Answer: b) 5

Explanation:

The equation for the temperature in Fahrenheit is:

t = 5h + 61.4

Where h is the number of hours after 4:00 pm

then if this is compared with a linear equation, the y-intercept is 61.4 Fahrenheit, and the slope is 5 Fahrenheit/hour

Now we want to know by how many degrees Fahrenheit will the temperature rise each hour until 4:00 PM, we need to look at the slope in order to answer this.

We know that the slope is 5 Fahrenheit/hour, so each hour that passes the temperature increases by 5 degrees Fahrenheit.

The right option is b) 5.

in a local fitness club 32% of the members lifted weights, 41% preferred aerobics and 6%preferred both.if a member is chosen at

castortr0y [4]

Members lifted weights: W=32%
Members preferred aerobics: A=41%
Members preferred both: B=6%
Members lifted weights only: Wo=W-B=32%-6%→Wo=26%
Members preferred aerobics only: Ao=A-B=41%-6%→Ao=35%
Find the probability that the member prefers another method neither weights nor aerobics to exercise: N=?

N=100%-Wo-Ao-B
N=100%-26%-35%-6%
N=100%-67%
N=33%

Answer: The probability that the member prefers another method neither weights nor aerobics to exercise is 33%

consider a box sitting in the back of a pickup. the pickup accelerates to the right, and because the bed of the pickup is sticky

ANTONII [103]

Answer:

The pickup accelerates towards right. The box is sticky to the pickup, thus its acceleration is the same, towards right. Its inertia (force) is oposing the acceleration, thus it is towards left. For the box not to move, it is necessary that the truck acts on it with a force towards right. (The two forces of the truck on box and the box inertia (force) equilibrate themselves).

Hope this helps:)

There are 39 students in Ms. Salazar's chemistry class. If Ms. Salazar divides the class into 9 lab groups of 4 or 5 students ea

I am Lyosha [343]

Answer:

3 groups of 5

Explanation:

if x is the number of groups of four, and y is the number of groups of five, then 4x +5y =39 (four students per group of four times the # of groups of four, and 5 students per group times the # of groups of five, which should equal the total amount of students, 39). also, x+y=9. (number of each type of group = 9 groups total).

then, use these two equations and solve for y, by "canceling out" x. there are many ways to do this, but i'm going to use subtraction.

4x-5y=39

x+y=9

you want to change the equation

x+y=9

into

4x+4y=36

by multiplying the whole equation by four. because in order to cancel out the x, you need it to equal zero. in the first equation, its 4x.

so its now

4x-5y =39 MINUS

4x+4y=36

___________

y=3

you can check your work because the remaining 6 groups of four (24 total students) plus the 3 groups of five (15 total students) adds up to equal 36
