Answer:
a= -3, b= 4 and c= -5
ab + c = (-3)4+(-5) = -12 -5 = -17
Answer:
answer is -17
Step-by-step explanation:
all you have to do for this question is to plug the values for a, b, and c in the question.
ab + c would be
(-3)*4+(-5)
-12+(-5)
= -17
therefore the answer is -17

1. Trevor's fitness trainer recommends that Trevor drink 8 fluid ounces
of water 8 times a day. Trevor has a water bottle that holds 1 1/4 pints
of water when filled. Today, he has filled the water bottle three times
and drank all of the water each time. Trevor claims that he drank the
total amount of water recommended by his fitness trainer. Explain
why Trevor's claim is not true. (Remember 8 ounces = 1 cup; 2 cups
1 pint)
=
Answer: Trevor drinks 3 3/4 pints against his coach's 4 pints
Step-by-step explanation:
8 ounces per day x 8 times = 64 ounces = 8 cups = 4 pints
Water bottle holds 1 1/4 pints x 3 = 3 3/4 pints.

What is the surface area of the regular pyramid given below?
A. 144 units2
B. 352 units2
C. 176 units2
D. 208 units
Answer:
The surface area of the pyramid is 208 units²
Step-by-step explanation:
Luckily, since this is a square pyramid, we only need to find two numbers. These two numbers are the area of the base and the area of one triangular side. After we find them, we need to add them all together.
First, the base:
Since it's a square, we can just do 8 · 8 and get 64. Now we have one of the two needed numbers.
Second, one of the triangles:
To start, we multiply the base (8) by the height (9) giving us 72. After we divide that by 2, we have the area of the triangle, which is 36. Now we have the second number down. Now we can...
Finally, add them all together:
Now that we have the area of the base (64) and one of our triangles (36), we need to add them together. We add the base once and the triangle four times (because there are four triangles) to get the total surface area. Our expression looks like this:
64 + 36 + 36 + 36 + 36
After doing some simplifying, we get our final number, 208.
The surface area of the pyramid is 208 units²
The surface area of the regular pyramid in the diagram is 208 units².
What is the Area of a Pyramid?The surface area of the pyramid = Sum of area of the triangular faces + Area of the square base.
Surface area of the pyramid = 2bh + b²
Where b is the base
and h is the perpendicular height of each triangular faces
In the given diagram,
b = 8
h = 9
∴ Surface area of the pyramid = 2×8×9 + 8²
Surface area of the pyramid = 144 + 64
Surface area of the pyramid = 208 units²
Hence, the surface area of the regular pyramid in the diagram is 208 units².

There are 2200 students in a school. 52.5% of them are male. How many are female?
___________________________________
Total number of students=2200
Total percent of male=52.5%
Total percent of female=100%-52.5%
=47.5%
Total number of female= 47.5% of 2200
=47.5/100*2200
=1045
So the total number of female is 1045

A text message can have a maximum of 160 characters. If Daisy has typed 3 sentences with 45
characters each, then which equation can be solved to find the number of characters she can still
type. Let "c" equal number of Daisy characters left.
Answer:
c = 160 - 3(45)
Step-by-step explanation:
if c = the number of characters left;
160 = maximum number of characters that can be used in a text
3*45 = number of characters in sentences already used. (There are 3 sentences of 45 characters.)
(# of char left) = (max # char) - (# char already used) so:
c = 160 - 3*(45)
c = 160 - 135
c = 25
There are currently 4 people signed up to play on a baseball team. The team must have at least 9 players.
Which of the following graphs includes the possible values for the number of people who still need to sign up for the team?
Answer:

NEEEDDD HHEELLPP NNOOWW. URGENTT giving 100 points and brainliest The mass of an empty jar is 470 g. 6 marbles are placed in the jar. The total mass of the jar and marbles is now 1.1 kg. Two of the marbles are removed. What is the mass of the jar and marbles now?
Answer:
890
Step-by-step explanation:
Well, first we should put 1.1 kg into grams (1 kg = 1000g)
1.1kg= 1100g
[tex]1100-470= 630[/tex] this is how much was added by the marbles
630/ # of marbles gives the mass of each marble
[tex]\frac{630}{6} = 105[/tex]
each marble has a mass of 105 g
1100- 2m(marble)=
1100-2*105
1100-210=
890
Answer:
890 grams
Step-by-step explanation:
Remember that one kilogram is equal to 1000 grams. Therefore, 1.1 kilograms is equal to 1,100 grams. (remember 0.1 means one tenth, and one tenth of 1000 is 100)
1,100 grams is the total measure of the jar with the marbles. Subtract the weight of the jar, 470 grams, to find the measure of the marbles.
1100 - 470 = 630
Now, we can divide 630 grams by the total number of marbles, 6, to find the weight of each marble.
630/6 = 105.
Therefore, each marble weighs 105 grams.
Now, we know that two marbles were removed from the jar that weighs 1100 grams.
Multiply 105 by 2 to find the number of grams that were taken out of the jar:
105*2 = 210
Now, we subtract 210 from 1100
1100 - 210 = 890 grams

The five triangle congruence are sss, sas, aas, asa and hl criteria. Fully explain why aaa is not a triangle congruence criteria
Answer:
As you may know, the addition of all the interior angles of a triangle always adds up to 180°.
So if we know two angles of the triangle, A1, and A2, we can find the third angle as:
A1 + A2 + X = 180°
X = 180° - A1 - A2.
Se with only knowing two angles, we can find the third angle.
So aaa is a criteria equivalent to aa.
Now, the problem with this criteria is that also works for finding similar triangles (for example, an equilateral triangle of sides 10 and an equilateral triangle of sides 20 are similar, as the angles are the same, but are not congruent, as the length of the sides is different) and this happens because we only have information of the angles and know nothing of the sides.

The scatter plot shows the relationship betweeen the number of hours students spend watching television and the numer of hours they spend with family each week.
What is the y-intercept of the line of best fit and what does it represent?
11.5 hours; the number of hours students spend with family in a week when they do not watch television
9.2 hours; the number of hours students watch television in a week when they do not spend time with family
9.2 hours; the number of hours students spend with family in a week when they do not watch television
11.5 hours; the number of hours students watch television in a week when they do not spend time with family
9.2 hours; the number of hours students watch television in a week when they do not spend time with family
Step-by-step explanation:
We are given,
The x-axis represents the time spent with family and the y-axis represents the time spent on watching television.
Now, y-intercept is the point where the scatter plot crosses y-axis.
From the scatter plot and and according to the options, the data point is located at x= 0 and y= 9.2.
That is, the y-intercept represents that students watched television for 9.2 hours when they do not spend time with their family.
