Can u please answer my question

Answers

Answer 1

Answer: 1st Step:We should first change them all to have a common denominator.
2nd Step:We should find the least common multiple
4×1=4 8×1=8 16×1=16
4×2=8 8×2=16
4×3=12
4×4=16
LCM is 16

$(1*4)/(4*4)$ + $(1*2)/(8*2)$ + $(1)/(16)$
$(4)/(16)$ + $(2)/(16)$ + $(1)/(16)$
$(7)/(16)$

$(7)/(16)$ is the fraction of the page that is used in total.

Answer 2

Answer: turn the denominators into the same number by multipling them
same to top as to bottom so
1/4 =4/16
1/8= 2/16
1/16 stays the same

add together to get 7/16

Answers

C.

By plugging in the numbers into the equation, 8 = 250(k), we can determine that 8 ÷ 250 = 0.032.

Swimsuit discounted 65% on sale for $20.30.

Answers

Answer: The original price of swimsuit is $58.

Step-by-step explanation:

Since we have given that

Sale price of swimsuit = $20.30

Rate of discount =65%

Let the original price of swimsuit be 'x'.

According to question,

$(100-65)/(100)* x=20.30\n\n(35)/(100)* x=20.30\n\nx=(100* 20.30)/(35)\n\nx=\$58$

Hence, the original price of swimsuit is $58.

Original price of the swimsuit = x

If something was discounted 65%, that means you are paying 35% for it.
(100% - 65% = 35% or 0.35)

x(0.35) = 20.30

divide both sides by 0.35

x = 58

The swimsuit was originally 58 dollars.

What is the equation of the line described below written in slope-intercept form? the line passing through point (-1, 5) and parallel to the line whose equation is x + y = 10

A. y = x - 4
B. y = x + 4
C. y = -x + 4

Thank you to anyone who helps!

Answers

The line it is parallel to is x + y = 10, but you can put that into slope-intercept form by subtracting x and get y = 10 - x. This is all the working you need to do because the only answer given that has a negative slope is C. y = -x + 4, and parallel lines always have the same slope, so your answer is C. I hope this helps!

Answer:

y = -x + 4

Ok so,
#1 is a triangular pyramid as we can see.
The surface area formula of a pyramid is:
S.A = Area of base + $(1)/(2)$ × perimeter of base × slant height
The base is 8 cm ( 4cm + 4cm = 8cm)
Height of the triangle is 3.5 cm
Area formula of a triangle is:
A = $(1)/(2)$ bh
P = all sides added together

Substitute them:
S.A = $(1)/(2)$ × 8 × 3.5 + $(1)/(2)$ ×(8 + 8 + 8) × 5
S.A = 14 + 60
= 74 cm²

and #2 is a squared-based pyramid
Same formula applies.
And we know that the area formula of a square is:
A = s²
P = add all sides together

S.A = 2² + $(1)/(2)$ × (2 + 2 + 2 + 2) × 3
= 4 + 12
= 16 ft²
