Answers

Step-by-step explanation:

A team of biologists tagged 48 seals off the coast of an island.

later they captured a sample of seals from the same area and 15% of them had tags.

Estimate the total number of seals.

15 : 100 : : 48 : x

=4,800/15

=320

The total number of seals is about 320.

Sergio has p paintings in his art collection. He and other local painting collectors agreed to donate a total of 48 paintings to the local museum. In each of the 12 collectors will donate the same number of paintings. How many paintings will Sergio have in his art collection after his donation?

Answers

Answer:

Since there are 48 paintings being donated by 12 collectors, then we can say that each collector will donate 4 paintings.

This means that Sergio will have 4 less paintings then he had before, which was represented by pp . Thus, our expression is now \boxed{p - 4}p−4 .

Answer:

Sergio would have 4 paintings less

Step-by-step explanation:

48 total painting

12 painting collectors donated

They all donated the same amount

So each local painting collector donates the same amount of paintings

so 48 divided by 12 = 4

So each painting collector would donate 4 painting each

We don't know how much painting Sergio had in total before but we do know how much he donated which is 4

Jasmyn uses 42% of a gift card to buy groceries if she spent $67.20 on groceries, how much was on the gift card to begin with

Answers

Answer:

The card was worth $160.

Step-by-step explanation:

It is given that:

Percent of gift card used = 42%

Cost of groceries = $67.20

Let,

x be the total amount on gift card.

42% of x = 67.20

[tex]\frac{42}{100}x=67.20[/tex]

0.42x = 67.20

[tex]\frac{0.42x}{0.42}=\frac{67.20}{0.42}\\x=160[/tex]

Therefore,

The card was worth $160.

if you only have a point and slop you would use the formula- y-y1 = m(x-x1)

with your number the equation would be y-6 = 1/4(x+8)

the eight became a positive because in the equation the x is negative and a negative times a negative is a positive*

you would the solve the equation to be in y=mx+b form and it would be

How do I figure out which statement is true?

Answers

Answer:

A. if table is extendedD. if only the values in the table considered.

Step-by-step explanation:

We can see on the graph of g(x) that y-intercept is (0, 2)

The table doesn't have the value for x = 0 but we can observe that it is exponential function and has the formula:

f(x) = 3^x

We can find its y-intercept:

f(0) = 3^0 = 1

We can compare and see that:

f(0) = 1 < g(0) = 2

So the function g(x) has a greater y-intercept. This is option A.

====

Note: If only the values in the table considered, then correct option is D.

Identify the horizontal asymptote of each graph.
y = 0
y = 1
y = 6

Identify the horizontal asymptote of each graph.
y = 0
y = –3
y = –5

Answers

Answer:

y = 0 and y = -3

Step-by-step explanation:

The horizontal asymptote of each graph is:

1. y=0

2. y= -3

What is asymptote?

An asymptote of a curve y = f (x) that has an infinite branch is called a line such that the distance between the point (x, f (x)) lying on the curve and the line approaches zero as the point moves along the branch to infinity.

1.Given function:

t(x)= [tex]6^{x}[/tex]

If we apply limit x→∞, then we get y=c as horizontal asymptote

So, [tex]\lim_{x \to \infty} 6^{x}[/tex]= 0

Hence, the asymptote will by y=0.

2. Given function:

t(x)= [tex]5^{x}[/tex]-3

If we apply limit x→∞, then we get y=c as horizontal asymptote

So, [tex]\lim_{x \to \infty} 5^{x} -3[/tex]= -3

Hence, the asymptote will by y=-3.

I think the answer is no. Because when you would subtract you wouldn’t get 3. If you subtract 167 - 24 you get 143 but if you keep subtracting you get -1 is the lowest. Before -1 you get 143, 119, 95, 71, 47, 23, then immediately goes to -1.

What is the surface area of a cuboid with sides measure 7 in, 3 in and 5 in?

Answers

The surface area the cuboid is 142 inches²

The surface area of the cuboid is given as:

= 2lw + 2lh + 2hw

where, l = length

h = height

w = width

Therefore, the surface area of the cuboid given will be:

= 2lw + 2lh + 2hw

= 2(7×3) + 2(7 × 5) + 2(3 × 5)

= 2(21) + 2(35) + 2(15)
