I will you brainiest if you can answer this

For this case we have an expression of mixed numbers:

$5 \frac {1} {2} = \frac {2 * 5 + 1} {2} = \frac {11} {2}\\4 \frac {1} {4} = \frac {4 * 4 + 1} {4} = \frac {17} {4}\\6 \frac {3} {4} = \frac {4 * 6 + 3} {4} = \frac {27} {4}$

Rewriting the expression we have:

$- \frac {11} {2} - \frac {17} {4} -\frac {27} {4} =$

Remember that equal signs are added and the same sign is placed.

$- \frac {11} {2} - \frac {44} {4} =\\- \frac {11} {2} - \frac {22} {2} =\\- \frac {33} {2}$

Answer:

$- \frac {33} {2}\\-(15 \frac {3} {2})$

A random sample produced the pie chart below. The chart gives percentages of students that under reported, accurately reported,

tiny-mole [99]

Answer:

The correct option is A.

Step-by-step explanation:

Total number of students at the school is 2,500.

In the given pi chart Pink, Yellow and Sky Blue color represent the percentage of students that under reported, accurately reported, and over reported their heights respectively.

From the graph we can conclude that the yellow portion is approximately one fifth of whole circle. It means the number of students that accurately reported their height is one fifth of total number of students.

$2500\times \frac{1}{5}=500$

Therefore the number of students that accurately reported their height is 500. Option A is correct.

Factorization of nine using exponents from least to greatest

natta225 [31]

The only way to write 42 as the product of primes (except to change the order of the factors) is 2 × 3 × 7. We call 2 × 3 × 7 the prime factorization of 42. It turns out that every counting number (natural number) has a unique prime factorization, different from any other counting number. This fact is called the Fundamental Theorem of Arithmetic. Fundamental theorem of arithmetic

In order to maintain this property of unique prime factorizations, it is necessary that the number one, 1, be categorized as neither prime nor composite. Otherwise a prime factorization could have any number of factors of 1, and the factorization would no longer be unique.

Prime factorizations can help us with divisibility, simplifying fractions, and finding common denominators for fractions.

Find the surface area of the prism.

weqwewe [10]

Answer:

160 m²

Step-by-step explanation:

The surface area of the prism is the sum of the area of its surfaces. This prism has 5 surfaces, namely the front, back, right, left and bottom surface.

Area of front surface

Area of triangle= ½ ×base ×height

Base= 6 m

Height= 4 m

Area= 6(4)= 24 m²

Area of back surface

Area of back surface

= area of front surface

= 24 m²

Area of right surface

Area of rectangle= length ×breadth

Length= 7 m

Breadth= 5 m

Area= 7(5)= 35 m²

Area of left surface

Area of left surface

= area of right surface

= 35 m²

Area of bottom surface (base of prism)

Area of rectangle= length ×breadth

Length= 7 m

Breadth= 6 m

Area= 6(7)= 42 m²

The total surface area can be found by adding all of the surface areas we have found earlier.

Total surface area

= 24 +24 +35 +35 +42

= 160 m²

The product of -3 and the quantity of the difference of a number, x, and 10 is at least -3.

Sonja [21]

-3(x - 10) > = -3 <== ur inequality
-3x + 30 > = -3
-3x > = -3 - 30
