What is one value of x that makes the equation-16x^2+121=0 true
Answer:
x = ±11/4
Step-by-step explanation:
Rewrite -16x^2+121=0 as 16x^2 - 121=0 and then as 16x^2 = 121.
Take the square root of both sides. This returns 4x = ±11, and so:
x = ±11/4

Jayson wrapped plastic around a carrot shaped like
a cone to create a mold for a project. The carrot had
a slant height of 6 inches and a diameter of 12
inches. Which is closest to the amount of plastic he
will use?
A:226 square inches
B:113 square inches
C:452 square inches
D:678 square inches
Answer:
113.04
Step-by-step explanation:
the formula for the lateral surface area of a cone (all i mean is the area up the sides and not the area of the circle on the of the cone) is the
slant height times r times pi
so put in the variables(diameter/2 = r so 12/2 = 6)
6*6*3.14 = 113.04

Answer:
71.1 degrees
Step-by-step explanation:
The side opposite angle A is 35 and that adjacent to angle A is 12. The trig function that connects A and these two sides is
tan A = (opp) / (adj)
which here is
tan A = 35/12. Find A using a calculator's arctan function:
arctan 35/12 = 1.25 radian or 71.1 degrees.
Split £180 into a 7 : 5 ratio
The splitted bill of £180 into a 7 : 5 ratios are £105 and £75 respectively.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, A bill has to be split £180 in the ratio of 7 : 5.
∴ One part is (7/7 + 5)×180.
= (7/12)×180.
= 105.
Another part is (5/7 + 5)×180.
= (5/12)×180.
= 75.

265.6 is what percent of 256 rounded to the nearest tenth
Answer:
103.75 %
Step-by-step explanation:
[tex] \frac{265.6}{256} \times 100[/tex]
Take 265.6 and divide it by your original number of 256. Now multiply this resultant by 100 to see your final answer rounded to the nearest 10th.
Answer:
256:265*100 =
(256*100):265 =
25600:265 = 96.6
Step-by-step explanation:
Percentage solution with steps:
Step 1: We make the assumption that 265 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$x.
Step 3: From step 1, it follows that $100\%=265$100%=265.
Step 4: In the same vein, $x\%=256$x%=256.
Step 5: This gives us a pair of simple equations:
100%=256(1)
x%=256(2)
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%);
100%/x% = 256/256
Step 7: Taking the inverse (or reciprocal) of both sides yields
x%/100%=256/256
-->x=96.6%
Therefore, 256 is 96.6% of 265

Which pair of triangles can be proven congruent by SAS?
Third pair of triangles is congruent by SAS.
What is congruency?In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.
If any two sides and angle included between the sides of one triangle are equivalent to the corresponding two sides and the angle between the sides of the second triangle, then the two triangles are said to be congruent by SAS rule.
In the third pair, this rule is visible. Two pair of sides are equal to each other and the angles formed at the common vertex of the two sides are equal. Hence, the two triangles are congruent by SAS.

Answer:
Probability (Fraction, Decimal, Percentage) = 1/8 , 0.125 , 12.5%
Step-by-step explanation:
Total cards = 8 ; numbered 'three, four, five, six, seven, eight, nine, ten'
Prob (Card with number three) = card with no. three / total cards = 1/8
Prob (Card with number four) = card with no. four / total cards = 1/8
Similarly , Prob (A Card with any other number) = 1/8
Fraction Probability = 1/8 ; Decimal Probability = 0.125
