Help me pls I’m failing Math I have An C

Answer:

80-32=48(5/9)=26.67 C; 35-32=3(5/9)=1.67 C

r = 3 Cm

h = 10 Cm

Volume

v = πr²t

= 3,14 x 3 x 3 x 10

= 9,42 x 3 x 10

= 28,26 x 10

Answer:

Step-by-step explanation:

If the area of trapezoid is 100 cm²what is the perimeter of the trapezoid?

Area of a trapezoid = 100cm

= 1/2(a + b) × h = 100cm²

Perimeter of a trapezoid = a + b + h

Answer:

EFG = 104°

GFH = 76°

Step-by-step explanation:

The sum of a linear pair is always equal to 180°

So lets solve for the variable n

2n + 32 + 4n + 16 = 180

6n + 48 = 180

6n = 132

n = 22

So now we know N

EFG = 4n + 16

EFG = 88 + 16

EFG = 104°

GFH = 2n + 32°

GFH = 44 + 32

GFH = 76°

5 odd numberis there 31,33,35,37,39

Five odd numbers are greater than 30 and less than 40 .

What is odd number?

Odd numbers are those that cannot be evenly divided by two. It cannot be evenly split into two different integers. An odd number will leave a reminder when divided by two. 1, 3, 5, 7 are example of odd numbers.

The odd number between 30 and 40 are 31,33,35,37,39.

Therefore, total number of odd numbers which are greater than 30 and less than 40 are 5.

Answer:

No they are not equivalent

Step-by-step explanation:

The given expressions are r + 4(2 + r) – 12, and  8 + 2r – 6

Let us first put r= 2 in the above expression

2+4(2+2)-12= 6

and 8+2(2)-6 = 6

Now let us put r=5 in the above two expressions

5+4(2+5)-12 = 21

similarly, 8+2(5)-6 = 12

Clearly, the two expressions are not equivalent when we put r=2 and r=5 as the values coming are different.

Answer:

the first expression is 6.

the second expression is 12.

they are NOT equivalent.

Answer:

  see attached

Step-by-step explanation:

For this exercise, it is convenient to define a, b, c as the side lengths in increasing order. (The only thing that really matters is that c=longest.)

Below, we have used a spreadsheet to do the calculations.

When a^2+b^2 > c^2, the triangle is acute. For "<", the triangle is obtuse. For "=", the Pythagorean theorem is satisfied and the triangle is a right triangle.

_____

Additional comment

The measure of the largest angle in the triangle is ...

  α = arccos((a²+b²-c²)/(2ab))

Knowing that the cosine is negative for angles larger than 90° helps me remember how the relationship of a²+b² to c² relates to the shape of the triangle.

Answer:

One angle is 46° and the other angle is 44°

Step-by-step explanation:

Complementary angle means the angles add up to 90 so:

90 - 44 = 46

Answer:

[tex]T _{n} = a + (n - 1)d \\ T _{n} = 13 + (n - 1) \times - 6 \\ T _{n} = 13 - 6(n - 1) \\ T _{n} = 13 + 6(1 - n)[/tex]

Answer:

a = [tex]\frac{1}{2}[/tex] , b = 5, and  [tex]\frac{2b}{a}[/tex] = 20

Step-by-step explanation:

f(x) = - x² + b, x ≤ 0     You would use this equation for f(-2). Since -2 is less than 0.

f(x) = - x² + b, x ≤ 0   ← You can ignore the x ≤ 0 part.

f(-2) = - (-2)² + b         Input the value -2 as x. The question states that f(-2) =1.

1 = - (-2)² + b              So switch f(-2) with 1 on the left side only.

1 = - (4) + b                Simplify. Do the exponents first, so (-2)² = 4.

1 = - 4 + b

+4  +4                      Do inverse operations

5 = b

Next,

f(x) = 2ax +3, x > 0      You would use his equation for f(2). Since 2 is greater than 0.

f(x) = 2ax +3, x > 0   ← You can ignore the x > 0 part.

f(2) = 2a(2) + 3             Input the value 2 as x.

f(2) = 4a +3           Simplify. The equation states f(2) = 5. So switch f(2) with 5

5 = 4a +3              on the left side only.

-3        - 3                     Do inverse operations

2 = 4a                          

[tex]\frac{2}{4}[/tex] = [tex]\frac{4a}{4}[/tex]                           Divide 4 on both sides to isolate the variable a

[tex]\frac{2}{4}[/tex] = a                            Simplify

[tex]\frac{1}{2}[/tex] = a

Then,

The second part says to find [tex]\frac{2b}{a}[/tex]

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

[tex]\frac{2(5)}{(\frac{1}{2}) }[/tex]                  Input both the values of a and b

[tex]\frac{10}{\frac{1}{2} }[/tex]                    Simplify

20.

The answer for a is [tex]\frac{1}{2}[/tex], the answer for b is 5, and the answer for [tex]\frac{2b}{a}[/tex] is 20.

The correct option is 3.

