PLS, 10 Mins LEFT HELP ME!!!

Answer:

15

Step-by-step explanation:

The grade percentage of Marco is 50%.

A percent is a dimensionless number, meaning that it has no units of measurement, since it represents a part of whatever whole is being measured.

Given that, Marco got 15 questions wrong on his 30-question test.

We need to find his grade as a percent,

So,

Since he got 15 answers wrong,

Therefore, his correct answers = 30-15.

That mean his grade in marks = 15

Now, his grade in percent = 15/30 x 100 = 50%

Hence the grade percentage of Marco is 50%.

Answer:

x = 109°

Step-by-step explanation:

x° is 37° + 72°, due to exterior angle property.

so x° = 109°

Answer:

Similarities: both have a base which extends into a single vertex.

Differences: a cone only has 1 edge and a pyramid has a minimum of 6 (for a triangular pyramid).

the base of a pyramid is a polygon - the base of a cone is a curve

(a mathematical cone has no edges at all it is a continuous sheet - or two sheets if you consider the vertex as dividing the surface into two sheets).

Step-by-step explanation:

brainliest?

The key difference between Pyramids and cones are:
A pyramid is basically a code that has a base in the form of a polygon.

Pyramids and cones are alike in the following ways:

Because a cone can be made from a right angle triangle, their formulas are also alike in some ways. Notice that both formulas are related to the height of the object.

The formula for the area of a right angle triangle is:

A =   hb/2

The area of a cone is given as:

A = [tex]\pi[/tex] r (r + [tex]\sqrt{(h²+r²)}[/tex]

Answer:

0.3571

Step-by-step explanation:

Step 1: Start by setting it up with the divisor 14 on the left side and the dividend 5 on the right side like this:

14[tex]\sqrt{x}[/tex]5

Step 2: The divisor (14) goes into the first digit of the dividend (5), 0 times(s).

Therefore, put 0 on top:

14[tex]\sqrt{x}[/tex]0 5

Step 3: Multiply the divisor by the result in the previous step (14 x 0 =0) and write that answer below the dividend.

14 0

  [tex]\sqrt{x}[/tex]5

   0

Step 4: Subtract the result in the previous step from the first digit of the dividend (5-0 = 5) and write the answer below.

14 0

Answer:

A) -p + 38

B) k + 1

C) a_n = 4n + 1

D) a_n = 7n - 6

E) a_n = 14 - 4n

Step-by-step explanation:

A) 5(p + 6) - 2(3p + 4)

Multiply out the bracket to get;

5p + 30 - 6p + 8

>> -p + 38

B) 7(k - 2) - 3(2k - 5)

Multiply out the bracket to get;

>> 7k - 14 - 6k + 15

>> k + 1

C) Sequence is;

5, 9, 13, 17, 21

This is clearly an AP(arithmetic progression) because the difference between each term is 4.

Formula for nth term of an AP is;

a + (n - 1)d

Where d is difference and a is first term

Thus;

a_n = 5 + (n - 1)4

a_n = 5 + 4n - 4

a_n = 4n + 1

D) Sequence is 1, 8, 15, 22, 29.

This is also an AP.

Difference is 7.

Thus,nth term is;

a_n = 1 + (n - 1)7

a_n = 1 + 7n - 7

a_n = 7n - 6

E) 10, 6, 2, -2, -6

This is also an AP.

Difference is -4

Thus,

a_n = 10 + (n - 1)(-4)

a_n = 10 - 4n + 4

a_n = 14 - 4n

Answer:

Well in order to find the y-intercept, the “x” has to be 0. To find that we need to find the pattern and to ind the pattern you would need to find the slope. The slope is -4 or 4/ -1

So the Y is 4 and the X is -1

So use that to add or subtract for the pattern

1, -4

0, 0

The y- Intercept is 0 or option (A)

Answer:

6:9 or (2:3)

Step-by-step explanation:

A ratio is a term that gives comparison of values. It helps to determine

how much of a particular thing that is compare to other thing.

Given:

numbers of blue marbles= 6

numbers of red marbles= 9

Hence, ratios that represent the numbers of blue marbles to red = 6:9

We can reduce it using factor of 3, hence the ratio becomes(2:3)

Answer:88

Step-by-step explanation:

1.10c+2.35s=294.20

C+S=172

1.10c+2.35s=294.20 if you multiply by 100.

110c+235s=29420

-110 (cones + sundaes =172)

-110c-110s=-18920

125s/125=10500/125

S= 84

C+84=172

-84. -84

C= 88
