Answer:

X = 8

Step-by-step explanation:

A triangle's degrees always add up to 180, this is a right triangle meaning that one of the degrees is 90, and we see the other one is 54, so we add these together and subtract them from 180 and set that equall to 3x+12.

Answer:

i think x= 13.5

Step-by-step explanation:

Answer:

x = 35 degrees

Step-by-step explanation:

supplementary angles = 180 degrees

m<A + m<B = 180

(2x - 5) + 3x = 180

5x - 5 = 180

5x = 175

x = 35

Answer:

area = 138 m²

Step-by-step explanation:

radius of large circle = 12 m

radius of small circle = 10 m

large circle area = πr² = (3.14)(12²) = 452.16 m²

small circle area = πr² = (3.14)(10²) =314 m²

452.16 - 314 = 138.16 m²

Answer:

Gamba obtained 75 more votes than Ahmed.

Step-by-step explanation:

Given that in the finals of a singing contest at Greenvale Middle School, 300 students voted on which contestant they liked best, and Gamba got 35% of the votes while Ahmed got 10%, to determine how many more votes did Gamba get than Ahmed the following calculation should be performed:

(300 x 0.35) - (300 x 0.10) = X

105 - 30 = X

75 = X

Thus, Gamba obtained 75 more votes than Ahmed.

Answer:

Step-by-step expVivian’s house area can be split into two rectangles: FLSU and MNSR.

area of rectangle FLSU

= length × width

= (FU) × (FL)

= 30 × 25

= 750 square feet

area of rectangle MNSR

= length × width

= (MS) × (MN)

= 38 × 25

= 950 square feet

area of Vivian’s house

= area of rectangle FLSU+ area of rectangle MNSR

= 750 square feet + 950 square feet

= 1,700 square feet

Step-by-step explanation:

Answer:

b. the average calorie count of a large number of fruit smoothie brands has a sampling distribution that is close to Normal.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Applying to this question:

The distribution of the number of calories in fruit smoothies is strongly skewed to the right. However, in a sample with a large number of fruit smoothies, the sampling distribution will be approximately normal, so the correct answer is given by option B.

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total number of groups be = A

Now , the number of groups of 1/4 in 3 is calculated by

Number of groups of 1/4 in 1 is

1/4 x 4 = 1

Therefore , the number of groups of 1/4 in 1 is = 4 groups

So , the equation will be

The number of groups of 1/4 in 3 = 3 x the number of groups of 1/4 in 1

Substituting the values in the equation , we get

The number of groups of 1/4 in 3 = 3 x 4 groups

The number of groups of 1/4 in 3 = 12 groups

Therefore , the value of A is 12 groups

Hence , The number of groups of 1/4 in 3 are 12 groups
