Answer:

42.22 (2 repeating)

Step-by-step explanation:

When you are given percentage problems, you deal with the percent (%), base (amount you are starting with), and the amount.

Starting with the most basic equation,

Percent * Base = Amount

In this problem, you are given the amount (38) and the percent (90)

So to find the base, you can do

Base = Amount / Percent

As always, convert the percent to a decimal by dividing by 100.

38/ 0.9 = 42.222 repeating

Answer:

38 is 90 Percent of What Number?

42.22

Answer:

4th root of 16

4 = index ; 16 = radicand

2

Step-by-step explanation:

⁴√16 is pronounced as the 4th root of 16

For expressions of this sort :

The index = 4

Radicand = 16

Sqareroot (√) is a radical symbol, and the number under the radical square root Symbol is called the radicand

Hence. The 4th root of 16:

⁴√16 ; using a calculator gives 2.

We could check our resukt by taking the 4th square of 2

2 * 2 * 2 * 2 = 16

Answer:

option 1: [tex]\frac{40}{9}[/tex]

Step-by-step explanation:

tan = [tex]\frac{opposite}{adjacent}[/tex]

tan A = [tex]\frac{40}{9}[/tex]

Answer:

Option 3

Step-by-step explanation:

So remember the formula for sine, cosine, and tangent: it's SOH CAH TOH. SOH is sine: opposite over hypotenuse. Cosine is CAH: adjacent over hypotenuse. Lastly, the one we're using today is tangent, TOH: opposite over hypotenuse. So for tan A, you look at the opposite side of angle A, which is side BC; the length is 40. Then you look at the hypotenuse, which is side AB; the length is 41. So, you get 40/41, which is option 3 as the answer. Hope this helps!

Answer:

A. 180 m²

B. 540 pounds

Step-by-step explanation:

Area of rectangular playground = length × width

Length of a Rectangular playground = 15m

width of the playground =

12m

Area of rectangular playground = length × width

= 15m × 12m

= 180m²

B. 1m square = 3 pounds

What will be the total amount he will charge for leveling the playground.

Total cost of leveling the playground = 180 m² × 3 pounds

= 540 pounds

Answer:

36 = Dividend

6 = Divisor

6 = quotient

Answer:

I think it's A and D

Step-by-step explanation:

For option A, y would be the height or total growth, and x would be time or months and total height = 0.23 feet × 7.5 months

for option D, y would be the total amount of money spent and x would be the number of granola bars bought.  total money spent = $0.23 × number of granola bars bought

Options B and C don't work because we don't know the initial values and an initial value would be represented in the equation.

In option E, 0.23 represents the total growth in 7 days, so it would be the total instead of the rate of change

Given:

The angles of a quadrilateral are x°, (x+5)°, (2x-25)° and (x+10)°.

To find:

The value of x.

Solution:

We know that the sum of all interior angles of a quadrilateral is 360°. So,

[tex]x^\circ+(x+5)^\circ+(2x-25)^\circ+(x+10)^\circ=180^\circ[/tex]

[tex](5x-10)^\circ=180^\circ[/tex]

It can be written as

[tex](5x-10)=180[/tex]

[tex]5x=180+10[/tex]

[tex]5x=190[/tex]

Divide both sides by 5.

[tex]x=\dfrac{190}{5}[/tex]

[tex]x=38[/tex]

Therefore, the value of x is 38.

Answer:

55 miles

Step-by-step explanation:

Given data

DIstance =  825 miles

Time = 15 hours

Speed= distance/time

Speed= 825/15

Speed= 55  miles per hour

Given that we want to find the distance traveled in 1 hour, we have

Distance= Speed*time

Distance= 55*1

Distance= 55 miles

Hence the car will travel 55 miles in 1 hour

Complete question :

Zara, Sam, Shyla, and Ryan are playing a game with marbles, Match the statements with the number lines that represent their solutions:

Two more than Shyla's score is less than 9.

Shyla's score is x;

Three times the number of marbles that

Zara has is more than 15. The number

of marbles Zara has is x;

Sam needs more than 6 points to quality

for the next level of the game. The

number of points Sam needs is x;

Two times Ryan's score is less than 12

Ryan's score is x

Answer:

x < 7 (third number line)

x > 5 (4th number line)

x > 6 (1st number line)

x < 6 (2nd number line)

Step-by-step explanation:

2 more than Shyla's score is less than 9 ; Shyla's score is x ;

x + 2 < 9

x < 9 - 2

x < 7 (third number line)

Three times the number of marbles that Zara has is more than 15. The number of marbles Zara has is x;

3x > 15 ;

x > 15 / 3

x > 5 (4th number line)

Sam needs more than 6 points to quality for the next level of the game. The number of points Sam needs is x;

x > 6 (first number line)

Two times Ryan's score is less than 12 Ryan's score is x;

2x < 12

x < 12 / 2

x < 6 (2nd number line)

Answer:

x = 45.1

Step-by-step explanation:

The angles within this all equal 360 when added together.

So we add all of these angles together, make it equal to 540, and then solve for x. :)

4x+6 + 2x+3 + 120 + 2x+10 + x-5 = 540

4x+2x+2x+x +6+3+120+10-5 = 540

9x + 134 = 540

9x = 406

x = 406/9

x = 45.1

Answer:

[tex]\frac{2}{9}[/tex]

Step-by-step explanation:

The probability of an event is calculated by dividing the number of successful outcomes by the number of total outcomes. In an algebraic expression, that would be [tex]\frac{successful}{total}[/tex].

In this case, there are a total of [tex]20+15+10=45[/tex] ways to choose any ball, since there are [tex]45[/tex] balls in the box. However, only [tex]10[/tex] are yellow, so there are [tex]10[/tex] ways to successfully choose a yellow ball. Therefore, the probability of choosing a yellow ball is [tex]\frac{10}{45}=\frac{2}{9}[/tex]. Hope this helps!

The triangle is a 45-45-90, so the formula states that the hypotenuse is 2 roots of x, so x is one.

Answer:

Arithmetic sequence

Step-by-step explanation:

In an arithmetic sequence, the next term on the sequence is obtained by adding a certain value to the first term. This term that is added is uniform throughout the sequence. Once this term is added to the preceding term, the next term of the sequence is obtained. This term that is thus added is known as the common difference of the arithmetic sequence.

So the arithmetic sequence obtained by adding 4 starting from 2 is; 2, 6, 10, 14 .........

Answer:

x=42.3m

Step-by-step explanation:

x/47=82.8/92

92x=3891.6= 42.3m is the distance

Given that the triangles formed are similar, the distance between the two campsites is: 42.3 m.

Triangles that are similar to each other always have the same shape but different sizes, and the ratio of their corresponding sides are equal (proportional).

The two triangles formed are similar triangles. Therefore:

47/FG = 82/73.8

Cross multiply

FG = (47 × 73.8)/82

FG = 42.3 m

Therefore, given that the triangles formed are similar, the distance between the two campsites is: 42.3 m.