Step-by-step explanation:

The HL theorem states that 'if the hypotenuse and one leg of a right triangle are congruent to the hypotenuse and one leg of another right triangle, then the triangles are congruent.'

From the given figure it is noticed that triangle ABC and triangle EDC. In triangle  ABC and triangle EDC, hypotenuses of triangles are AB and DE respectively.

To use HL hypotenuse and one leg of triangles must be equal.

               AB=DE             (hypotenuse)

              AC=DE              (leg)

               BC=ED                       (leg)

Therefore the additional information    will allow you to prove the triangles congruent by the HL Theorem. Option 3 is correct.

Answer:

Equation: 3(x+5)=60

Solution: 15 inches

Step-by-step explanation:

Let x represent the original side length of the equilateral triangle. Then, the new length of each side is x+5. Because a triangle has three sides, the new perimeter is 3(x+5), which is 60 inches. Dividing both sides by 3, we get that x+5=20, so x=15.

Using the intersecting chord theorem you multiply the two lengths of one line together to equal the multiplication of the two dimensions on the second line.

The answer would be 15(4) = 5x

Answer:

C.

Step-by-step explanation:

I. If angles 1 and 2 are supplementary, then the sum of their measures is 180.

II. m<1 = 110

Now we can find the measure of <2.

m<1 + m<2 = 180

110 + m<2 = 70

III. m<1 + m<2 + m<3 = 180; m<3 ≠ 0

We know the measures of angles 1 and 2, s we can find the measure of angle 3.

110 + 70 + m<3 = 180

180 + m<3 = 180

m<3 = 0

The measure of angle 3 must be zero according to statements I and II. According to statement III, the measure of angle 3 is not zero.

Answer: C.

Answer:

Step-by-step explanation:

Usually you do it by factoring into primes. But this choice of numbers has no common primes, so all three make up the LCM

7 * 10 * 3

210 = LCM

LCM of 4 10 and 12

4: 2 * 2

10: 2 * 5

12: 2*2*3

LCM: 2 * 2 * 3 * 5 = 60

If you don't find the LCM then the answer would be 480

Answer:

210

Step-by-step explanation:

When finding the LCM(least common multiple) you need to factor each number into the product of prime number also called finding the prime factorization. Both 7 and 3 are prime, so they do not need to be factored further. However, 10 can be factored into 5 x 2.

3 - 3

7 - 7

10 - 5 x 2

By looking at the factors above, you notice none of them are the same, so none of the numbers share factors. This means you can just multiply all the factors to get the LCM:

3 x 7 x 5 x 2

Option (3)

Step-by-step explanation:

Given expression is,

[tex]\frac{2^3\times 125^\frac{2}{3}\times 81^\frac{3}{4}}{8^\frac{1}{3}\times 9\times 5^2}[/tex]

To solve the given expression we will apply the law of exponents,

[tex]\frac{2^3\times 125^\frac{2}{3}\times 81^\frac{3}{4}}{8^\frac{1}{3}\times 9\times 5^2}=\frac{2^3\times (5^3)^\frac{2}{3}\times (3^4)^\frac{3}{4}}{(2^3)^\frac{1}{3}\times (3^2)\times 5^2}[/tex]

                    [tex]=\frac{2^3\times (5^{3\times \frac{2}{3}})\times (3^{4\times \frac{3}{4}})}{(2^{3\times \frac{1}{3}})\times (3^2)\times 5^2}[/tex]

                    [tex]=\frac{2^3\times 5^2\times 3^3}{2\times 3^2\times 5^2}[/tex]

                    [tex]=\frac{2^3}{2}\times (\frac{5^2}{5^2})\times (\frac{3^3}{3^2})[/tex]

                    [tex]=2^{3-1}\times (1)\times 3^{3-2}[/tex]

                    [tex]=2^2\times 1\times 3[/tex]

                    [tex]=12[/tex]

Therefore, Option (3) will be the correct option.

Answer:

Step-by-step explanation:

The equation for the speed is:

From the equation we see for the same t the speed is greater if d is greater.

We can show that if add a vertical line to a graph and compare the d- values of the intersection of the vertical line with the graphs of the cars.

It obvious the graph of the Car B will have a greater d- value.

It means that Car B has a greater speed so it is faster that Car A.

Answer:

Refer to attachment .

Step-by-step explanation:

We need to plot the graph of ,

[tex]:\implies[/tex] y = 35x + 2

Plot different values of x :-

[tex]:\implies[/tex] y = 35*1 + 2

[tex]:\implies[/tex] y = 35 + 2

[tex]:\implies[/tex] y = 37

[tex]\rule{200}2[/tex]

[tex]:\implies[/tex] y = 35*2 + 2

[tex]:\implies[/tex] y = 70 + 2

[tex]:\implies[/tex] y = 72

Hence now plot the points (1,37) and (2,72) .

Answer:

Disagree

Step-by-step explanation:

10^0

According to the laws of indices, anything raised to the power of 0 will equate to 1. Therefore, based on this established mathematical principle, Noah's assertion about 10^0 being equal to 0 is false.

Hence, I disagree.
