical angle above it is also 102.

Then, to find the measure of angle A, you do 180 - 102 - 18 = 60

So, the measure of angle A is 60 degrees.

Answer:

60°

Step-by-step explanation:

Since Angle E is same for both triangles, as vertical angles, the sum of the other two interior angles should be same.

Then we have:

m∠A + m∠B = mC + m∠Dm∠A + 18 = 43 + 35m∠A + 18 = 78m∠A = 78 - 18m∠A = 60

m1= 43

m2=17

m3=120

m4=m5=m6=60

m7=17

m8=120

m9=43

Step-by-step explanation:

"Given ABC is an isosceles triangle and DBE is an equilateral triangle. we have to find each missing measure.

In triangle ABC,

∠1=∠9    (∵isosceles triangle)

⇒ 4x+3=9x-47

⇒ 9x-4x=3+47 ⇒ 5x=50 ⇒ x=10

Hence, ∠9=∠1=(4x+3)°=4(10)+3=43°

Also, given ΔBDE is an equilateral triangle, and all angle of equilateral triangle are equal.

∴ ∠4+∠5+∠6=180°

⇒ ∠4+∠4+∠4=180° ⇒ 3∠4 = 180° ⇒ ∠4 = 60°

∴ ∠4=∠5=∠6=60°

By exterior angle property, ∠3=∠5+∠6=60°+60°=120°

                                            ∠8=∠5+∠4=60°+60°=120°

In ΔABD, ∠1+∠2+∠3=180°

            ⇒ 43°+120°+∠2=180°⇒ ∠2 = 17°

In ΔABD, ∠9+∠8+∠7=180°

            ⇒ 43°+120°+∠7=180°⇒ ∠7= 17°"

The left and right page numbers of an open book are two consecutive integers whose sum is 23. Find these page number.

Answers

Answers: The page numbers are 11 and 12

==========================================================

Explanation:

Consecutive integers are ones that follow immediately after another. For example, the set {7,8,9,10} are consecutive.

Let,

x = first page, some positive whole numberx+1 = second page, follows immediately after page x

Adding those two said pages will lead to 23

first + second = 23

(x) + (x+1) = 23

2x+1 = 23

2x = 23-1

2x = 22

x = 22/2

x = 11 is the first page

x+1 = 11+1 = 12 is the second page

Check: 11+12 = 23 which confirms the answers.

Use f(x) = 2x − 3 and g(x) = 4 − x2 to evaluate the expression.

A composition is a operation two functions in which the independent variable of the first function is substituted by the entire second function. In other words, we have the following expressions:

[tex](f\,\circ\,g) (x) = f(g(x))[/tex] (1)

[tex](g\,\circ \,f)(x) = g(f(x))[/tex] (2)

If we know that [tex]f(x) = 2\cdot x - 3[/tex] and [tex]g(x) = 4 - x^{2}[/tex], then we have the following compositions:

[tex](f\,\circ\, g) (x) = 2(4-x^{2})-3[/tex]

[tex](f\,\circ\,g)(x) = 5-2\cdot x^{2}[/tex]

[tex](g \circ f) (x) = 4 - (2\cdot x-3)^{2}[/tex]

other. What is the value of x?

Answers

Answer:

80

Step-by-step explanation:

in the figure above, angle 100 degrees is corresponding to the angle co - interior to angle x

that is

if we put an angle that is at the upper left of x, we can call that y which is corresponding to 100 degrees

since y is corresponding to 100 degrees, it automatically becomes the same as 100 degrees

therefore y=100

now, from the first line above, we know that x and y are co-interior which means that they both add up to 180 degrees

that is

x+y=180

we know that y = 100

therefore,

x+100=180

collect like terms and

x = 180-100

therefore,

x= 80

The number T of teams that have participated in a robot-building competition for high-school students over a recent period of time x(in years) can be modeled by T(x) = 17.155x^2 + 193.68x + 235.81, 0 ≤ x ≤ 6.

After how many years is the number of teams greater than 1000? Justify your answer.

Answers

Solving the quadratic equation, it is found that the number of teams is greater than 1000 after 3.1 years.

The number of teams after x years is given by:

[tex]T(x) = 17.155x^2 + 193.68x + 235.81[/tex]

Initially, there are T(0) = 236 teams. If will 1000 be when T(x) = 1000, thus:

[tex]17.155x^2 + 193.68x + 235.81 = 1000[/tex]

[tex]17.155x^2 + 193.68x - 764.19 = 0[/tex]

Which has coefficients [tex]a = 17.155, b = 193.68, c = -764.19[/tex], then:

[tex]\Delta = (193.68)^2 - 4(17.155)(-764.19) = 89950.66[/tex]

[tex]x_{1} = \frac{-193.68 + \sqrt{89950.66}}{2(17.155)} = 3.1[/tex]

[tex]x_{2} = \frac{-193.68 - \sqrt{89950.66}}{2(17.155)} = -14.3[/tex]  

We want the positive root, so the number of teams is greater than 1000 after 3.1 years.

A recipe for 10 bran muffins calls for 1 cup of flour. The number of muffins that can be made varies directly with the amount of flour used. There are 3 1/2 cups of flour available. How many muffins can be made?

Answers

Answer:

35

Step-by-step explanation:

3 1/2 x 10 =35

make 3 1/2 into an improper fraction: 3 x 2 + 1 = 7/2

make 10 into a fraction: 10/1

find the LCD (least common denominator) for each number:

10/1 = 20/2

7/2 = 7/2

20/2 x 7/2 = 70/2 = 35

:)

Answer:

35

Step-by-step explanation:

For 1 cup of flour, you make 10 muffins. Just by reading the problem, you see that the number of muffins, 10, is 10 times the number of cups of flour, 1.

For 3 1/2 cups of flour, you make 10 times that number muffins.

3 1/2 × 10 = 3.5 × 10 = 35

Answer: 35 muffins

You can also use a proportion.

1 cup flour is to 10 muffins as 3.5 cups flour is to x muffins.

1/10 = 3.5/x

Cross multiply:

1 × x = 10 × 3.5

x = 35

Answer: 35 muffins
