CAN SOMEONE PLEASE HELP ME WITH THESE 2.

Answer:

90 cm^3

5*4*3=90

Answer:

[tex]\huge\boxed{\tt{x = 50}}[/tex]

Step-by-step explanation:

3x + 30 = 180 (Angles on a straight line add up to 180 degrees)

Subtract 30 to both sides

3x = 180 - 30

3x = 150

Divide 3 to both sides

x = 150 / 3

x = 50

Answer:

139.36

Step-by-step explanation:

first you do 8*8 because that would be the area of the square part

8*8=64

then find the area of the semicircle

first the Radis of it is 4 because 8/2=4

A=3.14R^2/2

3.14*4^2/2

3.14*16/2

50.24/2

25.12

now because there are 3 of the semicircles you do

25.12*3

75.36

then you add the 64 from the square to get your answer

75.36+64

139.36

Answer:

The measure of A is 93

Step-by-step explanation:

Here, we want to get the measure of angle A

we can start by getting the measure of angle C

Mathematically, we can use sine rule

It states that the ratio of the length of a side of a triangle and the sine of the angle it faces is constant

So to get C, we have the following;

9/sin 38 = 11/sin C

sin C = 11sin 38/9

sin C = 0.7525

C = sin^-1(0.7525)

C = 48.80

This is approximately 49

To get A,

we know that if we added the measure of interior angles of a triangle, the addition is 180 degrees

Thus, we have it that:

38 + 49 + A = 180

A = 180-38-49

A = 93

Step-by-step explanation:

Let the cheese pizzas be denoted by x.

Since pepperoni pizzas is 4 less than twice the number of cheese pizzzas. This will be:

= (2 × x) - 4.

= 2x - 4

Since combo pizzas is 8 less than the number of cheese pizzas. This will be:

= x - 8

Then we add all the pizzas and equate to 110. This will be:

x + (x - 8) + (2x - 4) = 110

x + x - 8 + 2x - 4 = 110

4x - 12 = 110

4x = 110 + 12

4x = 122

x = 122/4

x = 30.5

Therefore, cheese pizza = 30.5

Combo pizza = x - 8 = 30.5 - 8 = 22.5

Pepperoni pizza = 2x - 4 = 2(30.5) - 4 = 57

Answer:

Given f(x) = x2 + 3x – 1, find

a) f(1)

b) f(–1)

c) f(a)

d) f(x – 1)

Step-by-step explanation:

a) f(1) = (1)2 + 3(1) – 1 = 3

b) f(–1) = (–1)2 + 3(–1) – 1 = –3

c) f(a) = a2 + 3a – 1

d) f(x – 1) = (x – 1)2 + 3(x – 1) – 1

= x2 – 2x + 1 + 3x – 3 – 1 = x2 + x –3

Answer:

5/7

Step-by-step explanation:

Multiply the numerator with the numerator and the denominator with the denominator. This makes the fraction 30/42. Simplify this to get 15/21. You can simplify it again to get 5/7.

what question?

Step-by-step explanation:

Answer:

0.41 cents

Step-by-step explanation:

2.46/6 = 0.41

Answer:

m∠A = 45⁰

m∠B = 75⁰

Step-by-step explanation:

Given question 4;

m∠A = x + 51

m∠B = 81 + x

m∠C = 60⁰

The value of the missing angles can be determined by the finding the value of x first;

m∠A  +  m∠B  + m∠C = 180⁰ (sum of angles in a triangle)

(x + 51)  +  (81 + x)  +  60⁰ = 180

(x + x) + (51 + 81 + 60) = 180

2x + 192 = 180

2x = 180 - 192

2x = -12

x = -12/2

x = -6

Thus, the values of the angles are calculated as follows;

m∠A = x + 51

         = -6 + 51  

          = 45⁰

m∠B = 81 + x

        = 81 - 6

         = 75⁰

Answer:

$160,500

Step-by-step explanation:

First, find the coming years sales

7% of 1,500,000 is 105000

105,000+1,500,00=1,605,000

1,605,000 is the next year's sales and we do that *0.1 to find the advertising.

1,605,000*0.1=160,500

So 160,500 will be set aside for advertising

2x+4<10

Subtract 4 from both sides to cancel it out.

2x+4<10

   -4   -4

2x<6

Now divide 2 from both sides to cancel that out.

2x<6

/2  /2

x<3

So that's the answer.

Answer:

5

Step-by-step explanation

Answer: 5

Step-by-step explanation:

aₙ = a + (n - 1) d

n = the term of the sequence that you're looking for (2)

a = 1st term of sequence (2)

d = common difference (3)

a₂ = 2 + (2 - 1) 3

a₂ = 2 + (1 × 3)

a₂ = 2 + 3

a₂ = 5

It's also given btw but in case you wanted to find other terms of the sequence.

Answer:

21 1/3

Step-by-step explanation:

we turn the fraction into an improper fraction...

Answer:

$20 was how much money he had before he spent any money.

Step-by-step explanation:

So, with any problem like this, all you have to do to figure out the answer is to add how much money is left and how much was spent. So, like this:

Amount left + Amount spent = Original Amount

Answer:

1 1/3= 4/3     1 1/2= 3/2

4/3 x 3/2= 12/6 or 1/2

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

to figure this out we need to convert the whole numbers into fractions with the same denominator as the fraction that is put with them

1 1/3 --> 3/3 + 1/3 = 4/3

1 1/2 --> 2/2 + 1/2 = 3/2

then we can take those values and multiply accordingly

4/3 * 3/2 = 2

(NOTE: if the problem allows it, you can convert the fractions into decimals by dividing the numerator by the denominator (3 / 2 = 1.50) but if it doesnt, then you can use this method in other problems)

hope this helps :)
