Answer:
c. 150
Step-by-step explanation:
20 times 15 is 300
subtract 300 from 450
Question
Which expressions are less than 7/8? Choose all answers that apply:
a) 7/8 x 9/15
b) 7/8 x 3/4
c) 7/8 x 9/9
d) 7/8 x 4/3
Answer:
a) 7/8 x 9/15
b) 7/8 x 3/4
Step-by-step explanation:
We are asked to find which expression are least than 7/8
Solving 7/8 = 0.875
We would evaluate the given option one after the other.
a) 7/8 x 9/15
= 63/120 = 0.525
b) 7/8 x 3/4
= 21/32 = 0.65625
c) 7/8 x 9/9
= 7/8 × 1 = 7/8 = 0.875
d) 7/8 x 4/3
= 7/6 = 1.1666666667
Therefore, from the above calculation, the expressions are less than 7/8 are
option a) a) 7/8 x 9/15 and b) 7/8 x 3/4
Answer:
(x-3)^2+(y+2)^2=144
Step-by-step explanation:
The table represents the exponential function:
<h3>
Which function is represented by the table?</h3>
Here we have the table:
x y
-1 1/11
0 1
1 11
2 121
3 1331
Some things that are useful to identify this as an exponential equation are:
For any real number a different than zero:
With these three things, we conclude that we have an exponential equation, because when we evaluate in x = -1, we have a rational number.
When we evaluate in x = 0 we have 1.
Such that the function is:
Notice that:
And so on.

Answer:
1) x+2x+x+3 = 23
4x+3=23
4x=20
x=5
2) a_ radius × radius × pi = the area
4×4×3= 48
b_ diameter × pi= the circumfrence
8×3 = 24
3) a) 34_10=24
24÷3=8
b) _24_(_48)= 24
4) a) 2x=9_5
2x=4 => x=2
b)X/3 =12
x= 36
5) x. _2.
y. 3_(_2)=5
x. 0
y. 3_0=3
x. 3
y. 3_3=0
