Answer:

The elevation of town B is = -91

Step-by-step explanation:

From the question, we have the elevation of twin A as -13

The elevation of town B is 7 times lower than this

The equation representing this is as follows;

Elevation of town B = 7 * (-13)

= -91

Answer:90%

i used my calculator but basically i added the numbers up and divided them by 75 which gave me 10% so that is the percent of the oranges so you substracted by the whole (100%) and it gives you the answer, your welcome.

The 90% of the fruit is apples.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

Jamal has 75 oranges and 675 apples.

The total fruits are 750.

Let n be the percentage of the fruit is apples.

So,

675 = n x 750/100

n = 67500/750

n = 90%

Therefore, the percentage is 90%.

Step-by-step explanation:

Given:

The length of a TV is [tex]\frac{16}{9}[/tex] times the width.

Length of the new TV = 32 inches.

To find:

The width of the new TV.

Solution:

Let x be the width of the new TV.

It is given that, the length of a TV is [tex]\frac{16}{9}[/tex] times the width.

[tex]Length=\dfrac{16}{9}x[/tex]

Length of the new TV = 32 inches.

[tex]32=\dfrac{16}{9}x[/tex]

[tex]32\times \dfrac{9}{16}=\dfrac{16}{9}x\times \dfrac{9}{16}[/tex]

[tex]18=x[/tex]

Therefore, the width of the new TV is 32 inches.

Answer:

238 nickels

282 pennies

Step-by-step explanation:

N =Nickels    

P= Pennies

20 nickels = 1 dollar

100 pennies = 1 dollar

N+P = 520

P=( 520-N)

0.05(N) +0.01(520-N) = $14.72

Multiply by 100 to avoid decimals:

5 N +1(520-N) = 1,472

5N +520 -N = 1,472

4N = 952

N = 238  (238/20 = 11.9)  $11.9

520-238 = 282 pennies (=$ 2.82)

238 + 282 = 520

$11.9 + $2.82 = $ 14.72

Answer:

Step-by-step explanation:

In the US, the most common eraser that is sold are the regular Pink Press erasers. These, as shown in the image below, are roughly 2.2 inches long. The most commonly used paper clip size is about 1.375 inches long. Assuming that these are the items that Dave is using to measure, then we can calculate the size of the calculator which is 2 erasers long...

2.2 + 2.2 = 4.4 inches long

The calculator is roughly 4.4 inches long, we can also divide this number by the length of the paper clip to find out how many paper clips make up the calculators length

4.4 / 1.375 = 3.2 paper clips

Step-by-step explanation:

Answer:

3. 137

4. A, C, E

Step-by-step explanation:

3. If ABC and DEF are similar, the corresponding angles are similar. This means that A = D, B = E, and C = F

Since A = 64, D also equals 64

Then, you have the angle measures of D and F so you can add them to get the angle measure of G.

64 + 73 = 137 degrees.

4. Go through each and see if it works:

A. This is true, it's a triangle rule

C. The interior angles of a triangle always add up to 180

E. Both add up to 180

5. Neither student is correct. Julie isn't correct because the angles are actually all the same, but you don't know if they are congruent because you don't have any side lengths. Ramiro isn't correct because there is enough information to figure out that the 3 angles are the same, meaning that they are similar.

Answer:

X = - 1

Y = 0

Step-by-step explanation:

Answer:

Option B

Step-by-step explanation:

From the graph attached,

x-intercepts of the graph are x = -1, 2 and 5

y-intercept of the graph is y = 10

Since, x intercepts of a graph define the zeros of the function (y = 0)

Therefore, (x + 1), (x - 2) and (x - 5) are the zero factors of the given graphs.

And the equation of the function will be,

f(x) = a(x + 1)(x - 2)(x - 5)

Since, -intercept of the function is y = 10

Therefore, for x = 0,

y = a(0 + 1)(0 - 2)(0 - 5) = 10

a(10) = 10

a = 1

So the function representing the graph is,

f(x) = (x - 1)(x + 2)(x - 5)

Option B will be the answer.

Answer:

We know that Salma will run less than 35 miles in total this week.

So if t represents the number of miles that Salma runs, we have the inequality:

0mi ≤ t < 35 mi

(where the first part comes because she can not run a number of negative miles, but this is trivial.)

We know that she already ran 18 miles, then we have now the inequality:

t + 18mi < 35mi

Now we need to isolate S

t < 35mi - 18mi

t < 17mi

So she can run any number of miles that is smaller than 17 miles.

For example, she could run 10 miles, 14 miles, 4.5 miles, etc.
