13. t plus the product of three and t​
Sindrei [870]

Answer:

4t

Step-by-step explanation:

Let's form an equation here just to put it visually.

So it would be t+3*t

We can also write this as t+3t (If they're right next to eachother, it still indicates multiplication)

Now we can do t+3t which is 4t

If this doesn't make sense, then you can look at it this way

You do 1t+3t and since they're like terms, you can combine them and do 4t.

A square has an area of 36 m2. The square is scaled in such a way that its area is increased by 28 m2. What is the approximate f
Naddika [18.5K]

Answer:

The length has increased by a factor of 4/3 or 1 1/3

Step-by-step explanation:

To find the initial length.: root 36.

Root 36 = 6

Then to find the increased version, first find the area: 36 + 28 = 64

Now, the length.

Root 64 = 8

To find the factor it increased by:

6x = 8

x = 8/6 = 4/3

The length has increased by a factor of 4/3 or 1 1/3

Tim is dividing up a 2 ½ pound bag of nuts into smaller portions.
blondinia [14]

9514 1404 393

Answer:

  a.  10

  b.  5

  c.  3 with 1/4 pound left over

Step-by-step explanation:

You can find the number of 1/4 pound bags by dividing 2 1/2 pounds by 1/4 pound. In decimal, this is obvious:

  2.5/0.25 = 10

Using fractions, it is ...

  (2 1/2)/(1/4) = (5/2)/(1/4) = (10/4)/(1/4) = 10/1 = 10

__

a) Tim can make 10 1/4-pound bags from 2 1/2 pounds.

__

b) It is worthwhile to note that a 1/2-pound bag is equivalent to two 1/4-pound bags. So, the number of 1/2-pound bags will be 10/2 = 5.

Tim can make 5 1/2-pound bags from 2 1/2 pounds.

__

c) It is worthwhile to note that a 3/4-pound bag is equivalent to three 1/4-pound bags. So, the number of 3/4-pound bags will be 10/3 = 3 1/3.

Tim can make 3 3/4-pound bags from 2 1/2 pounds, with 1/4 pound left over.

2. A set of data consists of the number of years that applicants for foreign service
Bad White [126]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the regression equation :

y = 31.6 + 10.9x

x = the number of years of study ;

y = the grade on the test.

The predicted is y which is also the same as the response variable, hence, the response variable is grade on the test

The predictor variable is x, which is the independent variable, which is the number of years of study.

From. The regression output given ;

The slope which is the Coefficient of the predictor variable is 10.9 which means that for every unit change in number of years of study, the grade on test increases by 10.9

The intercept which is the constant value, 31.6, means, the least a person can get in the get in grade is 31.6 (at x = 0)
