Answer 1

Answer:

c must be -4

Step-by-step explanation:

x^2 - 5x + c = 0 is a quadratic whose coefficients are a = 1, b = -5 and c = c.

The discriminant is b^2 - 4ac, and we know that b^2 - 4ac = 41.

Substituting -5 for b and 1 for a, we get:

(-b)^2 - 4(1)(c) = 41, or 25 - 4c = 41, or -4c = 16.  Thus, c must be -4, and the quadratic is

x^2 - 5x - 4

The weight (in kg) of cubical block of ice 75 cm in length (if one cubic metre of ice weight is 80 kg) is

(1) 35

(2) 42.50

(3) 33.75

(4) 40

Answers

Answer: The weight = 33.75kg

Step-by-step explanation:

Given that  

one cubic metre of ice weight is 80 kg

which is mathematically written as

1m³ of ice = 80 kg

Therefore 75 cm length of  cubical  block of ice =???

First

changing  75 cm to meters, we have  75/100 = 0.75 m

Volume of block = l³= 0.75³ = 0.421875m³

Given that

1m³ = 80kg

0.421875m³=  0.421875 x 80

= 33.75kg

Answers

Answer:

Step-by-step explanation:

There are six faces on the prism:

Two faces are 7 cm by 10 cm, area = 7×10 = 70 cm² each

Two faces are 7 cm by 3 cm, area = 7×3 = 21 cm² each

Two faces are 10 cm by 3 cm, area = 10×3 = 30 cm² each

surface area = 2(70) + 2(21) + 2(30) = 140 + 42 + 60 = 242 cm²

Step-by-step explanation:

to understand thisyou need to know about:trianglesequationPEMDAStips and formulas:a straight line contains 180°a triangle contains 180°let's solve:

equation for x

according to the question

110°+x=180°

x=180°-110°

x=70°

equation for y

according to the question

[tex]11 {0}^{o} + {40}^{o} + y = 18 {0}^{o} [/tex]

[tex]15 {0}^{o} + y = 180^{o} [/tex]

equation for z

according to the question

90°+x+z=180°

90°+70°+z=180° (since x=70°)

160°+z=180°

z=180°-160°

z=20°

Answer:

X= 70

Z= 20

y= 30°

Step-by-step explanation:

Finding X:

Sum of angle in a straight line is 180

Therefore X = 180-110

Finding z:

Sum of angle in triangle is 180, and it’s a right angled triangle (90°)

Z= 180-(x+90)

Z= 180-( 70+90)

Finding y, look at the big triangle ABC:

There’s a right angle and <C is 40°,

Therefore <B is 180-(40+90)= 50°

<B= y + z

50° = 20° + y

y= 30°

How do you write 28/50 as a percentage?

Answers

28/50 * 100 = 56%

when finding percentage always multiply by 200

Answer: 56%

Step-by-step explanation: To write the fraction 28/50 as a percent, remember that a percent is a ratio that compares a number to 100.

So we need to find a fraction that's equivalent

to 28/50 that has a 100 in the denominator.

To do this, we set up a proportion.

So we have 28/50 = n/100.

To find the value of n, we first find the fraction that

is equivalent to 28/50 that has a denominator of 100.

If we multiply both the numerator and denominator of

28/50 by 2, we can see that 28/50 = 56/100.

So 28/50 is equal to 56/100 or 56%.

Emma is a sales clerk at a bicycle shop. She is paid $6.25 per hour for 30 hours work week plus a commission of 8% of sales. In one week, her sales were $2319.75, what is her gross weekly earning?

Answers

Answer: $‭373.08‬

Step-by-step explanation:

First find out what she earned from her normal wages.

She is paid $6.25 per hour for 30 hours in a week. Her weekly pay is therefore:

= 6.25 * 30

= $187.50

She then gets 8% of her sales as commission. Her commission is therfore:

= 8% * 2,319.75

= $‭185.58‬

Her gross pay is therefore:

= Weekly pay + Commission

= 187.50 + 185.58

= $‭373.08‬

9. A triangle has an area of 36 yd2 and a base of 3 yd, what is the height of the triangle?

Answers

Answer:

24yards

Step-by-step explanation:

Answer:

[tex]\boxed {\boxed {\sf 24 \ yards}}[/tex]

Step-by-step explanation:

The formula for a triangle's area is:

[tex]a= \frac{1}{2} bh[/tex]

We know the area is 36 square yards and the base is 3 yards.

[tex]a= 36 \ yd^2 \\b= 3 \ yd[/tex]

Substitute the values into the formula.

[tex]36 \ yd^2 = \frac{1}{2} (3 \ yd )h[/tex]

Divide by 1/2 or multiply both sides by 2.

[tex]2 * 36 \ yd^2 = \frac{1}{2} (3 \ yd )h *2[/tex]

[tex]72 \ yd^2= (3 \ yd)h[/tex]

We are trying to solve for the height, so we must isolate that variable. h is being multiplied by 3. The inverse of multiplication is division, so we must divide both sides by 3 yd.

[tex]\frac {72 \ yd^2}{3 \ yd}= \frac{(3 yd) h}{3 \ yd}[/tex]

[tex]24 \ yd =h[/tex]

The height of the triangle is 24 yards.

Part 1: G)52%  H)28%  I)19%   J)75%   K)95%

Part 2: 88%

Step-by-step explanation: I did math stuff lol, converted the decimal into a percent

Ex: 13/25= 0.52

0.52= 52%

Answer:

g. 52%

h. 28%

i. 19%

j. 75%

k. 95%

l. 88%

Step-by-step explanation:

g. 13/25

The denominator is currently 25. We must multiply it by 4 to reach 100. By converting the denominator to 100, the numerator will give us the answer to the percentage. However, when multiplying one side of the fraction (the denominator), we must also do the same to the other side of the fraction (the numerator).

Hence:

13 × 4 / 25 × 4

52/100

Since the denominator is 100, we can confidently say the answer is 52%

h. 7/25

Multiply by the numerator and the denominator by 4 so that the denominator equals 100.

7 × 4 / 25 × 4

28/100

28%

i. 19/100

The denominator for this fraction is 100, meaning the percentage is the numerator:

19%

j. 3/4

To get from 4 to 100, we must multiply by 25. What we do to the denominator, we must do to the numerator.

3 × 25 / 4 × 25

75/100

75%

k. 19/20

In order to change the denoninator to 100, multiply the denominator by 5 (20 × 5 = 100). Multiply by 5 to the numerator too to get the percentage.

19 × 5 / 20 × 5

95/100

95%

l. Out of 25 questions, Maria answered 22 correctly. If we write this as a fraction, we would put the total number (of questions) as the denominator with the correctly answered (number of questions) as the numerator:

22/25

We have to convert the denominator to read as 100 instead of 25. To do so, we must multiply 25 by 4. Whatever we do to the denominator, we must do to the numerator which means multiply the numerator by 4 as well.

22 × 4 / 25 × 4
