Answers

Answer 1
Answer:

The algebraic expression is a difference between two terms will be 5y - 7. Thus, the correct option is A.

What is Algebra?

Algebra is the study of algebraic expressions, while logic is the manipulation of those concepts.

An algebraic expression that is created by removing two terms is known as a difference between two terms. Only one of the suggested expressions corresponds to this description:

⇒ 5y - 7

The difference between the terms 5y and 7, which are being subtracted from one another, is represented by this equation.

Thus, the correct option is A.

Edgar Anderson earns $300 a week plus a 15% commission only on sales he makes after his first $1000 in sales. If Mr. Anderson’s sales for one week are $2,500, what is his gross pay for that week?

Answers

Answer:

$525

Step-by-step explanation:

Edgar Anderson earns in a week = $300

He also earns commission on the sales he makes after his first $1,000 = 15%

Mr. Anderson's sales for one week are = $2,500

His commission is on his sale = 2,500 - 1,000 = 1,500

He earns commission = 15% of 1,500

                                     = 0.15 × 1,500

                                     = $225

His gross pay for that week = $225 + $300 = $525

Mr. Anderson's gross pay for that week is $525.

His gross pay would be $525.00

2500-1000=1500
1500 x .15 = 225.00
225+300= $525.00

What is the volume of a hemisphere with a radius of 9.7 cm, rounded to the nearest tenth of a cubic centimeter? please i need help ill do a zoom call and i'll give you all my Branly points if uu help me.

Answers

The volume of a hemisphere is 1910.52 cm^(3).

What is volume of a hemisphere?

A hemisphere is half of a full sphere, we can calculate the volume of a hemisphere just by halving the volume of the complete sphere.

So, we can calculate the volume of a hemisphere by using the following formula,

$V=(2)/(3)\pi {{r}^(3)}$

Here, r is the radius, V is the volume of hemisphere.

So,

It is given that the radius is 9.7 cm.

We have to find V.

So,

$V=(2)/(3)\cdot 3.14\cdot {{\left( 9.7 \right)}^(3)}$

V=1910.52

Hence, the volume of hemisphere is $1910.52\text{ c}{{\text{m}}^(3)}$.

Answer:

volume of hemisphere =1912.26cm^3

Step-by-step explanation:

radius(r)=9.7cm

now volume of hemisphere=(2/3)πr^(3)

                                           =(2/3)*(22/7)*(9.7)^3

                                            =(2/3)*(22/7)*912.673

                                              =(2/3)*2868.40086

                                             =1912.26cm^3

What is the surface area of a rectangular prism with a base length of 8 yd, a base width of 6 yd, and a height of 4 yd? A. 104 yd2 B. 112 yd2 C. 192 yd2 D. 208 yd2

Answers

SA=2(LW+LH+WH)
L=8
W=6
H=4
SA=2(8*6+8*4+6*4)
SA=2(48+32+24)
SA=2(104)
SA=208 yd^2

answer is D

How to find the surface area of Rectangular Prisms:

Find the area of two sides (Length*Height)*2 sides;
Find the area of adjacent sides (Width*Height)*2 sides;
Find the area of ends (Length*Width)*2 ends;
Add the three areas together to find the surface areais .


The surface area of a rectangular prism is 8*6 + 6*4 + 8*4 = 48 + 24 + 32 = 72 + 32 = 104 yd2.
